LCD technology is used by many manufacturer’s such as Epson, Hitachi ,and NEC.
LCD (liquid crystal display) projectors contain three separate LCD glass panels, one for red, green, and blue components of the image signal being transferred to the projector. As the light passes through the LCD panels, individual pixels can be opened to allow light to pass or closed to block the light. This activity modulates the light and produces the image that is projected onto the screen.
- LCD is generally more 'light efficient' than DLP (ie. the same wattage lamp in both an LCD and DLP would produce a brighter image through the LCD).
- With 3LCD projectors, you get beautiful colour in clear, defined images - even in a bright room, and you get more than double the brightness on colour luminance, compared to non-3LCD projectors. What’s more, 3LCD projectors can project bright, vivid images with a low output lamp.
- Hence, with a data signal, if you put a 1000 lumen LCD next to a 1200 lumen DLP and showed a colour image people would probably prefer the LCD.
- LCD tends to produce a sharper image (ie. more precisely focused). This can actually be a bit of a disadvantage for video, where it makes the pixellation more obvious.
