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.
