Laser-induced scatterer patterns in a light guide panel(LGP) have provided partially concentrated light distribution, especially near the light entrance of the LGP. Additional treatments for enhancing performance of the LGP, such as gradually increased processing depth, were also developed, but minor improvement was observed in the fabricated LGP. To solve this problem, we designed a revised scatterer pattern to be inscribed into the LGP using different laser processing depths and different
