摘要： A deformable mirror device having a two-dimensional array of mirror elements is driven in such a way to reduce the data rate and remove the need for buffer stores. The mirror elements are loaded row-by-row in response to an n bit video signal in 2n loading operations. Only n rows are loaded in each loading operation, the other rows remaining in their previous conditions, and the loading continues sequentially down the array. The timing of the loading is such that the duration from loading a given row with a first data bit to loading the same row with the next data bit is proportional to the significance of the first data bit.

摘要： An active matrix display device is disclosed which realizes changing over between a wide display and a normal display with a simple construction. The active matrix display device includes picture elements disposed in rows and columns on a horizontally elongated screen. A gate line is connected to each picture element row while a data line is connected to each picture element column. A signal line for supplying a video signal and data lines are connected by way of sampling switches. A horizontal shift register controls sequential opening and closing operations of the sampling switches. The picture element columns of the horizontally elongated screen are divided into a predetermined area allocated to a normal display and a pair of expansion areas included in a wide display. The horizontal shift register is divided into a predetermined stage section corresponding to the predetermined area and expansion stage sections corresponding to the expansion areas. Upon wide display, the predetermined and expansion stage sections of the horizontal shift register are interconnected serially into an integrated condition, but upon normal display, the expansion stage sections are disconnected from the predetermined stage section.

摘要： So as to make a composing unit (R7, 33) produce a composite signal of a drive voltage for use in producing a driving signal for an LCD having a liminance versus drive voltage characteristic curve approximated by a nonlinear curve generated by a concatenation of at least first through third linear function curves, an analog nonlinear operation circuit (15) comprises first through third amplifier circuits (31(1) - 31(3)) for generating first through third function voltages in correspondence to the first through the third linear function curves. The amplifier circuits are typically differential amplifiers particularly when the operation circuit is applied to gamma compensation of television video signal for a CRT into a gamma compensated signal which is for the LCD and is produced as the composite signal. In this event, the amplifier circuits are supplied in common with the video signal and respectively with low, middle, and high reference voltages defined by white, intermediate, and black levels of the video signal.

摘要： This invention relates to gradation display by pulse width control method (PWM method) in each pixel in a capacitive display apparatus such as electroluminescent liquid crystal display apparatus. The driving voltage applied to the data electrodes is caused to vary in a ramp waveform, and the number of gradations of gradation display by the PWM method is increased. Since the capacitive display apparatus is used, the driving pulse is increasingly influenced by capacity as the location of the pixel to be controlled is further away from the drive circuit of the data electrode and in particular its duration becomes extended. As a result, even for identical gradation data, uneven illumination may occur. In this invention, the pulse width applied to the data electrodes is gradually decreased as scanning of the electrodes progresses. Therefore, the brightness of the capacitive display apparatus may be made uniform over the entire screen surface. Also, in the invention an impedance converting means connected in series between a DC power supply and the data electrodes is controlled by a control signal, with a switching means being controlled to effect application of a current to the data electrode for a period according to gradation display data.
摘要翻译：本发明涉及在诸如电致发光液晶显示装置的电容显示装置中的每个像素中通过脉宽控制方法（PWM方法）进行的等级显示。施加到数据电极的驱动电压以斜坡波形变化，并且通过PWM方法的灰度显示的灰度数增加。由于使用电容显示装置，随着待控制像素的位置远离数据电极的驱动电路并且特别是其持续时间变长，驱动脉冲越来越受电容影响。结果，即使对于相同的灰度数据，也可能发生不均匀的照明。在本发明中，施加到数据电极的脉冲宽度随着电极扫描的进行而逐渐减小。因此，电容显示装置的亮度可以在整个屏幕表面上均匀。而且，在本发明中，通过控制信号来控制串联连接在直流电源和数据电极之间的阻抗转换装置，其中控制开关装置以根据灰度等级向数据电极施加电流显示数据。
