Title: Innovations of Ming-Chang Shih
Introduction
Ming-Chang Shih is a prominent inventor based in Hsin-Chu, Taiwan. He has made significant contributions to the field of display technology, holding a total of 10 patents. His work focuses on enhancing the performance and efficiency of display devices.
Latest Patents
One of his latest patents is for a display device and driving method thereof. This invention includes a display array and a driving circuit, where the display array features at least one scan line. The driving circuit is responsible for driving the display array and consists of a timing controller and a gate driver. The timing controller manages the refresh rate of the display array at two frequencies, with the first frequency being substantially higher than the second. The gate driver alternates between supplying an enable voltage signal and a disable voltage signal to the scan line. Under the first frequency, a significant voltage difference exists between the enable and disable signals, enhancing the display's performance.
Another notable patent involves compensation circuitry for gate driving pulse signals. This circuitry is designed to receive a gate driving pulse signal and includes several components such as a pre-processing circuit, a peak detector, a discharge circuit, a voltage buffer, and a charge pump circuit. The pre-processing circuit adjusts the voltage of the gate driving pulse signal, which is then analyzed by the peak detector to obtain a peak voltage. The discharge circuit determines whether to enable a discharge loop, while the charge pump circuit modulates the waveform of the gate driving pulse signal based on the peak voltage. This innovation also includes a display device utilizing the compensation circuitry.
