[0049] In another variant embodiment, such as Figure 5 As shown, when N is equal to 3, each row of the array includes not only the first electrode series 110 and the second electrode series 112 , but also the third electrode series 128 . For clarity, Figure 5 Only a single row is displayed, but not limited to. Compared with the first embodiment, in the first conductive layer C1a of this variant embodiment, the electrodes E1 located in 3*M-1 columns are electrically connected to each other to form a first electrode series 110a, and the electrodes located in 3*M columns E2 are electrically connected to each other to form a second electrode series 112a, and electrodes E3 located in 3*M-2 columns are electrically connected to each other to form a third electrode series 128, wherein the first electrode series 110a, the second electrode series 112a and the third electrode series 128 are insulated from each other. Each first wire 120 is electrically connected to each first elect...

Abstract

The invention provides a double-layer mutual-capacitance touch panel. The touch panel comprises a first conducting layer and a second conducting layer. The first conducting layer comprises multiple electrodes which are arranged in an array, wherein in each row of the array, the electrodes located in the (N*M)-1 column are mutually electrically connected into a first electrode string row, the electrodes located in the N*M column are mutually electrically connected into a second electrode string row, N is a positive integer greater than or equal to 2, and M is a positive integer greater than orequal to 1. The second conducting layer comprises M mutually insulated electrode strip groups which are sequentially arranged along the row direction of the array, wherein each electrode strip group comprises N mutually electrically connected electrode strips, and all the electrode strips in each electrode strip group extend along the column direction of the array and are overlapped with the electrodes in the corresponding column.

Description

technical field [0001] The invention relates to a mutual capacitive touch panel, in particular to a double layer mutual capacitive touch panel with a double layer electrode structure. Background technique [0002] With the rapid development of science and technology, touch display devices composed of displays and touch panels can realize touch and display functions at the same time, and have the characteristics of human-computer interaction, and have been widely used in smart phones (smart phones), satellites, etc. Navigation system (GPS navigator system), tablet computer (tablet PC) and notebook computer (laptopPC) and other electronic products. Among them, the mutual capacitive touch panel has become the mainstream touch technology used in the industry due to its advantages of high accuracy, multi-touch, high durability, and high touch resolution. [0003] The mutual capacitive touch technology mainly detects the touch event by detecting the change of coupling capacitance...
