摘要： The present invention relates to the field of color filters, in particular, to a non-absorbing polarization color filters and to high-brightness color liquid crystal display panel with improved image contrast employing non-absorbing polarization color filters and light recycling among neighboring subpixels. The disclosed invention represents a non-absorbing polarization color filter comprising the following elements: a rear broadband multilayer lossless polarizer, a front broadband multilayer lossless polarizer, and a color polarization rotator. The rear broadband multilayer lossless polarizer has a predefined-oriented transmission axis AB. Said front broadband multilayer lossless polarizer is located approximately in parallel with the rear broadband multilayer lossless polarizer, and has a transmission axis approximately parallel or approximately orthogonal with respect to transmission axis AB. The color polarization rotator is located between the front broadband multilayer lossless polarizer and the rear broadband multilayer lossless polarizer. Said color polarization rotator comprises a stack of thin birefringent films with c-axes orientations alternated in sign according to a rocking angle α with respect to orientation of the transmission axis AB. A number, a rocking angle α, thicknesses and optical anisotropies of thin birefringent films are selected so, that the non-absorbing polarization color filter transmits a predetermined color light having the polarization state approximately parallel to transmission axis AB, reflects said predetermined color light having the polarization state orthogonal to the transmission axis AB, and reflects an unpolarized light of other predetermined color.

摘要： The present invention provides a liquid crystal display apparatus and a method for viewing liquid crystal displays over a wide range of viewing angles with minimal loss in image contrast and gray level. Prior art liquid crystal displays (LCDs) exhibit low contrast and gray level inversion when viewed at large viewing angles. Prior art solutions to these problems include using a phase retardation plate or film interposed between the liquid crystal layer and a polarizer layer as an optical compensator. While such a solution improves image contrast and reduces some undesirable angular effects, the fabrication of such phase retardation compensator films requires precise thickness control and is expensive. The present invention discloses that by tilting the absorption axis of the birefringent polymer molecules comprising the polarizer sheet to orient at an appropriate angle relative to the liquid crystal image display panel, the contrast ratios and the gray level stability are substantially improved for wide angle viewing. For projection displays, absorption axis tilting (tilting) can be done by simply tilting the plane of a standard polarizer sheet relative to the plane of the LC image display. For flat panel displays, tilting can be accomplished by using a new type of sheet polarizer in which the long axis of the parallel chains of polymer molecules within the sheet are tilted relative to the physical plane occupied by the polarizer sheet and the adjacent coplanar liquid crystal layer.
摘要翻译：本发明提供了一种液晶显示装置和用于在宽范围的视角上观看液晶显示器的方法，其中图像对比度和灰度级的损失最小。现有技术的液晶显示器（LCD）在大视角观看时表现出低对比度和灰度级反转。对于这些问题的现有技术方案包括使用介于液晶层和偏振器层之间的相位延迟板或膜作为光学补偿器。虽然这样的解决方案提高了图像对比度并减少了一些不期望的角度效应，但是这种相位延迟补偿膜的制造需要精确的厚度控制并且是昂贵的。本发明公开了通过使包含偏振片的双折射聚合物分子的吸收轴相对于液晶图像显示面板以适当的角度倾斜，对于广角观察，对比度和灰度稳定性显着提高。对于投影显示，吸收轴倾斜（倾斜）可以通过简单地倾斜标准偏振片的平面相对于LC图像显示的平面来进行。对于平板显示器，倾斜可以通过使用新型薄片偏振器来实现，其中片材内的聚合物分子的平行链的长轴相对于偏振片所占据的物理平面和相邻的共面液晶层。
