HOLOGRAPHIC PANEL, MANUFACTURE METHOD THEREOF AND FULL COLOR COHERENT BACKLIGHT DEVICE

摘要

The present invention discloses a holographic panel, a manufacture method thereof and a full color coherent backlight device. The holographic panel comprises a first substrate, a second substrate and a polymer dispersed liquid crystal between the first substrate and the second substrate, the polymer dispersed liquid crystal is formed corresponding to a holographic fringe of a predetermined wavelength range, and electrode is manufactured on at least one of the first substrate and the second substrate, wherein the polymer dispersed liquid crystal converts an incident light into a collimating coherent light and exits the collimating coherent light when the electrode is not applied with a voltage, and the polymer dispersed liquid crystal is transparentized to the incident light of the predetermined wavelength range when the electrode is applied with a voltage. With the foregoing arrangement, the present invention can provide a large area coherent backlight for a full 3D display.
