Description

一种显示器件及其制备方法 技术领域
本发明涉及显示技术领域,具体涉及一种显示器件及其制备方法。
背景技术
OLED(英文全称:Organic Light-Emitting Diode, 简称OLED)器件又称为有机电激光显示装置、有机发光半导体。OLED的基本结构是由一薄而透明具有半导体特性的铟锡氧化物(ITO)与电力之正极相连,再加上另一个金属面阴极,包成如三明治的结构。整个结构层中包括了:空穴传输层(HTL)、发光层(EL)与电子传输层(ETL)。当电力供应至适当电压时,正极空穴与面阴极电荷就会在发光层中结合,在库伦力的作用下以一定几率复合形成处于激发态的激子(电子-空穴对),而此激发态在通常的环境中是不稳定的,激发态的激子复合并将能量传递给发光材料,使其从基态能级跃迁为激发态,激发态能量通过辐射驰豫过程产生光子,释放出光能,产生光亮,依其配方不同产生红、绿和蓝RGB三基色,构成基本色彩。
首先OLED的特性是自己发光,不像薄膜晶体管液晶显示装置(英文全称:Thin film transistor-liquid crystal display,简称TFT-LCD)需要背光,因此可视度和亮度均高。其次OLED具有电压需求低、省电效率高、反应快、重量轻、厚度薄,构造简单,成本低、广视角、几乎无穷高的对比度、较低耗电、极高反应速度等优点,已经成为当今最重要的显示技术之一,正在逐步替代 TFT-LCD,有望成为继LCD之后的下一代主流显示技术。
偏光片(POL)能够有效地降低强光下面板的反射率,却损失了接近58%的出光。这对于OLED来说,极大地增加了其寿命负担;另一方面,偏光片厚度较大、材质脆,不利于动态弯折产品的开发。为了开发基于OLED显示技术的动态弯折产品,必须导入新材料、新技术以及新工艺替代偏光片。
技术问题
使用彩膜(Color Filter)替代偏光片(POL)被归属为POL-less(去偏光片)技术。传统的DOT(英文全称:Direct on-cell touch的,内置触控)和POL-less工艺结合需要考虑DOT和POL-less CF相对位置关系,若将DOT置于POL-less上方,虽然增加POL-less的透过率,但是DOT的Metal Mesh Line(金属网线)由于对外界环境光的反射率高,太阳光下显示器的反射率仍然较高,甚至于会看到Metal Mesh Line的影子,从而影响用户使用体验。若要将DOT至于POL-less下方,虽然POL-less中的BM可以遮挡DOT的Metal Mesh Line,但是由于POL-less膜层距离EL膜层间隔TFE和DOT,距离较大,光线会很大部分被BM吸收或者阻挡,从而严重影响显示器的透过率。由此可见,POL-less和DOT技术若不能很好结合,则无法达到替代传统圆偏光片,实现柔性显示的目标。因此需要寻求一种新型的显示器件以解决上述问题。
技术解决方案
本发明的一个目的是提供一种显示器件及其制备方法,其能够解决现有技术中的DOT和POL-less的结合中存在的问题,保证显示器件低反射率和高透过率的同时,减少一道曝光制程和一道剥离制程,极大的降低生产成本。

如图3所示,本实施方式与实施方式一所述的显示器件100存在的区别之处在于:其中所述凹槽13由所述黑色矩阵层11背向所述阵列基板层1的一侧表面凹陷至所述缓冲层7中。首先,通过将黑色矩阵层11直接设置在所述第二金属层10上,缩短了黑色矩阵层11与发光层4之间的距离,避免了光线的损失,提高光线的透过率;其次,所述黑色矩阵层11可以遮挡第二金属层10,避免由第二金属层11的高反射率产生的影响客户体验度的现象。其中所述黑色矩阵层11直接设置在所述第二金属层10上,利用黑色矩阵层11充当第二金属层10用来蚀刻填充色阻材料的凹槽13的PR掩膜板,在保证显示器件的低反射率和高透过率的同时,可以减少一道曝光和剥离制程,从而降低生产成本。
如图4所示,本发明的另一个实施方式还提供了一种制备本发明所涉及的显示器件100的制备方法,其中包括以下步骤:步骤S1,制备阵列基板层1;步骤S2,在所述阵列基板层1上制备发光层4;步骤S3,在所述发光层4上制备所述封装层6;步骤S4,在所述封装层6上制备缓冲层7;步骤S5,在所述缓冲层7上制备第一金属层8;步骤S6,在所述第一金属层8上覆盖制备绝缘层9;步骤S7,在所述绝缘层9上制备第二金属层10,所述第二金属层10通过过孔与所述第一金属层8连接;步骤S8,在所述第二金属层10上制备黑色矩阵层11,通过曝光、显影、烘烤制程技术在对应于所述发光层4的位置处向下凹陷形成凹槽13;步骤S9,在所述凹槽13内填充有色阻材料。
其中所述步骤S8中的凹槽13可以通过对所述黑色矩阵层11以及所述第二金属层10进行刻蚀得到。
其中所述步骤S8中的凹槽13也可以通过对所述黑色矩阵层11、所述第二金属层10以及所述绝缘层9进行刻蚀得到。
其中所述步骤S8中的凹槽13还可以通过对所述黑色矩阵层11、所述第二金属层10、所述绝缘层9以及所述缓冲层7进行刻蚀得到。
通过上述方法制备的显示器件100,首先,通过将黑色矩阵层11直接设置在所述第二金属层10上,缩短了黑色矩阵层11与发光层4之间的距离,避免了光线的损失,提高光线的透过率;其次,所述黑色矩阵层11可以遮挡第二金属层10,避免由第二金属层11的高反射率产生的影响客户体验度的现象。其中所述黑色矩阵层11直接设置在所述第二金属层10上,利用黑色矩阵层11充当第二金属层10用来蚀刻填充色阻材料的凹槽13的PR掩膜板,在保证显示器件的低反射率和高透过率的同时,可以减少一道曝光和剥离制程,从而降低生产成本。
以上对本发明所提供的显示器件及其制备方法进行了详细介绍。应理解,本文所述的示例性实施方式应仅被认为是描述性的,用于帮助理解本发明的方法及其核心思想,而并不用于限制本发明。在每个示例性实施方式中对特征或方面的描述通常应被视作适用于其他示例性实施例中的类似特征或方面。尽管参考示例性实施例描述了本发明,但可建议所属领域的技术人员进行各种变化和更改。本发明意图涵盖所附权利要求书的范围内的这些变化和更改,凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等,均应包含在本发明的保护范围之内。
