摘要:
A color liquid crystal display device includes at least a liquid crystal display part, and light sources for irradiating the liquid crystal display part with lights of three primary colors, respectively, and performs display of one frame by respective fields of three primary colors and a white field displayed with a mixture of the three primary colors in the liquid crystal display part. The device further includes a circuit for comparing brightness levels of inputted three primary color signals for one frame with each other to define a maximum value thereof as a brightness level of a white signal for one frame; a circuit for setting a proportion of the brightness level of the white signal to be displayed in the white field; and a light source driving part for driving the light sources of the three primary colors so that the white field emits light depending on the brightness level of the white signal and the proportion.
摘要:
A display apparatus and an assembly of a driving circuit for the display apparatus having a display device, a film carrier with a lead to transfer a signal for driving the display device, and a bus board to supply a signal to the lead. A dummy lead is provided along the outside of each of an input side outer lead and an output side outer lead of the film carrier. A predetermined voltage is applied to the dummy leads. The predetermined voltage value is set to a value so as not to stationarily cause a DC bias for the voltage of the outer lead on the outside.

A data transfer method transfers data to an information-side driver for driving a display apparatus. Wherein, driver circuits each comprise a chip address/video data discrimination circuit and a unit driver are mounted around the display apparatus. A unique chip address is set for each of the unit drivers by a hardware pattern. Data exchange with the driver circuits is performed so that chip address information and video data information are time-divisionally transferred to the target unit driver using a chip address/video data common bus line and a chip address/video data discrimination control signal.
摘要:
A display control apparatus receives display data from a display information supply apparatus such as a personal computer, performs predetermined processing of the display data, and transfers the processed data to a display apparatus via a high-speed display image transfer bus so as to display the display data on the display apparatus. When the display information supply apparatus issues a predetermined instruction, the display control apparatus outputs corresponding instruction information to the display apparatus via a second bus arranged in addition to the high-speed bus so as to display the display data in a mode corresponding to the contents of the instruction.

A display apparatus includes a communication device for executing a communication with a host computer via an interface cable. The display apparatus also includes a display having a display screen for displaying image data transferred in synchronism with display timing from the host computer via the interface cable, a connector connectable to the interface cable that communicates with the host computer, and a detector for detecting whether or not the connector is connected to the host computer via the interface cable. A connection/disconnection state of the interface cable is recognized on the basis of the detection result.

An information signal to be fed to an information electrode group is formed of a selection pulse having a pulse width .DELTA.T, a first auxiliary pulse having a polarity opposite to that of the selection pulse and having the same width as that of the selection pulse before the selection pulse, a second auxiliary pulse having a polarity opposite to that of the selection pulse and having the pulse width of one third or less of the pulse width .DELTA.T after the selection pulse, and a third auxiliary pulse having the same polarity as that of the selection pulse and having the pulse width of one third or less of the pulse width .DELTA.T before the first auxiliary pulse. Thus, a driving margin is secured, and a flicker phenomenon is reduced.

Isolated and purified L-proline-4-hydroxylase which catalyzes hydroxylation of L-proline at the 4-position of L-proline in the presence of 2-ketoglutaric acid and a divalent iron ion to produce trans-4-hydroxy-L-proline. The L-proline-4-hydroxylase may be isolated from a microorganism selected from the group consisting of Dactylosporanlium sp. RHI deposited with the National Institute of Bioscience and Human-Technology Agency of Industrial Science and Technology, Japan, under the designation PERM BP-4400 and Amycolatopsis sp.

摘要:
A liquid crystal apparatus is constituted by a display device for data display, a drive circuit unit for driving the display device, a unit substrate for supplying electric signals to the drive circuit unit, and a tape-form film carrier comprising an insulating substrate and a conductor covered with the insulating substrate for connecting the display device, the drive circuit unit and the unit substrate. A part of the film carrier is provided with a blank portion where the insulating substrate is locally removed to absorb a stress applied to the film carrier. A unit substrate constituting the drive circuit unit is screwed to a supporting member so as to allow a movement thereof relative to the supporting member by use of a space regulating means surrounding the screw shank.

Disclosed is a compressor designed to facilitate the assembling of the thrust bearing and reduce noise. A swash plate which moves in responsive to the drive shaft is arranged in a crank chamber defined in a pair of cylinder blocks. Ring washers are held between both bosses of the swash plate and seats formed on both cylinder blocks. Wedge-like clearances are formed between the washers and the seats of the cylinder blocks for the effective introduction of the refrigerant gas by the yawing of the swash plate which occurs as the compressor runs. At this time, the washers, together with the lubrication oil mist contained in the refrigerant gas, constitute the dynamic bearing to support the swash plate and permit the relative movement of the swash plate to the cylinder blocks.

A method of forming an electrical connection from a drive circuit to an electrical device is provided. An electrical connection structure includes: electrodes formed on a device side, electrodes formed on a flexible film carrier having an electrode pattern connected to a drive circuit; and an anisotropic conductive film having metal particles or metal plated particles dispersed therein, interposed between the electrodes on the device side and the electrodes on the flexible film carrier, for electrically connecting the electrodes facing each other through thermocompression bonding. The electrodes, on the flexible film carrier are exposed by removing the flexible film at an electrical connection area, and the length of each exposed electrode is from 1.5 mm to 2.5 mm.
