Title: Innovations of Liang-Hua Yeh in Liquid Crystal Technology.

Introduction

Liang-Hua Yeh is a prominent inventor based in Taipei, Taiwan. He has made significant contributions to the field of liquid crystal technology, holding a total of 10 patents. His work focuses on enhancing the performance and efficiency of liquid crystal panels, which are essential components in various display technologies.

Latest Patents

One of Liang-Hua Yeh's latest patents is a timing controller for liquid crystal panels. This invention provides a timing control method that includes a timing control unit for analyzing input signals to generate a system state transition voltage (STV) signal and a base STV signal. The timing control unit outputs a base trigger signal and a switch trigger signal with asynchronous frame rates to a select unit simultaneously. A compare unit determines whether the frequencies of the two state signals are the same, allowing the select unit to decide which signal to forward to a level shift circuit. Ultimately, a signal-time control unit manages the output time of both the base trigger signal and the switch trigger signal, ensuring that each liquid crystal unit connected to the gate line has an equal charge time.
