    摘要: In accordance with the present invention, a passive liquid crystal display cell includes a first substrate having a light absorbent material patterned thereon. A first conductive material is formed in a position relative to the light absorbent material for forming one of a data line and a gate line. The position may be over the light absorbent material or below the light absorbent material (and may include transparent layers in between). A second conductive material is spaced apart from the first conductive material by a gap. The gap includes liquid crystal, and the second conductive material forms the other of the data line and the gate line. A pretilt control structure is formed adjacent to the liquid crystal. The gate line and the data line provide an electric field therebetween wherein the pretilt control structure provides pretilt for the liquid crystal to provide a wide viewing angle.

    摘要: A liquid crystal display with an array of pixels comprises a liquid crystal layer having transparent electrodes on either side thereof with an alignment layer disposed on each of the electrodes and in contact with opposite surfaces of the liquid crystal layer. The alignment layers are capable of inducing a predetermined pre-tilt angle on the molecules of the liquid crystal. The pre-tilt angle inducing ability of at least one of the alignment layers, which is formed with only one alignment direction, has been selectively altered so that pre-tilt angle inducing ability in the altered area differs in the magnitude of the angle from the pre-tilt angle inducing ability of the unaltered area. With the liquid crystal molecules having at least two different pre-tilt angles, more than one domain is created when voltage is applied across the electrodes. The change in the pre-tilt angle inducing ability in the altered areas is achieved by exposure to a beam, such as ultra violet light, of sufficient energy. In the preferred embodiment, the display is an active type with twisted nematic liquid crystals.

    摘要: An electronic matrix system and method for rapidly storing and efficiently retaining electric charge in selected ones of a plurality of storage elements are disclosed. Each storage element is addressable through a pair of parallel row select address lines and a column address line. A pair of threshold devices are coupled in nonopposing relation between the row select address lines and the storage element is coupled between the common node of the threshold devices and the column address line to which charging potential is applied. During the charging of the storage element, operating potentials which are substantially equal and opposite in polarity are applied to the row select line pair to forward bias both threshold devices and thereafter operating potentials which are also substantially equal and opposite in polarity are applied to the row select line pair to back bias both threshold devices to provide retention of the charge in the storage element.

    摘要: A light influencing display is provided which has a plurality of pixel group, each pixel of which includes a first electrode formed on a first surface and an opposing, second electrode formed on a second surface. A separate three terminal control device of deposited semiconductor material is formed on the first surface in association with each pixel. Each control device has a control terminal and two current path terminals, a first of which is connected to the first electrode of the control device's associated pixel. A voltage supply lead is formed on the first surface in association with each pixel group, and is connected to the second current path terminals associated with its pixel group. Similarly, a control lead is formed on the first surface in association with each pixel group, and is connected to the control terminals associated with its pixel group. A plurality of conductive data leads is formed on the second surface, with a data lead being electrically connected to each second electrode of a given pixel group. As a result, a desired voltage can be applied between the electrodes of a given pixel by using a selected control lead to turn on the control devices of that pixel's pixel group, and by using a selected data lead to supply a data voltage to its second electrode. The present invention allows x - y addressing of an active matrix display without crossing address lines on either the first or second surface, avoiding the risk of short circuits between such lines. It also allows the voltage supply and control leads associated with adjacent pixel groups to be combined, greatly reducing the number of lines required in such a display.

    摘要: An alignment-film in which the pretilt angle is changed by ultraviolet irradiation, a material for forming the same, a liquid crystal display device using the alignment film, a method for producing an alignment-film formation material, and a method for producing an alignment film. Ultraviolet irradiation causes large changes in pretilt angle but few changes in electrical characteristics, and a liquid crystal display device free from deterioration of the liquid crystal, image sticking, or the occurrence of flicker results. A first polymer forms the underlying principal layer and a second polymer forms thereon a surface layer thinner than the principal layer. The first polymer may exhibit a small change in electrical characteristics due to ultraviolet radiation and the second polymer may exhibit a large change in pretilt angle due to ultraviolet radiation.

    摘要: A liquid display comprises a first substrate having a plurality of electrodes thereon, a second substrate having a common electrode, and a liquid crystal material disposed between the first substrate and the second substrate. The common electrode has a pattern of openings therein which causes display elements of the display to have more than one liquid crystal domain. The common electrode is otherwise continuous, except where the pattern of openings is located. The liquid crystal display is of the active matrix variety. It may be a multi-domain homeotropic liquid crystal display or a multi-domain twisted nematic liquid crystal display. It may be a crossover type of display wherein gate lines and data lines are disposed on one substrate and insulated from one another at crossover regions, or a non-crossover type with gate lines, pixel electrodes and active devices on one substrate and data lines having a pattern of openings in accordance with the invention on the opposite substrate.
