Description

反射式液晶显示面板 技术领域
本发明涉及液晶显示技术领域，特别涉及一种反射式液晶显示面板。
 背景技术
随着穿戴式设备如智能手表、智能眼镜等产品和应用的逐渐兴起，在电池电量一定的情况下，显示器的能耗问题将极大影响产品整体的续航能力，所以开发出低能耗且性能优越的显示器变得越来越重要。
其中反射式液晶显示面板在穿戴设备应用中具有较大的潜力。反射式液晶显示面板，可如纸张一样反射环境光线用来显示内容，无需耗能极高的背光源，与传统的主动式液晶显示面板相比，可节省80%以上能量损耗，由此可极大延长设备电池的续航时间，改善用户体验。
请参照图1，图1为现有的反射式液晶显示面板的结构示意图。其中11为上基板衬底，12为彩膜色阻，13为公共电极，14为液晶层，15为金属反射电极，16为下基板衬底。其中彩膜色阻12包含了RGB三种不同颜色的色阻。不同颜色的色阻具有不同的透过频谱，红色色阻可使红色波长范围的光线透过，吸收非红色波长范围的光线；蓝色色阻可使蓝色波长范围的光线通过，吸收非蓝色波长范围的光线；绿色色阻可使绿色波长范围的光线通过，吸收非绿色波长范围的光线。
现有的反射式液晶显示面板使用时，由于反射式液晶显示面板是对外界环境光进行反射，因此外界环境光通过彩膜色阻12进入到液晶层14之后，通过金属反射电极15的反射会再次通过彩膜色阻12射出。外界光线需要穿过两次彩膜色阻12，光线需要被同一彩膜色阻或者不同的彩膜色阻吸收两次，因此导致反射式液晶显示面板容易出现光反射率较低且画面混色不良的问题。
故，有必要提供一种反射式液晶显示面板，以解决现有技术所存在的问题。

 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为现有的反射式液晶显示面板的结构示意图；
图2为本发明的反射式液晶显示面板的第一优选实施例的结构示意图；
图3为本发明的反射式液晶显示面板的第二优选实施例的结构示意图。
 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2，图2为本发明的反射式液晶显示面板的第一优选实施例的结构示意图。本优选实施例的反射式液晶显示面板20包括上基板、下基板以及设置在上基板和下基板之间的液晶层23。
上基板包括上基板衬底21以及公共电极22，该公共电极22设置在上基板衬底21内侧，用于提供公共电压，该公共电极22为透明金属电极，如氧化铟锡（ITO）等。
下基板包括下基板衬底26、像素电极25以及彩色反射层24，像素电极25设置在下基板衬底26内侧，用于提供驱动电压；彩色反射层24设置在像素电极25上，用于反射外界环境光线。
其中彩色反射层24为非透明的具有选择波长反射特性的高反射率层。具体彩色反射层24包括红色反射层、蓝色反射层以及绿色反射层，红色反射层具有较高的红光波长的反射率，蓝色反射层具有较高的蓝光波长的反射率，绿色反射层具有较高的绿色波长的反射率。不同颜色的彩色反射层24之间还设置有黑色矩阵（图中未示出），用于吸收全波段的光线，以避免在单色像素的边缘发生串扰现象。
其中像素电极25可为透明金属电极或非透明的金属电极，由于这里采用彩色反射层24的反射光线作为光源，因此设置在彩色反射层24下方的像素电极25可为非透明的金属电极，以降低像素电极25的制作成本。当然这里也可根据用户需求采用透明金属电极，如氧化铟锡（ITO）等。
本优选实施例的反射式液晶显示面板20使用时，通过驱动电路给像素电极25施加驱动电压，给公共电极22施加公共电压，液晶层23中的液晶分子在驱动电压和公共电压的作用下发生偏转，使得液晶层23开始透过线偏振光。因此外界环境光依次通过上基板衬底21、公共电极22、液晶层23到达彩色反射层24，在彩色反射层24发生反射。
由于红色反射层只反射红光、蓝色反射层只反射蓝光、绿色反射层只反射滤光，因此外界环境光进行彩色发射层反射后形成红蓝绿三种出射光，三种出射光依次通过液晶层23、公共电极22以及上基板衬底21后出射。这样即完成了红绿蓝像素单元的画面显示过程。
由于本优选实施例的反射式液晶显示面板20的画面显示过程没有在上基板上设置彩膜色阻，因此外界环境光不会被彩膜色阻吸收两次，只需要被彩色发射层24进行一次吸收反射即可，因此该反射式液晶显示面板20的光反射率较高且不易出现画面混色不良。
优选的，本优选实施例的反射式液晶显示面板20的上基板或下基板的内侧表面还设置有间隔子（PS，photo spacer）（图中未示出），以便保持上基板和下基板之间的液晶层23的厚度。
本优选实施例的反射式液晶显示面板通过在下基板上设置彩色反射层，使得外界环境光只需要通过彩色反射层反射一次即可出射，减小了外界环境光在彩膜色阻上的损耗，提高了反射式液晶显示面板的光反射率且提高了反射式液晶显示面板的彩色画面显示效果。
请参照图3，图3为本发明的反射式液晶显示面板的第二优选实施例的结构示意图。本优选实施例的反射式液晶显示面板30包括上基板、下基板以及设置在上基板和下基板之间的液晶层33。
上基板包括上基板衬底31以及公共电极32，该公共电极32用于提供公共电压，该公共电极32为透明金属电极，如氧化铟锡（ITO）等。
下基板包括下基板衬底36、像素电极35以及彩色反射层34，彩色反射层34设置在下基板衬底36内侧，用于反射外界环境光线，像素电极35设置在彩色反射层34上，用于提供驱动电压。
其中彩色反射层34为非透明的具有选择波长反射特性的高反射率层。具体彩色反射层34包括红色反射层、蓝色反射层以及绿色反射层，红色反射层具有较高的红光波长的反射率，蓝色反射层具有较高的蓝光波长的反射率，绿色反射层具有较高的绿色波长的反射率。不同颜色的反射层之间还设置有黑色矩阵（图中未示出），用于吸收全波段的光线，以避免在单色像素的边缘发生串扰现象。
其中像素电极35可为透明金属电极，如氧化铟锡（ITO）等。像素电极35设置在彩色反射层34之上，有利于降低电极间距，提高液晶电容，降低驱动电压。
本优选实施例的反射式液晶显示面板30使用时，通过驱动电路给像素电极35施加驱动电压，给公共电极32施加公共电压，液晶层33中的液晶分子在驱动电压和公共电压的作用下发生偏转，使得液晶层33开始透过线偏振光。因此外界环境光依次通过上基板衬底31、公共电极32、液晶层33以及像素电极35到达彩色反射层34，在彩色反射层34发生反射。
由于红色反射层只反射红光、蓝色反射层只反射蓝光、绿色反射层只反射滤光，因此外界环境光进行彩色发射层反射后形成红蓝绿三种出射光，三种出射光依次通过像素电极35、液晶层33、公共电极32以及上基板衬底31后出射。这样即完成了红绿蓝像素单元的画面显示过程。
由于本优选实施例的反射式液晶显示面板30的画面显示过程没有在上基板上设置彩膜色阻，因此外界环境光不需要被彩膜色阻吸收两次，只需要被彩色发射层34进行一次吸收反射即可，因此该反射式液晶显示面板30的光反射率较高且不易出现画面混色不良。
优选的，本优选实施例的反射式液晶显示面板30的上基板或下基板的内侧表面还设置有间隔子，以便保持上基板和下基板之间的液晶层的厚度。
在第一优选实施例的基础上，本优选实施例的反射式液晶显示面板的像素电极设置在彩色反射层之上，有利于降低电极间距，提高液晶电容，降低驱动电压；进一步提高了画面显示质量。
本发明的反射式液晶显示面板通过在下基板上设置彩色反射层，使得外界环境光只需要通过彩色反射层反射一次即可出射，减小了外界环境光在彩膜色阻上的损耗，提高了反射式液晶显示面板的光反射率且提高了反射式液晶显示面板的彩色画面显示效果；解决了现有的反射式液晶显示面板容易出现光反射率较低且画面混色不良的技术问题。
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。
