Abstract:
The invention relates to a color display device for display a color image and a method of operating such display. The color display device is provided with a plurality of picture elements, two selectable light sources having different predetermined radiance spectra, color selection means which in combination with the selectable light sources is able to produce respective first and second primary colors on the display panel and control means arranged to select alternately one of the selectable light sources and to provide a portion of the picture elements with image information corresponding to the respective primary colors obtainable with the selected light source. The primary colors of the display device can be selected in a time sequential and space sequential way which enable a reduction of a color break-up.
Abstract:
The present invention discloses an electronic device (100) comprising a substrate (10) carrying an electrode structure (12); an electro-optical stack (90) at least partially covering the electrode structure (12), the electro-optical stack comprising a stratified polymer layer (44), a further substrate (20) and an electro-optical material (32) sandwiched between the polymer layer (44) and the further substrate (20); and an adhesive layer (60) between the substrate (10) and the electro-optical stack, as well as a method for producing such an electronic device (100), in which the electro-optical stack (90) and the substrate (10) are prepared in separate processes and combined by an adhesive layer (60). This improves the yield of such an electronic device (100), because a production error in one of the components no longer leads to the loss of the whole electronic device (100). Also, sensitive components on the substrate (10) such as polymer based TFTs, are protected from exposure to the processing steps of the electro-optical stack (90).
Abstract:
The electronic device (1) of the present invention has a carrier (10) with a plurality of discrete electro-optical elements (110, 130, 150) mounted on the surface of the carrier (10). The electro-optical elements (110, 130, 150), which cover respective parts of the electrode structure (12) on the surface of the carrier (10), each have a polymer layer (114, 134, 154), which encloses an electro-optical material (102, 122, 142) between the polymer layer (114, 134, 154) and the surface of the carrier (10). The discrete electro-optical elements (110, 130, 150) have been formed by the individual deposition of discrete droplets of a liquid comprising the electro-optical material and a polymer precursor followed by exposure of the droplets to a stimulus triggering the polymerization of the polymer precursor.
Abstract:
A color filter includes first, second and third regions for providing polarized light of a first, for example red, a second for example green and a third for example blue color respectively. To provide polarized light, a region comprises an isotropic colorant for selectively transmitting the first, the second or the third color, a uniaxially ordered base material and a dichroic colorant aligned by the uniaxially ordered base material for absorbing light selectively transmitted by the isotropic colorant. In a liquid crystal display device comprising such a color filter a polarizer can be dispensed with resulting in a simpler, more cost effective and robust display device.
