What is so good about outdoor LED displays?

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 are the heat dissipation methods for indoor high-definition LED displays?

Electronic products will generate more or less heat during operation. If it is very demanding on the environment, then heat dissipation is required. As a professional LED display manufacturer, let us introduce to you What are the heat dissipation methods for indoor high-definition LED displays?

Physical heat dissipation method: fan heat dissipation, which is a relatively common method at present, which has low cost and good effect.

Air fluid mechanics and the shape of the lamp housing can be used to create convective air. This is a cost-intensive method of heat dissipation.

Surface radiation heat dissipation treatment method, the surface of the lamp housing is treated with radiation heat, and the simpler is to apply radiant heat dissipation paint, which can take the heat away from the surface of the lamp housing by radiation.

The thermally conductive plastic shell is filled with thermally conductive material when the plastic shell is injection molded, so as to increase the thermal conductivity and heat dissipation capacity of the plastic shell.

An air conditioner is installed inside the outdoor LED display body to dissipate heat. This method is simple and quick, but the disadvantage is that the cost is high.

Do you know the six major directions for the future development of LED displays?

1.Development towards energy saving

LED (semiconductor light-emitting diode) itself is very energy-saving, its characteristics are: high luminous efficiency, long life, easy control, maintenance-free; it is a new generation of solid cold light source, light color is soft, colorful, colorful, low loss , Low energy consumption, is a green and environmentally friendly product. But when it is made into an LED display, the power consumption is not small. The working voltage of the LED is generally 3.2V, and the maximum working current is 0.02A, which means that the maximum power consumption is 0.06W. However, large LED screens are large screens, which require a lot of points. Take the outdoor P16 display as an example: there are 3906 dots per square meter, and one dot has three RGB lights, then the power consumption calculation formula for one square meter is 3906 (dots) × 3 (lights) × 0.02 (A) × 5(V)=1172W (maximum power consumption, calculated according to the entire screen), the outdoor screen is at least tens of square meters, or even hundreds of square meters, then the total power consumption is very large. Therefore, reducing the power consumption of the LED display and realizing real energy saving are definitely the most important development direction of the LED display.

Second, develop towards lightness

At present, the most manufactured product in the industry is the iron box screen. The light screen weighs more than 50 kilograms per square meter, plus the weight of the steel structure, and the overall weight is very heavy. Even if it is a small and medium-sized project of tens of square meters, the total weight must be in tons. In this way, many floors of buildings are difficult to withstand such heavy attachments, and the load-bearing balance of the building and the pressure of the foundation are not easy to accept. Therefore, lightness is also the development direction of large LED screens.

Third, develop in the direction of thin and transparent

The commonly used electronic products in our lives, TV sets are becoming thinner and thinner, many mobile phones also use ultra-thin as a product highlight, and computer monitors are also developing in a thinner direction. The product becomes thinner and the weight is correspondingly lighter, which makes it easier to transport and to assemble the display screen. Large LED screens must also keep up with the mainstream of the era of electronic products. Let’s talk about “permeable”. “Permeable” refers to both air and light. If the large LED screen is installed on the top of a high-rise building, then air permeability is very important. The greater the air permeability, the smaller the wind resistance, the stronger the wind resistance, and the greater the protection of the product. If the LED display is installed on the side of a high-rise building, then the product can transmit light and will not affect the indoor lighting. Otherwise, after the product is installed, it will become a dead wall, making the room as dark during the day as at night. In summary, light transmission is also the development direction of large LED screens.

Fourth, develop in the direction of patent protection

From the perspective of global LED patent status, as far as technology is concerned, LED has the characteristics of high technical bottleneck but low entry barrier. The initial investment amount is small and the capital threshold is not high. In order to maintain technological competitiveness and reduce the risk of technological spillover, patents are the best way to protect. The patent barrier is the main means for the first to enter manufacturers to avoid competition. Therefore, patents have become an important issue that cannot be avoided in the development process of the LED industry, but the entire industry has not paid much attention to it. After the start of the LED display industry, there was basically no adjustment and development, and it directly entered a stage of fierce competition. Everyone was busy fighting for the market and expanding the scale, and hardly spent much energy on product research and development, and had not considered knowledge. Property rights are protected, and some new technologies have not been applied for patents in time. As the industry gradually matures, regulates, and protects one’s intellectual property rights and intangible assets by applying for patents is also the inevitable development direction of the LED large screen industry.

Fifth, develop in the direction of fast and accurate splicing

This is mainly for the LED rental display. Lease is characterized by frequent disassembly and assembly to meet temporary needs, so the display cabinets must be able to be spliced ​​quickly and accurately. Just like an outdoor temporary concert, you need to rent a background display of about 50 square meters, and the decision to use a display may be installed two days before the concert. In view of this situation, if the products cannot be spliced ​​quickly and accurately, there will be no way to meet the requirements of the site. Even if it is a fixed installation, this requirement is also required, otherwise it will increase labor costs, affect the flatness of the large screen, and thus affect the display effect. Therefore, fast and accurate installation is also the development direction of LED display.

6.Development towards standardization

At the beginning of this century, huge market demand made large LED screen companies sprung up. Almost overnight, thousands of LED display companies appeared on this magical land in Shenzhen. At the beginning of the establishment of the new enterprise, there will be products to display and sell immediately. Independent research and development of new products has a large investment and a slow speed, so everyone is trying to take shortcuts, sloppy designs, and mutual plagiarism have become a common problem at this stage of the industry. It is not just that the products between companies have different dimensions, mounting holes, etc., even their internal products are also uneven. The mounting fixing plates, hole positions, and screw specifications of the same type of product are not universal. This pair of parts Procurement, material preparation, after-sales service, etc. cause great inconvenience. Therefore, the standardization of LED large-screen products is also an inevitable trend.

How to make the LED display more high-definition

The led display has received widespread attention since its birth. With the continuous advancement of installation technology in recent years, it has been recognized and applied in various industries. The production and maintenance of led displays also require professional knowledge. How to achieve high-definition display?

To achieve high-definition display, there must be four factors: one is that the film source requires full high-definition; the second is that the display needs to support full high-definition; the third is to reduce the dot pitch of the led display; the fourth is the combination of the led display and the video processor. At present, the LED full-color display is also moving towards a higher definition display.

1. Improving the contrast of the LED full-color display. Contrast is one of the key factors that affect the visual effect. Generally speaking, the higher the contrast, the clearer the image and the brighter the color. High contrast is very helpful for image clarity, detail performance, and gray level performance. In some text and video displays with large black-and-white contrast, high-contrast full-color LED displays have advantages in black-and-white contrast, clarity, and integrity. Contrast has a greater impact on the dynamic video display effect. Because the light-dark transition in the dynamic image is faster, the higher the contrast, the easier it is for human eyes to distinguish such a conversion process. In fact, the contrast improvement of LED full-color screen is mainly to increase the brightness of full-color LED display and reduce the reflectivity of the screen surface. However, the brightness is not as high as possible, too high, but it will be counterproductive, not only will affect the LED display Lifespan will also cause light pollution. Light pollution has become a hot topic now, too high brightness will have an impact on the environment and people. Full-color LED display LED panels and LED light-emitting tubes undergo special processing, which can reduce the reflectivity of the LED panel and increase the contrast of the full-color LED display.

2. Increase the gray level of the full-color LED display; the gray level refers to the number of brightness levels that can be distinguished from the darkest to the brightest in the brightness of the single primary color of the full-color LED display. The higher the gray level of the full-color LED display , The richer the color, the brighter the color; on the contrary, the display color is single and the change is simple. The increase of the gray level can greatly increase the color depth, making the display level of the image color increase geometrically. The LED gray scale control level is 10bit~16bit, making the image level resolution details and display effect of high-end display products reach the world’s advanced level. With the development of hardware technology, LED gray scale will continue to develop to higher control accuracy.

3. Reducing the dot pitch of the full-color LED display and reducing the dot pitch of the full-color LED display can improve its clarity. The smaller the dot pitch of the full-color LED display, the more delicate the screen display. However, mature technology must be the core support for this. The input cost is relatively large, and the price of the full-color LED display produced is also high. However, the market is also developing towards small-pitch LED display.

4. The LED full-color display screen is combined with the video processor. The LED video processor can use advanced algorithms to modify signals with poor image quality, and perform a series of processing such as deinterlacing, edge sharpening, motion compensation, etc., to enhance the image The details to improve the picture quality. The image scaling algorithm of the video processor is used to ensure that the sharpness and gray level of the image are maintained to the greatest extent after the video image is scaled. In addition, the video processor is also required to have a wealth of image adjustment options and adjustment effects to process image brightness, contrast, and grayscale to ensure that the screen outputs a soft and clear picture.
