3LCD technology refers to a video projection system that uses three LCD panels to produce an image. 3LCD is certainly the most admired micro-display projection technology globally, delivering high quality images for the most discerning business and consumer audiences. 3LCD technology uses active matrix that produces sharper and clearer images.
Highly reliable and sophisticated 3LCD technology is designed to project bright, clear and brilliant images even in high ambient light situations. 3LCD projector color reproduction range is extensive, and primary colors are authentically reproduced. Better gray scale in dark areas facilitates additional natural gradation. 3LCD projectors display constant images that do not suffer from color disintegration and facilitate high definition performance.
3LCD prominently figures among several present-day flat panel display technologies including; Plasma Display Panel (PDP), Organic Light Emitting Diode (OELD), Thin-film Electroluminescent (TFEL) and Field Emission Display (FED). Using 3LCD micro displays provides manufacturers with a projection solution for enhancing resolution while maintaining compactness.
With the advent of 3LCD in 1995 it has been adopted by several leading TV manufacturers including, Fujitsu, Hitachi, Panasonic, Sanyo and Sony for its compactness and high resolution image quality.
Liquid Crystal Display
LCD refers to a transmissive technology that needs a backlight source usually an ultra-high-pressure mercury lamp. The light generated by the backlight is controlled by liquid crystals. The liquid crystal solution is squeezed in between two sheets of a polarizing material (either glass or plastic). By altering the electric current passing through the solution transform the crystals opaqueness and enables the display of desired image on the screen.
HTPS (high-temperature polysilicon) Projection System
HTPS is an active matrix transmissive LCD that offers several advantages over LCDs using other systems such as, higher resolution and higher contrast and can even embed drivers. The light passes through an ultrahigh pressure mercury lamp which is split into red, green and blue using a dichromic mirror, which passes light with a certain wavelength while reflecting a particular wavelength which creates the required image. A prism amalgamates all three images back into a single image. Optical lenses are used to extend the images from the prism to an appropriate display size.
Continued Development
3LCD projection is swiftly catching the nerves of the consumers with their developing technology. The latest example of constant innovation is the introduction of HTPS panels using an inorganic alignment layer for better contrast levels and deeper blacks.
