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。
请参阅图1，其为本申请实施例显示面板的平面示意图。显示面板100具有一显示区100a以及显示透光区100b。显示区100a用于显示图像，显示透光区100b用于显示图像的同时，也用于透过外界射入至显示面板100的光线。显示区100a的面积大于显示透光区100b的面积。显示透光区100b可以位于显示面板100的一端的中间位置，也可以靠近显示面板100外围边缘或转角的位置，显示透光区100b也可以位于显示面板100的中间位置。显示透光区100b的形状可以为圆形以及矩形，也可以为U型。显示透光区100b设置有至少一第一显示像素单元，第一显示像素单元包括至少一微型发光二极管。
微型发光二极管（Micro Light Emitting Diode）的发光材料为无机材料。微型发光二极管具有尺寸小、发光效率高以及寿命长的优点，在显示透光区100b使用微型发光二极管作为显示像素单元可以使得透光显示区100b具有高透光率的同时，显示透光区100b的显示亮度高，且显示透光区100b的显示亮度不会随着显示面板使用时间的延长而出现明显的衰减，避免显示面板出现显示不良的问题。微型发光二极管的尺寸为5微米-50微米。一般而言，微型发光二极管由阴极、阳极以及位于阴极和阳极之间的无机半导体层形成。微型发光二极管的发光颜色与半导体禁带宽度相关，蓝光微型发光二极管采用禁带宽度较宽的半导体，红光微型发光二极管采用禁带宽度较窄的半导体。
本申请实施例显示面板通过在显示透光区设置微型有机发光二极管以进行显示，使得显示透光区具有高透光率以及高显示亮度的同时，避免显示面板出现显示不良的问题。
请参阅图2A和图2B，图2A为图1所示显示面板的显示区的一种局部放大示意图，图2B为图1所示显示面板的显示透光区的一种局部放大示意图。显示区100a设置有阵列排布的多个第二显示像素单元P2，第二显示像素单元P2包括有机发光二极管。显示透光区100b设置有多个第一显示像素单元P1。
相对于显示区和透光显示区全部设置微型发光二极管以作为显示单元，本实施例显示面板采用显示区100a设置有机发光二极管，而显示透光区100b设置微型发光二极管，能避免出现显示面板制造过程中微型发光二极管的转移良率低造成微型发光二极管易受损，导致显示面板显示异常的问题。相对于显示区和显示透光区全部设置有机发光二极管以作为显示单元，本实施例显示面板能保证显示透光区100b的显示亮度高的同时，避免显示面板出现显示问题。
在显示透光区100b，第一显示像素单元P1所占用的空间为显示透光区100b的显示区100c，任意两个相邻第一显示像素单元P1之间的间隙为显示透光区100b的透光区100d。为了使显示面板100的显示透光区100b的显示效果和透光效果达到均衡，第一显示像素单元P1在显示透光区100b占用的面积与显示透光区100b的面积的比值的取值范围为2/5-3/5。
显示区100a中第二显示像素单元P2的密度大于显示透光区100b中第一显示像素单元P1的密度，提高显示区的显示效果的同时，提高显示透光区100b的显示和透光效果。第一显示像素单元P1的尺寸小于等于第二显示像素单元P2的尺寸。任意两个相邻的第一显示像素单元P1之间的间距大于任意两个相邻的第二显示像素单元P2之间的间距。具体地，任意两个相邻的第一显示像素单元P1之间的间距为任意两个相邻的第二显示像素单元P2的间距的2-7倍。例如，任意两个相邻的第一显示像素单元P1之间的间距为50微米-100微米，任意两个相邻的第二显示像素单元P2之间的间距为15微米-25微米。需要说明的是，显示区100a中第二显示像素单元P2之间的间隙较小无法透光。
为了使显示区100a和显示透光区100b的显示画面具有均一性，每个第一显示像素单元P1由一红光微型发光二极管R1、一蓝光微型发光二极管B1以及一绿光微型发光二极管G1组成，每个第二显示像素单元P2由一红光有机发光二极管R2、蓝光有机发光二极管B2以及一绿光有机发光二极管组成G2。可以理解的是，每个第一显示像素单元P1还可以包括白光微型发光二极管，每个第二显示像素单元P2还可以包括白光有机发光二极管。第一显示像素单元P1和第二显示像素单元P2均采用标准RGB排列方式。
可以理解的是，每个第一显示像素单元P1采用标准RGB排列方式的同时，第二显示像素单元P2可以采用RGB Pentile排列方式，以适应显示区100a中第二显示像素单元P2的密度大而显示透光区100b中第一显示像素单元P1的密度小，即保证显示区100a和显示透光区100b的显示效果的同时，更好地利用显示区100a和显示透光区100b的空间。
具体地，如图3所示，图3为图1所示显示面板的显示区的另一种局部放大示意图。部分第二显示像素单元P2由红光有机发光二极管R2以及绿光有机发光二极管G2组成，其余部分第二显示像素单元P2由蓝色有机发光二极管B2以及绿色有机发光二极管G2组成。第一显示像素单元P1由红光微型发光二极管管R1、蓝光微型发光二极管B1以及绿光微型发光二极管G1组成。
请参阅图4，其为沿图1所示显示面板的A-A切线的截面示意图。显示面板100还包括封装层11，封装层11形成于显示区100a的第二显示像素单元P2上以封装第二显示像素单元P2，从而避免显示区100a的第二显示像素单元P2中的有机发光层与环境中的水以及氧气接触而导致显示面板100显示异常的问题。封装层11不形成于显示透光区100b以保证显示透光区100b的透光率。
显示面板100还包括薄膜晶体管阵列基板12，薄膜晶体管阵列基板12的显示透光区100b设置有第一薄膜晶体管T1，薄膜晶体管阵列基板12的显示区100设置有第二薄膜晶体管T2。第一显示像素单元P1设置于薄膜晶体管阵列基板12上且对应第一薄膜晶体管T1设置，第二显示像素单元P2设置于薄膜晶体管阵列基板12上且对应第二薄膜晶体管T2设置。第一薄膜晶体管T1与微型发光二极对应设置且电性连接，第二薄膜晶体管T2与有机发光二极管对应设置且电性连接。具体地，第一薄膜晶体管T1与微型发光二极管一一对应设置且电性连接，第二薄膜晶体管T2与有机发光二极管一一对应设置且电性连接。第一薄膜晶体管T1用于控制组成第一显示像素单元P1的子像素的工作状态，第二薄膜晶体管T2用于控制组成第二显示像素单元P2的子像素的工作状态。
微型发光二极管和有机发光二极管的亮度不同时，为了避免显示区100a和显示透光区100b之间的亮度平滑过渡，显示透光区100b包括第一显示透光区(未示出)和第二显示透光区（未示出），第一显示透光区位于显示区100a和第二显示透光区之间，第一显示透光区作为显示亮度渐变区，第一显示透光区的第一薄膜晶体管T1对应的数据电压从靠近显示区100a至靠近第二显示透光区逐渐变化，第一显示透光区的亮度等于第二显示透光区靠近第一显示透光区的亮度。第二显示透光区为圆形时，第一显示透光区为环形。例如，微型发光二极管的亮度大于有机发光二极管的亮度时，使得第二显示透光区的第一薄膜晶体管对应的数据电压从靠近显示区100a至靠近第二显示透光区的方向逐渐增大；微型发光二极管的亮度小于有机发光二极管的亮度时，使得第一显示透光区的第一薄膜晶体管T1对应的数据电压从靠近显示区100a至靠近第二显示透光区的方向逐渐减小，以避免观察到显示区和显示透光区之间的边界。
可以理解的是，也可以通过调整第一薄膜晶体管T1和第二薄膜晶体管T2的数据电压，以使得第一显示像素单元P1和第二显示像素单元P2的显示亮度基本相同，以提高显示面板显示效果的均一性。
请参阅图5，其为本申请实施例电子设备的结构示意图。电子设备可以为智能移动终端、平板电脑等。电子设备包括上述显示面板100、前置摄像头200以及主板300，主板300与前置摄像头200以及显示面板100均电性连接，前置摄像头200位于显示面板100的一侧且对应显示透光区100b设置，主板300位于前置摄像头200远离显示面板100的一侧。
本申请实施例电子设备通过在显示透光区设置微型有机发光二极管以使得显示透光区具有高透光率以及高显示亮度的同时，保证外界的环境光能穿过显示透光区的透光区部分并入射至前置摄像头，并避免电子设备出现显示不良的问题。
以上实施例的说明只是用于帮助理解本申请的技术方案及其核心思想；本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例的技术方案的范围。
