Features of small pixel pitch LED display solution

1. High gray scale under low brightness.

As a display terminal, a small-pitch LED screen must first ensure the comfort of viewing. Поэтому, when purchasing, the primary concern is the brightness problem. Related research shows that from the perspective of human eye sensitivity, LED is an active light source, its brightness is twice that of passive light source (projector and liquid crystal display), and to ensure the comfort of human eyes, small-pitch LED screen The brightness range can only be between 500 cd/m2 and 800 кд/м2.

Однако, in the traditional LED display technology, reducing the brightness of the screen will cause loss of gray scale, and the loss of gray scale will directly affect the picture quality. Поэтому, an important criterion for the high-quality small-pitch LED screen is to achieve “low” Bright and high gray technical indicators, in the actual purchase, the user can follow the principle that “the more the brightness level can be recognized by the human eye, the better.” The brightness level refers to the brightness level of the image that can be distinguished by the human eye from the darkest to the whitest. The more the brightness level is recognized, the larger the color gamut space of the display, and the greater the potential for displaying rich colors.

2. Select the pixel pitch, pay attention to the balance of “effects and technology”.

По сравнению с традиционными светодиодными экранами, Отличительной особенностью светодиодных экранов с малым шагом является меньший шаг точек.. В практических приложениях, шаг точки меньше,физическая плотность более высокая,и тем большую информационную емкость можно отобразить на единицу площади за раз., he best viewing distance is more closer,on the contrary, the farther the distance is suitable for viewing(t).Many users naturally think that purchase the smaller dot pitch led screen is the better. Однако, it is not.

Conventional LED screens want to achieve the best visual effects, with the best viewing line of sight, as well as small-pitch LED screens. The user can make simple calculations by the best visual distance=point spacing/0.3~0.8. Например, the best viewing distance of P2 small-pitch LED screen is about 6 метры.

We know that the pixel pitch is more smaller and the cost is higher. Поэтому, when you purchase the led screen, you should consider its cost, требовать, application range and other factors.

3. Select the resolution, pay attention to the “front-end signal transmission equipment”.

The smaller the dot pitch of the small-pitch LED screen, the resolution is higher, and the sharpness of the picture is higher. На практике, the user wants to build an optimal small-pitch LED display system. При этом обращайте внимание на разрешение самого экрана, it should also consider its combination with the front-end signal transmission products.

Например, in security monitoring applications, front-end monitoring systems generally include video signals in formats such as D1, H.264, 720P, 1080I, and 1080P. Однако, not all small-pitch LED screens on the market can support the above. The video signal of the format, therefore, in order to avoid the waste of resources, the user must select the on-demand when purchasing the small-pitch LED screen, and should not blindly catch up with the trend.

В настоящий момент, small-pitch LED products have been widely used in TV studios, power system monitoring centers, space command centers, force command centers, government administration halls, city monitoring centers, video conference rooms, аэропорты, Железнодорожные станции, отели, and large Medium-sized enterprises and etc.
