Title: Innovations of Chun-Hao Tung in Flat Panel Display Technology

Introduction

Chun-Hao Tung is a prominent inventor based in Hsinchu, Taiwan, known for his significant contributions to the field of flat panel display technology. With a total of 13 patents to his name, Tung has developed innovative methods that enhance the manufacturing processes of display devices.

Latest Patents

One of his latest patents is a method for manufacturing an array substrate for flat panel display devices. This method utilizes photolithography with four masks to produce a TFT-LCD. By employing this technique, the manufacturing of thin-film transistors (TFTs) and the definition of the pixel area can be completed after the third half-tone mask is used. This approach effectively avoids alignment deviations and the generation of parasitic capacitance that often occurs with conventional photolithography methods that use five masks. As a result, this innovation reduces costs and increases yield. Another notable patent involves the fabrication of an LCD TFT array plate using a lift-off method and half-tone photolithography. This process requires only two photo masks to define the first and second metal layers, streamlining the production of the LCD TFT array plate.

Career Highlights

Chun-Hao Tung has worked with several notable companies in the display technology sector, including AU Optronics Corporation and Quanta Display Inc. His experience in these organizations has allowed him to refine his skills and contribute to advancements in display technology.
