Description

一种显示面板及其控制方法、显示装置 技术领域
本发明涉及显示技术领域，尤其涉及一种显示面板及其控制方法、显示装置。
 背景技术
随着移动便携设备的普及化程度越来越高，高屏占比屏幕由于能给予用户更好视觉体验而成为手机、平板等电子设备的未来发展趋势。屏占比用于表示屏幕和手机前面板面积的相对比值，其反映了用户对于移动设备的视觉体验，如何实现100%的屏占比的显示效果是目前行业亟待解决的难题。
但是对于手机等便携设备而言，除了显示屏幕以外，还需在前面板顶部位置放置一些电子元件如摄像头、闪光灯、光线传感器等，这些器件需要从面板正面采光，由于传统屏幕会对上述电子元件进行遮挡，目前行业内的普遍做法是将前面板做异形切割，裁剪掉部分屏幕以实现透光，以此保证电子元件的正常工作。上述做法在破坏整块屏幕的完整性的同时，也始终无法做到100%屏占比的全面显示。
另一种全面屏的解决方案是将电子元件如前置摄像头做到单独的机械模块上作为独立控制的部件，默认隐藏在机身内部，当用户有拍照、拍视频等需求的时候，摄像头会响应系统的指令自动弹出或手动滑出，即所谓“弹出式”或“滑盖式”设计。然而，受限于机械结构的因素，其摄像头弹出时间缓慢，其开启速度落后于传统意义的摄像头；其次由于机械结构受到装配工艺的影响，使得弹出功能模块与显示面板本体之间存在间隙，易受到外界粉末灰尘侵入，不能做到良好的防水防尘；再者弹出式设计其机械结构存在较高的故障率，滑盖式设计易于出现人为用力过大导致的排线损坏的问题，因此该方案仍影响了用户对产品的使用体验。
因此，如何在不破坏屏幕完整性，又不引入新的机械结构的前提下，实现全面屏显示，是本领域亟待解决的问题。

一种显示面板，如图1至图3所示，所述显示面板包括显示单元10和背光模块20。
具体的，所述显示单元10设置于所述背光模块20上，用于显示画面；所述显示单元10包括主显示区11和功能附加区12，所述功能附加区12的至少一部分被所述主显示区11围绕，所述主显示区11为常规显示区，功能附加区12为透明显示区。
其中，所述功能附加区12用于对应设置电子元件30，且当电子元件30不工作时，所述主显示区11和所述功能附加区12均可用于显示画面；所述电子元件30工作时，此时，所述主显示区11可以正常显示画面，所述功能附加区12不显示画面且为透明状态，以用于为电子元件30提供采光通道，从而实现电子元件30的功能。
需要说明的时，当电子元件30不工作时，所述主显示区11和所述功能附加区12可共同显示一个画面，也可分别显示不同的画面。

需要说明的是，所述第一光源块41与所述第二光源块42独立控制即所述第一光源块41的开关控制端与所述第二光源块42的开关控制端非电连接且单独控制，是指第一光源块41的开关控制端和第一光源块41的开关控制端是两个独立控制的开关控制端，即第一光源块41的开关控制端在控制第一光源块41的开启和关闭时，不会对第二光源块42的开启或关闭状态造成影响。同理第二光源块42的开关控制端在控制第二光源块42的开启和关闭时，不会对第一光源块41的开启或关闭状态造成影响。
第一光源块41与第二光源块42相互独立控制，从而使得主显示区11和功能附加区12可以同时显示画面，又可以实现主显示区11正常显示时，功能附加区12不显示画面，或者功能附加区12正常显示画面，主显示区11不显示画面。
具体的，参见图2，所述显示面板还包括背光驱动模块82以及屏驱动模块83。
具体的，所述背光驱动模块82与所述第一光源块41以及所述第二光源块42电连接，用于当接收到第一控制信号时，控制所述第一光源块41开启，即通过所述第一光源块41的开关控制端开启所述第一光源块41。
其中，所述背光驱动模块82还用于当接收到第二控制信号时，控制所述第二光源块42开启，即通过所述第二光源块42的开关控制端开启所述第二光源块42。
只需要主显示区11进行显示时，背光驱动模块82接收到第一控制信号，背光驱动模块82控制第一光源块41打开，为主显示区11提供光源；只需要功能附加区12提供显示时，背光驱动模块82接收到第二控制信号，背光驱动模块82控制第二光源块42打开，为功能附加区12提供光源；需要主显示区11和功能附加区12同时显示时，背光驱动模块82同时接收到第一控制信号和第二控制信号，背光驱动模块82控制第一光源块41和第二光源块42同时打开。
具体的，所述背光模块20上设置有与功能附加区12对应的第一通孔23，所述第一通孔23贯穿所述背光模块20，以为与功能附加区12对应设置的电子元件30提供采光通道。
当电子元件30不工作时，所述第二光源块42为所述功能附加区12提供光源，以使所述主显示区11与所述功能附加区12共同显示画面；当电子元件30工作时，第二光源块42关闭，功能附加区12不显示画面，利用第一通孔23为电子元件30提供采光通道。
其中，所述第二光源块42设置在靠近所述第一通孔23处。
具体的，所述背光模块20还包括用于设置第一光源块41的第一背光区21和用于设置第二光源块42的第二背光区22，所述第二背光区22的至少一部分被所述第一背光区21围绕，所述第一通孔23位于所述第二背光区22。
具体的，所述显示单元10包括相对设置的第一基板13和第二基板14、以及设置于所述第一基板13和第二基板14之间的液晶层15。
其中，第一基板13可以为阵列基板，第二基板14可以为彩膜基板。
具体的，所述显示单元10还包括设置在所述第一基板13与背光模块20之间的下偏光片17，以及，设置在所述第二基板14远离所述液晶层15的一侧上的上偏光片16。
在一实施方式中，所述液晶层15包括位于所述主显示区11的第一液晶层151以及位于所述功能附加区12的第二液晶层152，所述第二液晶层152中的液晶为散射型液晶。
在一实施方式中，所述第一液晶层151设置于所述主显示区11处，所述第二液晶层152对应设置在所述功能附加区12处。具体地讲，所述第一液晶层151设置在所述显示单元10除去所述功能附加区12的其他区域上。
具体的，所述屏驱动模块83用于当接收到液晶控制信号时，控制所述液晶层15中的液晶旋转。
进一步的，所述第一液晶层151与所述第二液晶层152相互独立，且可由屏驱动模块83单独控制，从而实现功能附加区12与主显示区11可以单独显示画面，也可同时显示画面。
进一步的，所述背光驱动模块82控制所述第二光源块42关闭时，所述屏驱动模块83控制所述第二液晶层152中的液晶旋转至透明状态，以为电子元件30的采光提供采光通道；所述背光驱动模块82控制所述第二光源块42开启时，所述屏驱动模块83驱动所述第二液晶层152中的液晶旋转至散射状态，以对第二光源块42发出的光线进行散射，从而为功能附加区12显示画面提供均匀的光照。
需要说明的是，需要主显示区11显示画面时，背光驱动模块82接收到第一控制信号，背光驱动模块82控制第一光源块41开启时，所述屏驱动模块83接收到对应的液晶控制信号，以控制所述第一液晶层151中的液晶旋转至显示状态，从而为主显示区11显示画面提供均匀的光照。
本一实施方式中，所述第一液晶层151可以为现有技术的普通液晶，所述第一液晶层151包括多个液晶分子，所述液晶分子包括联苯液晶、苯基环己烷液晶或酯类液晶。所述第二液晶层152的材料包括散射型液晶；所述散射型液晶包括多个液晶分子和聚合物，可实现透明态和散射状态的切换，聚合物可以为离子型有机电解质材料。
所述第一液晶层151（即普通液晶）在施加电压后液晶分子发生旋转，屏驱动模块83通过控制施加的电压大小控制液晶分子的旋转角度，从而控制光的透过率实现灰阶显示；所述第二液晶层152（即散射型液晶）中由于增加了聚合物，二者折射率不同，通过电压控制液晶和聚合物的表面产生折射率差，使得光线透过或者在二者表面发生散射，因此可以实现透明状态或者散射状态。在透明态下可以透光，散射状态下实现光线的散射进而用于显示画面。
所述第二液晶层152使用的具体过程为：液晶与聚合物具有相同的各向异性的介电常数，不加电压或电压低于阈值电压时，液晶分子呈水平排列，与其内聚合物材料不存在折射率差，因此不发生散射；当施加的电压高于阈值电压时，液晶分子发生旋转，其方向沿着垂直方向排列，改变了液晶的介电常数的各向异性的特性，因此在液晶和聚合物的表面产生折射率差，光线在此处发生散射，被观察者看到。
在一实施方式中，所述电子元件30包括摄像头、闪光灯、光线传感器、呼吸灯传感器、距离传感器、指纹扫描仪传感器、麦克风传感器或透明天线传感器中的一种或其组合。
需要说明的是，以电子元件30为摄像头为例，不需要摄像头工作时，此时摄像头关闭，所述显示单元10呈画面显示状态以进行画面显示。
需要主显示区11和功能附加区12同时显示时，背光驱动模块82接收到第一控制信号和第二控制信号，所述屏驱动模块83接收到对应的液晶控制信号，此时背光驱动模块82控制第一光源块41和第二光源块42同时打开，第一光源块41为主显示区11的显示提供光源，第二光源块42为所述功能附加区12的显示提供光源，此时，屏驱动模块83控制液晶层15中的液晶旋转，使得第一液晶层151中的液晶呈显示状态，第二液晶层152中的液晶呈散射状态，主显示区11和功能附加区12共同显示画面，显示单元10处于全面屏显示状态。
第二光源块42处于开启状态且需要摄像头工作时，背光驱动模块82接收到第三控制信号，背光驱动模块82控制第二光源块42关闭，第一光源块41正常工作，屏驱动模块83控制第二液晶层152中的液晶旋转至透明状态，此时主显示区11正常显示，功能附加区12呈透明状态，外界光线通过功能附加区12和第一通孔23进入摄像头以完成摄像工作。
通过在与电子元件30相对应的区域设置功能附加区12，利用第二光源块42为功能附加区12提供光源，并利用背光驱动模块82单独控制第一光源块41和第二光源块42的启闭，利用屏驱动模块83根据需求对第二液晶层152中的液晶进行透明状态和散射状态的切换，从而实现功能附加区12进行透明态和画面显示态的切换，可实现在不破坏屏幕完整性，又不引入新的机械结构的前提下，实现全面屏显示效果。
需要说明的是，所述功能附加区12可以位于显示单元10上的任意位置处，所述功能附加区12的形状呈刘海状、美人尖、水滴状、圆形、三角形、矩形或多边形中的任一种。

需要说明的是，屏驱动模块83接收到的液晶控制信号中包含了显示单元10需要显示的画面的预设亮度等信息，当显示单元10中主显示区11或/和功能附加区12实际显示的画面的亮度等信息与预设亮度不符合时，所述屏驱动模块83发送反馈信号给所述背光驱动模块82，背光驱动模块82控制对应光源块进行发光亮度调整，从而使得对应区域处实际显示画面的亮度与预设亮度相符合。
在一实施方式中，参见图3，所述背光驱动模块82包括相互独立的第一驱动模块821和第二驱动模块822，所述第一驱动模块821用于接收第一控制信号并与所述第一光源块41电连接，所述第二驱动模块822用于接收第二控制信号并与所述第二光源块42电连接。
通过相互独立的第一驱动模块821和第二驱动模块822分别对第一光源块41和第二光源块42进行控制，以实现主显示区11和功能附加区12可以同时显示，也可单独显示，从而使得第一光源块41和第二光源块42的控制更加独立简单，避免第一光源块41和第二光源块42的控制相互影响。
需要说明的是，实际实施中，第一光源块41和第二光源块42也可以通过一个驱动模块进行控制。

需要说明的是，印刷电路板84可以为柔性印刷电路板，从而在所述背光驱动模块82等控制元件安装于印刷电路板84上后，弯折印刷电路板84，将所述背光驱动模块82等控制元件弯折至显示单元10靠近背光模块20的一侧上。
在一实施方式中，所述屏驱动模块83设置于所述显示单元10的边缘区域处，并且所述屏驱动模块83靠近所述印刷电路板84设置。
需要说明的是，实际实施中，屏驱动模块83也可以安装于印刷电路板84上。
需要说明的是，屏驱动模块83可以通过印刷电路板84与显示单元10中的像素驱动电极电连接，从而驱动控制液晶旋转。
实施例二：

进一步的，所述第二光源块42位于所述显示单元10的侧部且靠近所述功能附加区12。
具体的，所述背光模块20包括背光板27，所述第一通孔23设置在所述背光板27上，所述第一光源块41设置在所述背光板27上靠近所述显示单元10的边缘处的一侧。

需要说明的是，参见图7，具体实施中，所述第一光源块41可以放置于所述背光板27的底端侧向给光，所述第二光源块42可以放置于所述背光板27的顶端侧向给光，第二光源块42放置在所述背光板27的顶端是优选方式，其他放置方式的实施例均受到本专利的保护。
具体的，所述下偏光片17和所述上偏光片16对应于所述功能附加区12的位置处均设有第二通孔70。
可以理解的是，所述下偏光片17和上偏光片16分别位于所述第一液晶层151的两侧，其作用是提供线偏振光以及实现所述第一液晶层151显示画面的明暗变化。在所述下偏光片17和上偏光片16对应所述第一通孔23的位置进行挖孔，即设置所述第二通孔70，形成无偏光功能的区域，以保证所述第二液晶层152在透明状态下的透光能力。
在一实施方式中，所述第一通孔23的面积小于所述第二通孔70的面积。这样设置可以保证所述第二液晶层152可以全部显示而不被遮挡。
实施例三：
一种显示面板，如图8至图10所示，其与实施例一的不同之处在于：所述第二光源块42围绕所述第一通孔23设置。
其中，所述功能附加区12可以位于显示单元10上的任意位置。功能附加区12既可以实现拍摄效果，也可以实现显示效果。
在一实施方式中，以电子元件30为摄像头为例，功能附加区12的形状为圆形，电子元件30包括镜头31，镜头31的形状为与功能附加区12对应的圆形。
当功能附加区12进行拍摄处理时，镜头31用以获取入射至功能附加区12的光线，以便摄像头实现成像。镜头31位于功能附加区12中心，镜头31的中心轴线与功能附加区12的中心轴线位于同一直线上。功能附加区12、镜头31皆为圆形，镜头31边缘与功能附加区12边缘形成同心圆结构。

当显示面板的功能附加区12用以显示时，第二光源块42发光将功能附加区12区域全部照亮，使得功能附加区12可以显示影像，与主显示区11共同显示画面，此时画面达到全屏幕显示。第二光源块42散发出的光束均匀地为功能附加区12提供光线，避免出现功能附加区12内的光线不集中、不均匀等问题。
另外，由于功能附加区12的设计电路与主显示区11的设计电路有所区别，因而，在功能附加区12的电路进行设计中，可以通过调节面板电压来改变光的透过量进而来改变显示的亮度，进而可以提高显示面板的显示质量。
在一实施方式中，第二光源块42包括的光源的数量优选为4、6、8 ，而本领域技术人员也可以根据光源区222分布范围的大小进行设置光源的数量。

所述导光板25设于所述反射片24上；所述扩散片26设于所述导光板25远离所述反射片24的一侧。
所述导光板25与所述扩散片26的组合，主要是为了将第一光源块41的光扩散至显示单元10，用以提高所述显示单元10的亮度。
其中，所述下偏光片17和所述上偏光片16对应于所述功能附加区12的位置处均设有第二通孔70。
可以理解的是，所述下偏光片17和上偏光片16分别位于所述第一液晶层151的两侧，其作用是提供线偏振光以及实现所述第一液晶层151显示画面的明暗变化。在所述下偏光片17和上偏光片16对应所述第一通孔23的位置进行挖孔，即设置所述第二通孔70，形成无偏光功能的区域，以保证所述第二液晶层152在透明状态下的透光能力。
