55 inch indoor screen advertising digital signage
What should you pay attention to when buying an indoor display?
1. Dead point
The dead point of the indoor display screen is a single point that emphasizes the always-on or always-black on the current display screen. Several keys of the dead point are determined by the quality of the die. The lower the dead point, the higher the display effect will be.
2. Chromaticity
The chromaticity is very harmful to the indoor display screen. If the chromaticity is too high, it is easy to damage the body's vision and health. If the chromaticity is too low, the display image will be unclear. Under normal circumstances, the chromaticity of indoor display screens is 800cd/㎡-2000cd/㎡. Different brands of LED display products have different chromaticities.
3. Color oxidation
The oxidative property of the indoor display screen means that the color of the display screen should be consistent with the color of the playback source, so as to ensure the reality of the image.
4. Flatness
The flatness of the display screen can compromise the quality of the displayed image. The flatness of the car body surface of the indoor display screen in the industry is maintained within ±1mm. Part of the protrusion or depression of the car body surface will cause a blind spot in the viewing angle of the display screen. The quality of flatness is determined by the processing technology, and indoor display manufacturers should pay attention to this problem when manufacturing.
5. Viewing angle
The size of the viewing angle of the indoor display screen is one of the main factors in the decision of the target group of the LED display. The larger and higher the viewing angle, the wider the target group, and the viewing angle is affected by the packaging method of the LED die. Therefore, pay attention to the packaging method of the die when selecting an indoor display screen.
