1. The surface flatness of LED display screen should be within + / - 1mm to ensure that the display image does not distort. Local convex or concave will cause dead Angle in the visual Angle of the display screen.Flatness is mainly determined by the production process.
2. The brightness and visual Angle of the indoor full-color screen should be above 800cd/m2, and the brightness of the outdoor full-color screen should be above 1500cd/m2 to ensure the normal operation of the display screen. Otherwise, the image displayed cannot be clearly seen due to the low brightness.The brightness is mainly determined by the quality of LED core.
The size of the viewing Angle directly determines the size of the display audience, so bigger is better.The size of the visual Angle is mainly determined by the way the core is encapsulated.
3. White balance effect white balance effect is one of the most important indicators of the display screen.When the proportion of the red, green and blue primary colors is 1:4.6:0.16, it will show the pure white. If the actual proportion has a little deviation, it will show the deviation of the white balance.The quality of white balance is mainly determined by the control system of the display screen.
