  • PIXEL CAPACITANCE MEASUREMENT
    Publication number: 20170084233
    Abstract: This disclosure provides systems, methods and apparatus for a capacitance measurement circuit. In one aspect, a circuit can inject charge onto an electrode of a display unit of a display. The circuit can also transfer charge from the electrode to a capacitor to generate a voltage corresponding to a capacitance between the electrode and another electrode of the display unit.

  • Closed loop dynamic capacitance measurement
    Patent number: 9360511
    Abstract: This disclosure provides systems, methods and apparatus for measuring capacitance of a display unit, such as an interferometric modulator (IMOD). In one example, a circuit may include an operational amplifier (op-amp), a voltage controlled current source, and feedback from an output of the op-amp as an input to the voltage controlled current source. An output of the voltage controlled current source may be provided to a display unit as well as an input of the op-amp. A second input of the op-amp may be provided a ramping reference voltage.
