摘要： An active matrix liquid crystal display device has a plurality of unit pixels being arranged in a matrix configuration, each unit pixel being divided into a plurality of subpixels. Each of the subpixels has a subpixel electrode, a pixel transistor connected to the subpixel electrode, and a voltage controlling capacitor connected to the subpixel electrode. A voltage controlling capacitor line for supplying a compensation voltage signal is connected to the voltage controlling capacitor so that after the writing to the subpixel has been completed, the potential of the compensation voltage signal is varied to modulate the potential of the subpixel electrode to be a predetermined voltage, using the voltage controlling capacitor. Such combining of spatial dithering attained by a pixel-dividing technique and a capacitively-coupled driving method eliminates the need for digital-to-analog converter circuits, attains gray scale display based on a digital image signal, and achieves a reduction in power consumption.

摘要： In a buffer that outputs an analog voltage Vout to be applied as a driving voltage to a pixel capacitance in a display region of an active-matrix liquid crystal display device, a CMOS circuit for generating this analog voltage includes four Pch transistors (QP0 to QP3) connected in parallel and four Nch transistors (QN0 to QN3) connected in parallel. When charging the pixel capacitance, a bias current is reduced and the driving capability is lowered by control with selector switches (SP1 to SP3) at a time at which the large driving capability at the beginning of the charging is not necessary anymore. And when discharging the charge that has accumulated at the pixel capacitance, the bias current is reduced and the driving capability is lowered by control with selector switches (SN1 to SN3) at a time at which the large driving capability at the beginning of the discharging is not necessary anymore. With this configuration, it is possible to reduce the power consumption of the output buffer applying the analog voltage for image display to the capacitive load in the display panel.

The data register is used to store optional data in response to a control signal, to overwrite the stored optional data with display data, and to prepare display data for a given line of the display panel. The data prepared in the data register is transferred to the display panel to display the given line of the display panel. The drive circuit is capable of supplementing display data if the display data is improper for the display, thereby securing the quality of the displayed images.

摘要： A scan driving circuit and a display device, the display device including display elements two-dimensionally disposed in a matrix; scanning lines, initialization control lines, and display control lines extending in a first direction; and data lines extending in a second direction different from the first direction. The scan driving circuit includes a shift register portion and a logic circuit portion, and generates scan signals and initialization signals, both based on two or more enable signals, and control signals. The scan driving circuit is configured such that changing the width of a start pulse (and thereby the ratio of a light emitting period to a non-light emitting period) does not affect the scan signals or the initialization signals.

摘要： The scanning signal line driving circuit sequentially carries out active driving with respect to each set of a certain number of scanning signal lines which are adjacent to each other in a vertical direction, and when carrying out an actual writing with respect to a first set of a certain number of pixel lines adjacent to each other in the vertical direction, carries out pre-charging with respect to a second set of the certain number of pixel lines to which the actual writing is carried out next with a potential of a same polarity as that of the first set of the certain number of pixel lines. In this manner, it is possible to provide a matrix image display device with no irregularities in display quality and is capable of matching the apparent vertical resolution of the device to that of the image source, when using an image signal of vertical resolution lower than the maximum physical vertical resolution of the device.
