技术领域

背景技术
现有技术中公开号为“CN102129140B”的一种液晶显示装置的制造方法,能够通过喷墨法涂布小型且窄边框的液晶显示装置中的取向膜,在包括具有像素电极的显示区域和其周边区域的TFT基板上,用喷墨法将干燥迅速的周边取向膜涂布成框状,之后,用喷墨法涂布干燥缓慢但均化效果优异的显示区域取向膜,显示区域取向膜干燥缓慢,但由于形成于周边的周边取向膜成为限制器,所以能够准确地限定取向膜的外形,由此,能够防止密封材料的粘合力因取向膜的影响而降低,对置基板侧也相同。
上述液晶显示装置的制造方法所生产出的TFT液晶显示装置即为现有技术中常见的TFT显示模组,但是上述该TFT显示模组在使用过程中仍然存在较为明显的缺陷:上述装置及现有的TFT显示模组,其光线透过第二偏光片后垂直穿过基板表面,由于相邻液晶显色单元的光线出射位置存在差异,从而导致基板的各个显色区域出射光线之间存在一定的显色干扰可能,进而导致局部色彩失真或对比度大等问题,影响TFT显示模组的显色效果。
发明内容
本发明的目的在于提供TFT液晶显示器件及其制作方法,以解决上述背景技术中提出的问题。
为实现上述目的,本发明提供如下技术方案:

彩色滤光膜,偏转后的光线透过阵列排布的所述彩色滤光膜后被赋予相应颜色,所述彩色滤光膜包括红、绿、蓝三色的像素点;
第二偏光片,所述第二偏光片上设置的后端进光格栅与前端进光格栅相互垂直,所述后端进光格栅与红、绿、蓝三色像素点一一对应设置;
光线折射膜,所述光线折射膜上设置有将后端进光格栅入射的光线进行偏转的偏转区;以及
基板,所述基板上设置有与若干组彩色滤光膜一一对应的显示区,经偏转区折射转向的光线投射至所述显示区的中心位置。
优选的,所述背光模组包括背光板和LCD光源,所述LCD光源包括但不限于底部平铺式设置或侧边式设置,所述背光板设置于LCD光源光线照射方向的背侧。
优选的,所述LCD光源为点阵式设置的发光二极管。
优选的,所述背光模组和第一偏光片之间设置有导光板,所述导光板的光线出射路径处开设有点阵式设置的光线扩散膜孔。
优选的,所述液晶层前后电极层之间区域还设置有配向膜,前后两侧的所述配向膜上开设有相互垂直的配向槽。
一种TFT液晶显示器件的制作方法,采用上述的TFT液晶显示器件,将所述背光模组、导光板、第一偏光片、电极层、配向膜、液晶层、彩色滤光膜、第二偏光片、基板按照贴合顺序依次通过光学胶进行叠加贴合即可。
与现有技术相比,本发明的有益效果是:
本发明通过在第二偏光片的后端进光格栅内设置有对光线进行折射变向的偏转区,使得光线在穿过第二偏光片后汇聚于基板显示区的中心区域,有效克服了相邻显色单元之间的出射光线间距不一致的现象,统一了相邻显色单元出射光线之间的距离,解决了TFT显示模组局部色彩失真或对比度不协调等问题,进一步提高了TFT显示模组的显色性能。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动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。
请参阅图1-4,本发明提供一种技术方案:
实施例一:
TFT液晶显示器件,包括:
背光模组,背光模组内设有产生光线的光源;
第一偏光片1,第一偏光片1上设置有供特定方向光线穿透的前端进光格栅2;
液晶层3,液晶层3内阵列式排布有液晶分子4,液晶层3位于光线入射的前后两端设置有电极层5,电极层5通过产生的电场使液晶分子4变向进而改变从第一偏光片1入射光线的偏转方向;
彩色滤光膜6,偏转后的光线透过阵列排布的彩色滤光膜6后被赋予相应颜色,彩色滤光膜6包括红、绿、蓝三色的像素点;
第二偏光片7,第二偏光片7上设置的后端进光格栅8与前端进光格栅2相互垂直,后端进光格栅8与红、绿、蓝三色像素点一一对应设置;
光线折射膜18,光线折射膜18上设置有将后端进光格栅8入射的光线进行偏转的偏转区9;以及
基板11,基板11上设置有与若干组彩色滤光膜6一一对应的显示区12,经偏转区9折射转向的光线投射至显示区12的中心位置。
在该实施例中,背光模组用于产生光源,光源通过第一偏光片1设置的前端进光格栅2进入液晶层3内,液晶层3内部的液晶分子4在电极层5产生的电场作用下发生偏转从而改变从第一偏光片1入射光线的偏转方向,光线穿过液晶层3后达到彩色滤光膜6被赋予相应颜色,随后光线达到第二偏光片7,由于第二偏光片7设置的后端进光格栅8与前端进光格栅2相互垂直,因此未经液晶分子4偏转的光线无法穿过第二偏光片7,上述原理为TFT显示模组的常用显色方式,在此不再进行赘述,而与现有技术不同的是,本发明的第二偏光片7后端增设了光线折射膜18层结构,光线折射膜18用于将后端进光格栅8入射的光线进行偏转的偏转区9,参照说明书附图4可知,现有技术中穿过第二偏光片7的光线垂直式穿过基板11表面,由于光线垂直式射出,因此光线射出位置在基板11表面处于不确定性,当相邻显色模块出射光线距离较近,就会发生显色干扰现象,从而影响TFT显示模组的显色效果,因此本申请设置光线折射膜18的目的在于将不同出射光线向基板11上显示区12的中心位置进行投射,进而不同显色模块之间即使出射光距离较近也不会发生显色干扰现场,有效保证了各个显色单元之间显色效果的精准性,进一步提高TFT显示模块的显色效果。
实施例二:
在该实施例中,背光模组包括背光板13和LCD光源14,LCD光源14包括但不限于底部平铺式设置或侧边式设置,背光板13设置于LCD光源14光线照射方向的背侧,现有技术中LCD光源14通常为平铺式和侧边式两种,移动式设备中侧边式较多,固定式显示设备通常采用底部平铺式方式,LCD光源14为点阵式设置的发光二极管。
实施例三:
在该实施例中,背光模组和第一偏光片1之间设置有导光板15,导光板15的光线出射路径处开设有点阵式设置的光线扩散膜孔16,导光板15的作用是将LCD光源14产生的光线向彩色滤光膜6方向垂直投射,其上设置的光线扩散膜孔16用于使得光线均匀投射,进而保证显示区域亮度均匀。
实施例四:
在该实施例中,液晶层3前后电极层5之间区域还设置有配向膜17,前后两侧的配向膜17上开设有相互垂直的配向槽18,配向膜17表面设置有一道道配向槽18,通过配向膜18相互夹着中间的液晶分子4,从而使得液晶分子4沿着配向槽18的方向排列。
一种TFT液晶显示器件的制作方法,采用上述的TFT液晶显示器件,将背光模组、导光板15、第一偏光片1、电极层5、配向膜17、液晶层3、彩色滤光膜6、第二偏光片7、基板11按照贴合顺序依次通过光学胶进行叠加贴合即可。
尽管已经示出和描述了本发明的实施例,对于本领域的普通技术人员而言,可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型,本发明的范围由所附权利要求及其等同物限定。
