The micro projector, since the second half of 2008 into mass production, liquid crystal on silicon (LCoS) and TI (Texas Instruments) independently developed the digital light processing (Digital Light Process; DLP),there are two technical, and called the mainstream for micro projection technology. At present, two kinds of micro projection technology using LED as the light source, in LED mass production
as the LED production of the high ability of mass production manufacturers more and more, the cost is also continued to decline. Among them, the LCoS micro projection technology can be used for white light LED with color filter, effectively reduce the micro projector costs, and enhance the penetration rate.

In 2010, with the consumer electronics market is gradually recovering, terminal manufacturers and consumers of micro projector technology requirements will be more strict. Therefore micro projector quality development will have three major trends, including brightness upgrade, the resolution improvement, and improved color performance.

In order to improve the luminance, LED vendors are increased the LED luminous efficiency year by year white LED with a color filter, although the advantage of reducing costs, but inevitably affect the color performance, so LCoS pico projectors terminal manufacturers have shift to RGB Full color LED pixel light source. As for the resolution, although decided by the panel side in theoretically , but if the brightness of less than a certain standard, then high resolution panel, is immune to the appropriate display.In addition to LED, the laser also has bigger opportunity for mini projector light source potential. At present, although there have been a variety of new micro projection technology with laser light source, but only American Microvision alone developed the two-dimensional scanning MEMS micro-projection technology has been introduced into mass production in early 2010.
Although the laser light collimation good because without merit manual focus, but will thus cause the laser spot (Speckle) phenomena affect the quality, though not not be solved, but still big trouble.
In addition, the current due to the green laser into volume production time soon, and only American Corning (Corning) can be mass production, the price is expensive,  so with laser in the mini projector light source to achieve popularity may have more than 2 years.

The Diffused LED Pixel Module can be used to draw a target point with cast light, the distribution of light have isotropic properties, spotlight and web three options.The function and target of The Diffused LED Pixel Module light source is same whit light source of target.  just not the target point, the user can change the direction of the light. Similarly, the free light also has above three kinds of light control light distribution properties. Line source is also divided into goal line source (Target Linear) and free line source (Free Linear)  two types.
Target line can be used to cast light source to a target object, which has a diffuse light distribution properties (Diffuse) and mesh (Web) two kinds. Freedom line source function and target line light sources, but no target object, the user can change the direction of the light.

The same free linear LED point light source also has above two kinds of spectrophotometric control properties of light distribution. Wherein the diffuse distribution of the light will be the greatest at an angle to the surface of the projection light intensity, as light intensity decreasing angle of tilt， Web distribution type allows users to customize the intensity of the light emitted. Led light source Typical applications

1, LED point light source combined into a sphere light display: LED point light source to made the sphere of light screen
2, the combination of LED point light source into a super large LED curtain screen:
