INTRODUCTION
Active-matrix OLED (Active-matrix organic light-
emitting diode or AMOLED) is a display technology
used for mobile devices and televisions.
OLED describes a specific type of thin film displaytechnology in which organic compounds form the
electroluminescent material.
Amoled screens are are ultra thin,ultra bright,and
doesnt require a backlight to work.

MICROSCOPIC IMAGE OF SCREEN
Pixels that are integrated onto a Thin Film Transister(TFT)
Two primary TFT are
1.Polycrystalline silicon(poly-Si)
2.Amorphous silicon(a-Si)

SCHEMATIC OF AMOLED
An active matrix OLED display consists of a
matrix of OLED pixels.
Current flow is controlled by at least two TFTs
at each pixel
One to start and stop the charging of a storage
capacitor
Second to provide a voltage source at the level
needed to create a constant current to the pixel
These technologies offer the potential for
fabricating the active matrix at low temperatures
(below 150C).

AMOLED In-Cell Touch Panels
Manufacturers have developed in-cell touch panels,
integrating the production of capacitive sensor arrays
in the AMOLED module fabrication process.
In-cell sensor AMOLED fabricators include AU
Optronics and Samsung.Samsung has marketed their
version of this technology as Super AMOLED.

APPLICATIONS
Well suited for portable
devices.
Like Mobiles.
AMOLED comes in
more medium and large
size application.Flexible display also
adopt in AMOLED

ADVANTAGES
Active-matrix OLED displays provide higher refresh
rates and they consume significantly less power.
AMOLED pixel turn on and off more than three
times faster than the speed of conventional motionpicture film.
Amoled is flexible and can be used easily.
Superior Image quality.

CONCLUSION
I would like to conclude that this technology is moreflexible, easy to use and would grow up as definitemedium of displays. An amoled display consumesless power and offers a high refresh rate with superiorimage quality. They are flexible and unbreakable innature
All the above factors make it perfect blend tobecome one of the top most displays in the comingfuture.
This is latest technology that would createwonders in the coming feature.
