Abstract: A display substrate and related devices are provided. The display substrate includes a plurality of first sub-pixels, second sub-pixels and third sub-pixels. In a first direction, the first sub-pixels and the third sub-pixels are arranged alternately to form a plurality of first sub-pixel rows, the second sub-pixels form a plurality of second sub-pixel rows, the first sub-pixel rows and the second sub-pixel rows are arranged alternately in a second direction, connection lines of center points of two first sub-pixels and two third sub-pixels form a first virtual quadrilateral, the two first sub-pixels are located at two vertex angles of the first virtual quadrilateral which are opposite to each other, one second sub-pixel is located within the first virtual quadrilateral, and the first virtual quadrilateral includes two interior angles each being equal to 90° and two interior angles each being not equal to 90°.

Abstract: A mask sheet for evaporation on a substrate is provided, and the mask sheet includes: a plurality of first ribs extending in a first direction; and a plurality of second ribs extending in a second direction intersecting the first direction, the mask sheet includes a first region for an evaporation of a first exposure region of the substrate and a second region for an evaporation of a second exposure region of the substrate, a third rib is provided at a boundary of the first region and the second region so as to shield an overlapping exposure region between the first exposure region and the second exposure region, the third rib includes a first sub-rib, a second sub-rib, and a spacer for separating the first sub-rib and the second sub-rib, and the third rib has a width greater than that of the first rib.

Abstract: Provided is a mask assembly, including at least n evaporation masks, n being an integer greater than 2, wherein the at least n evaporation masks have a same width and the at least n evaporation masks respectively correspond to n types of display panels with different sizes, the width matching the n types of display panels with different sizes.
