Abstract

A display substrate, a method for driving the same, a display device, and a high-precision metal mask are provided. The display area includes a first display sub-area in which pixels are distributed at a high density (e.g., a high resolution), and a second display sub-area in which pixels are distributed at a low density (e.g., a low resolution), and a transition display sub-area, with a distribution density of pixels (a resolution) between the distribution density of pixels in the first display sub-area and a distribution density of pixels in the second display sub-area, is arranged between the first display sub-area and the second display sub-area.
