touch screen input device

Abstract

A touch screen input apparatus includes a first electrode layer, a second electrode layer, and a controller. The first electrode layer is configured to perform sensing in a first direction, and provided with first electrode patterns which are formed on the top surface of a substrate. The second electrode layer is configured to perform sensing in a second direction, provided under the first electrode layer, and provided with second electrode patterns which are formed on the top surface of a substrate such that the second electrode patterns overlap the first electrode patterns through a surface on which the first electrode patterns are not formed, and which are spaced apart from each other by predetermined intervals. The control unit is configured to control the electrode patterns other than electrodes which are used to measure capacitance in a ground state.

Description

technical field [0001] The invention relates to a touch screen input device, in particular to a touch screen input device which improves the electrode pattern structure, reduces noise and reduces cost at the same time. Background technique [0002] Generally speaking, a touch screen is a screen equipped with a special input device, and its position can be input through the device when it is touched by hand. That is to say, without using a keyboard, you can grasp the position by touching the text or specific position on the screen (screen) with your hands or small tools, and perform specific processing through the stored program, and the input data can be directly received on the screen. [0003] Such as figure 1 As shown, the touch screen of the aforementioned capacitance mode includes: a touch screen (capacitance sensor) 20, which can detect the contact between the window (window) 10 of transparent material and the human body; The electrical signal and the coordinates inp...
