Embodiment Construction
[0036] As mentioned in the background technology section, the pressure-sensing touch screen in the prior art can only sense the pressure change on the surface of the pressure-sensing touch screen, but cannot continuously detect the pressure on the surface of the pressure-sensing touch screen. The application is relatively limited, which limits the pressure Development of inductive touch screens.
[0037] In view of this, an embodiment of the present invention provides a touch screen, including: at least one first pressure-sensing structure, and the first pressure-sensing structure includes:
[0038] a first strain sensor located in the first region;
[0039] The second strain sensor located in the second area, wherein the second area is located around the first area, and the distance between the boundary line of the second area and the first area and the edge of the touch screen is less than default value;
[0040] A first power supply, one end of the first power supply is e...

The embodiment of the present invention discloses a touch screen, including a first strain sensor located in a first area, a second strain sensor located in a second area, a first power supply and a first voltage detector, wherein the second area is located in the first area Around, the first power supply is used to provide working voltage for the first strain sensor and the second strain sensor, one end of the first voltage detector is connected to the first preset voltage, and one end is electrically connected to the common end of the first strain sensor and the second strain sensor , used to detect the voltage of the common terminal of the first strain sensor and the second strain sensor. The touch screen provided by the present invention can not only detect the pressure change on the surface of the touch screen, but also continuously detect the pressure on the surface of the touch screen, which solves the problem that the pressure-sensitive touch screen in the prior art can only detect the pressure change on the surface of the touch screen, but cannot continuously detect the pressure on the surface of the touch screen The size problem expands the application scope of the pressure-sensitive touch screen and promotes the development of the pressure-sensitive touch screen.
Description
technical field [0001] The invention relates to the technical field of touch, in particular to a touch screen. Background technique [0002] With the development of electronic technology, the application of touch screen is more and more extensive, and it has gradually become an indispensable information interaction medium for people's daily life. The touch screen in the prior art includes: a touch-sensitive touch screen and a pressure-sensitive touch screen, wherein the pressure-sensitive touch screen mainly adopts the piezoelectric pressure-sensing principle, that is, the pressure-sensitive touch screen is made of a piezoelectric material, and when the piezoelectric material is under pressure, its The principle that the resistance will change is to detect the pressure on the pressure-sensitive touch screen by detecting the resistance of the piezoelectric material or detecting the voltage of the piezoelectric material under a constant current. [0003] However, since the ch...
