ORGANIC LIGHT-EMITTING DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17860399 titled 'ORGANIC LIGHT-EMITTING DEVICE

Simplified Explanation

The patent application describes an organic light-emitting device (OLED) with specific compounds in the intermediate layer between the two electrodes. These compounds have silyl group-containing groups, carbazole-derived groups, and triazine groups. The energy level of at least one of the compounds is 2.81 eV or higher.

• The OLED includes a first electrode, a second electrode, and an intermediate layer.
• The intermediate layer consists of two compounds: a first compound and a second compound.
• The first compound has a silyl group-containing group and at least two carbazole-derived groups.
• One carbazole-derived group is bonded to another carbazole-derived group through a nitrogen atom.
• The second compound has a silyl group-containing group, a triazine group, and a carbazole-derived group.
• At least one of the compounds has a triplet energy level of 2.81 eV or more.

Potential applications of this technology:

• OLED displays for electronic devices such as smartphones, tablets, and televisions.
• Lighting panels for energy-efficient and flexible lighting solutions.
• Wearable displays for smartwatches, fitness trackers, and augmented reality glasses.

Problems solved by this technology:

• Improved efficiency and performance of OLED devices.
• Enhanced stability and lifespan of OLED displays.
• Compatibility with various electronic devices and applications.

Benefits of this technology:

• Higher energy efficiency leading to reduced power consumption.
• Brighter and more vibrant colors in OLED displays.
• Longer lifespan and improved durability of OLED devices.
• Compatibility with a wide range of electronic devices and applications.

Original Abstract Submitted

An organic light-emitting device including: a first electrode and a second electrode each having a surface opposite the other; and an intermediate layer disposed between the first electrode and the second electrode, the intermediate layer including a first compound and a second compound, wherein the first compound includes a first silyl group-containing group and at least two carbazole-derived groups, wherein one carbazole-derived group of the at least two carbazole-derived groups is bonded via a N atom to another carbazole-derived group, the second compound includes a second silyl group-containing group, a triazine group, and a carbazole-derived group, and at least one of the first compound or the second compound has a triplet (T) energy level of 2.81 eV or more.
