Latest Patents

Cheng's latest patent is a method of preventing the cathode of an active matrix organic light emitting diode from breaking. This innovative method involves providing a substrate with an array of thin film transistors. Each thin film transistor consists of a gate electrode, a channel layer, a source terminal, and a drain terminal. A passivation layer is formed over the substrate, which is then planarized. An opening that exposes the drain terminal is created in the passivation layer. An anode layer is formed over the passivation layer and the interior of a portion of the opening, ensuring that the drain terminal and the anode layer are electrically connected. Finally, a light-emitting layer and a cathode layer are sequentially formed over the substrate to create an active matrix organic light emitting device.
