Detailed small pitch LED

The small-pitch LED display is one of the most popular keywords in the commercial display market in 2018. Since the small-pitch LED display can display higher-resolution images at the same size, this performance is of great significance for LED display products to become consumer home display devices. The home display device is very meaningful, and it has the characteristics of high color gamut, high refresh rate, no image sticking, low power consumption, etc., which is in line with the trend of the current user demand for the living room screen display effect.

So how is the small-pitch LED display defined? We all know that LED display is made up of LED lamp beads. The distance between LED display screens refers to the distance between the center points of two LED lamp beads. The LED display industry generally adopts the method of defining product specifications according to the distance. For example, our common P12, P10, P8 (point spacing is 12mm, 10mm and 8mm respectively), etc., and as the process progresses, the dot pitch is getting smaller and smaller. According to the industry consensus, LED displays with a dot pitch of less than 3 mm are small-pitch LED displays. It is understood that in the current mass production LED display, the minimum point spacing is P1.6, that is, the distance between the center points of the two lamp beads is only 1.6mm.

Everyone has seen LED display products in their daily life. Whether it is a roadside tobacco and tea shop, or a major hotel building, or a party performance stage, the usage rate of LED display is still quite high, but those traditional large-pitch LED display products are mostly used. With the maturity of small-pitch technology, LED display manufacturers began to look to the broader indoor application market. Have you ever thought about a small pitch LED display in the living room, conferences behind LCD TVs, projectors? 

We introduced earlier that the small-pitch LED display has some advantages that are not available in existing mainstream home display devices, such as high color gamut, high refresh rate, low power consumption, etc., while small-pitch products also have some problems that still not solved. It affects it to become the preferred product for home users or offices.

The first is the price. Due to the need to install more LED lamp beads per unit area, the small-pitch LED display has higher requirements on the process, and the heat dissipation, circuit and other issues have to be solved to cost more than the large-pitch products. The low rate makes the current price of small-pitch LED products still high. For ordinary users, products with more than 100 inches cost hundreds of thousands RMB to purchase, which is quite difficult. On the other hand, with the increase in the capacity of small-pitch LED displays and the advancement of technology, the yield will be further improved and the price of products will continue to fall.

Secondly, it is a space problem. Even for products with small pitches such as P1.6, to achieve full HD resolution (1920×1080), the screen size will reach 144 inches. This is a huge demand for space, not including the base. The length and width specifications are about 3.2 meters x 1.8 meters. It is not easy to find a wall that can put it down. It is not necessary to consider the complicated installation work of this big guy.

Another important issue is maintenance. Although the life of LED lamp beads can reach 100,000 hours, due to the extremely high density and the required thickness of the incoming products, it is difficult to dissipate heat and is prone to local failure. It is not a simple matter to maintain and repair such a giant.

The above points are the main reason why small-pitch LED display products are still difficult to enter the homes of ordinary people. Of course, LED display manufacturers are actively responding to these problems. Aside from these problems, the small-pitch LED display is absolutely no problem in the visual experience. Since there is no display technology of backlight transmission, it is directly illuminated by the lamp bead, so the response time, color capability, brightness, etc. of the LED display indicators have an advantage over LCD products’.

If you look at it now, small-pitch LED display products can only be used in luxury villas, high-end conference rooms and other places. The general consumer group does not have the ability to consume it, but in the future, small-pitch LED display products will replace the projectors and applied in the main conference room instead of the LCD TV, which is worth looking forward to.
