Problems solved by technology
[0004] The defects of the traditional touch screen detection method are: (1) Because some touch screens have poor induction in some areas, or some sensing points in the X-axis and Y-axis directions are disconnected or poorly connected, the traditional detection method cannot Effectively detect all touch areas of the touch screen, so the accuracy of the detection results is not high; (2) Since workers need to click on different positions of the touch screen, the detection efficiency is low

Embodiment 1
[0034] Embodiment 1. In order to avoid the problem of inaccurate detection results due to the fact that some sensing areas of the touch screen are not detected in the touch screen detection method of this embodiment, the method of drawing diagonal lines on the touch screen is used to make the resulting sensing The point coordinates can traverse all the values of the X-axis and Y-axis, and then by detecting the coordinates of the X-axis and Y-axis, the complete detection of all sensing areas on the touch screen can be realized, and accurate detection results can be obtained. It has the advantages of simple operation and high test efficiency. Advantage.
[0035] Combine below Figure 4 The flow chart shown in this embodiment describes in detail the specific design process of the touch screen detection method proposed in this embodiment.
[0036] S401. Enter a touch screen detection mode.

The invention discloses a touch screen detection method and electronic products. The method is characterized by touching and sliding on a touch screen along the diagonal direction, receiving feedback coordinate values of the touch screen and judging the touch screen to be normal if all the X-axis and Y-axis numerical values are detected when detection is performed for the touch screen. Each sensing area of the touch screen is judged to be normal or not by simple diagonal sliding touch operation and by a method of detecting whether all the X-axis and Y-axis numerical values are traversed or not. Compared with a traditional scheme, the touch screen detection method is simple in operation, high in detection speed and high in accuracy rate of detection results. Production detecting efficiency of the electronic products can be remarkably improved while fault rate of manufactured products is decreased by applying the method to various electronic products needing to be assembled with touch screens.
Description
technical field [0001] The invention belongs to the technical field of electronic device detection, and in particular relates to a detection method for testing the performance of a touch screen and an electronic product designed using the detection method. Background technique [0002] With the rapid popularization of mobile phone products in the world, the demand for mobile phones continues to increase, and the frequency of users replacing mobile phones is increasing. Therefore, the production of mobile phones pursues high-efficiency testing. And along with the rapid development and widespread favor of smart mobile phones, the application of touch screens on mobile phones has become more extensive. [0003] Before the mobile phone leaves the factory, a test must be done on the performance of the touch screen to determine whether the function of the touch screen is normal, including the performance of the touch screen itself, the connection line between the touch screen and ...
