具体实施方式
为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施方式作进一步地详细描述。
显示装置在显示时,画面中的一些区域可能由于各种原因而显示异常,如图1所示,图1是一种显示装置的显示画面的示意图,该显示画面为白色画面,但该白色画面中包括多个显示异常区域m1。此时就需要对显示装置进行补偿,以降低显示异常的影响。
显示装置中可以包括多种颜色的子像素,如红色子像素、绿色子像素以及蓝色子像素等,目前的显示装置的补偿设备在进行补偿时,会分别对不同颜色的画面进行补偿,当各个颜色的画面都进行补偿后,即可以降低甚至效果显示异常的影响。
示例性的,在对红色画面进行补偿时,可以控制显示装置显示红色画面,并通过显示装置的补偿设备中的摄像头拍摄该红色画面,得到拍摄图像,示例性的,如图2所示,图2是一种拍摄图像的示意图,由图2可以看出,除了与图1中类似的几个显示异常区域m2外,该拍摄图像的左右边缘还具有偏色的异常区域m3。显示装置的补偿设备中的处理器可以获取该拍摄图像的中央区域311的亮度均值,并以该亮度均值来确定显示装置的显示画面上所有待补偿区域(每个待补偿区域可以是显示画面中的一个小区域)的补偿数据,再确定显示画面所有区域的补偿数据后,可以将补偿数据输入显示装置,显示装置基于该补偿数据进行补偿后,显示红色画面的拍摄图像可以如图3所示,图3是另一种拍摄图像的示意图,可以看出,经过补偿之后,该图像31中各个区域的亮度基本一致。但是,此种补偿方式中,始终会以显示画面中固定的中央区域的亮 度均值来确定补偿数据,使得该方式的灵活性较差。另外,若该中央区域存在较大的显示异常区域,则会导致整个显示画面的补偿效果较差。
本申请实施例提供了一种显示装置的补偿设备、方法、显示装置及计算机存储介质,可以解决上述相关技术中存在的一些问题。
图4是本申请实施例示出的一种显示装置的补偿设备的结构示意图,图5是本申请实施例中一种第一图像的示意图,请参考图4以及图5,该显示装置的补偿设备40包括图像获取组件41以及控制组件42。
图像获取组件41用于获取显示装置显示第一色的画面时的第一图像,显示装置中包括用于发出第一色的光束的子像素。
控制组件42用于基于第一图像中第一待补偿区域q1在第一方向f1上的位置,确定在第一图像中的第一参考区域q2,第一参考区域q2在第一方向f1上的位置与第一待补偿区域q1相同,第一参考区域q2大于第一待补偿区域q1。
控制组件42用于基于第一参考区域q2的亮度均值以及第一待补偿区域q1的亮度均值确定第一待补偿区域的补偿数据。
其中,控制组件42所确定的补偿数据,可以用于使显示装置对显示画面中第一待补偿区域对应的区域进行调节,以使第一待补偿区域的亮度与第一参考区域的亮度均值一致。
另外,上述第一待补偿区域q1可以是第一图像中的任一区域,控制组件42依次将第一图像中的部分或全部区域分割为多个第一待补偿区域,并通过上述方式确定每个第一待补偿区域的补偿数据。
图像获取组件41可以包括摄像头,该摄像头可以拍摄显示装置显示图像的一面,并将拍摄得到的图像传输至控制组件42。当然,该图像获取组件41还可以通过其他方式来获取第一图像,如通过数据传输的方式等,本申请实施例对此不进行限制。
综上所述,本申请实施例提供的显示装置的补偿设备,通过控制组件基于第一待补偿区域在第一方向上的位置,确定在图像获取组件获取的第一图像中的第一参考区域,之后控制组件便可以基于第一参考区域的亮度均值以及第一待补偿区域的亮度均值确定第一待补偿区域的补偿数据,后续显示装置在显示时可以基于该补偿数据对第一待补偿区域进行补偿,由于第一参考区域在第一 方向上的位置与第一待补偿区域相同,进而第一参考区域的位置就可以随第一待补偿区域的位置的不同而变化,提高了该补偿设备的灵活性。
另外,相对于相关技术中固定位置的参考区域,本申请提供的显示装置的补偿设备在确定补偿数据时,所参考的第一参考区域的位置与第一待补偿区域的位置相关,也即是在对不同位置的第一待补偿区域进行补偿时,所参考的第一参考区域的亮度均值也可能不同,且该亮度均值是与第一待补偿区域的位置相关的,如此便提升了补偿数据与第一待补偿区域的关联性。
需要说明的是,第一图像可以为拍摄显示装置的显示画面显示第一色的画面所得到的图像,该第一图像可以与显示装置的显示画面具有相同的形状(可以通过控制拍摄角度或者裁切的方式来使第一图像和显示画面的形状一致),对应的,第一图像中的各个位置(或区域)以及与显示画面中的各个位置(或区域)也是对应的,示例性的,第一图像和显示画面可以具有同样的坐标系,在第一图像中确定了一个位置的坐标后,基于该坐标即可以在显示画面上确定对应的位置。
在此基础上,当上述显示装置的补偿设备获取了第一待补偿区域的补偿数据后,便可以将该补偿数据写入显示装置中,显示装置可以基于该补偿数据,对第一待补偿区域在显示画面中对应的区域进行补偿。
另外,由于第一参考区域q2大于第一待补偿区域q1,进而本申请实施例所述的第一参考区域q2在第一方向f1上的位置与第一待补偿区域q1相同,可以是指在第一待补偿区域q1至少位于第一参考区域q2第一方向f1上的两个极值点所划定的区域内,如图5所示,该两个极值点可以是指第一参考区域q2在第一方向f1上最右侧的点以及最左侧的点,这两个极值点所划定的区域可以是指分别经过这两个极值点且垂直于第一方向f1的两条线所划定的区域。
还需要说明的是,本申请实施例中所述的某个区域的亮度均值,可以是指该区域中所有像素的亮度的平均值,该平均值可以为算术平均值、几何平均值或者其他类型的平均值,本申请实施例对此不进行限制。
在一种示例性的实施例中,显示装置中可以包括横纵排布的多列像素,每个像素可以包括R(红色子像素)、G(绿色子像素)以及B(蓝色子像素)这 三类子像素,其中的红色子像素和蓝色子像素可能会与同一根源极走线连接,再加上显示面板的扇出区(Fan out)中边缘的走线较长,负载较大的原因,可能会导致显示画面边缘区域对应的子像素的充电时间不够(该问题在高刷新率的显示装置汇总尤为严重),并导致显示面板显示红色画面和蓝色画面时,边缘区域的亮度较低,如图6所示,图6是一种显示装置显示红色画面的示意图,其中,边缘区域61的亮度低于其他区域。
但是,如图7所示,图7是一种显示装置显示白色画面的示意图,显示装置在显示白色画面(显示装置显示白色画面实质是同时点亮红色子像素、绿色子像素以及蓝色子像素)71时,红色子像素和蓝色子像素所连接的同一根源极走线会来回切换对红色子像素和蓝色子像素充电,充电时间基本可以满足要求,进而在显示白色画面时,边缘不会出现偏色等显示异常。
如此便出现了部分纯色画面的边缘会出现偏色等显示异常,但白色画面又不会出现偏色等显示异常的情况。此种情况下,若应用上述相关技术中的补偿方式,则显示装置在显示白色画面时,则边缘可能会出现偏色异常,如此便使得上述的显示装置的补偿设备的补偿效果较差。示例性的,图8是一种显示装置补偿后显示白色画面的示意图,其中,边缘存在偏色异常区域81。
本申请实施例提供的显示装置的补偿设备可以解决该问题。
在一种示例性的实施例中,请参考图5。第一图像呈矩形,且第一图像的两个相对的边缘(b1和b2)中的至少一个边缘所在的位置处包括显示异常区域q3(图5示出的是两个边缘b1和b2均包括显示异常区域的情况,但本申请实施例对此并不进行限制),另外,该第一图像中还包括多个其他显示异常区域q4,第一方向f1为与两个相对的边缘(b1和b2)垂直的方向。针对此种情况,本申请实施例提供的显示装置的补偿设备中,控制组件在确定与显示异常区域q3存在重叠的第一待补偿区域的补偿数据时,便会基于与显示异常区域q3存在重叠的第一参考区域q2的亮度均值来确定补偿数据,进而便可以在降低其他显示异常区域q4的影响下,不对该边缘的显示异常q3进行亮度的调节,进而在显示装置显示白色画面时,便不会出现边缘偏色的问题。
当第一方向f1为横向时,本申请实施例提供的显示装置的补偿设备便可以解决显示装置的显示画面左右两侧存在偏色(如偏红或偏绿等)的问题,当第一方向f1为纵向时,本申请实施例提供的显示装置的补偿设备便可以解决显示装置的显示画面上下两侧存在偏色的问题。
本申请实施例中,控制组件可以通过至少四种方式来确定第一参考区域,下面分别进行说明。
第一种方式:请参考图8,图8是本申请实施例中另一种第一图像的示意图,控制组件,还用于:
确定第一待补偿区域q1在第一方向f1上的第一坐标,第一坐标所在坐标系的一个坐标轴与第一方向f1平行。
当第一待补偿区域q1在第一方向f1上与第一图像的边缘之间的距离s1大于或者等于指定距离s2时,以第一坐标作为第一参考区域q2在第一方向f1上的中心坐标,确定第一参考区域q2。第一参考区域q2可以具有预设尺寸(也即是预先设置的尺寸),指定距离s2为预设尺寸的第一参考区域q2在第一方向f1上长度的二分之一。图8中的z1可以为第一参考区域q2的几何中心。
请参考图9,图9是本申请实施例中另一种第一图像的示意图,当第一待补偿区域q1在第一方向f1上与第一图像的边缘之间的距离s1小指定距离s2时,将与边缘贴合且具有预设尺寸的区域确定为第一参考区域q2。
如此方式下,便可以提升第一待补偿区域q1在第一方向f1上的位置,与第一参考区域q2的关联度。
另外,该方式为一种确定第一参考区域q2的方式,在本申请实施例中,可以认为确定的第一参考区域q2为与第一待补偿区域q1对应的区域,每个第一待补偿区域q1均可以与一个第一参考区域q2对应。
在一种示例性的实施例中,第一参考区域q2在第一方向f1上的长度范围为a/10至a/5,a为第一图像在第一方向f1上的长度。该长度范围下,可以使得第一参考区域q2在合适的尺寸下,为第一待补偿区域q1的亮度提供参考。
请参考图8,第一参考区域q2的中心z1在第二方向f2上位于第一图像的中心,第二方向f2为与第一方向f1垂直的方向。由于显示画面边缘出现异常的概率可能大于中央出现异常的概率,进而当第一参考区域q2的中心z1在第二方向f2上位于第一图像的中心时,可以提升基于该第一参考区域q2的亮度均值确定的补偿数据的补偿效果,进而提升显示装置的显示效果。
可选地,第一参考区域q2在第二方向f2上的长度范围为b/10至b/5,b为第一图像在第二方向f2上的长度,第二方向f2为与第一方向f1垂直的方向。该长度范围下,可以使得第一参考区域q2在合适的尺寸下,为第一待补偿区域 q1的亮度提供参考。
当然,本申请实施例中,第一参考区域的中心还可以在其他位置,示例性的,请参考图10,图10是本申请实施例中另一种第一图像的示意图,其中,第一参考区域q2的中心z1在第二方向f2上位于第一图像的中心z2(该中心可以为第一图像的几何中心或重心)和第一待补偿区域q1之间,第二方向f2为与第一方向f1垂直的方向。
请参考图11,图11是本申请实施例中另一种第一图像的示意图,其中,第一参考区域q2的中心z1在第二方向f2上位于第一图像的中心远离第一待补偿区域q1的一侧。
第二种方式:请参考图12,图12是本申请实施例中另一种第一图像的示意图,控制组件,还用于:
基于第一待补偿区域q1在第一方向f1上的位置,确定第一待补偿区域q1所在的条状区域tq,第一图像包括沿第一方向f1排布的多个条状区域tq,每个条状区域tq中具有一个参考区域cq。
将第一待补偿区域q1所在的条状区域tq中的参考区域cq确定为第一参考区域q2。
此种方式中,控制组件预先在第一图像中确定了多个条状区域tq,以及每个条状区域tq中的参考区域cq,之后根据第一待补偿区域q1所在的条状区域tq,便可以确定第一参考区域q2。
与上一种确定第一参考区域的方式类似,图11所示的确定第一参考区域的方式中,第一参考区域在第二方向上也可以位于各种位置,例如,第一参考区域的中心在第二方向上位于第一图像的中心。
或者,第一参考区域的中心在第二方向上位于第一图像的中心和第一待补偿区域之间,第二方向为与第一方向垂直的方向;
或者,第一参考区域的中心在第二方向上位于第一图像的中心远离第一待补偿区域的一侧。
第三种方式:请参考图13,图13是本申请实施例中另一种第一图像的示意图,控制组件,还用于:
基于第一待补偿区域q1在第一方向f1以及第二方向f2上的位置,确定在 第一图像中的第一参考区域q2,第二方向f2为与第一方向f1垂直的方向,第一参考区域q2在第一方向f1以及第二方向f2上的位置与第一待补偿区域q1相同。此种情况下,第一参考区域q2可以是一个始终包围第一待补偿区域的区域。
此种方式确定的第一参考区域q2,可以用于解决显示装置的显示画面的四个边缘均存在色偏以及亮度差异的问题。此类问题可能出现在大尺寸的显示装置中,本申请实施例提供的显示装置的补偿装置可以用于解决此类问题。
在一种示例性的实施例中,控制组件,还用于:
确定第一待补偿区域q1在第一方向f1上的第一坐标以及在第二方向f2上的第二坐标(示例性的,第一坐标可以为x坐标,第二坐标可以为y坐标),第一坐标以及第二坐标所在坐标系的一个坐标轴(例如可以是x轴)与第一方向f1平行,另一个坐标轴(例如可以是y轴)与第二方向f2平行。
基于第一坐标以及第二坐标,将第一图像中,中心与第一待补偿区域最近且具有预设尺寸的参考区域确定为第一参考区域q2,该预设尺寸为预先设置的第一参考区域q2的尺寸。
中心与第一待补偿区域q1最近且具有预设尺寸的参考区域可以包括两种情况,一种情况中,请参考图14,图14是本申请实施例中另一种第一图像的示意图,其中,第一待补偿区域q1与第一图像在第一方向f1上的两个边(即左右两个边)之间的距离均大于或等于第一参考区域q2在第一方向f1上的长度的一半,且第一待补偿区域q1与第一图像在第二方向f2上的两个边(即上下两个边)之间的距离均大于或等于第一参考区域q2在第一方向f1上的长度的一半,此种情况下,第一参考区域q2的位置(第一参考区域q2的位置可以是指第一参考区域q2的几何中心z1的位置)与第一待补偿区域q1的中心z3重合(第一参考区域q2的中心z1与第一待补偿区域q1的距离为零)。
另一种情况中,请参考图15,图15是本申请实施例中另一种第一图像的示意图,第一待补偿区域q1与第一图像在第一方向f1上的一条边之间的距离小于第一参考区域q2在第一方向f1上的长度的一半,和/或,第一待补偿区域q1与第一图像在第二方向f2上的一条边之间的距离小于第一参考区域q2在第一方向f1上的长度的一半,此种情况下,第一参考区域q2的中心z1可以尽可能的接近第一待补偿区域q1的中心z3。
第四种方式:请参考图16,图16是本申请实施例中另一种第一图像的示意 图,控制组件,还用于:
确定第一待补偿区域q1在第一方向f1上的第一坐标以及在第二方向f2上的第二坐标(示例性的,第一坐标可以为x坐标,第二坐标可以为y坐标),第一坐标以及第二坐标所在坐标系的一个坐标轴(如x轴)与第一方向f1平行,另一个坐标轴(如y轴)与第二方向f2平行。第一待补偿区域q1的坐标可以是指第一待补偿区域q1中的一个点的坐标,该点可以为中心z3,或者是其他位置的点(如边缘的顶点等)。
基于第一坐标以及第二坐标,确定第一待补偿区域q1所在的块状区域kq,第一图像包括沿第一方向f1以及第二方向f2横纵排布的多个块状区域kq。
将第一待补偿区域q1所在的块状区域kq确定为第一参考区域q2。
与上述第二种方式类似,此种方式是预先将第一图像划分为多个块状区域kq,之后基于第一待补偿区域q1的横纵坐标来确定第一待补偿区域q1所位于的块状区域kq,之后可以将第一待补偿区域q1所位于的块状区域kq确定为第一参考区域q2。本方案可以与第三种方案类似,用于解决显示装置的显示画面的四个边缘均存在色偏以及亮度差异的问题。
显示装置显示的显示画面中可以包括多个第一待补偿区域,本申请实施例中,控制组件可以通过上述至少一种方式来确定这多个第一待补偿区域对应的第一参考区域。
综上所述,本申请实施例提供的显示装置的补偿设备,通过控制组件基于第一待补偿区域在第一方向上的位置,确定在图像获取组件获取的第一图像中的第一参考区域,之后控制组件便可以基于第一参考区域的亮度均值以及第一待补偿区域的亮度均值确定第一待补偿区域的补偿数据,后续显示装置在显示时可以基于该补偿数据对第一待补偿区域进行补偿,由于第一参考区域在第一方向上的位置与第一待补偿区域相同,进而第一参考区域的位置就可以随第一待补偿区域的位置的不同而变化,提高了该补偿设备的灵活性。
另外,本申请实施例提供的显示装置的补偿设备,可以应用于对高刷新率(如刷新率大于或等于60赫兹的显示装置)的显示装置进行补偿,以避免高刷新率的显示装置中出现偏色等显示异常的问题。
图17是本申请实施例提供的一种显示装置的结构示意图,该显示装置170包括:显示面板171以及控制组件172。
显示面板171中包括用于发出第一色的光束的子像素。
控制组件172用于获取第一待补偿区域的补偿数据,补偿数据是获取显示装置显示第一色的画面时的第一图像后,基于第一图像中第一待补偿区域在第一方向上的位置,确定在第一图像中的第一参考区域,并基于第一参考区域的亮度均值以及第一待补偿区域的亮度均值确定的补偿数据,第一参考区域在第一方向上的位置与第一待补偿区域相同,第一参考区域大于第一待补偿区域;
控制组件172用于基于补偿数据对显示面板的显示画面的第一待补偿区域进行补偿。
综上所述,本申请实施例提供的显示装置,基于补偿数据对显示面板的显示画面的第一待补偿区域进行补偿,且该补偿数据是基于第一参考区域的亮度均值以及第一待补偿区域的亮度均值确定第一待补偿区域的补偿数据,且由于第一参考区域在第一方向上的位置与第一待补偿区域相同,进而第一参考区域的位置就可以随第一待补偿区域的位置的不同而变化,可以提升显示装置对第一待补偿区域进行补偿的灵活性。
对于显示装置中,显示画面的两个相对的边缘出现偏色的问题,一方面是由于扇出区不同位置的走线的长度不一致,进而导致不同走线的负载不同而引起的。在此基础上,本申请实施例提供的显示装置中,可以对扇出区的走线进行调整,以缩小扇出区的多条走线之间的负载差距,使源极走线的负载均一。
另外一方面是由于源极走线对于红色子像素和蓝色子像素的充电不足而引起的,在此基础上,本申请实施例提供的显示装置中,可以增加电容补偿,以保证对于红色子像素和蓝色子像素的充电效果。
图18是提供一种显示装置的补偿方法的方法流程图,该方法可以应用于上述实施例提供的显示装置的补偿设备中,该方法可以包括下面几个步骤:
步骤1801、获取显示装置显示第一色的画面时的第一图像,显示装置中包括用于发出第一色的光束的子像素。

步骤1803、基于第一参考区域的亮度均值以及第一待补偿区域的亮度均值确定第一待补偿区域的补偿数据。
可选地,第一图像呈矩形,且第一图像的两个相对的边缘中的至少一个边缘所在位置处包括显示异常区域,第一方向为与两个相对的边缘垂直的方向。
可选地,上述步骤1801可以包括:
确定第一待补偿区域在第一方向上的第一坐标,第一坐标所在坐标系的一个坐标轴与第一方向平行;
当第一待补偿区域在第一方向上与第一图像的边缘之间的距离大于或者等于指定距离时,以第一坐标作为第一参考区域在第一方向上的中心坐标,确定第一参考区域,第一参考区域具有预设尺寸,指定距离为预设尺寸的第一参考区域在第一方向上长度的二分之一;

可选地,上述基于第一待补偿区域在第一方向以及第二方向上的位置,确定在第一图像中的第一参考区域的步骤可以包括:

基于第一坐标以及第二坐标,将第一图像板中,中心与第一待补偿区域最近且具有预设尺寸的参考区域确定为第一参考区域,预设尺寸为预先设置的第一参考区域的尺寸。
可选地,上述基于第一待补偿区域在第一方向以及第二方向上的位置,确定在第一图像中的第一参考区域的步骤可以包括:
确定第一待补偿区域在第一方向上的第一坐标以及在第二方向上的第二坐标,第一坐标以及第二坐标所在坐标系的一个坐标轴与第一方向平行,另一个坐标轴与第二方向平行;

可选地,第一参考区域在第二方向上的长度范围为b/10至b/5,b为第一图像在第二方向上的长度,第二方向为与第一方向垂直的方向。
综上所述,本申请实施例提供的显示装置的补偿方法,通过基于第一待补偿区域在第一方向上的位置,确定在获取的第一图像中的第一参考区域,之后控制组件便可以基于第一参考区域的亮度均值以及第一待补偿区域的亮度均值确定第一待补偿区域的补偿数据,后续显示装置在显示时可以基于该补偿数据对第一待补偿区域进行补偿,由于第一参考区域在第一方向上的位置与第一待补偿区域相同,进而第一参考区域的位置就可以随第一待补偿区域的位置的不同而变化,提高了该补偿设备的灵活性。
另外,相对于相关技术中固定位置的参考区域,本申请提供的显示装置的补偿设备在确定补偿数据时,所参考的第一参考区域的位置与第一待补偿区域的位置相关,也即是在对不同位置的第一待补偿区域进行补偿时,所参考的第 一参考区域的亮度均值也可能不同,且该亮度均值是与第一待补偿区域的位置相关的,如此便提升了补偿数据与第一待补偿区域的关联性。
