SYSTEM AND METHOD OF SENSING ACTUATION AND RELEASE VOLTAGES OF INTERFEROMETRIC MODULATORS |
摘要 |
This disclosure provides methods and apparatus for calibrating display arrays. In one aspect, a method of calibrating a display array includes determining a particular drive response characteristic and updating a particular drive scheme voltage between updates of image data on the display array. The drive response characteristic may be determined by applying a ramped voltage to a line of the array and detecting a current pulse due to a capacitance change on the line. The drive response characteristic can be determined based on data representing a width of a current pulse in the waveform or a weighted or unweighted area of a current pulse in the waveform. |
