PHOTOLUMINESCENCE COLOR DISPLAY

摘要

A photoluminescence color display comprises a display panel that displays red, green and blue sub-pixel areas, an excitation source operable to generate excitation radiation for operating the display, and a combined layer of photoluminescence materials and filter pigments. The combined layer comprises at least one photoluminescence material, such as a phosphor material or quantum dots, that is operable to emit light corresponding to red, green and blue sub-pixel areas of the display in response to said excitation radiation.

主权项

1. A photoluminescence color display comprising:
a display panel comprising a plurality of red, green and blue sub-pixel areas; and an excitation source operable to generate blue light for operating the display; wherein said red sub-pixel areas comprise a mixture of a first photoluminescence material that is operable to emit red light in response to said blue excitation light and a first color filter pigment that allows the passage of blue light and red light whilst substantially preventing the passage of green light; said green sub-pixel areas comprise a mixture of a second photoluminescence material that is operable to emit green light in response to said excitation radiation and a second color filter pigment that allows the passage of blue light and green light whilst preventing the passage of red light; and said blue sub-pixel areas comprise a third color filter pigment that allows the passage of blue light whilst preventing the passage of red light and green light.
