摘要： A display apparatus is constituted to have a multiplicity of pixels each divided into at least two sub-pixels having mutually different areas including a larger sub-pixel having a larger area and a smaller sub-pixel having a smaller area. Each sub-pixel is provided with a transparent electrode and a low-resistivity conductor connected to the transparent electrode, and the low-resistivity conductor for the larger sub-pixel is set to have a lower resistance than the low-resistivity conductor for the smaller sub-pixel. As a result, a pixel switching characteristic can be uniformized over an entire picture area of the display apparatus regardless of different areas (loads) of the sub-pixels and without using different performances of drivers.

摘要： A liquid crystal device of the type comprising a pair of substrates and a chiral smectic liquid crystal disposed between the substrates so as to form at least one pixel, is driven by a driving method including applying a signal waveform to a selected pixel. The driving method includes the step of applying the signal waveform which includes a clear pulse for placing the liquid crystal in a first state and a writing pulse subsequent to the clear pulse for selectively placing the liquid crystal in a second state depending on input data. The writing pulse includes a higher voltage portion and a pair of lower voltage portions sandwiching the higher voltage portion. The writing pulse is effective in reducing power consumption while ensuring a wider drive margin.

摘要： A liquid crystal device of the type including a pair of substrates having thereon a group of scanning electrodes and a group of data electrodes, and a chiral smectic liquid crystal disposed between the substrates so as to form a pixel at each intersection of the scanning electrodes and the data electrodes, is driven by a driving method causing less crosstalk. The driving method includes the steps of sequentially applying a scanning selection signal to the scanning electrodes, and applying data signals to the data electrodes in synchronism with the scanning selection signal. The scanning selection signal includes a writing pulse having a pulse width .DELTA.T for determining an optical state of the chiral smectic liquid crystal in cooperation with a data signal. Each data signal includes a data pulse for determining an optical state of the chiral smectic liquid crystal in cooperation with the writing pulse. A plurality of data signals are each designed to have a waveform determined based on a combination of data applied to pixels on at least two consecutively selected scanning electrodes. At least one of said plurality of data signals include an auxiliary pulse having a pulse width shorter than .DELTA.T.

摘要： A liquid crystal device of the active matrix-type having two-dimensionally arranged pixels along rows and columns is driven frame by frame. In each frame operation, a scanning selection period (TG) for each selected row is divided into a first period (t1) and a second period (t2). In t1 of a current frame (TF2), a reset pulse is applied to a pixel concerned, and the reset pulse is set to have an absolute value of voltage identical to and a polarity opposite to those of a writing pulse voltage applied to the pixel in the previous frame (TF1). Then, in t2 of the current frame (TF2), the pixel is supplied with a writing pulse depending on a prescribed display state of the pixel for the current frame. As a result, the reset period is shortened to favor a high-speed display and a higher resolution display.

摘要： An active matrix-type liquid crystal panel is driven for a motion picture display in a succession of frame periods to provide an improved motion picture quality without causing a lowering in luminance or contrast, or a display irregularity over the panel due to a signal transmission delay along the panel electrodes. In the driving method, each frame period is divided into a plurality of sub-frame periods including at least one preceding sub-frame period and a final sub-frame period so that said at least one preceding sub-frame period provides a total period which is shorter than the final sub-frame period; the active elements along the rows of pixels are sequentially selected row by row at respective selection periods in each sub-frame period; and the liquid crystal at each pixel is supplied with a voltage in a selection period of each preceding sub-frame period which is lower than a voltage applied to the liquid crystal at the pixel in the final sub-final period.
