Abstract

The invention discloses a detection method for detecting a full-screen fingerprint touch screen. The detection method includes: providing a test template, the shape and size of the test template are corresponding to the sensing area of ​​the full-screen fingerprint touch screen, the test template includes a test pattern; storing the test pattern as a standard image; The template is applied to the sensing area of ​​the full-screen fingerprint touch screen to be detected to obtain a test image; and the test image is compared with the standard image to determine whether the quality of the full-screen fingerprint touch screen to be detected is qualified. The invention also provides a detection device. In this way, the test template can completely cover the sensing area of ​​the full-screen fingerprint touch screen, thereby avoiding the phenomenon of detection blind spots when using finger detection, realizing a more comprehensive detection of the full-screen fingerprint touch screen, and using the test template to reduce the manual operation steps of pressing fingers, making the quality judgment process Simple and convenient, it is beneficial to improve the efficiency of production line operations and reduce the cost of judgment.

Description

technical field [0001] The invention relates to detection technology, in particular to a detection method and a detection device. Background technique [0002] The sensing area of ​​the full-screen fingerprint touch screen is large, so the finger cannot cover the entire sensing area during detection, and multiple pressing methods are required. This is not only inefficient, but also may still have detection blind spots, which will affect the accuracy of detection. Utility model content [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention provides a full-screen fingerprint touch screen quality detection method and detection device. [0004] The detection method of the embodiment of the present invention is used to detect a full-screen fingerprint touch screen, which includes: [0005] Provide a test template, the shape and size of the test template correspond to the sensing area of ​...
