How to define a small pitch LED display

The small pitch LED display is one of the keywords with the highest exposure rate in the commercial display market since 2015. Since the small pitch LED display can display higher resolution images at the same size, this performance is very meaningful for LED display products to become consumer home display devices. It also has the characteristics of high color gamut, high refresh rate, no afterimage, low power consumption, etc., but the price is relatively expensive at present

So how is the small pitch LED display defined? We all know that LED display screens are made up of LED lamp beads. The pitch of 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 P3, P2.5, P2 (that is, the dot pitch is 3mm, 2.5mm and 2mm respectively), etc., and with the advancement of technology, the dot pitch is becoming smaller and smaller. What pitch can be called a small pitch LED display? This is a relative definition, not an absolute definition. For example, in 2016, the pitch below P4 can be called a small pitch LED. In 2017, the pitch below P2.5 can be called a small pitch LED. This year, in 2018, the pitch below P2 can be called a small pitch LED display.

We have seen LED display products in our daily lives. Whether it is a roadside tobacco, alcohol and tea shop, or a major hotel property, or a performance stage, the utilization rate of LED display is still quite high, but those products mostly use traditional large-pitch LED display products. With the maturity of small-pitch technology, LED display manufacturers have begun to look at a broader indoor application market. Have you ever thought about placing a small-pitch LED display in the living room or conference room after LCD TVs and projectors?

We have previously introduced that small-pitch LED displays have some advantages that existing mainstream home display devices do not have, such as high color gamut, high refresh rate, low power consumption, etc., and small-pitch products also have some problems that have not yet been solved by customer service, which affects its further becoming the preferred product for home users or offices. First of all, the price. Since more LED lamp beads need to be installed per unit area, small-pitch LED display screens have higher requirements for craftsmanship, and it costs more to solve problems such as heat dissipation and circuits than large-pitch products. The yield rate is low, resulting in the current high price of small-pitch LED products. For ordinary users, products above 100 inches cost hundreds of thousands of yuan to purchase, which is quite difficult. On the other hand, with the growth of production capacity and technological advancement of small-pitch LED display screens, the yield rate will be further improved, and product prices will continue to fall.

The second is the space problem. Even for small-pitch products such as P1.6led, to achieve full HD resolution (1920×1080), the screen size will reach 144 inches, which is a huge demand for space. The length and width specifications excluding the base are about 3.2 meters × 1.8 meters. It is not easy to find a wall that can put it down, and this is without considering 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 low thickness required for indoor products, it is difficult to dissipate heat and prone to local failures. It is not a simple matter to maintain and repair such a behemoth, and it is not something that everyone can do. It is impossible for non-professional people and professional technicians to do it.
