Problems solved by technology

However, since there are many opaque metal wires in the frame area of ​​a general touch screen, these light-transmitting patterns must be placed in the frame area to avoid the area with metal wires, thus limiting the variability in design.
In addition, with the slim border design of the touch screen, it is even more difficult to avoid metal wires in the border area to set the light-transmitting pattern

Abstract

A touch panel including a touch region, a border region, a signal transmission device, and a light transmission pattern is provided. The border region is disposed on at least one side of the touch region. The signal transmission device is disposed in the border region. The light transmission pattern is disposed in the border region. The light transmission pattern partially overlaps the signal transmission device along a vertical projection direction. The signal transmission device includes at least one transparent conducting line. The transparent conducting line overlaps partial the light transmission pattern in the vertical projection direction.

Description

technical field [0001] The invention relates to a touch screen, in particular to a touch screen in which wires in a frame area partially overlap with light-transmitting patterns. Background technique [0002] Due to the characteristics of human-computer interaction and diversified design, the touch screen is widely used in the external input interface of the instrument. In recent years, as the application of consumer electronic products has become more and more extensive, more and more products are applied by combining the touch function with the display, such as mobile phones, GPS navigator systems, and tablet computers. (tablet PC), and notebook computer (laptop PC). In the aforementioned consumer electronic products, in addition to the main display touch area on the touch screen, the frame area of ​​the touch screen is also used for other functions, such as setting decorative patterns (such as special symbols or trademarks, etc.), and patterns set to represent functiona...
