Photo-luminescence color liquid crystal display
First Claim
1. A photo-luminescence liquid crystal display comprising:
- a display panel and a radiation source for generating excitation radiation for operating the display;
wherein the display panel comprises transparent front and back plates;
a liquid crystal disposed between the front and back plates;
a matrix of electrodes defining red, green and blue pixel areas of the display and operable to selectively induce an electric field across the liquid crystal in the pixel areas for controlling transmission of light through the pixels areas;
a red phosphor material which emits red light in response to excitation radiation, the red phosphor material being provided on the back plate corresponding to red pixel areas and a green phosphor material which emits green light in response to excitation radiation, the green phosphor material being provided on the back plate corresponding to green pixel areas.

Abstract
A photo-luminescence liquid crystal (LCD) display comprises: a display panel and a radiation source for generating excitation radiation for operating the display. The display panel comprises transparent front and back plates; a liquid crystal disposed between the front and back plates; a matrix of electrodes (array of thin film transistors TFTs) defining red, green and blue pixel areas of the display and operable to selectively induce an electric field across the liquid crystal in the pixel areas for controlling transmission of light through the pixels areas. A red phosphor material which emits red (R) light in response to excitation radiation is provided on the back plate corresponding to red pixel areas and a green phosphor material which emits green light in response to excitation radiation is provided on the back plate corresponding to green pixel areas.
