Description

图像显示装置和这种显示装置的光导体的制造方法
本发明涉及一种图像显示装置，它包括一光调制板，一与该光调制板对着安放的光导体，以及一与该光导体耦连的光源。
本发明还涉及这种显示装置的光导体的一种制造方法。
该光导体可以是一光学元件，也可以具有一空气间隙。
在从美国专利US-A-5,896,232所知的这种图像显示装置中，该光导体包括一些平行延伸的元件，这些元件对于具有第一偏振方向的光是反射的而对于具有第二偏振方向的光却是透明。该图像显示装置特别可用在头戴显示装置(HMD)和投影电视上。透射式或反射式的LCD通常都可用作光的调制板。在反射式LCD中，该LCD从与观察相同一侧进行照明。该光源和相关的光导体都应尽可能薄，以便使该HMD具有相当小巧的形式，特别是对于HMD来说更是如此。这样的好处是，位于光导体的远离该光调制板一侧上的透镜可放置得离该光导体相当近，这对于实现最佳的放大是有利的。
在上述美国专利所描述的图像显示装置中，该光源是位于该光导体的远离该光调制板的一侧。因此，不可能获得相当小巧的结构。此外，该光导体的制造还由于不同的平行延伸的元件而变得相当复杂。
本发明的一目的在于提供一种可避免上述缺陷的图像显示装置。
在按本发明的图像显示装置中，这目的是由于该光导体包括一锯齿状的薄片而实现的，该薄片对于由该光源发出并具有第一偏振方向的光是反射的，而对于经该光调制板调制并具有第二偏振方向的光却是透明的。
例如，该薄片可以是一特别由3M制造，市场名为“DualBrightness Ephancement Film(DBEF)”的反射起偏器。一类似的反射起偏器被介绍于美国专利US-A-5,965,247中。该反射起偏器薄片可以通过两个可相对移动的模件弯折成希望的锯齿形。随后移去该模件或将其与该薄片相连以便形成一光学元件，该锯齿形薄片就位于这光学元件中。
按本发明的图像显示装置的一个实施例，其特征在于：该锯齿形薄片具有一些平行的锯齿形突起，每个突起都包括一个第一面和一个第二面，位于该光源附近并面向该光源的第一面相对于该光调制板的夹角比远离该光源并面向该光源的第一面相对于该光调制板的夹角大。
可以这样来选择该第一面相对于该光调制板的夹角，使得由该光源来的光束以一希望的入射角入射到该薄片上，随后再以一希望的角度射向光调制板，然后又以一希望的角度从该光调制板射出该锯齿形薄片。由于靠近该光源的角度比远离该光源一侧的角度大，因而由该光调制板反射的光束将是发散的。如上所述，一放大光学系统就可设置于该锯齿形薄片的远离该光调制板的一侧，该发散的光束就投射在该放大光学系统上。
本发明的这些和另外一些方面都是明显的，它将借助后面描述的
实施例来进行阐述。
附图如下：
图1表示一按本发明的图像显示装置的实施例，
图2表示一用来制造锯齿形薄片的装置，
图3表示一锯齿形薄片。
这些图中的相应部件都用相同的标号标示。
图1表示一按本发明的图像显示装置1，它包括，例如，一个如反射式LCD之类的光调制板2。该图像显示装置1还包括一与该光调制板2有一间距的锯齿形薄片3。将横向延伸到该光调制板2的漫射板4设置在该光调制板2的两侧。在相对着的两漫射板的远离该光调制板2的一侧至少都各安置有一光源5。该光源5可以是，例如，一发射红，绿或兰光的发光二极管(LED)。
该锯齿形薄片3包括一些突起6，而每个突起都以第一面7和第二面8为界，该第一面与该光调制板2的夹角为α，第二面8与该光调制板2的夹角为β。
该第一面7朝向设置在图1中的光调制板2左侧的光源5，而且靠近该光源5的面7’相对于该光调制板2的角度为α1，在光调制板2的中心附近的面7”相对于该光调制板2的角度为α2，而离该光源5最远的面7”’相对于该光调制板2的角度为α3。随着距离的增加，该角度α也增大，即α3＜α2＜α1。
同样，靠近右侧光源5的面8’相对于该光调制板2的角度为β1，这角度比在光调制板2的中心附近的面8”相对于该光调制板2的角度β2大，依次来看，角度β2又比离右侧光源5最远的面8”’相对于该光调制板2的角度β3大。
该锯齿形薄片3是对称的，也就是，α1＝β1；α2＝β2；α3＝β3。
按本发明的图像显示装置1工作如下。
该薄片3对于来自光源5的光束的偏振方向来说是反射的，而对于来自光调制板2且偏振方向发生变化的光束来说则是透明的。这样来自左侧光源5的光束将被这些面7之一以一给定的角度朝该光调制板2偏转，这取决于该相关的角度α。该光调制板2随后对该光束进行调制并使其偏振方向改变。来自光调制板2的经调制的光束随后就无阻碍地通过该锯齿形薄片3，射向位于与该锯齿形薄片3相对着的光学系统(未画出)。
由于角α1大于角α3和角β1大于β3，所以靠近该光调制板2外侧的反射光束是发散的。
图2表示一种适于用来制造锯齿形薄片3的装置。该装置具有两个模件12、13，其每个都具有一锯齿形的轮廓14，15。该模件12是可朝箭头P1所示方向相对于模件13移动的。在将该模件12移向模件13之前，先将一平的反射起偏器薄片16安放在两模件12，13之间。随后通过按箭头P1所示的方向移动该模件12的方法，将该薄片16在两锯齿形轮廓14和15之间进行弯折，从而形成图3所示的锯齿形薄片3。
图1所示的图像显示装置1可用于HMD、传真阅读器、或移动电话中，也可用于手表、遥控装置、汽车电话中，等等。
另外还可用一DMD来代替反射式LCD作光调制板，其中，在该DMD和光源之间安置有一1/4λ的薄片。
还可使整个锯齿形薄片上具有相等的角度，或使在该锯齿形薄片上的角度发生不同变化。
还可用两种互补的光学元件来制造该模件，其中，通过该光学元件可使该薄片3形变成锯齿状并同时连接在该光学元件上。那时，该光学元件就构成该锯齿形薄片的模具和支持体。
该薄片厚度为，例如，0.13mm。在形成该锯齿形状之后，该锯齿具有的高度为，例如，1mm。该锯齿形薄片3就安置在距该光调制板2的距离为，例如，4-5mm的位置处。
