REFLECTIVE COLOR DISPLAY WITH LUMINESCENCE AND BACKLIGHTING

摘要

A reflective color display has at least a color pixel disposed to receive ambient light for front lighting and has a light source optically coupled to the color pixel to provide back light for backlighting. The color pixel has a first sub-pixel and a second sub-pixel. The first sub-pixel has a first luminescent layer with a luminescent material for converting a portion of the ambient light spectrum into light of a first color. An unpatterned mirror is disposed under the luminescent layer of the first sub-pixel and extends through the first and second sub-pixels. The unpatterned mirror reflects at least light of the first color while transmitting the back light to the first luminescent layer for conversion by the first luminescent material into light of the first color.

1. A reflective color display comprising:
at least one color pixel disposed to receive ambient light for front lighting; anda light source optically coupled to the color pixel to provide back light for backlighting the color pixel, the color pixel having: a plurality of sub-pixels including a first sub-pixel and a second sub-pixel, the first sub-pixel having a first luminescent layer containing a first luminescent material for converting a portion of an ambient light spectrum into light of a first color, and an unpatterned mirror disposed under the first luminescent layer of the first sub-pixel and extending through the first and second sub-pixels, the unpatterned mirror reflecting at least light of the first color while transmitting the back light to the first luminescent layer for conversion by the first luminescent material into light of the first color.
