1. Flatness parameter.
For any display device, the flatness of an indoor LED display is crucial, as it directly affects the final display effect. Generally, the flatness is required to be within a 1 mm error margin to ensure that the image is not distorted. If there are protrusions or depressions exceeding this range, the display effect will be very poor.
2. Viewing angle issue.
Everyone knows that when installing an LED display, it's impossible to guarantee that it's perfectly parallel to everyone's line of sight, so there will be a certain viewing angle issue. This requires the indoor display screen to have a certain viewing angle. If the viewing angle is too large, the video display effect will be affected. Therefore, the LED screen needs to have a certain viewing angle in its packaging.
3. Brightness parameter influence.
The good display effect we see is related to the brightness of the LED display. If the brightness of a typical indoor LED display is too low, the display effect may be poor, especially during the day, when the image is basically invisible. Therefore, brightness must be ensured, which is also closely related to the LED chip. If the chip is of poor quality, the brightness cannot be guaranteed. Of course, the brightness should also be within a reasonable range; if it's too bright, it can easily cause light pollution and waste energy.
