Abstract

The invention provides a touch display panel and a crack detection method thereof, and the touch display panel comprises a display panel which comprises a thin film packaging layer; and a touch control layer which is arranged on the thin film packaging layer, wherein the touch control layer is provided with a touch control area and a peripheral area located outside the touch control area, and the touch control layer comprises a first crack detection line arranged in the peripheral area. Cracks in the thin film packaging layer are detected through the first crack detection line which is arranged in the touch control layer and located on the thin film packaging layer.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a touch display panel and a crack detection method thereof. Background technique [0002] With the development of display technology and popularization of applications, the application market of organic light-emitting diode display panels continues to expand due to their advantages of high response, high contrast, and flexibility. [0003] During the manufacturing process of the OLED display panel, cracks may appear in the encapsulation layer of the OLED display panel, and water vapor will invade the organic light-emitting material through the cracks and affect the normal display of the OLED display panel. Therefore, detection of cracks in the thin film encapsulation layer of the OLED display panel is very necessary. Contents of the invention [0004] The purpose of the present application is to provide a touch display panel and a crack detection method thereof, so ...
