Abstract

The invention provides a pressure sensing touch control module, comprising a touch control sensing layer and a conductive layer; the touch control sensing layer detects a touch control position signal at a first stage; the touch control sensing layer matches with the conductive layer at a second stage; two pole plates of a capacitor are formed through the touch control sensing layer and the conductive layer; pressure signals are detected according to the capacitance value change conditions generated according to the distance changes between the two pole plates. According to the module of the invention, the problems that the pressure sensing touch control module in the prior art collects the touch control position signals and the touch control pressure signals respectively, the cost is high and the preparation process is complex are solved; the pressure sensing touch control module of the invention detects the touch control position signals and the touch control pressure signals by a same IC at separate time.

Description

【Technical field】 [0001] The invention relates to the field of touch modules, in particular to a pressure-sensing touch module. 【Background technique】 [0002] At present, most touch panels on the market only have touch position detection. With the diversification of functions of electronic products, more and more usage scenarios need to detect the force at the touch point to complete more product functions. , to improve user experience, and in the existing capacitive pressure touch structure, an air layer is required to separate the two electrode structures. Because the resistance of the air layer is small, it can produce large deformation, but if the air layer exists Above the display, there may be a problem that the Newton ring affects the visual effect, so the pressure-sensing structure must be placed below the display, and this setting makes the pressure-sensing structure and the touch surface far away, and there are many other laminated structures in the middle to disp...
