3.08" alphanumeric PMOLED with yellow emission.  Features a reverse-compatible character dispaly interface compatible with historic LCD standard interface and CGRAM for ASCII for a font table.  If migrating from LCD to this PMOLED, there will be no need for backlight power.  LCD displays also require at times a negative voltage for wide temperature operting voltage of liquid crystal fluid.  This voltage is replaced by VCC of the PMOLED which is a positive voltage reference of approximately 12 Volts DC.
