During an initialization process, a row driver 60 may enable a reset control (CSreset) signal 235 and disable an auto-zero control (CSauto.zero) signal 237. The CSreset signal 235 may transmit to the MRST 228. In response to receiving the CSreset signal 235, the MRST 228 may activate and permit the draining of residual signals from the display of the first image from the sub-pixel 72. These residual signals may drain through to a node coupled to a voltage reset (Vreset) signal 239 designed to encourage draining of the residual signals (e.g., 0 volts), such as a system ground or a system reference voltage. In addition, the row driver 60 may enable a selection control (CSselect) signal 241. The CSselect signal 241 may transmit to the MSEL 224. In response to receiving the CSselect signal 241, the MSEL 224 may activate and permit transmission of voltage data (Vdata) signal 242 to a node of the capacitor 232. To complete the initialization process, the row driver 60 may also enable an initialization control (CSinitialization) signal 243. The CSinitialization signal 243 may transmit to the MINI 220. In response to receiving the CSinitialization signal 243, the MINI 220 may activate and permit initialization of the capacitor 232 to occur. In this state, the capacitor 232 may charge with a voltage corresponding to a voltage difference between the Vdata signal 242 and an initialization voltage (Vinitialization) signal 244. As such, the voltage difference may be programmed through selecting different values for Vdata signal 242 and Vinitialization signal 244 based on a desired voltage level to initialize the capacitor 232 with, while protecting the sub-pixel 72 from receiving additional signals that may interfere with the initialization or that may cause unintentional emissions of light from the LED 230. The row driver 60 may continue the initialization process until the row driver 60 disabled the CSinitialization signal 243 causing the MINI 220 to deactivate.
