What does LCD stand for?
LCD stands for Liquid Crystal Display. It is a display component most often found on notebook computers. LCD is a technology that uses rod-shaped molecules (liquid crystals) that flow like liquid and bend light. Unenergized the crystals direct light through two polarizing filters, allowing a natural background color to show. When energized, they redirect the light to be absorbed in one of the polarizes to show. The more the molecules are twisted the better the contrast and viewing angle.

What are VGA, SVGA, XGA and SXGA?
These are computer resolution standards defined by Video Electronic Standard Association (VESA). It is an industry standard for resolutions of personal computers. VGA is 640 x 480, SVGA is 800 x 600, XGA is 1024 x 768 and SXGA is 1280 x 1024.

What is DLP? and DMD?
DLP? stands for Digital Light Processing and DMD? stands for Digital Micro-mirror Device. This system is based on thousands of tiny mirrors move to reflect the light and create the image on a projection screen. In electromagnetic, we call it DMD? (Digital Micro-mirror Device) and in optics, we call it DLP? (Digital Light Processing). Our EzPro700 uses this DLP? technology, which gives it true colors, a compact size, and high performance. For more information on DLP? technology, please refer to Texas Instruments web site


What is single panel LCD projector?
This is one kind of LCD technology which projects light through a single amorphous liquid crystal panel containing red, green and blue pixels. It usually makes the projector more compact and lighter. Our EzPro 550, and 585 uses this single TFT LCD panel which makes our projectors ultra portable and more affordable.

What is three-panel LCD projector?
This is one kind of LCD technology which projects light through three polysilicon LCD panels, one each of red, green and blue, to achieve the final projected image. These panels are the size of a quarter ( There are three kinds in the market including 0.9", 1.3" and 1.8"). Since each panel displays only its primary color, better color saturation and a larger color palette can be achieved. Also, the three-panel design provides a much greater contrast ratio.
