Technical Field

[0001] The utility model relates to the technical field of touch screen detection, in particular to a production detection device for a mobile phone touch screen. Background Art

[0002] A mobile phone touch screen, also known as a mobile phone touch control screen, is an inductive liquid crystal display device that can receive input signals such as contacts. When a graphic button on the screen is touched, the tactile feedback system on the screen can drive various connection devices according to a pre-programmed program, which can be used to replace a mechanical button panel and create vivid audio and video effects through a liquid crystal display screen. In the production process of mobile phone touch screens, a detection device is needed to detect them. Existing mobile phone touch screen detection devices usually use fixed-shaped contacts to click on the touch screen. However, different people have different usage habits, and the size of the touch points on the screen displayed on the mobile phone touch screen is also different, resulting in this detection method being unable to adapt to the increasingly complex mobile phone application scenarios. For this reason, we propose a mobile phone touch screen production detection device. Utility Model Content
