← ScienceWhich mechanism impairs LCD contrast when pressure is applied?
A)Stress-induced birefringence misalignment✓
B)Increased quantum dot emission
C)Reduced backlight LED intensity
D)Fresnel reflection amplification
💡 Explanation
Applied pressure misaligns liquid crystal molecules, impacting polarization; stress-induced birefringence occurs because the refractive index becomes anisotropic. Therefore, contrast degrades due to the altering of polarization, rather than altered emission or reflection rates.
