Description

一种和大尺寸TFT屏一体化的液晶仪表盘
技术领域
本发明涉及液晶显示技术领域,特别涉及一种和大尺寸TFT屏一体化的液晶仪表盘。
背景技术
近年来,液晶显示器凭借着体积小、功耗低等优点已经越来越广泛的深入普通百姓的生活,被越来越多的使用在仪器仪表、家居用品、车载仪表盘等多个领域。其种类多且繁杂。而且不同类型的液晶显示器又都有着自己的优缺点,比如VA模式的显示器对比度好、开模成本不高、外形灵活,但是显示内容单一;TFT型显示器对比度好、显示内容丰富多彩,但是价格昂贵,而且市场上更多的是固定规格的标准品,很难实现产品的个性化。有的时候为了显示多个内容甚至在一面控制墙上同时存在多块多种液晶显示器,这样一块一块的补丁结构不符合大众的审美观。因此一种既美观又实用的设计思路应运而生。
发明内容
为了解决背景技术中所述问题,本发明提供一种和大尺寸TFT屏一体化的液晶仪表盘,将TFT显示屏与VA型仪表盘一体化显示,既美观又实用。
为了达到上述目的,本发明采用以下技术方案实现:
一种和大尺寸TFT屏一体化的液晶仪表盘,所述的仪表盘包括VA型LCD屏,所述的VA型LCD屏由上至下依次包括上偏光片、液晶盒和下偏光片,所述液晶盒自上而下包括上ITO玻璃基板、上PI取向层、液晶层、下PI取向层和下ITO玻璃。
所述的仪表盘还包括TFT液晶屏和第一LED背光,所述的VA型LCD屏的显示区分为固定图素显示区和预留图素显示区,所述的TFT液晶屏贴合在VA型LCD屏的下方,与预留图素显示区位置相对应;所述的第一LED背光贴合在VA型LCD屏的下方,与固定图素显示区位置相对应。
所述的液晶盒的光程差为Δn*d=300~400nm。
所述的VA型LCD屏上偏光片与下偏光片的透过轴相互垂直,下偏光片的透过轴与下方的TFT屏的上偏光片透过轴相平行。
所述的VA型LCD屏的上ITO玻璃基板和下ITO玻璃基板的玻璃厚度范围为0.4mm~1.1mm,ITO导电膜方阻范围为15Ω/□~120Ω/□,ITO导电膜分别按照固定图形将固定图素显示区的上下ITO刻蚀,预留图素显示区面积大于TFT显示区面积,不刻蚀。
所述的TFT液晶屏与VA型LCD屏之间采用海绵或双面胶进行贴合。
所述的TFT液晶屏设有第二LED背光。
与现有技术相比,本发明的有益效果是:
1、本发明与常规VA型液晶显示器的设计相比,特点在于在设计该液晶盒内部的图形时特意预留了一面较大的空间,可以完全覆盖放置在下方的TFT屏。这样就可以实现当上方VA型液晶显示器不工作时,整体产品呈现的就是VA显示器的黑色外观;而当上方VA型液晶显示器运行时,如果不点亮同样可以起到遮挡下方TFT屏的作用,如果点亮下方TFT屏的显示内容就可以透过该大块图素呈现在整个仪表盘表面。达到了既美观又实用的目的。
2、本发明采用液晶盒的光程差为Δn*d=300~400nm,与常规的液晶盒相比,能够增加透过率,同时通过设定刻蚀图案和偏光片的偏广角,能够保证TFT液晶屏的透过显示效果。

以下结合附图对本发明提供的具体实施方式进行详细说明。
如图1-3所示,一种和大尺寸TFT屏一体化的液晶仪表盘,包括VA型LCD屏1、TFT液晶屏4、第一LED背光,所述的VA型LCD屏1的显示区分为固定图素显示区2和预留图素显示区3,所述的TFT液晶屏4贴合在VA型LCD屏1的下方,与预留图素显示区3位置相对应;所述的第一LED背光包括左LED背光5和右LED背光6,所述的左LED背光5和右LED背光6贴合在VA型LCD屏1的下方,与固定图素显示区2位置相对应。其中,左LED背光5与固定图素显示区2的左部位置相对应,右LED背光6与固定图素显示区2的右部位置相对应。
所述的TFT液晶屏4与VA型LCD屏1之间采用海绵或双面胶进行贴合。
所述的TFT液晶屏4为整体的TFT液晶显示器,包括显示模组7,还有LED背光8。TFT液晶屏4自身绑定IC。
如图4所示,所述的VA型LCD屏由上至下依次包括上偏光片9、液晶盒10和下偏光片11,如图5所示,所述液晶盒10自上而下包括上ITO玻璃基板12、上PI取向层13、液晶层14、下PI取向层18和下ITO玻璃19。
