Abstract: A display panel has a display area and a non-display area surrounding the display area, and includes photosensitive components and a photosensitive driving circuit. The photosensitive components are used to sense ambient light, and the photosensitive driving circuit is connected to the photosensitive components to drive the photosensitive components. The photosensitive driving circuit is disposed in the non-display area, and at least a part of the photosensitive components is disposed in the non-display area.

Abstract: A method, device, and display device for detecting ambient light are provided. The method includes obtaining brightness information of the ambient light, determining a brightness interval of the ambient light according to the brightness information of the ambient light and preset correspondences between a plurality of ambient light sensors and different brightness intervals, using the ambient light sensor corresponding to the brightness interval of the ambient light as a reference sensor, and outputting a brightness signal of a current ambient light according to output signals of the ambient light sensors and a preset conversion formula.

Abstract: The present disclosure relates to an in-cell touch display panel and an electronic device. The in-cell touch display panel includes a plurality of photo spacers (PSs) being configured to stand on the protection layer along an extending direction of the virtual lines, and the virtual lines are disconnected in standing locations of the PSs. The PSs avoid the metallic wiring layer, and the standing locations of PSs are more flat. As such, the supporting height of the PSs are the same, and the cell thickness is uniform. The dark stripe issue caused by the configuration of the PSs may be avoided, and so does the un-recoverable Push Mura, water ripple, and bright and dark spots. At the same time, the surface pressure and the display performance of the in-cell touch display panel may be enhanced.

Abstract: An in-cell touch display panel and an electronic device are provided. The in-cell touch display panel includes a plurality of photo spacers (PSs) configured to stand on a protection layer along a direction in which dummy lines extend. The dummy lines are disconnected in standing locations of the PSs. The PSs are arrange to avoid a metallic wiring layer, and the standing locations of PSs are flatter. As such, supporting height of the PSs are the same, and a cell thickness is made uniform. The dark stripe issue caused by the configuration of the PSs may be avoided, and so does the un-recoverable Push Mura, water ripple, and bright and dark spots. At the same time, the surface pressure and the display performance of the in-cell touch display panel may be enhanced.
