本发明的最佳实施方式
本说明书所使用的词语“实施例”意指用作实例、示例或例证。此外,本说明书和所附权利要求中所使用的冠词“一”一般地可以被解释为意指“一个或多个”,除非另外指定或从上下文可以清楚确定单数形式。
参考图1和图2,图1为本发明的显示装置10的工作方式示意图,图2为本发明的显示装置10的第一实施例的示意图。
本发明的显示装置10包括显示面板102和背光模组,所述显示面板102与所述背光模组叠加组合为一体。
本发明的显示面板102可以是TFT-LCD(Thin Film Transistor Liquid Crystal Display,薄膜晶体管液晶显示面板)、OLED(Organic Light Emitting Diode,有机发光二极管显示面板)等。所述显示面板102包括至少两个像素单元1021,所述显示面板102具有第一表面和第二表面,所述第一表面和所述第二表面为相对设置的两个表面,所述显示面板102用于显示图像20,以及用于透过照射到所述显示面板上的第一光线40和第二光线50。所述第二光线50为从物件30发出或被所述物件30反射的光线。
在本实施例中,所述背光模组是透明或半透明的,即,所述背光模组具有一光线透过率。所述背光模组用于向所述显示面板102提供所述第一光线40,所述背光模组包括光源和光源提供板101。
所述光源用于生成所述第一光线40。所述光源提供板101具有第三表面和第四表面,所述第三表面和所述第四表面为相对设置的两个表面,所述光源设置于所述光源提供板101的一侧,所述光源提供板101用于接收所述光源所生成的所述第一光线40,以及用于向所述显示面板102提供所述第一光线40,所述光源提供板101还用于透过照射到所述第四表面上的所述第二光线50。
所述光源提供板101具有所述光线透过率,所述光线透过率是光线在照射到所述光源提供板101之后透过所述光源提供板101的比率,即,所述光线透过率是光线在照射到所述光源提供板101的所述第三表面之后从所述第二表面出射的比率,所述光线透过率的取值处于10%至99.9%的范围内,例如,所述光线透过率的取值为:11.4%、14.7%、15.3%、17.8%、19.1%、22.8%、24.7%、26.4%、29.3%、32.2%、36.1%、39.5%、42.3%、43.4%、46.8%、48.2%、50.9%、63.8%、66.1%、69.2%、72.1%、75.4%、77.6%、79.7%、82.0%、84.5%、86.1%、88.9%、90.2%、93.3%、95.7%、97.6%、99.9%。
所述显示面板102的所述第二表面与所述光源提供板101的所述第三表面相向设置。具体地,所述第二表面与所述第三表面贴合在一起。
在本实施例中,所述光源提供板101还包括第五表面,所述第五表面为所述光源提供板101的侧面/顶面。
所述光源提供板101包括至少两光线输入接口、至少两个光线提供单元1011以及至少一光线传输通道。
所述光线输入接口用于接收所述光源所产生的所述第一光线40,所述光线输入接口设置于所述第五表面上,所述光线输入接口与所述光源连接。
所述光线提供单元1011在所述光源提供板101上的位置与所述像素单元1021在所述显示面板102上的位置对应,所述光线提供单元1011包括光线输出接口1013。
所述光线输出接口1013用于改变所述光线传输通道所传输的所述第一光线40的传播方向,使得所述第一光线40从所述光线输出接口1013输出后照射所述显示面板102的所述像素单元1021。
所述光线传输通道与所述光线输出接口1013连接,所述光线传输通道用于将所述光源所发出的所述第一光线40传输至所述光线输出接口1013。
在本实施例中,所述光线传输通道为光纤管1012,所述光纤管1012用于传输所述第一光线40。所述光纤管1012具有第一末端和第二末端,所述第一末端位于所述第五表面处,所述第一末端与所述光源连接,所述第二末端与所述光线输出接口1013连接。
在本实施例中,一条所述光纤管1012集中向至少两个所述光线提供单元1011提供所述第一光线40,例如,所述光纤管1012向一列所述光线提供单元1011提供所述第一光线40,其中,所述光纤管1012包括至少两个分段,每一个分段连接于相邻的两个所述光线输出接口1013之间,并且,至少一个所述分段与所述光线输出接口1013和所述光线输入接口连接。也就是说,所述光纤管1012在一个维度上将至少两个所述光线提供单元1011串接起来,以集中向所串接的所述光线提供单元1011提供所述第一光线40。所述光纤管1012设置于所述光线提供单元1011的一侧。
参考图3,图3为图2中的A-A’截面的示意图。
在本实施例中,所述光线输出接口1013包括一斜面,所述斜面表面平整,所述斜面与所述光源提供板101所在的平面具有一夹角,所述斜面用于将所述光纤管1012所传输的所述第一光线40反射至所述像素单元1021中。
在本实施例中,所述光纤管1012设置于所述光线输出接口1013的一侧,所述光纤管1012夹设于所述光线输出接口1013所对应的所述斜面以及所述显示面板102的所述第二表面之间。所述光纤管1012具有一耦接口,所述耦接口与所述光线输出接口1013耦接。所述耦接口可以是平面,也可以是一粗糙面(具有凹凸不平结构的面)。所述耦接口与所述光线输出接口1013的连接处设置有导光胶,所述导光胶为透明的胶体,所述导光胶用于使得所述光纤管1012所提供的所述第一光线从所述耦接口顺利过渡到所述光线输出接口1013,以减少所述第一光线的耗损。此外,所述耦接口与所述光线输出接口1013的连接处还设置有防漏光层,所述防漏光层是一黑色的橡胶层,所述防漏光层涂布于所述导光胶位于所述耦接口与所述光线输出接口1013之间的间隙的外表面。由于所述导光胶为一胶体,因此当所述导光胶设置于所述耦接口与所述光线输出接口1013的连接处后,所述导光胶位于所述间隙处的外表面会形成一光滑的表面,由于所述防漏光层设置于所述导光胶的所述表面上,因此所述导光胶的内表面与所述防漏光层形成一镜面,该镜面用于使得欲出射到导光胶外部的所述第一光线反射会所述导光胶内部(进入到所述光线输出接口1013中),从而可以有效地减少所述第一光线的损耗。
所述斜面的表面可以设置为粗糙状,例如,所述斜面上设置有散射颗粒,所述散射颗粒用于将从所述斜面出射的所述第一光线40打散(发散射出),以使所述第一光线40均匀地照射到与所述斜面所在的所述光线提供单元1011所对应的所述像素单元1021中。所述散射颗粒在所述斜面上的分布可以是不均匀的。所述散射颗粒的形状是不规则的,所述散射颗粒至少具有一个棱角,具体地,所述散射颗粒为形状不规则的多面体,所述散射颗粒是透明或半透明的。所述散射颗粒可以是透明晶体,在这种情况下,所述散射颗粒可以通过粘接的方式设置于所述斜面上,或者,所述散射颗粒与所述光线输出接口1013为同一种材料,此时,所述散射颗粒为所述光线输出接口1013上的突起,所述突起可以在所述斜面上蚀刻出凹陷来形成。
由于所述光纤管1012的一个分段与相邻的两个所述光线输出接口1013连接,所述斜面上的所述散射颗粒有利于使得所述第一光线40从所述光纤管1012的一个分段输入到另一个分段中,也就是说,所述散射颗粒有利于避免用于输入到所述光纤管1012的另一分段的所述第一光线40被所述斜面全部地或过多地反射到相应的所述像素单元1021中,即,有利于避免输入到所述光纤管1012的另一分段的所述第一光线40过少,从而有利于保证每一个所述像素单元1021均能够获取数量大致相等的所述第一光线40。
参考图4,图4为本发明的显示装置的第二实施例的示意图。本实施例与上述第一实施例相似,不同之处在于:
所述光源提供板101的内部设置有阻挡件1014,所述阻挡件1014用于卡设所述光纤管1012,以使所述光纤管1012固定。而所述阻挡件1014将所述光纤管1012固定是为了防止所述光纤管1012移动所造成的所述耦接口与所述光线输出接口1013松动,从而防止所述耦接口与所述光线输出接口1013之间的所述间隙增大,因此避免了漏光,减少了所述第一光线的损耗。
通过上述技术方案,由于用于向所述显示面板102提供所述第一光线40的所述光源提供板101能够透过一定的所述第二光线40,因此观看者能够透过所述显示装置10看到所述显示装置10背后的物件30,在所述显示装置10显示所述图像20时,所述图像20和所述显示装置10背后的所述物件30所对应的景象叠加为一体。
参考图5和图6,图5为本发明的显示装置的第三实施例的示意图,图6为图5中的B-B’截面的示意图。本实施例与上述第一或第二实施例相似,不同之处在于:
所述光纤管1012设置于所述光线提供单元1011的中部。在本实施例中,所述光纤管1012设置于两所述光线输出接口1013之间。
所述光纤管1012设置于两所述光线输出接口1013之间有利于使得所述光纤管1012所提供的所述第一光线能够均匀地遍布所述像素单元1021中,从而提高显示效果。
在上述第一、第二、第三实施例中,所述光线输出接口1013也可以是一曲面,所述曲面用于将所述光纤管1012所传输的所述第一光线40反射至所述像素单元1021中。
具体地,所述曲面为外凸曲面,所述外凸曲面用于将所述光纤管1012所提供的所述第一光线40分散发射到所述像素单元1021的各个区域中。
作为一种改进,所述外凸曲面上可以设置与上述第二实施例类似的所述散射颗粒。
当然,所述曲面也可以是内凹曲面,所述内凹曲面用于将所述光纤管1012所提供的所述第一光线40聚集发射到所述像素单元1021的一个区域,如中间区域。
当然,所述光线输出接口1013也可以是所述斜面与所述曲面的任意组合,例如,所述光线输出接口1013包括所述斜面、所述外凸曲面、所述内凹曲面中的至少两种。
尽管已经相对于一个或多个实现方式示出并描述了本发明,但是本领域技术人员基于对本说明书和附图的阅读和理解将会想到等价变型和修改。本发明包括所有这样的修改和变型,并且仅由所附权利要求的范围限制。特别地关于由上述组件执行的各种功能,用于描述这样的组件的术语旨在对应于执行所述组件的指定功能(例如其在功能上是等价的)的任意组件(除非另外指示),即使在结构上与执行本文所示的本说明书的示范性实现方式中的功能的公开结构不等同。此外,尽管本说明书的特定特征已经相对于若干实现方式中的仅一个被公开,但是这种特征可以与如可以对给定或特定应用而言是期望和有利的其他实现方式的一个或多个其他特征组合。而且,就术语“包括”、“具有”、“含有”或其变形被用在具体实施方式或权利要求中而言,这样的术语旨在以与术语“包含”相似的方式包括。
综上所述,虽然本发明已以优选实施例揭露如上,但上述优选实施例并非用以限制本发明,本领域的普通技术人员,在不脱离本发明的精神和范围内,均可作各种更动与润饰,因此本发明的保护范围以权利要求界定的范围为准。
