In this paper, we have developed a scheme to make small size QD (quantum dot) display come true. We will show the structure and principle of QD display in this paper. It is different from QD enhancement film which is used in backlight, our work focus on developing QD color filter. Compared with traditional LCD, the brightness and color purity of QD‐LCD have been greatly improved. In our development projects, the QD Color filter is realized through the lithography process and we got wide color gamut up to 99.2%BT2020 (equal to 132.86%NTSC) in Cd based QD, and 93.6%BT2020 (equal to 125.35%NTSC) in Cd‐free QD. In this paper we focused on the explaining architectural principles used during design and implementation.
