Abstract

A tablet computer with a separate miniature laser projection device. The tablet replaces a traditional LCD screen with a separate miniature laser projection unit. The separated miniature laser projection device includes a laser light source module, a control circuit, a miniature scanning device, a connecting rod, an optical fiber and an auxiliary optical system. The laser light source module and the control circuit are separated from the micro scanning device. The laser light source module and the control circuit are integrated inside the tablet computer; the micro-scanning device is located outside the tablet computer and connected with the tablet computer through a rotatable mechanical link. The red, green and blue laser light generated by the laser light source module is transmitted to the micro-scanning device through an optical fiber and projected into a two-dimensional image. The invention has the advantages of small size, light weight, wide color gamut, high contrast, large visual range and the like.

Description

technical field [0001] This patent relates to a tablet computer with a separate micro-laser projection device. The tablet uses a separate micro-laser projection device instead of a traditional LCD screen. The laser light source module and control circuit of the separated micro-laser projection device are separated from the micro-scanning device. The red, green and blue laser light generated by the laser light source module is transmitted to the micro-scanning device through an optical fiber and projected to project a two-dimensional image on the surface of the tablet computer or an external screen. Background technique [0002] Tablet PC usually refers to a small portable computer that integrates a liquid crystal display with a touch module and a tablet host without a built-in keyboard, and has recently been widely used for personal entertainment and information processing. For example, the ipad of the U.S. Apple Inc., as a typical tablet computer, adopts a 9.7-inch LCD sc...
