具体实施方式
下面将结合本公开的实施例中的附图，对本公开的实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本公开的一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
除非上下文中另外明确地指出，否则在本文和所附权利要求中所使用的词语的单数形式包括复数，反之亦然。因而，当提及单数时，通常包括相应术语的复数。措辞“包含(comprise)”、“包含(include)”以及它们的语法变型将解释为包含在内而不是独占性地，除非本文中明确禁止这样的解释。在本文中使用术语“示例”之处，特别是当其位于一组术语之后时，所述“示例”仅仅是示例性的和阐述性的，且不应当被认为是独占性的或广泛性的。
本文中描述的单元或模块可以实现为处理器和存储器的组合，其中处理器执行存储器中存储的程序以实现相应单元或模块的功能。本文中描述 的单元或模块也可以完全的硬件实施方式实现，例如，包括专用集成电路(ASIC)、现场可编程门阵列(FPGA)等。替代地，本文描述的单元或模块还可以通过硬件和软件(和/或固件)的组合来实现。
图1(a)和图1(b)分别为液晶显示装置在L0和L255状态下液晶的示例的扭转状态。如图1(a)和1(b)所示，在L0状态下，液晶分子整齐排布；在L255状态下，液晶发生扭转。在L255状态下，针对不同视角，液晶所处的长短轴状态不同。图2为在L255状态下，针对不同视角，液晶的长短轴的示例状态。如图2所示，在可视角Φ＝90°和Φ＝270°时，液晶与正视角一样观察者观察到的是长轴状态，而在可视角Φ＝0°和Φ＝180°时，只能观察到液晶的短轴。由于侧视时液晶折射率(Δn)偏小，因此侧视时观看到的显示画面发生偏蓝现象。
如图3(a)和图3(b)分别为显示装置在为弯曲状态和弯曲状态下人眼视线与显示装置的夹角。如图3(a)所示，在显示装置尺寸较小的情况下，在显示装置没有弯曲时，人眼视线与显示装置的夹角都可以近似认为是90°。但是，如图3(b)所示，在显示装置弯曲状态下(图中以向观看侧凸起为例，当然也可能向背离观看侧的方向凸起)，人眼视线与显示装置中心位置的夹角为90°，而人眼视线与显示装置边缘位置的夹角小于90°。越远离中心位置，夹角越小。由于在弯曲状态下，对于从人眼朝向边缘位置的视线的角度而言，液晶的折射率较小，因而显示画面在边缘位置发生显示画面偏蓝的现象。通常，显示面板10的曲率半径越小，偏蓝现象越严重。
本公开的实施例提供一种显示装置。图4为本公开的实施例提供的一种显示装置的结构示意图。如图4所示，显示装置包括显示面板10、检测单元20和控制单元30。显示面板10沿观看水平方向被划分为n个区域，其中，n为正整数，且n≥2。检测单元20被配置为检测对应于n个区域中的每一个区域的观看视角。在示例的实施例中，观看视角为人眼视线与显示面板10的夹角。控制单元30被配置为根据观看视角调整以下中的一种或两种：i)显示面板10的观看视角所对应的区域的灰阶电压值，和ii)显示面板10的背光源对应于观看视角所对应的区域的部分的亮度。
如在此所使用的，术语“观看水平方向”指的是人眼在正视显示屏幕 时与两只眼睛之间的连线平行的方向。示例的，无论显示面板10是横屏显示，还是竖屏显示，观看水平方向都是眼在正视显示屏幕时与两只眼睛之间的连线平行的方向，如图5(a)和图5(b)中的箭头所示。
在本公开的实施例中，显示面板10沿观看水平方向可以被划分为2个区域、3个或3个以上区域。显示面板10沿水平方向被划分的区域越多，越能精确调整显示面板10显示的图像，使得显示画面更均匀。
当显示面板10为平面显示面板时，“人眼视线与显示面板10的夹角”可以指人眼与人眼在显示面板10上的注视点的连线(即，人眼视线)和显示面板10之间的夹角，如图6(a)所示。当显示面板10为曲面显示面板时，“人眼视线与显示面板10的夹角”可以指人眼与人眼在显示面板10上的注视点的连线(即，人眼视线)和显示面板10上人眼注视点的切线之间的夹角，如图6(b)所示。
在本公开的实施例中，对于显示装置的类型不进行限定，可以是液晶显示装置(Liquid Crystal Display，简称LCD)，也可以是有机电致发光二极管显示装置(Organic Light-Emitting Diode，简称OLED)。此外，本公开实施例的显示装置可以为可弯曲的柔性显示装置。
在显示装置为液晶显示装置的情况下，液晶显示装置可以例如包括液晶显示面板和背光源，背光源用于为液晶显示面板提供光源。当观看者侧视或液晶显示面板弯曲时，针对不同观看视角，液晶所处的长短轴状态不同，导致不同方向液晶的折射率不同，因此观看者看到的显示画面会出现画质不均匀(例如，色偏)的现象。在本公开的示例的实施例中，控制单元30可以根据检测单元20获得的观看视角对显示面板10的观看视角所对应的区域的灰阶电压值进行调整。在替代的实施例中，控制单元30可以根据检测单元20的获得的观看视角对显示面板10的背光源对应于观看视角所对应的区域部分的亮度进行调整。在另一替代的实施例中，控制单元30可以根据检测单元20的获得的观看视角对显示面板10观看视角所对应的区域的灰阶电压值和显示面板10的背光源对应于观看视角所对应的区域的部分的亮度均进行调整。
在显示装置为有机电致发光二极管显示装置的情况下，有机电致发光二极管显示装置可以包括阳极、阴极以及设置在阳极和阴极之间的有机层， 有机层用于发光。有机电致发光二极管显示装置的发射光谱受微腔效应影响较大。在观看者侧视或显示面板弯曲的情况下，由于对于侧视角和正视角的发射光谱不一样，以及弯曲部分和非弯曲部分的发射光谱不一样，因此观看者看到的显示画面会出现画质不均匀(例如，色偏)的现象。在这种情况下，控制单元30可以根据检测单元20获得的观看视角，对显示面板10的观看视角所对应的区域的灰阶电压值进行调整。
通过示例的方式，相应区域的灰阶电压值可以通过调整施加在数据线上的电压大小来实现。背光源的对应于相应区域的部分的亮度可以通过调整电流的大小来实现。
在显示装置为液晶显示装置的情况下，背光源可以是侧入式背光源，也可以是直下式背光源。在背光源是侧入式背光源的情况下，多个LED(Light Emitting Diode，发光二极管)可以沿观看水平方向依次排布。
在本公开的示例的实施例中，如上所述，控制单元30可以根据观看视角对显示面板10的观看视角所对应的区域的灰阶电压值和显示面板10的背光源对应于观看视角所对应的区域的部分的亮度中的一种或两种进行调整，因而可以对显示面板10显示的图像进行调整。作为示例，随着观看视角减小，控制单元30可以进行以下一种或两种操作：i)控制显示面板10的观看视角所对应的区域的灰阶电压值减小，和ii)控制显示面板10的背光源对应于观看视角所对应的区域的部分的亮度增大。通过对施加在显示面板10的灰阶电压值和背光源的亮度中的一种或两种的调整，可以避免在侧视时或显示面板10弯曲时，观看者看到的显示画面的画质不均匀(例如，色偏)，从而改善显示画面的品质。
在示例的实施例中，观看视角可以通过以下参数中的一种或两种来表征：i)观看位置到显示面板10的n个区域中的每一个区域的的距离，和ii)显示面板10在n个区域中的每一个区域的弯曲程度。
在该示例的实施例中，观看位置到显示面板10的n个区域的每一个区域的距离和显示面板10在n个区域的每个区域的弯曲程度均可以表征观看视角。作为示例，观看位置到显示面板10单独的区域的距离越大，观看视角越小；并且显示面板10的弯曲程度越大，观看视角越小。
在显示面板10为平面显示面板的情况下，由于平面显示面板的曲率为 零，观看视角仅与观看位置到显示面板10的各个区域的距离有关，因而可以仅通过观看位置到显示面板10的各个区域的距离来表征观看视角。在显示面板10为小尺寸曲面显示面板的情况下，例如，可穿戴眼镜或可穿戴头盔，可近似认为显示面板的各个区域到观看位置的光线都是平行的，即，观看位置到显示面板10的各个区域的距离不影响观看视角。在这种情况下，观看视角仅与显示面板10在各个区域的弯曲程度有关，因此可以仅通过显示面板10在各个区域的弯曲程度来表征观看视角。在显示面板10为大尺寸曲面显示面板的情况下，观看视角与观看位置到显示面板10的各个区域的距离和显示面板10在各个区域的弯曲程度均有关，因此可以通过观看位置到显示面板10的各个区域的距离和显示面板10在各个区域的弯曲程度来表征观看视角。
此处，弯曲程度例如可以通过曲率或曲率半径来表示。然而，这并不旨在将本公开的范围限制在弯曲程度的特定表示方式，本领域技术人员可以容易地认识到，当采用其他表示形式时如何适配相关的条件和设置。此外，本公开对于如何检测显示面板10在各个区域的弯曲程度不进行限定。作为示例，各个区域的弯曲程度可以通过曲率传感器进行检测。
类似地，本公开对于如何检测观看位置到显示面板10的各个区域的距离不进行限定。作为示例，该距离可以通过红外探测头进行检测。
在示例的实施例中，控制单元30可以被配置为通过如下一种或两种操作来进行调整：i)随着观看视角减小，减小显示面板10的观看视角所对应的区域的灰阶电压值；和ii)随着观看视角减小，增大显示面板10的背光源对应于观看视角所对应的区域的部分的亮度。
在显示面板10为液晶显示面板的情况下，随着观看视角减小，作为一个示例，控制单元30可以控制显示面板10的观看视角所对应的区域的灰阶电压值减小；作为另一示例，控制单元30可以控制显示面板10的背光源对应于观看视角所对应的区域的部分的亮度增大；作为又一示例，控制单元30可以控制显示面板10的观看视角所对应的区域的灰阶电压值减小，并且控制显示面板10的背光源对应于观看视角所对应的区域的部分的亮度增大。在显示面板10为有机电致发光二极管显示面板的情况下，随着观看视角减小，控制单元30可以控制显示面板10的观看视角所对应的区域 的灰阶电压值减小。
此处，对于相应区域的灰阶电压值的减小幅度和背光源的增大幅度可以根据观看视角的大小来确定，以使得通过控制单元30的调整后显示面板10显示的图像没有或具有较小的色偏。在本公开的示例的实施例中，灰阶电压值是在待显示图像的预定灰阶电压值的基础上进行减小。通过示例的方式，观看视角越小，灰阶电压值的减小的越多，并且背光源的亮度增大的越多。
以下结合具体的示例对本公开的实施例提供的显示装置进行说明。
以小尺寸液晶显示面板为例，显示面板可以具有以下参数或设定：显示面板的尺寸为8×20cm 2；显示面板的背光为长边侧入光；作为光源的LED的数量为10颗；如图7所示，沿观看水平方向将显示面板分为5个区域(D1～D5)；以及对于平面(即，非弯曲的)液晶显示面板，在显示L255时，显示面板在D1～D5区域的色坐标相同，例如，均为(0.30，0.32)(本公开的实施例的色坐标均是在CIE1931坐标系下)。
作为比较的示例，对于曲面(即，弯曲)液晶显示面板，例如曲率半径为15cm，假设D1～D5区域输入的灰阶电压值相同并且对应于各个区域的背光源的亮度相同，例如，D1～D5区域输入的灰阶电压值均为4V，并且LED灯的电流为20mA，检测到显示面板D3区域的色坐标为(0.30，0.32)，D1区域和D5区域的色坐标相同为(0.29，0.30)，D2区域和D4区域的色坐标相同为(0.295，0.31)。
从色坐标的检测结果可以看出，在针对各个区域输入的灰阶电压值相同并且对应于各个区域的背光源的亮度相同的情况下，D1区域和D5区域的色坐标偏低，D1区域和D5区域严重偏蓝。这是由于液晶显示面板在L255状态下，针对D1～D5区域的观看视角不同，如图8所示，液晶所处的长短轴状态不同，使得中间区域D3的Δn偏大，D1和D5区域Δn偏小，因此D1和D5区域会出现显示画面发蓝的现象。
作为本公开的示例，对于曲面(即，弯曲)液晶显示面板，例如，曲率半径为15cm，调整针对不同区域的灰阶电压值和LED灯的电流(背光源的亮度)，例如，D3区域的灰阶电压值为4V，LED灯的电流为20mA；D2区域和D4区域的灰阶电压值为3.5V，LED灯的电流为25mA；以及D1区域和D5区域的灰阶电压值为3V，LED灯的电流为30mA，然后对 显示面板D1～D5区域的色坐标进行检测，可以得到D3区域的色坐标依然为(0.30，0.32)，D2区域和D4区域的色坐标相同为(0.30，0.317)，并且D1区域和D5区域的色坐标相同为(0.295，0.315)。
由此可见，在调整不同区域的灰阶电压值后，液晶显示面板在L255状态下，液晶的扭转状态被改变(如图9(a)所示)。在这种情况下，如图9(b)所示，针对D1-D5区域中不同的观看视角，液晶所处的长短轴状态(扭转状态)基本相同，因此可以避免看到的显示画面存在色偏。此外，对显示面板10的D1～D5区域所对应的背光源的部分的亮度进行调整，可以确保显示面板10的D1～D5区域的亮度均一。
在示例的实施例中，如图10所示，检测单元20可以包括位置检测子单元202和弯曲程度检测子单元201，位置检测子单元202可以被配置为检测从观看位置到每个区域的距离；弯曲程度检测子单元201可以被配置为检测显示面板10在各个区域的弯曲程度。
在显示面板为小尺寸曲面显示面板的情况下，检测单元20可以仅包括弯曲程度检测子单元201。在显示面板为平面显示面板的情况下，检测单元20可以仅包括位置检测子单元202。在显示面板为大尺寸曲面显示面板的情况下，检测单元20可以包括弯曲程度检测子单元201和位置检测子单元202。
本公开对于位置检测子单元202和弯曲程度检测子单元201的个数不进行限定，例如，可以是1个，也可以是2个或更多个，本领域技术人员可以根据实际需要适宜地选择。作为示例，在曲面显示面板的表面是圆弧面的情况下，由于圆弧面的各个区域的曲率都相等，因此可以仅设置一个弯曲程度检测子单元201，通过该弯曲程度检测子单元201可以对圆弧面上任意一个区域的曲率进行检测。根据检测到的曲率便可以计算出该区域的观看视角。进一步地，根据n个区域中其他区域到该区域的距离，可以计算出其他区域的观看视角。作为又一示例，在曲面显示面板的表面为非圆弧面的情况下，由于曲面显示面板的n个区域的曲率可能不相等，因此需要在显示面板10的n个区域分别设置弯曲程度检测子单元201，通过n个弯曲程度检测子单元201对n个区域的弯曲程度进行检测。根据检测到的各个区域的弯曲程度便可以计算出n个区域的观看视角。
此处，本公开对于位置检测子单元202和弯曲程度检测子单元201的设置位置不进行限定，例如，可以设置在显示面板10上，也可以设置在其它基板上。当设置在其它基板上时，其它基板可以具有与与显示面板10上的n个区域一一对应的n个区域。
此外，本公开对于位置检测子单元202的类型不进行限定。作为示例，位置检测子单元202可以是红外传感器。本公开对于弯曲程度检测子单元201的类型不进行限定。作为示例，弯曲程度检测子单元201可以是曲率传感器，例如，光纤曲率传感器。
在本公开的实施例中，检测单元20包括独立的两个子单元，即，位置检测子单元202和弯曲程度检测子单元201，因此当显示面板10为平面显示面板时，检测单元20无需设置弯曲程度检测子单元201；当显示面板10为小尺寸曲面显示面板时，检测单元20无需设置位置检测子单元202，因而可以降低显示装置的生产成本。
在示例的实施例中，检测单元可以包括m个弯曲程度检测子单元201，m为正整数，且m≥n。
通过示例的方式，当m等于n时，可以在显示面板10的每个区域设置一个弯曲程度检测子单元201，使得n个弯曲程度检测子单元201可以分别对显示面板20的n个区域的弯曲程度进行检测。当m大于n时，可以在显示面板的弯曲程度较大的区域设置至少两个弯曲程度检测子单元201。通常，显示面板10的两侧的区域的弯曲程度较大，为了对显示面板10两侧的区域的弯曲程度进行精确检测，可以在显示面板10的两侧的弯曲程度较大的区域内设置两个或两个以上弯曲程度检测子单元201，而弯曲程度较小的其它区域设置一个弯曲程度检测子单元201。
在该示例中，由于m个弯曲程度检测子单元201可以分别对显示面板10的n个区域的弯曲程度进行检测，因而可以精确得到每个区域的弯曲程度，以便于根据每个区域的弯曲程度对显示面板10的各个区域的灰阶电压值和/或显示面板10的背光源的对应于各个区域的亮度的部分进行调整。
进一步示例的，弯曲程度检测子单元201可以设置在显示面板10上。替代地，显示装置还可以包括设置在与显示面板10的出光侧相背的一侧的柔性基板，弯曲程度检测子单元201可以设置在柔性基板40上(如图 11所示)。
在弯曲程度检测子单元201设置在柔性基板40上的实施例中，显示面板10可以与柔性基板40同步弯曲，即，显示面板10每个区域的弯曲程度与柔性基板40对应区域的弯曲程度相同，因此弯曲程度检测子单元201检测柔性基板40的弯曲程度相当于检测显示面板10的弯曲程度。
在示例的实施例中，如图12(a)所示，检测单元可以包括n个位置检测子单元202(附图12(a)中以n等于5为例进行示意)，该n个位置检测子单元202可以分别检测观看位置到显示面板10的n个区域的距离。
替代地，如图12(b)所示，检测单元可以包括1个位置检测子单元202，该1个位置检测子单元202用于检测观看位置到该一个位置检测子单元202所在区域的距离d，并根据观看位置和位置检测子单元202的连线与显示面板10的夹角β以及n个区域中其它区域到该1个位置检测子单元202所在的区域的距离，计算出观看位置到其它区域的距离。
在本公开的实施例中，通过设置位置检测子单元202，便可以对观看位置到显示面板10的各个区域的距离进行检测，然后根据观看位置到显示面板10的各个区域的距离，便可以计算出观看位置相对于显示面板10的各个区域的观看视角。
在另一方面，本公开的实施例还提供一种用于控制显示装置的方法。该方法可以适用于根据本公开的显示装置，诸如根据上面和/或下面更详细公开的一个或多个实施例的显示装置。因此，对于该方法的可选实施例，可以参考显示装置的实施例。该方法包括以下步骤，其可以以给定的顺序或以不同的顺序执行。此外，可以提供未列出的附加方法步骤。此外，可以至少部分地同时执行两个或更多个或甚至所有的方法步骤。此外，方法步骤可以重复执行两次或甚至多于两次。
在该方法的示例的实施例中，显示装置可以包括显示面板10，显示面板10沿观看水平方向被划分为n个区域，其中，n为正整数，且n≥2。如图13所示，所述方法包括步骤S100-S102。
在步骤S100，检测对应于n个区域中的每一个区域的观看视角。
在该实施例中，观看视角为人眼视线与显示面板之间的夹角。对应于每个区域的观看视角可以通过以下参数中的一种或两种来表征：i)观 看位置到显示面板的n个区域中的每个区域的距离；以及ii)显示面板在n个区域中的每个区域的弯曲程度。
在显示面板10为平面显示面板的情况下，平面显示面板的曲率为零，观看视角仅与观看位置到显示面板10的各个区域的距离有关，因而可以仅通过观看位置到显示面板10的各个区域的距离来表征观看视角。在显示面板10为小尺寸曲面显示面板的情况下，例如，可穿戴眼镜或可穿戴头盔，可近似认为显示面板的各个区域到观看位置的光线都是平行的，即，观看位置到显示面板10的各个区域的距离不影响观看视角。在这种情况下，观看视角仅与显示面板10在各个区域的弯曲程度有关，因此可以仅通过显示面板10在各个区域的弯曲程度来表征观看视角。在显示面板10为大尺寸曲面显示面板的情况下，观看视角与观看位置到显示面板10的各个区域的距离和显示面板10在各个区域的弯曲程度均有关，因此可以通过观看位置到显示面板10的各个区域的距离和显示面板10在各个区域的弯曲程度来表征观看视角。
此处，弯曲程度例如可以是通过曲率或曲率半径来表示。然而，这并不旨在将本公开的范围限制在弯曲程度的特定表示方式，本领域技术人员可以容易地认识到，当采用其他表示形式时如何适配相关的条件和设置。此外，本公开对于如何检测显示面板10在各个区域的弯曲程度不进行限定。作为示例，各个区域的弯曲程度可以通过曲率传感器进行检测。
类似地，本公开对于如何检测观看位置到显示面板10的各个区域的距离不进行限定。作为示例，该距离可以通过红外探测头进行检测。
在步骤S101，根据观看视角调整以下中的一种或多种：i)对显示面板10的所述观看视角所对应的区域的灰阶电压值；和ii)显示面板10的背光源对应于观看视角所对应的部分的亮度。
在该步骤中，在显示装置为液晶显示装置的情况下，液晶显示装置可以例如包括液晶显示面板和背光源，背光源用于为液晶显示面板提供光源。根据观看视角可以对显示面板10的观看视角所对应的区域的灰阶电压值进行调整。在替代的实施例中，也可以根据观看视角对显示面板10的背光源对应于观看视角所对应的区域部分的亮度进行调整。在另一替代的实施例中，也可以根据观看视角对显示面板10的观看视角所对应 的区域的灰阶电压值和显示面板10的背光源对应于观看视角所对应的亮度均进行调整。
在显示装置为有机电致发光二极管显示装置的情况下，可以根据观看视角对显示面板10的观看视角所对应的区域的灰阶电压值进行调整。
通过示例的方式，相应区域的灰阶电压值可以通过调整施加在数据线上的电压大小来实现。背光源的对应于相应区域的部分的亮度可以通过调整电流的大小来实现。
在本公开的实施例中，通过调整各个区域的灰阶电压值或者各个区域对应的背光源的部分的亮度，可以调整显示面板显示图像的均匀性，因此可以提高显示效果。
在本公开的示例的实施例中，如上所述，可以根据对应于显示面板的各个区域的观看视角对显示面板10的各个区域的灰阶电压值和显示面板10的背光源的对应于观看视角所对应的区域的部分的亮度中的一种或两种进行调整，因而可以对显示面板10显示的图像进行调整。作为示例，随着观看视角减小，可以通过如下一种或两种方式进行调整操作：i)减小显示面板10的观看视角所对应的区域的灰阶电压值，和ii)增大显示面板10的背光源对应于观看视角所对应的区域的部分的亮度。通过对施加在显示面板10的灰阶电压值和背光源的亮度中的一种或两种的调整，可以避免在侧视时或显示面板10弯曲时，观看者看到的显示画面的画质不均匀(例如，色偏)，从而改善显示画面的品质。
在显示面板10为液晶显示面板的情况下，随着观看视角的减小，作为一个示例，可以减小显示面板10的观看视角所对应的区域的灰阶电压值；作为另一示例，可以增大显示面板10的背光源对应于观看视角所对应的区域的部分的亮度；作为又一示例，可以减小显示面板10的观看视角所对应的区域的灰阶电压值，并且增大显示面板10的背光源对应于观看视角所对应的区域的部分的亮度。在显示面板10为有机电致发光二极管显示面板的情况下，随着观看视角减小，可以仅减小显示面板10的观看视角所对应的区域的灰阶电压值。
此处，对于相应区域的灰阶电压值的减小幅度和背光源的增大幅度可以根据观看视角的大小来确定，以使得通过调整由显示面板10显示的图像没有或具有较小的色偏。通过示例的方式，观看视角越小，灰阶电 压值的减小的越多，并且背光源的亮度增大的越多。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
