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。
除非另作定义, 此处使用的技术术语或者科学术语应当为本发明所属领 域内具有一般技能的人士所理解的通常意义。 本发明专利申请说明书以及权 利要求书中使用的"第一"、 "第二 "以及类似的词语并不表示任何顺序、 数量 或者重要性, 而只是用来区分不同的组成部分。 同样, "一个"、 "一"或者"该" 等类似词语也不表示数量限制, 而是表示存在至少一个。 "包括"或者"包含" 等类似的词语意指出现在该词前面的元件或者物件涵盖出现在该词后面列举 的元件或者物件及其等同, 并不排除其他元件或者物件。 "连接"或者"相连" 等类似的词语并非限定于物理的或者机械的连接,而是可以包括电性的连接, 不管是直接的还是间接的。 "上"、 "下"、 "左"、 "右"等仅用于表示相对位置 关系, 当被描述对象的绝对位置改变后, 则该相对位置关系也可能相应地改 变。
如图 3所示, 本发明的一个实施例提供一种用于制备有机电激发光二极 管 (OLED )透明显示面板的掩膜板 2。 该掩模板 2包括衬底 20、 设置于所 述衬底 20上的多个镂空区域 21和多个遮挡区域 22。 镂空区域 22对应于待 制备的 OLED透明显示面板的阴极, 各个镂空区域 22之间相互连通。
进一步地,每个镂空区域的形状可以为各种适当的形状,例如为三角形、 菱形、 圓形或矩形。 不透光区域之间可以如图 3所示在端部彼此直接连接, 也可以通过连接电极彼此连接。
这些不透光区域例如通过在衬底 20上沉积例如金属 Cr或其氧化物的薄 膜, 然后通过光刻工艺得到。
本实施例所提供的掩膜板包括衬底, 设置于所述衬底上的多个镂空区域 和多个遮挡区域, 镂空对应于待制备的 OLED透明显示面板的阴极, 各个镂 空区域之间相互连通。 通过使用该掩模板, OLED透明显示面板的阴极可以 经过一次构图工艺或者一次蒸镀工艺形成, 所形成的阴极包括多个相互连通 的阴极单元, 因此与现有的方法相比, 采用该掩模板的制备方法减少了制作 阴极的次数, 缩短了阴极制作时间, 降低了成本。 而且所制备的阴极所占面 积较小, 提高了开口率及透过率。
本发明的另一个实施例提供了一种 OLED透明显示面板, 包括: 基板; 设置于所述基板上的阴极, 所述阴极包括多个相互连通的阴极单元, 所述阴 极为使用具有上述任一掩膜板制作而成的。 与图 3所示的掩膜板相对应, 阴 极单元的形状可以为三角形, 且为彼此连接的。
如图 4、 图 5所示, 由于上述实施例所提出的掩膜板的镂空区域的形状 还可以为菱形、 圓形或其他形状(例如矩形) , 那么由该掩膜板制作而成的 显示面板 1的阴极 11所包括的阴极单元 110的形状也可以为三角形、 菱形、 圓形或矩形等。
需要说明的是, 若阴极单元的形状为圓形, 则显示面板的透明显示的效 果与三角形、 菱形、 矩形相比差一些, 因为从图形上来看, 阴极的面积越大, 显示面板的透过率越低。 三角形、 菱形、 矩形阴极面积均能达到 50%的透过 率, 透明效果较好, 而且其均优于现有技术的显示面板的透过率。 但是, 若 需要与现有的彩膜相结合, 则可以优选采用矩形设计, 如能将掩模板区域与 上述实施例中则各阴极单元与各个像素单元的透过窗 ( transmissive window ) 对应, 则可以进一步实现提高显示面板的透过率的目的。
另外, 本实施例的阴极单元的形状还可以为除圓形外的图形 (其主要根 据掩膜板的布局变化而变化) , 那么显示面板的透过率将有一个大幅度的提 高。 但是, 从现有的工艺和材料方面考虑, 阴极面积的缩小将带来显示面板 驱动能力的下降, 体现到显示面板的显示上时, 可能是对比度较低, 颜色异 常等现象, 若未来在阴极制成材料和显示面板特性方面都能得到提升, 也就 是说较 d、面积的阴极完全能够实现正常驱动, 那么采用除圓形外的图形也会 是提高显示面板的透过率的一个较好的手段。
进一步地, 本发明实施例的显示面板, 还可以包括设置于所述基板上的 第一传输层、 发光层、 第二传输层及阳极。
作为本发明的显示面板的一种实施例, 如图 6所示, 本发明实施例的显 示面板 1可以包括: 基板 10; 设置于基板 10上的阳极 12; 设置于阳极 12 上的第一传输层 13; 设置于第一传输层 13上的发光层 14; 设置于发光层 14 上的第二传输层 15;设置于第二传输层 15上的阴极 11。 阴极 11包括多个相 互连通的阴极单元,该阴极 11为使用具有上述任一实施例的掩膜板制作而成 的。
该发光层可以为各种可用的发光层, 例如可以发红、 绿、 蓝或白光等。 例如, 第一传输层为空穴传输层, 第二传输层还可以为电子传输层。 本 发明的实施例中, 在阴阳两个电极之间施加合适的偏压后, 电子和空穴分别 从阴极和阳极注入, 由于在有机层中空穴的迁移率高于电子, 故空穴和电子 通常在靠近阴极的发光层的界面发生复合, 进而实现显示面板发光。
需要说明的是, 上述作为本发明的一种实施例的显示面板为顶部发光的
OLED透明显示面板, 而作为本发明的另一种实施例的显示面板可以为底部 发光的 OLED透明显示面板。 在此实施例中, 阴极可以设置于基板与第一传 输层之间, 阳极可以设置于第二传输层上, 而阴极的结构与上述实施例相同, 故也在本发明的保护范围内。
进一步地, 第一传输层或第二传输层还可以为由阻挡层、 注入层和传输 层叠加而形成的多层结构。
进一步地, 发光层的材料可以为单一的有机物或掺杂的有机物。
进一步地, 掺杂的有机物可以为荧光材料或磷光材料。
本发明实施例所提供的显示面板包括基板和设置于基板上的阴极, 该阴 极包括多个相互连通的阴极单元。 由于阴极可以经过一次构图工艺或者一次 蒸镀工艺形成, 所形成的阴极包括多个相互连通的阴极单元, 与现有的方法 相比减少了制作阴极的次数, 缩短了阴极制作时间, 降低了成本, 且阴极所 占面积较小, 提高了开口率及透过率。
本发明的另一个实施例提供一种 OLED透明显示面板的制造方法,包括: 采用一次构图工艺在基板上形成阴极, 所述阴极包括多个相互连通的阴极单 元。
这里构图工艺为光刻构图方法, 包括待构图的结构层上涂覆光刻胶, 对 光刻胶使用掩模板进行曝光, 将曝光后的光刻胶显影得到光刻胶掩模, 以及 使用得到的光刻胶掩模作为刻蚀掩模对结构层进行刻蚀形成图案, 之后除去 光刻胶掩模。 所使用的例如正性光刻胶。 在同一次构图工艺中, 对于待构图 的结构层上涂覆的光刻胶, 可以采用掩模板每次曝光部分区域的方式逐步进 行来将全部光刻胶曝光, 在显影之后, 进行同一刻蚀工艺将结构层形成为需 要的图案。
本发明的一个实施例提供的一种 OLED透明显示面板的制造方法, 该方 法包括如下步骤。
5101、 选取基板。
可以选取玻璃、 石英片、 硅片、 金属片、 聚对苯二曱酸乙二醇脂
( Polyethylene Terephthalate, PET )或表面经处理后的聚合物软膜作为基板。
5102、 在基板上形成阳极。
OLED的阳极通常采用铟锡氧化物(Indium Tin Oxide, ITO ) 、 铟辞氧 化物( Indium Zinc Oxide, IZO )或氧化辞铝或铝掺杂的氧化辞( Al-doped ZnO, AZO )等材料。
5103、 采用化学气相沉积、 物理气相沉积 (Physical Vapor Deposition, PVD)或旋涂的方法, 在形成阳极的基板上形成第一传输层。
第一传输层为空穴传输层, 空穴传输层可以采用以联苯为核心的三芳香 胺, 如 N, N'-bis(naphthalen- 1 -y)-N , N'-bis(phenyl)benzidin(NPB) , 二胺联苯 衍生物等材料, 厚度一般在 10nm至 50nm的范围内。
5104、 采用蒸镀、 旋涂或喷墨打印的方法, 在形成第一传输层的基板上 形成发光层。
发光层可以为单一的有机物, 如 8羟基喹啉铝 (Alq3)、 红荧烯 (Rubrene) 等, 该有机物也可以含有掺杂物, 如 4, 4'-Ν, Ν'-二咔唑 -联苯 (CBP)掺入红 荧烯 (Rubrene)等, 或磷光材料, 如 fac-三 (2-苯基吡啶)铱 [Ir(ppy)3]等, 或荧光 材料, 该发光层的厚度一般在 lnm至 50nm的范围内。
当所制备 OLED显示面板的每个像素例如由红、绿和蓝色子像素构成时, 则可以使用掩模板进行沉积工艺, 例如依次在基板上沉积形成红色发光层材 料、 绿色发光层材料和蓝色发光层材料。
5105、 采用化学气相沉积、 PVD或旋涂的方法, 在形成发光层的基板上 形成第二传输层。
本发明实施例中, 步骤 105中形成的第二传输层可以为电子传输层, 例 如, 该电子传输层可以是 Alq3、 2, 2', 2 -(1 , 3 ,
5-benzenetriyl)tris [ 1 -phenyl- 1 H-benzimidazole] (TPBI)、 4 , 7-diphenyl- 1 , lO-phenanthroline(Bphen)掺入金属铯 (Cs)等材料, 其厚度一般在 10匪至 lOOnm的范围内。
5106、 采用一次构图工艺在形成第二传输层的基板上形成阴极, 阴极包 括多个相互连通的阴极单元。
如下所述, S106的一个具体示例包括子步骤 S106a-S106d:
S106a、 在所述基板上形成阴极薄膜。
S106b、 在所述阴极薄膜上形成光刻胶。
S106c、对所述光刻胶进行曝光,显影后形成光刻胶保留区域和光刻胶去 除区域, 所述光刻胶保留区域对应于所述阴极。
例如, 利用上述实施例的掩膜板, 对所述光刻胶进行曝光, 显影后形成 光刻胶保留区域和光刻胶去除区域, 所述光刻胶保留区域对应于所述阴极。
在此步骤中, 曝光过程中采用负性光刻胶, 在曝光后, 掩膜板镂空区域 对应为光刻胶保留区域, 遮挡区域对应的为光刻胶去除区域。
S106d、 刻蚀所述光刻胶去除区域对应的所述阴极薄膜, 以形成所述阴 极。 所采用的刻蚀工艺例如可以为干刻工艺, 也可以为湿刻工艺。
要想有效地往有机材料中注入电子, 阴极材料的功函数必须足够低, 用 低功函数金属作阴极的 OLED器件的响应更快。 目前, 在 OLED器件中获 得应用的单层金属阴极有 Mg ( 3.7 eV ) , Li ( 2.9 eV ) , Ca ( 2.9 eV ) , Sr ( 2.4 eV ) , Na ( 2.3 eV ) , Cs ( 2.1 eV ) 、 Gd等。 为了防止水和氧气对低 功函数金属阴极产生不利影响, 还可以采用合金阴极 Ca/Al , Mg/Ag , Mg/MgAg, Gd/Al, Al Li, Sn/Al和 Ag/Al等。 在该实施例中的 OLED的阴 极可以是镁铝合金、 镁银合金、 钙银合金等, 其厚度一般在 10匪至 200匪 范围内。
若制备得到的阴极单元之间存在导通不良的情况, 则可以使用点连接的 方法, 将存在导通不良的情况的阴极单元与其他正常的阴极单元连接, 以保 证显示面板整体上能够正常工作。
至此, 制造完成了如图 6所示的显示面板。
最后, 还可以利用封盖或薄膜封装层将上述整个显示装置进行封装, 用 以防止水和氧对有机层造成侵蚀。
本发明的另一实施例还提供了的另一种显示面板的制造方法, 与上述制 造方法的区别在于:
S106步骤也可以采用一次蒸镀工艺形成,仅需在蒸镀时采用上述的掩膜 板, 多个镂空区域对应 OLED面板的多个阴极单元, 同时由于多个镂空区域 是彼此连通的, 因此蒸镀之后的基板上的各个阴极单元也是彼此连通的, 形 成整体连接的阴极。
对于阴极材料的选择可同样如上所述。
最后, 可以利用封盖或薄膜封装层将上述整个显示装置进行封装, 用以 防止水和氧对有机层造成侵独。
本发明实施例所提供的显示面板的制造方法, 采用一次构图工艺在基板 上形成阴极, 阴极包括多个相互连通的阴极单元。 由于阴极是经过一次构图 工艺或者一次蒸镀工艺形成的,所形成的阴极包括多个相互连通的阴极单元, 与现有技术相比减少了制作阴极的次数,缩短了阴极制作时间,降低了成本。
本发明实施例中, 在阴阳两个电极之间施加合适的偏压后, 电子和空穴 分别从阴极和阳极注入, 由于在有机层中空穴的迁移率高于电子, 故空穴和 电子通常在靠近阴极的发光层的界面发生复合, 进而实现显示面板发光。 本 发明的显示面板的制造方法可实现阴极的一次成形, 减小阴极的面积并且依 然能够实现阴极的导通, 该方法大大降低了 OLED阴极的制作成本, 单次无 交叠的沉积使得阴极更加平整化, 更好地实现了导通效果。
以上所述仅是本发明的示范性实施方式, 而非用于限制本发明的保护范 围, 本发明的保护范围由所附的权利要求确定。
