Active vs. passive matrix is explained in popular science websites as simultaneous turning on-off, one row or one pixel at a time or power efficiency. But how are they related to "matrix" active or passive? Besides, not all LED were turned on along a single line in any given time in PMOLEDs' picture. Why?
Also provide some suitable textbook or research reference to introduction to organic electronics, And more importantly, mention prerequisite knowledge.
The article link https://www.oled-info.com/pmoled-vs-amoled-whats-difference makes not much information, and meaning of "active" and "passive" matrix
My guess would be that the terms are about OLED screens for TV or similar matrices, not about single OLEDs.
Dear Sumit,
The difference between pessive matrix OLEDs and active matrix OLEDs is the driving electronics. There is an article that explains very well. Please see the following link.

Hope it helps.
Dear Sumit,
The colleagues hinted the answer but i want to add some elaborate definitions. Passive and active do not concern the Led it self. It concerns the display matrix of the optical display. If the display does not contain amplifiers to drive the LEDs it will be passive and vice versa.
Generally the term passive means not containing amplification.
while active means it contains amplifiers. The amplifiers may be called also drivers.
As for the education my advice is to study:
- Semiconductor materials with emphasis to the organic semiconductors
- Semiconductor devices including diodes and transistors
- Basic electronic circuits both analog and digital.
- Optoelectronics
A s a basic book you can refer to the book: Book Electronic Devices
