Problems solved by technology

[0005] When the user's finger is not in good contact with the touch screen, the capacitance value between the touch node and the wire changes very little, even close to 0, resulting in inaccurate detection of the touch position, or even failure to detect the touch position

Abstract

The invention discloses a device and method for improving a touch effect of a touch control device. The device comprises a touch screen and a pressure sensor film. The device is characterized in that the pressure sensor film is arranged on the back surface of the touch screen, an intermediate plate is arranged on the back surface of the pressure sensor film, and an appropriate gap which is used for straining pressure is formed between the pressure sensor film and the intermediate plate; meanwhile, the device also has the function that the pressure position is calculated through the pressure sensor film conveniently. According to the device and the method, the problems of inaccurate touch position detection even no output between fingers and the touch screen under the systematic non-good touch state can be solved.

Description

technical field [0001] The invention belongs to the technical field of touch screens, in particular to an electronic device with a touch screen. Background technique [0002] Many electronic devices are now equipped with capacitive touch screens. [0003] The touch technology of the projected capacitive panel The projected capacitive touch screen is to etch different ITO conductive line modules on two layers of ITO conductive glass coating. The patterns etched on the two modules are perpendicular to each other, and they can be regarded as sliders that change continuously in the X and Y directions. Since the X and Y structures are on different surfaces, their intersections form a capacitor node. One slider can be used as a drive line, and the other slider can be used as a sense line. When the current passes through one wire in the drive line, if there is a signal of capacitance change outside, it will cause the change of the capacitance node on the other layer of wire. Th...
