Principle behind OLED (1/4)

An OLED consists of the following parts:

ƒ Substrate (clear plastic, glass, foil) => supports the OLED ƒ Anode (transparent) => removes electrons (adds electron holes) when a

current flows throu

g

h the device

g

ƒ Organic layers => layers are made of organic molecules or polymers

• Conducting layer transports ‘holes’ from anode

• Emissive layer transports electrons from the cathode

ƒ Cathode (may or may not betransparent) => inject electronswhen a current

flows through the device.

Principle behind OLED (2/4)

•

How do OLEDs emit light?

ƒ A power supply applies a voltage across the OLED ƒ An electrical current flows from the cathode to the anode through the organic

layers

(

actually

this is a flow of electrons)

• The cathode gives electrons to the emissive layers of organic molecules

• The anode removes electrons from the

conductive

layer or

organic

molecules

(this is in fact giving electron holes to

the conductive layer)

ƒ Electrons find electron ‘holes’

at the boundary between the

emissive and the conductive layer, then falling into an energy level of the atom that is missing an electron.

ƒ The OLED emits light ƒ The colour of the light depends on the type of organic molecules ƒ The intensityor brightness depends on the amount of electrical current

applied.

Light

Some insects and other organisms produce organic matter to emit light, but the principle of this luminescence is somewhat different from that of an OLED. An OLED produces light with an electric current, while bioluminescent organisms generally produce light through a chemical reaction (oxidation).

The excited guest molecules emit light, thereby releasing energy and returning to their lowenergy ground state

Types (1/3)

ƒ 1. Passive-matrix OLED (PMOLED)

- Have strips of cathode, organic layers and strips of anode These strips are arranged perpendicular, at the intersections of the cathode and anode. The ‘pixels’ light-up when a current is applied.

ƒ 2. Active-matrix OLED (AMOLED

)

()

- Have full layers of cathode, organic molecules and anode, but the anode layer overlays a thin film transistor (TFT) array that forms a matrix.

- Used for computer monitors, TVs and electronic signs.

ƒ 3. Transparent OLED (TOLED)

Types (2/3)

- Have only transparent components (anode, cathode, substrate). Turned off, they are up to 85% transparent.

- Used for heads-up displays.

- Best suited for active-matrix desi

- Used for TV screens.

ƒ 5. Foldable OLED (FOLED)

Types (3/3)

Have substrates made of very flexible foils or plastics.

ƒ 6. White OLED (WOLED)

- Emit white light that is brighter and more energy efficient than that emitted by fluorescent lights.

- Used for lighting homes and buildings.

Facts about OLED (1/2)

ƒ Thinner, lighter and more flexible than LCD.

ƒ Brighter than LEDs, because the organic layers of an OLED are much thinner than

the corresponding inorganic crystal layers of LCD.

ƒ Do not require backlighting like LCDs and they consume much less power.

This is veryimportant for battery-operated devices.

ƒ Easier to produce and can be made to larger sizes. (printing process)

ƒ Wider viewing angle.

ƒ Lifetime: While red and green OLED films have

Facts (2/2)

ƒ longer lifetimes, blue organics currently have ƒ much shorter lifetimes.
