|February 23, 2018
Summary
This study introduces a wide color gamut display using white and emerald backlights. Adjusting the light mixing ratio maximizes color reproduction, proving effective in experiments.
Area of Science:
- Display Technology
- Color Science
- Optical Engineering
Background:
- Liquid crystal displays (LCDs) traditionally face limitations in achieving wide color gamut.
- Enhancing color reproduction is crucial for applications like digital imaging and visual media.
Purpose of the Study:
- To propose and validate a novel wide color gamut approach for LCDs.
- To determine the optimal mixing ratio of white and emerald backlights for maximal color gamut coverage.
Main Methods:
- Implementing a backlight system with controllable white and emerald lighting units.
- Analyzing the color gamut coverage ratio based on varying mixing ratios of the two light sources.
- Conducting experimental validation of the proposed method.
Main Results:
- The proposed white and emerald backlight system effectively expands the color gamut of the LCD.
- A specific mixing ratio was identified to achieve maximal color gamut coverage.
- Experimental results confirmed the efficacy of the approach.
Conclusions:
- The integration of white and emerald backlights offers a viable solution for wide color gamut displays.
- Controlling the mixing ratio of these backlights is key to optimizing color performance.
- This technique presents a significant advancement in display color technology.

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

1.5K
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

01:14Changes in Skin Color: Clinical Perspectives
3.8K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

15.8K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.

01:39Epistasis
50.3K
In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...
