Development of functional diffusion sheet for liquid crystal display using new laser microprocessing technology

采用本实验室研制的新型激光微加工技术，制作了液晶显示器用扩散座。与传统的生产工艺相比，采用纳秒脉冲紫外激光的工艺简单。通过使用这种技术，我们能够在聚对苯二甲酸乙二醇酯（PET）和聚苯硫醚（PPS）的透明树脂片上制造可重复的小孔。具有窄间距通孔的树脂片作为液晶显示的扩散座。

The diffusion seat for liquid crystal display was made by using new laser microprocessing technology which was developed by our laboratory. This technique using nanosecond pulse UV laser is simple compared with the conventional production technology. By using this technique, we were able to make reproducible small holes in transparent resin sheets of polyethylene terephtalate (PET) and polyphenylene sulfide (PPS). The resin sheets having through holes with narrow pitch function as the diffusion seat for liquid crystal display.
