Abstract: A light modulator such as an SLM, in which the pixel data array is decoupled from the pixel display array. The pixel data array can be located externally, permitting significant reduction in the circuitry present under each pixel of the display, in turn permitting significant reduction in display pixel size and independent scaling of memory cell size and display cell size.

Abstract: A microdisplay having interface circuitry on the same silicon backplane to allow it to receive digital images and video in a variety of formats and convert same to field sequential color signals for generation of full color images. It includes column data processors having a comparator for each block of N-columns of pixels. Image data is double-buffered in SRAM memory cells located beneath the pixel electrodes, but not within each pixel. The stored data is logically associated with each pixel via the column data processors. Image compression is accomplished by converting RGB data to a variant of YUV data and sampling the color components of the converted data less frequently than the luminance components. The SRAM image buffer consumes a reduced amount of power. A temperature compensation scheme allows the temperature of the microdisplay to be sensed and the drive voltage to the pixel electrodes to be varied in response thereto.

Abstract: A liquid crystal display device with low power consumption is provided by using a driver circuit and a pixel that have novel circuit structures. In a liquid crystal display device using n (n is a natural number and satisfies n≧2) bit digital video signals to display an image, n×m (m is a natural number) memory circuits and n×k (k is a natural number) non-volatile memory circuits are provided in each pixel, thereby giving the device a function of storing m frames of digital video signals in the memory circuits and a function of storing k frames of digital video signals in the non-volatile memory circuits. Once stored in the memory circuits, the digital video signals are repeatedly read out for every new frame to display a still image, so that driving of a source signal line driver circuit can be stopped during still image display. Moreover, digital video signals stored in the non-volatile memory circuits are kept stored after power supply is shut off and hence the image of the stored data can immediately be displayed next time the display device is turned on.

Abstract: The present invention is directed to a display method of performing image display, which comprises outputting corresponding subfield data every plural subfields by pulse width modulation to thereby drive a display element. In driving the display element, rewrite operations of all display pictures are completed in such a manner that subfield data are simultaneously outputted within one field time period, and respective plural subfield data are simultaneously outputted also at any time point within one field time period so that display drive is performed. By employing such display drive, rewrite operations with respect to respective subfields are completed after one field time period is completed. Thus, transfer speed (rate) of data to be transferred in correspondence with the minimum time width can be lowered to much degree as compared to display drive by the conventional subfield system.
