Embodiment Construction

[0056] Figure 1A It is a three-dimensional schematic diagram of a touch display device according to an embodiment of the present invention.

[0057] Please refer to Figure 1A , the display device 1 includes a display panel 10 , a touch device 20 and a transparent cover 30 stacked in sequence. In this embodiment, the display panel 10 and the touch device 20 are bonded by the first optical glue OG1, and the touch device 20 and the transparent cover 30 are bonded by the second optical glue OG2.

[0058] The display panel 10 is a Liquid crystal display panel, a micro-LED display panel, an OLED display panel or other types of display panels. When the display panel 10 is a liquid crystal display panel, the display device 1 further includes a backlight module located on the back of the display panel 10 , but the present invention is not limited thereto.

[0059] The touch device 20 includes a substrate 200 and a plurality of touch units TU on the substrate 200 . The substrate 200...

Abstract

A touch device comprises a substrate and a plurality of touch units. Each touch unit comprises a first conductive layer, a coating layer and a second conductive layer. The first conductive layer comprises a first touch line, a first repair line segment and a first dummy electrode. The first touch line is located on one side of the first repair line segment. The first dummy electrode is located on the other side of the first repair line segment. The coating layer is located on the first conductive layer. The second conductive layer is located on the coating layer and comprises a second touch line, a first bridging structure and a second dummy electrode. The second touch line overlaps the first touch line and the first repair line segment. The first bridge structure overlaps the first touch line and the first repair line segment. The second dummy electrodes are located on the outer sides of the second touch lines.

Description

technical field [0001] The present invention relates to a touch device, and in particular to a touch device with a repair line segment. Background technique [0002] With the development of science and technology, the appearance rate of touch devices in the market is gradually increasing, and various related technologies are emerging in an endless stream. In some electronic devices, such as mobile phones, tablet computers, smart watches, etc., a touch device is often combined with a display panel to obtain a touch display device that is easy to use. [0003] Generally speaking, a touch panel with touch function is additionally pasted on the outside of the display panel, so as to integrate the touch function and display function into the same device. At present, the touch panel includes mutually interleaved transmit signal lines (Transmit, TX) and receive signal lines (Receive, RX), and there is a capacitor where the transmit signal lines overlap with the receive signal line...
