Abstract: A dimming method and device of a display panel, a storage medium, and a terminal equipment are provided. In a second dimming stage in a frame of one frame of an image, a grayscale of a light-emitting stage of the display is controlled by the light-emitting signal. In a first dimming stage in the frame of the image, the grayscale of the light-emitting stage of the display panel is controlled by superposing a control signal in the light-emitting signal. Therefore, in a low grayscale, the grayscale is realized by reducing an amplitude of the light-emitting signal.

Abstract: A manufacturing method of a display panel and a display panel are disclosed. In the manufacturing method of the display panel, a film is formed on a substrate, and a slit is formed on the film, and then a metal film is formed on the film and is deposited on a surface of the substrate through the silt. After tearing the film and the metal film therewith, the metal film deposited on the surface of the substrate can form a metal line on the surface of the substrate to improve the transfer efficiency of the metal in the metal film to the surface of the substrate to form the metal line, and shorten the process time.

Abstract: The present invention provides a method of calculating an intensity of light leakage by extracting geometric design parameters of a curved display device and establishing a finite element model according to the geometric design parameters. The finite element model is subjected to bending deformation, and according to an obtained stress and a conversion relationship, a complex amplitude matrix and the intensity of light leakage of the curved display device are obtained. As such, the intensity of light leakage calculated in the present invention is more accurate, and a better reference can be provided for a design of the curved display device.

Abstract: The present application provides a gate driving circuit and a display panel. The gate driving circuit includes a plurality of cascaded gate driving units, where each of the plurality of cascaded gate driving units includes a pull-up control module, an inversion module and a feedback module. The potential of the pull-up node is stepwise increased by the pull-up control module, so that the feedback module can be controlled to be turned off by the inversion module when the potential of the pull-up node is lower, thereby improving a phenomenon of leakage of the pull-up node through the feedback module.
