Digitimes Research: Samsung Electronics developing QD technology toward QLED

Jessie Lin, DIGITIMES Research, Taipei 0

Samsung Electronics has launched SUHD (super Ultra HD) TVs, a QD (quantum dot) TV, to compete with OLED TVs launched by LG Electronics, but Samsung Electronics' development of QD display technology is geared toward QLED (quantum dot LED), according to Digitimes Research.

Light emissions based on QD materials is of two modes, photoluminescence and electroluminescence, with the former including types of QDEF (QD enhancement film) LCD, QDCF (QD color filter) LCD, QD-OLED hybrid, RGB (red, green, blue) QD LED and the later mainly being QLED, Digitimes Research indicated.

SUHD TVs are of the QDEF LCD type, and QDCF LCD TVs, with a wide color gamut reaching 98% of Rec. 2020 standards, will be launched in 2017.

Samsung Electronics plans to begin production of QLED TVs in 2019. QLED TVs will have lower production cost and longer service life than OLED models. However, production of QLED TVs currently is faced with technological problems, mainly short service life of blue-color QD materials and how to precisely and evenly coat red, green, blue QD materials.
