Abstract: A touch sensor integrated display device includes a plurality of common electrode blocks that defines a plurality of touch driving channels and a plurality of touch sensing channels. The touch driving channel is formed of a group of common electrode blocks electrically linked via a touch signal line placed under the layer of the common electrode blocks. The source/drain of the circuit TFTs provided in the non-display area is formed of the same metal layer of the touch signal line. The source/drain of the pixel TFTs provided in the display area is formed of a metal layer different from the metal layer of the touch signal line.

Abstract: A display device may include: a display panel with subpixels connected respectively to scan lines, sensing lines, and data lines; a gate driver configured to supply a scan signal to the scan lines during an active period and to supply a sensing signal to the sensing lines during a sensing period of a blank period; a data driver configured to supply a data voltage to the data lines; and a timing controller configured to control the gate and data drivers. The timing controller may determine the active period, blank period, and sensing period to be, respectively: a first active period, a first blank period, and a first sensing period for operating at the first frame rate; and a second active period, a second blank period, and a second sensing period for operating at the second frame rate. The first sensing period and the second sensing period have a same length.
