摘要

柱镜光栅式自由3D显示器的串扰问题和分辨率下降问题是影响其广泛应用的主要因素。采用定向背光方案,通过设计一种蝶形单元液晶显示屏光开关面板实现自由3D显示器的无串扰和无分辨率损失。详细推导了定向背光柱镜光栅面板的参数计算公式,给出了55 in(1 in=2.54 cm)4K 3D电视屏的定向背光模块结构参数,并采用TracePro软件仿真优化了设计参数。仿真结果表明,设计的自由3D显示器最低串扰小于0.01%,近似无串扰,并且与现有眼镜快门开关式3D视频图像完全兼容,图像无分辨率损失。

Abstract

The applicability of lenticular-lens-based autostereoscopic 3D display is limited due to its crosstalk and degradation of resolution. Autostereoscopic display with no crosstalk and full resolution is realized by designing a butterfly-shaped liquid crystal display shutter in a multi-directional backlight unit. And the calculation formulas of parameters of the directional backlight lenticular panel are derived theoretically. Furthermore, the multi-directional backlight unit parameters of a 55 in (1 in=2.54 cm) 4K model autostereoscopic 3D displayer are presented, and they are optimized by TracePro software. The simulation results show that the crosstalk of designed autostereoscopic display is less than 0.01% which can be approximate to zero, and it can be fully compatible with the existing glasses shutter switch 3D video images with no loss of resolution.
