Abstract: A touch display device and a display panel uniformly distributing capacitances between the touch lines and the touch electrodes are provided. The device includes a display panel in which a plurality of X-touch electrodes are electrically connected to form a X-touch electrode line and a plurality of X-touch electrode lines arranged in parallel to receive a plurality of touch driving signals, and a plurality of Y-touch electrode lines to transmit a plurality of touch sensing signals, and a touch driving circuit. A plurality of X-touch lines transmit the touch driving signals connect together the plurality of X-touch electrodes constituting a same X-touch electrode line through a plurality of contact holes. Distances between at least one Y-touch electrode line and the plurality of contact holes through which the plurality of X-touch lines are electrically connected to the X-touch electrodes adjacent to the at least one Y-touch electrode line are uniform.

Abstract: Disclosed is an organic light-emitting diode display device including: a display panel in which pixels adjacent to each other are paired and arranged to share a single data line in pixel areas defined by gate and data lines; a gate driver configured to drive the plurality of gate lines; a data driver configured to output a data voltage to data voltage output channels on the basis of an arrangement of pixels; a data switcher configured to alternately select a data line and to electrically connect the data line with the data voltage output channel of the data driver; and a timing controller configured to control the data switcher and the gate and data drivers, thereby making it possible to drive a data driving circuit at high driving frequency and to reduce a deterioration of image quality and image distortion even in a simplified structure of the data driving circuit.
