The application of LED display panels has gone deep into our daily life, and now many commercial led video wall shows and public services have their participation. Although the use of LED display screen has been popularized, there are still some problems, such as interference light. How does interference light come about, you know? The following edition gives you an analysis.
First, its own factors: outdoor LED display has the characteristics of high brightness. If the brightness output of the LED display reaches 8000cd/m2 in the dark night, it will cause serious light interference.
2. Viewing position: The closer the distance between the viewer and the LED screen, or the larger the diagonal angle between the viewer’s position and the LED screen, or the more convergent the viewer’s line of sight and the display screen, the more serious interference light will be generated.
Third, the influence of illumination: There is a significant difference between daytime and night ambient illumination, which also causes the same brightness LED display screen in different time periods will produce different degrees of interference light.
Fourth, viewer factors: viewers of different ages, occupations, health status, psychological mood, will feel different degrees of interference light. For example, viewers who are often exposed to photosensitizers or suffer from eye diseases are more sensitive to light.
Play content: If the content of the image displayed on the LED display changes too fast, it will easily cause discomfort to the viewer; if the brightness of the color is too high and the transition is rigid, it will also cause discomfort to the human eye.
