Latest Patents

One of his latest patents is a shift register that comprises a first switch, a second switch, a third switch, and a fourth switch. The first switch selectively conducts a first clock signal to a first output terminal as a first output signal based on a voltage level over the control terminal. The second switch selectively forces a voltage level of the first output signal to be equal to a voltage level of a second clock signal based on both the second clock signal and a third clock signal inverted to the second clock signal. The third switch selectively defines a voltage over the control terminal to be a first voltage based on a first input signal. The fourth switch selectively forces the voltage level over the control terminal to be equal to the voltage level of the second clock signal based on both the second clock signal and the third clock signal.

Another significant patent is related to a pixel circuit and display device using the same. This pixel circuit includes four transistors, two capacitors, and a light-emitting element. A gate of the first transistor receives a scan signal, and a source/drain thereof receives display data. A terminal of the first capacitor couples to another source/drain of the first transistor. A gate and a source/drain of the second transistor couple to another terminal of the first capacitor, while another source/drain thereof receives a switch signal. A terminal of the second capacitor receives a reset signal, and another terminal thereof couples to another terminal of the first capacitor. A gate of the third transistor couples to a terminal of the first capacitor. A gate of the fourth transistor receives an enable signal, with a source/drain thereof coupling to a first power supply voltage, and another source/drain thereof coupling to one source/drain of the third transistor. The anode and cathode of the light-emitting element couple to one source/drain of the third transistor and a second power supply voltage, respectively.
