Description

Technical Field

[0001] The utility model relates to the technical field of touch screen testing, and more specifically to a touch screen anti-fingerprint liquid testing device. Background Art

[0002] A touch screen is an inductive liquid crystal display that can accept input signals such as contacts. When the graphic button on the screen is touched, the tactile feedback system on the screen can drive various connected devices according to pre-programmed programs. It is a simple, convenient and natural way of interaction, which provides a new look for multimedia and has become an extremely attractive new multimedia interactive device. The working principle of the touch screen mainly relies on the current induction of the human body. There are many specific implementation methods, including resistive, capacitive, surface acoustic wave and infrared. Resistive touch screens are based on the contact between two layers of conductive films, and determine the position of the touch point by changing the current through pressure or voltage; capacitive touch screens are based on the change of capacitance of the human body, and determine the touch point by sensing the electric field generated by the electrode and the influence of the human body charge on the electric field distribution; surface acoustic wave touch screens are based on the propagation of sound waves, and use ultrasonic transmitters and receivers to detect the changes in sound waves to determine the touch point; and infrared touch screens are based on the reflection principle of infrared rays, and determine the touch point by detecting the changes in infrared rays. By setting anti-fingerprint liquid on the touch screen, fingerprints and grease can be prevented from adhering to the touch screen. For example, the anti-fingerprint liquid crystal display proposed in the publication number: CN204331218U, by setting the anti-fingerprint coating layer on the transparent conductive layer, the anti-fingerprint liquid crystal display can have anti-fouling performance, so that when a person operates on the anti-fingerprint liquid crystal display, no fingerprints or other traces are left, thereby ensuring the smoothness of the screen of the anti-fingerprint liquid crystal display;

Therefore, we have made improvements on this and proposed a touch screen anti-fingerprint liquid testing device. Utility Model Content
