摘要： A display substrate includes a base, a voltage signal line, a driving circuit structure, a cathode overlapping layer and a cathode layer. The voltage signal line is located in the non-display region and is arranged around the display region. The driving circuit structure is located in the non-display region, and is located at a side of the voltage signal line proximate to the display region. The cathode overlapping layer is located in the non-display region and is arranged around the display region. At least a part of a surface of a first portion of the cathode overlapping layer proximate to the base is in electrical contact with a corresponding part of the voltage signal line. An orthographic projection of a second portion of the cathode overlapping layer on the base at least partially overlaps an orthographic projection of the driving circuit structure on the base. The cathode layer extends from the display region to the non-display region, an edge of the cathode layer is located in the non-display region, and the cathode layer is in electrical contact with at least a part of a surface of the second portion of the cathode overlapping layer away from the base.

摘要： Embodiments of the present disclosure provide a pixel array and a display device, and relate to the field of display technology. A pixel array according to the embodiments of the present disclosure includes a plurality of sub-pixels, which include first sub-pixels, second sub-pixels, and third sub-pixels. The first sub-pixels and the third sub-pixels are alternately arranged along a row direction and form a plurality of first pixel rows, the first sub-pixels and the third sub-pixels, which are in a same column, in the plurality of first pixel rows are alternately arranged, and the second sub-pixels are arranged side by side along the row direction and form a plurality of second pixel rows. Lines sequentially connecting centers of any two of the first sub-pixels and any two of the third sub-pixels, which are arranged in an array, together form a first virtual quadrilateral, and one of the second sub-pixels is in each first virtual quadrilateral. At least a portion of interior angles of the first virtual quadrilateral is not equal to 90°. A distance from an intersection point of extension lines of two sides of at least one vertex angle of at least one sub-pixel of the first sub-pixels, the second sub-pixels and the third sub-pixels to a center of the at least one sub-pixel is different from a distance from an intersection point of extension lines of two sides of another vertex angle of the at least one sub-pixel to the center of the at least one sub-pixel.

摘要： A mask and an evaporation device. The mask (100) includes a frame (101) and a first mask strip (1021) disposed inside the frame (101); the frame (101) includes an outer frame (1011) and an inner frame (1012); the outer frame (1011) is disposed on the outer side and includes a first plane (103); the inner frame (1012) is disposed on the inner side and includes a second plane (104); the first plane (103) is higher than the second plane (104), so as to form a step (105); the first mask strip (1021) is fixed on the outer frame (1011) through two ends and extended in the outer frame (1011) along one side of the frame (101); and an orthographic projection of the first mask strip (1021) on the second plane (104) is at least partially overlapped with the inner frame (1012) on the one side. The mask (100) changes the design of the frame (101) and the mask strips (1021, 1022) fixed thereon and therefore can effectively solve the problem of the scratching of a glass substrate and effectively improves the yield and the service life of subsequent products.
