Abstract: A method for improving fault tolerance of a touchscreen determines an abnormal node, and shield the abnormal node to improve the fault tolerance of the touchscreen. The method includes detecting a capacitance value of each node in the touchscreen, comparing the detected capacitance value of each node with a preset capacitance value of each node to determine N target nodes, where N is an integer greater than or equal to zero, and the target nodes are nodes whose capacitance values vary, determining whether an abnormal node is included in the N target nodes, where the abnormal node is a target node determined when no touch operation occurs on the touchscreen, and discarding a row value, a column value, and a capacitance variation value of the abnormal node when the abnormal node is included in the N target nodes.

Abstract: A display panel includes an AMOLED light-emitting board and a light filter layer disposed on a cathode surface of the AMOLED light-emitting board. The light filter layer includes a color light filter and a diffusion film. The color light filter includes a red light filter component, a green light filter component, a blue light filter component, and a BM. The diffusion film is disposed on a surface of the color light filter, or is disposed on each light filter component in the color light filter. The diffusion film is configured to enable ambient light passing through the diffusion film to be incident on the cathode surface of the AMOLED light-emitting board in a direction that is not perpendicular to the cathode surface of the AMOLED light-emitting board.

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.
