P is the distance between the center points of two lamps (generally representing the pixel spacing), and the value after P is the distance between two pixel points, commonly known as the point spacing. The smaller the distance between two pixels, the higher the unit pixel and the clearer the display screen. Just like P6, this means that the distance between the center points of two lamps is 6mm. Usually, the lower the dot spacing, the higher the pixel of the display screen, and the clearer and more expensive it is.
In order to improve brightness and increase sight distance, one pixel of outdoor led display screen contains more than two cluster LEDs. The pixel diameter of outdoor display screen is generally expressed by the average distance between two pixels, namely, P 10, P 1 1.5, P 16, P22 and P25. Small-pitch LED displays mainly include LED display products such as P2.5, P2.0, P 1.8, P 1.5, and refer to indoor LED displays with LED dot spacing below P2.5. ..
operating characteristic
(1) High-intensity luminescence, under the refraction of solar light, the content on the screen surface can be presented in high definition within the visual range. ?
(2) The gray control level is high. You can use the gray scale control of 1024 ~ 4096 to clearly and realistically display the colors above 16.7M to ensure the super stereoscopic effect of the picture.
(3) The driving power is high, and the scanning mode is mainly static latching to ensure high-intensity light. ?
(4) In order to ensure the best playback effect, the brightness can be reasonably controlled through the automatic adjustment function in different background environments. ?
(5) Circuit integration mainly depends on large-scale imported devices, which improves the reliability of operation and is conducive to maintenance and debugging. ?
(6) Using modern digital processing technology to process the video, and mainly selecting the way of technology allocation to scan, designing modularity, static constant current driving, and automatic brightness adjustment, so as to realize high fidelity and no ghosting, and improve the image clarity. ?
(7) There are various information displays, such as icons, videos, characters, animations, pictures, etc. , and various realistic forms, such as networking, remote reality, etc. , and the combination of common colors and techniques.
