Problems solved by technology

[0005] However, in the prior art, such as image 3 As shown, the touch panel in the dual-sensing mode is achieved by arranging the capacitive sensing circuit 920 and the electromagnetic sensing circuit 900 above and below a liquid crystal display module (Liquid Crystal Display Module, LCM) 930 respectively to achieve both electrical and electronic functions. The functions of magnetic induction and capacitive induction, but such a design will increase the overall thickness of the display and increase the production cost

Embodiment Construction

[0101] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0102] refer to Figure 4 and Figure 5 , which is a first preferred embodiment of the dual-mode touch-sensitive display 100 of the present invention, the display 100 is a liquid crystal display and has both capacitive-sensing touch functions and electromagnetic-inductive touch functions. In this embodiment, the display 100 includes at least a touch sensing module 10, a display module 20 for displaying images, and a backlight (black light) 30 for providing a light source. The display module 20 is a Liquid Crystal Display Module (LCM).

[0103] refer to Figure 5 and Figure 6 , the touch sensing module 10 at least includes several first wires 1, several second wires 2, a switch unit 3, a sensing unit 4, and an insulating layer 5 (insulating layer, such as Figure 6 shown, may also be a dielectric layer). The first wire 1 is a metal wire and the ...

Abstract

The present invention relates to a dual mode touch sensing module and a display. The display includes a display module used for displaying screens, and a touch sensing module disposed at the display module. The touch sensing module includes a plurality of first conductors, a plurality of second conductors, an insulating layer and a sensing unit, the first conductors are mutually arranged side by side and extend in a first direction, the second are mutually arranged side by side and extend in a second direction intersecting the first direction, the second conductors and the first conductors are mutually interlaced but not intersected, the interlacing area is spaced with the insulating layer, and the sensing unit is coupled to the first conductors and the second conductors for sensing the sensing signals on the first conductors and the second conductors.

Description

technical field [0001] The invention relates to a display, in particular to a dual-mode touch sensing module and a dual-mode touch sensing display. Background technique [0002] A touch screen panel is a panel that can be touched by the user through a finger or a stylus. The user can use the touch panel to write characters, draw pictures, or borrow Commands are executed by icons on the screen, and common touch panels are divided into three types: electromagnetic induction mode, capacitive induction mode, and dual induction mode combining electromagnetic induction mode and capacitive induction mode. [0003] refer to figure 1 , is the existing electromagnetic induction touch sensing circuit 900, which includes several first sensing lines 911, several second sensing lines 912 intersecting with the first sensing lines 911, and two respectively coupled to the first sensing lines The induction circuit 913 of the line 911 and the second induction line 912, the induction circuit ...
