具体实施方式
下面将结合本申请实施例中的附图，对本申请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申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明，若本申请实施例中有涉及方向性指示(诸如上、下、左、右、前、后……)，则该方向性指示仅用于解释在某一特定姿态(如附图所示)下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
另外，若本申请实施例中有涉及“第一”、“第二”等的描述，则该“第一”、“第二”等的描述仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。另外，全文中出现的“和/或”的含义为，包括三个并列的方案，以“A和/或B”为例，包括A方案，或B方案，或A和B同时满足的方案。另外，各个实施例之间的技术方案可以相互结合，但是必须是以 本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本申请要求的保护范围之内。
图1所示是一范例的显示面板的结构示意图，显示面板包括多个像素110’，多条数据线200’和多条扫描线300’。其中，像素110’包括子像素111’。通常，一个像素110’包括三种子像素111’，分别为红子像素、绿子像素和蓝子像素，从而通过空间混色原理实现彩色图像的显示。子像素111’呈矩形阵列状排布，数据线200’与子像素列相间排布，且位于同一列上的子像素与同一数据线200’电连接，扫描线300’与子像素行相间排布，且位于同一行上的子像素与同一扫描线300’电连接。在扫描线300’上的扫描信号Gm’作用下，各行子像素111’分别打开，当子像素111’打开时，在数据线200’上的驱动信号Dn’的驱动作用下，子像素111’被充电，从而显示出一定的亮度。如图2所示为一种具体的显示面板的驱动方式，其中，图2(a)和图2(b)分别表示相邻两帧显示面板中驱动信号Dn’施加到子像素111’上的驱动极性，显示面板被点反转或类似点反转的方式驱动。那么，在一帧的时间内，数据线200’上的驱动信号Dn’的极性将按照+---+++---…或-+++---+++…的规律变化，在一帧的时间内，数据线上的驱动信号将经历多次极性反转，驱动信号Dn’的频率很高。
本申请提出一种显示面板，在本申请的一实施例中，如图3和图4所示，显示面板包括多个像素组100和多条数据线200，像素组100包括主像素110和次像素120，主像素110包括主子像素111，次像素120包括次子像素121，主子像素111和次子像素121呈矩形阵列状排布，且位于同一列上的主子像素111和次子像素121形成一子像素列；数据线200沿纵向延伸，且数据线200沿横向排布，数据线200与子像素列沿横向相间排布；其中，主像素110的驱动亮度大于主像素110的原始亮度，次像素120的驱动亮度小于次像素120的原始亮度；一数据线200与相邻两子像素列中驱动极性相同的主子像素111和次子像素121电连接，且一主子像素111仅与一数据线200电连接，一次子像素121仅与一数据线200电连接。
后文中将以液晶显示面板为例，对本申请的技术方案详细阐述。其中， 主子像素或次子像素包括子像素电极和开关器件，开关器件包括源电极、漏电极和栅电极，源电极与主子像素或次子像素对应的数据线电连接，漏电极与子像素电极电连接。其中，子像素电极由透明导电材料，如铟锡氧化物(ITO)制成。数据线通过开关器件对子像素电极充电，进而控制液晶偏转以显示一定的亮度。当然，显示面板还可以包括公共线和多个存储电容，存储电容与子像素一一对应设置，以维持液晶的偏转方向至下一帧图像。
在显示面板中，每一像素组100可以包括多个主像素110和次像素120，在本实施例中，为了简便起见，以一个像素组100包括一个主像素110和一个次像素120为例进行说明。由于受到液晶偏转的限制，如图4所示，在一范例中，偏视角情况下显示面板的穿透率-驱动电压曲线相对正视角情况下的穿透率-驱动电压曲线将发生漂移，导致画面的对比度降低，产生色偏和可视角变小的现象。如图5和图6中虚线所示，在理想情况下，偏视角下的归一化亮度和正视角下的归一化亮度呈线性关系，然而，如图6中实线所示，在实际情况下，偏视角下的归一化亮度和正视角下的归一化亮度呈非线性关系，导致显示面板的可视角变小，且产生色偏。如图7所示，在另一范例中，为了纠正显示面板的可视角变小和色偏的现象，将像素或子像素拆分为A和B两部分，并控制A部分和B部分分别显示不同的亮度。在图7中，两条点划线分别对应A部分和B部分的归一化亮度在偏视角和正视角下的关系，其中，A部分实际显示的亮度偏高，B部分实际显示的亮度偏低，而A部分和B部分最终混合的效果如图7中实线所示，接近于图7中虚线所示的理想情况，从而提高了显示面板的可视角，减小了色偏。然而，这种对像素或子像素本身进行分区的方式，将导致显示面板中像素或子像素的穿透率下降，使显示面板的显示质量变差。而在本实施例中，如图3和图4所示，通过将像素组100中的像素分为主像素110和次像素120，并控制主像素110的驱动亮度大于其原始亮度，次像素120的驱动亮度小于其原始亮度，以模拟如图7中所示的A部分和B部分的归一化亮度在偏视角和正视角下的关系。其中，原始亮度是指根据最初的显示画面直接确定的显示亮度，而驱动亮度是相对原始亮度增大或减小后的亮度，从而在保障主像素110和次像素120的穿透率不变的前提下，增大显示面板的可视角，减小色偏，改善显示面板的显示效果。
其中，主像素110和次像素120本身可以采用相同或相似的结构，即主像 素110包括主子像素111，次像素120包括次子像素121。通常，主像素110包括三种主子像素，分别为红主子像素、绿主子像素和蓝主子像素，并按照一定的规律排布；同理，次像素120包括三种次子像素，分别为红次子像素、绿次子像素和蓝次子像素，并按照一定的规律排布，以实现彩色画面的显示。从显示面板的整体看来，其中的主子像素111和次子像素121呈矩形阵列状排布，且位于同一列上的主子像素111和次子像素121形成一子像素列，与沿纵向延伸的数据线200相间排布，以便实现数据线200和主子像素111与次子像素121之间的电连接，减少跨线情况的发生。为了降低数据线200上的驱动信号Dn的极性反转频率，即降低驱动信号Dn的频率，数据线200与相邻两子像素列中驱动极性相同的主子像素111和次子像素121电连接，同时，一个主子像素111仅与一条数据线200电连接，且一个次子像素121仅与一条数据线200电连接，以免多条数据线控制同一子像素造成驱动的混乱。当采用上述方式连接主子像素111、次子像素121和数据线200时，若采用图2所述的驱动方式驱动显示面板，则在一帧的时间内，数据线200上的驱动信号Dn的极性将按照++++++++++…或----------…的规律变化。也就是说，在一帧对应的时长内，数据线200上的驱动信号的极性不变，从而降低了驱动信号的频率，减少了电路中产生的热量，进而降低了显示面板的显示功耗，同时避免了因电路过热产生的安全隐患。当然，在帧转换时，数据线200上驱动信号Dn的极性可以发生反转，以避免显示面板的极化和公共电压的偏移。
在本实施例中，显示面板包括多个像素组100和多条数据线200，像素组100包括主像素110和次像素120，主像素110包括主子像素111，次像素120包括次子像素121，主子像素111和次子像素121呈矩形阵列状排布，且位于同一列上的主子像素111和次子像素121形成一子像素列；数据线200沿纵向延伸，且数据线200沿横向排布，数据线200与子像素列沿横向相间排布；其中，主像素110的驱动亮度大于主像素110的原始亮度，次像素120的驱动亮度小于次像素120的原始亮度；一数据线200与相邻两子像素列中驱动极性相同的主子像素111和次子像素121电连接，且一主子像素111仅与一数据线200电连接，一次子像素121仅与一数据线200电连接。在显示面板的工作过程中，数据线200上的驱动信号对主子像素111和次子像素121充电， 以控制主子像素111和次子像素121的亮度。其中，主像素110的驱动亮度大于主像素110的原始亮度，次像素120的驱动亮度小于次像素120的原始亮度，以改善显示面板大视角下的色偏状况，增大显示面板的可视角。同时，当相邻两子像素列中驱动极性相同的主子像素111和次子像素121均连接到同一数据线上时，至少在显示画面一帧对应的时长内，数据线200上驱动信号的极性可以保持不变，相比将不同驱动极性的主子像素111和次子像素121连接到同一数据线200上的情形，所需的驱动信号的频率大幅降低，从而有效降低了显示面板的驱动功耗，同时减少了高频的驱动信号所产生的热量，避免了电路过热导致的安全隐患。
在显示面板中，数据线上的驱动信号Dn的驱动极性周期性反转，反转周期可以是显示面板的帧频对应的周期的整数倍，以实现帧与帧之间的反转，从而避免显示面板中产生极化，减小公共电压的偏移，改善显示面板的显示效果。
进一步的，主像素110和次像素120的混合伽马响应等效于预设伽马响应。
在显示面板中，分别以主像素110和次像素120模拟图7中所示的A部分和B部分，以增大显示面板的可视角，减小色偏。具体的，主像素110的驱动亮度大于主像素110的原始亮度，次像素120的驱动亮度小于次像素120的原始亮度。在数据线上驱动信号Dn的作用下，主子像素111和次子像素121中的液晶发生偏转，导致透光率发生变化，从而显示出不同的亮度。然而，由于液晶光电特性的影响，若直接根据最初的画面信号确定驱动信号，那么驱动信号和最终显示的亮度之间具有非线性的伽马响应。因此，在驱动过程中，需要对最初的画面信号进行反伽马校正，得到校正后的驱动信号，以补偿显示面板的非线性特性，实现无失真的显示。如图8所示，在对最初的画面信号进行反伽马校正时，根据与显示面板的伽马响应对应的伽马值确定反伽马校正过程中的校正伽马值，具体的，校正伽马值和伽马值之间通常呈倒数关系。伽马值反映了显示面板本身的特性。其中，第一伽马值γ1对应于正常显示状态，典型的第一伽马值γ1为2.2～2.5，常用的第一伽马值γ1为2.2；第二伽马值γ2对应于显示偏亮的显示状态，且第二伽马值γ2小于第一伽马值γ1；第三伽马值γ3对应于显示偏暗的显示状态，且第三伽马值γ3于第一伽马 值γ1。因此，通过选择合适的第二伽马值γ2和第三伽马值γ3，使主像素110和次像素120的混合伽马响应等效于预设伽马响应，即第一伽马值γ1对应的伽马响应，以改善显示效果。
如图3和图4所示，主像素110和次像素120交叉排布，也就是说，主像素110的上、下、左、右相邻的像素均为次像素120，次像素120的上、下、左、右相邻的像素均为主像素110。当然，在另一些具体示例中，也可以根据视角将显示面板分为不同的显示区域，在偏视角对应的显示区域中设置包括主像素110和次像素120的像素组100；而在正视角对应的显示区域中，直接按照范例所示的方式驱动各像素。
在本申请的一实施例中，如图3所示，显示面板还包括多条扫描线300，扫描线300沿横向延伸，且扫描线300沿纵向排布；同一主像素110中，主子像素111沿纵向排布且与同一数据线200电连接，各主子像素111分别与不同的扫描线300电连接；同一次像素120中，次子像素121沿纵向排布且与同一数据线200电连接，各次子像素121分别与不同的扫描线300电连接。在本实施例中，每一像素中的各子像素是沿纵向排布的，对应于每一像素，至少需要两条扫描线分别实现扫描驱动(图中所示为三条扫描线分别驱动三个子像素)，而同一像素中的各子像素共用数据线。由于显示面板中扫描线的成本往往低于数据线的成本，因此，这种驱动方式能够减少显示面板中所需的数据线的数量，从而降低显示面板的成本。
进一步的，相邻的主子像素111和次子像素121分别与不同的数据线200电连接。在图3所示的情形中，由于每一主像素110包括三个主子像素111，每一次像素120包括三个次子像素121，因此，在同一列上，每间隔三个相应的子像素，下一子像素连接到相同的数据线上，而间隔中的三个子像素镰刀到另一数据线上。通过控制相邻主子像素111和次子像素121分别与不同的数据线200电连接，那么，以主像素110或次像素120为单位，显示面板是采用点反转的方式驱动的，从而有助于避免显示面板的极化，减小公共电压的偏移，改善显示面板的显示效果。
在本申请的另一实施例中，如图9所示，显示面板还包括多条扫描线300，扫描线300沿横向延伸，且扫描线300沿纵向排布；同一主像素110中，主子像素111沿横向排布且与同一扫描线300电连接，各主子像素111分别与不 同的数据线200电连接；同一次像素120中，次子像素121沿横向排布且与同一扫描线300电连接，各次子像素121分别与不同的数据线200电连接。在本实施例中，每一像素中的各子像素是沿横向排布的，对应于每一像素，至少需要两条数据线分别实现驱动(图中所示为三条数据线分别驱动三个子像素)，而同一像素中的各子像素共用扫描线。由于在一个像素中，子像素与数据线一一对应，因此有助于进一步降低数据线上的驱动信号Dn的频率，从而减小电路功耗和热效应，同时给予子像素充分的充电时间，改善显示面板的显示效果。
进一步的，如图10所示，相邻的像素组100中，各对应位置上的主子像素110或次子像素120的驱动极性相反。也就是说，在本实施例中，以像素组100为单位，显示面板采用点反转的方式驱动，以避免显示面板的极化，减小公共电压的偏移。而在两个相邻的像素组100内部，相对位置相同的主子像素和主子像素的驱动极性相反，相对位置相同的次子像素和次子像素的驱动极性相反。
本申请还提出一种显示面板，如图3和图9所示，显示面板包括多个像素组100，多条数据线200和多条扫描线300，像素组100包括主像素110和次像素120，主像素110和次像素120交叉排布，主像素110包括主子像素111，次像素120包括次子像素121，主子像素111和次子像素121呈矩形阵列状排布，且位于同一列上的主子像素111和次子像素121形成一子像素列，位于同一行上的主子像素111和次子像素121形成一子像素行；数据线200沿纵向延伸，且数据线200沿横向排布，数据线200与子像素列沿横向相间排布；扫描线300沿横向延伸，且扫描线300沿纵向排布，扫描线300与子像素行沿纵向相间排布；其中，主像素110的驱动亮度大于主像素110的原始亮度，次像素120的驱动亮度小于次像素120的原始亮度，且主像素110和次像素120的混合伽马响应等效于预设伽马响应；一数据线200与相邻两子像素列中驱动极性相同的主子像素111和次子像素121电连接，且一主子像素111仅与一数据线200电连接，一次子像素121仅与一数据线200电连接。
本申请还提出一种显示装置，显示装置包括显示面板以及驱动单元，驱动单元与数据线电连接，驱动单元设置为输出驱动信号至数据线上，驱动单元还与显示面板的扫描线电连接，该显示面板的具体结构参照上述实施例， 在此不再一一赘述。
以上所述仅为本申请的可选实施例，并非因此限制本申请的专利范围，凡是在本申请的申请构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
