Abstract
An exemplary display device based on layer displacement having a perforated white substrate positioned close to a transparent substrate. Layer (fluid) displacement such as oil movement results in the (colored) oil film being pumped in a controlled manner above the white substrate. Fluids of three subtractive colors can be independently pumped to separate spaces. Based on the color strength of the used fluids good color rendition can be obtained for a flow channel thickness of less than 25 microns and therefore a total pixel thickness including the sub pixel reservoirs of less than 200 microns.
