Abstract

A thin film transistor array substrate in a touch display panel having reinforced common voltage uniformity on sub-electrodes therein includes a common electrode layer, a driving circuit, a controlling switch, a plurality of first lines, at least one second line, and at least one third line. The common electrode layer includes the spaced sub-electrodes. Each sub-electrode uses a first line electrically connect to the driving circuit and the controlling switch. The at least one second line is electrically connected to the driving circuit and the controlling switch, and when the controlling switch is turned on, the second line is electrically connected to the first lines, the driving circuit thus applying a common voltage to the sub-electrodes. A touch display panel using the thin film transistor array substrate is also provided.
