Abstract: A gate driving circuit and a display panel. The gate driving circuit includes a plurality of cascaded gate driving units, wherein a Nth stage gate driving unit includes a pull-up control module and a node signal control module. By an adjustment of the signals connected to a first input terminal, a second input terminal, a first control terminal, and a second control terminal of the node signal control module, an original driving time sequence can be realized without using a clock signal, which reduces a space occupied by a frame.

Abstract: A curved display panel and a curved display device are disclosed in the present application. The curved display panel includes a plurality of sub-pixels. The curved display panel has a central line and a central display area, and the central display area is symmetrical with respect to the central line. Aperture ratios of the sub-pixels located in the central display area gradually increase along a direction from a position away from the central line to the central line, and a difference between the aperture ratios of adjacent two of the sub-pixels is less than or equal to 2%. The split-screen probability of the curved display panel is reduced in the present application.

Abstract: A display panel and a display device are disclosed. The display panel comprises a display area and a light-transmitting area, and at least one alignment layer is provided with a hole in the light-transmitting area. In the present application, a hole is provided in at least one alignment layer of the display panel. Therefore, when external light enters the optical element through the display panel, the filtering effect of the alignment layer on the light is greatly reduced, and light loss is reduced, to improve the light transmittance of the area of the display panel corresponding to the optical element to effectively increase the amount of light collected by the optical element.
