Latest Patents
One of Chen's latest patents is titled "Pixel circuit for active matrix OLED and driving method." This invention proposes a pixel circuit that includes five transistors and one capacitance. The design allows a first transistor to connect to a control line, enabling a second transistor to disconnect from the scan line when a low voltage is applied. This innovative approach helps to avoid large current generation and IR-drop, resulting in more uniform illumination compared to prior art.
Another notable patent is the "Active matrix LED pixel driving circuit." This circuit features a capacitor, a light-emitting diode, and two transistors. The capacitor is positioned between the gate and source of the first transistor. The second transistor's source is connected to the drain of the first transistor, with its gate receiving a first voltage. This configuration allows for efficient operation in a saturation region, where a first current corresponding to a data signal flows through both transistors to generate a second voltage stored on the capacitor. When the current switch is opened, the second current activates the light-emitting diode, showcasing Chen's innovative approach to driving LED pixels.
