2results about How to "Improve display stability" patented technology

The application discloses a display device and a display control method, and belongs to the technical field of display. The display device comprises a display panel, a display driving module and a backlight module. A pixel array in the display panel comprises a plurality of pixel groups, and each pixel group comprises a plurality of pixel rows in the pixel array. One display frame period comprises a plurality of display subframes corresponding to the pixel groups. One display subframe comprises a scanning and writing sub-time domain, a liquid crystal response sub-time domain and a backlight driving sub-time domain arranged in sequence. The display driving module is used for writing display data into the pixel group corresponding to the display subframe in the scanning and writing sub-time domain in the display subframe in a first display mode. The backlight module is used for providing backlight for the display panel in the backlight driving sub-time domain in the display subframe in the first display mode. The display device provided by the application eliminates the visual flicker problem of the liquid crystal display panel caused by the excessively low frequency of the backlight turning on at a low refresh rate.

This application discloses a display panel, a display module, and a display device. The display panel includes a display area and a non-display area, with the non-display area surrounding the outer periphery of the display area. The display panel also includes a substrate, a light-shielding layer, a driving circuit layer, a light-emitting device layer, and an encapsulation layer. The substrate has a first side and a second side disposed opposite to each other along a direction perpendicular to its thickness. The light-shielding layer is disposed on the first side of the substrate and is located in the non-display area. The driving circuit layer is disposed on the side of the light-shielding layer away from the substrate and includes metal traces located in the non-display area. The orthographic projection of the metal traces onto the substrate is located within the orthographic projection of the light-shielding layer onto the substrate. The light-emitting device layer is disposed on the side of the driving circuit layer away from the substrate and includes a plurality of spaced-apart light-emitting units located in the display area. The encapsulation layer is disposed on the side of the light-emitting device layer away from the substrate, thereby improving the performance of the display panel.
