Abstract
A display apparatus having a structure in which planar multicolor light sources (201, 202, 203, and 204), such as ELs, are used as multicolor light sources, and a planar optical modulation panel (210) is combined therewith. In contrast with a construction in which a multicolor cold-cathode tube and a light valve are driven by time division, the outer shape of the display apparatus can be reduced, power consumption is reduced, and excellent color display can be performed.

6831627 - Driving method for liquid crystal display - Owned by NEC LCD Technologies, Ltd. (JP)

A liquid crystal display includes an electro-luminescence portion which has electro-luminescence elements and a liquid crystal portion which has liquid crystal layer, scanning electrodes and signal electrodes and controls the transmittance of light emitted by the electro-luminescence elements. First, scanning pulses are applied in sequence to the scanning electrodes. Next, a gradation signal are applied associated with image data to the signal electrodes. Then, the electro-luminescence portion is allowed to emit light of a plurality of colors at the same time in pixels after transmissivity of the liquid crystal layers in the pixels reaches a predetermined value. The pixels are located at the intersections between a scanning electrode to which the scanning pulse is applied and the signal electrodes to which the gradation signal is applied.

6927542 - Method of driving an organic electroluminescent display device and display device suitable for said method - Owned by Koninklijke Philips Electronics N.V. (Eindhoven,NL)

A display has a light-emitting layer, such as a light-emitting polymer or a small molecule compound layer, sandwiched between two electrodes structures including an anode structure having a plurality of subgroups of separated anode segments. Each mode segment in each anode subgroup is surrounded by anode segments that are not members of the same anode subgroup. Essentially each anode segment is a member of the anode subgroups. A signal selector assembly is connected to each anode segment, and is arranged to provide the anode segments of a single anode subgroup with image information signals, while holding the remaining anode segments at equal potentials.

7271798 - Liquid crystal exposure device - Owned by Citizen Holdings Co., Ltd. (Nishi-Tokyo,JP)

A color liquid crystal exposure apparatus includes a color light source for emitting a plurality of colored light beams, a liquid crystal shutter having a plurality of liquid crystal pixels arrayed in a direction orthogonal to the direction of the relative movement, and a driving circuit for switching the color light source from one color to another, and for driving the plurality of liquid crystal pixels. The plurality of liquid crystal pixels are divided into a plurality of pixel groups. The liquid crystal pixels in each pixel group are arrayed, one displaced from another by a prescribed distance, in the direction orthogonal to the direction of the relative movement. The driving circuit drives the plurality of liquid crystal pixels in time-division fashion so that the liquid crystal pixels having the same displaced position in the plurality of pixel groups are driven at one time.

7108231 - Adjustment mechanism for a variable-shape wing - Owned by EADS Deutschland GmbH (Ottobrunn,DE)

Adjustment mechanism for adjustment area of variable-shape flow surface with two opposite skin surfaces includes plurality of whirl chambers swivelably arranged next to one another so that the whirl chambers are swivelable relative to one another, and the whirl chambers include lateral stiffening elements and longitudinal stiffening elements.
