Latest Patents
One of his latest patents is for an "Organic light emitting diode display device and method for driving the same." This patent discusses an OLED display device that includes a first transistor, a driving transistor, a first capacitor, a second transistor, an OLED, and a third transistor. The first transistor supplies a data voltage or a reference voltage to a first node according to a scan signal. A gate of the driving transistor is connected to the first node, while its source is connected to a second node, and its drain is connected to a fourth node. The first capacitor is connected between the first and second nodes. The second transistor supplies a high-level source voltage to the second node, allowing the OLED to emit light based on the voltage difference between the first and second nodes. The third transistor connects the fourth node to a fifth node according to a second emission control signal.
Another notable patent is for a "Flexible display substrate, flexible organic light emitting display device and method of manufacturing the same." This invention provides a flexible display substrate that includes a display area and a non-display area extending from the display area. The non-display area is designed in a crooked shape in the bending direction, and the wire positioned on this area includes multiple first wire patterns and a second wire pattern that is electrically connected to the first patterns.
