Description

微型LED显示面板及其制备方法
技术领域
本发明涉及一种微型LED显示面板及该种微型LED显示面板的制备方法。
背景技术
现有的微型LED(micro light emitting diode)显示面板包括多个像素单元。每一个像素单元通常包括三个子像素,每一个像素单元中的三个子像素分别发红光、蓝光、绿光。然而,现有技术中,像素单元中的子像素通常为水平排布,由于每一个子像素尺寸极小(通常不超过100微米),导致微型LED显示面板的加工精度要求很高。
发明内容
鉴于此,有必要提供一种微型LED显示面板及其制备方法,其对加工精度要求相对较低,便于加工。
一种微型LED显示面板,其包括层叠设置的蓝色LED层、绿色LED层和红色LED层,所述蓝色LED层形成间隔设置的多个蓝色微型LED,每一个蓝色微型LED定义一个蓝色子像素;所述绿色LED层形成间隔设置的多个绿色微型LED,每一个绿色微型LED定义一个绿色子像素;所述红色LED层形成间隔设置的多个红色微型LED,每一个红色微型LED定义一个红色子像素;每一个蓝色子像素、每一个绿色子像素、和每一个红色子像素为相互错开的。
一种微型LED显示面板的制备方法,其包括:
形成蓝色LED层,所述蓝色LED层形成间隔设置的多个蓝色微型LED,每一个蓝色微型LED定义一个蓝色子像素;
形成绿色LED层,所述绿色LED层形成间隔设置的多个绿色微型LED,每一个绿色微型LED定义一个绿色子像素;
形成红色LED层,所述红色LED层形成间隔设置的多个红色微型LED,每一个红色微型LED定义一个红色子像素;
层叠所述蓝色LED层、所述绿色LED层、和所述红色LED层,并使每一个蓝色子像素、每一个绿色子像素、和每一个红色子像素相互错开。
本发明通过将不同颜色的微型LED层进行层叠设置,使每一个像素包括上下层叠且相互错开的一个蓝色子像素、一个绿色子像素和一个红色子像素,该种结构的微型LED显示面板更方便加工。
附图说明
图1是本发明第一实施方式的微型LED显示面板的剖面示意图。
图2是本发明第二实施方式的微型LED显示面板的剖面示意图。
主要元件符号说明
如下具体实施方式将结合上述附图进一步说明本发明。
具体实施方式
附图中示出了本发明的实施例,本发明可以通过多种不同形式实现,而并不应解释为仅局限于这里所阐述的实施例。相反,提供这些实施例是为了使本发明更为全面和完整的公开,并使本领域的技术人员更充分地了解本发明的范围。为了清晰可见,在图中,层和区域的尺寸被放大了。
可以理解,尽管第一、第二等这些术语可以在这里使用来描述各种元件、组件、区域、层和/或部分,但这些元件、组件、区域、层和/或部分不应仅限于这些术语。这些术语只是被用来区分元件、组件、区域、层和/或部分与另外的元件、组件、区域、层和/或部分。因此,只要不脱离本发明的教导,下面所讨论的第一部分、组件、区域、层和/或部分可以被称为第二元件、组件、区域、层和/或部分。
这里所用的专有名词仅用于描述特定的实施例而并非意图限定本发明。如这里所用的,单数形式“一”、“一个”和“该”也意图涵盖复数形式,除非上下文清楚指明是其它情况。还应该理解,当在说明书中使用术语“包含”、“包括”时,指明了所述特征、整体、步骤、操作、元件和/或部件的存在,但是不排除一个或多个其它特征、整体、步骤、操作、元件和/或部件的存在。
本文中的“微型LED”是指尺寸小于等于几个毫米(如几个毫米、几百微米或小于等于100微米)的LED。
这里参考剖面图描述本发明的实施例,这些剖面图是本发明理想化的实施例(和中间构造)的示意图。因而,由于制造工艺和/或公差而导致的图示的形状不同是可以预见的。因此,本发明的实施例不应解释为限于这里图示的区域的特定形状,而应包括例如由于制造而产生的形状的偏差。图中所示的区域本身仅是示意性的,它们的形状并非用于图示装置的实际形状,并且并非用于限制本发明的范围。
除非另外定义,这里所使用的所有术语(包括技术和科学术语)具有与本发明所述领域的普通技术人员所通常理解的含义相同的含义。还应当理解,比如在通用的辞典中所定义的那些的术语,应解释为具有与它们在相关领域的环境中的含义相一致的含义,而不应以过度理想化或过度正式的含义来解释,除非在本文中明确地定义。
第一实施例
