Abstract
Systems, methods and apparatus, including computer programs encoded on computer storage media, are used for driving a display. In one aspect, the method includes connecting a first segment line to a first voltage, connecting a second segment line to a second voltage, and connecting the least a first segment line to the second segment line through at least one inductor. The polarities of segment line voltages may therefore be switched by reusing energy in the system.
Claims32
A method of driving a display including a plurality of segment lines, the method comprising transferring charge between segment lines through at least one inductor.
A circuit for driving a display, comprising:
- a power supply;
- a first segment line;
- a second segment line;
- at least one inductor;
- a first switching circuit configured to selectively connect the first segment line to one of the power supply and the at least one inductor;
- and
- a second switching circuit configured to selectively connect the second segment line to one of the power supply and the at least one inductor.
A circuit for driving a MEMS device in a display including a plurality of segment lines, the circuit comprising:
- a power source selectively coupled to the plurality of segment lines;
- and
- means for transferring charge between segments lines through at least one inductor.
A computer program product for processing data for a program configured to drive a display including a plurality of segment lines, the computer program product comprising:
- a non-transitory computer-readable medium having stored thereon code for causing a computer to:
- transfer charge between segment lines through at least one inductor.
