摘要

The present invention is about a smartphone system with two touch screen displays. Fashion items such as handbags, backpacks, toolboxes and jackets etc., which are carried or worn in daily life by most women, students and professionals, usually have a flat surface area much bigger than the screen of a typical smartphone. Such flat surface on daily used item is ideal for installing a touch screen device for alternatively displaying heavy content, which is difficult to be seen clearly on a small screen of a typical smartphone. The display device works as a master in slaving the smartphone for most of its functions which need bigger display screen. Such display devices can be much cheaply built as compared to conventional tablets and can be attached permanently or temporarily to handbags or backpacks and the likes.
