Active OLED Function
Active-Matrix Organic Light Emitting Diode ("AMOLED") Displays function with separated logical and power drive methods. The logic drive is controlled by an integrated display driver ASIC. The power drive to each pixel is isolated utilizing a Thin-Film Transistor ("TFT") layer to the structure
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.
