Embodiment Construction

[0050] The present invention is eager to improve and innovate, and after years of painstaking research, a touch panel has been developed, which can break through the bottleneck of the existing narrow frame design. A plurality of implementations of the present invention will be disclosed below with the accompanying drawings. For the sake of clarity, many practical details will be described together in the following description. However, it should be understood that these practical details are not used to limit the present invention. That is to say, in the embodiments of the present invention, some conventionally used structures and components will be simply and schematically shown in the drawings Of.

[0051] see figure 2, is a bottom view of the touch panel of the present invention. The touch panel includes a touch sensing layer 20 , a peripheral circuit area 22 and a bonding area 24 . The touch panel further includes a substrate 26. For example, the material of the hard s...

Abstract

The present invention provides a touch panel, wherein a plurality of wires in a peripheral circuit area are respectively electrically connected to a plurality of first axial sensing electrode units of a touch sensing layer; A conductive pad is electrically connected to these traces, and a plurality of second axial sensing electrode units of the touch sensing layer is electrically connected to a plurality of second conductive pads in the bonding area. The conductive pads and the second conductive pads can not only reduce the number of wires, but also directly make the pin conductive pads in the bonding area, which can effectively save design space and achieve the effect of extremely narrow borders.

Description

technical field [0001] The present invention relates to a touch panel, which refers to a touch panel with a slim boarder. Background technique [0002] In recent years, touch technology has been widely used in various multimedia electronic products, especially portable mobile products such as smart phones, e-books or tablet computers. Using touch technology as an input method can effectively replace the existing input methods such as keyboard or mouse. In addition to improving convenience, and because of the intuitiveness of operation, touch input technology has become a very popular human-machine interface and multimedia interactive way. [0003] With the rapid development of touch technology, the quality of touch devices continues to improve, especially in light of the current trend of touch devices requiring light, thin, and large screens. How to increase the screen utilization of touch devices is very important. One of the topics, for example, a smart phone with a narr...
