A liquid crystal display device includes: a transparent electrode substrate including a transparent substrate and a transparent electrode, the transparent electrode being formed on one surface of the transparent substrate; a liquid crystal layer; and a pixel electrode substrate including a first layer and a second layer in this order, the first layer including a plurality of pixel electrodes that are located in a region opposed to the transparent electrode with the liquid crystal layer in between, and a first conductive film that is located in a region other than the region opposed to the transparent electrode with the liquid crystal layer in between, the second layer including a second conducive film that is located in a region overlapping the first conductive film. The first conductive film or the second conducive film or both are electrically isolated.

Liquid crystal display device and liquid crystal display

A liquid crystal driver is provided, in which a frame rate of an input image signal is multiplied byN (N is an integer of one or more); each frame is divided into N positive field(s) and N negative field(s) respectively; the image signal is supplied to a liquid crystal panel with a positive polarity in a positive field; and the image signal is supplied to the liquid crystal panel with a negative polarity in a negative field. The liquid crystal driver includes a corrected image signal generator configured to generate a corrected image signal having the same amount of correction added to the positive field and negative field. The corrected image signal is supplied to the liquid crystal panel with the positive polarity in the positive field and the corrected image signal is supplied to the liquid crystal panel with the negative polarity in the negative field.

Liquid crystal driver, liquid crystal driving method and liquid crystal display device

An interconnect structure for a display device includes a driver from which display data are supplied, and an interconnect material having a plurality of signal lines disposed in parallel through which the display data are supplied from the driver. In the interconnect structure for a display device, the signal lines from which the display data are transmitted via the interconnect material are rearranged such that the display data via the signal lines having a comparatively larger effect of the inductance components and the display data via the signal lines having a comparatively smaller effect of the inductance components in the interconnect material are alternately supplied to adjacent pixels or groups of pixels of the display device. As a result, an image is displayed based on the luminance suitable for the display data.

Interconnect structure for display device and projection display apparatus

Disclosed herein is a liquid crystal display apparatus, including, a pixel array section, a first data line, a second data line, a writing unit, a voltage supply control unit, a data line short-circuiting unit, a reading out unit, and a testing unit.

Liquid crystal display apparatus and testing method for liquid crystal display apparatus

An image display device including: a pixel group formed by arranging a plurality of pixels; a driver circuit configured to supply an image signal to each pixel in the pixel group; and a switch circuit configured to shift a destination to which the image signal is supplied in a unit of a pixel pitch by circuit switching for bus lines for transmitting the image signal from the driver circuit to each pixel in the pixel group.

Image display device capable of shifting a data line destination

A winding apparatus capable of improving productivity includes a plurality of sets of winding devices each comprising a nozzle unit and a guide unit, and a plurality of holder for holding a plurality of bobbins in a predetermined posture so that the bobbins are wound with wires parallelly and simultaneously. Further, the nozzle units and the guide units of the plurality of winding devices are arranged on the same guide rails and the supply and winding of the wires are synchronized with the rotation of the holders. Moreover, each of the bobbins used in the winding apparatus is substantially funnel-shaped with the formation of a tapered outer peripheral surface having a projection so that the holders can securely hold the bobbin while positioning the bobbin through this projection. This winding apparatus is suitable for obtaining a saddlelike coil by winding a wire on a deflection yoke bobbin.

Winding apparatus for simultaneous winding of two CRT yokes

An apparatus which includes a nozzle unit, a guide unit, a first winding assemblage and a second winding assemblage, operates such that the first winding assemblage forms a first winding (e.g., a deflection coil on a deflection yoke for use with a cathode ray tube) by moving the wire material from the nozzle unit in a three-dimensional direction after binding the wire material to the workpiece through the guide unit cooperating with the nozzle unit and the second winding assemblage forms a second winding (e.g., a leakage magnetic field shielding coil) different from the first winding by moving the nozzle unit in directions parallel and normal to the axis of the workpiece, respectively. Unlike the conventional apparatus, it is possible to wind a wire material in a variety of ways in different directions while keeping the position of the workpiece in a certain posture.
