REFLECTIVE COLOUR DISPLAY DEVICE

摘要

A reflective colour display device comprises a plurality of capillary sub-pixels arranged side by side. Each capillary sub-pixel has a first end and a second end, and a scattering medium disposed between said ends. Each capillary sub-pixel contains a transparent coloured medium which can be reversibly changed to a medium with a different light absorption property in an optical modulation region between the first end and the scattering medium. The optical modulation region of each capillary sub-pixel has a height to width aspect ratio of at least about 3. Light incident on the scattering medium through a first sub-pixel will be scattered into at least one neighbouring sub-pixel having a coloured medium of different colour to coloured medium in the first sub-pixel.
