Dresden Researchers Develop New OLED Structure

Published

on

Researchers at the Technical University of Dresden (TUD) have developed a new OLED structure, which has been supplemented with vertical transparent base transistors (OPBTs). The new structure is called “organic transistor base light emitting transistor” or OPB-LET.

The new design successfully combines the functions of a high efficiency switching element and an organic emitter. OLED transistors (OLET) are three-pole devices in which a thin film transistor is combined with an LED. Unlike previous OLETs, OPB-LET offers high performance thanks to a permeable reference electrode located in the center of the device. The electrode forms a characteristic optical microcavity that controls the injection and transport of charge carriers.

The researchers report that the structure provides high efficiency (up to 24.6% EQE), high brightness (up to 12,513 cd / m2) and low control voltage (less than 5.0 V). This is comparable to the performance of modern OLED devices, but the OPB-LET already has built-in low voltage control transistors.

Not all F 35 fighters show the detected defect All Israeli

All IDF F-35I Adir multirole combat aircraft have been inspected and returned to missions. Flights were suspended after the emergence of information about a possible malfunction of the pilot’s ejection seat.

Concerns about malfunctioning ejection seats arose within the US military. The American side informed all F-35 operators abroad about these concerns, including the Israel Defense Forces Air Force.

Lockheed Martin, which is engaged in production, has published detailed instructions for conducting a technical check. It was recommended to pay special attention to the squib, after which the seat is pushed out of the cab. All Israeli planes were tested, no faults were found.

The Lockheed Martin press service said that the manufacturer is in constant contact with F-35 operators in the US and abroad, in an effort to ensure a high level of safety in the operation of aircraft of this type, and assists in technical inspections.

Earlier it was reported that two of the six F-35 aircraft delivered to the Danish Air Force by the American company Lockheed Martin had malfunctions in the catapult mechanism.
