摘要： A reflective liquid crystal display apparatus has a liquid crystal display part composed of at least a liquid crystal layer and a pair of polarizers holding the liquid crystal layer therebetween, for display of bright and dark states in a mode of transmitting and shielding external light in a direction approximately normal to a display plane, and a reflecting part for reflecting the external light which has been transmitted through the liquid crystal display part. The liquid crystal display part has a property where it can transmit external light in a designated direction other than in a direction approximately normal to the display plane even in a mode of shielding the external light, and the reflecting part reflects the external light received in the designated direction so as to transmit the external light once again through the liquid crystal display part in a direction approximately normal to the display plane.

摘要： A reflective liquid crystal display device has a liquid crystal cell formed by laminating upper and lower orientation layers 11 and 21, upper and lower electrodes 14 and 24, upper and lower substrates 12 and 22, and upper and lower polarizers 13 and 23 arranged in order above and below a liquid crystal layer 10 so that they may face their counterparts respectively. The liquid crystal cell is provided with viewing angle dependence so that the light transmission ratio of the dark display section to the bright display section for the light incident at the required angle may be less than 2 at the required azimuth angle of the liquid crystal cell, and the direction of the required azimuth angle is aligned with the direction of the main light source incident into the liquid crystal cell.

摘要： The object of the invention is to provide a drive method suitable for driving a fast-responding STN liquid crystal display device which ensures a minimized cross talk and improved contrast in display. The drive method comprises a memory means for storing display data corresponding to a plurality of lines, a function generating means for generating a drive function for the row electrodes, an arithmetic means for computing the outputs from the foregoing means, a column electrode drive means for driving the column electrodes in dependency on the output from the arithmetic means, and a row electrode drive means for driving the row electrodes in accordance with respective row electrode drive functions. As a voltage function to be applied to each row during drive operation, a sum of a plurality of orthogonal functions is utilized. Thereby, degradation in contrast due to display patterns as well as the cross talk can be minimized. Further, arithmetic operation can be simplified in gradation display since application of a compensating voltage waveform is no more required.

To achieve the above object, the liquid crystal display of this invention comprises a plurality of parallel display electrodes 40-n wired over the electrode substrate 311 (312); terminals 41-n for the electrodes 40-n led out to the end portion of the electrode substrate 311 (312) and connected to TCPs, the terminals 41-n having pitches smaller than those of the electrodes 40-n; and leadout wirings 331 (332) for connecting the electrodes 40-n and the terminals 41-n. The leadout wirings 331 (332) each consist of a portion extended from the respective electrode 40-n as it is, a portion extended from the respective terminals 41-n as it is, and almost parallel, inclined linear wiring 42-n that connects the two extended portions. The length of the two extended portions and the width of the inclined linear wiring 42-n are adjusted so that the wiring resistances of the individual leadout wirings 331 (332) are almost the same.

摘要： An amplification MOSFET in a source ground form receives at its gate an output signal of a source-follower circuit through a second capacitor. The source-follower circuit, on the otherhand, receives a voltage of a first capacitor which receives a signal charge. A predetermined bias voltage is supplied to the gate of the amplification MOSFET through a switch device while the signal charge of the first capacitor is reset. According to this structure, the second capacitor can transmit only the signal component and the voltage signal itself can be amplified by the source ground type amplification MOSFET. The amplification MOSFET can be biased to its optimum operation point by the switch device during the reset period of the first capacitor; hence, sensitivity can be substantially improved with a simple circuit structure.

摘要： An improved multi-color liquid crystal display system which is capable of making visual color representation of more than eight colors in a display panel, such as a liquid crystal display panel which is composed of liquid crystal cells having three primary color filters attached thereto. Lightness of a cell is controlled by causing the cell to be in "ON" state during M frames out of N frames (N>M) to thereby provide half-tone color representation of the cell. This enables increase of the number of colors represented with the three primary color cells more than eight by combining "ON", "OFF" and the "half-tone" states of the three primary color cells.
