如图2、图3所示,所述走线区13设置于所述主像素区11和所述次像素区12之间,且位于所述次显示区102。即,走线区13包围所述主像素区11,所述次像素区12包围所述走线区13。所述走线区13主要用于放置显示面板1的走线。
如图2、图3所示,所述框胶区14设置于所述次像素区12远离所述主像素区11的一侧,且位于所述次显示区102。即,所述框胶区14包围所述次像素区12。所述框胶区14主要用于放置显示面板1内的框胶,所述框胶区14也可以放置显示面板1的走线。
如图2、图3所示,所述侧胶区15设置于所述框胶区14远离所述次像素区12的一侧,且位于所述次显示区102。即,所述侧胶区15包围所述框胶区14。
如图2所示,所述次显示区102包括:两个第一次显示区1021和两个第二次显示区1022。
其中,两个第一次显示区1021相互平行,且沿第一方向X延伸。
其中,两个第二次显示区1022相互平行,且沿第二方向Y延伸。所述第二方向Y垂直于所述第一方向X。本实施例中,两个所述第二次显示区1022均设置于两个所述第一次显示区1021之间。
如图2、图3及图4所示,所述显示面板1包括:多个主像素单元16、多个第一次像素单元17以及多个第二次像素单元18。
其中,多个所述主像素单元16位于所述主显示区101的主像素区11。
其中,多个第一次像素单元17位于所述第一次显示区1021。
其中,多个第二次像素单元18位于所述第二次显示区1022。
如图3-图5所示,其中,光学元件2设置于所述显示面板1上,且覆盖所述次显示区102。所述光学元件2用于放大所述次显示区102的显示面板1发出、反射出或者透射出的光线的出光角度。
通过在主显示区101外围的次显示区102(现有技术中不显示的边框区)设置次像素区12,通过在次像素区12上设置光学元件2。利用光学元件2放大所述次显示区102的显示面板1发出、反射出或者透射出的光线的出光角度,将边框区变成与主显示区101显示效果相同的次显示区102,进而实现真正的无边框显示效果。
如图3-图5所示,本实施例中,所述光学元件2为平凸透镜,所述光学元件2远离所述显示面板1的一侧的顶面21为曲面,所述光学元件2靠近所述显示面板1的一侧的底面22为平面。所述光学元件2还包括垂直连接于所述底面22和顶面21之间的两个端面23。在平行于所述光学元件2的所述端面23的截面上,所述光学元件2放大所述次显示区102的显示面板1发出、反射出或者透射出的光线的出光角度。
其中,所述光学元件2完全覆盖所述走线区13、次像素区12、框胶区14以及侧胶区15。即,光学元件2完全覆盖所述次显示区12,进而在多个显示装置100拼接形成拼接显示装置200时,可以实现无缝显示。
如图3-图8所示,所述光学元件2包括第一光学元件210以及第二光学元件220。
如图2、图3、图5、图6所示,第一光学元件210覆盖所述第一次显示区1021,且沿着所述第一方向X延伸。所述第一光学元件210的平行于所述第一方向X的中心轴与所述第一次显示区1021的次像素区12的平行于所述第一方向X的中心轴重合。所述第一光学元件210的端面23与所述第一方向X相互垂直。即,本实施例中,在平行于所述第一光学元件210的所述端面23的截面(ZY平面)上,所述第一光学元件210放大所述第一次显示区1021的第一次像素单元17透射出的光线的出光角度。在其他实施例中,在平行于所述第一光学元件210的所述端面23的截面(ZY平面)上,所述第一光学元件210可以对所述第一次显示区1021的第一次像素单元17反射出的环境光的出光角度进行放大。当所述第一次像素单元17为OLED、Mini LED或者Micro LED时,在平行于所述第一光学元件210的所述端面23的截面(ZY平面)上,所述第一光学元件210可以对所述第一次显示区1021的第一次像素单元17发射出的光线的出光角度进行放大。
如图2、图3、图7、图8所示,第二光学元件220覆盖所述第二次显示区1022,且沿着所述第二方向Y延伸。所述第二光学元件220的平行于所述第二方向Y的中心轴与所述第二次显示区1022的次像素区12的平行于所述第二方向Y的中心轴重合。所述第二光学元件220的端面与23所述第二方向Y相互垂直。即,本实施例中,在平行于所述第二光学元件220的所述端面23的截面(ZX平面)上,所述第二光学元件220放大所述第二次显示区1022的第二次像素单元18透射出的光线的出光角度。在其他实施例中,在平行于所述第二光学元件220的所述端面23的截面(ZX平面)上,所述第一光学元件210可以对所述第一次显示区1021的第一次像素单元17反射出的环境光的出光角度进行放大。当所述第一次像素单元17为OLED、Mini LED或者Micro LED时,在平行于所述第二光学元件220的所述端面23的截面(ZX平面)上,所述第一光学元件210可以对所述第一次显示区1021的第一次像素单元17发射出的光线的出光角度进行放大。
如图2、图3、图6所示,所述第一次像素单元17在第一方向X上的长度与所述主像素单元16在第一方向X上的长度相同,所述第一次像素单元17在第二方向Y上的长度小于所述主像素单元16在第二方向Y上的长度。通过第一光学元件210放大所述第一次显示区1021的第一次像素单元17在ZY平面上的光线的出光角度,使得放大后的第一次像素单元17在第一方向X的显示长度等于主像素单元16在第一方向X上的显示长度;放大后的第一次像素单元17在第二方向Y的显示长度等于主像素单元16在第二方向Y上的显示长度,达到第一次显示区1021与主显示区101的显示效果相同的目的。
如图2、图4、图8所示,所述第二次像素单元18在第二方向Y上的长度与所述主像素单元16在第二方向Y上的长度相同,所述第二次像素单元18在第一方向X上的长度小于所述主像素单元16在第一方向X上的长度。通过第二光学元件220放大所述第二次显示区1022的第二次像素单元18在ZX平面上的光线的出光角度,使得放大后的第二次像素单元18在第二方向Y的显示长度等于主像素单元16在第二方向Y上的显示长度;放大后的第二次像素单元18在第一方向X的显示长度等于主像素单元16在第一方向X上的显示长度,达到第二次显示区1022与主显示区101的显示效果相同的目的,最中实现次显示区102与主显示区101显示效果相同的目的。
其中,背光源3设置于所述显示面板1远离所述光学元件2的一侧,且位于所述主显示区101和所述次显示区102。
由于次像素区12的第一次像素单元17以及第二次像素单元18需要光学元件2对其发出的光线进行放大,光学元件2会对第一次像素单元17以及第二次像素单元18发出的光线亮度造成衰减。而且,第一像素单元17在第二方向Y上的长度小于主像素单元16在第二方向Y上的长度;第二次像素单元18在第一方向X上的长度小于所述主像素单元16在第一方向X上的长度,导致次像素区12的发光亮度小于主像素区11。因此,将与所述次像素区12对应的所述背光源3的亮度大于与所述主像素区11对应的所述背光源3的亮度。由此提升显示装置100的显示均一性,提升显示装置100的显示效果。
如果背光源3采用直下式背光源,此时可以通过增加次像素区12的背光源3的亮度。如果背光源3采用侧入式背光源,可以增大导光板在次像素区的反射点,进而增加次像素区12的背光源3的亮度。
实施例2
如图9所示,本实施例包括了实施例1的大部分技术特征,本实施例与实施例1的区别在于:本实施例中,两个所述第一次显示区1021均设置于两个所述第二次显示区1022之间。
本实施例通过在主显示区101外围的次显示区102(现有技术中不显示的边框区)设置次像素区12,通过在次像素区12上设置光学元件2。利用光学元件2放大所述次显示区102的显示面板1发出、反射出或者透射出的光线的出光角度,将边框区变成与主显示区101显示效果相同的次显示区102,进而实现真正的无边框显示效果。
实施例3
如图10所示,本实施例提供了一种拼接显示装置200。拼接显示装置200包括多个相互拼接的显示装置100。所述显示装置100为实施例1的显示装置100或者实施例2的显示装置100。
由于显示装置100的光学元件2完全覆盖所述走线区13、次像素区12、框胶区14以及侧胶区15。即,光学元件2完全覆盖所述次显示区12,使得实施例1的显示装置100和实施例2的显示装置100均为无边框显示装置,可以使得本实施例的拼接显示装置200的拼接缝201处正常显示,提升拼接显示装置200的显示效果,提升拼接显示装置200的产品竞争力及经营利润。
