What is a small-pitch LED display? How is the small-pitch LED display defined? I believe that many people know that LED displays are made of LED lamp beads. Many people may not know that the spacing of LED displays is composed of the distance between the center points of two LED lamp beads. The industry of LED displays generally It is to use the size of this distance and the method of defining product specifications, such as our common P10, P8, P6 (point pitch is 10mm, 8mm and 6mm respectively) and so on... And with the advancement of industry technology, The dot pitch of small-pitch LED displays is becoming smaller and smaller. An LED display with a dot pitch of less than 3mm is a small-pitch LED display. According to the evidence collected so far, the smallest distance between the dots is the P1.4 specification, that is, the distance between the center points of the two lamp beads is only 1.4mm.


Many friends have seen LED products in their daily lives, whether it is a tobacco, alcohol and tea shop on the roadside, a major hotel, or a performance stage at a party, the usage rate of LED displays is still very wide, but those Products generally use traditional large-pitch LED displays. In today's society, as the small-pitch technology becomes more and more mature, LED display manufacturers have begun to focus on the broader indoor application market. After the machine, is there a small-pitch LED display in the living room, conference room, etc.?

We all knew from the beginning that the small-pitch LED display has some advantages that the existing mainstream home display devices do not have, such as some high color gamut, high refresh rate, low power consumption, etc... But the small-pitch display The product also has some unresolved problems, which affects it further becoming the favorite of home users or offices.


There are several problems to solve these problems. The first is the price. Since many companies have to install more LED lamp beads, small-pitch LED displays also have high technological requirements. If heat dissipation and circuit problems have to be solved, it will also cost a lot of costs. Now, the low yield rate is a big problem that causes the price of current small-pitch LED products. For some ordinary families now, the small-pitch products of more than 100 inches cost hundreds of thousands of yuan to buy, which is just a lot of ordinary What the family cannot afford. Another aspect is that as the production capacity of small-pitch LED displays increases, the yield rate of some advanced technology will be further improved, and product prices will continue to fall.


There is also a space issue. Even for products with small pitch such as P1.4 specifications, to achieve full HD resolution (1920×1080), the screen size will also reach 140 inches, which is a very large demand for space. The length and width specifications that do not include the base are about three meters x nearly two meters. It is not easy to find a place to put it down.


The third important issue to be mentioned is maintenance. Although the life of LED lamp beads can reach more than 100,000 hours, it is difficult to dissipate heat due to its extremely high density and low thickness of the products entering the room. , Prone to partial failure. It is not a simple matter to maintain and overhaul such a behemoth. The manpower and material resources it consumes are immeasurable. The above three points are the main reasons why it is difficult for the current small-pitch LED screen rental products to enter the homes of ordinary people. However, LED display manufacturers have been working hard to solve these three problems. If you put aside these problems, the visual experience of the small-pitch LED display is no problem, and the effect is still good in the branch. Since there is no display technology link of backlight transmission, it is directly displayed by the lamp beads, so the response of the LED display Indexes such as time, color capability, and brightness are more advantageous than LCD products.
