| description | The present invention provides an LED display screen and a manufacturing method therefor. The method comprises: preparing batches of LED chips of same or different specifications; performing illogically grabbing on the LED chips by means of a random sampling method and arranging the grabbed LED chips in sequence; packaging the LED chips that are arranged in sequence and assembling same to form the LED display screen; wherein the adjacent LED chips in a certain area in the LED display screen are not all the adjacent LED chips of the same specification, and the specification of the LED chips comprises one of color and brightness. According to the method of the present invention, by performing once or multiple times of illogically grabbing on the chips of a single specification or multiple specifications and arranging same, a difference of the brightness and color does not occur in the chips that are grabbed and arranged in subsequent packaging and after the assembly of the screen. Furthermore, the method of the present invention can be implemented by using a random number table method in operation of an existing device; an implementation process is simple, and does not need to perform device or process changing or designing; operation costs are low; and the method can be easily implemented. |
