ICIn-cell touch type display device and driving IC thereof

摘要

An object of the present invention is to provide a method for improving the problem of deterioration of touch performance due to RC delay caused by capacitive load between sensing wirings and signal wirings in an in-cell touch type liquid crystal display having a GIP structure. To this end, the present invention configures a load reduction circuit connected to the gate wiring and operates the load reduction circuit in the touch sensing section to output the same signal as the touch driving signal applied to the sensing wiring to the corresponding gate wiring. Accordingly, the capacitive load between the sensing wiring and the gate wiring is minimized, and distortion of the touch driving signal applied to the sensing wiring is minimized, thereby improving the touch performance.
