This chapter establishes the critical link between the human visual system and the performance requirements of electronic displays. The human eye is highly sensitive to luminance, contrast, chromaticity, resolution, and dynamic range, and these parameters directly define the standards for display engineering. Visual perception depends on photoreceptors—cones and rods—that respond to wavelengths in the 400–700 nm visible spectrum, with trichromatic sensitivity enabling color reproduction through red, green, and blue channels. Perceptual thresholds, including spatial resolution (≈ 1 arc minute), response times (~ 0.1 s), and contrast sensitivity, impose strict conditions on how display outputs must be optimized to ensure comfortable, accurate, and fatigue-free viewing.

摘要

This chapter establishes the critical link between the human visual system and the performance requirements of electronic displays. The human eye is highly sensitive to luminance, contrast, chromaticity, resolution, and dynamic range, and these parameters directly define the standards for display engineering. Visual perception depends on photoreceptors—cones and rods—that respond to wavelengths in the 400–700 nm visible spectrum, with trichromatic sensitivity enabling color reproduction through red, green, and blue channels. Perceptual thresholds, including spatial resolution (≈ 1 arc minute), response times (~ 0.1 s), and contrast sensitivity, impose strict conditions on how display outputs must be optimized to ensure comfortable, accurate, and fatigue-free viewing.
