Description

Touch pen device with simple structure

This creation relates to a stylus device, especially a stylus device with a simple structure.

In recent years, due to the development of touch screens, it has had a significant impact on the operation of electronic products; users no longer need a keyboard or mouse to input commands, and can directly draw or write on the touch screen. Among various touch screens, capacitive touch screens are widely used in electronic products, such as mobile phones and tablet computers, because they are more durable. In order to improve the user's operation convenience, most touch panels can be equipped with a stylus for click input or writing or drawing on the touch panel. Therefore, the stylus is very important; however, the disadvantage of the related-art stylus is that the structure of the related-art signal transmission line connected to the tip of the related-art stylus is very complicated.

The structure of the related-art signal transmission line is as follows: a copper wire is covered by a first insulating layer, the first insulating layer is covered by a ground layer, the ground layer is covered by a second insulating layer, and the second insulation The layer is covered by a signal transmission layer. The copper wire and the signal transmission layer respectively transmit different stylus signals, and when the two different stylus signal transmissions are very close to the stylus tip, the two different stylus signals cannot interfere with each other This is why there must be the ground layer between the copper wire and the signal transmission layer. The ground layer allows the two different stylus signals to be transmitted on the copper wire and the signal transmission layer without interfering with each other. The copper wire, the ground layer, and the signal transmission layer are all metals, so the first insulating layer and the second insulating layer are disposed between the copper wire, the ground layer, and the signal transmission layer.
