Embodiment Construction

[0058] figure 1is a schematic diagram of a touch panel according to an embodiment of the present invention. Please refer to figure 1 , the touch panel 100 includes a substrate 110 and a plurality of touch sensing units 120 . A plurality of touch sensing units 120 are sequentially arranged on the substrate 110 , and each touch sensing unit 120 includes a first electrode group 122 and a second electrode group 124 . The first electrode group 122 includes a plurality of first electrodes 1222 arranged sequentially along a first direction D1 and separated from each other by a first gap G1 . The second electrode group 124 is located beside the first electrode group 122 and includes a plurality of second electrodes 1242 . The second electrodes 1242 are arranged sequentially along the first direction D1 and separated from each other by a second gap G2. One of the width W of each second electrode 1242 and the width W of each first electrode 1222 increases sequentially along the firs...

Abstract

A touch panel including a substrate and touch sensitive units is provided. Each touch sensitive unit includes a first electrode set and a second electrode set. Each first electrode set includes first electrodes separated by a first space between one another. Each second electrode set includes second electrodes separated by a second space between one another. One of a width of each second electrode and a width of each first electrode is increased along a first direction, and the other one is decreased along the first direction, wherein at least one of the second space is not aligned to at least one of the first space so that an extended trajectory of the at least one of the second space passes through one of the first electrodes. Two adjacent first electrodes are electrically independent and two adjacent second electrodes are electrically independent.

Description

technical field [0001] The invention relates to touch panel technology, in particular to a touch panel with multi-touch function. Background technique [0002] In today's information society, many information products have changed from traditional input devices such as keyboards or mice to use touch sensing panels as input devices, among which touch display devices with both touch and display functions are more It is one of the most popular products nowadays. [0003] Currently, touch panels can be roughly classified into resistive, capacitive, infrared and ultrasonic touch panels, among which resistive touch panels and capacitive touch panels are the most common products. As far as the capacitive touch panel is concerned, the multi-touch feature provides a more user-friendly operation mode, so that the capacitive touch panel is gradually favored by the market. However, in order to achieve the multi-touch function, sometimes it is necessary to increase the number of channe...
