Abstract

Provided is a display panel capable of avoiding image tearing or freezing, and suppressing degradation or flickering of gray scale performance caused by volatilization of image signals in pixel circuits. The display panel (10) includes: a panel portion (12) having a plurality of pixel circuits arranged in a matrix; a source driving circuit (16) providing the pixel circuits with image signals displayed on the panel portion (12); A pole drive circuit (14), which sequentially provides gate signals representing the timing of writing the image signal, that is, control signals WS1 to WSN, to the pixel circuit in row units; and a control terminal that receives a refresh stop signal, that is, a clear signal CLR, the gate drive circuit (14), stops supplying the control signals WS1 to WSN to the pixel circuits of the subsequent row when the control terminal receives the clear signal CLR during the supply of the control signals WS1 to WSN.

Description

technical field [0001] The present invention relates to a display panel, a control device for the display panel, a display device, and a driving method for the display panel. Background technique [0002] In computers and portable devices, images displayed on a display panel are generated by an image processing device called a GPU (Graphics Processing Unit: Graphics Processing Unit). The image generated by the GPU is composed of a plurality of frame images, and each frame image includes luminance data for each pixel. The data signal corresponding to the luminance data of each pixel is sequentially written in units of rows (that is, a refresh operation) to a plurality of pixel circuits arranged in a matrix on the display panel, and a frame image is displayed on the display panel. [0003] There is a display panel in which data signals are written to pixel circuits at a fixed refresh rate. Such a display panel assumes that a new frame image can be used every refresh cycle. ...
