Embodiment Construction

[0016] Please refer to figure 1 , figure 1 It is a schematic structural diagram of a single-layer multi-point mutual capacitive touch screen 10 according to an embodiment of the present invention. Such as figure 1 As shown, the single-layer multi-point mutual capacitive touch screen 10 includes a substrate 100 , a flexible printed circuit board (Flexible Printed Circuit board, FPC) 102 and a control circuit 104 . In the single-layer multi-point mutual capacitive touch screen 10 , each sensing electrode is disposed on the substrate 100 and consists of a driving area and a receiving area. For example, in figure 1 Among the sensing electrodes, the slashed part is the driving area, and the dotted part is the receiving area. In other embodiments, the shapes and ranges of the driving region and the receiving region can be appropriately adjusted according to different applications, but are not limited thereto. The flexible printed circuit board 102 is disposed on one side of the...

Abstract

A driving and sensing method for a single-layer mutual capacitive multi-touch screen includes inputting a first driving signal to a plurality of touch sensing electrodes along a first direction and receiving a first sensing signal corresponding to the first driving signal along the first direction; and inputting a second driving signal to the plurality of touch sensing electrodes along a second direction and receiving a second sensing signal corresponding to the second driving signal along the second direction; wherein the second direction is substantially perpendicular to the first direction. The plurality of touch sensing electrodes are disposed in the single-layer mutual capacitive multi-touch screen, and each of the plurality of touch sensing electrodes includes at least one driving area and at least one receiving area, wherein all driving areas and receiving areas are located in a same layer of the single-layer mutual capacitive multi-touch screen.

Description

technical field [0001] The invention relates to a driving and sensing method for a single-layer multi-point mutual capacitive touch screen, in particular to a driving and sensing method which can simultaneously include the advantages of self-capacitive touch sensing and mutual capacitive touch sensing. Background technique [0002] In recent years, touch sensing technology has developed rapidly, and many consumer electronics products such as mobile phones (Mobile Phone), satellite navigation systems (GPS Navigator System), tablet computers (Tablet), personal digital assistants (PDA) and notebook computers (Laptop) All of them have built-in touch function. In the above-mentioned various electronic products, the area of ​​the original display panel is endowed with a touch-sensing function, that is, the original simple display panel is converted into a touch display panel with a touch recognition function. According to different structural designs of touch screens, they can ge...
