Display Device Including Touch Screen and Driving Circuit for Driving Display Device

摘要

A display device including a touch screen and a driving circuit of the display device are disclosed. A display panel of the display device is driven while being divided into a first block, to which data is applied during a first display period, and a second block, to which data is applied during a second display period following a touch sensing period. A display driving circuit includes an (N−1)th stage driving a last gate line of the first block and an Nth stage driving a first gate line of the second block. The Nth stage includes a charger charging a Q node of the Nth stage in the touch sensing period in response to a multi-start signal before the second display period starts.

主权项

1. A display device including a touch screen comprising:
a display panel including:
pixels at intersections of data lines and gate lines, grouped into a plurality of blocks, and dividedly driven, anda plurality of touch electrodes; a display driving circuit configured to apply data of an input image to the pixels in a plurality of display periods divided from one frame period including at least a first display period and a second display period; a touch sensing unit configured to drive the touch electrodes in a touch sensing period assigned between the first display period and the second display period of the one frame period; and a timing controller configured to generate a multi-start signal including a plurality of pulses at predetermined time intervals in the one frame period, and wherein a first block of the display panel is driven during the first display period, and a second block of the display panel adjacent to the first block is driven during the second display period following the touch sensing period, wherein the display driving circuit includes an (N−1)th stage driving a last gate line of the first block and an Nth stage driving a first gate line of the second block, and wherein the Nth stage includes a charger configured to charge a Q node of the Nth stage in the touch sensing period in response to the multi-start signal before the second display period starts.
