DISPLAY DEVICE

摘要

A display device includes a display panel including data lines, gate lines crossing the data lines, and pixels arranged in a matrix form, a touch screen which is embedded in the display panel or is installed on the display panel, a data driving circuit supplying a data voltage to the data lines, a gate driving circuit supplying a gate pulse to the gate lines, and a touch sensing circuit which supplies a driving signal to lines of the touch screen and senses a touch input. The gate driving circuit alternately drives pull-down transistors connected in parallel to one gate line. The gate driving circuit drives one of the pull-down transistors or simultaneously drives the pull-down transistors during a drive period of the touch screen.

1. A driving device comprising:
a driving circuit configured to:
write data to pixels of a display panel during a display period of each frame period, andsupply a touch drive signal to lines of a touch screen included in the display panel to sense a touch input on the touch screen during a touch sensing period adjacent within each frame period to the display period, wherein the driving circuit includes a plurality of pull-down transistors connected in parallel to one gate line to selectively supply a gate low voltage to the one gate line, and wherein the driving circuit changes a drive state of at least one of the plurality of pull-down transistors between the display period and the adjacent touch sensing period within each frame period.
