The row driver 60 may precharge a comparator 490 after initializing the memory circuitry 492 (block 524). To precharge the comparator 490, the row driver 60 may enable a precharge signal to cause a voltage to boost the circuitry, thus enabling the sub-pixel 72 to be more responsive to changes in output from the comparator 490. To precharge the comparator 490, the row driver 60 may enable a “Precharge” signal that works in conjunction with an inverse emit_en signal 420 to cause a voltage (e.g., DVDD) to transmit through to the comparator 490 (e.g., the MTCH node of the comparator 490) to boost the circuitry. Although specific circuitry is depicted that operates to precharge the comparator 490 in response to the Precharge signal, it should be appreciated that a variety of valid circuitry arrangements may be used to facilitate precharging the comparator 490.
