  • Publication number: 20240296802
    Abstract: A driving circuit, a driving method, a display device, and a display control method are provided. The driving circuit includes multi-stage driving units and an on/off control circuit. Each of the driving units includes an input end and a driving signal output end, and each of the driving units is configured for outputting a corresponding driving signal via the driving signal output end according to an input signal provided by the input end. The input end of a first-stage driving unit is electrically connected to a start signal end. The on/off control circuit is electrically connected to an on/off control end and input ends of the multi-stage driving units, and configured for controlling the electric connection or electric disconnection of the input ends of the multi-stage driving units under the control of an on/off control signal provided by the on/off control end.

  • Patent number: 11296155
    Abstract: A display panel and an operation method thereof are disclosed. In the display panel, a second light-emitting device is configured to emit a second light ray to the non-display side, and a second photosensitive element is configured to allow the second light ray to be incident therein and detect the second light ray. A first light-emitting device and the second light-emitting device are configured to emit a first light ray to the display side, and a first photosensitive element is configured to allow the first light ray reflected by an external object to be incident therein and detect the reflected first light ray. The second light ray is of a type different from that of the first light ray.
