Projectors

Digital Light Processing (DLP) is a set of chipsets based on optical micro-electromechanical technology that uses a digital micromirror device.
DLP was originally developedin 1987 by Larry Hornbeck if Texas Instruments. DLP is used in a variety of display applications from traditonal static displays to interactive displays and also non-traditional embedded applications including medical, security and industrial uses.

DLP technology is used in DLP front projectors (standalone projection units for classrooms, business primararily and home), DLP rear porjection television sets, and digital signs. It is also used in over 90% of digital cinema projection, and in additive manufacturing as a light source in some pronters to cure resins into solid 3D objects.

Hotack is the market leader and technology-driven comapny for the DLP projector. We rank one of the top three manfacturers in global projector market.

An LCD projector is a type of projector based on ligquid crystal displays (LCD) which can display images, data or video.
The light source of an LCD projector is a standard lamp. It allows the source light to pass hrough the three colored liquid crystal light panels. The panels in turn allow some colors to pass theough and block some colors to form the images on the screen.

Adantages
1. Higher lumen output can be delivered by an LCD projector at a lower cost compared to a DLP projector.
2. It can also provide greater brightness with lower energy consumption.
3. Unlike DLP projectors, LCD projectors do not suffer from rainbow effects and dithering.
4. Another salient feature of LCD projectors is their image sharpness and providing greater zoom magnification.
