Here, we report multilayer stacking of films of quantum dots (QDs) for the purpose of tailoring the energy band alignment between charge transport layers and light emitting layers of different color in quantum dot light-emitting diodes (QD LED) for maximum efficiency in full color operation. The performance of QD LEDs formed by transfer printing compares favorably to that of conventional device...
Colour prediction models (CPM) can be used to analyze the printing quality of halftone-based color printing systems. In this paper, we consider the Neugebauer CPM which requires as input the fraction of occupation of each primary. To obtain these numbers, we apply several image segmentation algorithms, with and without contextual information. These segmentation algorithms are evaluated with res...
The problem of stabilizing a single color tone reproduction curve of a xerographic printing engine is considered. This problem is critical to ensure high-fidelity color printing. The control system uses a small number of actuators and a small number of measurements to stabilize the potentially high-dimensional tone reproduction curve. The goal is to minimize the overall least squares deviation ...
A computer simulation was performed to investigate the optimum combinations of threeand four-chromatic inks in order to maximize the color gamut for halftone printing. A virtual printing model was created based on the YuleNielsen-spectral-Neugebauer equations and Kubelka-Munk turbid media theory and was used to predict the spectral reflectances and colorimetric coordinates of prints. In this ma...
ISO/TC130 is responsible for international printing standards development. Normative requirements for process control have been centered on solid coloration and TVI. Grey balance and grey reproduction are being addressed in the revision of ISO/WD1 12647-2 (2011). In this regard, the ISO/WD1 12647-2 (2011) takes paper color into consideration when defining grey reproduction aims, but there is a ...
The color inconstancy of prints is related to the ink spectral properties and the lookup table for multiink printing systems. In this paper, color inconstancy was investigated for several ink-jet printers based on their ink set and the default lookup tables. A virtual model for each printer was created to determine the range of color inconstancy that a specific ink set could achieve. The color ...
Augmented reality (AR) and virtual (VR) are two novel display technologies that under updates. The essential feature of AR/VR is the full-color requires high pixel densities. To generate three-color pixels, fluorescent color conversion layer inevitably includes green red pixels. fabricate such sort kits, inkjet printing a promising way to position layers. In this review article, progress first ...
