Touch screen device with mistaken touch prevention function

Abstract

The invention relates to the technical field of touch screens, in particular to a touch screen device with a mistaken touch prevention function. The device comprises a shell, screen glass, a polarizing plate, a touch panel and a substrate; the substrate is fixedly mounted at the bottom of the shell, and the touch prevention plate is driven by a driving device to do linear motion in a rectangular placement groove; the driving device comprises a driving plate, a clamping strip, a pressing block and a push rod; cavities are formed in the two ends of the outer wall of the shell, vertical plates are movably installed in the cavities, the upper end faces of the vertical plates are fixedly connected with L-shaped baffles, a plurality of S-shaped elastic pieces are fixedly arranged on the inner wall faces of the vertical plates, and the push rod is fixedly connected with the vertical plates. By utilizing the repulsion effect between a first magnetic block and a second magnetic block with the same name, the driving plate can drive an anti-touch plate to extend out of the first movable groove to the outer side and be located at the upper end of the edge of the screen glass under the condition of not bearing an external force, fingers of a user are prevented from touching a screen, and therefore the mistaken touch prevention effect is achieved.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a touch screen device with an anti-mistouch function. Background technique [0002] Capacitive touch screen technology uses the current induction of the human body to work. The capacitive touch screen is a four-layer composite glass screen. The inner surface and interlayer of the glass screen are each coated with a layer of ITO. The outermost layer is a thin layer of silica glass protective layer. The interlayer ITO coating is used as the working surface. Four electrodes, the inner ITO is the shielding layer to ensure a good working environment. [0003] At present, with the development of mobile terminals such as mobile phones, manufacturers and users are increasingly pursuing narrow bezels, or even no bezels. Narrow bezel or no bezel certainly brings visual impact to the user, but it also brings a problem. When the user holds the mobile phone, it is easy to touch the edge of the ...

Problems solved by technology

Narrow bezel or no bezel certainly brings visual impact to users, but it also brings a problem. When users hold the mobile phone, it is easy to touch the edge of the mobile phone screen by mistake, causing many misoperations and reducing user experience.
