Problems solved by technology

However, if an Electrostatic Discharge (ESD) phenomenon occurs, adjacent touch electrode patterns and dummy electrode patterns may be electrically connected to each other due to electrostatic damage, which makes the touch electrode pattern equivalently The area becomes larger, resulting in abnormal touch signals

Embodiment Construction

[0029] When read in conjunction with the drawings, the embodiments of the present invention can be better understood according to the following detailed description. It should be emphasized that according to the standard practice in the industry, the features in the figure are not drawn to scale. In fact, each feature can be arbitrarily enlarged or reduced. In addition, unless the direct contact is specifically noted below, other features can be added between features.

[0030] image 3 It is a top view of the touch panel according to the first embodiment. Please refer to image 3 The substrate 210 of the touch panel 200 has a display area 210a and a non-display area 210b. The transparent conductive layer of the touch panel 200 is formed on the substrate 210 and includes a plurality of electrode blocks. These electrode blocks can be divided into first electrode blocks 230 arranged in an array shape in the display area 210a, and second electrode blocks 240 arranged around the fi...

Abstract

The invention discloses a touch panel and an electronic apparatus. The touch panel comprises a substrate, a plurality of first electrode blocks and a plurality of second electrode blocks. The substrate has a display region and a non display region. The first electrode blocks and the second electrode blocks are formed on the substrate, and the second electrode blocks are arranged around the first electrode blocks. Each first electrode block is completely arranged in the display region, and at least one part of each second electrode block is located in the non display region. Each first electrode block comprises a first touch electrode pattern and a first virtual electrode pattern. Each of the second electrode blocks comprises a second touch electrode pattern and a second region; at least one part of the second region comprises at least one second virtual electrode pattern; and the area of the second virtual electrode pattern is smaller than that of the first virtual electrode pattern. According to the touch panel and the electronic apparatus, the electrostatic discharge probability can be reduced.

Description

Technical field [0001] The present invention relates to a touch panel, and in particular to a touch panel with different virtual electrode patterns designed in a display area and a non-display area, and an electronic device using the touch panel. Background technique [0002] A general touch panel has multiple touch electrode patterns. For a capacitive touch panel, the area of ​​the touch electrode pattern will affect the corresponding capacitance value. In some applications, dummy electrode patterns are arranged between adjacent touch electrode patterns to avoid visual effects caused by gaps between the touch electrode patterns. Generally, the virtual touch electrode pattern and the touch electrode pattern are not electrically connected. However, if an electrostatic discharge (ESD) phenomenon occurs, the adjacent touch electrode pattern and the dummy electrode pattern may be short-circuited and electrically connected to each other due to electrostatic damage, which makes the to...
