Description

液晶面板及液晶显示器 技术领域
本发明涉及一种液晶面板及液晶显示器。 背景技术
液晶显示器是一种超薄的显示设备， 它包括彼此相对设置的两块基板， 两基板之间设置有液晶。液晶显示器功耗较低，适用于使用电池的电子设备， 因此倍受青睐。
随着技术的发展， 人们对液晶显示器的要求也变得多样化， 对手机等小 型显示器的附属功能的需求也越来越多。 发明人发现， 现有技术中还没有带 有镜子功能的手机显示器。 发明内容
根据本发明的一个实施例提供一种液晶面板， 包括： 彼此相对设置的上 基板和下基板， 两基板上分别设有透明电极层； 以及负性胆甾相液晶层， 设 置于所述上基板和所述下基板之间， 且所述负性胆 <甾相液晶层中添加有手性 离子液体， 其中所述上基板和所述下基板上的所述透明电极层与交流电源连 接。
根据本发明的另一个实施例提供一种液晶显示器， 包括根据本发明任一 实施例的液晶面板。 附图说明
为了更清楚地说明本发明实施例的技术方案， 下面将对实施例的附图作 简单地介绍，显而易见地，下面描述中的附图仅仅涉及本发明的一些实施例， 而非对本发明的限制。
图 1表示本发明实施例提供的液晶面板结构图；
图 2表示本发明实施例提供的液晶原始状态下的液晶织构示意图； 图 3表示本发明实施例提供的液晶焦锥织构示意图； 图 4表示本发明实施例提供的液晶平面织构示意图；
图 5表示本发明实施例提供的反射型液晶面板结构图； 以及
图 6表示本发明实施例提供的增加光源的反射型液晶面板结构图。 具体实施方式
为使本发明实施例的目的、 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，对本发明实施例的技术方案进行清楚、 完整地描述。显然， 所描述的实施例是本发明的一部分实施例， 而不是全部的实施例。 基于所描 述的本发明的实施例， 本领域普通技术人员在无需创造性劳动的前提下所获 得的所有其他实施例， 都属于本发明保护的范围。
本发明实施例在负性胆甾相液晶 6中加入手性离子液体 5 , 通过电场控 制手性离子液体 5的移动以及胆甾相液晶的织构变化， 从而实现电场控制的 透射、 散射、 镜面反射三态， 以此实现镜子的效果。
手性离子液体是兼具手性材料和离子液体材料的双重功能。 本发明实施 例中釆用的手性离子液体没有特别的限制， 它可以是由阳离子组成的， 也可 以是由阴离子组成的。 只需要在指定的温度范围（例如， -20摄氏度〜 80摄氏 度） 内保持液体状态， 且具有与液晶艮好的相容性以及良好的导电性即可。
如图 1所示， 本发明第一实施例提供的液晶面板， 包括上基板 1、 下基 板 2, 两基板上分别设有透明电极层 3 ,上下基板之间设置有加入手性离子液 体 5的负性胆甾相液晶 6。 两透明电极层 3与具有可控制开关状态的、 能够 使负性胆甾相液晶呈反射态的交流电源 4连接。 为了能够实现正常的液晶面 板的显示功能， 两透明电极层还与能够实现正常显示的交流信号连接， 一般 釆用较低频率（100至 200赫兹） 的交流信号。 也就是说， 在正常显示时， 两透明电极层与频率在 100至 200赫兹的交流信号连接； 在不需要显示时而 需要实现镜子功能时， 两透明电极层与具有可控开关状态的、 能够使加入手 性离子液体的负性胆甾相液晶呈反射态的交流电源 4连接 (一般釆用频率大 于 8000赫兹的交流信号） ， 通过此方式来实现镜子的功能。
例如， 用于驱动根据本发明实施例的液晶面板的交流电源可以输出低频 交流信号和高频交流信号， 并且能够在这两种信号下切换。 例如， 低频交流 信号具有 100赫兹至 200赫兹的频率，高频交流信号具有 8000赫兹以上的频 率。 因此， 在这种交流电源控制下， 根据本发明的液晶显示面板可以在低频 信号作用下进行正常显示， 而在高频交流信号作用下呈现反射功能。 所述交 流电源的具体形式并没有特别限制。
由于釆用加入手性离子液体 5的负性胆甾相液晶 6, 同时使液晶面板中 的透明导电层与具有可控开关状态的、 能够使加入手性离子液体的负性胆甾 向液晶呈反射态的交流电源， 在较低频率（ 100赫兹至 200赫兹） 的交流电 源的作用下实现正常的图像显示， 在较高频率（8000赫兹以上）的交流电源 的作用下， 手性离子液体 5的分布集中在电极侧， 出现负性胆甾相液晶 6的 螺距梯度分布， 从而显示镜面反射状态， 实现镜子的效果。
当然为了能够较快的呈现镜面反射状态， 还可以将透明电极层与直流电 源连接， 通过增加直流电源使得液晶面板成透射、 散射、 镜面反射三态的变 化。在这种情况下，液晶分子的反应速度比从透射态直接到镜面反射态更快。
加入手性离子液体 5的负性胆甾相液晶 6在不加电的情况下的原始状态 如图 2所示， 呈现透射态。在直流电场作用下， 手性离子液体 5向电极迁移， 而负性胆甾相液晶呈现焦锥织构， 如图 3所示， 呈现散射态。 散射状态后切 换至高频率（ 8000赫兹以上）的交流电压， 负性胆 <甾相液晶 6从焦锥织构转 换至如图 4所示平面织构。 由于手性离子液体 5的分布集中在电极侧， 出现 负性胆甾相液晶 6的螺距梯度分布， 而显示镜面反射状态。 撤去高频率电压 以后， 恢复如图 2的原始状态， 显示透射状态。 同时， 所加电压的大小不同， 手性离子液体 5的扩散程度不同， 从而反射波宽也不同， 透过率也不同。 通 过调节施加电压的大小， 可以调节负性胆<甾相液晶 6的透过率， 光线再经过 彩膜， 从而显示出任何颜色。
本发明实施例釆用加入手性离子液体 5的负性胆甾相液晶 6在上基板 1 和下基板 2中间， 而加入手性离子液体 5的负性胆甾相液晶 6在镜面反射状 态时， 可实现镜子的效果。 同时由于釆用胆甾相液晶， 不需要设置偏光片， 因此可大大提高光的有效率。
本发明实施例液晶显示器中的液晶面板可以^^射型液晶面板。 由于小 型反射型液晶显示器在室外室内都会常被使用， 所以只靠环境光来显示是不 够的。 考虑到上述情况， 可以通过在反射型液晶显示器中设置光源， 这样即 使在黑暗环境下也可以显示。 作为反射型液晶显示器， 光源不能设置在后面 的下基板 2上， 一般反射型液晶显示器在上基板 1侧面设置光源。
图 5为本发明实施例的反射型液晶显示器的液晶面板示意图。 如图 5所 示， 反射型液晶面板具有彼此相对设置的上基板 1和下基板 2, 且两基板上 分别设有透明电极层 3 , 透明电极层 3与交流电源 4连接。 在下基板 2靠近 液晶一侧设置反射板 7,反射板 7上设置有彩膜 8,透明电极层 3设置在彩膜 8上。 在两基板间有加入手性离子液体 5的负性胆甾相液晶 6。 在低频（100 至 200赫兹） 交流信号下， 液晶面板能够实现正常的显示功能； 在施加直流 信号时， 液晶层是焦锥织构的散射态， 因此显示暗态； 在施加高频率交流信 号（大于 8000Hz )时， 液晶层是带有不同螺距分布的平面织构， 而实现镜子 效果。
图 6为增加光源的反射型液晶显示器的的液晶面板示意图， 在前述方案 的基础上再加设光源及导光板。 具体而言， 上基板 1上设置有光源 9以及与 光源 9配合的导光板 10, 光源 9设置在上基板 1的侧面。 例如， 导光板 10 可以设置在上基板 1的上侧。 在明亮环境下， 光源是关闭状态， 而利用环境 光来显示。 在黑暗环境下， 光源是开启状态， 从光源发出的光通过导光板而 到液晶层， 再经过彩膜和反射层从而实现显示功能。
本发明第二实施例提供一种液晶显示器， 包括有如前述的液晶面板。 该 液晶显示器包括如上所述的交流电源。 或者， 该液晶显示器还进一步包括如 上所述的直流电源， 这里不再赘述。
由于釆用加入手性离子液体的负性胆甾相液晶， 同时使液晶面板中的透 明导电层与具有可控开关状态的、 能够使加入手性离子液体的负性胆甾向液 晶呈反射态的交流电源， 当需要正常显示时， 液晶面板与能够实现正常显示 的交流信号连接； 在需要液晶面板实现镜子功能时， 将信号切换至具有可控 开关状态的、 能够使加入手性离子液体的负性胆甾向液晶呈反射态的交流电 源。 从而在液晶面板中增加了镜子的功能。
