摘要： A display substrate and a display apparatus. The display substrate comprises: a base substrate; and a plurality of sub-pixels, which are located on the base substrate, wherein the shape of an orthographic projection of at least one sub-pixel on the base substrate comprises a first shape, which comprises a first bending edge and a second bending edge; two ends of the first bending edge are respectively connected to two ends of the second bending edge, so as to form a first connection point and a second connection point; the length of a first connection line between the first connection point and the second connection point is the maximum length of the first shape in the extension direction of the first connection line, and the first shape is divided by the first connection line into a first sub-part comprising the first bending edge and a second sub-part comprising the second bending edge; and the area of the first sub-part is greater than the area of the second sub-part, and the maximum vertical distance between each point on the first bending edge and the first connection line is greater than the maximum vertical distance between each point on the second bending edge and the first connection line. In this way, the display substrate can reduce or even avoid a color separation phenomenon.

摘要： The present disclosure provides a display substrate, a display panel, an electronic device and a display method. The display substrate includes first electrodes in a first display region and second electrodes in a second display region, a first light-emitting portion in the first display region and a second light-emitting portion in the second display region, and the first electrodes being of strip shapes extending along a first direction and being spaced apart from each other along a second direction; third electrodes in the first display region and a fourth electrode in the second display region, the third electrode being of strip shapes extending along the second direction and being spaced apart from each other along the first direction. The first electrodes and the third electrodes are arranged in an intersecting manner to form a plurality of intersections, a part of the intersections form light-emitting units, and a part of the intersections form virtual light-emitting units. Due to virtual light-emitting units being formed in the first display region, driving control IC is relatively simple, and a light transmittance of a screen is relatively high, it is able to arrange an under-screen camera in the first display region, so as to ensure photographing effect of the camera.
