Electronic display system to show large size visual content on a small size display device

摘要

A portable display system for an electronic device is invented, which consists of a portable display and a pair of eye glasses. The size of the display is small for easy carrying, for example, the display can fit in to a hand. The resolution of the display is changeable, for example, it can be lower than one hundred by one hundred for normal cell phone usage. It can be as high as thousands by thousands to show HDTV, movie, and web browsing. When the display is in its low resolution mode, naked eyes can see the display content without problem. When the display is in its high resolution mode, the pair of glasses, which enlarges the display content a few times, is needed. There may be, depending of application, multiple resolution modes between the lowest and the highest.;The display system may allow interactive input from users. For example, a user is surfing the Internet using a cell phone, via the pair of glasses. When the user wants to follow a link, the user's finger taps the link on the display. If the area touched by the finger tip contains exactly one link, the link is followed and a new web page is shown. However, since the display content is magnified by the glasses, the area touched by the finger tip may contain other links besides the link. At this time, the display magnifies the area to allow the finger tip to pin point to a unique link. What the user sees is that the area touched by the finger tip is enlarged more than other parts of the display not touched by the finger tip. If the user does not tap again for some time, for example, a few seconds, the enlargement for the area disappears. On the other hand, if the user taps again and the area touched by the finger tip contains multiple links still, the area is magnified further. Other input media apart from web links, include but not limits to, software button, menu, list, keyboard, etc.;The invention is not about a resolution changeable display, nor about a pair of magnifying glasses. The invention is about a set of compatible displays and a pair of glasses, which work together to enable people use or enjoy visual content usually based on large size display.
