Abstract
A touch display comprises a color filter substrate, an array substrate opposite to the color filter via a plurality of spacers and a voltage detection circuit. The color filter substrate comprises an upper substrate and a common electrode formed on the upper substrate, and the array substrate comprises a lower substrate and a gate line, a data line and a pixel electrode formed on the lower substrate. The plurality of spacers comprise a first spacer formed between the gate line and the common electrode and a second spacer formed between the data line and the common electrode , which are capable of electrically connecting the common electrode with the gate line and the data line respectively under an external pressure more than a threshold value. The voltage detection circuit is connected with the gate line and the data line so as to detect whether the voltage on the gate line and the voltage on the data line become equal to the voltage of the common electrode.
