Description

显示面板及其制造方法和显示装置 技术领域
本发明属于液晶显示技术领域， 具体涉及一种显示面板及其 制造方法和显示装置。 背景技术
液晶显示装置具有轻薄、 功耗小、 数字化等优点， 目前在市 场上越来越受到广泛应用。 由于液晶本身不发光， 也无法依赖自 然光采光， 因此必须采用背光源以获得稳定、 清晰的显示。 一般 来说， 背光源的电能来源于外接的电池， 比如锂电池， 而电池的 储电量有限， 每次使用完后需要充电， 给使用者带来不便。
太阳能电池是利用光伏效应将太阳能转化为电能的一种装 置。 如图 1所述， 在常规的太阳能电池中， 当 N型半导体材料和 P型半导体材料接触后，导电粒子会发生扩散和漂移，从而在两种 半导体材料的界面处形成由 N型指向 P型的内建电场。 当光照在 太阳能电池的表面后， 光子提供能量， 在半导体材料中激发出新 的电子-空穴对。 这些被激发出来的空穴和电子在内建电场的作用 下分离， 并迅速在太阳能电池的上下两极积累。 基于上述原理， 将负载与太阳能电池两极相连， 即可实现太阳能电池为该负载供 电。
由于利用太阳能发电具有环保、 安全等优点， 因此， 在例如 液晶显示装置的耗电装置中， 尽可能有效地利用太阳能电池获取 光线来产生能量， 将极大地有利于节省资源的消耗以及保护环境。
常规的液晶显示装置包括： 驱动电路， 阵列基板， 彩膜基板， 设置在阵列基板与彩膜基板间的液晶层， 以及背光源。 其正常工 作时， 来自背光源的光透过阵列基板， 投射至液晶层； 驱动电路 通过调整阵列基板与彩膜基板之间的电场分布， 控制液晶层中液 晶分子发生转动， 使得由背光源发出的光部分或全部透过液晶层， 并经由彩膜基板透出， 从而实现显示。 公开号为 CN101813849A的中国专利申请中， 公开了这样一 种包含太阳能电池的显示器， 所述太阳能电池位于彩膜基板黑矩 阵的位置， 相当于把黑矩阵换成了太阳能电池， 从而将吸收到背 光源的光， 将光能转化成电能， 给液晶显示装置供电； 公开号为 CN101995691A 的中国专利申请中， 公开了一种包含太阳能电池 的显示器， 所述的太阳能电池位于显示器的非透光部件处， 同样 将吸收到背光源的光， 将光能转化成电能， 给液晶显示装置供电。 这两个专利只是分析液晶显示装置中非透光部件处的太阳能电 池， 而对于透光部件处的太阳能电池没有研究。 发明内容

为使本领域技术人员更好地理解本发明的技术方案， 下面结 合附图和具体实施方式对本发明作进一步详细描述。 如图 2至图 6所示， 本发明提供一种显示面板， 其包括由子 像素构成的透光区， 且至少在所述显示面板的部分透光区上设置 有太阳能电池 102, 用于给显示面板供电； 其中， 太阳能电池 102 的第一电极与第二电极均采用透明导电材料制成， 且至少与所述 透光区处的子像素颜色相同的光能够透过太阳能电池 102。 其中， 太阳能电池 102的第一电极和第二电极中的一个电极为阳极， 另 一电极为阴极， 透光区是指显示面板中光能够透过的任何地方。 本发明中的太阳能电池 102可以透过与透光区处的子像素颜 色相同的光， 同时太阳能电池 102也会吸收一定量的与子像素颜 色不相同的光， 将光能转化为电能， 为显示面板的驱动单元 （例 如栅极驱动单元、 源极驱动单元等）提供电能。 而且， 显示面板 的透光区的面积相对显示面板的遮光区的面积要大得多， 光照到 透光区的量比照到遮光区的量更多，由于本发明的太阳能电池 102 设置在显示面板的透光区， 因此与现有的太阳能电池设于非透光 部件处 （遮光区） 的结构相比较， 本发明的设于透光区的太阳能 电池 102 能够吸收到更多的光量， 光能转化的电能更多， 进而太 阳能电池 102的储能更多。
优选地， 太阳能电池 102包括第一电极、 第二电极以及第一 电极与第二电极之间的活性层， 所述活性层由 CdSe量子点组成。 本领域技术人员可以理解的是， 量子点的吸收特性和透过特性与 各种颜色的光的波长是相对应的， 并且量子点本身的吸收特性和 透过特性也是可以调节的， 与量子点本身的粒径相关。 当然， 本 发明的太阳能电池 102中的量子点不局限于 CdSe量子点一种，也 可以包括其他材料的量子点。
进一步优选地， 上述显示面板包括红色子像素、 绿色子像素 和蓝色子像素， 其中， 所述红色子像素所对应透光区上的太阳能 电池 102中 CdSe量子点的粒径在 15-20nm之间，此时太阳能电池 102可以吸收除红光以外的其他颜色的光，将光能转化为电能， 而 太阳能电池 102只透过红光； 所述绿色子像素所对应透光区上的 太阳能电池 102中 CdSe量子点的粒径在 8-13nm之间， 此时太阳 能电池 102 可以吸收除绿光以外的其他颜色的光， 将光能转化为 电能， 而太阳能电池 102只透过绿光； 所述蓝色子像素所对应透 光区上的太阳能电池 102中 CdSe量子点的粒径在 2-5nm之间，此 时太阳能电池 102可以吸收除蓝光以外的其他颜色的光， 将光能 转化为电能， 而太阳能电池 102只透过蓝光。 也就是说， 太阳能 电池 102 能透过与透光区处子像素颜色相同的光， 其他颜色的光 将被太阳能电池 102吸收， 因此， 太阳能电池 102不仅不会影响 各种颜色子像素的光的透过率， 同时还可以吸收未被利用的颜色 的光（与透光区处子像素颜色不同的光） ， 给显示面板的电源模 块等供电， 而不需要对锂电池进行充电， 给使用者带来方便。 同 理，对于包括其他量子点的太阳能电池 102, 可根据实际情况来设 置不同颜色子像素透光区处量子点的粒径， 以便透过与透光区处 子像素相同颜色的光。 实施例 1 :
