Title:
PIXEL ARRANGEMENT STRUCTURE, ORGANIC ELECTROLUMINESCENT DEVICE, DISPLAY DEVICE, AND MASK
Document Type and Number:
WIPO Patent Application WO/2018/090630
Kind Code:
A1
Abstract:
Provided is a pixel arrangement structure comprising a plurality of pixel groups arranged repeatedly, each pixel group comprising four pixels. A first pixel (310) and a second pixel (320) are arranged in the same row, and a third pixel (330) and a fourth pixel (340) are arranged in another adjacent row. The first pixel (310) and the third pixel (330) are arranged in the same column and the second pixel (320) and the fourth pixel (340) are arranged in another adjacent column. The arrangement of sub-pixels in the first pixel (310) is different from the arrangement of sub-pixels in the second pixel (320), the arrangement of the sub-pixels in the third pixel (330) is the same as the arrangement of the sub-pixels in the second pixel (320), and the arrangement of the sub-pixels in the fourth pixel (340) is the same as the arrangement of the sub-pixels in the first pixel (310). The pixel structure makes an aperture area of the metal mask for manufacturing the pixel arrangement structure large, thereby improving the aperture ratio and improving the brightness, the lifespan and the definition of the AMOLED product. Also provided are an organic electroluminescent device, a display device, and a mask.
