  • Patent number: 8373729
    Abstract: A technique for reducing the kickback voltage error between two or more common voltage signal lines in a display device is provided. The kickback voltage error may be caused by driving a first and second common voltage at different levels. In one embodiment, a common voltage offset may be applied to the second common voltage such that the magnitude of the voltage kickback error is approximately equalized at the maximum and minimum pixel voltages for pixels coupled to the second common voltage. A data voltage offset, which may be determined based upon gray level data, may be applied to the data voltage supplied to the pixels coupled to the second common voltage. The foregoing technique may compensate for the kickback voltage error between the first and second common voltage lines, thereby reducing visual artifacts and improving color accuracy of the display.

  • Patent number: 8368725
    Abstract: Methods and systems for improved optical efficiency and brightness of display systems are provided herein. Embodiments use laser light sources in substantially continuous mode, thereby increasing the maximum overall output of an optical system. Embodiments exploit the small étendue of laser sources to lower the loss of throughput of an optical system. Embodiments enable a scrolling color scheme that allows a display system to be illuminated with two or more colors at any given time, thereby increasing the brightness of the display system. Embodiments can be used with liquid crystal displays and/or digital mirror displays. Embodiments can be used in single-panel and/or two-panel display systems.

  • Patent number: 8274468
    Abstract: A flat panel display includes first and second signal drivers which drive a first and second group signal lines of a display panel in accordance with an input first and second group video data respectively. A controller controls a timing of sending the first group video data to the first signal driver via the first data line, and a timing of sending the second group video data to the second signal driver via the second data line. A delay time generating section shifts a relative timing between a timing at which the first signal driver receives the first group video data and a timing at which the second signal driver receives the second video data by a determined time. The problem of the deterioration of the EMI caused by synchronization of the peak currents respectively generated in signal drivers for driving a flat panel display can be suppressed.
