Abstract
This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for reducing common line write time in a display. In one aspect, a common line write waveform shape is based at least in part on the distance a given common line is from a segment driver circuit.
Claims28
A method of updating a display, the display comprising a plurality of display elements arranged in common lines and segment lines, wherein the display elements in a respective common line are updated by providing data to each of the segment lines and by applying a waveform within a write window to the respective common line, the method comprising:
- generating a waveform within a write window associated with a particular common line, wherein the shape of the waveform is based, at least in part, on a position of the particular common line in relation to a segment driver circuit;
- and
- applying the waveform to the particular common line.
A display apparatus comprising:
- a set of segment lines;
- a segment line driver circuit configured to apply data signals to the set of segment lines during a series of write windows;
- a set of common lines, at least some of which have different distances from the segment line driver circuit;
- a common line driver circuit configured to sequentially apply a write waveform to different ones of the set of common lines during different ones of the series of write windows;
- wherein the common line driver circuit is configured to apply a write waveform of a particular shape to a common line of the set of common lines, and wherein the shape is based at least in part on the position of the common line with respect to the segment driver circuit.
A display apparatus comprising:
- a set of segment lines;
- a segment driver configured to apply data signals to the set of segment lines during a series of write windows;
- a set of common lines, at least some of which have different distances from the segment line driver circuit;
- means for applying a write waveform of a particular shape to a common line of the set of common lines during one of the series of write windows, wherein the shape is based at least in part on the position of the common line with respect to the segment driver circuit.
A computer readable medium having stored thereon instructions that, when executed by processing circuitry, cause a display driver circuit to:
- generate a waveform within a write window associated with a particular common line, wherein the shape of the waveform is based, at least in part, on a position of the particular common line in relation to a segment driver circuit;
- and
- apply the waveform to the particular common line.
A method of updating a display, the display comprising a plurality of display elements arranged in common lines and segment lines, wherein the display elements in a respective common line are updated by providing data to each of the segment lines and by applying a waveform within a write window to the respective common line, the method comprising:
- generating a waveform within a write window associated with a particular common line, wherein the shape of the waveform is based, at least in part, on a signal travel time between a segment driver circuit and the particular common line;
- and
- applying the waveform to the particular common line.
