Abstract

The invention relates to an LED array display device with common redundant sub-pixel points. The LED array display device comprises densely arranged red, green and blue sub-pixel points, wherein one red sub-pixel point, one green sub-pixel point and one blue sub-pixel point constitute a light emitting pixel unit. The light emitting pixel unit surrounds a redundant sub-pixel point to form a pixel array unit; Furthermore, a plurality of pixel array units are densely arranged to form an LED array display device. The invention has the advantages that the life of the display array can be prolongedby the compensation of the redundant sub-pixel points to surrounding abnormal sub-pixel points, and the influence of the redundant sub-pixel points on the display array resolution can be minimized.

Description

technical field [0001] The invention belongs to the field of display technology, and relates to an LED display array redundant sub-pixel point arrangement technology, in particular to an LED array display device with shared redundant sub-pixel points. Background technique [0002] LED has attracted much attention due to its advantages of high efficiency, energy saving, small size, and long life. It has been widely used in the display field, such as outdoor large-area LED array displays, small-area OLED ultra-thin flexible displays, and micro-LED array displays. The device is also regarded as another display technology with thin and light and power-saving advantages after OLED display. However, regardless of the display technology, there is a problem of inaccurate color rendering after long-term use caused by different sub-pixel lifespans of different colors, and even affects the service life. [0003] For example, in OLED, its light-emitting layer is mainly composed of red ...
