The relevant parameters were designed by the volume scattering light guide plate (LGP) simulation software. According to the values of the relevant parameters
the volume scattering LGP samples were prepared. The view angle and the distribution of the output light were measured and analyzed. The results show that the output light mainly distributes in deviation from the normal of LGP at certain angle direction and a good uniformity of intensity can be achieved. In addition
the measured results are close to the simulated results.
