Description

Projection e-book

The present invention relates to an electronic book, and more particularly to a projection electronic book, which is capable of generating a function lacking a conventional reflective electronic book by integrating a micro-projection device and a reflective electronic book.

According to the current, reflective displays are mainly small-sized products, and small-sized displays cannot be viewed by many people at the same time. In addition, since the display layer response time of the reflective display is not fast enough - generally more than 200ms - it cannot play animation. When the ambient light is insufficient, the user cannot view the display content of the reflective display. Furthermore, even if the ambient light is sufficient, it is extremely difficult for a visually impaired person to view the display content of a small-sized display, which may require a magnifying glass to assist.

In order to solve the aforementioned disadvantages of the reflective display, it is helpful to increase the size of the reflective display, but it still cannot solve the problem of reading when the ambient light is insufficient and the animation cannot be played because the reaction time of the display layer is not fast enough.

In view of this, the present invention proposes a novel display architecture, which has a plurality of functions, in addition to displaying a static picture and a dynamic picture when the ambient light is insufficient, and even browsing the webpage on the Internet for the user. Provide an instant information query pipeline.

Another object of the present invention is to disclose a projection e-book that can select a representation of a web address on an e-book to display a dynamic web page or a static web page by a micro-projection device and/or by electronic The book displays a static web page.

In order to achieve the above object, a projection e-book is proposed, which has an electronic paper device that receives a picture information according to an electronic paper input and displays it on an electronic paper panel; a control unit having a video input port, a first display output port, and a second display output port for receiving an image information and/or a sound message via the video input port, and outputting the second display output or the second display output埠 outputting the image information, wherein the first display output is coupled to the electronic paper input port; a video storage unit coupled to the audio input port to output the image information and/or the sound information; and a micro The projector is coupled to the second display output port to project a picture according to the image information.

The invention has the following functions:

1. The e-book of the present invention can be read by many people at the same time, for example, for conference presentation, photo sharing, reading sharing, and the like.

2. The electronic book of the present invention uses projection to make the display area larger.

3. The electronic book of the present invention can play a movie by projection.

4. The electronic book of the present invention can display the content of the electronic book by projection in the case of insufficient ambient light.
