This disclosure provides systems, methods and apparatus for providing voltages to an arrangement of display modules in a display. In one aspect, a group including multiple rows of display modules may be provided a reset signal at the same time. Each row may be provided its own driver circuit to provide a row enable signal such that each row of display modules in the group may be biased row-by-row following the reset. Additionally, driver circuitry providing a variety of voltages to the display modules may be implemented in chip-on-glass (COG).
