Circuits for controlling display apparatus

A method for actuating an array of light modulators, comprising:

• storing a data voltage in each data storage element of an array of data storage elements, each data storage element in the array of data storage elements corresponding to a light modulator of the array of light modulators, each light modulator including a first actuator configured to drive the light modulator into a first state and a second actuator configured to drive the light modulator into a second state;
• and
• adjusting, for each light modulator in the array, an actuation voltage on a single actuation voltage interconnect coupled to the light modulator to:
• apply a first drive voltage to the first actuator of the light modulator,
• apply a second drive voltage to the second actuator of the light modulator, and
• control an application of the data voltage stored in the data storage element corresponding to the light modulator to a latch circuit coupled to the light modulator to control the application of the first and second drive voltages to the first and second actuators of the light modulator, respectively.

A display apparatus comprising:

• a data storage means for storing a data voltage corresponding to a light modulator;
• a first actuation means for driving the light modulator into a first state;
• a second actuation means for driving the light modulator into a second state;
• and
• a single actuation voltage interconnect, for:
• applying a first drive voltage to the first actuation means,
• applying a second drive voltage to the second actuation means, and
• controlling a data voltage application control means for controlling the application of the data voltage to a latch circuit to control the application of the first and second drive voltages to the first and second actuation means, respectively.
