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101和背光模组102,所述显示面板101与所述背光模组102叠加组合为一体。
本发明的显示面板101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101包括至少两个像素单元1011,所述显示面板101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101用于显示图像20,以及用于透过照射到所述第二表面上的第一光线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102是透明或半透明的,即,所述背光模组102具有一光线透过率。所述背光模组102用于向所述显示面板101提供所述第一光线40,所述背光模组102包括光源和光源提供板。
所述光源用于生成所述第一光线40。所述光源提供板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的一侧,所述光源提供板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101提供所述第一光线40,所述光源提供板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之后透过所述光源提供板的比率,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101的所述第二表面与所述光源提供板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,所述光源提供板还包括第五表面,所述第五表面为所述光源提供板的侧面。
所述光线提供板包括至少两光线输入接口、至少两个光线提供单元1021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1021在所述光源提供板上的位置与所述像素单元1011在所述显示面板101上的位置对应,所述光线提供单元1021包括光线输出接口。
所述光线输出接口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输出后照射所述显示面板101的所述像素单元1011。
所述光线传输通道与所述光线输出接口连接,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。
在本实施例中,所述光线传输通道为光纤管10211,所述光纤管10211用于传输所述第一光线40。所述光纤管10211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连接。
在本实施例中,所述光线输出接口包括一斜面10212,所述斜面10212表面平整,所述斜面10212与所述光线提供板所在的平面具有一夹角,所述斜面10212用于将所述光纤管10211所传输的所述第一光线40反射至所述像素单元1011中。
在本实施例中,所述光纤管10211可以设置为扁平状,也就是说,所述光纤管10211的横截面为矩形或者与矩形相近的形状,所述横截面的长边平行于所述像素单元1011所在的平面,所述横截面的短边垂直于所述像素单元1011所在的平面。
参考图3,图3为图2中的背光模组102的光源提供板的第一实施例的示意图。
在本实施例中,一条所述光纤管10211集中向至少两个所述光线提供单元1021提供所述第一光线40,例如,所述光纤管10211向一列所述光线提供单元1021提供所述第一光线40,其中,所述光纤管10211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之间,并且,至少一个所述分段与所述光线输出接口和所述光线输入接口连接。
参考图4,图4为图2中的背光模组102的光源提供板的第二实施例的示意图。
当然,每一个所述光纤管10211也可以单独向一个所述光线提供单元1021输出所述第一光线40,其中,每一所述光纤管10211连接所述光线输出接口和所述光纤输入接口。
通过上述技术方案,由于用于向所述显示面板101提供所述第一光线40的所述光源提供板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,图5为本发明的显示装置10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:
所述斜面10212的表面设置为粗糙状,例如,所述斜面10212上设置有散射颗粒10213,所述散射颗粒10213用于将从所述斜面10212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10212所在的所述光线提供单元1021所对应的所述像素单元1011中。所述散射颗粒10213在所述斜面10212上的分布可以是不均匀的。所述散射颗粒10213的形状是不规则的,所述散射颗粒10213至少具有一个棱角,具体地,所述散射颗粒10213为形状不规则的多面体,所述散射颗粒10213是透明或半透明的。所述散射颗粒10213可以是透明晶体,在这种情况下,所述散射颗粒10213可以通过粘接的方式设置于所述斜面10212上,或者,所述散射颗粒10213与所述光线输出接口为同一种材料,此时,所述散射颗粒10213为所述光线输出接口上的突起,所述突起可以在所述斜面10212上蚀刻出凹陷来形成。
此外,在所述光纤管10211集中向至少两个所述光线提供单元1021提供所述第一光线40的情况下,所述光纤管10211的一个分段与相邻的两个所述光线输出接口连接,所述斜面10212上的所述散射颗粒10213有利于使得所述第一光线40从所述光纤管10211的一个分段输入到另一个分段中,也就是说,所述散射颗粒10213有利于避免用于输入到所述光纤管10211的另一分段的所述第一光线40被所述斜面10212全部地或过多地反射到相应的所述像素单元1011中,即,有利于避免输入到所述光纤管10211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1011均能够获取数量大致相等的所述第一光线40。
参考图6,图6为本发明的显示装置10的第三实施例的示意图。本实施例与上述第一实施例或第二实施例相似,不同之处在于:
所述光线输出接口为一曲面,所述曲面用于将所述光纤管10211所传输的所述第一光线40反射至所述像素单元1011中。
具体地,所述曲面为外凸曲面10214,所述外凸曲面10214用于将所述光纤管10211所提供的所述第一光线40分散发射到所述像素单元1011的各个区域中。
作为一种改进,所述外凸曲面10214上可以设置与上述第二实施例类似的所述散射颗粒10213。
图7为本发明的显示装置10的第四实施例的示意图。本实施例与上述第三实施例相似,不同之处在于:
所述曲面为内凹曲面10215,所述内凹曲面10215用于将所述光纤管10211所提供的所述第一光线40聚集发射到所述像素单元1011的一个区域,如中间区域。
本发明的显示装置10的第四实施例与上述第一至第四实施例中的任意一个实施例相似,不同之处在于:
所述光线输出接口为所述斜面10212与所述曲面的任意组合,例如,所述光线输出接口包括所述斜面10212、所述外凸曲面10214、所述内凹曲面10215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。
