Price cut: helpless to continue. The price drop of LED display terminal products best reflects the helplessness of the industry. A company once said that the average price per square meter of LED full-color display products in 2009-2011 was 12,400, 12,000, and 10,700 respectively. , The average selling price in 2011 decreased by 13.71% compared to 2009. The company did not point out the price of its products in 2012 and 2013. In fact, according to the average selling price in the market, the price per square meter of LED full-color displays ranges from several thousand yuan. The price is publicly bid by the manufacturer. Depending on the material and process, taking outdoor P10 as an example, the price per square meter ranges from 4,000 to 10,000 yuan. If it is a wholesale indoor full-color display, the price is even lower. It can be seen that the continued decline in the price of LED display products in 2013 is a manifestation of industry competition, and this trend will continue.
Second, run off, in 2013, the living environment of LED display companies is not optimistic. Especially for small and medium-sized enterprises that do not have scale advantages and product advantages, it is even more difficult to find a balance in the cracks. As the price of LED displays is becoming more and more transparent, and the payment cycle is getting longer and longer, the company doing project engineering has to deal with the entanglement of customers, but also take responsibility for the supplier. Therefore, once bad debts or product problems are discovered, it may be possible As a result, the entire enterprise cannot be turned around, and finally it has to go bankrupt. Big Horizons, Haobo, Vision Light, Everlight, Shifang, and other billion-dollar enterprises are also unable to escape bad luck, and the impact of their bankruptcy is huge, leaving behind a lot of debts. In the end, innocent employees and suppliers are injured. NS.
Third, channels: continue to be hot. Channel competition has always been a must for LED lighting companies. However, in recent years, LED display manufacturers have also begun to be keen on expanding channels, mainly because display products have become more standardized and large-scale. Whoever can get the support of distributors across the country can cover the national market and expand its influence.
Fourth, expansion: non-stop. Some people say that the LED display industry market competition is so stimulating, how can anyone expand production? This statement is wrong. Not all companies are compressing their own business. On the contrary, the market downturn has eliminated some companies while also giving some companies opportunities. Chips have received many government preferential treatments or direct subsidies for their expansion. Some companies have also continued to expand their production due to industrial needs. The construction of industrial parks is ready for subsequent production. Of course, some manufacturers of wholesale display screens are also constantly expanding production. Although their profits are meager, their business seems to be getting bigger and bigger.
Fifth, subdivision: a common practice. When the argument that the LED display market is saturated began to circulate in the industry, many visionary companies have begun to focus on emerging market segments. The competition of display screens in the conventional field depends on the strength and price of the enterprise, but the more segmented market depends on the technical ability of the enterprise. At present, the LED display industry has gradually opened up some new growth highlights, such as high-density and small-pitch LED displays, and thus put forward the concept of LED super TV; such as outdoor surface-mounted LED displays, which will be outdoor direct-plug displays The future replacement device of the screen.
Sixth, integration: has become a trend. Integration includes horizontal integration and vertical integration. Enterprises can choose the way of integration according to their own development needs. Many companies separate marketing from the two major sectors of display and lighting at the same time, which is a kind of integration; Sanan Optoelectronics and National Star Optoelectronics, through equity participation or establishment of branch companies, spread their antennae throughout the upstream chip, midstream packaging and downstream application fields, which is also a kind of integration; Epistar in Taiwan, China, is using virtual vertical integration as a strategy to strengthen its export on the application side; more display companies are doing integration actions in the form of bundling or alliances with suppliers. In short, integration has become an unstoppable trend in the LED display industry, and it is also a direct contributor to the future market structure.

When selecting and applying Shenzhen LED display, the key points are in these aspects, and the following will give you an explanation: 1. Detailed description of the life of indoor LED electronic screen The service life is 100,000 hours. The technical documents produced by the LED raw material manufacturer indicate that the life of the LED luminous object is 100,000 hours under ideal conditions. The ideal situation means that the LED luminous object will never shine under the condition of constant voltage and constant current power supply in the laboratory. By the time it does not shine at all, 100,000 hours will be converted into 11 years. The LED display screen currently uses civilian-grade components, and its application life span does not exceed 8 years.
The function of the LED display is the display function. When the LED display is on and can only be seen at night, it cannot be explained that it is up to the standard and has the value of the commodity. A car can run for 15 years, and if it is not used for 3 years, it will be charged. The natural environment and method of application are quite harmful to the life span of the product.
2. Price selection of indoor LED electronic screens The choice of LED display depends on the comparison of the use effect and not simply on the price. Because the prices on the sales market are too chaotic at this stage, many prices are not even the cost of people’s products, which indicates that the raw materials used are not very good, so when customers buy goods, they must grasp the company’s status and a display screen. How much is the cost and price, customers can not only pay for the goods, but pay attention to the useful life and display effect of the LED display.
The LED display is the ultimate fusion of high-tech and news media. It can vividly present the core concepts of beauty and fashion, and it can completely become a new force in stage design, in new stage performances and outdoor advertising. Ways continue to appear, from traditional LED billboards, to solid-color word-moving screens, to today’s wonderful LED displays. With the development trend of the LED manufacturing industry, outdoor media advertising methods have become more and more fashionable, and may become the development trend of urban new media in the next few years.
At this stage, most of the KTV nightclubs, etc. install ultra-clear displays in the rooms. Outdoor LED displays have already occupied 80% of the outdoor media advertising industry’s market share, becoming a new carrier of large and medium-sized outdoor media advertising. 160-degree angle, broadcast-level color saturation, LED color temperature and chromaticity are intelligently adjustable, which is more suitable for long-term watching.
In choosing a high-quality LED display, in addition to considering the quality of the display itself and reliable service, choosing the right LED display product according to different environments and uses is another guarantee. Below we will combine the seaside and riverside environment to understand the choice of LED display.
The most notable features of the seaside and riverside environments are high humidity, strong wind, strong ultraviolet rays, and easy water ingress.
1.Humidity
In the later use process, excessive humidity will cause the PCB board, power supply, power cord and other components of the LED display to be more likely to be oxidized and corroded, resulting in failure. So this requires us to make anti-corrosion treatments on the PCB board when we make LED large screens, such as coating the surface with three anti-paints, etc., and use high-quality accessories for the power supply and power cord. The welding place is the most likely to be corroded. Pay attention to the protection work, especially the outdoor LED display frame, which is easy to rust, it is best to do anti-rust treatment.
2.Wind
Excessive wind, the most direct impact on the installation of the LED display, so before installing the display, we are required to do a good analysis of the force, taking full account of the wind factor.
3.Ultraviolet rays
Strong ultraviolet rays are more likely to cause the aging of the surface of outdoor LED display screens, thereby reducing its lifespan. The selection of excellent materials when making masks is beneficial to resist the damage caused by ultraviolet rays.
4.Waterproof
Usually the waterproofing mainly considers rainwater, and the waterproofing of special environments such as seaside and riverside should be considered more comprehensive. The seaside salinity and humidity are relatively high, and better waterproofing and the pH requirements that can be tested are required. Waterproof and salt-proof from all directions measure.
5.Perspective
This is an easily overlooked factor. In this environment, the viewing angle is usually relatively wide and the audience is relatively wide. When choosing a product, it is necessary to fully consider its main audience to determine the requirements for the viewing angle of the LED display.
When we are installing outdoor led display screens, if the installation is improper, water leakage is likely to occur. So how do we install it to avoid water leakage in the equipment?
This requires everyone to pay attention to the following points:
1.Add backplane and sealant: Some friends are very afraid of trouble. In order to save trouble, they don’t add backplane or backplane without sealant when installing the led display screen. Do you know that, once the time passes, the electronic components will inevitably enter water, and the display will have problems after many years.
2.Leakage port: If the display screen and the back panel are closely integrated, then the water leakage port must be tapped under it. The so-called water leak, to understand it in a simpler way, is used to leak water. To be honest, no matter how closely the front and back of the led display are combined, there is still more or less water in the environment under the years and months. If there is no leakage hole in the lower mouth, the water will inevitably accumulate more and more under the long-term accumulation. If the leakage hole is punched, the water will flow away, which will inevitably play a very obvious waterproof effect.
3.Appropriate wiring: What we need to remember is that when installing the led display, strictly speaking, the plug wiring must use the appropriate wire. Under normal circumstances, it generally obeys the principle of bigger than smaller. In other words, to put it simply, calculate the total wattage of the led display screen and choose a slightly larger wire, which can reduce the probability of causing the circuit to burn out.
1.Only outdoor LED displays can provide large-area advertisements with a minimum of a few square meters, followed by tens of square meters, and a maximum of hundreds of square meters or even thousands of square meters. Such momentum and influence cannot be achieved by other media.
2.Only the outdoor LED display is a tangible entity, where the audience can stay and interact with each other. Such scenes and experiences cannot be achieved by other media.
3.Outdoor LED display screens exist in various public spaces in the city, which can create various environments or functions for people to stay in according to local conditions: make waiting more interesting, make scenery along the way, light up street night views, beautify the image of the city, and keep information at any time Do whatever you want, wherever you want. In short, technology and creativity make the space humane, and the stickiness between people and the media is further enhanced.
4.There are outdoor LED displays in or near major work, consumption and entertainment places in a city. The main roads leading to these places are also covered with outdoor LED displays. Therefore, in the increasingly important localization marketing, The role of outdoor LED display in guiding offline sales and gathering surrounding people is indispensable and immediate.
5.Outdoor LED display has physical and spatial attributes, and its inclusiveness is the strongest. The outdoor LED display is installed on the wall of the city building, and it is installed in a column type, and has various forms. It can seamlessly connect the short time of passing small groups of people, and it can also be used as a conversion port to connect offline and online in real time to achieve cross-screening. Spread.
Outdoor LED displays are in a stage of rapid development and growth. In the future, there will be more and more requirements for outdoor LED full-color displays in the market, and the standards will become more and more stringent. If you do not improve your own quality, It is bound to be eliminated by the industry. However, it is not so easy to make a high-quality outdoor full-color LED display. It is well known that heat dissipation and waterproofing factors affect the stable operation of outdoor LED displays, as well as harsh weather, harmful gas corrosion, ultraviolet light, and dust. Impurities, humidity and other reasons can also cause frequent failures of outdoor display screens. How to fundamentally solve these problems is the key to doing a good job of outdoor LED display.
What is the main difference between constant current and constant voltage of led display?
The main difference between constant current and constant voltage of led display:
The output current of the constant current drive is constant, but the output DC voltage will vary within a certain range with the load resistance. The smaller the resistance is, the lower the output voltage. The larger the resistance, the output voltage is also The higher it is.
The constant voltage drive is that its output voltage is fixed, but its output current will change with the increase or decrease of the load.
Generally speaking, products driven by constant current will be better and more expensive at the same time. Because of the constant current drive product, it has more circuits and chips, so that the current can be kept constant, which increases the service life and stability of the LED display.
Green environmental protection has long been a major theme at this stage. The society is developing rapidly, but environmental pollution is also expanding at any time. Therefore, mankind must protect our homes. At present, various industries are also advocating the manufacture of green environmental products. Then, how LED companies develop full-color LED displays that do not produce light pollution, energy conservation and environmental protection, has become an important issue that LED display companies must deal with.
LED display screens were once widely used on various street corners of the city and became a common symbol to enhance the image of the city. However, while beautifying the image of the city, the strong light on the screen also had a certain negative impact on the night life of urban residents. The LED industry is a “dimming” industry, and the screen “mountain light” is understandable, but from the urban environmental pollution intervention table, it was once reduced to a new type of pollution “light pollution”. Therefore, enterprises should pay attention to the problem of “light pollution” in their consumption and control the brightness setting.
The first control method: adopts an adjustment system that automatically adjusts the brightness.
According to the difference between day and night, according to the environment and time zone of the place, some changes in the display brightness will have a great effect. When the regenerative brightness of the full-color LED display is greater than 50% of the ambient brightness, the eyes will obviously be uncomfortable and “light pollution” will be formed.
Then, through the outdoor brightness collection system, the ambient brightness of the outdoor LED display can be collected at any time, and the LED display control system is applied to receive the system data and automatically convert it to the brightness display of the appropriate environment through the software.
The second control method: multi-level grayscale correction technology.
Ordinary full-color LED display systems use a 10-bit color display layer. Therefore, if the low grayscale and the color are excessive, the color will be displayed stiffly, which will cause the color light inconsistency. The new LED large-screen control system uses a 14-bit color display level, which greatly improves the excessive color hardness, makes people feel the color mild when watching, and prevents the sense of inwarmness to the light.
In terms of power consumption, the luminescence data used by the full-color LED display itself is energy-saving, but part of the display area needs to be used in larger places. If used for a long time, the total power consumption is still very large. Because the required brightness is relatively high. Under the action of these compound factors, the power consumption of the display is quite alarming. Then all the electricity bills borne by advertising companies will also increase exponentially. Therefore, companies can save energy through the following 5 points.
(1) High-efficiency LEDs can be used, and the light-emitting chip does not cut corners.
(2) The use of high-efficiency switching power supplies greatly improves the power conversion efficiency.
(3) Reduce the heat generation and self-cooling design of the screen, and reduce the power consumption of the fan.
(4) Design the entire circuit plan scientifically to reduce internal circuit power consumption.
(5) According to changes in the external environment, the brightness of the outdoor display is automatically adjusted to achieve the effect of energy saving and emission reduction.

Several major characteristics of the LED display market in the Year of the Ox
/in News /by creuviewPrice cut: helpless to continue. The price drop of LED display terminal products best reflects the helplessness of the industry. A company once said that the average price per square meter of LED full-color display products in 2009-2011 was 12,400, 12,000, and 10,700 respectively. , The average selling price in 2011 decreased by 13.71% compared to 2009.

How to buy LED display screens by seaside rivers and riversides?
/in News /by creuviewIn choosing a high-quality LED display, in addition to considering the quality of the display itself and reliable service, choosing the right LED display product according to different environments and uses is another guarantee. Below we will combine the seaside and riverside environment to understand the choice of LED display.

/in News /by creuview1.Only outdoor LED displays can provide large-area advertisements with a minimum of a few square meters, followed by tens of square meters, and a maximum of hundreds of square meters or even thousands of square meters. Such momentum and influence cannot be achieved by other media.
2.Only the outdoor LED display is a tangible entity, where the audience can stay and interact with each other. Such scenes and experiences cannot be achieved by other media.
3.Outdoor LED display screens exist in various public spaces in the city, which can create various environments or functions for people to stay in according to local conditions: make waiting more interesting, make scenery along the way, light up street night views, beautify the image of the city, and keep information at any time Do whatever you want, wherever you want. In short, technology and creativity make the space humane, and the stickiness between people and the media is further enhanced.
4.There are outdoor LED displays in or near major work, consumption and entertainment places in a city. The main roads leading to these places are also covered with outdoor LED displays. Therefore, in the increasingly important localization marketing, The role of outdoor LED display in guiding offline sales and gathering surrounding people is indispensable and immediate.
5.Outdoor LED display has physical and spatial attributes, and its inclusiveness is the strongest. The outdoor LED display is installed on the wall of the city building, and it is installed in a column type, and has various forms. It can seamlessly connect the short time of passing small groups of people, and it can also be used as a conversion port to connect offline and online in real time to achieve cross-screening. Spread.
Outdoor LED displays are in a stage of rapid development and growth. In the future, there will be more and more requirements for outdoor LED full-color displays in the market, and the standards will become more and more stringent. If you do not improve your own quality, It is bound to be eliminated by the industry. However, it is not so easy to make a high-quality outdoor full-color LED display. It is well known that heat dissipation and waterproofing factors affect the stable operation of outdoor LED displays, as well as harsh weather, harmful gas corrosion, ultraviolet light, and dust. Impurities, humidity and other reasons can also cause frequent failures of outdoor display screens. How to fundamentally solve these problems is the key to doing a good job of outdoor LED display.
The main difference between constant current and constant voltage led display
/in News /by creuviewWhat is the main difference between constant current and constant voltage of led display?
The main difference between constant current and constant voltage of led display:
The output current of the constant current drive is constant, but the output DC voltage will vary within a certain range with the load resistance. The smaller the resistance is, the lower the output voltage. The larger the resistance, the output voltage is also The higher it is.
The constant voltage drive is that its output voltage is fixed, but its output current will change with the increase or decrease of the load.
Generally speaking, products driven by constant current will be better and more expensive at the same time. Because of the constant current drive product, it has more circuits and chips, so that the current can be kept constant, which increases the service life and stability of the LED display.
How to make the full-color LED display more energy-saving and environmentally friendly?
/in News /by creuviewGreen environmental protection has long been a major theme at this stage. The society is developing rapidly, but environmental pollution is also expanding at any time. Therefore, mankind must protect our homes. At present, various industries are also advocating the manufacture of green environmental products. Then, how LED companies develop full-color LED displays that do not produce light pollution, energy conservation and environmental protection, has become an important issue that LED display companies must deal with.
LED display screens were once widely used on various street corners of the city and became a common symbol to enhance the image of the city. However, while beautifying the image of the city, the strong light on the screen also had a certain negative impact on the night life of urban residents. The LED industry is a “dimming” industry, and the screen “mountain light” is understandable, but from the urban environmental pollution intervention table, it was once reduced to a new type of pollution “light pollution”. Therefore, enterprises should pay attention to the problem of “light pollution” in their consumption and control the brightness setting.
The first control method: adopts an adjustment system that automatically adjusts the brightness.
According to the difference between day and night, according to the environment and time zone of the place, some changes in the display brightness will have a great effect. When the regenerative brightness of the full-color LED display is greater than 50% of the ambient brightness, the eyes will obviously be uncomfortable and “light pollution” will be formed.
Then, through the outdoor brightness collection system, the ambient brightness of the outdoor LED display can be collected at any time, and the LED display control system is applied to receive the system data and automatically convert it to the brightness display of the appropriate environment through the software.
The second control method: multi-level grayscale correction technology.
Ordinary full-color LED display systems use a 10-bit color display layer. Therefore, if the low grayscale and the color are excessive, the color will be displayed stiffly, which will cause the color light inconsistency. The new LED large-screen control system uses a 14-bit color display level, which greatly improves the excessive color hardness, makes people feel the color mild when watching, and prevents the sense of inwarmness to the light.
In terms of power consumption, the luminescence data used by the full-color LED display itself is energy-saving, but part of the display area needs to be used in larger places. If used for a long time, the total power consumption is still very large. Because the required brightness is relatively high. Under the action of these compound factors, the power consumption of the display is quite alarming. Then all the electricity bills borne by advertising companies will also increase exponentially. Therefore, companies can save energy through the following 5 points.
(1) High-efficiency LEDs can be used, and the light-emitting chip does not cut corners.
(2) The use of high-efficiency switching power supplies greatly improves the power conversion efficiency.
(3) Reduce the heat generation and self-cooling design of the screen, and reduce the power consumption of the fan.
(4) Design the entire circuit plan scientifically to reduce internal circuit power consumption.
(5) According to changes in the external environment, the brightness of the outdoor display is automatically adjusted to achieve the effect of energy saving and emission reduction.
