摘要
利用TracePro仿真软件对狭缝光栅自由立体LED显示器件的串扰进行仿真。首先, 通过对狭缝光栅的设计原理分析, 并基于LED模块的发光像素面积2 mm×2 mm, 黑矩阵的面积1 mm×1 mm, 设定最佳观看距离为5 m的两视点狭缝光栅自由立体LED显示器件, 计算出光栅的狭缝宽度和挡光宽度都为2.87 mm。其次, 利用这些参数, 通过TracePro软件建立狭缝光栅自由立体LED显示器件的仿真模型, 通过仿真运算得到左、右视频的光照度分布图, 并通过归一化发现它们的光照度均匀性较差, 观看时会导致“眩晕”现象。最后, 借助自由立体显示器件串扰的测量方法, 根据仿真左、右视频照度分布图的交叉曲线, 定性分析了仿真结果, 并结合Orign 9.1软件定量对仿真的串扰值进行计算, 得出其串扰值为42.4%。这为进一步优化狭缝光栅自由立体LED显示器件的设计和性能提供了理论依据和技术支持。
Abstract
In this article, an optical software of TracePro was used to simulate the crosstalk of LED autostereoscopic display. Based on analyzing the design theory of two viewing-point LED autostereoscopic display, the LED model lighting pixel area is 2 mm×2 mm, and the black matrix area is 1 mm×1 mm. Assuming that the best view distance is 5 m, we calculate the silt and barrier width are both 2.87 mm. With these parameters, we can model the crosstalk of LED autostereoscopic display to compute and qualitatively analyze the illuminance of left and right view. With normalizing the illuminance, we found different uniformity distribution will cause dizzy phenomenon. Finally, according to the measurement method of crosstalk and the crosstalk of left and right simulation illuminance, we also get the crosstalk value of the LED autostereoscopic display, which is 42.4% obtained by Origin 9.1 software. This supplies the theory and technology method to improve the design and performance of LED autostereoscopic display.
