Abstract: This application provides an electronic device, to reduce a probability that a screen stalling phenomenon. A timing control unit sends one first pulse of a tearing effect signal every a first preset time T1. The timing control unit sends S second pulses of the tearing effect signal when a transceiver unit does not receive an Nth frame of display data within a preset time. The processing unit receives the Nth frame of display data in the (N+1)th frame, and controls, based on the Nth frame of display data, the display to display an Nth frame of image.

Abstract: A terminal, comprising at least two front cameras located behind a display panel, wherein an area corresponding to a position of the at least one camera on the display panel is a first area, and other than the first area on the display panel is a second area, wherein each pixel unit of the first area and the second area respectively comprises a transparent portion and a non-transparent portion and a proportion of the transparent portion in the first area is greater than that of the second area. The terminal further comprises a processor configured to obtain N pictures taken by the at least two cameras, and process the N pictures by complementing the occluded areas based on pictures taken by the at least two cameras to obtain a picture in which the occluded area is completely or partially recovered.
