It is not recommended to use large-pitch specifications for small-area screens, but it is possible to use small-pitch specifications for large-area screens. For example, for a full-color LED display of about 10 square meters, it is recommended to use P2 or P2.5 instead of P4 or P5; for LED displays of 50 square meters or more, P3, P4, P5, P6, P7.62 are available, If the budget is sufficient, the effect of choosing P2.5 is of course clear, but it is more economical to choose models above P3.

　　 At present, Chenzhi Technology indoor LED full-color display sales are better:

　　P2 full-color display has a pixel density of 250,000 dots/square meter. Our standard module size is 256mm*128mm. Naturally, its high definition does not need to be said, but the production cost is relatively high, when the area of the LED display screen is more than 3 square meters.

The P3 full-color LED display has a physical pixel density of 111111 dots/square meter, and the standard module size is 192*192mm. It adopts 1/32 constant current dynamic scanning mode. The brightness can reach more than 1800cd/㎡, which is enough to meet the needs of indoor brightness display. display. The screen area is more than 8 square meters.

　　The physical pixel density of P2.5 display is 160,000 dots/square meter. The standard size of our module is 320*160mm. The best viewing distance is 2.5 meters or more, and the screen area is more than 10 square meters.

The advantages of led screen and the introduction of classification

LED display (LED display): a flat panel display, composed of small LED module panels.

　　 LED, light emitting diode (abbreviation of light emitting diode). It is a diode made by compound of gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), and indium (In) by controlling the display mode of semiconductor light-emitting diodes. It can radiate visible light when recombined, so it can be used to make light-emitting diodes. Used as indicator light in circuits and instruments, or composed of text or digital display. Phosphor gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and indium gallium nitride diodes emit blue light.

　　 LED display is generally used to display various information such as text, image, video, video signal and so on.
