摘要： The present disclosure relates to a touch display device and a driving method for the touch display device. The touch display device comprises data lines, gate lines, pixel electrodes located within display areas defined by the data lines and the gate lines, and a driving circuit. The driving circuit is configured to provide a first display data signal to the data lines during a display stage of the touch display device, and is configured to provide a second display data signal to the data lines during a predetermined period adjacent to the display stage within a touch stage of the touch display device, and provide an off-signal to the gate lines during the predetermined period such that the second display data signal is not provided to the pixel electrodes.

摘要： A method for debugging the display panel includes: acquiring a target correction data table of the display panel in each of at least one color mode by debugging the display panel in each of the at least one color mode. Debugging the display panel in each of the at least one color mode includes: controlling the display panel to display a test picture in the color mode; acquiring an initial display parameter curve based on a display parameter of the test picture; determining a reference display parameter curve based on the initial display parameter curve and a standard display parameter curve; and determining the target correction data table based on the reference display parameter curve and the standard display parameter curve.
