Display device based on frustrated total internal reflection
First Claim
1. A display device comprising a substantially transparent substrate having a substantially flat surface and a substantially prismatic surface facing said flat surface, said display device comprising a reservoir at the location of a pixel, which reservoir contains at least two substantially immiscible fluids having a different refractive index or a different absorption coefficient, and a difference of electric conductivity, said display device also comprising drive means for displacing the fluids with respect to each other.

Abstract
Pixels of a display device include a reservoir containing two immiscible fluids. Switching of a pixel state is based on redistribution of the fluids within the reservoir due to electrostatic forced applied onto electrodes, and a potential applied to one of the fluids which is electrically conducting.

14. A display device comprising:
-
a substantially transparent substrate having a substantially flat first surface and a substantially prismatic second surface opposite said first surface; a plurality of row electrodes extending in parallel across the substrate in a first direction; a plurality of column electrodes extending in parallel across the substrate in a second direction; and a plurality of pixels arranged in a matrix at areas where the row electrodes cross the column electrodes, wherein each pixel comprises; a reservoir containing two substantially immiscible fluids having a different refractive index or a different absorption coefficient with respect to each other, and a difference of electric conductivity with respect to each other, and means for selectively displacing the two fluids with respect to each other, wherein in a first arrangement of the fluids light received by the pixel is substantially reflected by the pixel, and in a second arrangement of the fluids light received by the pixel is substantially absorbed by the pixel. - View Dependent Claims (15, 16, 17, 18, 19, 20)
