Abstract: An electrical element, such as a thin-film transistor, is defined on a flexible substrate, in that the substrate is attached to a carrier by an adhesive layer, and is delaminated after definition of the transistor. This is for instance due to illumination by UV-radiation. An opaque coating is provided to protect any semiconductor material. A heat treatment is preferably given before application of the layers of the transistor to reduce stress in the adhesive layer.

Abstract: A display apparatus includes a plurality of electrofluidic chromatophore (EFC) pixel cells. Each pixel cell includes a fluid holder for holding a polar fluid and a non-polar fluid having differing display properties, the fluid holder including a reservoir having an orifice with a small visible area projected in the direction of a viewer onto the polar fluid, and a channel with a geometry having a large visible area projected in the direction of a viewer onto the polar fluid. The channel is connected to the reservoir via said orifice so as to enable free movement of the polar fluid and non-polar fluid between the channel and the reservoir. The reservoir is formed in a laminated resin structure of homogenous resin film layers, including an orifice film layer and a reservoir film layer.

Abstract: The invention relates to a display structure comprising an electrode layer (3) superposed on a sub-layer (5) wherein a surface of the sub-layer facing the electrode layer is roughened. In particular, the display structure may relate to a TFT stack comprising a layer of an electrode metal corresponding to a pixel electrode (3). The pixel pad together with the data line (1) is used for charging of the pixel pad. The gate electrode (4) used is separated from the source and drain electrode (1, 3) by a dielectric layer (6). The structural layers of the TFT may be deposited on a suitable flexible substrate (7). In order to prevent defects in the light modulating layer (9) from being visible, a surface of the sub-layer (5) underlying the electrode layer (3) is roughened. It is desirable to provide such improvement to, among others, electrophoretic-type displays and liquid crystal-type displays.

Abstract: A method is described for manufacturing a display. The method includes providing a display layer for displaying an image having at least a luminosity component, providing a color filter layer comprising a color filter for filtering the image according to a predetermined pattern, and removably attaching the color filter layer to the display layer. Dependent on the outcome of a test on the product provided with the removably attached color filter layer it may be decided to remove the color filter layer.
