Embodiment Construction

[0042] Efficiency of projectors degrades due to losses including: spectral loss (if a broadband light source is used), loss due to poor internal efficiency of the light source, loss due to poor external efficiency of the light source (e.g. using LEDs) , light combining loss (collimation loss), integration loss (if combining several beams), color separation loss (loss in the dichroic mirror used to split light into red, green and blue components), polarization loss (if using LC microdisplays), reflection or transmission losses in the microdisplay itself, e.g. due to poor fill factor (gaps between pixels), color combining losses (e.g. when using X-cubes or dichroic mirror), and the loss of the projection lens (reflection loss on the lens surface).

[0043] It is very important to minimize light loss in every respect. It is also desirable to maximize the internal and external quantum efficiency of the light source. Light should be directed only to the active area of ​​the micro...

Abstract

The present solution relates to a 2D / 3D data projector, which comprises: A data projector, the data projector comprising: at least one micro display having an image to be projected, at least one source unit comprising at least one light source chip, said source unit further comprising at least one beam forming component, said at least one beam forming component comprising a plurality of surfaces disposed in a three dimensional configuration, at least one of said plurality of surfaces comprising micro-structure optics, and a focusing optical unit for projecting the image of the micro display on a target.

Description

technical field [0001] The invention relates to devices for displaying images by projection. Background technique [0002] Current mobility trends are driving user consumer demand towards smaller and smaller portable devices such as mobile phones, portable digital assistants, music and video players, laptops, head-mounted displays, and more. As sizes get smaller and more functional, there is a fundamental problem of displaying a large enough visible image on a very small device. Since the size of the fixed screen cannot be increased without increasing the size of the device itself, the only reasonable way to conveniently provide a visible image from a small device is to project it using a data projector. However, current data projectors are large in size and inefficient in practical applications. [0003] Commercially available data projectors use high intensity broadband light sources such as incandescent bulbs or arc lamps. These light sources are inherently inefficient...
