Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
The embodiment of the invention deeply analyzes the defects of the existing terminal and provides the user terminal and the working method thereof, so that the user terminal can provide the characteristic information of the user to the user, and the use experience of the user terminal is improved.
The hand is the organ where people make contact with the smart terminal most frequently, and is usually directly contacted by the hand and the touch screen of the smart terminal. Most touch screens used by terminals in the prior art are resistive touch screens or capacitive touch screens, wherein:
the multilayer structure of the resistive touch screen can cause great light loss, and the backlight source is usually required to be enlarged for the handheld device to compensate the problem of poor light transmission, but the battery consumption is increased.
The capacitive touch screen works by utilizing current induction of a human body, generally, the capacitive touch screen is a four-layer composite glass screen, the inner surface and the interlayer of the glass screen are respectively coated with a layer of Indium Tin Oxide (ITO), the outermost layer is a thin silica glass protective layer, the ITO coating of the interlayer is used as a working surface, and four electrodes are led out from four corners of the coating. The inner ITO layer is a shielding layer for ensuring a good working environment. When a finger touches, due to the action of the human body's electric field, the user and the touch screen surface form a coupling capacitance, which is a direct conductor for high frequency currents, so that the finger draws a small current from the contact point. The current flows out of the electrodes on the four corners of the touch screen, the current flowing through the four electrodes is in proportion to the distance from the finger to the four corners, and the controller obtains the position of the touch point through accurate calculation of the four current proportions.
