Touchscreen display devices and methods for sensing touch input on touchscreen display devices.

Abstract

The invention reveals a touch display device and a display panel. The touch display device comprises a display panel consisting of touch electrodes arranged in touch blocks, each of which consists of a corresponding segment of touch electrodes; touch lines consisting of touch block lines connected to the touch blocks and touch electrode lines connected to the touch electrodes; and a touch control circuit constructed to sense the touch of the touch block from the touch blocks based on the first touch signal received from the touch block lines from the touch block lines connected to the touch block, and to sense the touch of the touch electrode from the touch electrodes contained in the touch block based on the second touch signal received from the touch electrode lines from the touch electrode lines connected to the touch electrodes.
