Description

Stylus and electronic device

The present invention relates to a stylus and an electronic device, and more particularly to a stylus and an electronic device having a plurality of types of pens.

With the rapid development of technology, manufacturers of electronic devices such as notebook computers, mobile phones, and portable multimedia players have used touch panels to replace traditional keyboards as a new generation of input interfaces. In more detail, the current touch panels can be roughly classified into a capacitive touch panel and a resistive touch panel. Taking the iPhone as an example, the iPhone uses a capacitive touch panel as an input interface, so the user can perform input operations such as inputting text or selecting a menu with only a finger.

However, in order to match the user's finger, the various icons displayed on the screen must be of a considerable size to prevent the user from making a mistake in operation. Secondly, during the use of the capacitive touch panel, the user's fingers often obscure parts of the screen. In addition, the traditional stylus has a smaller tip to facilitate the selection of smaller icons. However, such a conventional stylus can only operate the resistive touch panel, but cannot operate the above capacitive touch panel. Therefore, once the user has both the electronic device of the resistive touch screen and the electronic device of the capacitive touch screen, the user needs to prepare a corresponding stylus to meet the needs.

The present invention provides a stylus having a plurality of stylus pens.
