为使本公开的上述目的、特征和优点能够更为明显易懂,下面将结合附图和实施例对本公开做进一步说明。然而,示例实施方式能够以多种形式实施,且不应被理解为限于在此阐述的实施方式;相反,提供这些实施方式使得本公开更全面和完整,并将示例实施方式的构思全面地传达给本领域的技术人员。在图中相同的附图标记表示相同或类似的结构,因而将省略对它们的重复描述。本公开中所描述的表达位置与方向的词,均是以附图为例进行的说明,但根据需要也可以做出改变,所做改变均包含在本公开保护范围内。本公开的附图仅用于示意相对位置关系不代表真实比例。
人眼在观察现实世界的时候,依靠双目视差产生立体视觉。依据该原理设计的3D显示装置通常需要配合眼镜等设备,将入射给左眼和右眼的光线分开,从而达到三维显示的效果。上述方式实现的三维立体显示通常将人眼长期聚焦在同一位置,这会造成视觉疲劳,进而使用户产生眩晕等不良体验。
基于光场技术的三维显示可以克服以上问题,实现裸眼3D显示。光场显示是在显示面板的出光侧设置微透镜阵列,显示面板的出射光经过微透镜阵列的调制形成多个视点入射到人眼,人眼观看到的图像来自于不同视点,因此观看到的图像来源于不同方向,与人眼观看真实景物的情形类似,克服视觉疲劳的问题。
图1为本公开实施例提供的显示装置的结构示意图之一,图2为本公开实施例提供的显示装置的截面结构示意图。
如图1和图2所示,本公开实施例提供的显示装置,包括:
衬底基板10,衬底基板10一般位于显示装置的底部,具有支撑以及承载其它部件的作用。衬底基板10的尺寸通常与显示装置的尺寸基本相同,形状通常情况下设置为矩形。当显示装置为异形显示装置时,衬底基板的形状和尺寸与显示装置相适应。衬底基板的材料通常情况下采用玻璃,在此不做限定。
多个像素岛20,位于衬底基板10上;像素岛20包括多个不同颜色的子 像素p,所有子像素p沿第一方向x和第二方向y呈阵列排布,一个像素岛20中颜色相同的子像素p沿第一方向x排列成一行,不同颜色的子像素p行沿第二方向y排列,第一方向x和第二方向y交叉。
在具体实施时,每个像素岛20的结构可以一致,各像素岛20沿第一方向x和第二方向y呈阵列排布。
图3a为本公开实施例提供的像素岛的子像素排列结构示意图。
如图3a所示,一个像素岛20中可以包括三基色的子像素,例如,像素岛20包括红色子像素pr、绿色子像素pg和蓝色子像素pb。其中,红色子像素pr、绿色子像素pg和蓝色子像素pb的数量相同;红色子像素pr沿第一方向x排列成一行,绿色子像素pg沿第一方向x排列成一行,蓝色子像素pb沿第一方向x排列成一行;红色子像素行、绿色子像素行和蓝色子像素行沿第二方向y排列,从而使像素岛20中的子像素呈阵列排布。上述的第一方向x和第二方向y可以为相互垂直的两个方向,其中第一方向x可以为水平方向,第二方向y可以为竖直方向,在此不做限定。
如图2所示,本公开实施例提供的显示装置还包括:微透镜层30。微透镜层60位于像素岛20背离衬底基板10的一侧。微透镜层30由微透镜阵列构成,微透镜层30可以对像素岛30的出射光线进行调制,从而使像素岛20映射为进行图像显示的像素阵列。采用像素岛20配合微透镜层30的结构,可以在达到子像素物理排列极限的基础上提高成像的分辨率。
图3b为本公开实施例提供的像素岛映射后的像素排列结构示意图。
当采用图3a所示结构的像素岛,在配合微透镜层30进行像素映射之后,可以形成如图3b所示的像素排列结构,由图3b中可以看出,映射后的红色子像素pr、绿色子像素pg和蓝色子像素pb按照固定顺序进行排列,且相邻的一个红色子像素pr、一个绿色子像素pg和一个蓝色子像素pb构成一个像素。映射后的像素与传统的像素排列结构相同,一个像素岛可以映射为多个像素构成的像素阵列,从而采用像素岛结构可以提高图像的显示分辨率。
微透镜层30不仅用于对像素岛中的子像素进行像素映射,还能够对像素 岛的出射光线进行调制,从而使最终的像素岛的显示数据形成多个视点,从而实现三维光场显示。
在具体实施时,微透镜层30可以采用至少一个液晶透镜。通过对液晶透镜施加电信号可以控制液晶分子产生设定的相位延迟,从而等效为透镜的作用。当然,上述微透镜层也可以直接采用具有设定形状的微透镜构成的微透镜阵列实现相同的功能,在此不做限定。如下以微型透镜层采用液晶透镜的情形对微透镜层的结构以及功能进行说明,采用实体微透镜的设置方式以及原理与液晶透镜类似,不进行具体赘述。
微透镜层30可以仅包括一个液晶透镜,该液晶透镜等效为半球形的微透镜构成的微透镜阵列,该液晶透镜同时起到像素映射和实现三维光场显示。像素岛中的子像素的出射光线在经过液晶透镜之后,可以映射为像素阵列,且形成多个视点,从而实现三维光场显示。
例如,当像素岛20采用图3a所示的结构时,微透镜层30可以采用(或等效)为16个半球形微透镜呈阵列排布于像素岛20的出光侧,从而可以使像素岛20映射为图3b所示的像素阵列,形成最多16个视点,实现光场三维显示。
在另一些实施例中,微透镜层30也可以采用两层液晶透镜,其中靠近像素岛一侧的液晶透镜可以起到像素映射的作用,远离像素岛一侧的另一个液晶透镜可以对出射光线进行调制,实现三维光场显示。两层透镜均可以采用半球形微透镜结构,微透镜的数量与像素岛中的子像素数量相匹配,在此不做限定。
在另一些实施例中,微透镜层30包括的两层液晶透镜中,其中一层液晶透镜用于等效为半球形的微透镜构成的微透镜阵列,而另一层液晶透镜用于等效为柱状透镜构成的微透镜阵列,两个液晶透镜不同时被控制,对光线的调制原理不同,采用半球形透镜的微透镜阵列可以实现三维光场显示,采用柱状透镜的微透镜以实现超多视点的三维显示。
例如,当像素岛20采用图3a所示的结构时,其中一层液晶透镜可以等 效为16个柱状透镜,分别对应不同的子像素列,从而使像素岛的出射光可以被映射为图3b所示的像素阵列,同时实现一部分光线向左眼的方向偏折,而另一部分光线向右眼的方向偏折,从而实现三维显示。另一层液晶透镜可以等效为16个半球形微透镜呈阵列排布于像素岛20的出光侧,从而可以使像素岛20映射为图3b所示的像素阵列,形成最多16个视点,实现光场三维显示。
本公开实施例不对像素岛中的子像素数量及其对应的液晶透镜的使用数量,以及如何控制液晶透镜以实现三维显示的操作手段进行限定。
如图1所示,在显示装置包括采用上述像素岛的像素排列结构的基础上,显示装置还包括:
多条数据线40,沿第一方向x排列且沿第二方向y延伸;沿第二方向y排列成同一列的子像素连接同一条数据线40。数据线40用于向子像素传输图像数据,子像素在显示出图像数据相应的亮度。
多路复用电路50,沿第二方向y位于所有像素岛20所在区域的一侧。各数据线40分别连接多路复用电路50。多路复用电路50应用于显示装置中,可以采用少量的驱动引脚分时驱动不同的数据线,由此减少驱动引脚的使用数量,节省资源。
驱动芯片60,沿第二方向y位于多路复用电路50背离像素岛20的一侧。多路复用电路50连接驱动芯片60。驱动芯片60具有多个连接引脚,多路复用电路50的输入端连接到驱动芯片60的引脚,多路复用电路50的输出端依次连接各数据线40,其中,输入端的数量少于输出端的数量。驱动芯片60的引脚输出的图像数据可以通过多路复用电路50向各数据线40进行传输,这样驱动芯片60的一个引脚可以控制多条数据线40。
控制器70,连接驱动芯片60,被配置为向驱动芯片60提供驱动信号。控制器70可以接收用于图像显示的二维图像数据或三维图像数据,控制器70根据用户选择的确定当前的显示模式为三维显示模式还是二维显示模式。再根据预先确定出的显示分区把相应的图像数据提供给驱动芯片60,驱动芯片 60根据控制器70的控制以设定的驱动电流向各数据线提供图像数据。
在具体实施时,可以将显示装置的中心区域作为高清显示区,除中心区域以外的其它区域作为辅助显示区;从而使得中心区域以高分辨率进行图像显示,辅助显示区以低分辨率进行图像显示,这样可以在不降低显示效果的同时节省功耗。
本公开实施例提供的显示装置还可以包括摄像头c,摄像头c被配置为对用户的眼睛进行拍摄,以使控制器70根据摄像头c拍摄的图像确定用户在显示装置的注视区域,控制驱动芯片60驱动注视区域以高分辨率进行图像显示,驱动非注视区域以低分辨率进行图像显示。
图4为本公开实施例提供的显示装置的局部放大图之一。
如图4所示,一个像素岛20中的子像素列沿第一方向x分为多个子像素组21,每个子像素组21中包括的子像素列的数量相等。
多路复用电路50包括多个沿第一方向x排列的第一多路复用单元51,第一多路复用单元51包括一个输入端51i和多个输出端51o;一个第一多路复用单元51对应连接一个子像素组21,第一多路复用单元51的输出端51o分别连接子像素组对应的数据线40,第一多路复用单元51的输入端51i连接驱动芯片60。
在本公开实施例中,一个子像素组21写入的图像数据通过一个第一多路复用单元51进行传输。当第一多路复用单元51的输出端51o依次打开时,输入端51i输入的图像数据可以依次地传输到子像素组21对应的不同的数据线40上,这样不同的数据线40可以向子像素传输不同的图像数据。当一个像素岛20内的各子像素写入不同的图像数据时,可以形成的视点数量最多,从而进行高分辨率的图像显示。而当第一多路复用单元51的输出端51o同时打开时,输入端51i输入的图像数据同时传输到子像素组21对应的不同的数据线40上,这样不同的数据线40可以向子像素传输相同的图像数据。当一个子像素组21内的同行子像素写入相同的图像数据时,相当于多个像素用于显示相同的图像数据,这样可以降低视点的数量,从而进行低分辨率的图像 显示。
根据上述驱动规则,可以控制显示装置被用户注视的注视区进行高分辨率的图像显示,控制非注视区进行低分辨的图像显示,从而可以降低非注视区的数据传输量,减少非注视区的像素充电时间,将节省下来的时间用于提高图像的刷新率,从而使得注视区具有较佳的显示效果,同时降低显示装置的功耗。
可选地,如图4所示,多路复用电路50还包括:多条第一开关控制信号线l1,第一开关控制信号线l1沿第一方向x延伸沿第二方向y排列。
第一多路复用单元51包括:多个第一开关晶体管T1,第一开关晶体管的控制极连接第一开关控制信号线l1,第一开关晶体管的第一极连接第一多路复用单元的输出端51o,第一开关晶体管的第二极连接第一多路复用单元的输入端51i。
如图4所示,一个第一多路复用单元51中包含的第一开关晶体管T1的数量与第一开关控制信号线l1的数量相等。一个第一多路复用单元51中,各第一开关晶体管T1的控制极分别连接不同的第一开关控制信号线l1,各第一开关晶体管T1的第一极分别连接第一多路复用单元的不同的输出端51o,各第一开关晶体管T1的第二极均连接至第一多路复用单元的输入端51i。
第一多路复用单元51中的各第一开关晶体管T1在各第一开关控制信号线l1的控制下打开或关闭。这样当各第一开关控制信号线l1依次输出有效电平信号,以使各第一开关晶体管T1依次打开时,输入端51i的信号依次通过各第一开关晶体管T1第二极向第一极传输,从而可以依次向各第一开关晶体管T1连接的不同的数据线传输不同的图像数据,使得多列子像素写入不同的图像数据进行高分辨率的图像显示。当各第一开关信号线l1同时输出有效电平信号时,可以控制各第一开关晶体管T1同时打开,那么输入端51i的信号通过各第一开关晶体管T1的第二极向第一极传输,从而可以通过各第一开关晶体管T1向多条数据线40同时输出,使得多列子像素可以同时写入相同的图像数据进行低分辨率的图像显示。
图5为本公开实施例提供的显示装置的局部放大图之二。
如图5所示,多路复用电路50还包括:多个控制单元c。控制单元c沿第二方向y位于第一多路复用单元51背离像素岛20的一侧,控制单元c沿第一方向x排列。控制单元c包括一个输入端ci和一个输出端co;一个控制单元c对应连接一个第一多路复用单元c,控制单元的输出端co连接第一多路复用单元51的输入端51i,控制单元c的输入端ci连接驱动芯片60。
由图5可以看出,第一多路复用单元51是通过控制单元c与驱动芯片60连接的,控制单元c用于控制是否启动第一多路复用单元51向数据线40传输图像数据,即控制单元c相当于第一多路复用单元51的开关,只有当控制单元c处于开启状态下,第一多路复用单元51才可以实现上述驱动;当控制单元c处于关闭状态,则无法控制第一多路复用单元51。
可选地,多路复用电路50还包括:沿第一方向x延伸的控制信号线lc。
控制单元c包括:控制开关晶体管Tc;控制开关晶体管Tc的控制极连接控制信号线lc,控制开关晶体管Tc的第一极连接控制单元的输出端co,控制开关晶体管Tc的第二极连接控制单元的输入端ci。
控制开关晶体管Tc在控制信号线lc的控制下打开或关闭。当控制信号线lc输出有效电平信号时,控制开关晶体管Tc打开,输入端ci的信号通过控制开关晶体管Tc的第二极向第一极传输,使得驱动芯片输出的图像数据可以通过控制开关晶体管Tc传输给第一多路复用单元51,再经过第一多路复用单元51传输给其连接的各数据线40。当控制信号线lc未输出有效电平信号时,控制开关晶体管Tc关闭,则驱动芯片输出的图像数据无法再通过控制开关晶体管Tc向第一多路复用单元51传输,此时第一多路复用单元51无效。
本公开实施例提供的上述显示装置可以进行三维光场显示,通过控制第一多路复用单元51中的第一开关晶体管T1可以实现视点数量的控制,从而控制显示装置的显示分辨率。
如图5所示,在本公开实施例提供的显示装置中,多路复用电路50还可以包括:多个第二多路复用单元52.第二多路复用单元52沿第二方向y位于 第一多路复用单元51背离像素岛20的一侧,第二多路复用单元52沿第一方向x排列。第二多路复用单元52包括多个输入端52i和多个输出端52o,输入端52i的数量小于输出端52o的数量;一个第二多路复用单元52对应连接沿第一方向x排列的多个像素岛20,第二多路复用单元52的输出端52o分别连接各像素岛中的各子像素列对应的数据线40,第二多路复用单元52的输入端52i分别连接驱动芯片60。
第二多路复用单元52同时连接多个像素岛20,通过这样的连接关系可以依次向各像素岛20传输不同的图像数据,或同时向多个像素岛20传输相同的图像数据,由此可以在控制像素岛产生的视点数量的同时控制像素岛20传输数据的分辨率,从而控制显示装置的图像分辨率。
可选地,如图5所示,多路复用电路50还包括:
多条第二开关控制信号线l2,第二开关控制信号线l2沿第一方向x延伸沿第二方向y排列;
多条第三开关控制信号线l3,第三开关控制信号线l3沿第一方向x延伸沿第二方向y排列。
由图5可以看出,第一开关控制信号线l1、第二开关控制信号线l2、第二开关控制信号线l3以及控制信号线lc的延伸方向相同,均可以沿第一方向x延伸沿第二方向y排列。
第二多路复用单元52包括:多个第二开关晶体管T2和多个第三开关晶体管T3。
其中,第二开关晶体管T2的控制极连接第二开关控制信号线l2,第二开关晶体管T2的第一极连接第二多路复用单元52的输出端52o,第二开关晶体管T2的第二极连接第三开关晶体管T3的第一极;第三开关晶体管T3的控制极连接第三开关控制信号线l3,第三开关晶体管T3的第二极连接第二多路复用单元52的输入端52i。
在本公开实施例中,一个第二多路复用单元52中包含的第二开关晶体管T2的数量与一个第二多路复用单元52连接的数据线40的数量相等。例如, 一个第二多路复用单元52连接两个像素岛20,每个像素岛20包括16列子像素,那么一个像素岛20连接16条数据线,两个像素岛20连接32条数据线,则第二多路复用单元52中包含32个第二开关晶体管T2。
一个第二多路复用单元52中包含的第三开关晶体管T3的数量与一个像素岛20包括的子像素列的数量相等。例如,一个像素岛20包括16列子像素,那么第二多路复用单元52中包含16个第三开关晶体管T3。
一个第二多路复用单元52中,连接同一个像素岛20的第二开关晶体管T2的控制极连接同一条第二开关控制信号线l2,连接不同的像素岛20的第二开关晶体管T2的控制极连接不同的第二开关控制信号线l2;连接各像素岛20中相同位置的子像素列的第二开关晶体管T2的第二极相互连接。
图6为本公开实施例提供的第二多路复用单元的局部放大图。
如图6所示,以一个第二多路复用单元同时控制两个像素岛为例,每个像素岛包括16列子像素,多路复用电路中包含两条第二开关控制信号线(l21和l22);连接第一个像素岛201的16个第二开关晶体T21的控制极连接第一条第二开关控制信号线l21,连接第二个像素岛202的16个第二开关晶体管T22的控制极连接第二条第二开关控制信号线l22。连接第一个像素岛201的第一列子像素的第二开关晶体管T21的第二极与连接第二个像素岛202的第一列子像素的第二开关晶体管T22的第二极连接在一起;连接第一个像素岛201的第二列子像素的第二开关晶体管T21的第二极与连接第二个像素岛202的第二列子像素的第二开关晶体管T22的第二极连接在一起;以此类推,使得连接第一个像素岛的各第二开关晶体管的第二极分别与连接第二个像素岛相同位置的各第二开关晶体管的第二极相互连接。
当两条第二开关控制信号线依次传输有效电平信号时,可以分别向第一个像素岛201和第二个像素岛202传输图像数据。具体地,当第一条第二开关控制信号线l21传输有效电平信号,而第二条第二开关控制信号线l22无信号时,连接第一个像素岛201的各第二开关晶体管T21打开,连接第二个像素岛202的各第二开关晶体管T22关闭。那么驱动芯片60输出的图像数据可 以通过连接第一个像素岛201的各第二开关晶体管T21向第一像素岛201的各数据线进行传输。当第一条第二开关控制信号线l21无信号,而第二条第二开关控制信号线l22传输有效电平信号时,连接第一个像素岛201的各第二开关晶体管T21关闭,连接第二个像素岛202的各第二开关晶体管T22打开。那么驱动芯片60输出的图像数据可以通过连接第二个像素岛202的各第二开关晶体管T22向第二像素岛202的各数据线进行传输。由此实现第一像素岛201和第二像素岛202分别写入不同的图像数据。
当两条第二开关控制信号线同时传输有效电平信号时,可以同时别向第一个像素岛201和第二个像素岛202传输相同图像数据。具体地,当第一条第二开关控制信号线l21和第二条第二开关控制信号线l22同时传输有效电平信号时,连接第一个像素岛201的各第二开关晶体管T21和连接第二个像素岛202的各第二开关晶体管T22同时打开。那么驱动芯片60输出的图像数据可以通过连接第一个像素岛201的各第二开关晶体管T21向第一像素岛201的各数据线进行传输,同时通过连接第二像素岛202的各第二开关晶体管T22向第二个像素岛202的各数据线进行传输。此时,第一个像素岛201和第二像素岛202写入的图像数据相同,在进行图像显示时,相当于增大了进行图像显示的像素的尺寸,降低了图像分辨率。
如图5所示,一个第二多路复用单元52中,各第三开关晶体管T3与第二多路复用单元52所连接的其中一个像素岛20对应;该像素岛20对应第三开关晶体管T2和第二开关晶体管T3中,各第三开关晶体管T3的第一极分别连接各第二开关晶体管T2的第二极。
由于对应不同像素岛相同位置的子像素列的多个第二开关晶体管T2的第二极连接在一起,因此只需要对一个像素岛对应的第二开关晶体管T2的第二极传输图像数据,配合第二开关控制信号线传输有效电平信号,就可以达到对多个像素岛进行数据写入的目的,由此可以节省驱动引脚。
在本公开实施例中,第三开关晶体管T3的数量与一个像素岛20包括的子像素列的数量相等。例如,一个第二多路复用单元52连接两个像素岛,第 一个像素岛包括16列子像素,那么需要采用32个第二开关晶体管T2,采用16个第三开关晶体管。16个第三开关晶体管T3的第一极分别与连接一个像素岛的16个第二开关晶体管T2的第二极连接。这样可以通过第三开关晶体管T3向第二开关晶体管T2传输图像数据。
如图5所示,一个第二多路复用单元52中,第三开关晶体管T3沿第一方向x分为多个第三开关晶体管组T3s,第三开关晶体管组T3s的数量与一个像素岛20中包括的子像素组21的数量相等;一个第三开关晶体管组T3s中,各第三开关晶体管T3的控制极分别连接不同的第三开关控制信号线l3,各第三开关晶体管T3的第二极连接第二多路复用单元52的同一个输入端52i。
在本公开实施例中,一个子像素组21写入的图像数据通过一个第三开关晶体管组T3s进行控制传输,因此一个第二多路复用单元52包含的第三开关晶体管组T3s的数量与一个像素岛20包含的子像素且21的数量相等。除此之外,每个第三开关晶体管T3s中包含的第三开关晶体管T3的数量与多路复用电路50包含的第三开关控制信号线l3的数量相同。
各第三开关晶体管T31在各第三开关控制信号线l3的控制下打开或关闭。这样当各第三开关控制信号线l3依次输出有效电平信号,以使各第三开关晶体管T3依次打开时,输入端52i的信号依次通过各第三开关晶体管T31第二极向第一极传输,从而可以依次向其连接的各第二开关晶体管T2传输不同的图像数据。进一步地,在第二开关控制信号线l2的控制下控制图像数据同时或依次传输给不同的像素岛。当各第三开关信号线l3同时输出有效电平信号时,可以控制各第三开关晶体管T3同时打开,那么输入端52i的信号通过各第三开关晶体管T3的第二极向第一极传输,从而可以同时向其连接的各第二开关晶体管T2传输相同的图像数据。进一步地,在第二开关控制信号线l2的控制下控制图像数据同时或依次传输给不同的像素岛。
如图6所示,本公开实施例提供的显示装置,还包括:栅极驱动电路80和栅线800。其中:
多条栅线800,沿第一方向x延伸且沿第二方向y排列;沿第一方向c排 列成同一行的子像素连接同一条栅线800;
栅极驱动电路80,沿第一方向x位于像素岛20所在区域的一侧或两侧;栅线800分别连接栅极驱动电路80。栅极驱动电路80包括多个沿第二方向y排列的栅极驱动单元81,各栅极驱动单元81沿第二方向y相互级联,各栅极驱动单元81单独扫描对应的子像素行。
驱动芯片60中的图像数据需要配合栅极驱动电路80输出的扫描信号写入到像素岛20中,当栅极驱动电路80向栅极传输扫描信号时,该行子像素在栅极800传输有效电平信号时才能将图像数据通过数据线40写入到该行的各子像素中。在本公开实施例中,通过控制相邻多行子像素岛的扫描信号相同,可以实现同时控制多行多列子像素岛的图像数据,从而可以更大程度地分辨率调节。
需要说明的是,本公开实施例提供的上述显示装置可以采用第一多路复用单元51进行驱动,也可以采用第二多路复用单元52进行驱动。当采用第一多路复用51单元进行驱动时,各控制单元c保持打开状态,第二多路复用单元52均无信号传输,此时可以控制显示装置进行视点数量的切换,从而达到调整显示分辨率的目的;当采用第二多路复用单元52进行驱动时,各控制单元c保持关闭状态,第一多路复用单元51均无信号传输,此时可以控制显示装置同时进行视点数量以及像素岛分辨率的切换,从而达到调整显示分辨率的目的。
本公开实施例以一个具体实例对电路连接关系进行说明。
图7为本公开实施例提供的显示装置的局部放大图之三。

多路复用电路50包括多个第二多路复用单元,一个第二多路复用单元52对应连接沿第一方向x排列的两个像素岛,两个像素岛区分为第一像素岛201和第二像素岛202。
多路复用电路50包括两条第二开关控制信号线l2和四条第三开关控制信号线l3。一个第二多路复用单元52包括32个第二开关晶体管T2,第一像素岛201的数据线对应连接16个第二开关晶体管T2,第二像素岛202的数量线对应连接16个第二开关晶体管T2。对应于第一像素岛201的16六个第二开关晶体管T2的控制极均连接其中一条第二开关控制信号线l2,对应于第二像素岛202的16六个第二开关晶体T2的控制极均连接另一条第二开关控制信号线l2。对应于第一像素岛201的各第二开关晶体管T2的第一极一一对应连接第一像素岛201的各数据线,对应于第二像素岛202的各第二开关晶体管 T2的第一极一一对应连接第二像素岛202的各数据线。第一像素岛201的第一列子像素连接的第二开关晶体管T2的第二极与第二像素岛202的第一列子像素连接的第二开关晶体管T2的第二极相互连接,第一像素岛201的第二列子像素连接的第二开关晶体管T2的第二极与第二像素岛202的第二列子像素连接的第二开关晶体管T2的第二极相互连接,以此类推,第一像素岛201的第十六列子像素连接的第二开关晶体管T2的第二极与第二像素岛202的第十六列子像素连接的第二开关晶体管T2的第二极相互连接。
一个第二多路复用单元52包括16个第三开关晶体管T3,16个第三开关晶体管T3对应于第一像素岛201,16个第三开关晶体管T3沿第一方向x分为四个第三开关晶体管组。
一个第三开关晶体管组T3s中的4个第三开关晶体管T3的控制极一一对应连接四条第三开关控制信号线l2,对应于同一个子像素列的第二开关晶体管T2的第二极连接第三开关晶体管T3的第一极,4个第三开关晶体管T3的第二极相互连接,连接至驱动芯片60。
如图7所示,显示装置还包括沿第一方向x位于像素岛一侧的栅极驱动电路,栅极驱动电路包括多个相互级联的栅极驱动单元(811-816),栅极驱动单元分别通过一条栅极与一行子像素连接。当栅极驱动单元(811-816)向对应的各栅极输出扫描信号时,通常情况下各行子像素对应的栅极中依次传输有效电平信号。第一行子像素在栅线传输有效电平信号的时段可以将对应的数据线上的图像数据写入到子像素中;在第一行子像素写入图像数据结束之后,第二行子像素在栅线传输有效电平信号的时段将对应的数据线上的图像数据写入到子像素中;以此类推,在所有的子像素均写入图像数据之后可以实现一帧图像显示。
在本公开实施例提供的上述显示装置中,当采用第一多路复用单元51进行驱动时,控制开关晶体管Tc保持打开状态,第二多路复用单元52无信号传输。此时可以通过控制第一多路复用单元51中的4个第一开关晶体管T1依次打开,以使对应的4列子像素依次写入图像数据,此时一个像素岛产生 多个视点,进行高分辨率图像显示;或者可以通过控制4个第一开关晶体管T1同时打开,以使对应的4列子像素同时写入相同的图像数据,此时可以减少一个像素岛产生的视点数量,进行低分辨率图像显示。
当采用第二多路复用单元52进行驱动时,控制开关晶体管Tc保持关闭状态,第一多路复用单元51无信号传输。此时可以通过控制对应第一像素岛201的16个第二开关晶体管T2先打开,向第一像素岛201写入图像数据,再控制对应第二像素岛202的16个第二开关晶体管T2打开,向第二像素岛202写入图像数据,保持不同的像素岛写入的图像数据不同,进行高分辨率图像显示;或者可以通过控制对应第一像素岛201和第二像素岛202的32个第二开关晶体管T2同时打开,向第一像素岛201和第二像素岛202写入相同的图像数据,在保持像素岛产生视点数量不变的情况下降低图像分辨率,进行低分辨率图像显示。与此同时,还可以控制栅极驱动单元801和804传输相同的扫描信号,栅极驱动单元802和805传输相同的扫描信号,栅极驱动单元803和806传输相同的扫描信号,以使第一像素岛201、第二像素岛202、第三像素岛203和第四像素岛204写入相同的图像数据,进一步降低图像分辨率。
在控制第一像素岛201和第二像素岛202对应的第二开关晶体管T2依次打开或同时打开时,还可以控制一个第三开关晶体管组T3s中的4个第三开关晶体管T3依次打开,以使对应的4列子像素依次写入图像数据,此时一个像素岛产生多个视点;或者可以通过控制4个第三开关晶体管T3同时打开,以使对应的4列子像素同时写入相同的图像数据,此时可以减少像素岛产生的视点数量示。
本公开实施例提供的上述显示装置可以进行上述图像分辨率的调整,以在被用户注视的显示区域实现高分辨的图像显示,在其它显示区域实现低分辨率的图像显示,由此在保证用户体验的前提下降低功耗,达到资源的合理分配。
基于上述显示装置结构,本公开实施例还提供一种显示装置的驱动方法, 图8为本公开实施例提供的显示装置的驱动方法的流程图。
如图8所示,本公开实施例提供的显示装置的驱动方法包括:
S10、实时确定用户在显示装置的注视区域和非注视区域;
S20、驱动注视区域以第一分辨率进行图像显示,驱动非注视区域以第二分辨率进行图像显示。
其中,第一分辨率高于第二分辨率。
本公开实施例通过设定手段确定出显示装置所显示图像的注视区域和非注视区域,驱动注视区域以高分辨率进行图像显示,驱动非注视区以低分辨率进行图像显示,从而保证被关注的注视区域的图像显示质量,降低非注视区的图像分辨率,从而降低整体功耗,避免资源浪费。
在上述步骤S10中,实时确定用户在显示装置的注视区域和非注视区域,包括:
控制摄像头实时对用户的眼睛进行拍摄;
根据摄像头拍摄的图像确定用户在显示装置的注视区域;
将显示装置中除注视区域以外的其它区域确定为非注视区域。
在具体实施时,显示装置的显示图像通常较大,人眼只会注视显示图像的局部区域,因此本公开实施例通过在显示装置上设置摄像头,或外接摄像头实时地跟踪人眼在显示装置的注视区域,从而实时地驱动注视区域以高分辨率进行图像显示,驱动非注视区域以低分辨率进行图像显示,避免资源浪费。
具体地,根据摄像头拍摄的图像确定用户在显示装置的注视区域,包括:
根据摄像头拍摄的图像分别确定用户的左眼和右眼相对于显示装置的显示面的位置;
根据用户的左眼和右眼相对于显示装置的显示面的位置,以及用户与显示装置之间的距离,分别确定出用户的左眼在显示装置的左眼注视区域和用户的右眼在显示装置的右眼注视区域;
将左眼注视区域和右眼注视区域的交叠区域作为用户在显示装置的注视 区域。
其中,用户的单个眼睛在显示装置的注视区域可以采用以下公式确定:
S=π(A tan15
°)
2;
S表示用户的单个眼睛在显示装置的注视区域,A表示用户与显示装置之间的距离。
图9a为本公开实施例提供的人眼产生注视区域的原理图之一,图9b为本公开实施例提供的人眼产生注视区域的原理图之二。
如图9a和图9b所示,人眼观看显示装置时通常会具有一极限视角,即人眼在相对于显示装置的显示面的位置固定时,在注视显示装置时只能观看到视角范围之内的内容。通常情况下单眼产生的视角约为30度,如图9a所示,当用户的双眼到显示装置的距离为A1时,左眼在显示装置上产生左眼注视区域为sl1,右眼在显示装置产生的右眼注视区域为sr1,左眼注视区域和右眼注视区域的交叠区域sx1确定为用户双眼在显示装置的注视区域。如图9b所示,当用户的双眼到显示装置的距离为A2时,左眼在显示装置上产生左眼注视区域为sl2,右眼在显示装置产生的右眼注视区域为sr2,左眼注视区域和右眼注视区域的交叠区域sx2确定为用户双眼在显示装置的注视区域。对比图9a和图9b,当用户到显示装置的距离由A1减小到A2时,按照单眼的视角为30度来计算,在显示装置产生的注视区域从sx1缩小为sx2。由此可见,用户双眼在显示装置产生的注视区域取决于视角以及用户到显示装置的距离,在视角固定的前提下,用户距离显示装置越远,产生的注视区域越大。
在确定出用户在显示装置的注视区域之后,可以驱动注视区域进行高清显示,而其它非注视区域进行低清显示,从而节省资源。
图10为本公开实施例提供的显示装置的显示分区示意图,图11为图10所示显示装置的显示效果示意图。
如图10所示,可以将显示区域沿着栅极驱动电路的延伸方向划分为多个区域,以图10所示的结构,本公开实施例可以将显示区域划分为16个分区,16个分区分别采用16个栅极驱动单元(GOA1-GOA16)独立驱动。如果通 过摄像头等设备确定出的用户在显示装置的注视区域为图10中黑色框所对应的区域,那么注视区域受栅极驱动单元GOA5-GOA9驱动。对注视区域和非注视区域内的各子像素写入图像数据之后,显示效果如图11所示,注视区域进行高清图像显示,非注视区域进行低清图像显示,由此节省资源和功耗。当用户的注视相对于显示装置的注视位置产生变化时,实时变更相应区域的驱动方式,实现高清图像和低清图像的动态调整。
在进行图像显示之前,还需要确定用户选择的显示模式,当用户选择二维显示模式时,显示装置输入的图像数据为二维图像数据,当用户选择三维显示模式时,显示装置输入的图像数据为三维图像数据。
因此,在上述步骤S20中,驱动注视区域以第一分辨率进行图像显示,驱动非注视区域以第二分辨率进行图像显示,具体包括:
在用户选择的显示模式为二维显示模式时,驱动注视区域以第一分辨率进行二维图像显示,驱动非注视区域以第二分辨率进行二维图像显示;

当用户选择的显示模式为二维显示模式时,显示装置输入的图像数据为二维图像数据,用户希望观看的显示图像为二维图像,而用户在显示装置只会注视显示装置的部分区域,那么此时,针对注视区域以高分辨率进行二维图像显示,针对非注视区域以低分辨率进行二维图像显示,可以避免资源浪费。
当用户选择的显示模式为三维显示模式时,显示装置输入的图像数据为三维图像数据,用户希望观看的显示图像为三维图像,而用户在显示装置只会注视显示装置的部分区域,那么此时,针对注视区域以高分辨率进行三维图像显示,针对非注视区域可以低分辨率进行二维图像显示或三维图像显示,由此保证注视区域具有较好的显示效果,同时降低非注视区域的数据传输量 和充电时间,节省功耗。

在用户选择的显示模式为三维显示时,驱动注视区域以第一分辨率进行三维图像显示,驱动非注视区域以第二分辨率进行三维图像显示,包括:

在用户选择的显示模式为三维显示时,驱动注视区域以第一分辨率进行三维图像显示,驱动非注视区域以第二分辨率进行二维图像显示,包括:
接收三维图像数据,将非注视区域对应的三维图像数据转化为二维图像数据;
针对注视区域对三维图像数据进行第一分辨率的图像渲染,针对非注视 区域对二维图像数据进行第二分辨率的图像渲染;
控制注视区域对应的各第一开关控制信号线依次输出有效电平信号,以使第一多路复用单元中的各第一开关晶体管依次打开传输不同的三维图像数据,控制非注视区域对应的各第一开关控制信号线同时输出有效电平信号,以使第一多路复用单元中的各第一开关晶体管同时打开传输相同的二维图像数据,以实现驱动注视区域以第一分辨率进行三维图像显示,驱动非注视区域以第二分辨率进行二维图像显示。
本公开实施例可以采用第一多路复用单元驱动实现上述图像显示,具体的驱动电路可以采用4所示的结构。图12a为本公开实施例提供的注视区域对应的驱动时序图之一,图12b为本公开实施例提供的非注视区域对应的驱动时序图之一。
如图4所示,每个像素岛连接四个第一多路复用单元51,每个第一多路复用单元51包括四个第一开关晶体管T1,多路复用电路包括四条第一开关控制信号线l1,四条第一开关控制信号线输出的开关控制信号分别为图12a所示的SW1-SW4。各行子像素对应的栅极传输的扫描信号分别为图12a所示的G1、G2…,驱动芯片输出的图像数据为图12a所示的D。
如图12a所示,对于注视区域内的各第一多路复用单元51,使四条第一开关控制信号线l1依次输出有效电平信号(高电平信号),从而使对应的四个第一开关晶体管T1依次打开用于向像素岛各列子像素输出不同的图像数据。
具体来说,当第一条栅线输出扫描信号G1为有效电平时段(高电平时段)时,其它栅线输出扫描信号为低电平。在第一条栅线输出有效电平时段期间,第一条第一开关控制信号线先输出高电平信号(SW1为高电平),其它三条第一开关控制信号线均输出低电平信号(SW2-SW41为低电平),此时只有连接第一条第一开关控制信号线的第一开关晶体管打开,驱动芯片输出的图像数据通过第一个第一开关晶体管传输给像素岛的第一列子像素;而后第二条第一开关控制信号线输出高电平信号(SW2为高电平),其它三条第一开关控制信号线均输出低电平信号(SW1、SW3、SW4为低电平),此时只有连接第二 条第一开关控制信号线的第一开关晶体管打开,驱动芯片输出的图像数据通过第二个第一开关晶体管传输给像素岛的第二列子像素;而后第三条第一开关控制信号线输出高电平信号(SW3为高电平),其它三条第一开关控制信号线均输出低电平信号(SW1、SW2、SW4为低电平),此时只有连接第三条第一开关控制信号线的第一开关晶体管打开,驱动芯片输出的图像数据通过第三个第一开关晶体管传输给像素岛的第三列子像素;而后第四条第一开关控制信号线输出高电平信号(SW4为高电平),其它三条第一开关控制信号线均输出低电平信号(SW1-SW3为低电平),此时只有连接第四条第一开关控制信号线的第一开关晶体管打开,驱动芯片输出的图像数据通过第四个第一开关晶体管传输给像素岛的第四列子像素。在完成上述图像数据的传输之后,第一条栅线输出扫描信号G1为有效电平时段结束,第二条栅线输出扫描信号G2变为有效电平(高电平),各第一多路复用单元重复上述操作,以此类推,使注视区域内的各子像素依次写入图像数据,实现注视区域的高分辨率的图像显示。
如图12b所示,对于非注视区域内的各第一多路复用单元51,使四条第一开关控制信号线l1同时输出有效电平信号(高电平信号),从而使对应的四个第一开关晶体管T1同时打开用于向像素岛各列子像素输出相同的图像数据。
具体来说,当第一条栅线输出扫描信号G1为有效电平时段(高电平时段)时,其它栅线输出扫描信号为低电平。在第一条栅线输出有效电平时段期间,四条第一开关控制信号线同时输出高电平信号(SW1-SW4为高电平),此时连接四条第一开关控制信号线的四个第一开关晶体管同时打开,驱动芯片输出的图像数据通过四个第一开关晶体管同时传输给像素岛的四列子像素。在完成上述图像数据的传输之后,第一条栅线输出扫描信号G1为有效电平时段结束,第二条栅线输出扫描信号G2变为有效电平(高电平),各第一多路复用单元重复上述操作,以此类推,使非注视区域内的每四列子像素同时写入相同的图像数据,从而使图像分辨率降低4倍,实现非注视区域的低分辨率的图像显示。
当用户选择的显示模式为二维显示模式时,驱动芯片通过各第一多路复用单元传输的图像数据为二维图像数据,注视区域和非注视区域均进行二维图像显示,且注视区域的图像分辨率大于非注视区域的图像分辨率。当用户选择的显示模式为三维显示模式时,注视区域和非注视区域可以均进行三维图像显示,或者注视区域可以进行三维图像显示,非注视区域可以进行二维图像显示。针对上述两种情况,驱动芯片通过各第一多路复用单元向注视区域传输三维图像数据,向非注视区域传输三维图像数据或二维图像数据。然而控制器输入的图像源为三维图像数据或二维图像数据,那么在注视区域进行三维图像显示,而在非注视区域进行二维图像显示时,需要将非注视区域内的三维图像数据转化为二维图像数据之后再向非注视区域对应的各第一多路复用单元传输。另外,控制器在将图像数据输出给驱动芯片之前,会对图像数据进行相应的图像渲染,图像渲染的规则可以参见已有技术,在此不做赘述。
本公开实施例提供的显示装置可以同时包括第一多路复用单元和第二多路复用单元,本公开实施例也可以采用第一多路复用单元协同第二多路复用单元驱动实现上述图像显示,具体的驱动电路可以采用5所示的结构。图13a为本公开实施例提供的注视区域对应的驱动时序图之二,图13b为本公开实施例提供的非注视区域对应的驱动时序图之二。
如图5所示,每个像素岛连接四个第一多路复用单元51,每两个像素岛连接一个第二多路复用单元52。每个第一多路复用单元51包括四个第一开关晶体管T1,多路复用电路包括四条第一开关控制信号线l1,四条第一开关控制信号线l1输出的开关控制信号分别为图13a所示的SW1-SW4。每个第二多路复用单元52包括32个第二开关晶体管T2、16个第三开关晶体管T3和一个控制开关晶体管Tc;多路复用单元包括两条第二开关控制信号线l2、四条第三开关控制信号线l3和一条控制信号线lc。两条第二开关控制信号线l2输出的开关控制信号分别为图13a所示的SWO-SWE,四条第三开关控制信号线l3输出的开关控制信号分别为图13a所示的SWb-SWe,控制信号线lc输出的 开关控制信号为图13a所示的SWa。各行子像素对应的栅极传输的扫描信号分别为图13a所示的G1、G2…,驱动芯片输出的图像数据为图13a所示的D。
如图13a和图13b所示,可以使控制信号线lc输出有效电平信号(高电平信号),各第二开关控制信号线l2和各第三开关控制信号线l3均输出低电平,由此使第二多路复用单元52关闭,采用第一多路复用单元进行驱动。
如图13a所示,针对注视区域,使四条第一开关控制信号线l1依次输出有效电平信号(高电平信号),从而使对应的四个第一开关晶体管T1依次打开用于向像素岛各列子像素输出不同的图像数据。
具体来说,当第一条栅线输出扫描信号G1为有效电平时段(高电平时段)时,其它栅线输出扫描信号为低电平。在第一条栅线输出有效电平时段期间,第一条第一开关控制信号线先输出高电平信号(SW1为高电平),其它三条第一开关控制信号线均输出低电平信号(SW2-SW41为低电平),此时只有连接第一条第一开关控制信号线的第一开关晶体管打开,驱动芯片输出的图像数据通过第一个第一开关晶体管传输给像素岛的第一列子像素;而后第二条第一开关控制信号线输出高电平信号(SW2为高电平),其它三条第一开关控制信号线均输出低电平信号(SW1、SW3、SW4为低电平),此时只有连接第二条第一开关控制信号线的第一开关晶体管打开,驱动芯片输出的图像数据通过第二个第一开关晶体管传输给像素岛的第二列子像素;而后第三条第一开关控制信号线输出高电平信号(SW3为高电平),其它三条第一开关控制信号线均输出低电平信号(SW1、SW2、SW4为低电平),此时只有连接第三条第一开关控制信号线的第一开关晶体管打开,驱动芯片输出的图像数据通过第三个第一开关晶体管传输给像素岛的第三列子像素;而后第四条第一开关控制信号线输出高电平信号(SW4为高电平),其它三条第一开关控制信号线均输出低电平信号(SW1-SW3为低电平),此时只有连接第四条第一开关控制信号线的第一开关晶体管打开,驱动芯片输出的图像数据通过第四个第一开关晶体管传输给像素岛的第四列子像素。在完成上述图像数据的传输之后,第一条栅线输出扫描信号G1为有效电平时段结束,第二条栅线输出扫描信号 G2变为有效电平(高电平),各第一多路复用单元重复上述操作,以此类推,使注视区域内的各子像素依次写入图像数据,实现注视区域的高分辨率的图像显示。
如图13b所示,针对非注视区域,使四条第一开关控制信号线l1同时输出有效电平信号(高电平信号),从而使对应的四个第一开关晶体管T1同时打开用于向像素岛各列子像素输出相同的图像数据。
具体来说,当第一条栅线输出扫描信号G1为有效电平时段(高电平时段)时,其它栅线输出扫描信号为低电平。在第一条栅线输出有效电平时段期间,四条第一开关控制信号线同时输出高电平信号(SW1-SW4为高电平),此时连接四条第一开关控制信号线的四个第一开关晶体管同时打开,驱动芯片输出的图像数据通过四个第一开关晶体管同时传输给像素岛的四列子像素。在完成上述图像数据的传输之后,第一条栅线输出扫描信号G1为有效电平时段结束,第二条栅线输出扫描信号G2变为有效电平(高电平),各第一多路复用单元重复上述操作,以此类推,使非注视区域内的每四列子像素同时写入相同的图像数据,从而使图像分辨率降低4倍,实现非注视区域的低分辨率的图像显示。
对比图12a和图12b,以及对比图13a和图13b可知,每列子像素的充电时间为1t,当一个第一多路复用单元51中的四个第一开关晶体管T1依次打开分别为四列子像素充电时,需要的时长为4t;当一个第一多路复用单元51中的四个第一开关晶体管同时打开同时为四列子像素充电时,需要的时长为1t。由此可见,非注视区域的子像素充电时长为注视区域的子像素充电时长的1/4,那么注视区域对应的栅极驱动单元的扫描时长将大于非注视区域对应的栅极驱动单元的扫描时长。具体地,非注视区域对应的栅极驱动单元输出有效电平的时长可以缩短为注视区域对应的栅极驱动单元输出有效电平时长的1/4,非注视区域的第一多路复用单元的开启次数相比注视区域降低3/4,功耗降低为原来的1/4。由于非注视区域的充电时间缩短,节省下来的时间可以用于提高显示图像的刷新率,或者也可以用于增加注视区域的刷新率,从而提 高显示效果。
举例来说,如果显示装置包括2000行子像素,其中注视区域包括1000行子像素,非注视区域包括1000行子像素。每个子像素的充电时间为t。那么如果按照传统的驱动方法对每个子像素依次充电,那么充电时间需要2000*4*t=8000t;而采用本公开实施例提供的上述驱动方案,对于注视区域,控制各列子像素依次充电,需要的充电时间为1000*1*t,对于非注视区域,控制多列子像素同时充电,需要的充电时间为1000*4*t,总的充电时间为1000*1*t+1000*4*t=5000t。由此可见,采用本公开实施例提供的驱动方案可以缩短整体充电时间,那么节省的时间可以用来提高显示装置的刷新频率,根据上述举例可以将整体刷新频率提高到8/5倍。
采用图13a所示的驱动方案驱动显示装置,4K的图像数据可以产生16个视点,同时实现20Hz的图像刷新率;采用图13b所示的驱动方案驱动显示装置,4K的图像数据可以产生4个视点,同时实现80Hz的图像刷新率。由此可见,当降低视点数量(降低图像分辨率)时,可以将节省的时间用于提高图像刷新率。
图14为本公开实施例提供的注视区域和非注视区域的充电电压对比图。
如图14所示,当栅极驱动单元输出扫描信号G的有效电平时段结束时,子像素的充电动作结束,然而由于本公开实施例对非注视区域的多列子像素同时充电,从图14中可以看出,四列子像素同时充电后的充电电压(4p)相比于各列子像素依次充电后的充电电压(1p)要更低,这是因为同时对四列子像素进行充电时产生的负载更大,那么采用同样的驱动电流同时驱动四列子像素充电会造成四列子像素充电不足,即采用相同的驱动电流对注视区域和非注视区域的子像素进行充电时,会造成非注视区域充电不足导致画面显示不均的问题。
本公开实施例为了克服上述问题,对驱动芯片的驱动电流进行调整,提高驱动芯片对非注视区域的驱动电流,以使注视区域和非注视区域内的子像素的充电程度的差值小于设定阈值,该设定阈值可以设置为一较小值,从而 使注视区域和非注视区域内的子像素的充电程度趋于相等。例如,在确定出注视区域和非注视区域之后,可以将注视区域的驱动电流调整为原本驱动电流的60%-80%,将非注视区域的驱动电流调整为原本驱动电流的100%-120%对显示装置进行驱动,以使注视区域和非注视区域内的子像素均能够充电充足,避免画面显示不均的问题。
具体地,控制器可以根据CHPI协议向驱动芯片的偏置电路连接的寄存器发送控制指令,以使驱动芯片可以区分注视区域和非注视区域采用寄存器中存储的驱动电流分别对注视区域和非注视区域进行驱动。
本公开实施例提供的显示装置还可以采用第二多路复用单元52进行驱动。具体的驱动电路可以采用7所示的结构。图15a为本公开实施例提供的注视区域对应的驱动时序图之三,图15b为本公开实施例提供的非注视区域对应的驱动时序图之三。
如图7所示,显示装置的栅极驱动电路包括多个栅极驱动单元(811-816),各栅极驱动单元分别向对应的子像素行输出扫描信号。每个像素岛与第一多路复用单元51和第二多路复用单元52的连接关系与图5相同,在此不做赘述。
如图15a和图15b所示,当采用第二多路复用单元52驱动显示装置时,控制信号线始终输出低电平(SWa),从而使得控制开关晶体管Tc保持关闭状态,此时信号无法传输到第一多路复用单元51,通过第二多路复用单元52控制图像数据的传输。采用第二多路复用单元52驱动显示装置,不仅可以将图像数据依次传输给多个像素岛,还可以将相同的图像数据同时传输给多个像素岛。
如图15a所示,在驱动相邻的多个像素岛20加载相同的图像数据时,控制各第二开关控制信号线同时输出有效电平信号(SWO和SWE为高电平信号),以使第二多路复用单元中的各第二开关晶体管T2同时打开;与此同时,控制第n行子像素连接的栅极驱动单元和第n+3行子像素连接的栅极驱动单元的输出信号相同;其中,n为大于或等于1的整数。
具体来说,在驱动两行两列的四个相邻的像素岛20加载相同的图像数据时,当第一条栅线输出扫描信号G1为有效电平时段(高电平时段)时,第四条栅线输出的扫描信号G4与G1相同,其它栅线输出扫描信号为低电平。各栅线保持有效电平的时长为1t。
在第一条栅线和第四条栅线输出有效电平时段期间,两条第二开关控制信号线均输出高电平信号(SWO和SWE均为高电平),此时控制上述四个像素岛的32个第二开关晶体管T2全部打开。图像数据可以同时传输给四个像素岛,且四个像素岛加载的图像数据相同,那么四个像素岛可以被当作一个大的像素岛使用,从而降低整体分辨率。上述驱动方法可以应用于非注视区域进行低分辨率的图像显示。
与此同时,如图15a所示,还可以控制四条第三开关控制信号线均输出高电平信号(SWb-SWe均为高电平),此时每个第三开关晶体管组T3s中的四个第三开关晶体管T3同时打开,同时为每个像素岛中的四列子像素同时传输相同的数据信号,这样可以进一步降低像素岛产生的视点数量,即减小像素岛内的分辨率,上述驱动方法可以应用于非注视区域进行低分辨率的图像显示。
在完成上述图像数据的传输之后,第一条栅线输出扫描信号G1为有效电平时段结束,第二条栅线输出扫描信号G2变为有效电平(高电平),第五条栅线输出的扫描信号G5与G2相同,各第二多路复用单元重复上述操作,以此类推,实现非注视区域的低分辨率的图像显示。
如图15b所示,在驱动各像素岛加载不同的图像数据时,控制各第二开关控制信号线依次输出有效电平信号(高电平信号),以使第二多路复用单元中的连接不同像素岛的第二开关晶体管依次打开,用于传输不同的图像数据。
具体来说,当第一条栅线输出扫描信号G1为有效电平时段(高电平时段)时,第四条栅线输出的扫描信号G4与G1相同;第二条栅线输出的扫描信号G2的有效电平时段相对于G1错后1t,第五条栅线输出的扫描信号与G2相同;以此类推。每条栅线保持高电平的时长为四列子像素依次进行充电所需 要的时长(保持高电平的时长为4t)。
在第一条栅线输出有效电平时段期间,第四条栅线输出的信号与第一栅线相同,两条第二开关控制信号线依次输出有效电平信号,即第一条第二开关控制信号线先输出高电平信号(SWO为高电平),第二条第二开关控制信号线输出低电平信号(SWE为低电平),而后第二条第二开关控制信号线输出有效电平信号(SWE高电平信号),第一条第二开关控制信号线输出低电平信号(SWO为低电平);其中每条第二开关控制信号线输出有效电平的时长为一列子像素进行充电所需要的时长(有效电平时长为1t)。此时,连接第一个像素岛的16个第二开关晶体管T2在第一条第二开关控制信号线的控制下打开时,连接第二个像素岛的16个第二开关晶体管T2在第二条开控制信号线的控制下关闭;连接第二个像素岛的16个第二开关晶体管T2在第二条第二开关控制信号线的控制下打开时,连接第一个像素岛的16个第二开关晶体管T2在第一条开控制信号线的控制下关闭,由此实现依次向各像素岛加载图像数据。
如图15b所示,在各第二开关晶体管T2进行上述驱动的同时,四条第三开关控制信号线依次输出有效电平信号(高电平信号),每条第三开关控制信号线保持高电平信号的时长为2t。
当第一条第三开关控制信号线输出有效电平信号(SWb为高电平)时,其它三条第三开关控制信号线均输出低电平信号(SWc-SW4e为低电平),此时只有连接第一条第三开关控制信号线的第三开关晶体管打开,驱动芯片输出的图像数据通过第一个第三开关晶体管传输给第一个像素岛的第一列子像素,驱动芯片输出的图像数据再通过第一个第三开关晶体管传输给第二个像素岛的第一列子像素。而后第二条第三开关控制信号线输出高电平信号(SWc为高电平),其它三条第三开关控制信号线均输出低电平信号(SWb、SWd、SWe为低电平),此时只有连接第二条第三开关控制信号线的第三开关晶体管打开,驱动芯片输出的图像数据通过第二个第三开关晶体管传输给第一个像素岛的第二列子像素,驱动芯片输出的图像数据再通过第二个第三开关晶体 管传输给第二个像素岛的第二列子像素。而后第三条第三开关控制信号线输出高电平信号(SWd为高电平),其它三条第三开关控制信号线均输出低电平信号(SWb、SWc、SWe为低电平),此时只有连接第三条第三开关控制信号线的第三开关晶体管打开,驱动芯片输出的图像数据通过第三个第三开关晶体管传输给第一个像素岛的第三列子像素,驱动芯片输出的图像数据再通过第三个第三开关晶体管传输给第二个像素岛的第三列子像素。而后第四条第三开关控制信号线输出高电平信号(SWe为高电平),其它三条第三开关控制信号线均输出低电平信号(SWb-SWd为低电平),此时只有连接第四条第三开关控制信号线的第三开关晶体管打开,驱动芯片输出的图像数据通过第四个第三开关晶体管传输给第一个像素岛的第四列子像素,驱动芯片输出的图像数据再通过第四个第三开关晶体管传输给第二个像素岛的第四列子像素。由此实现对不同像素岛的各子像素依次加载不同的图像数据的目的,上述驱动方法可以用于驱动注视区域进行高清图像显示。
采用图15a所示的驱动方案驱动显示装置,2K的图像数据可以产生4个视点,同时实现80Hz的图像刷新率;采用图15b所示的驱动方案驱动显示装置,2K的图像数据可以产生16个视点,同时实现80Hz的图像刷新率。由此可见,通过同时控制多个像素岛同时进行充电,也可以做到对视点数量的调整。
图16为本公开实施例提供的显示装置的***架构示意图。
如图16所示,在用户选择的2D显示模式时,接收2D视频源的图像数据;在用户选择3D显示模式时,接收3D视频源的图像数据。摄像头实时监测人眼的位置,从而确定出人眼在显示装置的注视点坐标以及分析出观看显示装置的人数。在确定出人眼在显示装置的注视位置之后将显示图像拆分为注视区域和非注视区域,并根据用户的选择模式对注视区域进行高分辨率的图像渲染,对非注视区域进行低分辨率的图像渲染,再将图像渲染后的图像数据发送给显示面板的驱动芯片,从而使显示面板根据指令进行驱动。与此同时,可以控制液晶透镜加载相适应的扫描驱动信号,从而在注视区域进行 高分辨率的图像显示,在非注视区域进行低分辨率的图像显示,由此在保证用户体验的前提下降低功耗,达到资源的合理分配。
上述数据处理和发送指令的操作均由本公开实施例的控制器实现,控制器可以为显示芯片(Graphics Processing Unit,简称GPU)和/或现场可编程门阵列(Field-Programmable Gate Array,简称FPGA),在此不做限定。
