请参阅图1和图2，图1为本申请实施例提供的显示面板的结构示意图，图2为本申请实施例提供的显示面板的局部A放大示意图。
本申请实施例中的显示面板20可以包括邻接的第一显示区220和第二显示区240。第一显示区220和第二显示区240可以共同画面，例如，第一显示区220显示预设画面的一部分，第二显示区240显示预设画面剩下的部分。第一显示区220和第二显示区240也可以显示不同的画面。
例如，第二显示区240可以用于显示预设画面，第二显示区240可用于显示电量、时钟或网络状态等任务栏的画面，可以理解的是，第二显示区240可用于显示对于像素要求较低的画面。第二显示区240第一显示区220均可以显示内容，使得显示区域完整，显示面板20的屏占比高，第一显示区220可以围绕第二显示区240设置，第二显示区240的周缘可以都与第一显示区220邻接，即第二显示区240位于第一显示区220中间。第一显示区220也可以部分围绕第二显示区240，第二显示区240的部分边缘与第一显示区220邻接。
其中，第一显示区220和第二显示区240的层叠结构并不相同。图3为本申请实施例提供的第一显示区的层叠结构示意图。
第一显示区220包括第一液晶层221和驱动电路层226，第一液晶层221和驱动电路层226层叠设置，驱动电路层226包括第一驱动单元组2261和第二驱动单元组2262，第一驱动单元组2261用于驱动第一液晶层221。
第一显示区220还可以包括像素电极层222、钝化层223、公共电极层224、平坦层225以及基板227，其中，基板227、驱动电路层226、平坦层225、公共电极层224、钝化层223、像素电极层222以及第一液晶层221依次层叠设置。
基板227可以作为显示面板的承载平台，基板227可以采用玻璃或塑料或树脂或其他材料制成。
驱动电路层226设置于基板227上，驱动电路层226中包括驱动第一显示区220中的第一液晶层221的第一驱动单元组2261，以及驱动第二显示区240中的第二液晶层241的第二驱动单元组2262，每个第一驱动单元组2261包括至少一个薄膜晶体管，每个第二驱动单元组2262包括至少一个薄膜晶体管。
在一些实施例方式中，驱动电路层226包括缓冲层401、多晶硅层402、栅极绝缘层403、栅极404、层间绝缘层405、源极406以及漏极407。其中，缓冲层401设置在基板227上，多晶硅层402设置在缓冲层401上，栅极绝缘层403设置在多晶硅层402上，栅极404设置在栅极绝缘层403上，层间绝缘层405设置在栅极404上，源极406和漏极407设置在层间绝缘层405上，其中，一源极406、一漏极407以及一栅极404构成一薄膜晶体管，驱动电路层226中的第一驱动单元组2261组至少包括一个薄膜晶体管，用于驱动第一显示区220的第一液晶层221。
平坦层225设置于驱动电路层226上，公共电极层224设置于平坦层225上，钝化层223设置于公共电极层224上，像素电极层222设置于钝化层223上，第一液晶层221设置于钝化层223上，为了使得第一驱动单元组可驱动第一液晶层221，设置有贯穿平坦层225、公共电极层224以及钝化层223的第二过孔，在过孔内设置有第二导线，其中，第二导线可以为导电材料制成的导线，诸如ITO电极，第二导线将第一驱动单元组2261的薄膜晶体管中的源极和像素电极层222中对应的像素电极导通，使得薄膜晶体管可以控制像素电极，进而控制像素电极对应的第一液晶层的偏转方向。
第二显示区包括透明连接层，设置在第一显示区的第二驱动单元组可通过透明连接层驱动第二显示区的第二液晶层，请继续参阅图4，图4为本申请实施例提供的第二显示区的层叠结构示意图。
第二显示区240与第一显示区220邻接，第二显示区240包括第二液晶层241和透明连接层246，第二驱动单元组2262通过透明连接层246驱动第二液晶层241。
其中，透明连接层246可以包括透明电极，透明电极用于连接第二驱动单元组中的薄膜晶体管和设置在第二显示区240的像素电极。
第二显示区240还包括像素电极层242、钝化层243、公共电极层244、平坦层245、间隔层247以及基板248，其中，基板248、间隔层247、透明连接层246、平坦层245、公共电极层244、钝化层243、像素电极层242以及第二液晶层241依次层叠设置。
在一些实施方式中，间隔层247设置于基板248上，间隔层247可以与第一显示区220的驱动电路层226同一层设置，透明连接层246设置于间隔层247上，其中，透明连接层246中的透明电极可以与第二驱动单元组2262的源极电性连接。
在一些实施方式中，第一显示区220还包括电性连接层，第二驱动单元组2262通过电性连接层连接透明连接层246。电性连接层可以和透明连接层246位于同一层。透明连接层246还可以设置于电性连接层的上方或下方，直接通过层叠结构电性连接，电性连接层和驱动电路层之间还可以设置有绝缘层，绝缘层设置有第一过孔，电性连接层通过设置于第一过孔内的第一导线和第二驱动单元组2262连接。
其中，为了避免透明连接层246中透明电极产生的电位对第二显示区240显示的干扰，透明连接层246设置于公共电极层224背离像素电极层222的一侧，第二液晶层241设置于像素电极层242背离所述公共电极层224的一侧，平坦层245设置于公共电极层244和透明连接层246之间，具体的，平坦层245设置于透明连接层上，公共电极层224设置于平坦层225上，钝化层223设置于公共电极层224上，像素电极层222设置于钝化层223上，第二液晶层241设置于钝化层223上，为了使第二驱动单元组2262可驱动第二液晶层241，第二显示区240设置有贯穿透明连接层246、平坦层245、公共电极层244以及钝化层243的第三过孔，在第三过孔内设置第三导线，第三导线将第二显示区240的像素电极与透明连接层246内的透明电极连通，第二驱动单元组2262的薄膜晶体管与透明连接层246内的透明电极连通，以控制第二显示区240的像素电极，进而控制第二显示区240的像素电极对应的第二液晶层241的偏转。
需要说明的是，第二显示区240内各层结构均可采用透光材料，以提高第二显示区240的透光率。例如，第二显示区240的基板248、间隔层247、透明连接层246、平坦层245、公共电极层244、钝化层243、像素电极层242都可以采用透光材料制成，因为驱动电路层226中的薄膜晶体管是不透光的，将驱动第二液晶层241的薄膜晶体管均设置在第一显示区220内，提高第二显示区240的透光率。
请继续参阅图2和图5，图5为图2示例中B区域的层叠结构示意图。
第一显示区220包括主显示区231和过渡显示区232，过渡显示区232和第二显示区240临接，为了减小透明连接层246中透明电极的数量以及长度，可以将第二驱动单元组2262设置于过渡显示区232内，将第一驱动单元组2261设置于主显示区231，第二驱动单元组2262设置于过渡显示区232，在一些实施方式中，为了提高过渡显示区232显示画面的品质，过渡显示区232可以同时设置有第一驱动单元组2261和第二驱动单元组2262。
过渡显示区232内各层结构中除了驱动电路层226外都采用透光材料，以提高过渡显示区232的透光率。例如，过渡显示区232的基板227、平坦层225、公共电极层224、钝化层223、像素电极层222都可以采用透光材料制成。驱动电路层226的薄膜晶体管无法采用透光材料，驱动电路层226中除了薄膜晶体管其他部分也可以采用透光材料。可以理解的是，通过提高材料的透光率以及改变布线的排布以过渡显示区232的方案均在本申请的范围内。过渡显示区232的驱动电路层226可以设置有第二驱动单元组2262，第二驱动单元组2262的电路比第一驱动单元组的电路精简，使得第二驱动单元组2262的薄膜晶体管的数量比第一驱动单元组2261的薄膜晶体管的数量少。因为晶体管是不透光的，第二驱动单元组2262的薄膜晶体管越少，过渡显示区232不透光的面积自然更小，可以提高过渡显示区232的透光率，由于过渡显示区232与第二显示区240邻接，可以对第二显示区240进行补光，提高第二显示区240整体的进光量。
在一些实施方式中，第一液晶层221和第二液晶层241上还设置有彩色滤光片和上偏光片，基板227下还设置有下偏光片以及背光模组。
本申请通过透明连接层将设置在第二显示区的第二液晶层与设置在第一显示区的第二驱动单元组电性连接，将不透光的第二驱动单元组设置在第一显示区，增大第二显示区的透光率，摄像装置可以通过第二显示区采集外界光信号以成像。
在一些实施方式中，还可以通过改变第一显示区和第二显示区的像素分布密度以提升第二显示区的透光率，具体的，请结合图6、图7和图8，图6为本申请实施例提供的主显示区的像素分布示意图，图7为本申请实施例提供的过渡显示区的像素分布示意图，图8为本申请实施例提供的第二显示区的像素分布示意图。
第二显示区240、过渡显示区232以及主显示区231设置有多个像素，例如，主显示区231设置有多个第一像素251，过渡显示区232设置有多个第二像素252，第二显示区240设置有多个第三像素253。
多个像素的排列方式可以为标准RGB排列，每个像素可以根据需要显示需要的颜色。例如，一个像素250可以包括R、G、B三种颜色的子像素，其可以根据需要显示红色、绿色、蓝色、白色、粉色、青色等各种颜色。
其中，可以通过改变多个像素单元的分布密度来改变相应显示区域的透光率，请参阅图6，为了满足主显示区对于显示质量的需求，主显示区231内的像素分布密度可以大于过渡显示区232以及第二显示区240的像素分布密度，例如，主显示区231的像素在相同面积区域260内排列有九个第一像素251，每一行三个第一像素，每一列三个第一像素。
请参阅图7，过渡显示区232的像素分布面密度可以小于主显示区231的像素分布密度，例如，过渡显示区232的像素在相同面积区域260内排列有两个第二像素252，第一行设置两个第二像素252，第一例设置一个第二像素252。在一些实施方式中，为了提高过渡显示区232和主显示区231之间显示画面的连贯性，可以通过改变过渡显示区232和主显示区231之间的边缘区域之间的像素分布密度实现，例如，边缘区域中属于过渡显示区232的第一部分的像素分布密度可以逐渐增大，第一部分越靠近主显示区231的像素分布密度越大，直到与主显示区231的像素分布密度相同，又例如，边缘区域中属于主显示区231的第二部分的像素分布密度可以逐渐减少，第二部分越靠近过渡显示区232的像素分布密度越小，直到与过渡显示区232的像素分布密度相同，又例如，边缘区域中属于过渡显示区232的第一部分的像素分布密度逐渐增大、属于主显示区231的像素分布密度逐渐减小，在第一部分和第二部分相连的位置具有相同的像素分布密度。具体的像素分布可以根据主显示区域231和过渡显示区232域的具体显示区域设置。
为了满足第二显示区与过渡显示区之间的衔接，第二显示区可以设置与过渡显示区相同的像素分布密度，但是为了提高第二显示区的透光率，第二显示区的像素分布密度可以小于过渡显示区的像素分布密度，请继续参阅图8，第二显示区的像素在相同面积区域260内排列有一个第三像素253，相似的，为了提升第二显示区240与过渡显示区232之间显示画面的连贯性，可以通过改变第二显示区240和过渡显示区232之间的边缘区域之间的像素分布密度实现，例如，边缘区域中属于第二显示区240的第三部分的像素分布密度可以逐渐增大，第三部分越靠近过渡显示区232的像素分布密度越大，直到与过渡显示区232的像素分布密度相同，又例如，边缘区域中属于过渡显示区232的第四部分的像素分布密度可以逐渐减少，第四部分越靠近第二显示区240的像素分布密度越小，直到与第二显示区240的像素分布密度相同，又例如，边缘区域中属于第二显示区240的第三部分的像素分布密度逐渐增大、属于过渡显示区232的像素分布密度逐渐减小，在第三部分和第四部分相连的位置具有相同的像素分布密度。具体的像素分布可以根据第二显示区240域和过渡显示区域232的具体显示区域设置。
示例性的，以主显示区231的的像素分布密度为400PPI（每英寸像素）为例，过渡显示区232的像素分布密度可以为200PPI或131PPI，第二显示区240的像素分布密度可以为131PPI，进而增大第二显示区240的透光率。需要说明的是，不同区域的像素密度分布具体数值仅仅是示例性，其他可以实现增大第二显示区240透光率的像素密度分布均属于本申请的保护范围。
为了更加全面的理解本申请实施例的显示面板。下面对实现面板如何根据摄像装置的信号控制显示面板的显示进行说明。
请结合图2、图3、图4以及图9，图9为本申请实施例提供的第二显示区和过渡显示区的驱动电路的结构示意图。
为了实现当摄像装置处于工作时，第二显示区240的透光率可以达到预设透光率，即摄像装置可以通过第二显示区240采集外界的光信号以成像，例如设置在第二驱动单元组2262给予第二显示区240的像素电极层242的像素电极高压信号时，使得像素电极和公共电极之间为高夹压，控制第二液晶层241的液晶偏转为第一预设角度，第二液晶层241的透光率可以达到预设透光率，即可以理解为液晶层为透光状态，第二驱动单元组2262给予第二显示区240的像素电极层242的像素电极低压信号时，控制第二液晶层241的液晶偏转第二预设角度，使得第二液晶层241的透光率小于预设透光率，即第二液晶层241为不透光状态，第二显示区240可以显示画面。
为了根据摄像装置的启动或关闭信号控制第二显示区240的显示，可以通过设置第一控制线271和第二控制线272来控制第二显示区240，其中第一控制线271和第二控制线272均与第二驱动单元组2262电性连接，第一控制线271和第二控制线272均与驱动芯片电性连接，第一控制线271用于传输电压信号，第二控制线272用于传输摄像装置的启动或关闭信号，驱动芯片可以根据摄像装置的启动或关闭状态向第二驱动单元组传输电压信号，以使第二显示区240的第二液晶层241偏转，在第一状态和第二状态转换，其中，第一状态为第二液晶层为透光状态，第二状态为第二液晶层为不透光状态。示例性地，当检测到摄像装置处于启动状态时，通过驱动芯片控制第二驱动单元组驱动第二液晶层的液晶偏转至第一预设角度，在第二液晶层的液晶处于第一预设角度时，第二显示区的透光率可达到95%，当检测到摄像装置处于关闭状态，且检测到显示画面的信号，通过驱动芯片控制第二驱动单元组驱动第二液晶层的液晶偏转至第二预设角度，在第二液晶层的液晶处于第二预设角度时，第二显示区处于显示预设画面的状态，当检测到摄像装置处于关闭状态，且未检测到显示画面的信号，通过驱动芯片控制第二驱动单元组驱动第二液晶层的液晶偏转至第三预设角度，在第二液晶层的液晶处于第三预设角度时，第二显示区不显示预设画面，且透光率小于预设透光率，即从外界看不到与第二显示区相对设置的摄像装置。
在一些实施方式中，像素电极层包括多个像素电极和多个控制电极，像素电极可用于控制RGB像素单元，控制电极可用于控制透明像素单元，第二驱动单元组中包括多个第二驱动单元，每个第二驱动单元可以为一个薄膜晶体管，每个薄膜晶体管连接一个控制电极，以使控制电极对应的第二液晶层处于第一状态或第二状态，其中第一状态为第二液晶层为透光状态，第二状态为第二液晶层为不透光状态，可以理解的是，每个像素电极连接有一个第二驱动单元，以使像素电极对应的第二液晶层处于第三状态，其中第三状态为第二液晶层显示预设画面的状态。
在一些实施方式中，可以将多个控制电极连接，如通过导线将多个控制电极连接，以形成第一控制电极组，第一控制电极组连接一个第二驱动单元，仅通过一个第二驱动单元即可控制像素电极层中的多个控制电极，减少第一显示区的布线压力。
在一些实施方式中，将控制多个控制电极的薄膜晶体管设置于非显示区，可以进一步减少第一显示区的布线压力，具体的，显示面板还包括非显示区，非显示区设置有第三驱动单元组，第三驱动单元组包括一个或多个第三驱动单元，第三驱动单元可以为一个薄膜晶体管，像素电极层包括多个控制电极，每个控制电极电连接以形成第二控制电极组，第二控制电极组连接一个第三驱动单元，为了提高控制效果，第二控制电极组也可以连接多个第三驱动单元，第三驱动单元组用于驱动第二控制电极组对应的第二液晶层处于第一状态或第二状态，其中第一状态为第二液晶层为透光状态，第二状态为第二液晶层为不透光状态，可以理解的是，每个像素电极连接有一个第二驱动单元，以使像素电极对应的第二液晶层处于第三状态，其中第三状态为第二液晶层显示预设画面的状态。
为了更加全面的理解本申请实施例的电子设备。下面对电子设备的结构作进一步说明。请参阅图10，图10为本申请实施例提供的电子设备的结构示意图，本申请实施例提供的电子设备可以是手机、平板电脑等移动终端设备，还可以是游戏设备、增强现实（Augmented Reality，AR）设备、虚拟现实（Virtual Reality，VR）设备、车载电脑、笔记本电脑、数据存储装置、音频播放装置、视频播放装置、可穿戴设备等具有显示面板的设备，其中可穿戴设备可以是智能手环、智能眼镜等。
