Description

显示面板、显示装置及显示装置的驱动方法 技术领域
本公开涉及显示技术领域,尤其涉及一种显示面板、显示装置及显示装置的驱动方法。
背景技术
随着显示技术的不断发展,三维(three dimensional,3D)显示技术越来越备受关注。三维显示技术可以使显示画面变得立体逼真。其原理在于:利用人的左右眼分别接收具有一定视差的左眼图像和右眼图像,当两幅视差图像分别被人的左右眼接收后,经过大脑对图像信息进行叠加融合,可以构建出3D的视觉显示效果。
为实现超多视点3D显示和光场显示兼容,将传统亚像素做成像素岛结构,每个像素岛包含多个子像素,当多个子像素的显示信息均不同时,可实现光场3D显示;将多个子像素分组,每组子像素合并显示时,可实现超多视点3D显示。但现有技术中,每一组子像素合并显示仅能设置为显示信息相同,即只能实现像素岛中的每组子像素固定合并显示,当人眼位置改变时,合并显示子像素无法随之改变。

本公开实施例提供了一种显示面板,如图1所示,显示面板包括:
衬底基板1;包括显示区2以及位于显示区2之外的周边区3;
多条数据线4,位于衬底基板1的一侧,从显示区2延伸到周边区3;每一数据线4沿第一方向Y延伸,多条数据线4沿第二方向X排列;第一方向Y和第二方向X交叉;
多条扫描线5,与数据线4位于衬底基板1的同一侧;扫描线5沿第二方向X延伸,多条扫描线5沿第一方向Y排列;
多个子像素6,分别位于多条扫描线5和多条数据线4划分的区域内;沿第一方向Y和第二方向X相邻的至少两个子像素6构成一个像素岛7;在第二方向X上任意相邻的两个子像素6的发光颜色相同;
多条数据选择控制线MU,在周边区3与数据线4位于衬底基板1的同一侧;
多条数据输入线D,在周边区3与数据选择控制线MU位于衬底基板1的同一侧;
多个数据选择电路8,在周边区3与数据选择控制线MU位于衬底基板1的同一侧;每一数据选择电路8包括至少两个多路选择器9;每一数据选择电路8中,不同多路选择器9的输入端与不同数据输入线D耦接,不同多路选择器9的控制端与不同数据选择控制线MU耦接,不同多路选择器9的第i输出端与同一条数据线4耦接,其中,i为正整数;相邻两个数据选择电路8中,与不同数据选择控制线MU耦接的两个多路选择器9与同一数据输入线D耦接;数据选择电路8用于:在多条数据选择控制线MU的信号的控制下,将对应的数据输入线D的信号分别提供给耦接的每一条数据线4。
本公开实施例提供的显示面板,利用数据选择电路将数据输入线的信号提供给数据线,这样可以使得数据输入线的数量小于数据线的数量,从而可以减少数据输入量。并且本公开实施例提供的显示面板中的每一数据选择电路中包括至少两个多路选择器,且每一数据选择电路中的不同多路选择器与不同数据输入线耦接,这样,对于一个数据选择电路,在多条数据选择控制线的信号的控制下,可以将同一数据输入线的信号分别提供给耦接的每一条数据线,也可以将不同数据输入线的信号通过不同多路选择器分别提供给相应的数据线。即与同一数据选择电路连接的多条数据线可以输入相同的数据信号,也可以输入不完全相同的数据信号。当将每一像素岛中需要同一行的多个子像素合并显示时,当人眼位置发生改变时,合并显示子像素也发生改变,通过本公开实施例提供的显示面板的数据选择电路,便可以使得合并显示子像素的显示信息随之改变,可以使得子像素的显示信息随人眼移动而平滑过渡,提高显示效果,提升用户体验。

每一多路选择器9包括f个输出端、f个输入端以及f个控制端。
这样,对于一个子像素行中的每一子像素组,在多条数据选择控制线的信号的控制下,可以将同一数据输入线的信号通过与其对应的数据选择电路分别提供给与其耦接的每一条数据线,也可以将不同数据输入线的信号通过与其对应的数据选择电路分别提供给与其耦接的每一条数据线。即一个子像素组中各子像素可以通过数据选择电路输入相同的显示信息,也可以通过数据选择电路输入不完全相同的显示信息。

在一些实施例中,第一晶体管和第二晶体管均为P型晶体管或均为N型晶体管。这样,便于利用数据选择控制线对数据选择电路进行控制。
当然也可以是第一晶体管和第二晶体管中的一种为P型晶体管,另一中N型晶体管。
在一些实施例中,显示面板包括2f条数据选择控制线。

需要说明的是g为大于等于2且小于f的整数。当g等于2时,即每一子像素组中的第2个子像素至第f个子像素的显示信息相同,且第2个子像素至第f个子像素的显示信息与第1个子像素的显示信息不相同。
在具体实施时,当确定当前显示模式为第二显示模式时,且当用户眼睛移动,相对于图3向右移动一个子像素,即g=2,视点P与子像素对应情况例如可以是如图4所示,相应的时序图如图10所示,图10中,di代表像素岛中的第i个视点Pi的显示信息对应的数据信号。即D0依次输入d4、d1数据信号,D1依次输入的d1、d2数据信号,D2依次输入d2、d3数据信号,D3依次输入的d3、d4数据信号,D4依次输入的d4、d1数据信号。向MU1提供第一数据选择控制信号、之后向MU3、MU5、MU7同时提供第一数据选择控制信号,以控制每一数据选择电路8中的T11先开启、之后T12、T13、T14同时开启。同时向MU2、MU4、MU6、MU8提供第二数据选择控制信号,以控制每一数据选择电路8中的四个第二选择开关T21、T22、T23、T24关断。这样,便可以实现图4对应的合并显示方案。

在一些实施例中,当确定当前显示模式为第二显示模式时,根据显示信息,向数据选择控制线提供数据选择控制信号,通过数据选择电路,将数据写入线提供的与显示信息对应的数据信号提供给与注视区域的像素岛对应的每一条数据线,还包括:

本公开实施例提供的显示装置的驱动方法,当人眼位置发生改变时,不仅可以使得子像素的显示信息随人眼移动而平滑过渡,提高显示效果,提升用户体验。如图12、图13所示,利用数据选择电路中的多组数据选择器实现将不同数据信号通过数据选择器提供给一个子像素组,在第二显示模式下无需提高显示装置的刷新频率,在显示装置的系统资源不足的情况下,可以节约显示装置功耗。
需要说明的是,图8~图13中,控制选择开关开启的第一数据选择控制信号为高电平信号,控制选择开关关断的第二数据选择控制信号为低电平信号。
综上所述,本公开实施例提供的显示面板、显示装置及其驱动方法,利用数据选择电路将数据输入线的信号提供给数据线,这样可以使得数据输入 线的数量小于数据线的数量,从而可以减少数据输入量。并且本公开实施例提供的显示面板中的每一数据选择电路中包括至少两个多路选择器,且每一数据选择电路中的不同多路选择器与不同数据输入线耦接,这样,对于一个数据选择电路,在多条数据选择控制线的信号的控制下,可以将同一数据输入线的信号分别提供给耦接的每一条数据线,也可以将不同数据输入线的信号通过不同多路选择器分别提供给相应的数据线。即与同一数据选择电路连接的多条数据线可以输入相同的数据信号,也可以输入不完全相同的数据信号。当将每一像素岛中需要同一行的多个子像素合并显示时,当人眼位置发生改变时,合并显示子像素也发生改变,通过本公开实施例提供的显示面板的数据选择电路,便可以使得合并显示子像素的显示信息随之改变,可以使得子像素的显示信息随人眼移动而平滑过渡,提高显示效果,提升用户体验。
