Problems solved by technology

[0005] Since the above-mentioned projection system must adopt a spectroscopic system, a light-collecting system, and a projection system, the number of components is large and the structure is complex, and it is not easy to integrate it into various portable electronic devices, such as mobile phones, laptops, etc.
In addition, the light source used in the above-mentioned projection system consumes a lot of power, and generally needs to be equipped with a heat dissipation system to dissipate the heat generated by the light source during the light emitting process, which also complicates the structure of the portable electronic device

Embodiment Construction

[0019] Preferred embodiments of the present invention are described below in conjunction with accompanying drawing:

[0020] see figure 2 , a portable electronic device 100, such as a mobile phone, a personal digital assistant, a game console, a notebook computer, etc., can directly project an image frame to a display screen 340, wherein the display screen 340 is marked as an O-XY coordinate plane. The portable electronic device 100 includes an input system 102 , a display system 104 , sound systems 103 , 105 and a projection system 108 . The input system 102 may be a keyboard for entering information and commands. The display system 104 may be an LCD display screen for displaying text information or function selection menus. The sound systems 103 and 105 can be microphones and speakers respectively, and are used for inputting and outputting voice signals. The projection system 108 is installed at one end of the electronic device 100 for projecting images. One side of the...

Abstract

The present invention relates to a projection system, which comprises a light source unit, a light collecting unit and a dynamic scanning unit. The light source unit can emit at least two monochromatic light beams; the light collecting units transforms the monochromatic light beam into a single light beam; the dynamic scanning unit rotates with certain frequency and is used for reflecting the single light beam to a display screen so as to achieve the simplification of the structure. In addition, the present invention also provides a portable electronic device which adopts the projection system.

Description

technical field [0001] The present invention relates to a projection system and a portable electronic device using the projection system. Background technique [0002] Projection systems, such as LCD projectors and DLP projectors, are mainly used for document presentation, large-size movie screen display, etc., to facilitate office work and personal entertainment. [0003] Existing projection systems usually use a pixelated matrix method to display images, that is, to divide the image into several tiny pixel units, such as VGA (Video Graphics Array 640*480) and SVGA (Super Video Graphics Array 800*600) specifications, etc. . By controlling micro-devices such as liquid crystal molecules or DMD, the brightness, chromaticity, etc. of each pixel unit are changed to form a visually perceivable picture. [0004] like figure 1 As shown, a typical projection system 400 includes a light source 410 , a light splitting system 420 , a light modulation system 430 , a light collection ...
