How to identify the brightness level of roll-up LED display?

  For roll-up LED display, the more grades the human eye recognizes, the better, naturally, because the displayed image is, after all, for people to see. The more luminance levels the human eye can distinguish means the larger the color space of the roll-up LED display, and the greater the potential for displaying rich colors. So you knowRoll-up LED DisplayHow to identify the brightness level? The following Vishay Technology editorial is for you:

  Luminance discrimination level refers to the brightness level between black and white of an image that the human eye can distinguish. As mentioned earlier, some of the gray levels of the display are very high and can reach 256 or even 1024 levels. However, due to the limited sensitivity of the human eye to brightness, and can not fully recognize these gray levels. That is to say, there may be many adjacent levels of gray scale human eyes look the same. Moreover, the eye's ability to recognize these levels varies from person to person.

  For the brightness of the roll-up LED display to identify the level, we in general, you can use special software to test, general display can reach more than 20 levels even if it is a better grade.

  The higher the grayscale level of the roll-up LED display, the richer the color, the more colorful; on the contrary, the display color is single, simple changes. Of course, the higher the gray level of the roll-up LED display, the corresponding increase in cost. When the gray level of the display exceeds the human eye perception limit, the roll-up LED display cost-effective is down. Therefore, when we choose the gray level parameter of roll-up LED display, combine the playback effect and cost, choose the one that suits you.

  To summarize, it is the way to identify the brightness level of the roll-up LED display. Determining the brightness of the roll-up LED display is a very necessary thing, because in the city there are regulations on the brightness requirements of the roll-up LED display, otherwise, the roll-up LED display is too bright, which will cause a nuisance to the nearby residents. Therefore, in order to avoid adverse repercussions, this requires businessmen to have relevant expertise in customizing and maintaining roll-up LED displays.
