    Abstract: Disclosed are a pixel arrangement structure, a metal mask, and a display device, and in the pixel arrangement structure, each repeating element includes four sub-pixels distributed in two rows by two columns, where the four sub-pixels include two first sub-pixels in different rows and different columns, and one second sub-pixel and one third sub-pixel in different rows and different columns. While an image is being displayed, any one first sub-pixel together with one second sub-pixel adjacent thereto and one third sub-pixel adjacent thereto can constitute a light-emitting pixel, so that the image can be displayed at a high resolution using a physical low resolution through borrowing between the sub-pixels.

    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.

    Abstract: The present disclosure provides a mask plate and a fabricating method thereof. The mask plate includes a patterning layer having a plurality of openings; a bonding region at a periphery of the patterning region and including a bonding part configured to be bonded to an external frame; and a transition region between the patterning region and the bonding region and including a transition part, the transition part adjoining the patterning layer and the bonding part, respectively; a thickness of the patterning layer is less than a thickness of the bonding part; and a thickness of a portion of the transition part adjoining the patterning layer is less than a thickness of a portion of the transition part adjoining the bonding part. The mask plate of the present disclosure can alleviate problem that the patterning layer is thin and easy to deform and has improved flatness of the patterning layer.
