Abstract: A liquid crystal display with improved display characteristics is disclosed. An OLED element is used as backlighting device resulting in a very flat liquid crystal display with a backlighting device. At least the front OLED drive electrode is formed such that it is at least partly light-transmissive, so that light from the OLED can be incident on the LCD element. The combination of an LCD element having internal reflectors or internal scattering elements and an OLED backlighting yields a thin overall display element which can be illuminated by sunlight during daytime and which can be illuminated using the OLED backlighting. Both the LCD element and the OLED element or OLED backlighting may represent information. For example, the actual information can be displayed on the LCD element, while the OLED element, primarily functioning as a backlighting device, can additionally represent a logo.

Abstract: A liquid crystal display (LCD) is disclosed including a first cholesteric liquid crystal (LC) layer between a first and second substrate containing a plurality of adjacent alternately arranged pixels of a first and second primary color. A second cholesteric LC layer between the second substrate and a third substrate contains a plurality of adjacent alternately arranged pixels of the first and a third primary color. The first primary color pixels in the first and second LC layer, and the second primary color pixels in the first LC layer and the primary color pixels of the third primary color in the second LC layer, are arranged behind one another. Two first primary color pixels in the first and second LC layer interact with an adjacent second primary color pixel in the first LC layer and an adjacent third primary color pixel in the second LC layer for representing a display pixel.

Abstract: A liquid crystal display device is provided. The liquid crystal display device has a display surface, a sensing device for sensing a light source around the display surface, a control circuit responsive to the sensed light source to adjust a voltage to a controller, which adjusts a transmissivity of the display surface in response to the adjusted voltage.

Abstract: A large surface display apparatus is provided with at least one display field, a control set, a first connection line, and a second connection line. The display field has LCD-modules to display changing information. In one aspect, the first connection line is a light wave conductor and the second connection line is a metallic conductor.

Abstract: A liquid crystal display (LCD) cell is provided having transparent plates that are substantially parallel to each other and contain a liquid crystal display material. A plurality of spacers are interposed between the transparent plates to define a distance between the plates. At least one of the spacers exhibits dimensions and properties different than another of the spacers. The different dimensions and properties operate to control the distance at various temperatures to prevent non-uniform color effects and vacuum void formations.

Abstract: An LCD-pixel-matrix element is disclosed, along with a display screen capable of graphics having a plurality of such LCD-pixel-matrix elements, and a procedure for brightness control of such an LCD-pixel matrix element for such a display screen.
