COLOUR REFLECTIVE DISPLAY DEVICES

摘要

A colour reflective display device uses two colour absorbing components (40,42), and the quantity of the two colour absorbing components within the pixel aperture can be independently controlled. The first colour absorbing component has a colour (C) at a point lying substantially between the green and blue regions of an (x,y) chromaticity diagram, and the second colour absorbing component has a colour (O) at a point lying substantially between the green and red regions of an (x,y) chromaticity diagram. The invention provides a colour active light shutter layer with only two colour components. One is selected to be near cyan and the other is selected to be near orange, and these together enable a range of colours to be produced which enables good quality colour images to be produced.
