Touch screen with knob on surface and method for starting function

Abstract

The invention discloses a touch screen with a knob on the surface, comprising: a touch screen and a knob arranged on the screen of the touch screen; the knob includes: a base, which can rotate around the center of the base The rotating part and the conductor contact; the base is fixed on the touch display screen; the rotating part is arranged on the base; the conductor contact is fixed on the surface of the rotating part and connected with the Touch the touch display screen described above. The invention also correspondingly discloses a function starting method of the touch screen provided with the knob on the surface. By applying the technical scheme of the present invention, the user's blind operation on the touch screen can be realized at a relatively low hardware cost.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a touch screen with knobs on the surface and a function starting method. Background technique [0002] With the advancement of electronic technology, touch screens have been widely used in various electronic devices or systems due to their ease of operation, for example, touch screens are used in smart phones, tablet computers, and vehicle electronic systems. The working principle of the touch screen is that when the user's finger with capacitive characteristics touches the touch screen, an induced current will be generated. By detecting the parameters such as the strength and direction of the current, the touch screen will be operated to activate different functions. [0003] The inventor found in the research that the touch screens of some electronic systems in the traditional technology do not have any knobs on the periphery of the touch screen. First find the volume icon...

[0003] The inventor found in the research that the touch screens of some electronic systems in the traditional technology do not have any knobs on the periphery of the touch screen. Find the volume icon in the player first, and then drag your finger to adjust the volume. This kind of touch screen will bring a little safety hazard in some scenes such as driving environment

In addition, traditional techniques such as figure 1 As shown, some knobs can also be provided on the periphery of the touch screen. Although the user can realize blind operation by sensing the positions of these knobs, the electronic system must increase its size and increase the number of components in the electronic system. The circuit design corresponding to the knob, which greatly increases the hardware cost of the electronic system
