TOUCH SCREEN DISPLAY DEVICE

Abstract

The invention proposes a touch-sensitive display device whose touch sensing accuracy is enhanced within its perimeter. This touch-sensitive display device comprises: a display panel containing data lines, curves, subpixels, and touch electrodes with subpixels; a touch power circuit configured to generate and output a modulated pulse width; a gate control circuit configured to provide a black scan signal for the gate lines; a display controller configured to output a control signal for the gate control circuit that controls the timing of the gate control circuit; a first line in the non-display area of ​​the display panel to receive the gate control circuit control signal; and a second line in the non-display area to receive the pulse width signal, such that the width of the second line is greater than the width of the first line.
