Title: Chang-Gyu Lee: Innovator in Flat Panel Display Technology

Introduction

Chang-Gyu Lee is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of display technology, particularly in the development of flat panel displays. With a total of seven patents to his name, Lee's work has had a substantial impact on the industry.

Latest Patents

One of Lee's latest patents focuses on a flat panel display with improved white balance. This invention enhances the white balance by adjusting the doping concentration or the shape and size of drain offset regions of driving transistors in the red (R), green (G), and blue (B) unit pixels of each pixel. The flat panel display comprises multiple pixels, each containing R, G, and B unit pixels to represent the respective colors. Each unit pixel includes a transistor with source and drain regions. Notably, transistors of at least two unit pixels have drain regions with different geometric structures. The design ensures that the resistance value of the drain region of the transistor driving the light-emitting device with the highest luminous efficiency is greater than that of the transistor driving the device with relatively lower luminous efficiency.

Another patent by Lee also addresses the improvement of white balance in flat panel displays. This invention utilizes offset lengths or doping concentrations of offset regions between multi-gates of driving transistors in R, G, and B unit pixels. Similar to his previous patent, this flat panel display consists of multiple pixels, each containing R, G, and B unit pixels. The transistors in these unit pixels have offset regions with varying geometric structures. The offset region of the transistor driving the light-emitting device with the highest luminous efficiency is designed to have a longer offset length or a lower doping concentration compared to those of transistors driving devices with lower luminous efficiency.
