具体实施方式
以下结合附图对本发明的实施例进行详细说明,但是本发明可以由权利要求限定和覆盖的多种不同方式实施。
本发明实施例所述的显示屏,包括第一基板、第二基板和设置于所述第一基板和所述第二基板之间的液晶层;
所述第一基板包括:基板、设置在该基板上的光学膜组和直接设置于该光学膜组上的多个像素单元;
所述第二基板包括阵列基板。
本发明实施例所述的显示屏,采用将BLU(Black Light Unit,背光源)以光学膜组的方式直接集成到显示屏内部的第一基板上,可减小显示屏整体厚度重量。
在一实施例所述的显示屏中,所述第二基板还包括:覆盖于所述阵列基板上的平坦层,以及设置于该平坦层上的彩膜层,这样设置于所述阵列基板上的TFT在上侧以CF(Color Filter,彩膜)层覆盖可有效避免光照对TFT特性的影响以及扫描纹的不良的产生。
本发明该实施例所述的显示屏,通过将CF(Color Filter,彩膜)层直接制备在Array(阵列)基板上,形成第二基板(在本实施例中也可以称为彩色滤光阵列基板),同时在另一侧玻基板上制备光学膜层,形成第一基板(也可以称为背光基板),然后将所述彩色滤光阵列基板和所述背光基板对盒而制成液晶显示屏,最终实现背光源与液晶面板一体化,并且在该实施例所述的显示屏中,阵列走线与彩膜层同侧,阵列走线完全处于彩膜层的覆盖之下,可以避免因为光照引起的TFT特性变化导致的扫描纹,同时一体化设计可以减少整体膜组的厚度。
优选的,所述彩膜层上设置有第一偏光膜层;
所述第一基板还包括:
设置于所述光学膜组上的第二偏光膜层,所述第二偏光膜层的偏光角度与所述第一偏光膜层的偏光角度相匹配;
以及,设置于所述第二偏光膜层上的配向膜层,该配向膜层按照预定液晶预倾角进行配向。
在一具体实施例中,所述光学膜组包括:
设置于所述基板上的导光板;
设置于该导光板上的棱镜膜层,该棱镜膜层上通过曝光显影形成有棱纹;
以及,设置于该棱镜膜层上的扩散膜层;
所述导光板包括:
形成于所述基板上的反射层;
形成于该反射层上的ITO(氧化铟锡)层,该ITO层中的网点位置通过LGP(导光板)网点掩膜形成有刻蚀孔;
以及,涂覆于该ITO层上的导光膜层,该导光膜层在该ITO层的刻蚀孔内形成网点结构,该导光膜层表面平坦。
在该实施例中,导光膜层面是需要有聚光的网点的,为了成型出网点构造,采用ITO刻蚀出网孔,待下一步制作导光膜层时,导光膜层材质直接填充进入网孔内部形成网点。导光膜层中网点是通过ITO层先刻蚀出网点孔洞结构,然后沉积导光膜层时,导光膜材质进入网点孔洞而形成带网点的导光膜层结构。其中使用反射层可以调整光的出射方向,使光线正面出射;使用扩散膜层可以提高出光的均一性。
在一实施例中,所述光学膜组包括:
形成于所述基板上的反射层;
形成于该反射层上的下电极层;
