Quantum Dot LCD Display

Quantum Dot LCD Display is an emerging technology in displays. It based on QD backlighting system. It is the QD polymer film or QD coating that converts blue light from conventional LED into pure green and red colors. Then RGB lights go to the LCD matrix and produce a display image. Such QD backlight system brings a wide color gamut, more bright and contrast images. Also it decreases energy consumption significantly. Nowadays, many TV makers adopted this technology, such as Sony, Samsung and others.

QD Backlight System Fabrication

QD backlight system can be fabricated as follows. Colloidal Quantum Dots are mixed with polymer solution. The polymer can be PMMA, polyurethane, etc. Then Quantum Dot polymer film is prepared on a suitable substrate. The final Quantum Dot film is used with blue or UV LED to make a backlighting system.
