OLED glossary

AMOLED

Active Matrix OLEDs. The Active matrix of AMOLED displays enables high resolution and large displays, from wearable to TV sizes. AMOLEDs are also more power-efficient than PMOLED displays.

Flexible OLED

Flexible displays, which can be flexible, foldable, rollable or stretchable (depends on the flexibility properties) enable new applications for displays.

LTPS

Low Temperature Poly Silicon, or LTPS, is a manufacturing process for making TFT backplanes for LCDs or AMOLED displays. The high-performance ofLTPS (compared to a-Si TFTs) backplanes enable the high-end displays used in smartphones, wearables and tablets.

OVPD

Organic Vapor Phase Deposition - an OLED production technology, which can reduce the cost and increase the efficiency of the OLED production process, developed by Universal Display and licensed exclusively to Aixtron (now APEVA). The OVPD production process utilizes a carrier gas stream in a hot walled reactor at very low pressure to precisely deposit the thin layers of organic materials used in OLED displays.

PHOLED

Phosphorescent OLED, a proprietary technology by Universal Display, PHOLED use small molecule phosphorescent materials to create OLEDs and are in wide use today in all AMOLED displays on the market.

PMOLED

Passive Matrix OLEDs. PMOLEDs are more simple to make compared to AMOLEDs, but require more energy and are restricted in their size and resolution.

TOLED

TOLED means Transparent OLEDs. These displays enable innovative displays in commercial, retail and other markets.

UDC

Universal Display Corporation (UDC) - an OLED research, materials and IP company. UDC holds the basic patents for phosphorescent OLEDs.
