Problems solved by technology

However, in general, a higher haze value achieves greater diffusion of external light, which improves the anti-glare effect, but also causes image distortion due to surface scattering of light and whitening phenomenon due to internal scattering of light, thus deteriorating contrast
In this way, an increase in image clarity and contrast deteriorates anti-glare characteristics, and an increase in anti-glare characteristics causes image clarity and contrast to deteriorate
