具体实施方式
为了达到高对比度与低功耗的显示效果，显示屏会依照每一帧显示画面动态调整输出亮度，即调整每一帧画面对应的峰值亮度参数PBP(Peak Brightness Parameter)。其中，PBP＝P_real/P_max，P_max为显示屏显示最大功耗画面时所需的功耗，P_real为显示屏显示当前帧画面时所需的功耗。
在拼接显示屏中，由于各显示面板用于调整输出亮度的峰值亮度参数是根据显示画面得到的，因此，当不同显示面板显示的画面内容不同时，容易在拼接区域造成亮度差异，从而影响拼接显示屏的整体画面质量。
有鉴于此，本公开实施例提供了一种显示装置及其显示方法，用以改善 拼接处的亮度差异。

需要说明的是，在以下描述中阐述了具体细节以便于充分理解本公开。但是本公开能够以多种不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本公开内涵的情况下做类似推广。因此本公开不受下面公开的具体实施方式的限制。说明书后续描述为实施本公开的较佳实施方式，然所述描述乃以说明本公开的一般原则为目的，并非用以限定本公开的范围。本公开的保护范围当视所附权利要求所界定者为准。
下面结合附图，对本公开实施例提供的显示装置及其显示方法进行具体说明。
本公开实施例提供的一种显示装置的显示方法，其中，显示装置包括：N个显示面板，N为大于1的整数；如图1所示，显示方法包括：
S101、接收待显示帧图像数据；
S102、将待显示帧图像数据分割为与N个显示面板一一对应的N帧子图像数据；
S103、针对每一显示面板，根据其对应的子图像数据计算该显示面板对应的初始峰值亮度参数；
S104、针对每一显示面板，根据其自身对应的初始峰值亮度参数以及与其相邻的显示面板对应的初始峰值亮度参数计算其对应的目标峰值亮度参数；
S105、显示面板根据其对应的子图像数据以及目标峰值亮度参数进行显 示。
本公开实施例提供的上述显示方法，接收待显示帧图像数据，然后将待显示帧图像数据分割为与N个显示面板一一对应的N帧子图像数据；针对每一显示面板，根据其对应的子图像数据计算该显示面板对应的初始峰值亮度参数，根据其自身对应的初始峰值亮度参数以及与其相邻的显示面板对应的初始峰值亮度参数计算其对应的目标峰值亮度参数；显示面板根据其对应的子图像数据以及目标峰值亮度参数进行显示。由于每一显示面板对应的目标峰值亮度参数是由根据其自身对应的初始峰值亮度参数以及与其相邻的显示面板对应的初始峰值亮度参数得到的，即每一显示面板的输出亮度既考虑了自身的画面内容，也考虑了与其相邻显示面板的画面内容，从而降低相邻显示面板的输出亮度差异，改善相邻显示面板在拼接处的亮度差异，提高显示装置的整体显示效果。
可选地，在本公开实施例提供的上述显示方法中，如图2所示，每一显示面板的显示区域被划分为中心区域A1和包围中心区域A1的周边区域A21和A22。
步骤S104针对每一显示面板，根据其自身对应的初始峰值亮度参数以及与其相邻的显示面板对应的初始峰值亮度参数计算其对应的目标峰值亮度参数，包括：
针对每一显示面板，将其自身对应的初始峰值亮度参数确定为中心区域对应的目标峰值亮度参数；
根据其自身对应的初始峰值亮度参数以及与其相邻的显示面板对应的初始峰值亮度参数计算周边区域对应的目标峰值亮度参数。
步骤S105显示面板根据其对应的子图像数据以及目标峰值亮度参数进行显示，具体为：
显示面板根据中心区域和周边区域分别对应的目标峰值亮度参数以及子图像数据进行显示。
在上述实施例中，将显示面板自身对应的初始峰值亮度参数作为中心区 域对应的目标峰值亮度参数，从可以保证显示面板自身的显示品质。根据显示面板自身对应的初始峰值亮度参数以及与其相邻的显示面板对应的初始峰值亮度参数计算周边区域对应的目标峰值亮度参数，在保证显示面板周边区域显示品质的基础上降低相邻显示面板在拼接处的亮度差异。
可选地，在本公开实施例提供的上述显示方法中，如图2所示，显示面板的显示区域被划分为呈3行×3列的9个显示子区域a1～a9；其中：
位于第2行第2列的显示子区域a5为中心区域A1；
周边区域包括4个第一周边子区域A21和4个第二周边子区域A22；位于第x行第y列的显示子区域(a1、a3、a7和a9)为第一周边子区域A21，其中，x＝1或3，y＝1或3；位于第n行第m列的显示子区域(a2、a4、a6和a8)为第二周边子区域A22，其中，n＝2，m＝1或3，或者，m＝2，n＝1或3。
在具体实施时，根据其自身对应的初始峰值亮度参数以及与其相邻的显示面板对应的初始峰值亮度参数计算周边区域对应的目标峰值亮度参数，包括：
针对每一显示面板中的各第一周边子区域，根据显示面板自身对应的初始峰值亮度参数、与第一周边子区域沿行方向相邻的显示面板对应的初始峰值亮度参数、与第一周边子区域沿列方向相邻的显示面板对应的初始峰值亮度参数、与第一周边子区域沿对角线方向相邻的显示面板对应的初始峰值亮度参数计算第一周边子区域对应的目标峰值亮度参数；
针对每一显示面板中的各第二周边子区域，根据显示面板自身对应的初始峰值亮度参数、与第二周边子区域沿行方向相邻或者沿列方向相邻的显示面板对应的初始峰值亮度参数计算第二周边子区域对应的目标峰值亮度参数。
例如，以图3中的显示面板1为例，针对显示面板1中的各第一周边子区域，显示子区域a1没有相邻的显示面板，显示子区域a1对应的目标峰值亮度参数只能根据显示面板1对应的初始峰值亮度参数来计算。显示子区域a7，只有显示面板4与其沿列方向相邻，因此显示子区域a7对应的目标峰值亮度参数只能根据显示面板1对应的初始峰值亮度参数和显示面板4对应的初始 峰值亮度参数来计算。显示子区域a3，只有显示面板2与其沿行方向相邻，因此显示子区域a3对应的目标峰值亮度参数只能根据显示面板1对应的初始峰值亮度参数和显示面板2对应的初始峰值亮度参数来计算。显示子区域a9，显示面板4与其沿列方向相邻，显示面板2与其沿行方向相邻，显示面板5与其沿对角线方向相邻，因此显示子区域a9对应的目标峰值亮度参数需要根据显示面板1对应的初始峰值亮度参数、显示面板2对应的初始峰值亮度参数、显示面板4对应的初始峰值亮度参数以及显示面板5对应的初始峰值亮度参数来计算。对于其它显示面板中各第一周边子区域对应的目标峰值亮度参数的计算原理与显示面板1相似，在此不作赘述。
仍以图3中的显示面板1为例，针对显示面板1中的各第二周边子区域，显示子区域a2和a4没有相邻的显示面板，显示子区域a2和a4对应的目标峰值亮度参数只能根据显示面板1对应的初始峰值亮度参数来计算。显示子区域a8，只有显示面板4与其沿列方向相邻，因此显示子区域a8对应的目标峰值亮度参数只能根据显示面板1对应的初始峰值亮度参数和显示面板4对应的初始峰值亮度参数来计算。显示子区域a6，只有显示面板2与其沿行方向相邻，因此显示子区域a6对应的目标峰值亮度参数只能根据显示面板1对应的初始峰值亮度参数和显示面板2对应的初始峰值亮度参数来计算。对于其它显示面板中各第二周边子区域对应的目标峰值亮度参数的计算原理与显示面板1相似，在此不作赘述。
可选地，在本公开实施例提供的上述显示方法中，根据如下公式计算显示面板中各第一周边子区域对应的目标峰值亮度参数PBP：
PBP＝k 1PBP 1+k 2PBP 2+k 3PBP 3+k 4PBP 4；
其中，PBP 1表示显示面板对应的初始峰值亮度参数，PBP 2表示与第一周边子区域沿行方向相邻的显示面板对应的初始峰值亮度参数，PBP 3表示与第一周边子区域沿列方向相邻的显示面板对应的初始峰值亮度参数；PBP 4表示与第一周边子区域沿对角线方向相邻的显示面板对应的初始峰值亮度参数；k 1～k 4表示权重系数，且k 1≥k 2＝k 3≥k 4。
需要说明的是，在本公开中，对于第一周边子区域，当该第一周边子区域沿行方向没有相邻的显示面板时，PBP 2＝0，k 2＝0；当该第一周边子区域沿列方向没有相邻的显示面板时，PBP 3＝0，k 3＝0；当该第一周边子区域沿对角线方向没有相邻的显示面板时，PBP 4＝0，k 4＝0。
可选地，在一些实施例中，对于每一第一周边子区域，其自身显示面板以及各与其相邻显示面板对应的权重系数相同，使相邻显示面板的相邻第一周边子区域的目标峰值亮度参数相同，即在拼接处，相邻显示面板的目标峰值亮度参数相同。例如图3中的显示面板1的显示子区域a9、显示面板2的显示子区域a7、显示面板4的显示子区域a3和显示面板5的显示子区域a1，由于k 1＝k 2＝k 3＝k 4＝1/4，因此其对应的目标峰值亮度参数均相同。例如图3中的显示面板1的显示子区域a3和显示面板2的显示子区域a1，由于k 3＝0，k 4＝0，k 1＝k 2＝1/2，因此其对应的目标峰值亮度参数均相同。例如图3中的显示面板1的显示子区域a7和显示面板4的显示子区域a1，由于k 2＝0，k 4＝0，k 1＝k 3＝1/2，因此其对应的目标峰值亮度参数均相同，从而改善拼接处相邻显示面板的亮度差异。
可选地，在一些实施例中，如图2所示，第一周边子区域A21沿远离显示面板中心的方向被依次划分多个亚子区域A211～A213(图2以3个亚子区域为例)；
各亚子区域对应的目标峰值亮度参数PBP＝k 1PBP 1+k 2PBP 2+k 3PBP 3+k 4PBP 4，离显示面板中心越远的亚子区域，k 1越小，k 2、k 3和k 4越大。例如图2中，由亚子区域A211至亚子区域A213，k 1越来越小，k 2、k 3和k 4越来越大。
在上述实施例中，使第一周边子区域对应的目标峰值亮度参数由与中心区域对应目标峰值亮度参数接近逐渐过渡到与相邻的显示面板的第一周边子区域对应的目标峰值亮度参数接近，可以进一步的提高显示品质。
可选地，在一些实施例中，第一周边子区域中，离显示面板中心最远的亚子区域，其自身显示面板以及各与其相邻显示面板对应的权重系数相同。 例如图2中，对于亚子区域A213，如果仅在行方向有相邻的显示面板，则k 1＝k 2＝1/2，如果仅在列方向有相邻的显示面板，则k 1＝k 3＝1/2，如果在行方向、列方向和对角线方向均有相邻的显示面板，则k 1＝k 2＝k 3＝k 4＝1/4。从而在拼接处，相邻显示面板的目标峰值亮度参数相同，从而改善拼接处相邻显示面板的亮度差异。
可选地，在一些实施例中，显示面板用于根据如下公式计算第二周边子区域对应的目标峰值亮度参数PBP：
PBP＝k 1PBP 1+k 2PBP 2；
其中，PBP 1表示显示面板对应的初始峰值亮度参数，PBP 2表示与第二周边子区域沿行方向相邻或者沿列方向相邻的显示面板对应的初始峰值亮度参数；k 1～k 2表示权重系数，且k 1≥k 2，k 1+k 2＝1。
需要说明的是，在本公开中，对于第二周边子区域，当该第二周边子区域沿行方向和列方向均没有相邻的显示面板时，PBP 2＝0，k 2＝0。
可选地，在一些实施例中，对于第二周边子区域，当该第二周边子区域存在相邻的显示面板时，k 1＝k 2＝1/2，使相邻显示面板的相邻第二周边子区域的目标峰值亮度参数相同，即在拼接处，相邻显示面板的目标峰值亮度参数相同，如图3中的显示面板1的显示子区域a6和显示面板2的显示子区域a4的目标峰值亮度参数相同，从而改善拼接处相邻显示面板的亮度差异。
可选地，在一些实施例中，如图2所示，第二周边子区域A22沿远离显示面板中心的方向被依次划分多个亚子区域A221～A223(图2以3个亚子区域为例)；
各亚子区域对应的目标峰值亮度参数PBP＝k 1PBP 1+k 2PBP 2，离显示面板中心越远的亚子区域，k 1越小，k 2越大。例如图2中，由亚子区域A221至亚子区域A223，k 1越来越小，k 2越来越大。
在上述实施例中，使第二周边子区域对应的目标峰值亮度参数由与中心区域对应目标峰值亮度参数接近逐渐过渡到与相邻的显示面板的第二周边子区域对应的目标峰值亮度参数接近，可以进一步的提高显示品质。
可选地，在一些实施例中，第二周边子区域中，离显示面板中心最远的亚子区域，其自身显示面板以及与其相邻显示面板对应的权重系数相同。例如图2中，对于亚子区域A223，如果存在与其相邻的显示面板时，k 1＝k 2＝1/2。即在拼接处，相邻显示面板的目标峰值亮度参数相同，从而改善拼接处相邻显示面板的亮度差异。
具体地，显示面板中，周边区域的范围可以根据显示面板的尺寸等实际亮度差异情况来确定，在此不作限定。可选地，在一些实施例中，第二周边子区域A22的面积大于或等于第一周边子区域A21的面积的2倍时，显示效果较佳。
