Small space LED display features - Shenzhen caishida, touch screen and OLED Forum
It's different from the past advocating "big is beautiful". In the past two years, most of the exhibitors have presented their visual experience with clear, delicate and close-up display screen in front of the masses; Stalls are no longer just display areas for display products, but are integrated into user situations, such as conference rooms, central control systems, banquet halls, etc., making it easier for buyers and audiences to feel the terminal applications of display screens; The structural design of the display screen for specific application makes the display screen become a part of our life experience. LED TV and LED display advertising machine are the focus of the exhibition.

looking at many exhibitions at present, most of the exhibitors in the past two years are clear, delicate and beautiful The display screen visual experience of close viewing is presented in front of the masses; Stalls are no longer just display areas for display products, but are integrated into user situations, such as conference rooms, central control systems, banquet halls, etc., making it easier for buyers and audiences to feel the terminal applications of display screens; With the required structural design of the display screen for specific applications, the display screen will become a part of our life experience, such as LED TV, LED display advertising machine, All of them are the focus of the exhibition.

Features of small dot spacing LED display screen - Shenzhen caishida

generally speaking, displays with pitch less than 4 mm are called small pitch displays.
generally, displays with pitch less than 2.5 mm can be called ultra dense screens.
in the following content.
P2 means that the pitch is 2 mm, p2.5 means that the pitch is 2.5 mm, And so on.
in terms of the market scene.
small space display screen is absolutely the focus of all display screen manufacturers.
p3.9 display screen is used to watch products with a distance of about 2-3 meters.
p3.9 display screen is used to watch products with a distance of about 2-3 metersFor example, the vertical advertising machine that can be placed on the ground is used to replace the traditional advertising light box or window display. Its advantages are bright color, clear picture and enough brightness; P2.5 display screen can be said to be a star product in the small space classification, mainly because p2.5 can basically meet the needs of users in indoor, viewing distance of 1-2 meters, but in the refresh rate, color performance (gray scale), contrast and low gray details, the products of various manufacturers are different; The leading manufacturers in the research and development of small dot spacing products also exposed their products below P2 in Guangzhou Exhibition. Various specifications such as p1.9/p1.8/p1.6/1.4/p1.2/p1.0 are gathered together, which is very wonderful.
however, they are similar to p2.5 products.
in terms of refresh rate, gray scale and low gray scale performance, they can still compare with the products of various manufacturers.
in fact.
the display quality of the display screen, It has always been closely related to the driver chip, especially in the small dot spacing display.
why does the driver chip affect the display quality so much? The reason lies in the "multi line scan design"
the small dot spacing display screen is in the same unit area.
it must accommodate more components of the large dot spacing display screen, and more LED light points must be placed on the front of the lamp board. Take p2.5, lamp driver as an example: there are 160000 SMD LED light points in 1 square meter lamp board area; The back of the lamp board needs to be equipped with driver chip, current setting resistor and other components. If the static screen is used, 30000 16 channel driver chips and 30000 current setting resistors are needed. Considering the cost of wiring and increasing the number of PCB layers, it is necessary to design a multi line scan.
the multi line scan design allows more LED lights to be lit by one driver chip.
the design of multi line scan allows more LED lights to be lit by one driver chipThe smaller the distance between dots, the higher the number of rows will be used.
generally speaking.
the p2.5 display screen will adopt the 16 scan design, and the display screen with the distance between dots less than 2mm will adopt the design higher than the 16 scan design.
