摘　　要：针对镭射型导光板网点设计需求,提出了采用区域分割法及斥力缓和法来实现网点的合理分布.设计了一种网点密度分布物理模型,利用该模型控制导光板网点按照LED的光学特点分布.镭射型导光板网点的设计难以控制半径和深度按图案规律变化,只能是通过调节其网点密度来实现网点分布合理化,通过区域分割法生成网点并且使用斥力缓和法对网点进行微调,最后得到了高均匀性的无规则网点分布,将调整前的网点分布和调整后的网点分布进行对比得出斥力缓和法是一种调整网点间距的有效方法.针对区域分割方法生成网点容易出现区域边界过渡带的问题,使用重新中分法,使得区域边界的过渡带问题得到了有效的解决,这对于控制背光模组的光学效果具有重要的意义.Based on laser marking condition, two approaches named repulsive relaxation and area division for dot patterns designing for light guide plate are proposed in this paper. Laser marking method is not applicable to dot patterns with different radius, for laser power can＇t vary with radius of dot patterns. Boundaries between different areas are significantly smoother after redivideing viewing area. By using repulsive relaxation and area division methods, dot patterns with high uniformity and sufficient irregularity, which are significant for improving the optical effect of backlight module were derived.
