Description

一种高透光液晶屏
技术领域
本发明涉及一种液晶屏,特别涉及一种高透光液晶屏,本发明还涉及一种高透光液晶屏的制作方法。
背景技术
市场常见的液晶显示技术:首先把两片普能的钢化玻璃印刷上线路(透明的ITO材料),然后把两片的四周涂上框胶,再对它们对位压合好,接着在两边玻璃的中间灌注液晶,封住液晶口,然后在玻璃的上方和下方各贴一层偏光片。上层玻璃和下层玻璃所贴的偏光片不能同时过滤同一方向的光,例如:下层偏光片过滤的是X方向的光;那上层就必须是过滤Y方向的光,如果上下两层偏光片过滤的角度一样的话,就不能看到任何显示了,但是液晶还是在正常工作,只是肉眼没有办法看到而已。
液晶的物理特性是:当通电时导通,排列变的有秩序,使光线容易通过;不通电时排列混乱,阻止光线通过。让液晶如闸门般地阻隔或让光线穿透。从技术上简单地说,液晶面板包含了两片相当精致的无钠玻璃素材,称为Substrates,中间夹著一层液晶。当光束通过这层液晶时,液晶本身会排排站立或扭转呈不规则状,因而阻隔或使光束顺利通过。大多数液晶都属于有机复合物,由长棒状的分子构成。在自然状态下,这些棒状分子的长轴大致平行。将液晶倒入一个经精良加工的开槽平面,液晶分子会顺着槽排列,所以假如那些槽非常平行,则各分子也是完全平行的。
现在常用的液晶面板主要自带背光模组,液晶分子旋转角度不够理想,不能作为透明屏显示使用,如果作为透明显示会出现雾面模糊,透光度不够,画面暗淡等现象。
发明内容
本发明为克服现有技术的不足,提供一种透明液晶屏。
为达到上述目的,本发明采用如下的技术方案:
一种高透光液晶屏,依次包括上偏光片、第一液晶玻璃、第二液晶玻璃和下偏光片,所述第一液晶玻璃与第二液晶玻璃结合在一起,所述液晶玻璃上设置有逻辑板。
所述上偏光片和下偏光片为高透光偏光片,其透光率为47%。
一种上述高透光液晶屏的制作方法,包括如下步骤:
(1)取普通液晶显示屏,通电,测量普通液晶屏的电压和电流,得到普通液晶屏的工作电阻;
(2)不断调节普通液晶屏的电压,并测量普通液晶屏的透光率,当透光率达到最高时记录电压值,并根据记录下的电压值选择合适的电阻,更换合适的电阻在液晶逻辑板上;
(3)测量普通液晶屏的原上偏光片和原下偏光片的角度,撕掉原上偏光片和原下偏光片,选择合适角度的高透光偏光片,贴合于原有偏光片的位置,得到高透光液晶屏。
进一步的,所述高透偏光片的透光率为47%。
进一步的,所述合适角度为液晶分子排列方向完全垂直于液晶玻璃面板。
进一步的,所述高透光液晶屏的透光率为18-25%。
相对现有技术,本发明的有益效果为:
相对于传统液晶屏,本技术提高了液晶屏的透光率,由传统的4.6%提高至18%-25%,透光率大大增加,利用本高透的液晶屏,既能清晰的播放视频图画影音文件,又能看清楚液晶屏后面的物品,具有广泛的应用价值。
附图说明
图1为本发明一实施例所述的透明液晶屏的结构示意图。
附图标记
1-上偏光片;2-第一液晶玻璃;3-第二液晶玻璃;4-下偏光片;5-逻辑板。
具体实施方式
下面结合附图对本发明做进一步的详细说明,以令本领域技术人员参照说明书文字能够据以实施。
一种高透光液晶屏,依次包括上偏光片1、第一液晶玻璃2、第二液晶玻璃3和下偏光片4,所述第一液晶玻璃2与第二液晶玻璃3结合在一起,所述液晶玻璃(2、3)上设置有逻辑板5。
所述上偏光片1和下偏光片4为高透光偏光片,其透光率为47%。
所述逻辑板5为液晶玻璃上的控制电路。本发明在时将上偏光片1和下偏光片4采用高透光率的偏光片,在使用时适当调节加载在液晶屏的电压和电流使得本液晶屏透光率由传统的4.6%提高至18%-25%。
一种上述高透光液晶屏的制作方法,包括如下步骤:
(1)取普通液晶显示屏,通电,测量普通液晶屏的电压和电流,得到普通液晶屏的工作电阻;
(2)不断调节普通液晶屏的电压,并测量普通液晶屏的透光率,当透光率达到最高时记录电压值,并根据记录下的电压值选择合适的电阻,更换合适的电阻在液晶逻辑板上;
(3)测量普通液晶屏的原上偏光片和原下偏光片的角度,撕掉原上偏光片和原下偏光片,选择合适角度的高透光偏光片,该角度是液晶分子排列角度完全垂直于玻璃面板,以达到最高的透光率,贴合于原有偏光片的位置,得到高透光液晶屏。
所述高透偏光片的透光率为47%。
所述高透光液晶屏的透光率为18-25%。
本发明中普通液晶屏是在市场上可以买到的普通液晶屏,通过测试可知该普通液晶屏的透光度为4.6%,当应用于一些需要看到液晶屏后面物体时透光度不够。而本发明利用调节电压和电流,改变偏光片的方法将普通液晶屏的透光率提到至10-25%。
尽管本发明的实施方案已公开如上,但其并不仅仅限于说明书和实施方式中所列运用,它完全可以被适用于各种适合本发明的领域,对于熟悉本领域的人员而言,可容易地实现另外的修改,因此在不背离权利要求及等同范围所限定的一般概念下,本发明并不限于特定的细节和这里示出与描述的图例。
