Abstract: A simplified pixel display includes a plurality of pixel electrodes, a plurality of storage elements, a single arbitrary voltage supply terminal, a second voltage supply terminal which may be either of the rail voltages of the display, a common electrode, and a plurality of externally controlled switches each selectively coupling an associated one of the pixel electrodes with one of the arbitrary voltage supply terminal and the second voltage supply terminal responsive to a value of a data bit stored in an associated one of said storage elements and to the state of the external control signal supplied to the switch.

Abstract: Methods, apparatus, and systems for generating drive sequences for pulse width modulated displays are described. A pulse width modulated signal that includes a drive sequence of temporal segments that are activated and deactivated to produce a desired gray scale. The temporal segments can be non-binary, non-equally weighted. The drive sequence can also include at least two of the temporal segments are least significant bit segments and the other segments are higher order segments.

Abstract: Methods, apparatus, and pulse width modulating a display include receiving image data and generating pulse data to be written to rows of pixels in a display. The data include a pulse width modulated drive sequence that writes data to selected rows on a first phase of a clock and terminates a write operation on a different row on a second phase of the clock.

Abstract: A multiplexed pixel display includes a plurality of pixel electrodes, a plurality of storage elements, a first voltage supply terminal, a second voltage supply terminal, a common electrode, and a plurality of multiplexers each selectively coupling an associated one of the pixel electrodes with one of the first voltage supply terminal and the second voltage supply terminal responsive to a value of a data bit stored in an associated one of said storage elements. A controller is configured to sequentially write each bit of multi-bit data words to the storage elements, and assert, while each bit is stored in the storage elements, a first predetermined voltage on the first voltage supply terminal, a second predetermined voltage on the second voltage supply terminal, and a third predetermined voltage on the common electrode, for a time dependent on the significance of the stored bit. Various alternate controllers facilitate the use of additional driving schemes.

Abstract: A display system includes a controller for carrying out a data bit modulation sequence for driving a display pixel. The controller applies a plurality of sets of data bits for representing a data word and temporarily dispersing the sets for sequentially writing to the display pixel whereby the display pixel displaying a temporarily dispersed intensity. The display system may be wide varieties of display systems including but not limited to a liquid crystal on silicon display, a digital micromirror display, a plasma panel display, or a direct view liquid crystal device.

Abstract: This invention discloses a proportional to absolute temperature (PTAT) type of temperature measurement to improve the accuracy of temperature measurements. Instead of measuring resistance variations across a distance of diode, a technique of temperature determination using frequency measurements is performed in this invention through a voltage control oscillator. The measurement circuits are more compatible with the use of a flexible PCA connection to the microdisplay to a board. The basic circuit of this invention achieved an improved resistance noise and provides additional operation modes with added benefits of more conveniently and flexibly determining an operation mode to overcome the measurement noises. Furthermore, measurement of frequency as carried out by this invention improves the measurement accuracy and reduces the likelihood of false temperature readings.
