具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例的附图，对本发明实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1所示，图1为本发明实施例提供的显示装置的第一种部分结构示意图。本发明实施例提供一种显示装置，包括：透明导光板1和位于透明导光板1侧面的光源3，光源3向透明导光板1背离其出光面12的一面倾斜设置。即，光源3朝向透明导光板1背离其出光面12的一面，光源3与竖直平面之间具有夹角。透明导光板1朝向光源3的一侧具有与光源3倾斜方向相同的入光斜面11，光源3发出的光可经过透明导光板1后、从透明导光板1的出光面12射出。
需要说明的是，透明导光板1包括入光斜面11和出光面12，入光斜面11和出光面12相交，且入光斜面11和出光面12之间成钝角。
上述倾斜方向指的是：光源放置后，偏离竖直平面的方向。
本发明的实施例提供的显示装置，通过倾斜设置的光源3、以及透明导光板1设置的入光斜面11，使得光源3发出的光尽可能的向透明导光板1背离其出光面12的一面照射。即，使得光源发出的光大部分都直接进入透明导光板1后再射出，避免光源3发出的光直接射入显示装置的阵列结构区域2内。因此，本发明的实施例提供的显示装置，具有较好的显示效果。本发明的实施例提供的显示装置的结构可以有多种。以下例举几种加以说明。
结构一
如图1所示，入光斜面11由透明导光板1背离其出光面12的一面延伸至出光面12，入光斜面11与竖直平面成θ角，光源3向透明导光板1背离 其出光面12的一面倾斜设置，倾斜角度为θ角。光源3包括发光体31和罩设在发光体31上的灯罩32，灯罩32用于将发光体31发出的光线导向透明导光板1的入光斜面11。此时由于光源3是外设于透明导光板1的，为了防止倾斜的光源3发出的光直接照射在显示装置的阵列结构区域2内，可以在发光体31外罩设灯罩32，灯罩32设置可以进一步防止光源3发出的光直接射入阵列结构区域2，使得光源3的出光方向尽可能的垂直于入光斜面11。
进一步的，例如，灯罩32的内侧面上设有反射层5。反射层5的设置可以提高显示装置对光源3的利用率。
例如，上述光源3的倾斜角度θ为大于0度小于90度，这里所指的倾斜角度为：光源放置时，光源偏离竖直平面的角度。例如，光源3的最大倾斜角度比透明导光板1的全反射角大10度，光源3的最小倾斜角度比透明导光板1的全反射角小10度。
例如，以透明导光板1的材料为玻璃为例：玻璃的折射率为1.5，则其全反射角为42度，相应的可以将光源3的最大倾斜角度设置为52度，最小倾斜角度设置为32度，即光源的倾斜角度范围为：32度～52度之间，如32度、34度、36度、38度、40度、42度、44度、46度、48度、50度、52度等，这里就不再一一赘述。上述将光源的倾斜角度设置在上述范围内，可以进一步提高光源的利用率。
例如，透明导光板1的出光面上设有阵列结构区域。即透明导光板1的材料采用玻璃材料的情况下，可以直接在透明导光板的出光面上制膜并对其进行构图形成阵列结构区域。这样可以节省一层衬底基板，减少显示装置的整体厚度。
为了提高显示装置对光源发出的光的利用率，透明导光板1的出光面12上：除与显示装置的阵列结构区域2对应的部分以外的区域上均设有遮挡层4或反射层5，遮挡层4的设置可以防止显示装置出现漏光现象，反射层5的设置可以进一步提高显示装置对光源的利用率。
更进一步的，例如，透明导光板1背离光源3的一面设有反射层5和/或黑色导热层6。反射层5的设置可以进一步提高光的利用率，减少显示装置侧面漏光现象的发生，黑色导热层6的设置可以减少显示装置工作时产生 的热量对阵列结构区域2的影响，具有较好的显示效果。
例如，上述发光体31可以为发光二极管，也可以为冷阴极灯管。
例如，上述反射层可以为反射纸，也可以为铝层或者银层。
结构二
如图2所示，图2为本发明实施例提供的显示装置的第二种部分结构示意图。
透明导光板1朝向光源3的一侧具有开口朝向光源3的V型槽13，光源3位于V型槽13内，V型槽13远离出光面12的一面为入光斜面11。V型槽13的设置可以将光源3容纳在内，从而，可以减少显示装置的边框的宽度，且便于封装光源3，实现窄边框的效果。
例如，该结构的显示装置中的光源3可以只包括：发光体31。
进一步的，例如，V型槽13靠近出光面12的一面设有反射层5或遮挡层4。遮挡层4的设置可以防止显示装置出现漏光现象。反射层5的设置可以进一步提高显示装置对光源的利用率。
上述光源3的倾斜角度为大于0度小于90度，这里所指的倾斜角度为：光源放置时，光源偏离竖直平面的角度。例如，光源3的最大倾斜角度比透明导光板1的全反射角大10度，光源3的最小倾斜角度比透明导光板1的全反射角小10度。
例如，以透明导光板的材料为玻璃为例。玻璃的折射率为1.5，则其全反射角为42度，相应的可以将光源的最大倾斜角度设置为52度，最小倾斜角度设置为32度。即光源的倾斜角度范围为：32度～52度之间。如32度、34度、36度、38度、40度、42度、44度、46度、48度、50度、52度等，这里就不再一一赘述。上述将光源的倾斜角度设置在上述范围内，可以进一步提高光源的利用率。
例如，透明导光板1的出光面上设有阵列结构区域。即透明导光板1的材料采用玻璃材料，可以直接在透明导光板的出光面上制膜并对其进行构图形成阵列结构区域，这样可以节省一层衬底基板，减少显示装置的整体厚度。
例如，为了提高显示装置对光源发出的光的利用率，透明导光板1的出 光面12上：除与显示装置的阵列结构区域2对应的部分以外的区域上均设有遮挡层4或反射层5。遮挡层4的设置可以防止显示装置出现漏光现象。反射层5的设置可以进一步提高显示装置对光源的利用率。
更进一步的，例如，透明导光板1背离光源3的一面设有反射层5和/或黑色导热层6。反射层5的设置可以进一步提高光的利用率，减少显示装置侧面漏光现象的发生。黑色导热层6的设置可以减少显示装置工作时产生的热量对阵列结构区域2的影响，具有较好的显示效果。
例如，上述发光体31可以为发光二极管，也可以为冷阴极灯管。
例如，上述反射层可以为反射纸，也可以为铝层或者银层。

例如，该结构的显示装置中的光源可以包括：发光体31和罩设在发光体31上的灯罩32，灯罩32用于将发光体31发出的光线导向透明导光板1的入光斜面11。灯罩32的设置可以使光源3发出的光尽可能垂直的照射在透明导光板1的入光斜面11上。
例如，V型槽13靠近出光面12的一面设有反射层5或遮挡层4(图中未示出)。遮挡层4的设置可以防止显示装置出现漏光现象。反射层5的设置可以进一步提高显示装置对光源3的利用率。

例如，透明导光板1的出光面上设有阵列结构区域。即透明导光板1的材料采用玻璃材料，在制备阵列结构区域时，可以直接在透明导光板的出光面上制膜并对其进行构图形成该阵列结构区域。这样可以节省一层衬底基板，减少显示装置的整体厚度。
例如，为了提高显示装置对光源发出的光的利用率，透明导光板1的出光面12上：除与显示装置的阵列结构区域2对应的部分以外的区域上均设有遮挡层4或反射层5。遮挡层4的设置可以防止显示装置出现漏光现象。反射层5的设置可以进一步提高显示装置对光源的利用率。
更进一步的，例如，透明导光板1背离光源3的一面设有反射层5和/或黑色导热层6。反射层5的设置可以进一步提高光的利用率，减少显示装置侧面漏光现象的发生。黑色导热层6的设置可以减少显示装置工作时产生的热量对阵列结构区域的影响，具有较好的显示效果。

例如，设定距离可为0.2毫米～0.5毫米。
例如，该结构的显示装置中的光源可以只包括：发光体31。
例如，V型槽13靠近出光面12的一面设有反射层5或遮挡层4(图中未示出)。遮挡层4的设置可以防止显示装置出现漏光现象。反射层5的设置 可以进一步提高显示装置对光源3的利用率。
