Pixel arrangement structure, fine metal mask set and display apparatus
View Patent ↗The present disclosure provides a pixel arrangement structure, a fine metal mask set and a display apparatus. The pixel arrangement structure includes a plurality of sub-pixel repetition units along a first direction or a second direction. The plurality of sub-pixel repetition units each form a plurality of pixel units. The sub-pixel repetition units each include one or more first color sub-pixels, one or more second color sub-pixels and one or more third color sub-pixels. Each of the first color sub-pixels and each of the second color sub-pixels independently belong to one pixel unit respectively, and each of the third color sub-pixels is shared by two pixel units. The first direction intersects with the second direction.
