 附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面对实施例中所需要使用的附图作简单的介绍。下面描述中的附图仅为本发明的部分实施例，对于本领域普通技术人员而言，在不付出创造性劳动的前提下，还可以根据这些附图获取其他的附图。
图1为本发明的液晶显示装置的优选实施例的结构示意图；
图2为本发明的液晶显示装置的优选实施例的石墨烯LED背光源的石墨烯LED芯片的结构示意图；
图3为本发明的液晶显示装置的优选实施例的石墨烯LED背光源的石墨烯LED芯片的具体结构示意图。
 本发明的最佳实施方式
请参照附图中的图式，其中相同的组件符号代表相同的组件。以下的说明是基于所例示的本发明具体实施例，其不应被视为限制本发明未在此详述的其它具体实施例。
请参照图1，图1为本发明的液晶显示装置的优选实施例的结构示意图。本优选实施例的液晶显示装置10包括石墨烯LED背光源11、第一偏光板12、第一基板13、液晶层14、第二基板15以及第二偏光板16。
石墨烯LED背光源11用于提供红色、绿色以及蓝色的背光源出射光；第一偏光板12用于将背光源出射光转换为背光源偏振光；第一基板13包括数据线、扫描线以及由数据线和扫描线构成的像素单元17，其中像素单元17包括像素电极；液晶层14包括用于对背光源偏振光进行偏转操作，以形成出射偏振光的液晶分子；第二基板15包括用于与像素电极配合驱动液晶分子的公共电极；第二偏光板16用于将相应的出射偏振光射出。该液晶层14优选为包括蓝相液晶分子的蓝相液晶层，该蓝相液晶分子的响应时间在亚毫秒数量级，因此可较好的与切换频率较高的石墨烯LED背光源11进行配合。
其中石墨烯LED背光源11包括多个石墨烯LED芯片20，请参照图2和图3，图2为本发明的液晶显示装置的优选实施例的石墨烯LED背光源的石墨烯LED芯片的结构示意图；图3为本发明的液晶显示装置的优选实施例的石墨烯LED背光源的石墨烯LED芯片的具体结构示意图。
该石墨烯LED芯片20包括阳极端21、阴极端22、控制端23以及发光层24。阳极端21用于与电源正极（图中未示出）连接；阴极端22用于与电源负极（图中未示出）连接；控制端23用于输入控制电压，其中控制电压用于控制背光源出射光的波长；发光层24用于根据控制电压以及电源电压，发出背光源出射光。发光层24位于阳极端21、阴极端22以及控制端23之间。
其中阳极端21和阴极端22应为导电优良的材料制成，阳极端21的材料包括但不限于聚乙撑二氧噻吩（PEDOT）、碳纳米管（CNT）、聚乙撑二氧噻吩以及混合碳纳米管中至少一种；阴极端22的材料包括但不限于聚乙撑二氧噻吩、聚吡咯；碳纳米管、聚乙撑二氧噻吩以及混合碳纳米管中至少一种；控制端23的材料为氧化石墨烯；发光层24的材料为还原石墨烯。
其中PEDOT中存在π-π*键共轭结构，有助于电子注入到还原石墨烯的发光层中；CNT是由六元环碳构成的类石墨平面卷曲而成的纳米级中空管，其具有较好的导电性、较高的热稳定性和本征迁移率，也是理想的电极材料。
本优选实施例的液晶显示装置10的画面帧包括红色画面帧、蓝色画面帧以及绿色画面帧。这样本优选实施例的液晶显示装置使用时，将石墨烯LED背光源11进行分时控制，即将一个画面帧的显示时间分为三个子画面帧的显示时间，这三个子画面帧的显示时间内分别液晶显示装置10分别显示红色画面帧、蓝色画面帧以及绿色画面帧。
当液晶显示装置10处于红色画面帧时，石墨烯LED背光源11提供红色的背光源出射光（这时控制信号的电压可为0V，背光源出射光的波长为680nm），且数据线提供相应的红色画面帧的数据信号。当液晶显示装置10处于绿色画面帧时，石墨烯LED背光源11提供绿色的背光源出射光（这时控制信号的电压为30V，背光源出射光的波长为550nm），且数据线提供相应的绿色画面帧的数据信号。当液晶显示装置10处于蓝色画面帧时，石墨烯LED背光源11提供蓝色的背光源出射光（这时控制信号的电压为50V，背光源出射光的波长为470nm），且数据线提供相应的蓝色画面帧的数据信号。这里红色画面帧的显示时间、蓝色画面帧的显示时间以及绿色画面帧的显示时间均相等，以保证显示画面的稳定性。
本优选实施例的液晶显示装置10显示一个画面帧时，可在第一个三分之一帧的时间内，发送该画面帧的红色画面帧至像素单元17，且石墨烯LED背光源11提供红色的背光源出射光；在第二个三分之一帧的时间内，发送画面帧的绿色画面帧至像素单元17，且石墨烯LED背光源11提供绿色的背光源出射光；在第三个三分之一帧的时间内，发送画面帧的蓝色画面帧至像素单元17，且石墨烯LED背光源11提供蓝色的背光源出射光。这样在一帧画面内，根据人眼视觉残留效应，该画面帧对应的红色画面帧、蓝色画面帧以及绿色画面帧在人眼中形成画面帧对应的显示画面，即三种不同颜色的光可以形成混色效果，从而形成彩色的显示画面。
这样即完成了本优选实施例的液晶显示装置10的画面显示过程。
因此本发明的液晶显示装置通过石墨烯LED背光源的设置，使得背光源可直接发出红色、绿色以及蓝色出射光，因此不需要在第二基板上设置任何色阻，因此液晶显示装置的画面分辨率较高且制作成本较低；解决了现有的液晶显示装置的画面分辨率较低且制作成本较高的技术问题。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
