PROJECTIVE-CAPACITANCE TOUCH PANEL AND METHOD OF ITS MANUFACTURING Russian patent published in 2019 - IPC G06F3/44 

FIELD: physics.

SUBSTANCE: invention relates to projective-capacitance touch panels. Technical result is achieved by the fact that in the projection-capacitive touch panel, the contact or contactless approach coordinates of the input object are determined based on the change in electrical capacitance, accumulated in this panel, measured by controller either in form of same electric capacity, or in form of related other electrophysical or time parameters, wherein controller is able to recognize two or more touch or approach of input objects, matrix consists of discrete, separate from each other, thick-film capacitors in the form of pairs of two films of arbitrary shape, connected to the controller through an analogue-to-digital converter, which is part of the controller.

EFFECT: technical result consists in reduced thickness and high transparency of the projection-capacitive touch panel.
