Display device with integrated touch screen and method of driving the same

摘要

The display device with integrated touch screen includes a panel configured to time-division operate during first and second display durations and first and second touch durations at every frame, a touch IC configured to apply a touch scan signal to a plurality of electrodes to allow the panel to perform touch driving during the first and second touch durations, and a display driver IC configured to, when the first touch duration of an n+1st frame is started, transfer display information about the second display duration of an nth frame and display information about the first display duration of the n+1st frame to the touch IC, and when the second touch duration of the n+1st frame is started, transfer display information about the first display duration of the n+1st frame and display information about the second display duration of the n+1st frame to the touch IC.

1. A display device with integrated touch screen, the display device comprising:
a panel configured to time-division operate during a first display duration, a first touch duration, a second display duration, and a second touch duration at every frame; a touch IC configured to apply a touch scan signal to a plurality of electrodes to allow the panel to perform touch driving during the first and second touch durations; and a display driver IC configured to, when the first touch duration of an n+1st frame is started, transfer display information about the second display duration of an nth frame and display information about the first display duration of the n+1st frame to the touch IC, and when the second touch duration of the n+1st frame is started, transfer display information about the first display duration of the n+1st frame and display information about the second display duration of the n+1st frame to the touch IC, wherein the touch IC compensates for a touch sensitivity by using transferred display information about the first and second display duration.
