Luminance-Preserving Color Conversion

SMPTE Motion Imaging Journal, 2016
With the advent of new television standards introducing ultrahigh definition and high dynamic range, backward compatibility with older devices becomes an issue. We propose a method for converting footage produced in BT.2100 colorimetry to a BT.709 compliant representation.

Color image resolution conversion

IEEE Transactions on Image Processing, 2005
In this paper, we look at the problem of spatially scaling color images. We focus on an approach that takes advantage of the human visual system's color spatial frequency sensitivity. The algorithm performs an efficient least-squares (LS) resolution conversion for the luminance channel and a low-complexity pixel replication/reduction in the chrominance

Dual-Ligand Red Perovskite Ink for Electrohydrodynamic Printing Color Conversion Arrays over 2540 dpi in Near-Eye Micro-LED Display.

Nano letters (Print)
The lack of stability of red perovskite nanocrystals (PeNCs) remains the main problem that restricts their patterning application. In this work, the dual-ligand passivation strategy was introduced to stabilize PeNCs and inhibit their halogen ion ...

Energy Transfer‐Assisted Color Conversion of Persistent Mechanoluminescence in RhB@SiO2/SrAl2O4:Eu,Dy System for Multilevel Information Encryption

Laser & Photonics Reviews
Persistent mechanoluminescence (PML) is highly desirable for its ability to overcome transient‐emitting behavior, but its applications are hindered by the limited emission wavelengths.

Local Light Field Control Enables Efficient Quantum Dot Color Conversion Films for Mini‐LED Backlit Displays

Laser & Photonics Reviews
Quantum dot (QD) color conversion films (QD‐CCFs) are used in ultrahigh definition (UHD) Mini‐LED backlit displays due to their narrow band emission and high color purity.

Organic color‐conversion media for full‐color micro‐LED displays

Journal of the Society for Information Display, 2021
We developed green and red color‐conversion medium (CCM) films for applications in VR/AR microdisplays. These CCM films comprise a host–dopant composition, where the host DMP is a perylene‐based molecule with an absorption coefficient of nearly 2.0 × 105

Color contrast enhanced RGBW conversion

2015 IEEE 4th Global Conference on Consumer Electronics (GCCE), 2015
RGBW display can emit higher intensity level compared to RGB display but one of drawbacks is reduced color saturation. In this paper, we propose RGBW conversion method which considers reduced color saturation problem. Experiment results show that the proposed method is more effective than conventional methods in terms of saturation and intensity ...
