Precise theoretical model for quantum-dot color conversion.

Quantum-dot color conversion (QDCC) is a promising technique for next-generation full-color displays, such as QD converted organic light-emitting diodes and micro light-emitting diodes. Although present QDCC research has made some progress on the experimental aspect, the optical model and corresponding mathematical expression that can lay an indispensable foundation for QDCC have not been reported yet. In this paper, we present a theoretical model for precisely describing the complete optical behavior of QDCC, including optical transmission, scattering, absorption, and conversion process.

Edge/direct-lit hybrid mini-LED backlight with U-grooved light guiding plates for local dimming.

Current mini-LED backlights improve high-dynamic-range liquid crystal displays (LCDs) by using tens of thousands of direct-lit sources for local dimming. However, relative thick profile and high power consumption are the inherent limitations while compared with edge-lit backlights. By synthesizing edge- and direct-lit advantages, we propose a novel hybrid mini-LED backlight equipped with a specially designed integrated light guiding plate (LGP) for large-area displays.

Tilted light coupling structure for the thickness reduction of a liquid crystal display backlight.

It is hard to design a traditional edge-lit light guide plate (LGP) as an ultrathin structure, because the LGP thickness will be limited by the luminescence regional width of the LED source. In this paper, a tilted light coupling structure (TLCS) for a liquid crystal display (LCD) backlight is proposed that allows an inclined layout of an edge LED array to significantly reduce the LGP thickness. The design process and optical conditions of the TLCS are first discussed, and the effect of structural parameters on the coupling efficiency is also analyzed.
