Small pixel pitch led video wall

Description

With the development of technology and economy, the small pixel pitch be widely used in many applications.

But what is best small pixel pitch led screen and how to choose it? Some tips for your reference as followings:

 

1. High gray scale under low brightness.

As a display terminal, a small-pitch LED screen must first ensure the comfort of viewing. Therefore, 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 100 cd/m2 and 300 cd/m2.

 However, 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. Therefore, 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".

Compared with traditional LED screens, the prominent feature of small-pitch LED screens is smaller dot pitch. In practical applications, the dot pitch is smaller,the physical density is more higher,and the more information capacity that can be displayed per unit area at a time, 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. However, 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. For example, the best viewing distance of P2 small-pitch LED screen is about 6 meters.

 We know that the pixel pitch is more smaller and the cost is higher. Therefore, when you purchase the led screen, you should consider its cost, demand, 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. In practice, the user wants to build an optimal small-pitch LED display system. While paying attention to the resolution of the screen itself, it should also consider its combination with the front-end signal transmission products.

 For example, in security monitoring applications, front-end monitoring systems generally include video signals in formats such as D1, H.264, 720P, 1080I, and 1080P. However, 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.

 At present, 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, airports, railway stations, hotels, and large Medium-sized enterprises and etc.
