Patent ID: 8547406

Claim:
Display element with at least one color-generating cell of a first type ( 1 ), which has an emissive light source, and with at least one color-generating cell of a second type ( 2 ), which has a reflective and/or transmissive and/or transflective light source comprising a stack of first reservoirs lying one on top of one another, and a respective number of second reservoirs, whereby each of said first reservoirs is adapted to be selectively filled with a clear fluid, or with a magenta-colored, cyan-colored or yellow-colored fluid, wherein each individual fluid can be moved between one of said first and one of said second reservoirs, and whereby only the stack of first reservoirs is in the optical path of the light inside the cell of the second type ( 2 ), whereby the cells ( 1 , 2 ) are located next to one another and each cell of the second type ( 2 ) is driven as a function of the difference between a desired point in the color space and an actual point in the color space which corresponds to a modified color impression on account of the ambient light of the display element, so that it makes visible at least one of the chromatic colors red, green, blue, magenta, cyan and yellow and the achromatic colors white and black, to compensate at least partly for the absence of the color impression produced by the at least one color-generating cell of the first type ( 1 ).
