Description

光学膜的堆叠方法、该方法形成的膜包和含膜包的显示系统
发明领域
本发明涉及光学显示器，具体地涉及光学显示器中所用控光光学膜的封装方法。
发明背景
光学显示器，如液晶显示器(LCD)越来越普遍地用于例如移动电话、从个人数字助理(PDA)到电子游戏机甚至到更大的装置如膝上计算机的手持式电脑设备、LCD监视器和电视荧屏。在光学显示器装置中引入控光膜可改进显示器性能。不同类型的膜，包括具有棱柱结构的膜、反射偏振器和漫射膜可用来改善显示参数，如输出亮度、照明均匀性、视角和整个系统效率。这样改进了操作特征后，装置更容易使用，有可能提高电池寿命。
控光膜通常一个个堆到背光灯组合件和平面显示板之间的显示框里。可优化膜堆，得到所需的特定光学性能。但从生产角度看，在搬运和组装若干一个个膜片上存在一些问题。这些问题包括从单个光学膜上清除保护衬垫需要过多的时间，清除衬垫时损坏膜的可能性又增大，等等。此外，将许多一个个膜片插入显示框很费时间，将它们堆积起来又有可能破坏膜。所有这些问题减小了总体生产能力，或者说降低了产率，导致系统成本增加。
发明概述
考虑到上述问题，本发明的目标是一种新型封装方法，它将若干光学膜结合在一起，然后再插入显示框。这种结合方法使膜搬运起来更容易，减少了组装显示装置所需的步骤，降低了膜受损的几率，增加了产率。
本发明总体上涉及两个或多个控光膜的堆的封装，其中至少两块膜是无隙结合在一起的。
本发明的一种实施方式涉及用来将光控制在显示器内的控光膜包。此膜包包含有一堆至少第一和第二光学膜，它们分别具有第一和第二视域，排列起来形成一个堆视域。在第一和第二光学膜之间有是无隙结合的，无隙结合部位位于第一和第二视域的外面。

本发明的另一种实施方式涉及控光膜包，用来将光控制在显示器内。该膜包包含具有第一表面的第一光学膜和位于第一光学膜之上的第二光学膜。第二光学膜具有无隙结合到第一光学膜第一表面上的第一表面。第二光学膜的中央可视部分没有结合到第一光学膜上。
本发明的另一种实施方式涉及一种显示系统，它含有照明单元、显示单元和位于照明单元与显示单元之间的控光单元，控光单元可以控制光从照明单元到达显示单元。控光单元包含一堆至少第一和第二光学膜，第一光学膜具有第一表面，第二光学膜位于第一光学膜之上。第二光学膜具有用无隙膜结合体结合到第一光学膜第一表面上的第一表面。第二光学膜的中央可视部分没有结合到第一光学膜上。
本发明的另一种实施方式涉及控光膜包，用来将光控制在显示器内。该膜包包含具有第一表面的第一光学膜和位于第一光学膜之上的第二光学膜。第二光学膜具有第一表面，它被将第一和第二光学膜结合到一起的无隙膜结合体结合到第一光学膜第一表面上。第二光学膜的中央可视部分没有结合到第一光学膜上。

本发明可应用于显示器，如液晶显示器，特别适用来减少制造这种显示器所需的步骤。
图1所示为显示系统100的示意图。该系统包含电子显示元件102，如液晶显示(LCD)板，通常夹在两个玻璃层之间。此外，显示元件102可在LCD板上下包含吸收起偏层，提供产生偏振图像通常所需的偏振对比。
背光灯组合件104可用作显示元件102的主光源，或者当环境光不够使用者观看显示元件102形成的图像时，用来提供通过显示元件102的光。在一种特定的实施方式中，背光灯组合件104可包含若干元件，如光源106、光导108和一个或多个反光层110。在许多应用中，显示系统100的一个重要特点是系统100的总厚度较小。相应地，光源106通常安置在光导108的侧面，光导108使来自光源106的光向上穿过系统100，射向显示元件。光源106可以是任何适当类型的光源。在许多应用中，需要用白光照射显示器100，此时光源106可以是荧光灯、发光二极管阵列等，所述发光二极管的颜色混和起来产生白光。
在所示实施方式中，光导108含有漫反射区域112，这些区域将光从光导108导向显示元件102。光导108可包含其他类型的元件，用以将光投向显示元件102，如光导108朝向显示元件的上表面上的聚光区。聚光特征结构也可同时在光导108的上下表面上提供。不难理解，光导108可以是图示那样的平板形式，也可以是另一种几何形式，例如楔形。另外，也可用其他器件将来自光源的光投向显示元件102。
也可采用背光灯组合件的其他实施方式，例如，背光灯组合件可由位于适当反射腔中的一排灯组成。虽然背光灯组合件有其他若干可供选择的结构形式，但应当理解，背光灯组合件的具体结构形式对本发明并不重要。
在背光灯组合件104和显示元件102之间的控光膜堆114中通常安置了若干控光膜。控光膜堆114通常包含若干个膜，用以控制入射到显示元件102上的光的各种光学特性。例如，控光膜堆可包含第一漫射膜116。第一漫射膜可用来帮助均化通过膜堆114的光的强度。
膜118和120可以是结构膜，它们的上表面上可以有一排棱柱状肋119。棱柱状肋有助于将光投向系统100的光轴130。膜118的肋119将光再投向平行于图面的方向。膜120上的肋通常不平行于膜118。膜120的肋可垂直于膜118上的肋119，这样膜120上的肋就将光再导向垂直于图面的方向。这可称作交叉结构。在另一种实施方式中(未示出)，层118和120可用单结构光学膜取代，它对从背光灯组合件104的接受光进行再导向。
堆114也可包含反射起偏层122。此层用来回射来自背光灯组合件104但偏振态不对，不能作为图像光通过显示元件102的光。反射起偏层122反射的光可由反射层110漫反射，使偏振态发生一些混和，这样至少一部分反射光可以以正确的偏振态通过显示元件102，用作图像光。此外，可用偏振转换层，例如1/4波长延迟层将反射起偏层122反射的光的偏振态进行转换。反射起偏层122可以是任何合适类型的反射起偏层，例如多聚合物层膜、胆甾型起偏层或线栅起偏层。
堆114也可包含另一种漫射片124，通常称作“覆盖片”。漫射片124通常是较弱的漫反射体。漫射片116和124可用来使显示元件102受到的照明对于观看者来说显得均匀。应当指出，根据系统的实际结构，层116-124所表示的某些元件可以省略，也可以加上其他功能元件或为它们所取代。
对于这种膜堆114，每个独立的光学膜层116-124都必须在生产过程中一个一个地插入显示框。由于要减少显示器的总体厚度，减少膜116-124的厚度往往很重要，所以各个膜116-124要做得很薄。结果，各个膜的刚度可能很低，导致生产过程中的搬运、加工和组装困难。同样，因为这些膜层往往具有精密的光学功能，所以表面缺陷的产生，如刮痕或碎屑可能影响系统的总体性能。常常在每个膜层的两面加上保护衬垫，在插入背光灯组合件之前又必须将保护衬垫除去。除去衬垫的动作和后来将膜插入背光灯组合件的动作都可能给精密的膜带来许多引起缺陷的危险。这种缺陷的例子包括刮伤、由于静电而吸附在膜表面上的棉绒和其他碎屑。此外，清除衬垫需要额外的操作步骤，所以减少需要清除的衬垫的数量就是减少了操作步骤，从而节省了生产成本。在背光灯组合件中插入多个膜层时，产生/引入缺陷的可能会更大，这会因过多的重复工作和更高的单位成本而降低生产能力。
本发明涉及结合许多光学膜层和/或组件的方法，为的是提高搬运和最终的背光/系统的组装效率。
结合多个光学层的一种方法包括在每两块相邻的膜之间插入胶粘剂层。胶粘剂层可从边缘到边缘铺满整个膜堆，可以沿着膜堆的一条或多条边缘施加，也可按一定图案施加在有些或全部膜层的部分区域。
这种胶粘剂粘合方式可完成多块膜的结合，但每个胶粘剂层增加了厚度，通常约25μm或以上。这样就会使膜堆的总体厚度增加较大，不利于最终的结构，特别是对于空间受限的应用是不利的，因为此时膜堆的厚度应尽可能小。此外，在结构表面上添加胶粘剂层可能使结构表面的折射性质受到显著的影响，甚至可能使总体折射性质消失。这就可能影响具有结构折射表面的膜，如棱柱形膜118和120的光导效应。却是需要构建这样一种封装光学膜堆，其中将膜层结合到一起的方法可保持任何膜结构的所需折射性质，特别是在空间受限的应用中，堆厚增加甚少或者没有增加。
形成本发明结合膜堆200的一种方法表示于图2a中。层216-224表示显示系统的控光膜堆中可能存在的不同光学层。例如，层216可以是漫反射层，层218和220可以是导光结构膜，层220的取向与层218交叉。层222可以是反射起偏层，而层224可以是漫反射层。
结合230表示将相邻膜层固定在一起的结合体。结合体230可以是不连续的结合的，即允许膜层的未结合部分存在气隙，例如在一块包含结构上的膜的表面。这种气隙可用来保持特定光学膜，如结构光学膜218和220的有效功能，将光再导向膜堆214的轴232。结合体230在膜层216-224表面上可以以直线或几何图形的形式处在一个点或几个点上。也可以较好将结合体230安置在部分或全部层216-224的边缘小凸片上。这些小片也可作为将结合的膜堆200固定到显示框上的定位元件。
图2B是棱柱形结构膜266与另一块膜270之间的结合体230的放大图。在此实施方式中，棱柱形结构膜266周边的平台部位268可用来形成结合体230。膜266和270之间的气隙272允许棱柱形结构膜使光再次通过，而不会增加膜堆的厚度。
可用不同方法减少或防止堆膜光学质量的下降。例如，谨慎操作，减少膜间污染微粒，从而防止形成牛顿环。此外，相互接触的一个或两个表面可以存在微小的高度差，以防止润湿，如美国专利6322236所讨论的，该文献参考结合于此。同样，棱柱形结构膜可具有高度有差异的结构表面，如美国专利5771328所述，该文献参考结合于此。
可以采用不同类型的结合体，在每个结合体部位都不会明显增加膜堆的厚度。在结合体的部位，结合在一起的膜层之间没有间隙。膜层彼此直接结合，因而这种结合体可称作无隙结合体，或者直接结合体。结合体230可以是热焊，例如通过超声焊接、激光焊接等形成的热焊。结合元件230也可以是溶剂焊。例如，光学控光膜可由丙烯酸酯类，如聚甲基丙烯酸甲酯，或聚碳酸酯形成。这种膜可用二氯甲烷作溶剂进行溶剂焊接。另一种类型的直接结合体是褶皱，此时结合在一起的层形成褶皱，防止一层相对于另一层移动。
结合的膜堆300的顶视图示于图3，只显示了最顶部的膜302。堆中的各个膜具有一个或多个边缘小凸片304。小凸片304可具有许多不同的形状、数目和位置，具体取决于最终背光灯/系统组件的具体结构。小凸片304可提供区域，在组装或检查过程中方便地将堆300固定，也可在将堆固定在显示器上时对膜堆进行定位。所图示实施方式中，环形无隙结合体306位于小凸片304的区域。在环形焊情况下，中央开口308可用来将销插入背光灯组合件用于定位，并用来固定光学膜堆300。无隙结合体306也可具有不同形状，例如环形或线形。
在膜中，光通过并到达显示元件和观看者的部分称作视域。最顶部的膜302的视域简示为虚线310所围住的区域。为了减小膜包的尺寸，视域宜占据膜尽可能多的面积。在某些情况下，视域可延伸到接近膜的边缘。此外，在视域保持较高的光学质量很重要。由于用来形成无隙结合体的许多结合技术会改变膜的光学质量，在许多情况下将无隙结合体置于视域外面就比较重要。因此，举例来说，无隙结合体可形成在膜本身的边缘312上，或者在位于视域外面的小凸片304上。
将膜上的小凸片结合到一起的一个优点是，当膜用溶剂焊接结合起来时，可减少溶剂在膜间通过虹吸作用流走的可能性。
显示器400的放大图示于图4，它显示了将显示器的不同部分组装成显示器的情况。显示器400用框402容纳其他组件。框402可包含一条或多条狭缝404，或其他对齐特征，例如插销等，用来对齐控光膜堆中的膜。
背光灯组合件406是第一个放入框402中的组件。背光灯组合件406包含一个或多个光源408，它们照射光导410的边缘。然后将控光膜堆412放置在背光灯组合件406上面。控光膜堆412包含两块或多块控光膜414，它们用无隙结合体416结合在一起。在图示的实施方式中，结合体416位于对齐小凸片418上，这些小凸片将膜堆412与对齐狭缝404对齐。包含起偏层的显示元件420，例如液晶显示元件，放置在控光膜堆412上面。
应当理解，光源408与显示元件具有电结合，用来接受电力和控制信号。电结合没有示出。
相互结合的控光膜堆也可直接结合到一个显示元件上。这种显示器的一个例子示意于图5。在此特定实施方式中，结合的膜堆514由相互结合的一些膜516-524形成。在图示实施方式中，膜518和520是棱柱形结构膜。膜516可以是漫射膜，也可以是光转向膜，例如棱柱形结构膜，其棱柱形结构表面朝向背光灯组合件504。
显示器也包含显示元件502和背光灯组合件504，背光灯组合件包含光源506、光导508和下面的反射体510。结合的光学膜堆514可事先用前面提到的方法结合在一起，然后锚定到所选择的显示元件上。在另一种方法中，结合过程可在最后安装到所选显示元件上的时候进行。
在图示实施方式中，结合的膜堆514可通过例如在膜516和光导508边缘涂胶粘剂的方法粘附到背光灯组合件504上。在另一种实施方式中，光学膜堆514可锚定在显示元件502或框上(未示出)。此方法可能比较有利，因为它能自动进行，从而避免了用手工插光学膜堆的操作。这样可最大程度减少缺陷的产生，同时提高生产能力，降低单位成本。
在一些实施方式中，下位的膜516可延伸到堆514的右边缘外面，膜516的外延部分可用作固定光源506的底座。
控制器，例如处理器等，通常连接到显示元件502上，用来控制观看者所看到的图像。
在平板显示器这样的装置中采用结合的膜堆具有若干好处。显示器中使用的许多控光膜非常薄。例如，每块棱柱结构膜可具有约62μm的厚度，而反射起偏层的厚度可在约1-100μm之间。显示器中所用控光膜往往柔性很强，在组装显示器的过程中可能引起问题。另一方面，结合多个又薄又有柔性的膜可能产生较硬一些的膜堆，这会使组装容易一些。在组装显示器时，省去依次堆叠一个个层的过程也使产生缺陷和最终产率损失的可能性最小。此外，由于膜通常在两面有保护衬垫的情况下由生产厂家运送到显示器组装线，若减少膜结合在一起时显示器组装线必须清除的保护衬垫的数量，就进一步优化了产率和生产单位成本。
此外，相对于分别检查一个个膜层，将光学膜结合在一起后可在最后进行整体检查，并能提高检查质量。当采用结构光学膜时，这一点很容易想到，因为结构光学膜容易变形，且在底层或其他膜层中藏匿缺陷，如果一个个单独检测这些层，则这些缺陷容易检查到。最后，结合形式，如超声焊或其他结合技术，可提供无隙结合功能和其他机械安装灵活性。
应当理解，除了无隙结合体的至少两块膜外，膜堆还可包含在其他膜之间的无隙结合体。例如，无隙结合体可以是位于两块膜之间的胶粘剂。
光学膜往往是制成大面积的，在某些情况下卷成膜卷。要组装在显示器中的一个个膜可从大的膜上切下，通常用模切方式。可以若干不同的方式用无隙结合体这些膜结合到结合堆中。例如，可将膜模切成合适的形状，然后放置在堆中结合起来。在其他方式中，膜可以一边模切一边结合，甚至可以在模切之前就结合。此外，可以一次结合两块或多块膜。因此，应当理解，包含三块或多块膜的堆可分两个或多个结合步骤形成。例如，头两块膜可结合在一起，形成结合的堆，然后在一个或多个结合步骤中将一块或多块膜结合到这个堆上。
形成无隙结合堆的总方法示意于图6。两片光学膜602和604进入结合设备606，在膜602和604之间形成无隙结合体，产生无隙结合膜堆。有若干方法可在这两膜之间形成无隙结合体。一种途径是采用热结合，此时结合体是将一层或两层加热到层材料软化甚至熔化的温度下形成。在加热过程中或加热之后也可加压。热可以不同方式施加。一种途径是通过辐射传热加热，一个例子是激光结合，此时一个或两个层吸收激光，形成热。另一种途径是通过传导传热加热，例如采用热压。也可以通过对流的形式加热，例如通过喷嘴向结合部位通入热气。加热的另一种途径是摩擦生热。这种能量转移的一个例子是超声焊接。
形成无隙结合体的其他方法包括化学和机械方法。化学方法的一个例子是采用溶剂，将溶剂放在层间要形成结合体的地方。机械方法的例子包括使两层形成褶皱。各层也可用回形针别在一起，或者将它们固定在一个框中，框环绕部分或全部膜堆。
现在按图7介绍将至少两块膜结合在一起的一个特定例子。在此特定实施方式中，使用一个旋转超声焊。匹配和结合膜的过程可以是连续的。
第一膜辊702包含至少一面有衬垫的一卷膜。衬垫704由剥离辊706剥去。第二膜辊708也可包含至少一面有衬垫的一卷膜。衬垫710由第二剥离辊712剥去。剥离去衬垫后的膜714和716通过两个辊720和722。这个辊对后面是一个超声焊接单元724。在此特定实施方式中，超声焊接单元724包含静止不动的超声发生器726和转动砧728。砧728通常包含与膜714接触的凸片部分，将彼此相对的膜714和716压向超声发生器726。结果是，结合的一对膜730从超声焊接单元724出来后，在其长度方向具有重复的焊接图案。膜714和716的外表面可能仍然含有衬垫，所以结合的膜对730在外表面上具有保护衬垫。
然后可让结合的膜730对通过一对切割辊732，这对辊有一个旋转模734和一个旋转砧736。旋转模734与模对730上的焊按图案配合，用来将膜对730切成膜堆738。在另一种特定实施方式中，旋转模734可吻切结合的膜对730到一控制深度，一直切到下膜的下衬垫。然后可剥去外围不需要的部分740，在下衬垫层742上留下一排膜堆。然后可用收集辊744将下衬垫层742收集起来。
应当理解，这只是形成无隙结合体的许多不同方法中的一种。
两块膜714和716可以是任何控光膜。例如，第一膜714可以是棱柱形结构膜，在膜714上有横向的肋，而第二膜716是棱柱形结构膜，膜716上有横向的肋。第一和第二膜714和716也可以是其他类型的控光膜，如漫射膜或反射起偏膜。
在结合堆叠的膜的另一种方法中，不同的膜可以彼此成直角的方向送入。例如，两个膜辊上可以是棱柱形结构膜，每块膜具有横肋状结构。在这种情况下，来自两个辊的膜可以直角彼此交叉，因而堆叠的棱柱形膜也交叉。可用单焊在它们重叠的地方焊接起来，并用切割工具切割。
如上所述，本发明可应用于显示器，可以认为特别适保用来减少制造这种显示器所需的步骤。不应当认为本发明受限于上述特定实施方式，而应当理解为覆盖所权利要求所完整确定的本发明所有方面。在本领域的技术人员看过本发明的说明书后，适用于本发明的各种改进形式、等价过程和许多结构是显而易见的。权利要求意在覆盖这些改进形式和装置。
