Description

一种用于液晶屏的全视角3D光栅结构
技术领域
本发明涉及液晶显示技术领域,特别是一种使液晶屏呈现3D显示效果的光栅结构。
背景技术
3D即三维图形,属于虚拟三维技术,3D技术是通过利用计算机的运算达到视觉、听觉等方面立体效果的一种技术。目前市场上实现3D技术的方式有很多种,包括时序法、空间法以及各种3D眼镜技术,为普及3D技术,方便人们观看,还出现了几种3D光栅技术来实现裸眼3D技术,3D光栅技术一般是使用空间分割方法来实现3D技术,使人的左眼和右眼产生相位差,看到不一致的图像,使大脑产生3D图像。
传统的3D光栅结构为在ITO玻璃板上布置若干平行的光栅条,光栅条以斜线方式粘贴在ITO玻璃板上来实现3D效果,通常光栅条的线宽为0.02mm,光栅条的斜度为5°,相邻光栅条之间的间隙宽度为0.5mm,如图1所示。由于受到光栅条结构的限制,传统的3D光栅结构只能在斜线的左右距离不超过45°的视角范围内看到3D效果,上下或者倾斜观看时则3D效果消失,无法实现全视角的3D技术。
发明内容
本发明的目的在于克服现有技术的不足,提供一种能够实现全视角3D技术的光栅结构。
为解决上述技术问题,本发明所采取的技术方案如下。
一种用于液晶屏的全视角3D光栅结构,包括ITO玻璃板以及粘附在ITO玻璃板上的光栅条,所述光栅条以环形方式等间距设置在ITO玻璃板上。
上述用于液晶屏的全视角3D光栅结构,所述光栅条为等螺距的螺旋形环绕结构;螺距为0.3~0.8mm,光栅条的线宽为0.02~0.1mm。
上述用于液晶屏的全视角3D光栅结构,所述光栅条为等间距且同心设置的圆环形结构,每个圆环形光栅条被均匀分割为四个等弧度的圆弧;相邻圆环形光栅条之间的间隙宽度为0.3~0.8mm,光栅条的线宽为0.02~0.1mm。
上述用于液晶屏的全视角3D光栅结构,所述圆环形光栅条的相邻圆弧之间的间隙为0.02-0.1mm。
上述用于液晶屏的全视角3D光栅结构,所述ITO玻璃板为玻璃电阻不大于20Ω的ITO玻璃板。
本发明中实现3D效果的机理是使入射光入射到眼睛时,由光阻挡,使入射到左眼和入射到右眼的光产生相位差,左眼和右眼不同的成像到大脑后形成立体3D效果。所以,在设计光阻挡时,有使光线可以进入左眼和右眼的缝隙,有显示黑条的阻挡块,但传统的设计是直线方式,只能在±45°范围内使人肉眼产生3D效果,一旦突破此视角范围,由于直线阻挡块不会随位置而变化,进入人左眼和右眼的光线就会趋于一致,3D效果消失。本发明为圆形设计,无论从上下左右360°方向看,进入人左眼和右眼的光线阻挡都是一致的,产生的相位差也是一致的,从而使人的眼睛无论从哪个方向看过去,都会呈现稳定一致的全视角的3D立体效果。
附图说明
图1为传统3D光栅的结构示意图;
图2为实施例1的3D光栅结构示意图;
图3为实施例2的3D光栅结构示意图。
图中各标号表示为:1、ITO玻璃板,2、光栅条。
具体实施方式
下面将结合附图和具体实施例对本发明进行进一步详细说明。
本发明包括ITO玻璃板1以及粘附在ITO玻璃板上的光栅条2,光栅条2以环形方式等间距设置在ITO玻璃板上;ITO玻璃板的玻璃电阻不大于20Ω。
实施例1
本实施例中的光栅条为等螺距的螺旋形环绕结构;螺距为0.3~0.8mm,光栅条的线宽为0.02~0.1mm,如图2所示。
实施例2
本实施例中的光栅条为等间距且同心设置的圆环形结构,每个圆环形光栅条被均匀分割为四个等弧度的圆弧,相邻圆弧之间的间隙为0.01mm。ITO玻璃板上相邻圆环形光栅条之间的间隙宽度为0.3~0.8mm,光栅条的线宽为0.02~0.1mm,如图3所示。
本实施例能够使肉眼从各个方向看到一致的空间分割,显示均匀一致,响应速度达10ms,达到了全视角的3D效果。
