Latest Patents

Choong's latest inventions reflect his expertise and innovation in organic electroluminescent devices. His patents include:

1. **Organic Electroluminescent Device with Improved Reliability**: This organic EL device features a layered structure consisting of a cathode, an organic electroluminescent layer, and an anode. The organic layer is designed with a continuous medium made of components A, B, and C, which are essential for transporting electrons and holes. Specifically, A's content varies from 0% to 100% depending on proximity to the cathode, while B’s content inversely correlates. Component C incorporates a hole-injecting agent like a porphyrinic compound (e.g., CuPc or MgPc), enhancing the device's performance.

2. **Organic Electroluminescent Device with Continuous Organic Medium**: This patent also involves a cathode, organic electroluminescent layer, and an anode, but focuses on an organic layer comprised of a medium formed by components A and B. Here, A is responsible for electron transport, while B facilitates hole transport. The incorporation of Rubrene or its derivatives in the organic layer significantly boosts luminescence efficiency.
