Diffuser technology is a vital differentiator in the optical performance of LCDs. The authors outline some common approaches for backlighting and film stacks and explain how different types of diffuser films are employed. They also describe how micro‐lens diffusers in LCD backlight modules can provide performance that is 10% better than that of bead‐filled coated PET diffusers and equivalent to that of coated micro‐lens PET diffusers.
