具体实施方式
现在将参考附图更充分地描述各种示范实施方式，在附图中示出了一些示范实施方式。然而，这些发明构思可以以许多不同的形式实施，不应该理解为限于在此阐述的示范实施方式。而是，提供这些示范实施方式使得本公开全面和完整，并向本领域技术人员充分传达发明构思。在附图中，为了清晰可以夸大层和区域的尺寸和相对尺寸。
参照图1，根据本公开的示范实施方式的显示装置1包括在其上显示图像的显示模块10以及容纳显示模块10同时形成显示装置1的外观的壳20。支座30连接到壳20的后表面，使得显示装置1在水平面上以垂直位置站立。
参照图2和图3，显示模块10包括在其上显示图像的显示面板11以及产生光并将产生的光供给到显示面板11的背光12。
显示面板11由具有四边形板形状的液晶面板构成。
背光12包括引导光到显示面板11的导光板121以及产生光的光源122和123。
导光板121由透明材料形成，并提供为相应于显示面板11的四边形板的形状且设置在显示面板11的后面。虽然未示出，但导光板121在相应的部分当中可以提供有允许光从导光板121选择性地发射到显示面板11的图案，使得导光板121通过该图案实现视差屏障功能。
光源122和123包括用于在显示装置1中显示三维图像的三维光源122以及用于在显示装置1中显示二维图像的二维光源123。
三维光源122包括相应的基板122a以及设置在相应的基板122a上的多个相应的发光二极管122b，二维光源123包括基板123a以及设置在基板123a上的多个发光二极管123b。三维光源122的基板122a设置为平行于导光板122的侧端，三维光源122的发光二极管122b设置为面对导光板121的该侧端以朝向导光板121的该侧端辐照光。发光二极管122b在基板122a的纵向上彼此间隔开，如图4所示。根据本公开的示范实施方式，三维光源122的两个单元分别设置在导光板121的两侧，使得光通过导光板121的两个侧端被引入导光板121。
二维光源123的基板123a提供为四边形板的形状，并设置在导光板121的后面以平行于导光板121，发光二极管123b设置在基板123a的前表面上以面对导光板121的后表面从而朝向导光板121的后表面辐照光。
因此，从三维光源122产生的光通过导光板121的两个侧端被引入导光板121，然后发射到提供在导光板121的前面的显示面板11。从二维光源123产生的光通过导光板121的后表面被引入导光板121，然后通过直接穿过导光板121而发射到显示面板11。
如上所述，三维光源122具有在基板122a的纵向上彼此间隔开的多个发光二极管122b，如图4所示。通过光导板121的这样的构造，大量的光被传送到邻近于三维光源122的发光二极管122b的部分，少量的光被传送到远离三维光源122的发光二极管122b的部分，使得会在导光板121的侧端产生亮部分和暗部分。
因此，为了防止在导光板121处产生亮部分和暗部分，背光12包括扩散构件124，每个扩散构件124设置在相应的三维光源122与导光板121的相应的侧端之间。
扩散构件124扩散光并将光传送到导光板121。根据本公开的示范实施方式，扩散构件124由具有白色的半透明材料形成以扩散光。扩散构件124具有四边形条的形状，并提供在其两个单元中且设置在导光板121的横向侧部处从而平行于导光板121的两个侧端。提供在扩散构件124的一侧的第一表面设置为面对三维光源122，扩散构件124的与第一表面相反地设置的第二表面设置为面对导光板121的侧端。三维光源122的基板122a与扩散构件124的第一表面间隔开以平行于第一表面，三维光源122的发光二极管122b也与扩散构件124的第一表面间隔开。
因此，参照图5，从三维光源122产生的光在通过扩散构件的第一表面被引入扩散构件124中并穿过扩散构件124的过程中被扩散，被扩散的光通过扩散构件124的第二表面被发射然后被引入导光板121的侧端。在这种情况下，从发光二极管122b产生的光在穿过扩散构件124的过程中被扩散，使得从扩散构件124的第二表面发射的光在整个第二表面上具有均匀的光分布。因此，具有均匀光分布的光被引入导光板121的侧端，由此防止在导光板121的邻近三维光源122的侧端处产生暗部分和亮部分。
此外，背光12包括反射片125以防止从三维光源122产生的光被泄漏。反射片125提供为覆盖三维光源122与扩散构件124之间形成的空间的外部，使得从光源122产生的光被完全引入扩散构件124。反射片125可以提供为U形以容纳三维光源122和扩散构件124。根据本公开的示范实施方式，反射片125提供在其两个单元中从而相应于三维光源122的两个单元和扩散构件124的两个单元。此外，反射片125延伸以覆盖导光板121的侧端的一部分。
根据本公开的示范实施方式，扩散构件124提供为四边形条的形状，面对三维光源122的第一表面和面对导光板121的侧端的第二表面设置为彼此相反，但是扩散构件124的构造不限于此。参照图6，三维光源122的基板122a可以设置在二维光源123的基板123a的横向侧部处，使得扩散构件124的第一表面和第二表面可以提供为彼此垂直。在这种情况下，扩散构件124可以具有扇形截面而不是四边形截面。
根据本公开的示范实施方式的背光12包括三维光源122和二维光源123，使得显示装置1表示二维屏幕和三维屏幕，但是本公开不限于此。参照图7，扩散构件124和反射片125可以应用于例如通过仅利用面对导光板121的两个侧端的一对光源122而没有利用二维光源123来显示三维图像和二维图像之一的显示装置。
虽然三维光源122包括基板122a和发光二极管122b从而扩散从发光二极管122b产生的光，但本公开不限于此。即使使用除了发光二极管122b之外的不同类型的光源，也可以使用根据本公开的扩散构件124使得被传送到导光板的侧端的光的量被均匀地分布。
此外，根据本公开的示范实施方式的反射片125的两个侧端延伸为覆盖导光板121的侧端的一部分。本公开的这样的结构提供为覆盖可能形成在导光板121的侧端的一部分处的暗部分和亮部分。
由于根据本公开的包括扩散构件124的背光12可以防止在导光板121的侧端处形成暗部分和和亮部分，所以反射片125不必配置为覆盖导光板121的侧端。此外，这样的构造使得光能够通过导光板121的整个前表面发射，从而显示面板11的显示区域可以具有与导光板121相同的尺寸。
此外，虽然根据本公开的示范实施方式的背光12包括相应于导光板121的两个侧端的一对三维光源122和相应于导光板121的两个侧端的一对扩散构件124，但是本公开不限于此。例如，背光12可以包括相应于导光板121的一个侧端的三维光单元122的一个单元以及相应于导光板121的该一个侧端的扩散构件124的一个单元，并可以包括设置在导光板121的另一侧端处的反射构件(未示出)以反射光。
虽然提供在导光板12上的图案允许光从导光板121被选择性地发射到显示面板11，但本公开不限于此。例如，视差屏障或者双凸透镜可以设置在显示面板11与导光板121之间而不必形成图案的构造。
虽然已经示出并描述了一些示范实施方式，但是本领域技术人员将理解，可以对这些示范实施方式进行变化而不背离本发明的原理和精神，本发明的范围由权利要求及其等同物限定。
