Abstract

This study aims to investigate the impact of Bulk Scattering Diffuser (BSD) on color variation in Mini-LED backlight modules under different optical parameters. To predict spectral distribution distortion of BSD in Mini-LED backlight module, a virtual Mini-LED backlight is built in the optical simulation software. The scattering behavior of BSD is also established by the calculation model based on Mie scattering theory. In simulations, the corresponding color coordinate of distorted spectrum is moved in the CIE 1931 color space owing to varying parameters of BSD. Finally, under the condition of highly color uniformity, through the comparison between the color coordinates and the MacAdam ellipse, the suitable manufacturing parameters of BSD are discussed.
