  • Patent number: 6750923
    Abstract: A known display device consists of a sheet-like support which is covered with liquid thermocromic crystals. The crystals are tempered by individual power supply to individual heatable elements, which lie close to the crystals and are placed between the sheet-like support and the crystals. The crystals assume different shades of color dependent on the given temperature so that hereby the color of the crystals will form a certain pattern. In order to improve the possibilities to control the tempering of the individual crystals and also protect them from being effected by the ambient temperature and from mechanical damage, the crystals have an underlying arrangement which is controlled to cool down th crystals and/or keep the sheet-like support of the crystals at a certain temperature. This temperature is lower than the temperature, at which the crystals are colored. Further the crystals are covered by a coating of lacquer over the complete sheet-like support.

  • Publication number: 20040004597
    Abstract: A capacitor structure in a low temperature poly silicon display comprises a buffer layer on a substrate, a poly-Si layer on the buffer layer, a dielectric layer on the poly-Si layer, and an electrically conductive layer on the dielectric layer. At least one of the four layers has an uneven structure. Combining the capacitor structure of the invention with a thin film transistor formed by a LTPS fabrication process forms a pixel structure of a LTPS thin film transistor display. Comparing to the capacitor structure in a conventional display, the capacitor structure of the invention increases the area of the capacitor. Therefore, the storage capacity and the aperture ratio of the LTPS display are increased. The fabrication process is simple. Only one extra process is added to the conventional LTPS display fabrication process and the quality of the display is greatly enhanced.

  • Patent number: 6657611
    Abstract: A system of a computer (PC) and a monitor (DA) enables a user to select a desired white color temperature of display information displayed on a display device (DD) of the monitor (DA). The computer (PC) includes a graphics adapter (GA) for supplying video signals (Ri, Gi, Bi) to monitor (DA). The monitor includes controllable amplifiers for amplifying the video signals (Ri, Gi, Bi) to obtain video drive signals (Ro, Go, Bo) driving the display device (DD). A ratio of values of the video drive signals (Ro, Go, Bo) determines the color displayed. The computer (PC) is programmed to: (i) control the graphics adapter (GA) for generating display information which obtains a graphical representation (L; T) of various colors, and a graphical indication (I; Pl) for graphically indicating white colors in the graphical representation (L; T), and (ii) receive a user command (UC) indicating a selected color (Co) in the graphical representation (L; T).

  • Publication number: 20030142061
    Abstract: One aspect of the invention involves a thermal image generation device comprising a casing forming an interior cavity. One surface of the casing includes a screen with thermochromic material attached to a bottom surface of the screen. The casing houses at least one thermal transfer element movable over regions of the thermochromic material to alter a temperature at the regions from a steady-state, ambient temperature. Such temperature alterations temporarily cause a color variation to the thermochromic material until the regions of the thermochromic material return to the ambient temperature.

  • Patent number: 6583780
    Abstract: The present invention is a method in which microcapsules are placed at desired locations selectively accurately and easily to produce a high accuracy electrophoretic display panel. In the production method of a display panel of the present invention, the microcapsules (43) are uniformly coated onto a substrate (41), on which electrodes (42) is formed by using an optical hardening resin as a binder material (44). Next, the binder material (44) is hardened by selectively irradiating a light beam to the only locations desired for placing the microcapsules (43) by using a photomask (45). The binder material (44) of portions not hardened is removed by washing in water. Thus, the microcapsules can be selectively and accurately placed at the only desired positions.
