In this study, we proposed an innovative concept of integrating a polarized color-separating backlight with a color-filter-free LC panel for enhancing performance of the curved LCD system. We design a two-level folded backlight to exploit the light sources LEDs with color enhancement by quantum-dot technology to produce color beams emerging at separate angles with a linearly polarizing state. The integrated LC panel focuses the separating color beams onto the corresponding subpixels with no need of the color filter; redirects the color beams at respective angles into the normal and reforms their angular shapes to be identical for attaining good color uniformity in the viewing cone. We established a system model for simulation to evaluate its performance. According to the simulation results, it performs the high optical efficiency of 33.75% that is about four times the traditional LCD, and displays color gamut of 94.1% NTSC (CIE 1931). It also provides the illuminance uniformity of 90% above and good color uniformity in both the spatial space and angular space of the viewing cone with horizontal and vertical angular widths of 100o and 75o, respectively. Furthermore, the simulation results demonstrate that the design can apply to a 55-inch curved LCD and further extend the maximum diagonal size up to 88 inches while keeping slim volume with a minimal thickness of 6.5 mm.

将背光与无滤色器面板集成以提高 LCD 的性能

在这项研究中，我们提出了一个创新的概念，将偏振分色背光与无滤色器的 LC 面板集成在一起，以提高曲面 LCD 系统的性能。我们设计了一种两级折叠背光源，通过量子点技术利用具有颜色增强功能的光源 LED 来产生从不同角度出现的具有线性偏振状态的彩色光束。一体式液晶面板无需彩色滤光片，即可将分离出的色光束聚焦到对应的子像素上；将各个角度的彩色光束重新定向到法线，并将它们的角形状重新调整为相同，以在视锥中获得良好的颜色均匀性。我们建立了一个用于仿真的系统模型来评估其性能。根据仿真结果，它实现了33的高光效率。75% 约为传统 LCD 的四倍，并显示 94.1% NTSC (CIE 1931) 的色域。它还在水平和垂直角宽度分别为100°和75°的视锥的空间空间和角度空间中提供90%以上的照度均匀性和良好的色彩均匀性。此外，仿真结果表明，该设计可应用于 55 英寸曲面 LCD，并进一步将最大对角线尺寸扩展至 88 英寸，同时以 6.5 毫米的最小厚度保持纤薄的体积。
