1. Check the white balance of the conference room LED display screen.
The quality of the white balance is determined by the display screen's control system, so pay attention to whether the white color has a deep blue or yellowish-green tint.
2. How is the flatness of the conference room LED display screen?
The flatness of the LED display screen should be within ±1mm, which reflects the manufacturer's attention to detail and manufacturing process. If the display screen's flatness is poor, it will lead to blind spots in the viewing angle.
3. Color reproduction
The colors displayed on the conference room LED display screen should be highly consistent with the colors of the playback source to ensure the realism of the image.
4. Check for color blocks
Color blocks refer to noticeable color differences between adjacent modules, where the color transition occurs in units of modules. This phenomenon is mainly caused by a poor control system, low grayscale levels, and low scanning frequency.
5. Are there any mosaics or dead pixels?
Mosaics refer to small, constantly lit or dark squares appearing on the display screen, indicating module failure. The main reason is that the connectors used in the LED display screen are of poor quality. Dead pixels refer to individual points on the display screen that are constantly lit or dark. The number of dead pixels is mainly determined by the quality of the LED chips.
