具体实施方式
体现本公开特征与优点的典型实施例将在以下的说明中详细叙述。应理解的是本公开能够在不同的实施例上具有各种的变化，其皆不脱离本公开的范围，且其中的说明及附图在本质上是作说明之用，而非用以限制本公开。
在对本公开的不同示例性实施方式的下面描述中，参照附图进行，所述附图形成本公开的一部分，并且其中以示例方式显示了可实现本公开的多个方面的不同示例性结构、系统和步骤。应理解，可以使用部件、结构、示例性装置、系统和步骤的其他特定方案，并且可在不偏离本公开范围的情况下进行结构和功能性修改。
为了提高显示面板的屏占比，相关技术中提出了一种屏下摄像头的方案，即将摄像头移至显示面板的屏幕下方，但是如果把摄像头放到显示面板的屏幕下方，为了能够得到较好的成像效果，那么屏幕的透光率至少需要在80％以上，此时需要大幅度降低摄像头上方的屏幕的像素密度。但是，降低该显示面板对应摄像头位置的局部像素密度来增加局部的屏幕透光率，该降低了像素密度的局部称之为局部透明区域(下文中也可以称之为第一显示区域)，由于该局部透明区域的像素密度下降，会导致该局部透明区域的亮度比其周围区域(下文中称之为第二显示区域或者正常区域)的亮度下降明显。
图1是示出根据本公开实施例的一种显示面板的驱动方法的流程图。
本公开实施例中，所述显示面板可以包括具有第一像素密度的第一显示区域和具有第二像素密度的第二显示区域，所述第二像素密度大于所述第一像素密度。
在示例性实施例中，所述第一显示区域可以包括至少一个显示单元，每个显示单元包括至少一个第一像素和至少一个空像素，每个第一像素包括N个子像素和M个子像素，其中，N为大于等于1的正整数，M为大于等于0的整数。
在下面的实施例中，以N＝3，即每个第一像素包括3个子像素，例如一个第一子像素R，一个第二子像素G1和一个第三子像素B；且M＝0或者1为例进行举例说明，即每个第一像素只包括一个第一子像素R，一个第二子像素G1和一个第三子像素B；或者每个第一像素还包括一个第四子像素(该第四子像素可以为R2，G2，B2中的任意一种)。但本公开并不限定于此，例如N还可以等于4或者更大的数值，M还可以等于2或者更大的数值。
在本公开中，所谓的“空像素”物理上并不存在像素，也无法用于显示信息。例如，在图3中，第一显示区域310内的虚线所限定的空间即代表所谓的“空像素”。
本公开实施例中，每个显示单元所包括的第一像素和空像素的个数由所述第一显示区域的第一像素密度与所述第二显示区域的第二像素密度的像素比例确定，例如，在下面的实施例中，均以所述像素比例为1:4为例，即相同面积内，所述第二显示区域具有4个第二像素，所述第一显示区域具有1个第一像素，此时，每个显示单元内包括3个空像素。但本公开并不限定于此，具体的像素比例可以根据实际需求而定。
在示例性实施例中，所述第二显示区域包括多个第二像素，每个第二像素包括N个子像素。
在下面的实施例中，以N＝3，即每个第二像素包括3个子像素，例如一个第一子像素R，一个第二子像素G和一个第三子像素B为例进行说明。但本公开并不限定于此，例如，N还可以为4或者更大的数值。
在示例性实施例中，所述M个子像素中包括至少一个绿色子像素。例如，图3中的第一显示区域310中的每个显示单元的第一像素除了包括第一子像素R、第二子像素G1和第三子像素B，还包括第四子像素G2。这是因为绿色对亮度的提升效果较好。
但本公开并不限定于此，例如，所述M个子像素中还可以包括至少一个红色子像素(R2)和/或蓝色子像素(B2)。
在示例性实施例中，所述M个子像素的数据线分别连接至驱动芯片位于所述第一显示区域内的任意一条空闲数据通道。
当M不为0时，即第一显示区域内的每个第一像素相比于第二显示区域内的每个第二像素会多M个子像素，这多出的M个子像素的数据线需要连接到驱动芯片的数据通道上以便于接收驱动芯片发送的数据(Data)信号用于显示图像，而由于第一显示区域的第一像素密度小于第二显示区域的第二像素密度，因此，假设显示面板在第二显示区域内每行包括n(n为大于等于1的正整数)个第二像素，则驱动芯片包括n*N条数据通道，每条数据通道与每行中的第二像素的各个子像素的数据线一一对应的物理连接。
此时，对应于第一显示区域内的数据通道一部分用于物理连接每行中的第一像素的N个子像素的数据线，另一部分称之为空闲数据通道，此时，可以将每个第一像素的另外M个子像素的数据线物理连接至任意一条空闲数据通道，如图4所示，以A1-A4组成的显示单元为例，第一像素A4包括第一子像素R，第二子像素G1、第三子像素B以及第四子像素G2，而第二像素包括第一子像素R，第二子像素G、第三子像素B，此时，第一显示区域310对应于A4这个第一像素这一行而言，存在前一个第二像素的R、G、B三个子像素的三条空闲数据通道以及后一个第二像素的R、G、B三个子像素的三条空闲数据通道，此时，可以将第一像素A4的第四子像素G2的数据线物理连接至所述前一个第二像素的R、G、B三个子像素的三条空闲数据通道以及后一个第二像素的R、G、B三个子像素的三条空闲数据通道中的任意一条。
在示例性实施例中，所述M个子像素中至少一个子像素的数据线连接至邻近所述至少一个子像素的空闲数据通道。
为了降低物理连线的复杂度，本公开实施例中，可以将第一像素中的M个子像素中的任意一个子像素的数据线物理连接至最靠近它的空闲数据通道，例如，图4所示的实施例中，将第一像素A4的第四子像素G2的数据线物理连接至前一个第二像素的B子像素对应的驱动芯片的数据通道。
如图1所示，本公开实施方式提供的显示面板的驱动方法可以包括以下步骤。
在步骤S110中，接收第一色域输入数据。
例如，所述第一色域输入数据为输入图像的RGB，但本公开并不限定于此。
在步骤S120中，将对应于所述第一显示区域的第一色域输入数据转换成第二色域中间数据。
例如，所述第二色域中间数据为YUV，但本公开并不限定于此。
在示例性实施例中，所述第一显示区域可以包括第一显示单元，所述第一显示单元可以包括至少一个第一像素；所述第二色域中间数据可以包括亮度数据(Y)、第一色度数据(U)和第二色度数据(V)。
在示例性实施例中，所述将对应于所述第一显示区域的第一色域输入数据转换成第二色域中间数据，可以包括：根据对应于所述第一显示单元的第一色域输入数据获得所述亮度数据；根据对应于所述至少一个第一像素的第一色域输入数据获得所述第一色度数据和所述第二色度数据。
在步骤S130中，将所述第二色域中间数据转换成第一色域输出数据。
例如，通过对输入图像的RGB进行处理，可以获得对应于输出图像的YUV数据，然后再将对应于输出图像的YUV数据转换成对应于输出图像的RGB数据；或者通过对输入图像的RGB进行处理，可以获得对应于输出图像的YUV数据，然后再将对应于输出图像的YUV数据转换成对应于输出图像的RG1BG2数据。
在步骤S140中，将所述第一色域输出数据转换成驱动所述第一显示区域的驱动信号。
在步骤S140中获得驱动信号是用于驱动显示面板的第一显示区域的，通常，所述驱动信号可以是LVDS信号(Low-Voltage Differential Signaling，低电压差分信号)。将所述驱动信号输出至显示面板的时序控制电路(Timer Control Register，TCON)。
本公开实施方式公开的显示面板的驱动方法，通过提升局部透明区域的亮度，能够实现整屏亮度均匀，解决了相关技术中由于局部透明区域像素密度下降，导致在相同画面下，局部透明区域亮度较周围区域下降，从而出现明显的暗区，影响整体视觉效果的技术问题。
下面分别结合图2-7对上述显示面板的驱动方法进行举例说明。
图2是示出根据本公开实施例的一种显示面板的结构示意图。
全屏显示技术中，采用屏下摄像头方案时，为了提高对应摄像头的显示面板的局部区域的透光率，会降低显示面板对应摄像头的局部区域的像素密度实现局部透明。
如图2所示，本公开实施方式提供的显示面板200可以包括第一显示区域210和第二显示区域220。
其中，第一显示区域210为透明区域，以便于设置于显示面板后侧的摄像头通过所述透明区域采集图像。
在本实施例中，“前”是指显示面板200中显示信息的一侧所面向的方向，“后”是指与“前”相反的方向。
第二显示区域220为非透明区域，即正常区域，所述非透明区域可以包括显示模块和背光模块。
需要说明的是，如图2所示，为透明区域与正常区域的位置关系，第一显示区域210设置于显示面板200的上端中间位置，且为圆形，但本公开并不限定于此，第一显示区域210可以根据实际需求设置于显示面板200的任意合适位置，且可以设计为任意形状。
为了提升画面显示质量以及简化显示面板制作工艺，第一显示区域210可以形成在显示面板200的顶部。具体地，第一显示区域210可以极其靠近显示面板200的边缘。
为了方便用户使用终端摄像头拍摄，根据用户使用终端的习惯，如图2所示，第一显示区域210形成在显示面板200的顶端中部，第一显示区域210可以极其靠近显示面板200的边缘。
在其他实施例中，第一显示区域210可以形成在显示面板200的顶端侧部，第一显示区域210可以极其靠近显示面板200的边缘。
为美化显示面板，提升画面显示质量、降低显示面板制作工艺，还可以将第一显示区域210设置在显示面板200的侧部与顶部相交处。
第一显示区域210的轮廓形状可以有多种，例如，可以为圆弧形、圆角矩形、圆角方形等中的一种或多种。
图3是示出根据本公开实施例的另一种显示面板的结构示意图。
如图3所示，本公开实施方式提供的显示面板300可以包括第一显示区域310和第二显示区域320。
第一显示区域310可以包括至少一个显示单元，图3中仅示出了4个显示单元用于示意说明，但本公开并不限定于此。例如A1-A4组成一个显示单元，其中，A1、A2和A3为空像素，A4为第一像素。
图3所示的实施例中，每个第一像素包括一个第一子像素R、一个第二子像素G1、一个第三子像素B和一个第四子像素G2。
继续参考图3，第二显示区域320包括多个第二像素，每个第二像素包括一个第 一子像素R、一个第二子像素G和一个第三子像素B。
图3为第一显示区域310的第一像素密度与第二显示区域320的第二像素密度示意图。图3中第一像素密度与第二像素密度的像素比例为1:4，在显示相同灰阶时，第一显示区域310发光像素数量只有第二显示区域320的1/4，故亮度会存在相似比例的差异，如若不做调整，图3中的显示面板300会出现一个暗区，本公开通过把第一显示区域310采用RG1BG2的形式来实现提升第一显示区域310亮度的目的。
本公开的思路遵守人眼视觉系统定量，即一个同样大小的区域，亮两个灯和亮一个灯但亮度是之前两倍的情况，人眼是很难区别的，不会出现闪烁，且成本低。
本公开实施方式公开的显示面板，局部透明区域采用图3所示的RG1BG2的像素排列，加入G2子像素来提高单个像素的亮度，最终达到局部透明区域亮度增加的目的。通过提升局部透明区域的亮度，能够实现整屏亮度均匀，解决了相关技术中由于局部透明区域像素密度下降，导致在相同画面下，局部透明区域亮度较周围区域下降，从而出现明显的暗区，影响整体视觉效果的技术问题。
图4是示出基于图3所示显示面板的显示设备的结构示意图。
如图4所示，本公开实施方式提供的显示设备除了包括上述图3所示的显示面板，还包括驱动装置400。其中，驱动装置400的输出端与显示面板300的输入端相连。
图4所示实施例中，驱动装置400包括与第二显示区域320内各行第二像素的各子像素(这里以每个子像素包括一个第一子像素R、一个第二子像素G和一个第三子像素B为例进行说明)的数据线物理连接的多条数据通道410。
所述多条数据通道410在第一显示区域310内对应各行的空像素的数据通道称之为空闲数据通道，例如数据通道411。
在下面的实施例中，所述驱动装置400可以集成于显示设备的驱动芯片(驱动IC，Integrated Circuit，集成电路)中，所述驱动IC可以用于对显示面板300的信息显示进行控制。但本公开并不限定于此。所述驱动芯片可以设置于显示设备的不显示信息的非显示区域。
在示例性实施例中，所述显示设备还可以包括视频输入模块，该视频输入模块例如可以通过HDMI(High Definition Multimedia Interface，高清晰度多媒体接口)接收端口接收视频文件，经过SOC(System-on-a-Chip)的处理后，利用Vbyone发射端口输送至所述驱动装置。或者，可以直接将图像文件输送至所述驱动装置。
显示面板300用于对电子文件进行画面显示，显示面板300可显示图像、文本等信息。显示面板300可包括显示信息的前侧，以及位于前侧的相对侧的后侧。
在示例性实施例中，第一显示区域310和第二显示区域320可以配合显示一副完整的画面。比如，显示一副图像时，第一显示区域310可以显示图像的一部分，第二显示区域320可以显示图像的剩余部分。
在示例性实施例中，第一显示区域310可以为具有独立显示功能的透明显示屏。 比如，可以为透明的OLED显示屏或者LCD显示屏。
在示例性实施例中，所述显示设备还可以包括：摄像头，所述摄像头可以设置于显示面板300后侧，且所述摄像头对应第一显示区域310的位置。
在摄像头设置在第一显示区域310的后侧时，外界光信号可以透过第一显示区域310射入摄像头的出光面，当终端接收到拍摄指令时，摄像头可以感应被拍摄物体发射的光信号，再根据感应到的光信号成像，从而采集到被拍物体的图像。
为了能够使得摄像头能够采集到外界图像，第一显示区域310为透明区域。这样外界光信号便可以通过透明的第一显示区域310入射到摄像头的出光面，摄像头便可以成功采集外界图像。其中，该第一显示区域310的透明度可以由本领域技术人员或者生产厂商进行设置。
本公开实施例中，根据第一显示区域310的透明度可以设定第一显示区域310和第二显示区域320之间的像素比例。例如，第一显示区域310所需的透明度越高，则第一显示区域310的第一像素密度越低，相应的像素比例越小，例如可以为1:6，1:8等等。反之，第一显示区域320所需的透明度越低，则第一显示区域320的第一像素密度越高，相应的像素比例越大。
本公开实施例中，第一显示区域310的面积小于第二显示区域320的面积。其中，第一显示区域310的面积大小与摄像头的出光面大小相关。比如，摄像头的出光面越大，为了尽可能扩大摄像头视角，那么该第一显示区域310的面积也就设置的越大。
下面结合图4所示显示设备对上述显示面板的驱动方法进行阐述。
实现方式如图4所示，第一显示区域310的第一像素的G2子像素数据线物理连接到驱动IC第二显示区域320的前一个像素的B通道411上。这里可以将上述显示面板的驱动方法集成到驱动IC中来实现。
当驱动IC检测到第一显示区域310的第一色域输入数据Data后会进行RGB至YUV的转换(其中，Y为亮度数据，U、V分别为第一色度数据和第二色度数据)。
对应图4所示的显示面板300的结构，以A1-A4组成的显示单元为例进行说明。将输入的所述第一色域输入数据中对应A1-A4的四个像素的RGB(假设分别为RA1、GA1、BA1；RA2、GA2、BA2；RA3、GA3、BA3；RA4、GA4、BA4)进行累加获得新的R’G’B’：
R’＝RA1+RA2+RA3+RA4
G’＝GA1+GA2+GA3+GA4
B’＝BA1+BA2+BA3+BA4
通过下面的转换公式可以获得亮度数据Y：
Y＝0.30R’+0.59G’+0.11B’
同时，将输入的所述第一色域输入数据中对应第一像素A4的RA4、GA4、BA4进行转换分别获得第一色度数据U和第二色度数据V：
YA4＝0.30RA4+0.59GA4+0.11BA4
U＝0.493(BA4-YA4)
V＝0.877(RA4-YA4)
将上述YUV组合成所述第二色域中间数据。再通过以下公式将YUV转换成对应第一像素A4的RG1BG2四个子像素的第一色域输出数据：
Figure PCTCN2019087283-appb-000001
即驱动IC接收到与第一显示区域310对应的RGB数据后，通过将对应显示单元内的各个像素(包括空像素和第一像素)的RGB数据进行累加，将累加后的RGB进行转换获得的亮度数据Y(大约为第一像素的亮度数据YA4的四倍，具体倍数取决于像素比例，但这里的倍数仅是一个大约数，后续还可以根据需要，对显示面板panel的亮度效果进行主观评价后进行微调)作为第一像素的亮度数据，即第一显示区域310内的各第一像素的亮度同时综合了其上、左和左上的空像素以及其自身的亮度，而同时保持对应第一像素的U和V数据保持不变，即通过这样的亮度调整，可以把第一显示区域310的第一像素的亮度调整到和正常区域的第二像素的亮度相当的水平，提升了局部透明区域亮度，这样就能达到显示面板300的局部透明区域与周围区域亮度相当的效果。测试局部透明区域及相邻正常区域的亮度，当亮度差异≤4％时，人眼无法察觉亮度变化，即可判定亮度相当，从而达到全屏亮度一致的最终目的。
本公开实施方式提供的显示设备，解决了全屏显示技术中，屏下摄像头技术导致的屏幕区域亮度不均的技术问题。
图5是示出根据本公开实施例的又一种显示面板的结构示意图。
如图5所示，本公开实施方式提供的显示面板500可以包括第一显示区域510和第二显示区域520。
第一显示区域510包括至少一个显示单元，这里还是以像素比例为1:4为例进行说明。例如A1-A4组成一个显示单元，每个显示单元包括三个空像素A1-A3和一个第一像素A4。与上述图3所示实施例不同的是，这里每个第一像素A4包括一个第一子像素R、一个第二子像素G和一个第三子像素B。
第二显示区域520包括多个第二像素，每个第二像素包括一个第一子像素R、一个第二子像素G和一个第三子像素B。
图6是示出基于图5所示显示面板的显示设备的结构示意图。
如图6所示，本公开实施方式提供的显示设备除包括上述图5所示的显示面板，还包括驱动装置600，驱动装置600包括多条数据通道610，分别电连接第二显示区 域520的各行的第二像素的各个子像素。
所述多条数据通道610中对应第一显示区域510内的各行空像素的数据通道为空闲数据通道，例如空闲数据通道611，即在第一显示区域510内，未与任何一个子像素的数据线进行物理连接。
由于图5和6所示实施例中，第一显示区域510内的第一像素与第二显示区域520内的第二像素的子像素个数相同，此时不存在多余的没有连接相应驱动IC的数据通道的子像素，也就不需要将第一像素的子像素的数据线与空闲数据通道进行物理连接。
下面结合图6所示显示设备对上述显示面板的驱动方法进行阐述。
实现方式如图6所示，这里可以将上述显示面板的驱动方法集成到驱动IC中来实现。
当驱动IC检测到第一显示区域510的第一色域输入数据Data后会进行RGB至YUV的转换(其中，Y为亮度数据，U、V分别为第一色度数据和第二色度数据)。
对应图6所示的显示面板500的结构，以A1-A4组成的显示单元为例进行说明。将输入的所述第一色域输入数据中对应A1-A4的四个像素的RGB(假设分别为RA1、GA1、BA1；RA2、GA2、BA2；RA3、GA3、BA3；RA4、GA4、BA4)进行累加获得新的R’G’B’：
R’＝RA1+RA2+RA3+RA4
G’＝GA1+GA2+GA3+GA4
B’＝BA1+BA2+BA3+BA4
通过下面的转换公式可以获得亮度数据Y：
Y＝0.30R’+0.59G’+0.11B’
同时，将输入的所述第一色域输入数据中对应第一像素A4的RA4、GA4、BA4进行转换分别获得第一色度数据U和第二色度数据V：
YA4＝0.30RA4+0.59GA4+0.11BA4
U＝0.493(BA4-YA4)
V＝0.877(RA4-YA4)
将上述YUV组合成所述第二色域中间数据。再通过以下公式将YUV转换成对应第一像素A4的RGB三个子像素的第一色域输出数据：
Figure PCTCN2019087283-appb-000002
即驱动IC接收到与第一显示区域310对应的RGB数据后，通过将对应显示单元 内的各个像素(包括空像素和第一像素)的RGB数据进行累加，将累加后的RGB进行转换获得的亮度数据Y(大约为第一像素的亮度数据YA4的四倍，具体倍数取决于像素比例，但这里的倍数仅是一个大约数，后续还可以根据需要，对显示面板panel的亮度效果进行主观评价后进行微调)作为第一像素的亮度数据，即第一显示区域510内的各第一像素的亮度同时综合了其上、左和左上的空像素以及其自身的亮度，而同时保持对应第一像素的U和V数据保持不变，即通过这样的亮度调整，可以把第一显示区域510的第一像素的亮度调整到和正常区域的第二像素的亮度相当的水平，提升了局部透明区域亮度，这样就能达到显示面板500的局部透明区域与周围区域亮度相当的效果。测试局部透明区域及相邻正常区域的亮度，当亮度差异≤4％时，人眼无法察觉亮度变化，即可判定亮度相当，从而达到全屏亮度一致的最终目的。
图7是示出根据本公开实施例的另一种显示面板的驱动方法的流程图。
可以将显示面板的驱动方法集成于驱动IC内部透明区域数据处理模块，透明区域数据处理模块接收外部Data，检测是否为透明区域数据；如果为透明区域数据，则进行RGB至YUV转换，调整透明区域的目标亮度；然后再进行YUV至RG1BG2转换，最后进行数据输出，输出Data至显示面板的透明区域进行显示。
如果不为透明区域数据，则直接进行数据输出。
需要说明的是，上述图3和图5所示的显示面板结构仅用于举例说明，可以根据相同的发明构思对显示面板的结构进行各种变形，例如第一显示区域的每个显示单元所包括的空像素和第一像素的个数，每个第一像素所包括的子像素数目以及各个子像素可以选择任意的颜色，第一像素和空像素的位置布局；第一显示区域和第二显示区域的像素比例；第二显示区域的第二像素所包含的子像素个数可以与第一显示区域的第一像素的子像素个数相同，例如第二像素可以为RG1BG2，同时第一像素也可以为RG1BG2；第二显示区域的第二像素所包含的子像素个数也可以与第一显示区域的的第一像素的子像素个数不同。当上述显示面板的结构进行变形了，可以对上述显示面板的驱动方法中的亮度调整计算公式进行相应的改变。
图8是示出根据本公开实施例的一种显示面板的驱动装置的模块示意图。
