What is small pixel pitch led display?

The small-pitch LED display is one of the keywords with the highest exposure in the commercial display market since 2014. Since the small-pitch LED display can achieve higher resolution pictures at the same size, this performance has become a consumer for LED display products. Home display equipment is very meaningful, and it has both high color gamut, high refresh rate, no after image, low power consumption and other characteristics, which is in line with the current trend of users' requirements for living room screen display effects.

So how is a small-pitch LED display defined? We all know that LED display screens are composed 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 based on the size of this distance. , Such as our common P12, P10, P8 (point pitch is 12mm, 10mm, and 8mm respectively) and so on, and with the progress of technology, the point pitch is becoming smaller and smaller. According to the general consensus in the industry, LED displays with dot pitch below 3mm are small-pitch LED displays. It is understood that in the current mass-produced LED display, the smallest dot pitch is the P1.6 specification, that is, the distance between the center points of the two lamp beads is only 1.2mm.

Everyone has seen LED display products in daily life. Whether it is a tobacco, tea and tea shop on the roadside, or a major hotel building, or a performance stage at a party, the use rate of LED display is still quite high, but those products are mostly used. Traditional large-pitch LED display products. With the maturity of small-pitch technology, LED display manufacturers have begun to focus on a wider indoor application market. Have you ever thought about LCD TVs, projectors, living rooms, conferences, etc? Is there a small-pitch LED display indoors?

We introduced earlier that the small-pitch LED display has some advantages that the current mainstream home display devices do not have, such as high color gamut, high refresh rate, low power consumption, etc., and the small-pitch product also has some problems that currently have no customer service. Affecting it to further become the product of choice for home users or offices.

The first is the price. Due to the need to install more LED lamp beads per unit area, small-pitch LED displays have higher process requirements, and issues such as heat dissipation and circuits need to be solved at a higher cost than large-pitch products. The low rate has caused the current price of small-pitch LED products to remain high. For ordinary users, products of 100 inches or more will cost hundreds of thousands of yuan to buy, which is quite difficult. On the other hand, as the production capacity of small-pitch LED displays increases, technology advances, the yield rate will be further improved, and product prices will continue to fall.

The second problem is the space. Even for products with small pitches such as the P1.6 specification, to achieve full HD resolution (1920 × 1080), the screen size will reach 144 inches. This is a huge demand for space. The length and width specifications are about 3.2 meters by 1.8 meters. Finding a wall that can put it down is not an easy task. 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, it is difficult to dissipate heat and cause local failures due to the extremely high density and low thickness of the products required to enter the room. It is not a simple matter to maintain and overhaul such a behemoth.

The above points are the main reasons why it is still difficult for small-pitch LED display products to enter ordinary people's homes. Of course, for these problems, LED display manufacturers are actively responding. Aside from these problems, the small-pitch LED display is absolutely no problem in the visual experience. Since there is no display technology link of backlight transmission, it is directly displayed by the lamp beads, so the response time, color capabilities, brightness of the LED display The indicators are more advantageous than LCD products.

If you look at it now, small-pitch LED display products can only be used in rooms such as luxury villas and high-end conference rooms. The average consumer population does not have the ability to consume it. The main conference room, replacing the LCD TV into the main living room, is worth looking forward to.
