摘要： A method and system communicates payload data over a plurality of low voltage differential signaling (LVDS) channels (50). First device (100) transmits the payload data and synchronization information to the second device (150) over N LVDS channels (50), along with a word clock synchronized to the payload data. The second device generates M LVDS receive clocks from the word clock, each having a same frequency that is P times a frequency of the word clock, and each having a different phase. Each of N LVDS receivers (160) of the second device (150): correlates the synchronization data with a reference word using each of the M LVDS receive clocks to produce a correlation value for each of the M LVDS receive clocks; selects a selected LVDS receive clock producing a greatest correlation value; and receives the payload data for the corresponding LVDS channel (50) using the selected LVDS receive clock.

摘要： An electroholographic display system (500) includes a coherent light source (130) adapted to produce a coherent, collimated light beam, a spatial light modulator (SLM) (120) adapted to modulate the light beam, an optical unit (350, 450) in an optical path between the SLM (120) and the image plane (580) where a holographic image is projected. The optical unit (350, 450), which may include a pair of convex lenses (460, 470), operates to effectively decrease the pitch (220) of the pixels (210) of the SLM (120). This allows the electroholographic display system (500) to exhibit a desired range of diffraction even when it includes an SLM (120) whose pixel pitch (220) is larger than would otherwise be required for the desired diffraction range.

摘要： Various methods are described to characterize interferometric modulators or similar devices. Measured voltages across interferometric modulators may be used to characterize transition voltages of the interferometric modulators. Measured currents may be analyzed by integration of measured current to provide an indication of a dynamic response of the interferometric modulator. Frequency analysis may be used to provide an indication of a hysteresis window of the interferometric modulator or mechanical properties of the interferometric modulator. Capacitance may be determined through signal correlation, and spread-spectrum analysis may be used to minimize the effect of noise or interference on measurements of various interferometric modulator parameters.

摘要： Methods and systems for electrical sensing, measurement and characterization of display elements are described. An embodiment includes integrating the electrical sensing, measurement and characterization with the display drive scheme. This embodiment allows for measurement of DC or operational hysteresis voltages and/or response times of interferometric modulator MEMS devices, for example, to be fully integrated with the display driver IC and/or the display drive scheme. Another embodiment allows these measurements to be performed and used without resulting in display artifacts visible to a human user. Another embodiment allows the measurement circuitry to be integrated with the display driver IC and/or the display drive scheme re-using several existing circuitry components and features, thus allowing for integration of the measurement method and its use relatively easily.
