在一个示例中, 所述颜色转换层为荧光材料。
本发明的至少一个实施例还提供了一种显示装置, 包括上述任一的彩膜 基板。 附图说明
以下将结合附图对本发明的实施例进行更详细的说明, 以使本领域普通 技术人员更加清楚地理解本发明, 其中:
图 1是本发明实施例的一种彩膜基板示意图;
图 2是釆用图 1中彩膜基板的显示装置避免显示颜色泛白的原理图。 具体实施方式
为使本发明的实施例的目的、 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的实施例的技术方案进行清楚、 完整的描述。 显 然, 所描述的实施例仅是本发明的一部分示例性实施例, 而不是全部的实施 例。 基于所描述的本发明的示例性实施例, 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它实施例都属于本发明的保护范围。
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,而不排除其他元件或者物件。 "上"、 "下"、 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。
本发明的实施例提供一种具有潜在的能满足新颖的显示器的各方面要 求, 而且结构简单, 具有高能效、 极高透明性并且色彩更加鲜明的基于集成 的光学元件的显示器及其使用的彩膜基板。
如图 1和 2所示, 本发明的实施例提供的彩膜基板包括: 衬底基板 510及形 成在所述衬底基板上的彩色滤光片 520, 依次形成在所述彩色滤光片 520背离 所述衬底基板一侧的颜色转换层 100、 第一折射率膜层 200、 第二折射率膜层 300和第三折射率膜层 400。 第二折射率膜层 300的折射率大于第三折射率膜层 400的折射率和在未加电情况下的第一折射率膜层 200的折射率, 小于加电情 况下的第一折射率膜层 200的折射率。 所述彩色滤光片 520配置来吸收外部光 线中与所述颜色转换层 100发生光致发光反应的部分光线。 第一折射率膜层 200可以为液晶层。
颜色转换层 100为由转换不同色光(如: 红、 绿色光) 的荧光材料形成 的阵列, 且与彩色滤光片的相同颜色对应。
当对第一折射率膜层 200不加电的情况下, 颜色转换层 100使光向着位 于折射率低的第一折射率膜层 200与第三折射率膜层 400之间的具有高折射 率的第二折射率膜层 300以全反射方式移动。 当对第一折射率膜层 200加电 时, 第一折射率膜层 200的折射率升高, 从而使全反射条件被打破, 光被提 取出来, 并向着颜色转换层 100入射, 从而最终获得所需波长的光。
但是当普通的白色外界光入射到显示器装置时, 外界光向着颜色转换层
100入射, 一部分外界光与颜色转换材料(CCM )发生光致发光反应, 即外 界白光的特定波长的光^^色转换层 100的荧光体材料吸收再放出, 会使得 显示装置内部放出的影像变得模糊。 如图 2所示, 彩色滤光片 520配置来吸 收外界光线中与所述颜色转换层 100发生光致发光反应的部分光线, 即外界 光通过彩色滤光片 520时, 仅允许特定波长区域的光通过彩色滤光片 520, 即彩色滤光片 520仅允许不发生光致反应的成分通过, 而剩余的波长成分被 彩色滤光片吸收, 从而避免了外界白光照射到颜色转换层 100后, 光致发光 反应导致的泛白现象, 以使显示色彩更加鲜明。
本发明的至少一个实施例还提供了一种制作上述彩膜基板的方法, 包括: 在衬底基板上制作彩色滤光片, 以及在所述彩色滤光片背离所述衬底基板一 侧依次形成颜色转换层、 第一折射率膜层、 第二折射率膜层和第三折射率膜 层。 所述第二折射率膜层的折射率大于第三折射率膜层的折射率和在未加电 情况下的第一折射率膜层的折射率, 小于加电情况下的第一折射率膜层的折 射率。 所述彩色滤光片配置来吸收外部光线中与所述颜色转换层发生光致发 光反应的部分光线。
第一折射率膜层为液晶层, 颜色转换层为荧光材料。
本实施例中, 颜色转换层的制作方法包括: 在所述彩色滤光片对应的区 域形成与该区域的彩色滤光片颜色相同的颜色转换单元, 不同颜色的颜色转 换单元共同形成颜色转换层。
本发明的实施例还提供了一种包括所述彩膜基板的显示装置, 该显示装 置具有较好的色彩鲜明度。
本发明的实施例通过在彩膜基板上形成颜色转换层、 第一折射率膜层、 第二折射率膜层和第三折射率膜层, 外界白光通过该彩色滤光片时, 仅允许 特定波长区域的光通过彩色滤光片, 即仅允许不发生光致反应的成分通过, 而剩余的波长成分被彩色滤光片吸收, 这样在有外界白光照射到颜色转换层 的情况下, 显示装置也不会出现显示颜色泛白的现象, 从而使显示色彩更加 鲜明。
以上实施方式仅用于说明本发明, 而并非对本发明的限制, 有关技术领 域的普通技术人员, 在不脱离本发明的精神和范围的情况下, 还可以做出各 种变化和变型, 而这些变化和变型和所有等同的技术方案也应属于本发明的 范畴, 本发明的专利保护范围由权利要求限定。
