/* Working of OLED'S */
* Cathode (may or may not be transparent depending on the type of OLED) - The cathode injects electrons when a current flows through the device.

*OLEDs emit light in a similar manner to LEDs, through a process called electrophosphorescence.
*The process is as follows:
#The battery or power supply of the device containing the OLED applies a voltage across the OLED.
#An electrical current flows from the cathode to the anode through the organic layers (an electrical current is a flow of electrons).
