液晶显示器（LCD）现在是用于消费者电视应用的流行显示技术。我们以前的研究表明，传统的LCD计算机显示器不太适合时间顺序的立体可视化，由于扫描图像更新方法，液晶显示器的保持型操作，在某些情况下，缓慢的像素响应速率。最近，一些新技术被用于液晶电视，以改善2D运动再现-如黑帧插入和100/120赫兹的能力。本文报道了对最近的液晶电视的测试，以调查其与时序立体显示方法的兼容性-特别是调查新的显示技术。在这项调查中考虑的方面包括图像更新方法，像素响应速率，最大输入帧速率，背光操作，帧速率上转换技术，同步等，一个更先进的Matlab程序也开发了作为本研究的一部分，以模拟和表征3D兼容性和计算串扰存在于每个显示器。该项目的结果表明，黑框插入确实提高了LCD的3D兼容性，但没有达到足够的水平来产生良好的3D效果。不幸的是，与之前测试的LCD显示器相比，测试LCD的100/120 Hz操作并没有改善3D兼容性。
Liquid Crystal Displays (LCD) are now a popular display technology for consumer television applications. Our previous research has shown that conventional LCD computer monitors are not well suited to time-sequential stereoscopic visualization due to the scanning image update method, the hold-type operation of LCDs, and in some cases slow pixel response rate. Recently some new technologies are being used in LCD TVs to improve 2D motion reproduction - such as black frame insertion and 100/120Hz capability. This paper reports on the testing of a selection of recent LCD TVs to investigate their compatibility with the time-sequential stereoscopic display method - particularly investigating new display technologies. Aspects considered in this investigation include image update method, pixel response rate, maximum input frame rate, backlight operation, frame rate up-conversion technique, synchronization, etc. A more advanced Matlab program was also developed as part of this study to simulate and characterize 3D compatibility and calculate the crosstalk present on each display. The results of the project show that black frame insertion does improve 3D compatibility of LCDs but not to a sufficient level to produce good 3D results. Unfortunately 100/120Hz operation of the tested LCD did not improve 3D compatibility compared to the LCD monitors tested previously.
