Title: Innovations by Bongjun Lee in Display Technology

Introduction

Bongjun Lee is a prominent inventor based in Singapore, known for his significant contributions to display technology. With a total of six patents to his name, he has made remarkable advancements in enhancing the performance of quantum dot—organic light emitting diode (QD-OLED) panels and liquid crystal displays.

Latest Patents

One of Bongjun Lee's latest patents is a low reflection film for QD-OLED panels. This composite film includes a polarizer film, a quarter wavelength retarder film, and a reflective polarizer film. The polarizer film effectively reduces ambient light reflections within the QD-OLED display panel. The quarter wavelength retarder film works in conjunction with the polarizer film to further minimize these reflections, thereby increasing the contrast ratio of the display. Additionally, the reflective polarizer film enhances the luminance of the QD-OLED panel, achieving a brightness level that surpasses that produced by the polarizer and quarter wavelength retarder films alone.

Another notable patent focuses on enhancing color gamut performance in liquid crystal displays. This innovation involves an information handling system that determines an expansion ratio based on the highest grayscale value of a raw image and a maximum grayscale value. The system modifies grayscale values prior to display, adjusting backlight intensity based on a gamma correction curve to optimize pixel transmittance.
