Passive OLED Function
Passive-Matrix Organic Light Emitting Diode ("PMOLED") Displays function with logical and power drive through a single Anode & Cathode pair. The device will multiplex all rows & column multiplexing by scanning.
The anode and cathodes are arranged in perpendicular arrays on the top and bottom layers. The Electron Transport Layer ("ETL") facilitates the charge carrying electrons from the cathode. The Blocking Layer ("BL") is used to contain electrons towards the Emissive Layer ("EL"). The EL is a series of Positive & Negative material deposits ("P-N") that with current drive emit light. The Hole Transport Layer ("HTL") receives holes from the emissive layer and the corresponding Hole Injection Layer ("HIL") receives the holes from the Anode.
