Title: Innovations of Yueh-Ping Chang

Introduction

Yueh-Ping Chang is a notable inventor based in Miaoli, Taiwan. He has made significant contributions to the field of liquid crystal display technology. With a total of 5 patents, his work has advanced the capabilities of display devices.

Latest Patents

Chang's latest patents include a vertical alignment liquid crystal display device that features transistors with varying switch-on resistance. This innovative device comprises a display panel with multiple pixels. Each pixel unit consists of a first thin film transistor (TFT), a second TFT, and a liquid crystal capacitor that includes a pixel electrode and a common electrode. The common electrode is supplied with a common voltage, while a first gray voltage is applied to the pixel electrode through the first TFT. Additionally, a second gray voltage is applied through the second TFT, which differs from the first gray voltage. This design allows the liquid crystal capacitor to maintain two distinct gray voltages during the display frame time of the vertical alignment liquid crystal display.

Another patent by Chang focuses on a vertical alignment liquid crystal display device and the method for driving it. Similar to his previous patent, this device also includes a display panel with multiple pixels and utilizes the same TFT and liquid crystal capacitor configuration. The innovative approach ensures that the liquid crystal capacitor can sustain two different gray voltages effectively.
