[0116] This embodiment provides a method for defect detection of a touch panel, please refer to Figure 10 , the defect detection method of the touch panel may include the following steps.

[0117] Step S110 , scanning the touch panel to be tested, and determining whether there is a defect in the touch pattern of the touch panel to be tested according to the scanning result.

[0118] Please refer to the first embodiment for the specific scanning principle, and will not go into details here. When it is determined that the touch pattern of the touch panel to be detected is defective, enter step S120; when it is determined that the touch pattern of the touch panel to be detected does not exist When there is a defect, the defect detection of the touch panel to be detected is ended.

[0119] In this embodiment, this step can be implemented by using the touch panel scanning device 110 in the first embodiment.

[0120] Step S120, locating the target position area where the touch pa...

Abstract

The invention provides a touch panel defect detection system and a touch panel defect detection method provided. Defect scanning is carried out on a to-be-detected touch panel. When the to-be-detectedtouch panel has defects, a target position area where a defect is located is positioned through a pattern defect positioning device; the accurate position of the lethal defect in the image of the target position area is found; therefore, an image of the lethal defect is obtained. According to the scheme, the pattern of the lethal defect can be accurately snapshot from the positioned target position area, the snapshot accuracy of the lethal defect image is improved, and then defect detection is effectively carried out on the touch pattern of the touch panel.

Description

technical field [0001] The present application relates to the field of touch technology, in particular, to a touch panel defect detection system and a touch panel defect detection method. Background technique [0002] The touch panel generally includes touch patterns formed by different touch electrodes. After the touch panel is manufactured, if there is a defect in the touch pattern, it will affect the touch effect of the touch panel. Therefore, how to effectively detect the defects of the touch pattern on the touch panel is extremely important. Contents of the invention [0003] In order to overcome the technical problems mentioned in the above technical background, embodiments of the present application provide a touch panel defect detection system and a touch panel defect detection method. [0004] According to the first aspect of the present application, a touch panel defect detection system is provided, and the system includes a touch panel scanning device, a patte...
