In-cell touch display device

An in-cell touch display device (100). A panel (110) has a plurality of data lines (DL), a plurality of gate lines (GL) and a plurality of touch electrodes disposed thereon. A touch driving signal (TDS) is applied to the plurality of touch electrodes when a driving mode is a touch mode. A data drive...

description An in-cell touch display device (100). A panel (110) has a plurality of data lines (DL), a plurality of gate lines (GL) and a plurality of touch electrodes disposed thereon. A touch driving signal (TDS) is applied to the plurality of touch electrodes when a driving mode is a touch mode. A data driver (120) drives the plurality of data lines (DL). A gate driver (130) drives the plurality of gate lines (GL). The gate driver (130) sequentially outputs a scanning signal for driving the plurality of gate lines (GL) to the plurality of gate lines (GL) when the driving mode is a display mode, and outputs a load-free driving signal (LFDS_gate) corresponding to the touch driving signal (TDS) to at least one gate line (GL) when the driving mode is the touch mode. A level shifter (810) generates the load-free driving signal (LFDS_gate). A multiplexer (820) inputs a scanning voltage (VGH/VGL) or the load-free driving signal (LFDS_gate) to the gate driver (130) depending on the driving mode.
