We fabricated surface pattern on a light guide panel (LGP) using CO2 laser to improve the luminescence performance of inner-scatterer LGP, which is made of PMMA sample with exploiting Q-switched 2nd harmonic Nd:YAG laser engraving system, and the effect of surface pattern in the brightness distribution of LGP was analysed. To prove the feasibility of proposed method in the enhancement of LGP performance, we designed three different surface patterns on the innerscatterer LGP. The experimental results has proved the potential in the application of surface pattern to increasing the brightness of inner-scatterer LGP.
