3LCD Technologies

Since the launch of the VPJ-700, its first 3LCD projector, in 1989, all subsequent projectors produced by Epson have been 3LCD projectors. Epson made this decision based on its conviction that the 3LCD method offered the brightness and vividness that would be ideal for projectors.

Projectors that employ 3LCD technology create visuals by using three LCDs (HTPS* liquid crystal panels), and include a sophisticated combination of Epson's original microdevice and optical component technologies. The colors that form color visuals are created by splitting light into the three colors of red, green, and blue, each having different wavelengths (these colors are referred to as the "three primary colors of light"). A 3LCD projector works by first splitting white light from a lamp into the three primary colors by using special dichroic mirrors. Each of the primary color beams of light is passed through its own individual liquid crystal panel, giving form and movement to the image. The three separate beams of light are recombined in a prism, creating color visuals made up of every possible color and expressing every type of movement, resulting in the reproduction of truly natural and beautiful colors.

* High-temperature polysilicon (HTPS) refers to a compact, high-resolution liquid crystal panel.

3LCD technology features the following advantages

  • 1. Bright color images
    Because light is used with such high efficiency, colors are produced that are beautifully vivid, even when viewed in a bright room.

  • 2. Natural images
    Producing a very wide range of colors and detailed gradation makes it possible to faithfully project natural images that are true to their original colors.
  • 3. Images that are gentle on the eyes
    As colors are reproduced using three liquid crystal panels, the images are free from the problem of color breakup* or bothersome flicker.

* Color breakup is a phenomenon in which a rainbow-like effect is generated due to the relationship between the movement of the images on screen and the movement of the eyes of the viewer.
