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.
