Title: Lun-Ming Chang and Gate-Driver Protection Innovation.
Introduction
Lun-Ming Chang is an inventor associated with Taipei, Taiwan. His listed patent work concerns a protection circuit designed for gate drivers in liquid crystal displays.
Latest Patents
Chang is credited with 1 patent: “Start Protection Circuit for Gate Driver and Liquid Crystal Display Thereof.” The invention uses a detection circuit to monitor the gate low voltage and generate a control signal. It first outputs the gate low voltage and checks whether it has reached a predetermined level. Once that level is reached, the detection circuit activates a switch to transmit the gate high voltage. This sequence is intended to provide start-up protection for the gate driver.
Career Highlights
Chang is associated with Chunghwa Picture Tubes, Ltd. His listed invention addresses a specific display-system challenge by coordinating gate-voltage output during start-up.
Collaborations
Chang’s listed coworkers include Chao-Yong Hsu and Ching-Hui Ku.
Conclusion
Lun-Ming Chang’s patent reflects a focused contribution to liquid crystal display technology, using controlled voltage sequencing to protect a gate driver during start-up.
