1. Flatness.
The surface flatness of the LED display screen should be within 卤 1mm to ensure that the displayed image is not distorted, and local protrusions or recesses will cause a dead angle in the viewing angle of the display screen. The quality of the flatness is mainly determined by the production process.
2. Brightness and viewing angle.
The brightness of the indoor full-color screen must be above 800cd / m2, and the brightness of the outdoor full-color screen must be above 1500cd / m2 to ensure the normal operation of the display screen, otherwise the displayed image will not be clear because the brightness is too low. The brightness is mainly determined by the quality of the LED lamp beads. The size of the viewing angle directly determines the number of LED display audiences, so the larger the better. The size of the viewing angle is mainly determined by the packaging method of the die.
3. White balance effect.
White balance effect is one of the most important indicators of LED display. Chromatically, pure white is displayed when the ratio of the three primary colors of red, green and blue is 1: 4.6: 0.16. If there is a slight deviation in the actual ratio, there will be a deviation in white balance. Generally, it is necessary to pay attention to whether the white is blue or yellow. Green phenomenon. The quality of the white balance is mainly determined by the control system of the LED display, and the lamp beads also have an effect on the reduction of color.
4. Color reducibility.
The color reproducibility refers to the color reproducibility of the LED display, that is, the color displayed on the LED display must be highly consistent with the color of the source, so as to ensure the authenticity of the image.
5. Product design.
There are many types of full-color LED displays. Indoor and outdoor energy-saving, high-brightness, high-refresh, portable and other products are available. The requirements for LED displays are different in all walks of life. Therefore, when buyers distinguish between LED displays and choose LED displays To meet your own needs, whether the manufacturers' LED display products can best meet your needs.
