LCD vs DLP Projector

Projector on the market currently use two types of technologies: LCD (Liquid Crystal Display) and DLP (Digital Light Processing). Both have advantages.

The LCD most widely available. This technology allows the light generated more efficient. That is, with the same electrical power, an LCD projector beam brighter than any DLP.

Color saturation even better results, as well as sharpness. Only this type of projector has a weakness, which is called “chicken wire effect”. This is the visible image effects fragmented, due to pixels that are not meeting. In contrast to the DLP that looks fine, because pixelnya close.

General form of an LCD projector is bigger. In addition, the risk of dead pixels, which would interfere with the display permanently.
DLP projectors have a contrast images better. In addition, generally more portable and lighter.

The cause of fat-bodied LCD projectors are too many components in it. Consists insigh and three LCD glass panels, each of which serves to channel the red light, green, and blue.

When the light through the LCD panel, the system will determine the activity of each pixel: open or closed. This activity will modulate the reflected light and produce images.

The lastest LCD projectors have been equipped with the special optics to boost the quality of projections, such as micro mirror that can reduce the effects of the projected box. Contrast ratio 800:1 LCD projectors generally, or equivalent to 3000:1 contrast ratio on DLP technology.

DLP technology systems different from the LCD. This digital projection technology was developed by IT vendors named Texas Instruments (www.ti.com). Now, the system is divided into two types: one chip and three chips. That many in the market is the first, but the second type of projection quality much better.

DLP systems use a semiconductor called the Digital Mirror Device (DMD), which consists and thousands of micro mirrors in it. These mirrors will attract resources into the system image. In the device, the object is re-created digitally, and then projected onto a screen.
