Past, present, and future of WCG technology in display

Abstract

We will introduce the development trend of colorant and color technology along the grown of display industry. Wide color gamut (WCG) technology with high contrast ratio and transmittance has been developed from colorant design to color filter process, product reliability, and performance enhancement. In this paper, WCG technology for liquid crystal display (LCD) and organic light emitting diode (OLED) and trend of colorant, which is including color conversion material (CCM), were discussed. We hope that it will help you to understand the development flow of colorant in the display industry.
