Embodiment Construction

[0043] see Figure 1 to Figure 3 , which shows a class of embodiments of the present invention, which mainly relates to a touch array 1, and the touch array 1 can be used to simultaneously detect signals of a finger and an electromagnetic pen.

[0044] exist Figure 1 to Figure 3 The shown touch array 1 includes a capacitive coupling touch array for detecting finger touch signals and an electromagnetic induction array for detecting electromagnetic pen signals. Certainly, both the capacitive coupling touch array and the electromagnetic induction array for detecting the electromagnetic pen signal are attached on the surface of the same substrate 10 ; and the capacitive coupling touch array and the electromagnetic induction array are insulated from each other.

[0045] In this aforementioned Chinese patent application with publication number CN102163112A, since the capacitive coupling touch array and the electromagnetic induction array are composed of the same array, there is no...

Abstract

The invention provides a touch-control array, a touch-control sensor, a touch-control display screen and a touch-control device. The touch-control array comprises a substrate, a capacitive coupling touch-control array and an electromagnetic induction array, wherein the capacitive coupling touch-control array and the electromagnetic induction array are arranged in a manner of being insulated from each other; the capacitive coupling touch-control array comprises a first direction capacitive conductor group and a second direction capacitive conductor group; the electromagnetic induction array comprises a first direction induction lead group and a second direction induction lead group; the first direction capacitive conductor group and the first direction induction lead group are arranged on a first surface of the substrate, and the second direction capacitive conductor group and the second direction induction lead group are arranged on a second surface of the substrate; or, the first direction capacitive conductor group and the second direction induction lead group are arranged on the first surface of the substrate, and the second direction capacitive conductor group and the first induction lead group are arranged on the second surface of the substrate. The touch-control array can simultaneously identify signals of a finger and an electromagnetic pen at any time.

Description

technical field [0001] The invention relates to touch technology, in particular to a touch array, a touch sensor, a touch display screen and a dual-mode touch device capable of both capacitive and inductive touch. Background technique [0002] Capacitive touch technology is mainly used in products that are directly touched by fingers, such as mobile phones, computers, video playback terminals, etc. Inductive touch technology is mainly used in products that use pens that emit electromagnetic signals to write, such as electronic whiteboards, children's learning machines, etc. [0003] The capacitive touch sensor mainly adopts a densely arranged array structure. When a finger touches the array structure, it detects the high-speed current or voltage scanning signal conducted by the finger to realize the positioning of the touch point. The advantage of the capacitive touch sensor is that the sensitivity is higher than that of the resistive film touch sensor, and it can be direct...
