March 11, 2023

　　 LED display applications have penetrated into our daily lives, and many of them are now involved in commercial presentations and public services. Although the use of LED display screens has become popular, there are still some problems, such as interference light. How does the interference light come about ? Do you know ? The following small series gives you analysis and analysis.

LED

First, its own factors: outdoor LED display has the characteristics of high brightness, if the brightness of the LED display in the dark night reaches 8000cd/m2 , it will cause serious light interference.

Second, the viewing position: the closer the distance between the viewer and the LED display , or the larger the opposite angle formed by the station position and the LED display , or the more the viewer's line of sight and display orientation, the more serious Interference light.

Third, the illumination effect: There is a significant difference in the ambient illumination between daytime and nighttime, which causes the same brightness LED display to produce different levels of interference light in different time periods.

Fourth, the viewer factor: the viewer's age group, occupation, health status, psychological mood is different, will feel different levels of interference light. For example, viewers who are exposed to photosensitizers or suffer from eye diseases are more sensitive to light.

V. Playback content: If the image content displayed on the LED display changes too fast, it will easily cause discomfort to the viewer ; if the color brightness is too high and the transition is hard, it will cause eye discomfort.

Sixth, evaluation criteria: LED display screens are used in many places, such as road traffic, commercial areas, residential areas, etc., due to the nature of the place, the evaluation criteria of the interference light are also different.

VII. Environmental conditions: Environmental conditions will have a significant impact on the LED display interference light. If the environmental conditions are relatively harsh, such as fog, dust, fog, heavy rain, squally weather, etc., it will affect people's interference on the LED display. The judgment of light, under the influence of external factors, will cause the standard of judgment to be inaccurate and affect the objectivity of evaluation.
