Projection Systems

Watch Demo 3LCD Projector

3LCD technology enjoys continued growth in projection systems for all types of applications, including data projectors for business, movie theaters and front projectors for home entertainment and projection TVs.

Each projector has a different internal optical system depending on the application and the display device used. Several types of microdevice-type projection systems are available on the market, all of which use one of the following three systems:

  1. 3LCD system

    3LCD is the most widely used projection technology system in the world. 3LCD technology employs three high-temperature polysilicon liquid crystal displays (HTPS LCDs), hence the name 3LCD. This is how 3LCD technology works: white light is divided into red, green, and blue using two dichroic mirrors, special mirrors that transmit light with a certain wavelength. Each color is then passed through a dedicated LCD, before being combined with the other colors in a prism. The image is then ready to be projected onto the screen.

  2. DMD™ and DLP™ systems

    DMD™* (Digital Micromirror Device) is a display technology where hundreds of thousands of carefully positioned micromirrors are arranged on a semiconductor substrate. Each mirror corresponds to a pixel and projects an image by reflecting the light from the source. 1-chip, and 3-chip systems are available. DLP™ (Digital Light Processing) is the name for the optical system that uses DMD™.

  3. LCOS system

    LCOS (Liquid Crystal On Silicon) is a reflective LCD display panel with a high open area ratio. Since the wiring area and switching elements are under the reflection layer, it doesn't require a black matrix area, so images are seamless. 1-chip and 3-chip systems are available.

    • 3-chip LCOS projectors and rear projection TVs achieve high performance by utilizing the high resolution characteristics of this element.
    • 1-chip LCOS systems use a sequential optical drive system with a rotation prism mechanism that divides the light into red, green, and blue and projects the picture.
