OLED glossary

AMOLED
Active Matrix OLEDs. These OLEDs are more power-efficient. Theoretically they should also be cheaper than TFT-LCD to produce. Everyone agrees that AMOLED will have the lion share of the OLED market.

CDT
Cambridge Display Technology (CDT) is the leading developer of technologies based on polymer light emitting diodes (PLEDs).

FOLED
FOLED means Flexible OLED. This is a proprietary technology by UDC. Quoting from the web page - FOLEDs are organic light emitting devices built on flexible substrates. Flat panel displays have traditionally been fabricated on glass substrates because of structural and/or processing constraints. Flexible materials have significant performance advantages over traditional glass substrates.

LTPS
Low Temperature Poly Silicon a leading-edge manufacturing process for making TFT LCDs or OLEDs. It features the technology of laser annealing, which achieves crystallization of silicon film with substrate temperature blow 400°C. Advantages of LTPS - Faster Electron Response, Less connections & components, Low power consumption and itegration of driver ICs onto the substrate

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 by UDC. 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. This is a proprietary technology by UDC. PHOLED use soluble phosphorescent small molecule materials to create OLEDs. It was originally developed for Mobile Phone displays, but it also promoted as a general-lighting material.

PLED
Polymer light emitting diodes. This is a proprietary technology by CDT. CDT holds the IP for PLEDs. See more here.

PMOLED
Passive Matrix OLEDs. This is probably the simplest form of OLEDs. These are cheap and easy to produce (well, relatively easy, anyway), but a high current is required to maintain the display brightness.

TOLED
TOLED means Transparent OLED. This is a yet another proprietary technology by UDC. Quoting from the web page - The Transparent OLED (TOLED) uses a proprietary transparent contact to create displays that can be made to be top-only emitting, bottom-only emitting, or both top and bottom emitting (transparent). TOLEDs can greatly improve contrast, making it much easier to view displays in bright sunlight. Because TOLEDs are 70% transparent when turned off, they may be integrated into car windshields, architectural windows, and eyewear. Their transparency enables TOLEDs to be used with metal, foils, silicon wafers and other opaque substrates for top-emitting devices.

UDC
Universal Display Corporation (UDC) - an OLED IP company, holding many patents, including flexible and Transparent OLEDs.
