PORTABLE ELECTRONIC DEVICE HAVING AN ELECTRO WETTING DISPLAY ILLUMINATED BY QUANTUM DOTS

摘要

A portable electronic device (510) includes an electrowetting display (200, 202, 204, 206, 300, 512) having a plurality of transparent layers defining a cavity (219). A combination of a first fluid (218, 236) and a second fluid (210, 234, 244, 254) are positioned in the cavity. First circuitry (224) is coupled to a voltage source (222) for selectively repositioning the second fluid (210, 234, 244, 254) in relation to the first fluid (218, 236). A plurality of quantum dots (208, 360) is positioned within the second fluid (210, 234, 244, 254), and a light source (209, 309) is disposed contiguous to the plurality of layers. Second circuitry (228) is coupled to a voltage source (226) for selectively causing the light source (209, 309) to emit photons to strike the plurality of quantum dots (208 360). Similar stacks of layers (204, 206) may be added to provide a color display.
