Three-dimensional touch panel

Abstract

The invention provides a three-dimensional touch panel. The three-dimensional touch panel comprises an insulation dielectric layer, a touch electrode layer and a pressure-sensitive electrode layer, wherein the touch electrode layer and the pressure-sensitive electrode layer are respectively positioned at two opposite sides of the insulation dielectric layer; the touch electrode layer comprises multiple sets of insulated and staggered touch electrodes and is used for detecting the position of a touch signal; the pressure-sensitive electrode layer comprises at least one pressure-sensitive electrode correspondingly arranged with at least one part of the touch electrodes and is used for detecting the pressure of the touch signal; the touch electrode correspondingly arranged with the pressure-sensitive electrode is also used for performing temperature compensation of the pressure-sensitive electrode; and the temperature compensation manner includes a positive and negative temperature coefficient material series manner, a value reduction manner and a Wheatstone bridge manner. The three-dimensional touch panel provided by the invention has the advantages of being high in detection precision, light, thin and the like.

Description

【Technical field】 [0001] The invention relates to the field of touch control, in particular to the field of three-dimensional touch control. 【Background technique】 [0002] Touch panels are widely used in various consumer electronic devices, such as portable electronic products such as smart phones, tablet computers, cameras, e-books, and MP3 players, or display screens for operating control devices. In recent years, a three-dimensional touch panel with both plane position detection and pressure pressure detection has attracted extensive attention. [0003] The currently commonly used 3D touch panels usually have a touch electrode layer and a double-layer pressure-sensitive electrode layer. Among them, the touch electrode layer is used to detect the plane position of the touch signal, usually a capacitive touch electrode, which uses the current induction of the human body to work: establish a plane two-dimensional coordinate system (X, Y) in the touch area, and There are t...
