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

panels.

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.
