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 notable patent is for a display apparatus and pixel driving method with a current compensation function. This display device includes pixels, a data line, a first current compensation unit, a second current compensation unit, and a control unit. The first current compensation unit is configured to provide a first current to pixels through the data line, compensating for a leakage current that flows out of the data line. The second current compensation unit is designed to sink a second current from pixels through the data line, compensating for the leakage current that flows into the data line. The control unit manages the first and second current compensation units based on the voltage of the data line.
