摘要
微透镜阵列用于OLED是改善其输出效率和图像质量的一种有效技术途径。本文将薄膜柱面微透镜阵列用于全彩色OLED平板显示器,研究视角与亮度和色坐标的关系,重点分析了微透镜阵列相对于子像素在不同排列形式下对图像质量指数的影响。研究结果表明,柱面微透镜阵列在提高OLED输出效率的同时,可以明显改善显示器图像的质量,并且,垂直排列时图像质量指数达到了0.8637,优于平行排列时的情况。
Microlens arrays used in OLED is an effective approach which can improve the output efficiency and image quality of the OLED. In this paper, we use cylindrical microlens arrays in OLED display, to research the relation be- tween the viewing angle with luminance and color coordinate, and focuses on the analysis of the image quality that the microlens arrays with different alignments to be applied in sub-pixel. The result proves that cylindrical micro^ens arrays can improve the output efficiency and image quality of the OLED. Besides, the image quality index of the OLED with vertical-aligned cylindrical microlens arrays was improved to 0.8637, which is better than with parallel-aligned cylindri- cal microlens arrays.
