Abstract: A metal mask plate and a fabrication method thereof. The metal mask plate has a first main surface and a second main surface opposite to each other, the metal mask plate includes: a plurality of panel-defining regions spaced apart; and a main frame portion. In each of the panel-defining regions, a plurality of via holes configured for defining a pixel structure are arranged in a matrix, and each of the via holes communicates the first main surface and the second main surface of the metal mask plate, side walls of every two adjacent via holes are directly connected with each other on the second main surface of the metal mask plate so that the metal mask plate between the two adjacent via holes (101) in the panel-defining region has a thickness D1. The main frame portion of the metal mask plate has a second thickness D2, and the first thickness D1 and the second thickness D2 satisfy |D1−D2|/D1≤20%. Thus, a wrinkle and deformation caused by the difference of the thicknesses during unfolding can be effectively avoid, so as to further effectively improve quality of the OLED display product fabricated by adopting the fine metal mask plate.

Abstract: The present disclosure provides a display panel comprising multiple first, second and third sub-pixels having first, second and third effective light-emitting regions respectively. In a row direction, the first effective light-emitting regions form first rows of effective light-emitting regions, and the second and third effective light-emitting regions are alternately arranged to form second rows of effective light-emitting region. The first and second rows are alternately arranged in a column direction perpendicular to the row direction. A virtual quadrilateral is formed by lines connecting geometric centers of gravity of four first effective light-emitting regions in two adjacent rows and two adjacent columns. Geometric centers of gravity of the second and third effective light-emitting region are located in corresponding virtual quadrilaterals respectively. The second effective light-emitting region comprises at least one first curved edge, and/or the third effective light-emitting region comprises at least one second curved edge.

Abstract: The present disclosure provides a display substrate and a display device. The display substrate includes a plurality of sub-pixels in rows. The sub-pixels in each row includes first sub-pixels, second sub-pixels and third sub-pixels arranged alternately, and two adjacent rows of sub-pixels are arranged in a staggered manner. In every two adjacent rows of sub-pixels, each first sub-pixel in one row of sub-pixels and the second sub-pixel and the third sub-pixel adjacent to the first sub-pixel in another row of sub-pixels form a pixel. White brightness centers of the pixels in a same pixel row are located on a same straight line, and a brightness center of the first sub-pixel is not on a same straight line as the brightness centers of the second sub-pixel and the third sub-pixel located in a same sub-pixel row.
