Abstract

The invention provides a display substrate and a display device. A display area of the display substrate comprises a bending area and a non-bending area adjacent to the bending area. The display substrate comprises a substrate, a light-emitting layer located on the substrate and an auxiliary layer located on the light-emitting layer. The light-emitting layer comprises a plurality of sub-pixels anda plurality of compensation pixels located in the bending area, and the plurality of sub-pixels are arranged in the bending area and the non-bending area. The auxiliary layer comprises shading partsin one-to-one correspondence with the compensation pixels and light-transmitting parts adjacent to the shading parts; and when the display substrate is in an unfolded state, orthographic projections of the compensation pixels on the substrate fall into the orthographic projections of the corresponding shading parts on the substrate. When the display substrate is in an outward folding state, a distance between every two adjacent compensation pixels is less than the distance between every two corresponding shading parts, and at least parts of light emitted by the compensation pixels is emitted out through the light transmitting parts.

Description

technical field

[0001] The present application relates to the field of display technology, in particular to a display substrate and a display device. Background technique

[0002] A display device with a flexible screen is small in size when folded and is easy to carry, and has a large effective display area when unfolded, which can improve user experience. The above advantages make foldable display devices more and more widely used.

[0003] When the display device is in the outwardly folded state, the display area of ​​the bending area of ​​the display device becomes larger, so that the display brightness of the bending area is lower than that of the non-bending area, affecting user experience. Contents of the invention

[0004] According to a first aspect of the embodiments of the present application, a display substrate is provided. The display area of ​​the display substrate includes a bending area and a non-bending area adjacent to the bending area, and the display...
