20170269274 · 2017-09-21 ·

The present invention provides a method for manufacturing a quantum dot polarization plate. The method for manufacturing a quantum dot polarization plate according to the present invention forms a quantum dot layer and a polarization layer separately on different bases to respectively make a quantum dot film and a polarization film and then bonds the quantum dot film and the polarization film together to form a quantum dot polarization plate. The quantum dot polarization plate is not made through successive formations of films on the same base so that the quantum dot layer of the quantum dot polarization plate can be manufactured through a high-temperature process or a low-temperature process, thereby expanding the range of material section and manufacture for quantum dots. The quantum dot polarization plate manufactured with such process helps increase color gamut coverage of the display panel, but does not cause elimination of light polarization.
