Non-contact pressing knob touch screen and function starting method thereof

Abstract

The invention relates to the technical field of electronics, in particular to a touch screen with a non-contact contact pressing control knob on the surface, and compared with the prior art, the non-contact contact pressing control knob touch screen provided by the invention has the advantages that a conductor touch point is not in contact with a touch display screen, the rigid conductor contactscannot scratch the display screen; the rigid conductor contacts are not in contact with the screen of the display screen, so that the rigid conductor contacts cannot be abraded, and errors cannot be generated when functions corresponding to applications running on the touch display screen are started; as the conductor contacts are not in contact with the touch display screen, the friction coefficient is small, and the rotating hand feeling is better; even if impurities such as liquid or dust enter the space between the conductor contact and the screen, the dielectric constant and the touch performance of the touch screen cannot be influenced, and due to the existence of the gap, the impurities can be quickly volatilized or fall off, and the touch screen cannot be corroded; by means of thepressing type control mode, multi-interface operation can be achieved, and better user experience is brought.

Description

technical field [0001] The invention relates to the field of touch display screens, in particular to a non-contact press knob touch screen and a function starting method thereof. Background technique [0002] Touch screens have been widely used in various electronic devices or systems such as smartphones, tablet computers, and automotive electronic systems due to their ease of operation. For the touch screens of traditional technology electronic systems, there are no knobs on the touch screen. , when users operate the application software, they need to watch the screen with their eyes, and blind operation cannot be realized; and in order to realize blind operation, people often need to use the independently set push control knob on the periphery of the touch screen to operate. It needs to be installed separately, and there is a large space for installation and operation; third, there is still a certain distance between the operator and the touch screen itself when operating,...

AI Technical Summary

Problems solved by technology

However, there are certain technical defects in this technical solution: the first is that the long-term contact between the hard touch point and the display screen will cause scratches on the display screen; The wear of the control points will lead to errors in the corresponding functions of the applications running on the startup screen; the third is that the friction coefficient increases due to contact, which affects the rotation feel; the fourth is if liquid or dust enters between the conductor contacts and the screen , it will affect its dielectric constant and affect the touch performance, because it cannot volatilize quickly, it may corrode the touch screen after a long time
