Abstract

A touch panel includes a transparent substrate, a touch sensor layer disposed under the transparent substrate and a ground ring disposed on, above or under a black matrix. The ground ring is also disposed around the sidewall of the touch sensor layer.

Description

technical field [0001] The present invention relates to a touch panel, in particular to a touch panel with a ground ring design that can reduce the frame. Background technique [0002] A touch display is an input / output device formed by combining sensing technology and display technology, and is commonly used in electronic devices, such as portable and handheld electronic devices. [0003] The capacitive touch panel is a commonly used touch panel, which utilizes the capacitive coupling effect to detect the touch position. When a finger touches the surface of the capacitive touch panel, the capacitance at the corresponding position will be changed, so that the touch position can be detected. [0004] Figure 1A and Figure 1B A cross-sectional view and a bottom view of the touch panel are shown respectively. Figure 1A It is shown that a black matrix (black matrix, BM) 8 is disposed around the lower surface of the glass substrate 2 , and a touch sensing layer 4 is disposed ...
