Abstract

The invention discloses a capacitive touch screen. A conductive groove is arranged in the surface of the touch screen, scratching of conductive materials in the use process of the capacitive touch screen is reduced, due to the groove structure, covering areas of the conductive materials are reduced, resistance is reduced, and production cost is reduced.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a capacitive touch screen. Background technique [0002] Touch screen, also known as "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. When the graphic buttons on the screen are touched, the tactile feedback system on the screen can drive various connecting devices according to the pre-programmed program, which can be used to replace the mechanical button panel, and create vivid audio-visual effects through the LCD screen. According to the working principle of the touch screen and the medium for transmitting information, the touch screen can be divided into resistive type, capacitive sensing type, infrared type and surface acoustic wave type, among which the capacitive touch screen is currently the most widely used one. [0003] The capacitive touch screen works by using the current induction of the human ...
