The application of LED display screens is becoming increasingly widespread and diverse. With the development of technology, LED displays will present the following six major development directions in the future:
1、 Developing towards energy conservation
LED (semiconductor light-emitting diode) itself is very energy-efficient, with characteristics such as high luminous efficiency, long lifespan, easy control, and maintenance free; It is a new generation of solid-state cold light source, with soft, bright, colorful, low loss, low energy consumption, and is a green and environmentally friendly product. But when made into an LED display screen, the power consumption is not small. The working voltage of LED is generally 3.2V, and the maximum working current is 0.02A, which means the maximum power consumption is 0.06W. However, LED screens are all large screens that require many dots to form. Taking the outdoor P16 display screen as an example: there are 3906 points per square meter, and each point has three RGB lights. The power consumption calculation formula for one square meter is 3906 (points) × 3 (lights) × 0.02 (A) × 5 (V)=1172W (maximum power consumption, calculated based on the entire screen). Outdoor screens are at least tens of square meters, or even hundreds of square meters, so the total power consumption is very high. So reducing the power consumption of LED displays and achieving true energy conservation is definitely the most important development direction for LED displays.
2、 Developing towards lightweight direction
The most commonly produced product in the industry currently is the iron box screen, which weighs over 50 kilograms per square meter for the light screen body, and when combined with the weight of the steel structure, the overall weight is very heavy. Even for a small to medium-sized project of several tens of square meters, the total weight must be measured in tons. In this way, many high-rise buildings are unable to withstand such heavy attachments, and the balance of the building's load-bearing capacity and the pressure on the foundation are not easily accepted. So, lightweight is also the development direction of LED large screens.
3、 Developing towards thin and transparent direction
The electronic products commonly used in our daily lives, such as televisions, are becoming thinner and thinner, many mobile phones are also highlighting ultra-thin features, and computer monitors are also developing towards thinness. The product becomes thinner and lighter in weight, making it easier to transport and assemble for display screens. LED screens must also keep up with the mainstream of electronic products. Speaking of "transparency", "transparency" refers to air and light transmission. If LED screens are installed at the top of high-rise buildings, then air transmission is very important. The higher the ventilation rate, the lower the wind resistance, the stronger the wind resistance, and the greater the protection for the product. If the LED display screen is installed on the side of a high-rise building, the product can transmit light and will not affect indoor lighting. Otherwise, after the product is installed, it will become a dead wall, making the room dark during the day as well as at night. In summary, thin and delicate screens are also the development direction of LED large screens.
4、 Developing towards patent protection
From the current status of global LED patents, in terms of technology, LED has the characteristics of high technological bottlenecks but low entry barriers. The initial investment amount is not large, and the capital threshold is not high. In order to maintain technological competitiveness and reduce the risk of technology spillover, patents are the best way to protect. The patent barrier is the main means for early entrants to avoid competition, so patents have become an important issue that cannot be avoided in the development process of the LED industry. However, the entire industry has not paid much attention to it at present. After the LED display industry started, it basically did not experience adjustment and development, and entered a stage of fierce competition directly. Everyone was busy competing for the market, expanding scale, and almost did not spend much energy on product research and development. It also did not take into account intellectual property protection, and some new technologies did not apply for patents in a timely manner. As the industry gradually matures and standardizes, protecting one's intellectual property and intangible assets through patent applications is also an inevitable development direction for the LED large screen industry.
5、 Developing towards fast and precise splicing direction
This is mainly for LED rental display screens. The characteristic of leasing is frequent disassembly and assembly to meet temporary needs, so the display screen boxes must be able to be quickly and accurately spliced together. Just like a temporary outdoor concert, you need to rent a background display screen of about 50 square meters, and the decision to use the display screen may be made two days before the concert starts. In this situation, if the product cannot be quickly and accurately assembled, it cannot meet the on-site requirements. Even if it is a fixed installation, this requirement still exists, otherwise it will increase labor costs, affect the flatness of the large screen, and thus affect the display effect. So fast and precise installation is inevitably the development direction of LED display screens.
6、 Developing towards standardization
At the beginning of this century, the huge market demand led to the emergence of LED display companies like mushrooms after rain. 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 should be products to showcase and sell. The investment in independent research and development of new products is large, but the speed is slow, so everyone is trying to take shortcuts, hastily design, and copy each other, which has become a common problem in this stage of the industry. Not only do products between enterprises have different external dimensions, installation hole positions, etc., but even their internal products are uneven. The installation fixing plates, hole positions, and screw specifications of the same type of product do not need to be universal, which causes great inconvenience to parts procurement, material preparation, after-sales service, etc.
