Embodiment Construction

[0022] Fig. 1 shows a schematic cross section of a part of a display device 1, eg a pixel, illustrating the principle on which the display device according to the invention is based. Between the two transparent substrates or support plates 3, 4, a first fluid 5 and a second fluid 6 which are immiscible with each other are provided. For example the first fluid 5 is an alkane like hexadecane or in this case a (silicone) oil. The second fluid 6 is conductive or polar, such as water or a saline solution (eg a solution of KCl in a mixture of water and ethanol). A reflective display pixel is realized by means of a diffuse mirror 10 located below the oil, in this example below the transparent substrate 7 .

[0023] In the first state, when no external voltage is applied ( Figure 1a ), the fluids 5, 6 adjoin the first and second transparent support plates 3, 4, eg made of glass or plastic. On the first support plate 3, a transparent electrode 7 is provided, for example indium oxid...

Abstract

A display device or optical switch, based on layer break up or layer displacement having at least two different states, in which one of the fluids (5) e. g. oil in a first state adjoins at least a first support plate (3) and in the second state the other fluid (6) at least partly adjoins the first support plate, in which sub-picture elements are separated by areas (13) having a hydrophilic surface.

Description

technical field [0001] The invention relates to a display device comprising pixels, each pixel having at least one first fluid and a second fluid immiscible with each other in a space between a first support plate and a second support plate, said first fluid being immiscible with each other. The second fluid is conductive or polar. Background technique [0002] Display devices like TFT-LCDs are used in laptop computers and organizers and also find wider and wider applications in GSM phones. As an alternative to LCDs, eg (polymer) LED displays are also used. [0003] In addition to these hitherto well-established display effects, other display technologies are also being developed, such as electrophoretic displays for paper white applications. [0004] More generally, the present invention relates to an optical switch comprising mutually immiscible at least one first fluid and a second fluid in a space between a first support plate and a second support plate, said first flu...
