Description

一种电容触控液晶显示面板及其显示装置 技术领域
本发明涉及显示技术领域,具体涉及一种电容触控液晶显示面板及其显示装置。
背景技术
液晶是一种介于固体和液体之间的特殊物质,它是一种有机化合物,常态下呈液态,但是它的分子排列却和固体晶体一样非常规则,因此取名液晶。液晶的另一个特殊性质在于,在不施加电场时,光线可以顺利透过;在给液晶施加一个电场的情况下,会改变它的分子排列,这时如果给它配合偏振光片,它就具有阻止光线通过的作用,如果再配合彩色滤光片,改变加给液晶电压大小,就能改变某一颜色透光量的多少,也可以形象地说改变液晶两端的电压就能改变它的透光度。
液晶显示器(英文全称:Liquid Crystal Display,简称LCD)的工作原理是将液晶置于两片导电玻璃之间,靠两个电极间电场的驱动,引起液晶分子扭曲向列的电场效应,以控制光源透射或遮蔽功能,在电源关开之间产生明暗变化,从而将影像显示出来。若加上彩色滤光片,则可显示彩色影像。在两片玻璃基板上装有配向膜,所以液晶会沿着沟槽配向,由于玻璃基板配向膜沟槽偏离90度,所以液晶分子成为扭转型,当玻璃基板没有加入电场时,光线透过偏光板跟着液晶做90度扭转,通过下方偏光板,液晶面板显示白色;当玻璃基板加入电场时,液晶分子产生配列变化,光线通过液晶分子空隙维持原方向,被下方偏光板遮蔽,光线被吸收无法透出,液晶面板显示黑色。液晶显示器便是根据此电压有无,使面板达到显示效果。
在日常生活中,我们经常会接触到各种类型的触摸屏幕,从个人消费端的手机、平板,到生活和工作的电脑,再到家用的电视机,以及各种应用场景的商用显示屏等。一般的触摸屏幕包含两个部分:触摸检测装置和触摸控制器。触摸检测装置是安装在显示器屏幕前面,用于检测用户触摸位置,并把接收到信息传送到触摸屏控制器;触摸屏控制器的主要作用是从触摸点检测装置上接收触摸信息,并将它转换成触点坐标,再传送给CPU,它同时能接收到CPU发来的命令并加以执行。目前的触控一体机都是红外式的,比如导航机和图书阅览机等,而电磁触摸屏的代表性产品是电子阅读器,电容触摸屏的代表性产品则是智能手机。
红外触控屏是利用 X 、 Y 方向上密布的红外线矩阵来检测并定位用户的触摸。红外触控屏在显示器的前面安装一个电路板外框,电路板在屏幕四边排布红外发射管和红外接收管,一一对应形成横竖交叉的红外线矩阵。由于价格原因,当前主流的触控技术为红外技术,但触控体验较差。
电磁式触摸屏的基本原理是依靠电磁笔和感应器在操作过程中产生的磁场变化来进行判别,电磁笔为讯号发射端(transceiver),天线板为讯号接收端(receiver),当接近感应时磁通量发生变化,继而由运算定义位置点。电磁式触摸屏成本较高,透光率和解析度高,拥有Z轴感应能力,反应灵敏,无需触碰即可触控,适合用来绘图和手写辨识等等。
电容式触摸屏成本较高,其原理是利用生特和屏幕接触时产生的电流来定位,所以可以用手指头来操作,但非生物体,像指甲、笔都无法操作。电容触摸屏的双玻璃不但能够保护导体和感应器,更能在即使屏幕沾有污秽、尘埃或油渍,电容式触摸屏依然能精准地计算出触摸位置。
技术问题
因此,目前电容触控以其相对灵敏的触控体现,受到越来越多的用户使用和接受。但目前大尺寸边框的电容触控屏采用膜片类型的触控传感器,传感器需要在外围设计信号走线,由于现有制程的限制,其外形尺寸要比液晶面板大,这就对触控屏和液晶面板的包装和机构设计提出了新的诉求。因此需要寻求一种新型的电容触控液晶显示面板以解决上述问题。

如图1所示,本发明的电容触控液晶显示面板1000,其中包括液晶面板100和电容触控传感膜200。其中所述电容触控传感膜200通过光学胶300连接于所述液晶面板100上。
其中所述液晶面板100包括依次设置的下偏光片101、TFT基板102、液晶层103、彩膜基板104以及上偏光片105。
其中所述下偏光片101的基本结构包括:最中间的PVA(聚乙烯醇),两层TAC(三醋酸纤维素),PSA film(压敏胶),Release film(离型膜) 和Protective film(保护膜)。其中PVA膜是一种高分子聚合物,用各类具有二向色性的有机染料进行染色,同时在一定的湿度和温度条件下进行延伸,使其吸收二向色性染料形成偏振性能,在脱水、烘干后形成偏光片原膜;由于PVA膜具有亲水性,在湿热的环境中很快就会变形、收缩、松弛、衰退、且强度很低,质脆易破,不便于实用和加工,因此需要在膜两边都复合上一层强度高、透光率高而又耐湿热的TAC膜,由此形成了偏光片原板。偏光片的作用是使自然光变成线偏振光。
其中所述TFT基板102(英文全称:thin film transistor,薄膜晶体管)的作用是用来主动控制每一个像素的器件,这样就相当于在每一个像素点上设计了一个场效应开关管,多个TFT构成TFT基102。
其中所述彩膜基板104(英文全称:Color filter,简称CF)基本结构是由玻璃基板(Glass Substrate),黑色矩阵(Black Matrix),彩色层(Color Layer),保护层(Over Coat),ITO导电膜组成。彩膜基板104是一种表现颜色的光学滤光片,它可以精确选择欲通过的小范围波段光波,而反射掉其他不希望通过的波段。
其中所述上偏光片105的基本结构与下偏光片101的基本结构一致。为实现液晶片能够显示图像,需要上偏光片105和下偏光片101共同存在。
其中所述光学胶300是用于胶结透明液晶显示面板中的光学元件的特种胶粘剂。
其中所述电容触控传感膜200包括依次设置的PET基层201、导电层202以及保护层203。其中所述导电层202设置于所述PET基层201上,所述保护层203设置于所述导电层202上,其中所述PET基层201与所述导电层202之间以及所述导电层202与所述保护层203之间均通过光学胶300连接。其中所述电容触控传感膜200的组成成分包括氧化铟锡和/或纳米银,由此制成的电容触控传感膜200具有一定的柔韧性。
如图2所示,导电层202上包括走线区和非走线区,所述走线区设有水平信号线2021和竖直信号线2022,所述电容触控传感膜200的非走线区由上至下贯穿所述电容触控传感膜200直至所述液晶面板100设有至少一个缺口2023,所述缺口2023可以包括2个数量,两个缺口2023可以对角设置,也可以设置在所述触控传感膜200的一侧;所述缺口2023还可以包括3个数量,三个缺口2023可以等腰设置,具体可随需要而定,并无限定。本实施例优选的所述非走线区设有四个缺口2023;所述缺口2023分别设置于所述电容触控传感膜200的四个角上;所述设置缺口后的电容触控传感膜对应于所述液晶面板的投影面积小于所述液晶面板的面积。本实施例中的所述缺口2023与所述电容触控传感膜200的两个接触面之间的夹角形状为直角。其中缺口的数量根据非走线区的实际情况确定。其中所述缺口2023通过激光切割的方式制备而成。由于触控传感膜200是柔软的,无法进行定位设计,但是液晶面板100具有一定的硬度,由此本发明将所述液晶面板100的局部暴露出来,利用局部露出的玻璃材质的液晶面板100边缘进行定位设计,满足电容触控传感膜200和液晶面板100的包装和定位设计,最终降低生产成本。
实施例2
以下仅就本实施例与实施例1之间的相异之处进行说明,而其相同之处则在此不再赘述。
如图3所示,本实施例中的所述缺口2023与所述电容触控传感膜200的两个接触面之间的夹角形状为倒角。其中所述缺口2023通过激光切割的方式制备而成。由于触控传感膜200是柔软的,无法进行定位设计,但是液晶面板100具有一定的硬度,由此本发明将所述液晶面板100的局部暴露出来,利用局部露出的玻璃材质的液晶面板100边缘进行定位设计,满足电容触控传感膜200和液晶面板100的包装和定位设计,最终降低生产成本。
实施例3
以下仅就本实施例与实施例1之间的相异之处进行说明,而其相同之处则在此不再赘述。
如图4所示,本实施例中的所述缺口2023与所述电容触控传感膜200的两个接触面之间的夹角形状为圆角。其中所述缺口2023通过激光切割的方式制备而成。由于触控传感膜200是柔软的,无法进行定位设计,但是液晶面板100具有一定的硬度,由此本发明将所述液晶面板100的局部暴露出来,利用局部露出的玻璃材质的液晶面板100边缘进行定位设计,满足电容触控传感膜200和液晶面板100的包装和定位设计,最终降低生产成本。
实施例4
