An LED display uses an array of semiconductors to produce an image. These devices are typically used for billboards and store signs. They are a type of flat panel display. Because LEDs are so efficient, they are a great option for large-scale displays. However, there are still many challenges when choosing the right LEDs.
Below are four factors you need to consider when choosing an LED.
The dead spot of LED display is a single point that is always bright or always black on the display. The number of dead points is mainly determined by the quality of the tube core. The lower the dead point, the better the display effect of the LED display will be.
The color reduction of the LED display refers to the color displayed by the LED display must be highly consistent with the color of the broadcast source, so as to ensure the authenticity of the image.
The flatness of the LED display will affect the quality of the displayed image. The flatness of the cabinet surface of the indoor LED rental screen in the industry is kept within ±1mm, and the local bulge or recess on the cabinet surface will lead to a dead angle in the viewing angle of the LED display. The flatness is determined by the production process, and LED display manufacturers should pay attention to this problem during production.
The size of the viewing angle of the LED display directly determines the audience of the LED display. The larger the viewing angle, the wider the audience will be. The viewing angle is affected by the packaging method of the LED tube core. Therefore, when choosing an indoor LED rental screen, you should also pay attention to the packaging method of the tube core.
