At present, the diffuser plate is an important optical diffusion part inside the TV set, which can distribute the light emitted by the LED in the TV set uniformly. It can make the light of LED in the TV set evenly distributed. In this paper, transmittance (T.T.), fog degrees (HAZE) and brightness (Lv) three aspects were studied, the main and auxiliary materials including GPPS, organic silicon light diffusion agent, inorganic optical diffusion agent and anti-aging agent were analyzed, and several kinds of organic and inorganic optical diffusion agents were compared and analyzed. The results showed that when the organic silicon light diffusion agent dosage was 0.6%~0.8%, the inorganic optical diffusion agent was 0.15%, the transmittance reached (43±3) %, the fog degree was up to 99.4%.
