Method for triggering capacitive touch screen without human body touch

Abstract

The invention relates to a method for triggering a capacitive touch screen without human body touch. Conventional capacitive touch screens need operators to operate with fingers; certain exceptional capacitive touch screens which adopt stylus also need to directly contact with the fingers of the operators, and the operators have to stay within a distance to the capacitive touch screen so as to operate with hands. The invention adopts a conductive material made of a conductive contact; one end of the conductive material is connected with the power anode of a driving device; the conductive material is enabled to contact with the capacitive touch screen through transmission; the conductive material remains in contact with the capacitive touch screen for a period of time; when the conductive material leaves the capacitive touch screen, the capacitive touch screen can be triggered once; and the driving mode can be a motor or a coil device. The control mode can be that a remote control system can be loaded to realize remote control. The invention can reach the effect that an electronic product with the capacitive touch screen can be put in a distance away from an operator, and the electronic product can realize remote control in distance, thus expanding the application range of electronic products with the capacitive touch screens, and the electronic products are convenient and flexible to operate, which is good for popularization.

Description

technical field [0001] The invention belongs to the field of electronics, and in particular relates to a method for triggering a capacitive touch screen by non-human contact. Background technique [0002] At present, the structure of the capacitive touch screen is mainly to coat a layer of transparent film on the glass screen, and then add a protective glass outside the conductor layer. The double glass design can completely protect the conductor layer and the sensor. [0003] The capacitive touch screen is plated with long and narrow electrodes on the four sides of the touch screen, forming a low-voltage AC electric field in the conductor. When touching the screen, due to the electric field of the human body, a coupling capacitance will be formed between the finger and the conductor layer, and the current from the electrodes on the four sides will flow to the contacts, and the current strength is proportional to the distance from the finger to the electrode. The controller ...

AI Technical Summary

Problems solved by technology

When the distance between the human body and the capacitive touch screen is long, or the capacitive touch screen cannot be directly manipulated with fingers, the purpose of controlling the capacitive touch screen cannot be achieved, which greatly affects the application of the capacitive touch screen in the electronic field.
