After reading the bit, the row driver 60 may determine if the bit the last bit of the stored DATA 412 (block 471). The row driver 60 determines if the last bit has been read and/or transmitted to analog driver circuitry 442. A row driver 60 may mange this determination through a variety of ways, for example, maintaining a counter that increments in tandem with enabling of Sel signal 415 to indicate when the row driver 60 has read an expected number of bits from the memory circuitry 400.
If the bit is the last bit, the row driver 60 may complete the display cycle (block 427). The display cycle may include the whole process 461 such that upon reaching block 427, the row driver 60 has emitted the gray level of light corresponding to the DATA 412. Upon completing the display cycle, the row driver 60 may be ready to accept new DATA 412 corresponding to a same or different gray level for emission.
