Electrostatic capacitive touch-sensitive panel for display device

Abstract

An electrostatic capacitive touch-sensitive panel has an active area; a touch electrode forming area; a routing wire forming area disposed; a plurality of first touch electrode lines disposed in the active area, with both ends extending to a plurality of electrode pattern extension regions; a plurality of second touch electrode lines disposed in the active area to cross the first direction so as to cross the first touch electrode lines without contact; a plurality of first routing wires connected to the plurality of first touch electrode lines, respectively; and a plurality of second routing wires connected to the plurality of second touch electrode lines, respectively. Each of the second touch electrode lines includes a plurality of second touch electrode patterns and a plurality of second connecting portions connecting neighboring second touch electrode patterns. The second touch electrode pattern has an asymmetrical portion.

Description

technical field [0001] This document relates to a touch panel, and more particularly, to an electrostatic capacitive type touch panel providing enhanced touch performance by improving touch accuracy on an edge area of ​​a touch panel having a narrow bezel. Background technique [0002] Recently, various input devices such as keyboards, mice, trackballs, joysticks, and digitizers have been used to constitute interfaces between users and home appliances or various information communication devices. However, such input devices as keyboards, mice, etc. require users to learn to use them and take up space, thus making it difficult to improve the comprehensiveness of products. Therefore, there is an increasing demand for input devices that are convenient, easy to use, and reduce erroneous operations. In response to this demand, touch screen panels are provided that allow users to input information by directly touching the screen with their hands or pens. [0003] The touch panel...

Problems solved by technology

[0016] However, image 3 The touch panel with a narrow bezel needs to greatly reduce the distance between the edge of the active area and the edge of the touch electrode formation area TA, and therefore, the time constant increases due to the increase in the distance between the touch electrode and the wiring

In addition, the extensions of the touch electrode lines TS1 to TS5 and RS1 to RS6 outside the active area AA are reduced, resulting in low touch accuracy on the edge area
