下面结合附图和较佳的实施例对本申请作进一步说明。
如图1至图4所示,本申请实施例公布了一种显示面板1。显示面板1包括:
第一基板2,第一基板2包括反射型偏光片6;
第二基板3,与第一基板2平行相向设置;
占空比电路4,设置在显示面板1内,调节反射型偏光片6对应的占空比阻隔紫外光;
第一基板2包括反射型偏光片6,占空比调节电路调节反射型偏光片6对应的占空比阻隔紫外光,第一基板2包括第一玻璃基板5,反射型偏光片6设在第一玻璃基板5内侧,反射型偏光片6在显示面板1内有且仅有一片,反射型偏光片6包括金属光栅9和狭缝8,金属光栅9设在偏光片上,金属光栅9之间形成狭缝8,反射型偏光片6包括多条狭缝8,透明层7设置在狭缝8内,狭缝8存在于反射型偏光片6外表面。
作为本申请的另一实施例,参考图2至图4所示,公布了一种显示面板1。显示面板1包括:

第一玻璃基板5;
反射型偏光片6设在第一玻璃基板5内侧。将反射型偏光片6制作于第一玻璃基板5内侧面可以防止反射型偏光片6被刮伤,擦伤等,其表面不需要单独贴保护膜。
本实施例可选的,反射型偏光片6在显示面板1内有且仅有一片。范例性的显示面板1的偏光片设于第一基板2和第二基板3内侧,显示屏的厚度会增加,反射型偏光片6只有一个,整体降低LCD的厚度。
本实施例可选的,反射型偏光片6包括金属光栅9和狭缝8,金属光栅9设在反射型偏光片上,金属光栅9之间形成狭缝8,反射型偏光片6包括多条狭缝8,透明层7设置在狭缝8内,狭缝8存在于反射型偏光片6外表面。
反射型偏光片6透光率高,紫外线透过多会使彩色电阻老化,破坏显示电路内部的其他材料,透明层7相当于钝化层21,通过调节金属光栅的占空比可以使得紫外线光透过率大大降低。
本实施例可选的,显示面板1包括:
金属光栅9设在反射型偏光片6上,金属光栅9之间形成狭缝8,反射型偏光片6包括多条狭缝8,透明层7设置在狭缝8内,狭缝8存在于反射型偏光片6外表面,显示面板包括液晶盒,第一基板还包括色阻层11,色阻层11设在透明层7,第二基板2包括第二玻璃基板23和 主动开关阵列13,液晶盒设于第一基板2和第二基板3之间,主动开关阵列13设于液晶盒12下方。
面板结构紧凑,LCD的厚度减小,透明层7填充在第一玻璃基板5和第一基板2的狭缝8中进行钝化,因为透明层7为透明材料,透明层7通过调节占空比就大大降低了紫外线的透光率,整个面板结构的紫外线的透过率就大大降低。
可选的,第一基板2的偏光片与第一玻璃基板5的形状相对应,第一基板2与第一玻璃基板5贴合。
偏光片与第一玻璃基板5的形状对应存在,这样就保证了显示的完整度,以及偏光的效果最佳,紫外线的防护面积最大,保证LCD使用的长久性。
可选的,占空比的区间为0.8~0.9。
TE和TM偏振方向的光具有不同的折射率,根据等效介质理论可知WGP(wire gratin polarizer)对TE和TM偏振光的折射率如下所示:
Figure PCTCN2018111308-appb-000001
Figure PCTCN2018111308-appb-000002
式中:n 1为狭缝中材料的折射率;n 3为金属线的折射率;f=W/P为光栅的占空比,W为金属线宽,P为条纹结构周期;n 2为光栅界面的等效折射率。
在不考虑吸收的情况下,WGP的透过率可以通过如下公式计算:
Figure PCTCN2018111308-appb-000003
由上可知当使用铝(但不仅限于铝)作线栅材料时,可以改变其占空比研究其对不同波长(部分波长)的透过率,结果如下所示:
Figure PCTCN2018111308-appb-000004
Figure PCTCN2018111308-appb-000005
如上表所示,当狭缝内为空气(n 1=1)时,TE和TM光的透过率随占空比f的增加而减小.考虑到工艺方面的问题,我们选择f=0.8和0.9进行计算可知,狭缝内填充材料的折射率越高,紫外线(UVA:280-380nm)的透过率随之降低(在牺牲可见光透过率的情况下),如下表所示:
Figure PCTCN2018111308-appb-000006
因此,狭缝8内填充材料的折射率越高,紫外线的透过率就会降低,可以通过调节反射型偏光片6的占空比和狭缝8材料的折射率来控制不同波长的光的(紫外线和可见光)的透过率,以满足液晶面板在不同条件下的使用。
本实施例可选的,占空比电路4设置在第二基板3上。
设于第二基板3上可以通过反射型偏光片6有足够的空间来调节透过光的波长,可以有一个缓冲的空间,易于更好的调节光透过率(紫外线和可见光)。
作为本申请的另一实施例,参考图5所示,公开了一种显示装置22。
一种显示装置22,包括以上实施例任意一项的显示面板1。
可以通过调节反射型偏光片6的占空比和狭缝8材料的折射率来控制不同波长的光的(紫外线和可见光)的透过率,以满足液晶面板在不同条件下的使用。
本申请的面板可以是TN面板(全称为Twisted Nematic,即扭曲向列型面板)、IPS面板(In-PaneSwitcing,平面转换)、VA面板(Multi-domain Vertica Aignment,多象限垂直配向技术),当然,也可以是其他类型的面板,适用即可。
以上内容是结合具体的优选实施方式对本申请所作的进一步详细说明,不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说,在不脱离本申请构思的前提下,还可以做出若干简单推演或替换,都应当视为属于本申请的保护范围。
