In the depicted embodiment, the cathode of a LED 230 is coupled to a reference voltage (Vreference) signal 470 and the anode of the LED 230 is coupled to a reference voltage (Vreference) signal 473 through MS 226A, MS 226B, MS 276, and MS 278. As explained earlier, after DATA 412 is stored in the memory circuitry 400C and, in some embodiments, after precharging circuitry via Precharge signals 416, the row driver 60 may enable Emit_en signal 420 to cause light emission. Upon activation of MEM 480 and MEM 482, a stored DATA 412 bit transmits through the sense amplifier 440 and the amplified bit transmits to the MEM 480 while an inverted version of the stored DATA 412 bit transmits to MEM 482 without amplification. The inverted bit and the amplified bit are used as control signals to activate the MS 226A and 226B, effectively acting like the CSimage.data signal 247 from previous discussions. Upon activation of the MS 226A and MS 226B, analog driver circuitry 442 generates a driving current based at least in part on the voltage difference between Vreference signal 473 and Vreference signal 470 to transmit through a LED 230 to cause light emission.
