After decades of rapid development, the development of LED electronic display industry in China has been rapid to slow, although the LED display market is almost saturated in the past two years, but compared with other industries, LED screen is still in the ranks of rapid development. . It is also because of the rapid development, which has caused some unavoidable problems in this market.
Let's analyze what are the problems with these current LED displays?
Question 1: Whether it is a street or a highway, the LED display can be seen everywhere. These dazzling colors not only bring us enjoyment, but bring some negative effects. The bright screen is not only dazzling during the day, but also affects the rest of the public at night, and distracts the driver's attention and breaks the focus of driving.
Solution: The relevant management department has adopted a method to limit the lighting time and brightness. The LED display manufacturer adopts the automatic brightness adjustment function, which adjusts itself according to the brightness of the environment, which not only can save energy, but also harms the people. Can be overcome.
Question 2: LED display security issues, fire accidents caused by LED display fires almost every year, perhaps some fires are not caused by the led display itself, but the pool fish, but the security of the led display still has to be on the agenda. The led display is composed of a large number of modules. The larger the area of ​​the display, the more modules, the greater the power, the more prominent the heat dissipation problem, the more hidden dangers caused by power consumption.
Solution: (1) The safety and stability of the wire can be ensured by using the wire that meets the requirements of the national standard. The wire core is the copper wire conductive carrier, the wire core cross-sectional area tolerance is within the standard range value, the insulation of the rubber core of the wrapped wire core and the flame retardancy. To reach the standard, compared with the general copper-clad aluminum wire core, the wire core cross-sectional area is small, and the insulation rubber grade is not enough, the electric current performance is more stable, and the short circuit condition is not easy to occur;
(2) The power products that pass UL certification are also the best choice when selecting similar products. The effective conversion rate can ensure the safety and stability of the power supply load, and it can work normally even under the hot environment of external environment;
(3) In the material of the outer protective structure of the display screen, the fireproof aluminum-plastic composite board is used, which has excellent fire resistance, strong fireproof and flame retardancy, and strong oxygen aging performance of the core material.
(4) The plastic kit is mainly used for the bottom cover of the unit module mask, and the raw material is PC+ glass fiber material with flame retardant function;
(5) In the case where the core raw materials such as lamp beads are not broken, the brightness cannot be increased by increasing the current;
(6) Correct installation.
Question 3: LED display price problem, the price of a consumer accounted for more than 50% of the purchase intention. In addition to small-pitch products, the price of LED displays has almost stabilized, and with the development of technology, prices have been decreasing year by year. In the past two years, small-pitch products have spread widely among users. The outstanding advantages of small-pitch LED displays have been recognized by many consumers in an instant, but the price of small-pitch products caused by the use of more chips may be small-pitch applications. Promoted a "roadblock".
Solution: At present, some LED display manufacturers have successfully achieved 0.7mm, but the real application? Even the application of 1.2mm small pitch products is one of the few. From the viewing effect and cost control, the small pitch of 1.0mm or even 1.2mm can fully meet the needs of viewing. In addition, the price of 1.2mm small pitch products has been difficult for consumers to accept. For LED display manufacturers, the most important thing at present is not to develop LED screens with smaller spacing, but how to put existing technologies into practical use. In order for users to accept their own products, we must first face the price/performance ratio. If the price cannot be accepted by consumers, the product can only be used for pure display. The price and performance of the product should be considered comprehensively. Only if the product has sufficient value, the price to the consumer will not be avoided.
In short, the development of an industry is inseparable from the existence of problems, the main thing is to be able to solve the problem, the LED display industry has also developed various problems in the development, but they have been solved by the manufacturers one by one, and have been recognized by users. The development of LED display is actually a process of finding and solving problems. Nowadays, the biggest challenge for LED display manufacturers is small spacing. The infinite opportunities also bring many problems. Who can solve more problems for users, who can get the support of users.
