How to effectively adjust the brightness of small pitch LED display screens.indoor rental led display wholesale

　　How to effectively adjust the brightness of small pitch LED displays? Firstly, let's refer to the brightness range of various indoor display products in indoor application environments. The brightness range of daily household televisions is 350 cd/㎡ -500 cd/㎡; The brightness range of DLP splicing wall is 250 cd/㎡ -400 cd/㎡; The brightness range of the LCD splicing wall is 450 cd/㎡ -700 cd/㎡.

　　Due to the relative perception of brightness by the human eye, displays using different lighting technologies will also provide different brightness perception to the human eye. After professional equipment testing, everyone believes that the brightness range of LED displays is controlled between 100 cd/㎡ and 300 cd/㎡, so in this brightness range, the human eye feels relatively comfortable.

　　So can we solve this problem by directly adjusting the brightness of the display screen? The answer is not so simple either. Because conventional LED displays have the characteristic of low brightness and low gray, which means that the decrease in display brightness will also be accompanied by a loss of grayscale in the image.

　　If a small pitch LED display screen with a nominal brightness greater than 1200 cd/㎡ is directly applied to our indoor environment, the results will only be two: either high brightness will damage users' eyes, or low brightness will lose both grayscale and image quality, neither of which is what users want.

　　To solve this problem, we need to request our display screen manufacturers to upgrade their current small pitch display products and develop "low brightness and high gray" small pitch LED displays. The so-called low brightness and high gray, its specific explanation is that if the brightness range of small pitch LED displays is between 100 cd/㎡ and 300 cd/㎡, the grayscale of the display screen image does not lose, or the degree of grayscale loss is within the visual range that is difficult to detect by the human eye.

　　Therefore, low brightness and high gray are a threshold that LED display screen manufacturers must cross when entering indoor display applications. Low brightness and high gray will also be one of the key factors distinguishing the high quality of small pitch LED display screens. With the rapid development of LED displays in the industry, small pitch LED displays have developed towards intelligence, ultra-thin, lightweight, and networking. As their technology matures, small pitch LED displays with easy assembly and high performance have been widely used in the market.
