LED screen resolution

A full-color display is mainly from the following aspects to sign:
1 flatness
The surface smoothness of the display should be less than 1mm, to ensure that the display does not distort the image, the local convex or concave will lead to the viewing angle of the display. Flatness is mainly determined by the production process.

2 brightness and visual angle
Indoor full color brightness to above 800cd/m2, outdoor full color brightness to 1500 cd/m2 or more, in order to ensure the normal work of the image display, or because the brightness is too low and can not see the show. Brightness is determined by the quality of the LED core.
Visual angle directly determines the size of the audience, so the bigger the better. The size of the visual angle is determined by the encapsulation of the core.

3 white balance effect
White balance is one of the most important indicators of the display screen. Color on the popular green colors of the ratio of 1:4.6:0.16 only shows the pure white, there is a deviation if the actual percentage point deviation will appear white balance, the general attention to the bias of blue and white or yellowish green. The white balance is mainly decided by the control system of the display screen, and the core has an influence on the reduction of color.

4 color reducibility
The reduction of color refers to the reduction of the color of the screen, both the color of the display screen to play with the source of the color to maintain a high degree of consistency, so as to ensure the authenticity of the image.

5 there is no mosaic, dead phenomenon
Mosaic refers to appear on the screen lit or black box is often small, module necrosis, the main reason for the display quality of connector.
The dead point refers to a single point on the screen appear often bright or often black, the number of dead is mainly composed of a pipe core is determined.

6 there is no color
Color refers to the existence of obvious difference between adjacent modules, color transition to module as a unit, cause the color phenomenon is mainly controlled by the system is poor, gray level is not high, resulting in lower scanning frequency.
