Light-modulated quantum dot color display and method for manufacturing the same

Abstract

A light-modulated quantum dot (QD) color display according to an embodiment of the present disclosure includes a light source, a light modulator positioned above the light source to control the intensity of light generated from the light source, and a QD light-emitting element positioned above the light modulator and including a plurality of QD patterns having different emission properties in the visible light region by means of light intensity that has passed through the light modulator. According to an embodiment, the QD pattern is configured to accomplish light emission with uniformity and high color purity by uniform distribution of QDs in a matrix using aligned polymer, thereby simultaneously achieving the features of uniform emission of light over the entire pixel, intensity-tunability giving analog grey levels, and high color purity and wide color gamut without using a color filter beyond the limitation of existing QD color display technology.
