Benefits of technology

[0004]The invention provides a touch panel that helps to reduce the visibility of the members to improve applicability of the touch panel.
[0022]Based on the above, according to the embodiments of the invention, the touch panel is disposed with the island insulator covering the bridge line, and the contour of the island insulator has a non-rectangular shape. In this way, the reflective light generated in accordance with the contour of the island insulator can be emitted towards diverging directions, so as to help reducing the visibility of the island insulator and the members covered by the island insulator. Accordingly, when being applied to the display panel or the display device, the touch panel according to the embodiments of the invention facilitates to maintain an ideal displaying quality.

Problems solved by technology

In particular, when the touch panel is applied to a display panel or a display device, the visibility of the bridge line that can reduce a displaying quality is expected to be as low as possible.

Embodiment Construction

[0035]Reference will now be made in detail to the present preferred embodiments of the disclosure, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.

[0036]FIG. 1 is a top view of a touch panel in an embodiment of the invention. In FIG. 1, a touch panel 100 includes a substrate 110, a plurality of sensing electrodes 120, a plurality of bridge lines 130 and a plurality of connection lines 140. The sensing electrodes 120 are disposed on the substrate 110 in parallel and arranged in an array. In this embodiment, each of the sensing electrodes 120 is substantially in shape of rhombus. However, in other embodiments, shape, size and layout of each of the sensing electrodes 120 may be adjusted based on design requirements. The bridge lines 130 and the connection lines 140 are disposed on the substrate 110, and configured to connect the sensing electrode...

Abstract

A touch panel including a substrate, a plurality of sensing electrodes, a bridge line, a connection line and an island insulator is provided. The sensing electrodes are disposed on the substrate in parallel. The bridge line is disposed on the substrate and connected between two of the sensing electrodes. The connection line is disposed on the substrate and connected between another two of the sensing electrodes. The bridge line intersects the connection line. The island insulator is disposed on the substrate and covers the bridge line. The bridge line is completely encapsulated between the island insulator and the substrate. The island insulator includes a central portion and a distal portion extended from the central portion. A width of the distal portion is gradually reduced outwardly from the central portion.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefit of Taiwan application serial no. 108114433, filed on Apr. 25, 2019. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.BACKGROUND OF THE INVENTION1. Field of the Invention[0002]The invention relates to an electronic device, and more particularly, to a touch panel.2. Description of Related Art[0003]Touch panels have been widely applied to products in various fields to provide intuitive and convenient input operation interfaces. In many products, the touch panel realizes a touch sensing function by a serial electrode array in which a plurality of horizontal electrode strings intersecting a plurality of vertical electrode strings are arranged. In addition, a bridging structure (e.g., a bridge line and an insulation layer for separate the bridge line from another string) may be used at intersections between the hori...
