Description

三维液晶显示装置和显示系统及三维图像显示的驱动方法
技术领域
本发明涉及三维显示技术领域，特别是一种三维液晶显示装置、三维液晶显示系统及三维图像显示的驱动方法。
背景技术
随着显示技术的不断发展，人们越来越追求显示内容的现场感，三维技术应运而生。三维技术大体上可分为裸眼三维与戴眼镜三维，由于技术水平和成本等因素的制约，裸眼三维技术并未得到广泛的普及，市场上主要应用的还是需戴眼镜的三维技术，主要有色差式，偏光式和主动快门式。主动快门式三维显示以其良好的显示效果，越来越成为三维市场的主流。Shutter Glass（快门眼镜）越来越成为三维市场的主流，但Crosstalk（串扰）一直是困扰它更好的发挥三维显示效果的瓶颈。
Shutter Glass三维显示是通过提高刷新率的方式，使左右眼要看到的图像数据分时间隔输出，再通过与快门式眼镜的配合，使左眼看左眼的图像，此时右眼眼镜关闭；右眼看右眼的图像，此时左眼眼镜关闭。但由于液晶响应速度不够快，画面反应速度跟不上眼镜的刷新速度，如图1所示的H型图案，左眼看见的图像（3D-L方框）会看到右眼的画面，右眼看见的图像(3D-R方框)会看到了左眼的画面。在三维显示情况下，通过SG眼镜会看到画面出现横向的虚影。
扫描背光可以降低部分Crosstalk,但扫描的区域之间会有扩散。扫描背光的本意是期望通过关闭背光回避液晶的动态响应时间，但相邻背光的串扰会让我们看见我们不想看到的内容。
采用240HZ插黑方法，也可以降低部分Crosstalk,参考刷新率对液晶响应时间有很大要求，在有效的充电时间内，会造成充电率不足。
为了解决以上问题，本发明做了有益改进。
