下面将结合附图,对本申请实施例提供的一种显示装置的具体实施方式进行详细地说明。需要说明的是,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,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,都属于本申请保护的范围。
本申请实施例提供了一种显示装置,如图1至图4所示,其中,图1为垂直于显示装置出光面方向上的截面图,图2为第一种第一显示结构的结构示意图,图3为第二种第一 显示结构的结构示意图,图4为第三种第一显示结构的结构示意图。
参见图1所示,显示装置包括:背光模组10、位于背光模组10出光面的第一显示结构20、以及位于第一显示结构20远离背光模组10一侧的第二显示结构30;
第一显示结构20与第二显示结构30相对设置;
参见图2至图4所示,第一显示结构20包括呈阵列排布的第一像素22,第一像素22被划分为多个调光区(如图2和图3中的21,以及如图4中的21a和21b),调光区包括至少一个第一像素22;第一显示结构20用于:根据第二显示结构30在下一帧需显示的图像,调整各调光区对背光模组10发出的光线的透过率。
说明一点,第二显示结构30的作用为利用从第一显示结构20透过的背光源而显示图像,也就是说,第二显示结构30的作用可以理解为显示图像。第一显示结构20的作用为:根据第二显示结构30在下一帧需显示的图像,调整各调光区对背光模组10发出的光线的透过率,也就是说,第一显示结构20的作用为控制各调光区对背光模组10发出的背光源的透过率,所以第一显示结构20的作用可以理解为根据第二显示结构30在下一帧要显示的图像进行区域调光。
因此,在本申请实施例中,第一显示结构20主要用于区域调光,由于第一显示结构20中包括第一像素22,该第一像素22的设置结构可以类似于第二显示结构30中的第二像素(将在下面的内容进行介绍)的设置结构,所以第一像素22可以设置的相对较小,并且不会受到像背光模组10中光源那样的尺寸限制,进而第一显示结构20中每个调光区可以设置的较小,在显示装置需要显示高分辨率的画面时,通过调光区的作用,可以使得第二显示结构中亮暗差别比较大的区域之间进行细腻平滑的过渡,避免出现明显边界,在实现高对比度显示的同时,还可以实现高精度的显示,从而有效提高显示效果。
还需要说明的是,在本申请实施例中,为了实现第一显示结构和第二显示结构的功能,在显示装置中还可以包括一个驱动集成电路(Integrated Circuit,IC),图1至图4中均未示出驱动IC,驱动IC分别与第一显示结构和第二显示结构电连接,在驱动IC接收到待显示信号时,对该待显示信号进行处理,以得到第一控制信号和第二控制信号。
其中,第一控制信号可以理解为输出至第一显示结构中的各调光区的控制信号,以调整各调光区对背光源的透过率,实现区域调光。
第二控制信号可以理解为输出第二显示结构中的控制信号,以使得第二显示结构利用从第一显示结构透过的背光源显示图像,从而实现显示功能。
当然,显示装置中设置的驱动IC的数量还可以为两个,其中一个位于第一显示结构,另一个位于第二显示结构,两个驱动IC可以电连接也可以绝缘,可以根据实际需要进行设置。
为了使得两个驱动IC可以进行有效地配合工作,显示装置中还可以包括控制结构(例 如但不限于微控制器、或微处理器、或单片机等硬件结构),该控制结构分别与两个驱动IC电连接,控制结构与两个驱动IC之间的工作过程可以为:
在控制结构接收到待显示信号时,首先发送至第一显示结构中的驱动IC,以使该驱动IC对该待显示信号进行处理后得到控制信号,以调整各调光区对背光源的透过率,实现区域调光。同时,在第一显示结构中的驱动IC可以向控制结构进行反馈,已告知第一显示结构工作正常,可以进行正常地完成区域调光工作。
在控制结构接收到第一显示结构中的驱动IC的反馈之后,向第二显示结构中的驱动IC发送待显示信号,以在驱动IC的控制下,利用从第一显示结构透过的背光源显示图像,从而实现显示功能。
当然,上述只是举例说明控制结构与两个驱动IC之间的工作过程,在具体实施时,控制结构与两个驱动IC之间的交互过程并不限于上述内容所述,只要能够通过控制结构与两个驱动IC,使得第一显示结构实现区域调光的作用,以及第二显示结构实现显示作用即可,在此并不限定。
下面对第一像素22的设置情况进行说明。
在具体实施时,为了实现第二显示结构30的显示功能,在本申请实施例中,第二显示结构30包括呈阵列排布的第二像素;
其中,第一像素在显示装置出光面上的正投影的面积可以大于或等于第二像素在显示装置出光面上的正投影的面积。
如此,可以根据实际需要对第一像素进行设置,大大提高了设计的灵活性,以满足各种应用场景的需要。
对于第一像素内的结构设置,可以有以下几种情况:
情况1:
可选地,在本申请实施例中,第一像素在显示装置出光面上的正投影的面积等于第二像素在显示装置出光面上的正投影的面积;
第二像素包括一个第二像素电极,第一像素包括一个第一像素电极,第一像素电极与第二像素电极在显示装置出光面上的正投影形状相同。
例如但不限于,如图5所示的第一种第一像素的结构示意图,此处仅示出了第一像素电极22a在显示装置出光面上的正投影形状作为参考,而第二像素电极在显示装置出光面上的正投影形状可以参考图5中所示的第一像素,即第一像素电极22a在显示装置出光面上的正投影形状为矩形,同样地,第二像素电极在显示装置出光面上的正投影形状也为矩形。
此种情况1,可以适用于第二显示结构需要显示具有较高分辨率图像的场景,也就是说,为了能够在显示具有较高分辨率的图像时具有优异的显示效果,可以将调光区的面积 设置的较小,如此,可以使得第二显示结构中亮暗差别比较大的区域之间进行细腻平滑的过渡,避免出现明显边界,从而使得显示装置具有更加优异的显示效果,实现高精度且高对比度的显示。
具体地,在第一显示结构中包括多条栅线G和多条数据线D时,第一像素可以包括一个第一像素电极22a和晶体管22b,其中,第一像素电极22a通过晶体管22b与栅线G电连接,且通过晶体管22b与数据线D电连接,如图5所示。
那么此时,对于第二像素而言,同样可以包括:一个第二像素电极、以及晶体管,在第二显示结构中包括多条栅线多条数据线时,第二像素电极可以通过晶体管与栅线电连接,且通过晶体管与数据线电连接。也就是说,第二像素中包括的各结构之间的连接关系相同,所以第二像素的结构可以参见图5所示。
并且,对于第一像素而言,晶体管的在第一像素内的设置位置、晶体管的结构、晶体管的类型、以及第一像素电极在显示装置的出光面上的正投影形状,均可以与第二像素相同。
也就是说,第一像素与第二像素无论是在包括的结构、各结构之间的位置关系和连接关系、设置的尺寸大小等均设置为相同。如此,一方面,可以将第一显示结构与第二显示结构的结构设置为完全相同,以简化显示装置的复杂度,降低显示装置的制作难度;另一方面,不管第一显示结构显示怎样的画面,通过第二显示结构中调光区的作用,均可以保证显示装置具有优异的显示效果,从而满足不同的显示需求。
情况2:
可选地,在本申请实施例中,第一像素在显示装置出光面上的正投影的面积大于第二像素在显示装置出光面上的正投影的面积;
第二像素包括一个第二像素电极;
第一像素包括至少一个第一像素电极。
例如但不限于,如图6所示的第二种第一像素的结构示意图,第一像素22包括一个第一像素电极22a,如图7和图8所示,其中,图7为第三种第一像素的结构示意图,图8为第四种第一像素的结构示意图,第一像素22包括4个第一像素电极22a。
此种情况2所适用的第二显示结构的显示分辨率,要低于情况1中所适用的第二显示结构的显示分辨率。因显示分辨率的要求有所降低,所以调光区的面积与情况1中调光区的面积相比,可以设置的稍大一点。
如此,不仅可以使得第二显示结构中亮暗差别比较大的区域之间进行细腻平滑的过渡,避免出现明显边界,从而使得显示装置具有更加优异的显示效果,实现高精度且高对比度的显示,还可以有利于减少调光区的设置数量,以降低第一显示结构的驱动复杂度,降低第一显示结构的驱动功耗,从而降低显示装置的功耗,延长显示装置的使用时长。
在具体实施时,在本申请实施例中,虽然第一像素在显示装置出光面上的正投影的面积大于第二像素在显示装置出光面上的正投影的面积,但在设置第一像素和第二像素的结构时,可以包括结构设置为相同、以及结构设置为不同这两种情况。
在第一像素和第二像素的结构设置为相同时:
此时,若显示装置的显示分辨率为1920*1080,为了提高区域调光时调整的精度,可以将每个调光区的面积设置的较小,此时调光区的划分数量就会较多,例如调光区的划分数量为106~1920*1080,此时,第一像素和第二像素的结构可以设置为相同。
具体地,第一像素包括的结构以及各结构之间的连接关系,可以与第二像素相同。
例如,如图6所示,此处仅示出了第一像素22的结构作为参考,而第二像素的结构可以参考图6中所示的第一像素。第一像素22包括:一个第一像素电极22a、以及与该第一像素电极22a电连接的晶体管22b,其中该第一像素电极22a通过晶体管22b分别与栅线G和数据线D电连接。同样地,第二像素也可以包括一个第二像素电极和晶体管,其中该第二像素电极通过晶体管分别与栅线和数据线电连接。
如此,可以大大简化显示装置的结构复杂度,同时还可以降低显示装置的制作难度,降低制作成本。
在第一像素和第二像素的结构设置为不同时:
此时,若显示装置的显示分辨率为1920*1080,受到一些工艺条件限制或应用场景要求等其他因素的影响,每个调光区的面积可能会设置的较大,相应地调光区的划分数量就会较少,例如调光区的划分数量为500~106,但为了避免像素电极的负载过大对显示造成影响,可以对第一像素进行特殊设计,即第一像素和第二像素的结构可以设置为不同。
具体地,第一像素22包括多个第一像素电极22a,第一像素22可以包括多个呈轴对称或呈中心对称的第一像素电极22a,如图7和图8所示。
例如,参见图7和图8中所示,每个第一像素22中包括4个第一像素电极22a,且沿着中心对称点H呈中心对称设置,为了避免附图结构过于复杂,仅在图8中所示的左下角的第一像素22内示出了中心对称点H。
当然,第一像素中包括第一像素电极的数量并不限于4个,还可以是2个(未给出图示),对应的2个第一像素电极可以呈轴对称设置,或者,还可以是3个或5个等,可以根据需要进行设置,在此并不限定。
如此,可以使得显示装置在基于大视角时依然具有较高的对比度,从而使得显示装置在不同视角下均具有优异的显示效果,以适用于各种应用场景的需要。
具体地,在第一显示结构包括:多条沿行方向延伸且沿列方向排列的栅线、以及多条沿列方向延伸且沿行方向排列的数据线,且第一像素包括多个第一像素电极时,为了能够实现第一像素中的各第一像素电极分别与数据线和栅线电连接,在本申请实施例中,可以 有以下几种设置方式:
方式S1:
可选地,各调光区呈阵列排布,调光区包括多个第一像素;第一像素包括与第一像素电极一一对应设置的晶体管;也就是说,在第一像素包括多个第一像素电极时,相应地第一像素也包括多个晶体管,且晶体管与第一像素电极呈一一对应设置。
其中,同一调光区中:行方向上相邻两个第一像素中的第一像素电极通过对应设置的晶体管与同一数据线电连接,列方向上相邻两个第一像素中的第一像素电极通过对应设置的晶体管与同一栅线电连接。
例如,如图7所示,以调光区21c为例,包括四个第一像素,每个第一像素中均包括四个第一像素电极22a和四个晶体管22b,且每个第一像素电极22a均通过对应设置的晶体管22b分别与栅线G和数据线D电连接。其中,为了便于说明,为调光区21c中的四个第一像素按照从左向右和从上到下的顺序依次标记为:X1、X2、X3、X4。
第一像素X1与第一像素X2为行方向上相邻的两个第一像素,第一像素X1与第一像素X2中相邻的两个第一像素电极22a通过对应设置的晶体管22b均与同一条数据线D电连接。同理,第一像素X3与第一像素X4为行方向上相邻的两个第一像素,第一像素X3与第一像素X4中相邻的两个第一像素电极22a通过对应设置的晶体管22b均与同一条数据线D电连接。
第一像素X1与第一像素X3为列方向上相邻的两个第一像素,第一像素X1与第一像素X3中相邻的两个第一像素电极22a通过对应设置的晶体管22b均与同一条栅线G电连接。同理,第一像素X2与第一像素X4为列方向上相邻的两个第一像素,第一像素X2与第一像素X4中相邻的两个第一像素电极22a通过对应设置的晶体管22b均与同一条栅线G电连接。
因每个第一像素电极22a均通过对应设置的晶体管22b分别与数据线D和栅线G电连接,所以可以避免因第一像素内仅设置有一个晶体管22b且该晶体管22b发生故障无法正常工作而导致第一像素内的所有第一像素电极22a无法正常工作,进而可以有效缩小发生故障的面积,提高第一显示结构的可靠性。
并且,可以避免因晶体管的设置数量较多且行方向相邻两个第一像素电极与不同数据线电连接而导致的数据线设置数量增加的问题出现,以及避免因晶体管的设置数量较多且列方向相邻两个第一像素电极与不同栅线电连接而导致的栅线设置数量增加的问题出现,从而有利于减少在晶体管设置数量较多的情况下数据线和栅线的设置数量,进而简化第一显示结构的结构,降低第一显示结构的制作难度和制作成本,从而降低显示装置的制作难度和制作成本。
此外,列方向上相邻的两个调光区中相邻的两个第一像素电极通过对应设置的晶体管 分别与不同的栅线电连接,以及行方向上相邻的两个调光区中相邻的两个第一像素电极通过对应设置的晶体管分别与不同的数据线电连接。
如此,可以避免相邻调光区之间的干扰,进而避免对调光效果产生不良影响,提高显示装置的显示效果。
方式S2:
可选地,第一像素内设置有:与包括的各第一像素电极电连接的连接线、以及晶体管;
连接线与第一像素电极异层设置;
晶体管的栅极与栅线电连接,源极与数据线电连接,漏极与连接线电连接。
例如,如图8所示,第一像素22包括:四个第一像素电极22a、一个晶体管22b和一条连接线22c,其中四个第一像素电极22a通过连接线22c实现彼此之间的电连接,连接线22c通过晶体管22b分别与栅线G和数据线D电连接,所以间接地实现了四个第一像素电极22a通过晶体管22b分别与栅线G和数据线D电连接。
其中,连接线22c的设置形状并不限于图8所示,只要能够实现各第一像素电极22a与晶体管22b之间的电连接,均属于本申请实施例所要保护的范围。
如此,通过连接线的设置,可以减少第一像素内晶体管的设置数量,进而使得晶体管占用的第一像素内的空间减少,有利于提高第一像素的开口率,从而有利于降低第一显示结构的功耗,延迟显示装置的使用时长。
具体地,连接线可以与晶体管的栅极同材质且同层设置,未给出图示,从而有利于简化第一显示结构的制作工艺,进而降低第一显示结构的制作难度。
当然,连接线22c还可以与晶体管22b的源/漏极同材质且同层设置,如图9所示,该图为沿着图8中的n1-n2方向所示的剖视图,此时连接线22c可以与晶体管22b的漏极直接接触电连接,而无需通过过孔电连接,如此不仅可以降低第一显示结构的结构,降低第一显示结构的制作难度,还可以保证连接线22c与晶体管22b的漏极之间实现有效接触,避免了因通过过孔电连接时因过孔设置的较小而无法实现充分接触的问题出现,从而可以保证信号的有效传输。
在此情况2中,分别介绍了第一像素和第二像素的结构在相同或不同时的设置结果,但不管第一像素和第二像素的结构是否相同,其中第一像素电极与第二像素电极在显示装置的出光面上的正投影形状均可以设置为相同。
具体地,在本申请实施例中,第一像素电极和第二像素电极在显示装置的出光面上的正投影形状可以设置为:
参见图6所示,第一像素电极22a和第二像素电极均包括一个第一分部22a1和多个第二分部22a2,多个第二分部22a2均与第一分部22a1电连接,第一分部22a1沿第一方向延伸,多个第二分部22a2沿第一方向排布,各第二分部22a2之间具有间隙;
第二分部22a2包括:连接的第一段F1、第二段F2和第三段F3,第一段F1与第一分部22a1电连接,第二段F2设置在第一段F1与第三段F3之间,第一段F1沿第一子方向延伸,第二段F2沿第二子方向延伸,第三段F3沿第三子方向延伸;
其中,第一方向为行方向,第二子方向为列方向,第一子方向与第三子方向互相平行且分别与行方向和列方向相交;或,第一方向为列方向,第二子方向为行方向,第一子方向与第三子方向互相平行且分别与行方向和列方向相交。
例如但不限于,如图6所示,X方向表示行方向,Y方向表示列方向,M方向表示第一子方向,说明一点,X方向、Y方向和M方向均位于同一平面内。因第一子方向和第三子方向平行,所以M方向同样也可以表示第三子方向。第一分部22a1沿着Y方向延伸,第二分部22a2中的第一段F1和第三段F3均沿着M方向延伸,第二段F2沿着X方向延伸,第二分部22a2中的第一段F1与第二分部22a2连接,第二段F2用于连接第一段F1和第三段F3。
也就是说,第一像素电极和第二像素电极在显示装置的出光面上的正投影形状可以设置为相同(如图6所示的形状),只是尺寸大小不同而已。如此,因第一像素电极的尺寸相对较大,所以制作难度会随之降低,制作的产品良率会随之增加,因此可以大大提高显示装置的制作良率。
下面对调光区的设置情况进行说明。
在具体实施时,为了实现区域调光,在本申请实施例中,在设置调光区时,可以有以下几种方式:
方式K1:
可选地,在本申请实施例中,可以将各调光区在显示装置的出光面上的正投影形状设置为相同,且面积也可以设置为相同。
例如,如图3所示,调光区21的形状为正方形,每个调光区21中均包括9个第一像素22。
又例如,如图2所示,调光区21的形状为矩形。并且,在显示装置的形状也为矩形时,调光区21与显示装置的长宽比可以设置为相同。如若显示装置的长宽比为16:9,可以将调光区的长宽比也设置为16:9。
当然,图2和图3中只是示出了部分第一像素22,在第一显示结构中设置的第一像素22的数量并不限于图2和图3中所示,相应的设置的调光区21的数量也不限于图2和图3中所示。
如此,可以根据需要进行调光区的设置,提高设置的灵活性;因调光区的面积大小均相同,所以可以简化对各调光区的控制难度,从而降低对第一显示结构的驱动难度。
方式K2:
可选地,在本申请实施例中,第一显示结构包括:第一显示区域、以及围绕第一显示区域的第二显示区域;
调光区包括多个第一子区和多个第二子区,多个第一子区位于第一显示区域内,多个第二子区位于第二显示区域内;
第二子区的面积小于第一子区的面积。
例如但不限于,如图4所示,A表示整个显示区域,A1表示位于整个显示区域中心的第一显示区域,整个显示区域A中除了第一显示区域A1之外的区域为第二显示区域,图中未用标记标示出。第一显示区域A1内的第一子区用21b表示,且每个第一子区21b均包括6个第一像素22;位于第二显示区域内的第二子区用21a表示,且第二子区21a中至少包括一个第一像素22,至多包括三个第一像素22。
并且,各第二子区的面积和形状设置的并不都相同,可以根据实际情况而设置,在此并不限定。并且,各第一子区的面积和形状设置为相同,如图4中的矩形,但并不限于此。
也就是说,若将第一显示区域和第二显示区域之和看作是整个显示区域时,那么可以将第二显示区域看作是整个显示区域的边缘区域,将第一显示区域看作是整个显示区域的中心区域,将位于第二显示区域内的第一子区的面积设置的较小的一些,可以对整个显示区域的边缘区域进行精细地调整,从而可以消除显示装置边缘出现的锯齿等不良现象,提高显示装置的显示效果。
说明一点,第一显示结构中的整个显示区域,可以是与第二显示结构中的显示区域相对应的区域,面积大小可以设置为完全相同,如此,既可以保证通过第一显示结构实现区域调光,提高第二显示结构的显示效果,还可以避免因面积大小不同或错位产生的边缘漏光或边缘显示不良的问题出现,从而提高显示装置的显示效果。
基于上述说明,不管是采用上述哪种对于调光区的设置方式,均可以通过调光区对背光模组10发出的背光的透过率进行很好的控制和调整,例如,若显示装置的分辨率为1920*1080,调光区的划分数量可以为500-1920*1080个,若调光区的划分数量为14400个,且每个调光区的面积大小相同时,每个调光区包括的第一像素的数量可以为144个。
因此,通过调光区的区域调光的作用,在显示装置需要显示高分辨率的画面时,调光区可以实现高精度且高对比度的显示,从而有效提高显示效果。
在具体实施时,在本申请实施例中,在设置第一显示结构和第二显示结构的具体结构时,可以有几种:
第一种:
可选地,第一显示结构20和第二显示结构30可以均为液晶显示面板,如图10所示的第一种显示装置的结构示意图,此时,第一显示结构20与第二显示结构30之间设置有透明粘结层40,通过透明粘接层实现第一显示结构20与第二显示结构30的固定和粘结。 其中,透明粘结层40可以但不限于为聚乙烯醇(Polyvinyl Alcohol,PVA)胶材。
当然,第一显示结构20与第二显示结构30还可以通过框胶50进行固定,如图11所示的第二种显示装置的结构示意图,此时,框胶50中可以设置有其他材料(未给出图示),也可以填充空气(如图11所示)。其中,框胶50的制作材料可以是任何可以实现封装和粘结作用的材料,在此并不限定。
具体地,不管是上述哪种粘结方式,如图10所示,第一显示结构20包括:相对而置的第一基板1a和第二基板1b、位于第一基板1a和第一基板1a之间的第一液晶3a、以及位于第二基板1b远离第一基板1a一侧的上偏光片4和位于第一基板1a远离第二基板1b一侧的下偏光片5,其中,第一基板1a可以为阵列基板,第二基板1b可以为对向基板。
第二显示结构30包括:相对而置的第三基板2a和第四基板2b、位于第三基板2a和第四基板2a之间的第二液晶3b、以及位于第四基板2b远离第三基板2a一侧的上偏光片4和位于第三基板2a远离第四基板2b一侧的下偏光片5,其中,第三基板2a可以为阵列基板,第四基板2b可以为对向基板。
其中,对于属于同一个显示结构的两个偏光片,透过上偏光片4和下偏光片5的偏振光的偏振方向垂直,对于第一显示结构20的下偏光片5和第二显示结构30的上偏光片4,透过两个偏光片的偏振光的偏振方向平行。以便于实现显示功能。
例如但不限于,如图12所示,该图为与图10和图11对应的各偏光片的对光的偏振方向的示意图,图中仅示出了4个偏光片,若将第一显示结构20中包括的上偏光片和下偏光片分别标记为P3和P4,将第二显示结构30中包括的上偏光片和下偏光片分别标记为P1和P2,那么透过P1的偏振光的偏振方向为X方向时,透过P2的偏振光的偏振方向为Y方向,透过P3的偏振光的偏振方向为Y方向,透过P4的偏振光的偏振方向为X方向。
说明一点,第一显示结构20中包括的第一液晶3a和第二显示结构30中包括的第二液晶3b的偏转方向的设置可以根据需要进行设置,只要能够实现显示功能,均属于本申请实施例所要保护的范围。
由于第一显示结构和第二显示结构均为液晶显示面板,且结构基本类似,所以可以同时制作出第一显示结构和第二显示结构,以便于提高显示装置的制作效率。
第二种:
可选地,在本申请实施例中,如图13所示的第三种显示装置的结构示意图、以及图14所示的第四种显示装置的结构示意图,显示装置包括:第一偏光片6、第二偏光片7、第三偏光片8;
第一偏光片6设置于第二显示结构30远离背光模组10的一侧,第二偏光片7设置于第一显示结构20与第二显示结构30之间,第三偏光片8设置于第一显示结构20靠近背光模组10的一侧;
透过第一偏光片6的偏振光与透过第二偏光片7的偏振光互相垂直,透过第一偏光片6的偏振光与透过第三偏光片8的偏振光互相平行。
也就是说,显示装置中包括三个偏光片,其中,第一偏光片6和第三偏光片8对光的偏振方向相同,第一偏光片6和第二偏光片7对光的偏转方向垂直。
如此,通过设置三个偏光片,便可以实现显示装置的显示功能,不仅简化了显示装置的结构,还有利于实现轻薄化的设计。
具体地,如图13所示,第一显示结构20可以包括:相对而置的第一基板1和第二基板2、以及设置于第一基板1与第二基板2之间的第一液晶3a;其中,第一基板1可以理解为阵列基板,第二基板2可以理解为对向基板。
此时,第二显示结构30可以包括:相对设置的第三基板2a和第四基板2b、以及位于第三基板2a与第四基板2b之间的第二液晶3b;第三基板2a包括像素电极,第三基板2a靠近第一基板1设置。其中,第三基板2a也可以理解为阵列基板,第四基板2b可以理解为对向基板。
需要注意的是,图13中所示的显示装置与图11和图12相比,偏光片的设置数量不同,即图13中所示的显示装置中包括的偏光片的设置数量要少,如此,可以有利于减少显示装置的厚度,实现轻薄化的设计。
第三种;
可选地,在此种设置结构中,显示装置同样也包括第一偏光片、第二偏光片和第三偏光片,且三个偏光片的设置位置和作用与上面介绍的第二种结构相同,不同的是:第一显示结构中包括一个基板而不是两个基板。
具体地,显示装置的结构还可以如图14所示,第一显示结构20可以包括第一基板1a、以及设置于第一基板1a与第二偏光片7之间的第一液晶3a;其中,第一基板1a可以理解为阵列基板。
第二显示结构30包括:相对设置的第三基板2a和第四基板2b、以及位于第三基板2a与第四基板2b之间的第二液晶3b;第三基板2a包括像素电极,第三基板2a靠近第一基板1a设置。其中,第三基板2a也可以理解为阵列基板,第四基板2b可以理解为对向基板。
并且,第一基板1a包括:像素电极和公共电极,图14中未示出;像素电极和公共电极均用于驱动第一液晶发生偏转。
需要注意的是,图14中所示的显示装置与图13相比,基板的设置数量不同,即图14中所示的显示装置中包括的基板的设置数量要少,如此,可以有利于减少显示装置的厚度,实现轻薄化的设计。
并且,第三种结构中第一显示结构并不包括对向基板,所以并不存在因对向基板使得第一显示结构发出的光线出现损耗的问题,从而使得显示装置具有更优异的显示效果。
说明一点,在图13中,第一显示结构20包括对向基板(即第二基板1b),第一液晶3a位于对向基板和阵列基板(即第一基板1a)之间,在图14中,第一显示结构20不包括对向基板(即第二基板1b),所以第二液晶3b位于阵列基板和第二偏光片7之间。
在具体实施时,在本申请实施例中,背光模组的设置结构可以有以下两种:
可选地,背光模组可以包括:侧入式光源、以及位于侧入式光源出光面的导光板,未给出图示,通过导光板可以改变侧入式光源发射出的光线的传播方向,从而使得光线从背光模组的出光面发射出去,进入至第一显示结构中。
此时,该种结构的背光模组可以称之为侧入式的背光模组。
因该种结构的背光模组制作成本与直下式的背光模组(下面内容中进行介绍)的制作成本相比较低,所以由侧入式的背光模组构成的显示装置的制作成本较低,同时还可以实现高精度且高对比度的显示,有效提高显示效果。
当然,背光模组除了包括侧入式光源和导光板之外,还包括其他用于实现背光模组功能的结构,具体结构可参见目前技术中对背光模组的描述,在此不再赘述。
可选地,背光模组可以包括光源基板,光源基板上设置有呈阵列排布的光源,光源可以由LED构成,且光源基板也可以称之为LED基板,未给出图示。
其中,光源发射出的光源从背光模组的出光面直接射出,所以此种结构的背光模组可以称之为直下式的背光模组。
虽然此种结构的背光模组与上述侧入式的背光模组相比制作成本要高,但直下式的背光模组可以实现区域调光,所以由该种结构的背光模组构成的显示装置中,可以通过背光模组和第一显示结构均进行区域调光,从而进一步提高显示对比度,提高显示效果。
当然,背光模组除了包括光源基板之外,还包括其他用于实现背光模组功能的结构,具体结构可参见现有技术中对背光模组的描述,在此不再赘述。
显然,本领域的技术人员可以对本申请实施例进行各种改动和变型而不脱离本申请实施例的精神和范围。这样,倘若本申请实施例的这些修改和变型属于本申请权利要求及其等同技术的范围之内,则本申请也意图包含这些改动和变型在内。
