Abstract
An electronic display row drivers or column drivers that send reference currents or voltages to microdrivers to be used to drive micropixels to particular levels. The microdrivers, in turn, ship current to micropixels that display images based at least in part on the shipped current.
Claims23
An electronic device comprising:
- a plurality of row drivers configured to receive an electrical charge;
- a plurality of microdrivers, wherein at least one microdriver of the plurality of microdrivers is configured to receive a reference current from at least one of the plurality of row drivers, wherein the reference current is based at least in part on electrical charge, wherein the at least one of the plurality of row drivers is configured to ship the reference current through the at least one microdriver through a row of the plurality of microdrivers to at least two microdrivers in a column of microdrivers of the plurality of microdrivers, wherein the column is orthogonally arranged respective to the row, wherein each of the at least two microdrivers are configured to drive a plurality of micropixels corresponding to a respective microdriver of the column using the shipped reference current;
- and
- the plurality of micropixels configured to emit light in a pattern based at least in part on the reference current received from the plurality of microdrivers.
