Description

触摸屏一体型反射型LCD装置及电子装置
技术领域
本发明涉及一种作为移动体通信终端装置、信息设备、便携式个人计算机等各种电子设备的显示装置而被采用的反射型LCD装置(液晶显示装置)、以及具备该反射型LCD装置的电子装置。
背景技术
近年来的电子装置多采用具有带触摸屏的前导光板结构的反射型LCD装置。图2是表示现有的触摸屏一体型反射型LCD装置的构成的分解斜视图。该装置的主要构成要素包括：触摸屏21、间隔体22、上薄膜23、底板24(玻璃或塑料制)、ITO电路25(位于上(上表面侧)薄膜23和底(底面侧)板24之间)、反射体26、棱镜棒27、LED28、导光板29、反射型LCD30(反射型液晶显示体)。
但是，在这样的现有的触摸屏一体型反射型LCD装置的结构中，导光板29和触摸屏21被组装成留有间隔相互分开。所以，作为基本模块结构的导光板29和触摸屏21，即使分别制作后组装在一起，形成一个单独的外壳，对于现有的触摸屏一体型反射型LCD装置的结构来说，也会增加装置的厚度和重量，如果进行变薄变轻的设计则会发生故障而产生问题，至今这一问题也没有得到解决。
在具备现有的触摸屏一体型反射型LCD装置的制品中，导光板29与触摸屏21之间存在空隙(空气层)，当在触摸屏上书写文字或施加压力时，会对导光板表面上的凹凸槽起到减少损伤的保护作用。但是，因为存在该空隙(空气层)增加了整个装置的厚度，这并不能算是好的结构。
本发明鉴于上述现有装置的问题点而提出来的，其目的在于对现有存在多余空隙的LCD屏的结构进行改良，提供具有结构上薄化、轻化、反射性能提高、制造成本削减等高质量性能的新型触摸屏一体型反射型LCD装置，以及具备该触摸屏一体型反射型LCD装置的电子装置。
发明内容
为了解决上述课题，本发明的触摸屏一体型反射型LCD装置及电子装置使用以下手段。并且，以下所付符号与表示反射型LCD装置的本发明附图1是一致的。
(1)触摸屏一体型反射型LCD装置，具备具有电极的透光性触摸屏体A、表面具有反射用凹凸x的前导光体C、及反射型LCD体D，并按照触摸屏体A、前导光体C、反射型LCD体D的顺序形成叠层结构而一体构成，其中，在上述触摸屏体A与上述前导光体C之间，设有覆盖前导光体C的光反射用凹凸x的涂层B，来形成叠层结构。
(2)该触摸屏一体型反射型LCD装置，其中，上述涂层B与上述触摸屏体A之间不设空隙，来形成叠层结构。
(3)这些触摸屏一体型反射型LCD装置，其中，构成上述涂层B的材料与上述前导光体C的折射率不同。
(4)这些触摸屏一体型反射型LCD装置，其中，上述涂层B作为紫外线保护层而形成。
(5)具有画面显示装置的电子装置，其中，上述画面显示装置应用权利要求1至4中任何一项所述的触摸屏一体型反射型LCD装置构成。
附图说明
图1是表示本发明触摸屏一体型反射型LCD装置的剖面结构的一例的说明图。
图2是表示现有的触摸屏一体型反射型LCD装置的构成的分解斜视图。
具体实施方式
以下，参照附图来详细说明本发明的触摸屏一体型反射型LCD装置及电子装置的实施方式。
图1是表示本发明触摸屏一体型反射型LCD装置的剖面结构的一例的说明图。参照此图来说明本发明触摸屏一体型反射型LCD装置的主要构成要素。首先，触摸屏体A按照透光薄膜1、上层电极2、下层电极3的顺序由叠层层叠构成。
涂层(coating layer)B(4)优选由触摸屏体A及前导光体C不设空隙地形成叠层结构。另外，构成该涂层B的材料也可以与前导光体C的折射率不同。再有，该涂层B作为紫外线保护膜的UV(Ultraviolet)涂层形成，也是有效的。
前导光体C(5)，其表面具有用于反射光的很多反射用凹凸槽x，该表面涂抹了UV涂层，以便通过涂层B层状地覆盖整个表面，使得表面众多的反射用凹凸槽能够得到保护。
本发明的触摸屏一体型反射型LCD装置中，光源8被反射体9(反射板)反射，然后，经由棱镜棒7再被前导光体C(5)反射，然后，光源8在反射型LCD体D中再被反射，穿过触摸屏体A向外部射出。
产业上的利用可能性
如果采用本发明，则可发挥以下的优良的效果。也就是说，在本发明相关的触摸屏一体型反射型LCD装置中，通过缩小现有装置结构上的多余空隙来形成涂层，产生该装置结构上薄化、轻化、反射性能提高、制造成本降低等多种优点，并可很容易的应用于各种电子装置。另外，本发明通过采用涂层，不仅使触摸屏一体型反射型LCD装置在结构上没有多余的空隙而形成坚固的一体结构，而且可实现亮度、光度的均一性以及很好的透光性。
