Description

Touch panel

The present invention relates to a touch panel, and more particularly to a touch panel, wherein the touch function is realized by a magnetic force.

According to the display panel with touch function, if the touch module is located above the display panel, the touch module must be made of transparent material such as glass or ITO (Indium Tin Oxside). The display screen of the panel is not blocked by the touch module. However, if the display panel is a reflective display panel--based on the ambient light source display screen, although the touch module is made of a transparent material, the brightness of the touch panel is still attenuated by the touch module and affects the display effect. Therefore, the reflective display panel is generally placed on top of the touch module.

In order to avoid damage to the display panel located above the touch module during the touch input operation, the touch module generally adopts a capacitive, optical and other non-contact touch mechanism. However, whether it is implemented by a transparent material such as glass, ITO (Indium Tin Oxside) or a non-contact touch mechanism such as a capacitive or optical type, the cost is high and the control is high. The shortcomings of the circuit complexity.

In order to solve the shortcomings of the above-mentioned reflective display with touch function, the present invention proposes a novel display structure, which uses a magnetic force to implement a touch function, in addition to the problem of no brightness degradation, and a cheaper plastic and Generally, metal touch sensing modules are used to reduce manufacturing costs.

An object of the present invention is to disclose a touch panel whose touch function is realized by magnetic force.

Another object of the present invention is to provide a touch panel that can be used to manufacture touch sensing modules in less expensive plastics and general metals, thereby reducing manufacturing costs.

In order to achieve the above object, a touch panel is proposed, which uses a magnetic stylus as an input means. The touch panel has a display panel having a display surface and a joint surface. Located below the display surface; and a sensing assembly, located under the display panel, having a first conductor layer, a second conductor layer, and a plurality of insulating spacers, the first conductor layer and the bonding surface Laying, and the insulating spacer is disposed between the first conductor layer and the second conductor layer to divide the first conductor layer into a plurality of first conductor segments, and dividing the second conductor layer into plural And a second conductor segment, wherein the second conductor segment is bent upward to be electrically connected to a first conductor segment when subjected to the magnetic force of the magnetic stylus.

The detailed description of the drawings and the preferred embodiments are set forth in the accompanying drawings.

Please refer to FIG. 1 , which is a cross-sectional view showing a touch structure of a preferred embodiment of the touch panel of the present invention. The touch panel has an electronic paper panel 101, a first conductor layer 102, a second conductor layer 103, and a plurality of insulating spacers 104.

The electronic paper panel 101 has a display surface and a joint surface located below the display surface, and receives an image information according to an electronic paper input port (not shown) and displays it on the display surface. on. The electronic paper panel 101 is, for example but not limited to, an electrophoretic display, a microelectromechanical display, a cholesteric liquid crystal display, an electrowetting display or a liquid crystal display, and the electronic paper input port is preferably a universal serial bus (USB) port.

The first conductive layer 102, the second conductive layer 103, and the insulating spacer 104 are used to form a sensing assembly, which is preferably a resistive touch sensing module, wherein the first The conductor layer 102 is bonded to the bonding surface of the electronic paper panel 101, and the preferred composition of the first conductor layer 102 is a general metal such as copper, aluminum or the like.

There is a gap between the second conductor layer 103 and the first conductor layer 102, and a preferred composition of the second conductor layer 103 is a general metal such as copper, aluminum or the like.

The insulating spacers 104 are used to isolate the second conductor layer 103 from the first conductor layer 102 to generate the gap, and divide the first conductor layer 102 into a plurality of first conductor segments, and the first The two conductor layer 103 is divided into a plurality of second conductor segments. The preferred composition of the insulating spacers 104 is plastic.

Please refer to FIG. 2 , which illustrates the touch principle of the touch panel of the present invention. As shown in FIG. 2, a magnetic stylus 200, when contacting the electronic paper panel 101, generates a magnetic force to bend a second conductor segment to be electrically contacted with a first conductor segment. A controller (not shown) can generate a corresponding touch position signal after sensing the electrical contact.

When the magnetic stylus 200 is away from the electronic paper panel 101, the second conductor segment returns to its original state due to the action of gravity and elastic restoring force.

The invention has the following characteristics due to its novel design:

1. The touch module of the present invention is placed under the display panel, so the display brightness of the display panel is not affected.

2. The touch function of the present invention is realized by the action of magnetic force, and does not need to press the display panel, so the display panel is not damaged.

3. The touch module of the present invention can be realized by plastic and general metal, and does not need to use transparent materials such as expensive glass and ITO (Indium Tin Oxside), thereby reducing manufacturing cost.

In summary, the touch panel of the present invention can provide a touch function without damaging the display panel, and thus the present invention has improved the lack of the conventional reflective touch panel. .

The disclosure of the present invention is a preferred embodiment. Any change or modification of the present invention originating from the technical idea of the present invention and being easily inferred by those skilled in the art will not deviate from the scope of patent rights of the present invention.

In summary, this case, regardless of its purpose, means and efficacy, is showing its technical characteristics that are different from the conventional ones, and its first invention is practical and practical, and it is also in compliance with the patent requirements of the invention. I will be granted a patent at an early date.
