Summary
This summary is machine-generated.Wide Color Gamut Displays (WCGDs) can oversaturate colors due to their expanded gamut and Electro-Optical Transfer Function (EOTF). This study analyzes the issue and proposes two optimization strategies for accurate color reproduction.
Area Of Science
- Display technology
- Color science
- Image processing
Background
- Display color performance is determined by gamut and Electro-Optical Transfer Function (EOTF).
- Wide Color Gamut Displays (WCGDs) offer enhanced color but can exhibit oversaturation.
- Standardized image sources contrast with terminals pursuing wider gamuts.
Purpose Of The Study
- Analyze the color oversaturation problem in WCGDs.
- Develop strategies to optimize WCGD color performance.

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.
The absorption of UV–visible light by conjugated systems causes the promotion of an electron from the ground state to the excited state. Consequently, photochemical electrocyclic reactions proceed via the excited-state HOMO rather than the ground-state HOMO. Since the ground- and excited-state HOMOs have different symmetries, the stereochemical outcome of electrocyclic reactions depends on the mode of activation; i.e., thermal or photochemical.
