Problems solved by technology
For a flexible display device, the display screen includes a non-stretch display area and a stretchable display area, and the pixel design of the stretchable display area is compared with the pixel design of the non-stretch display area. On the basis of pixel design, it is formed by removing a certain part of the pixels in situ. For example, the pixel arrangement of the stretchable display area is obtained after removing the pixels at the positions corresponding to the holes in the pixel arrangement of the non-stretchable display area. That is to say, when the stretchable display area is not stretched and deformed, its pixel distribution is uniform with that of the non-stretched display area, and the display brightness is uniform. However, when stretched and deformed, the pixel distribution uniformity is broken, The pixel density of the stretchable display area decreases, resulting in a decrease in the brightness of the stretchable display area, resulting in a difference between the luminous brightness of the display panel in the overall stretchable display area and the luminous brightness of the non-stretchable display area

The present invention provides a display substrate, a manufacturing method thereof, and a display device. The display substrate includes: a non-stretch display area, including a plurality of first pixels arranged in an array, and the first pixels of the non-stretch display area The pixel pitch is the reference pitch P 0 and, a stretchable display area, the stretchable display area includes a plurality of islands distributed in an array and separated from each other, and a plurality of bridges connecting adjacent islands, each A pixel unit is arranged on the island area, and the pixel unit includes at least one second pixel, and a signal wiring electrically connected to each of the second pixels is arranged on the bridge area; wherein two adjacent pixel units The pitch in the stretching direction is the first pitch P 1 , the first pitch P 1 less than the reference pitch P 0 . The display substrate, its manufacturing method, and display device of the present invention can improve the difference in brightness between the stretchable display area and the non-stretch display area in the related art.
Description
technical field [0001] The present invention relates to the field of display technology, and in particular, to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] At present, flexible display devices are developing from two-dimensional direction variable to three-dimensional variable form. In order to increase the deformability of the flexible display device, a series of openings are generally arranged on the flexible substrate, which are divided into: the island area where the pixels are located and the bridge area where the connecting lines are located, so that the display device can be stretched and deformed. The pixels are arranged in the island area, and the signal lines are arranged on the bridge area. When external force is applied, the deformation mainly occurs in the bridge area, and the pixels in the island area basically maintain their shape. For flexible display devices, the display screen includes a non-stret...
