As a new industry in the new era, LED display screens, government departments and industry experts have explained the development direction and trends of the LED display screen industry, and almost no systematic description of the development direction of LED display screen products. As an R & D and production enterprise in the LED industry, Lianchengfa has been thinking deeply about this issue. New products must have R & D direction before designing products. The R & D personnel of Lianchengfa should have a deep understanding of LED display products and a keen insight into the industry market. The end-use customer's problem response and the practicality of project site construction will directly guide the development direction of the product; enterprises should realize the coexistence of market demand orientation and R & D orientation, and design new products that are more suitable for project use. Based on these considerations, Lianchengfa has the following views on the development direction of new products.
1. Development towards energy saving
LED (Semiconductor Light Emitting Diode) itself is very energy-saving, and its characteristics are: high light efficiency, long life, easy control, and maintenance-free; it is a new generation of solid cold light source, soft light, gorgeous, colorful, low loss , Low energy consumption, is a green product. But the power consumption is not small when made into LED display screen. The working voltage of LED is generally 3.2V, and the maximum working current is 0.02A, which means that the maximum power consumption is 0.06W. However, LED display screens are large screens and require many points. Take the outdoor P16 display as an example: there are 3906 dots per square meter, and three RGB lights in one dot, then the formula for calculating power consumption per square meter is 3906 (dots) × 3 (lamps) × 0.02 (A) × 5 (V) = 1172W (maximum power consumption, calculated on the whole screen), outdoor screens are at least tens of square meters, or even hundreds of square meters, then this total power consumption is very large. Therefore, reducing the power consumption of LED display screens and realizing real energy saving is definitely the most important development direction of LED display screens.
2. Development towards lightness
The most popular product in the previous industry is the iron box screen. The weight of the light screen body is more than 50 kg per square meter. Adding the weight of the steel structure, the whole is very heavy. Even if you do a small and medium-sized project of tens of square meters, the total weight should be in tons. In this way, many floors of buildings are difficult to withstand such heavy attachments, and the building's load-bearing balance and foundation pressure are not acceptable. Therefore, lightweight is also the development direction of LED display.
3. Development towards thin penetration
The electronic products commonly used in our lives, TV sets have become thinner and thinner, many mobile phones also use ultra-thin as the product highlight, and computer monitors are also developing in the direction of thinness. The product becomes thinner and the weight is correspondingly lighter, which is more convenient for transportation and assembly for the display screen. LED display production must also closely follow the mainstream of the era of electronic products. Let's talk about "through", "through" refers to ventilation and light transmission. If the large LED screen is installed on the top of a high-rise building, then ventilation is very important. The greater the ventilation rate, 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, the product can transmit light, and it will not affect the indoor lighting. Otherwise, after the product is installed, it will become a dead wall, so that the room will be dark during the day and night. In summary, thin and compact is also the development direction of LED display.
4. Development 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 bottlenecks but low entry barriers. The initial investment is not large, and the capital threshold is not high. In order to maintain technological competitiveness and reduce the risk of technological spillovers, patents are the best way to protect. The patent barrier is the main means for manufacturers to enter the market to avoid competition. Therefore, patents have become an important issue that cannot be avoided in the development process of the LED industry, but at present, the entire industry has not paid much attention to it. After the LED display industry started, it basically entered the stage of fierce competition without undergoing adjustment and development. Everyone was busy fighting for the market and expanding the scale. They did not spend much energy on product development and did not take into account knowledge. For the protection of property rights, some new technologies have not been applied for in time for patent maintenance. As the industry gradually matures, regulates, and protects its intellectual property rights and intangible assets through patent applications, it is also the inevitable development direction of the LED display industry.
V. Development in the direction of rapid and precise splicing
This is mainly for LED rental display. The characteristic of leasing is that it is often disassembled and assembled to meet temporary needs, so the display boxes 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 the display may be installed two days before the concert. In view of this situation, if the products cannot be spliced ​​quickly and accurately, there is no way to meet the requirements of the scene. Even if it is 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 bound to be the development direction of LED display.
6. Development towards standardization
At the beginning of this century, the huge market demanded that LED display companies spring up. Almost overnight, thousands of LED display companies appeared on this magical land of Shenzhen. At the beginning of the establishment of a new enterprise, there are products to be displayed and sold. Independent research and development of new products has a large investment and a slow speed, so everyone is looking for a shortcut, sloppy design, and mutual plagiarism has become a common problem in this stage of the industry. It is not only that the products have different dimensions, installation holes, etc., but also their own internal products are uneven. The installation fixing plates, holes, and screw specifications of the same type of products are not common. This pair of parts Procurement, material preparation, and after-sales service all cause great inconvenience. Therefore, the standardization of LED display products is also an inevitable trend.
In the modern information society, display products and technologies as visual communication media for human-machine information have been rapidly developed. The display technology in the 21st century will be the era of flat panel displays. As one of the leading products of flat panel display, LED display screen will undoubtedly have more room for development, and may become the representative mainstream product of flat panel display in the 21st century. Lianchengfa R & D team keeps up with the pulse of the times, meets the actual needs of customers, controls the direction of product development, and gives new products more advantages, truly making LED display practical and easy to use.
