Design and Simulation Analysis of Scattering Netted Dots on Edge-Lighting Flat Light Guide Plate

Based on the analysis of the transmission process of light-beam in edge-lighting flat light-guide plate with Cold Cathode Fluorescent Lamp (CCFL) as a light source, this thesis achieved an arrangement formula and related method to design this kind of light-guide plate with scattering netted dots. According to the method, the designs of flat light-guide plate with scattering netted dots were simulated and analyzed by using ASAP software. Comparing the method with others, it was confirmed that the method was feasible and the good uniform luminance distribution on the flat light-guide plate for LCD was obtained by using this method. Key words: light-guide plate, scattering netted dots, the function of netted dots filling ratios
