Definition - What does LCD Projector mean?
An LCD projector is a type of projector based on liquid crystal displays which can display images, data or video. An LCD projector works on transmissive technology. LCD projectors are more popular than many alternatives due to the fact that they are cheaper to produce and have excellent color reproduction. They are commonly used in business meetings, presentations and seminars.
Techopedia explains LCD Projector
The light source for an LCD projector is a standard lamp. An LCD projector allows the source light to pass through the three colored liquid crystal display light panels. The panels in turn allow some colors to pass through and block some colors to form the images on the screen.
There are several advantages of using an LCD projector. Higher lumen output can be delivered by an LCD projector at a lower cost compared to a digital light processing (DLP) projector. It can also provide greater brightness with lower energy consumption. Unlike DLP projectors, LCD projectors do not suffer from rainbow effects and dithering. Another salient feature of LCD projectors is their image sharpness and providing greater zoom magnification.
However, there are certain disadvantages associated with LCD projectors. They can be comparatively bulkier than other projectors, with lesser portability. The LCD panels have a limited lifetime, they do not have high contrast, and may suffer from black and dead pixels. Maintenance can be higher in the case of LCD projectors when compared with other projectors. If an LCD projector is used frequently over a long period of time, image degradation is possible, and they also heat up more quickly than DLP projectors.
