一种具有提高对比度结构的LCD显示器及显示设备
本申请要求于2021年07月23日提交中国专利局、申请号为202110835169.9、发明名称为“一种具有提高对比度结构的LCD显示器”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本发明涉及显示器领域,具体而言,涉及一种具有提高对比度结构的LCD显示器及显示设备。
背景技术
随着技术的演进,显示行业已经开始逐步从LCD(液晶显示器)过渡到OLED(有机二极管显示器),相比OLED的艳丽高动态,LCD在动态范围上有着明显的劣势,即LCD对比度不足。相比OLED动辄几十上百万的对比度,常规的LCD只有的1000-3000的对比度。如此对比度大大的限制的LCD的动态范围,使得LCD在进行HDR playback的时候明显的效果差于OLED显示器。
传统方案中传统的LCD显示技术由白色背光加TFT-cell,cell两侧贴偏光片,但由于偏光片的透过率和偏振度互斥,一般偏振度在90-99%之间,即总有一小部分光线会泄露,导致LCD的黑暗部分不够黑从而使LCD对比度只能维持在800-2000的水准。
图1为传统的方案,100是CF(彩色滤光片),200是array(TFT阵列,主动开关矩阵;TFT-薄膜场效应管),300背光,400是BM(blackmatrix-黑色矩阵),500是下偏光片,600是上偏光片;传统方案中通过红绿蓝子像素的开关切换从而实现颜色、亮暗的变化。
技术问题
由于偏光片的偏振度无法达到理论上的100%以及LCD盒内各膜层复杂的透射、反射、折射关系使得像素并不能完全关闭,即背光的光线总会有泄露穿透LCD到达人眼,故LCD对比度无法像OLED那样做到几十上百万。

如图2所示,本申请提出一种具有提高对比度结构的LCD显示器,包括:背光层1、背光控制层2及光显示层3;所述背光层1、背光控制层2及光显示层3依次连接;其中,所述背光层1用于发出光源,所述背光控制层2对所述背光层1发出的光进行过滤;所述光显示层3上设置有光显示面305,所示光显示面305显示所述背光控制层2过滤后的可见光。
本发明具有提高对比度结构的LCD显示器中,包括:背光层1、背光控制层2及光显示层3;所述背光层1、背光控制层2及光显示层3依次连接;其中,所述背光层1用于发出光源;所述背光控制层2对所述背光层1发出的光源进行过滤;所述光显示层3上设置有光显示面305,所示光显示面305显示所述背光控制层2过滤后的可见光。在背光层1和光显示层3之间设置背光控制层2,通过设置背光控制层2对光的透过进行像素级的过滤控制,从而实现将光显示层3的黑区或暗区部分的光阻隔至极小的亮度,使得达到光显示层3的光线无法穿透显示面305,继而实现光显示层3的显示面305的超高对比度。
具体地,本发明所提出的方案是一种具备量产可行性的技术方案,通过在背光层1和光显示层3之间设置背光控制层2,背光控制层2对光进行过虑,可以大幅度的提升LCD显示器的对比度,从而提升LCD显示器的观感体验。
现有方案的LCD一般仅能实现800-2000的对比度,通过本申请可以将对比度提升几十上百倍至接近OLED对比度的水准。
传统LCD是由cell(主动TFT阵列加装液晶盒)加背光组成,而传统的背光属于面光源,无法做到针对局部控制;本发明通过增加下液晶盒以达到对背光可以做局部控制,从而实现超高对比度的目的。
本申请创新性的提出一种新架构,采用双LCD重叠的方案。设置下层LCD作为背光控制层2对背光的透过进行像素级的控制,从而实现将光显示层3的局部的暗区背部的背光阻隔至极小的亮度,再通过做为光显示层3的上层LCD的像素操作,从而使得达到光显示层3的光线基本无法穿透光显示层3的显示面305,继而实现超高对比度。
具体地,这种上下两层LCD的架构设置中,做为背光控制层2的下层LCD可以将背光进行选择性通过;光显示层3的显示面305中一般都是由明、暗不同的区域构成,为了提高显示面305的对比度,暗区需要压制光,明区则不需要;通过将阻隔暗区的亮度,使得明区相对的显示为更亮,从而使显示面305对比度极大提高。
实施例中,所述背光控制层2包括第一偏光片201及与所述第一偏光片201层叠设置的第一玻璃基板,所述第一偏光片201与所述背光层1连接,所述第一玻璃基板与所述光显示层3连接;所述第一偏光片201将所述背光层1发出的光转变为偏振光,液晶扭转穿偏振光的偏振角度。设置与背光层1连接的第一偏光片201,第一偏光片201用于将穿过该偏光片的光线转换偏振光;光线由背光层1射出,穿过第一偏光片201后变成偏振光,通过第一玻璃基板的液晶加电可以控制光线的偏振角度。所述第一下璃基板202和所述第一上玻璃基板203之间设置有液晶层(图中未标示),所述液晶层扭转偏振光的偏振角度。
实施例中,所述第一玻璃基板包括第一下璃璃基板202及第一上玻璃基板203,所述第一上玻璃基板203与所述第一下玻璃基板202层叠设置;所述第一下玻璃基板202与所述第一偏光片201连接,所述第一上玻璃基板203与所述光显示层3连接。第一玻璃基板包括上下层叠设置的两层,即包括第一下玻璃基板202和第一上玻璃基板203;第一下玻璃基板202与第一偏光片201连接,第一上玻璃基板203与光显示层3的第二偏光片301连接。第一偏光片201将穿过的光转成偏振光,通过下第一下玻璃基板202的液晶加电可以控制光线的偏振角度。
实施例中,所述第一上玻璃基板203内设置有控制光像素的像素点结构204。像素点结构204是组成背光控制层2最小单元的控制像素。
实施例中,所述光显示层3包括第二偏光片301及第二玻璃基板,所述第二偏光片301与所述第二玻璃基板层叠设置,所述第二偏光片301与所述第一上玻璃基板203连接;所述第二偏光片201对穿过所述第一上玻璃基板203后的光进行过滤。穿过第一玻璃基板的光,被第一下玻璃基板202扭转,扭转后的光线穿过第二偏光片301后会被过滤掉一部分(局部被扭曲到与第二偏光片301方向垂直的光线);未被第二偏光片301过滤的光接下来就进入上到层LCD,即光显示层3。
实施例中,所述第二玻璃基板包括第二上玻璃基板303和第二下玻璃基板302,所述第二上玻璃基板303与所述第二下玻璃基板302层叠设置,所述第二下玻璃基板302与所述第二偏光片201连接。将第二玻璃基板设置为上下层叠的两侧,即包括第二上玻璃基本303和第二下玻璃基板302;第二下玻璃基板302与第二偏光片301连接,第二上玻璃基板303与第三偏光片304连接。
实施例中,所述第二上玻璃基板303为彩色滤光片,所述第二下玻璃基板302为薄膜场效应管的阵列。将第二上玻璃基板303设置为彩色滤光片,将第二下玻璃基板302设置为薄膜场效应管,并将薄膜场效应管进行阵列。
实施例中,所述光显示层3还包括用于显示可见光的第三偏光片304,所述第三偏光片304与所述第二上玻璃基板303连接。光线穿过第二偏光片301后会被过滤掉一部分,穿过第二偏光片301的光经过第二玻璃基板的RGB子像素的偏正角度调制后再穿过第三偏光片304就在第三偏光片304的显示面305形成了可以到达人眼被看见的光线。
实施例中,所述光显示层3还包括用于防止像素混色的网格层306,所述网格层306设置在所述第二上玻璃基板303内。穿过第三偏光片304的光被显示前,还结果设置在第二上玻璃基板303内的网格层306;该网格层306对红R、绿G、蓝B子像素进行隔离,防止像素混色;网格层306类似一张黑色的网格。
实施例中,所述将背光控制层2设置为背光控制的液晶盒,所述光显示层3为显示光的液晶盒。
本发明整体的工作过程大致为:
光线由背光层1射出,穿过第一偏光片201后变成偏振光;通过下第一下玻璃基板202的液晶加电以及根据加电的情况可以控制光线的偏振角度;光穿过第一下玻璃基板202的光会被扭转,被第一下玻璃基板202扭转的光线穿过第二偏光片301后会被过滤掉一部分(局部被扭曲到与第二偏光片301偏振方向垂直的光线);穿过第二偏光片301的光接下来就会进入到上层LCD,也就是光显示层3;经过第二上玻璃基板303的RGB子像素的偏正角度调制后再穿过第三偏光片304,并在第三偏光片304的显示面305形成可以到达人眼被看见的光线。
上述提到的被扭曲的光与第二偏光片301垂直方向的区域即为画面的暗区,对应的控制液晶盒光的过滤的操作,目的就是为了降低暗区的背光供给。从而降低暗区的亮度,使得对比度显著提高。
本发明具有提高对比度结构的LCD显示器中,包括:背光层1、背光控制层2及光显示层3;所述背光层1、背光控制层2及光显示层3依次连接;其中,所述背光层1用于发出光源;所述背光控制层2对所述背光层1发出的光源进行过滤;所述光显示层3上设置有光显示面305,所示光显示面305显示所述背光控制层2过滤后的可见光。在背光层1和光显示层3之间设置背光控制层2,通过设置背光控制层2对光的透过进行像素级的过滤控制,从而实现将光显示层3的暗区部分的光阻隔至极小的亮度,使得达到光显示层3的光线无法穿透显示面305,继而实现光显示层3的显示面305的超高对比度。
本发明还提供一种显示设备,该显示设备包括具有提高对比度结构的LCD显示器,所述显示设备可以为:手机、平板电脑、电视机、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或装置。
