具体实施方式
为了使本公开的目的、技术方案和优点更加清楚，下面结合附图，对本公开实施例提供的显示面板的驱动方法、显示驱动电路及显示装置的具体实施方式进行详细地说明。显然，所描述的实施例仅仅是本公开一部份实施例，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它实施例，都属于本公开保护的范围。
本公开实施例提供的一种显示面板的驱动方法，如图1所示，包括以下步骤：
S101、数据驱动芯片接收图形处理器发送的待显示图像；待显示图像中包含高清显示区域和低清显示区域的灰阶数据；
S102、数据驱动芯片根据高清显示区域的位置，控制连接的显示面板中包含高清显示区域的各行亚像素进行逐行扫描；
S103、数据驱动芯片根据低清显示区域的位置，控制显示面板中仅包含低清显示区域的各行亚像素进行N行同时扫描；其中，N为大于1的偶数。
具体地，在本公开实施例提供的上述显示面板的驱动方法中，在数据驱动芯片接收图形处理器发送的待显示图像后，由于数据驱动芯片根据待显示图像中的高清显示区域的位置，控制连接的显示面板中包含高清显示区域的各行亚像素进行逐行扫描，因此，可以满足高清显示区域的成像清晰显示。并且，由于数据驱动芯片同时根据待显示图像中的低清显示区域的位置，控制显示面板中仅包含低清显示区域的各行亚像素进行N行同时扫描，其中N 为大于1的偶数；相对于逐行扫描，可以加快低清显示区域的刷新速度，由此有效减小每帧显示的刷新行数，并有效减小每帧显示的整体扫描行数，可以节省每帧扫描时间；而在同等每帧扫描时间的情况下，可以增大显示面板的充电时间，以实现高速且低功耗显示需求。
具体地，在本公开实施例提供的上述显示面板的驱动方法中，步骤S102和步骤S103一般同时进行，不分先后顺序。且在步骤S103中对于N行同时扫描的选择可以有多种，例如两行同时扫描、四行同时扫描或八行同时扫描等，在此不做限定。下面以数据驱动芯片控制仅包含低清显示区域的各行亚像素进行四行同时扫描为例进行说明。
具体地，在本公开实施例提供的上述显示面板的驱动方法中，步骤S102和步骤S103中数据驱动芯片控制连接的显示面板中进行扫描行数的变化，主要是通过控制向显示面板加载的时钟信号的变化实现的。具体地，如图2和图5所示，在仅包含低清显示区域a1和a2的各行亚像素进行扫描时，数据驱动芯片可以对显示面板的时钟信号端CLK1-4同时加载相同的第一时钟信号，同时对显示面板的时钟信号端CLK5-8加载与第一时钟信号相反的第二时钟信号，以实现仅包含低清显示区域a1和a2的各行亚像素以每4行同时扫描。在包含高清显示区域b的各行亚像素进行扫描时，如图2中虚线框所示，数据驱动芯片可以对显示面板的时钟信号端CLK1-4依次时加载第一时钟信号，同时对显示面板的时钟信号端CLK5-8分别加载与时钟信号端CLK1-4的第一时钟信号相反的第二时钟信号，以实现包含高清显示区域的各行亚像素逐行进行扫描。
可选地，在本公开实施例提供的上述驱动方法中，显示面板中亚像素的排列方式可以有多种，例如图3所示，亚像素可以在行方向和列方向均对齐排列，且每列亚像素的显示颜色均相同。又如图4所示，显示面板中每相邻的两行亚像素中各亚像素之间在列方向错开X个子像素的位置，0<X<1，每个亚像素与相邻的各亚像素的显示颜色各不相同，此时，数据线也从图3所示的直线延伸，变更为图4所示的折线延伸，且为了保证一条数据线与仅与 相同显示颜色的亚像素连接，数据线会分别和两侧的亚像素通过开关晶体管连接。
具体实施时，图4所示的像素排布在显示时采用特定的驱动方法能够实现高于物理分辨率一倍的显示分辨率。因此，图4所示的像素排布可以在与图3所示的传统像素排布同等显示分辨率的情况下，节省一半的亚像素数量和一半的数据线数量，由此有效降低显示面板的工艺难度。
可选地，在本公开实施例提供的上述驱动方法中，在执行步骤S103数据驱动芯片控制显示面板中仅包含低清显示区域的各行亚像素进行N行同时扫描的同时，还可以执行以下步骤：
数据驱动芯片对仅包含低清显示区域的每N行亚像素中，与同一数据线连接的显示颜色相同的各亚像素输入相同的灰阶数据；即，在N行亚像素同时进行扫描时，一条数据线会同时与这N行亚像素中的N个显示颜色相同的亚像素导通，对这N个亚像素加载相同的灰阶数据，例如，一条与红色亚像素连接的数据线会在四行亚像素同时扫描时，对四个红色亚像素加载相同的灰阶数据。
具体地，在数据驱动芯片控制显示面板中仅包含低清显示区域的各行亚像素进行N行同时扫描，加快低清显示区域的刷新速度，由此有效减小每帧显示的刷新行数，并有效减小每帧显示的整体扫描行数，节省每帧扫描时间，增大显示面板的充电时间的基础上，数据驱动芯片对仅包含低清显示区域的每N行亚像素中，与同一数据线连接的显示颜色相同的各亚像素输入相同的灰阶数据，可以降低数据驱动芯片对数据线加载的灰阶数据量，由此减少数据驱动芯片内部数据处理量，以节省数据驱动芯片的功耗。
在图4所示的像素排布结构基础上，在本公开实施例提供的上述显示面板的驱动方法中，数据驱动芯片对仅包含低清显示区域的每N行亚像素中，与同一数据线连接的显示颜色相同的各亚像素输入相同的灰阶数据的同时，还可以执行以下步骤：
数据驱动芯片对仅包含低清显示区域的偶数行亚像素中的边缘亚像素， 根据邻近的显示颜色相同的亚像素灰阶和权重调整并输出相应的灰阶数据，即对偶数行的左侧边缘亚像素B需要单独进行边缘灰阶数据调整，可以按照其右侧和上下相邻的三个亚像素B的权重和灰阶数据，进行像素的灰阶数据赋值，以满足显示要求。
可选地，在本公开实施例提供的上述驱动方法中，如图5所示，由于高清显示区域b一般仅在显示面板的中间部分，不会覆盖整行亚像素，因此步骤S102数据驱动芯片根据高清显示区域的位置，控制连接的显示面板中包含高清显示区域的各行亚像素进行逐行扫描，一般包括：
数据驱动芯片根据高清显示区域的位置，控制同时包含高清显示区域和低清显示区域的各行亚像素进行逐行扫描，即数据驱动芯片控制在图5中的同时包含高清显示区域b和低清显示区域a3和a4的各行亚像素进行逐行扫描。
可选地，在本公开实施例提供的上述驱动方法中，数据驱动芯片根据高清显示区域的位置，控制同时包含高清显示区域和低清显示区域的各行亚像素进行逐行扫描的同时，还可以执行以下步骤：
数据驱动芯片对同时包含高清显示区域和低清显示区域的每N行亚像素中，在低清显示区域中与同一数据线连接的显示颜色相同的各亚像素输入相同的灰阶数据。如图5所示，虽然在高清显示区域b两侧的低清显示区域a3和a4也为逐行扫描，但是通过数据驱动芯片对低清显示区域a3和a4的线缓存(line buffer)中的一行像素内容读出四行，分别给低清显示区域a3和a4中的四行亚像进行显示，可以降低数据驱动芯片对数据线加载的灰阶数据量，由此减少数据驱动芯片内部数据处理量，以节省数据驱动芯片的功耗。具体地，对于低清显示区域a3和a4中奇数行的亚像素，数据驱动芯片可以直接发送灰阶数据进行显示，对于图4所示的像素排布中的偶数行需要对应做像素调整，将像素内的RGB与BRG的灰阶数据进行调换后发送进行显示。
可选地，在本公开实施例提供的上述驱动方法中，数据驱动芯片根据高清显示区域的位置，控制连接的显示面板中包含高清显示区域的各行亚像素进行逐行扫描，还包括：
数据驱动芯片对同时包含高清显示区域和低清显示区域的每N行亚像素中，低清显示区域的偶数行亚像素中的边缘亚像素，根据邻近的显示颜色相同的亚像素灰阶和权重调整并输出相应的灰阶数据。
可选地，在本公开实施例提供的上述驱动方法中，数据驱动芯片根据高清显示区域的位置，控制连接的显示面板中包含高清显示区域的各行亚像素进行逐行扫描，包括：
数据驱动芯片对显示面板中包含高清显示区域的各行亚像素中的高清区域的各个亚像素，根据待显示图像中高清区域的灰阶数据调整并输出相应的灰阶数据。
在具体实施时，对于高清区域的各个亚像素，根据待显示图像中高清区域的灰阶数据调整并输出相应的灰阶数据具体为：以图8为例，高清显示区域中的3列像素单元在原始图像中对应6列像素单元，根据原始图像中的6列像素单元的灰阶数据进行计算，通过算法可以换算得到高清显示区域中的3列像素单元分别对应的灰阶数据，然后根据换算的灰阶数据对显示面板的实际像素排布进行灰阶数据赋值，从而通过3列像素单元实现6列像素单元的显示效果，即实现高于物理分辨率一倍的显示分辨率。
具体地，根据原始图像中的灰阶数据计算高清显示区域各像素单元分别对应的灰阶数据可以采用如下算法获得：
Stp1、将原始图像划分为理论像素单元，每个理论像素单元包括多个颜色不同的理论亚像素，计算每个理论亚像素的理论亮度值；
Stp2、计算每个实际亚像素的实际亮度值，包括：
Stp21、找出第一理论亚像素，该第一理论亚像素在原始图像中的位置与待计算的实际亚像素在显示面板的像素阵列中的位置相对应；
Stp22、在第一理论亚像素与至少一个相邻理论亚像素之间插入多个与该第一理论亚像素同色的虚拟亚像素，相邻理论亚像素为第一理论亚像素所在的行中，与该第一理论亚像素颜色相同的所有理论亚像素中与该第一理论亚像素邻近的理论亚像素；
Stp23、将第一理论亚像素的理论亮度值的一部分与位置与待计算的实际亚像素相对应的虚拟亚像素的虚拟亮度值的一分部相加所得的值即为待计算的实际亚像素的实际亮度值，其中，虚拟亚像素的虚拟亮度值为该第一理论亚像素的理论亮度值的一部分以及相应的相邻理论亚像素的一部分之和；
Stp3、向各个实际亚像素输入信号，以使各实际亚像素达到步骤stp2中所计算得到的实际亮度值。可选地，在本公开实施例提供的上述驱动方法中，如图6所示，在数据驱动芯片接收图形处理器发送的待显示图像之前，还可以包括以下步骤：
S601、图形处理器按设定的压缩比例压缩原始图像中的低清显示区域的灰阶数据；
S602、图形处理器将压缩后的低清显示区域的灰阶数据与高清显示区域的灰阶数据融合后发送至数据驱动芯片；
S603、数据驱动芯片根据显示面板中数据线的数量和压缩比例，拉伸接收到的低清显示区域的灰阶数据。
具体地，通过上述在图形处理器中执行的步骤S601和S602可以保证高清显示区域显示数据的同时，可以使从图形处理器到数据驱动芯片的传输数据量较小，以提高数据传输速度，从而可以支持更高图像输出帧频，降低GPU的输出延迟，提升了用户体验。
可选地，在本公开实施例提供的上述驱动方法中，上述步骤S601中压缩比例中纵向压缩N倍，横向可以是压缩M倍；例如图7所示，图形处理器接收到的原始图像的分辨率为4320*4800，确定其中高清显示区域b的分辨率为1440*1600，将低清显示区域a的分辨率按照纵向四倍压缩且横向三倍压缩的压缩比例进行压缩，压缩后的低清显示区域a的分辨率为1440*1200。执行上述步骤S602之后，低清显示区域a的灰阶数据与高清显示区域b的灰阶数据融合后分辨率为1440*2800。
对应地，上述步骤S603数据驱动芯片根据显示面板中数据线的数量和压缩比例，拉伸接收到的低清显示区域的灰阶数据，包括：数据驱动芯片根据 显示面板中数据线的数量和压缩比例中的横向压缩比例，仅横向拉伸接收到的低清显示区域的灰阶数据，横向拉伸的比例与数据线的数量及压缩比例中的横向压缩比例成正比。其中，横向拉伸的比例/横向压缩比例＝原始图像像素列数/数据线条数。
以图3所示的像素排布为例，数据线的数量和原始图像的列数一致，数据驱动芯片需要进行M倍的横向拉伸，即需要横向3倍拉伸，即根据一行中的一个亚像素生成三个亚像素的灰阶数据。
以图4所示的像素排布为例，数据线的数量比原始图像的列数减少一半，数据驱动芯片需要进行M/2倍的横向拉伸，即需要横向1.5倍拉伸，即根据一行中的两个亚像素生成三个亚像素的灰阶数据。图9示出了低清显示区域中的四个像素单元经过1.5倍横向拉伸变为六个像素单元的灰阶数据，之后根据显示面板的实际像素排布向六个像素单元进行灰阶数据赋值，使N＝4行亚像素使用相同一行灰阶数据进行驱动显示的过程。图8示出了原始图像中高清显示区域中的六列像素单元的灰阶数据，根据显示面板的实际像素排布对显示面板中的三列像素单元进行灰阶数据赋值的情况。图11从左至右依次示出了原始图像中高清显示区域中的六列像素单元的灰阶数据，经图形处理器处理后的高清显示区域中的六列像素单元的灰阶数据(该六列像素单元的灰阶数据与原始图像中对应的六列像素单元的灰阶数据一致)，以及根据图形处理器处理后的高清显示区域中的六列像素单元的灰阶数据对显示面板的高清显示区域中对应的三列像素单元进行灰阶数据赋值的情况。
基于同一发明构思，本公开实施例还提供了一种上述显示驱动电路，由于该显示驱动电路解决问题的原理与前述一种驱动方法相似，因此该电路的实施可以参见驱动方法的实施，重复之处不再赘述。
