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.

A detection circuit and a detection method for liquid crystal display are provided. The detection circuit comprises a gate driver for providing row scan signal to liquid crystal cell to be detected; a signal source for providing polarity inversion signal to source driver; a source driver for performing digital-analogue conversion on received display data signal according to preset reference voltage and polarity inversion signal, generating pixel voltage signal, and sending pixel voltage signal to liquid crystal cell to be detected. The polarity inversion signal comprises column polarity inversion signals each of which polarity inversion signal is continuous high level signal or continuous low level signal. The polarity inversion mode is a column inversion, which makes white dot of damaged area of alignment film is more prominent during detection process, so it would be easy for the operator to recognize it and avoid the issue of missing detection.
