Touch display device, driving circuit and automatic defect detection method

The invention discloses a touch display device, a driving circuit and an automatic defect detection method. The touch display device comprises a touch display panel and the driving circuit. The touch display panel is configured to perform display and touch sensing, and includes a plurality of touch sensing pads. The driving circuit is coupled to the touch display panel, is configured to provide a voltage signal containing a test pattern to the touch sensing pads, and is configured to determine whether the touch display panel has an open circuit or a short circuit from a detection signal in response to the voltage signal. According to the invention, automatic flaw detection can be carried out on the touch display panel, and the detection efficiency is further improved. 一种触控显示装置、驱动电路和自动瑕疵侦测方法，触控显示装置包含触控显示面板和驱动电路。触控显示面板经配置为进行显示和触控感测，且其包含多个触控感测垫。驱动电路耦接至触控显示面板，其经配置为提供含测试型样的电压信号至此些触控感测垫，且经配置为从响应于电压信号的侦测信号判别触控显示面板是否具有开路或短路。本发明可对触控显示面板进行自动瑕疵侦测，进一步提升检测效率。
