请参照图1和图2，图1是本申请实施例提供的电子设备的立体示意图，图2是图1所示的电子设备沿A-A方向的截面示意图。本申请提供一种电子设备1000。具体地，该电子设备1000可以为移动或便携式并执行无线通信的各种类型的计算机系统设备中的任何一种(图1中只示例性的示出了一种形态)。具体地，电子设备1000可以为移动电话或智能电话(例如，基于iPhone T，基于Android T的电话)，便携式游戏设备(例如Nintendo DS T，PlayStation Portable T，Gaeboy Advance T，iPhone T)、膝上型电脑、PDA、便携式互联网设备、音乐播放器以及数据存储设备，其他手持设备以及诸如头戴式耳机等，电子设备1000还可以为其他的需要充电的可穿戴设备(例如，诸如电子手镯、电子项链、电子设备或智能手表的头戴式设备(HD))。
电子设备1000还可以是多个电子设备中的任何一个，多个电子设备包括但不限于蜂窝电话、智能电话、其他无线通信设备、个人数字助理、音频播放器、其他媒体播放器、音乐记录器、录像机、其他媒体记录器、收音机、医疗设备、车辆运输仪器、计算器、可编程遥控器、寻呼机、膝上型计算机、台式计算机、打印机、上网本电脑、个人数字助理(PDA)、便携式多媒体播放器(PP)、运动图像专家组(PEG-1或PEG-2)音频层3(P3)播放器，便携式医疗设备以及数码相机及其组合等设备。
在一些情况下，电子设备1000可以执行多种功能(例如，播放音乐，显示视频，存储图片以及接收和发送电话呼叫)。如果需要，电子设备1000可以是诸如蜂窝电话、媒体播放器、其他手持设备、腕表设备、吊坠设备、听筒设备或其他紧凑型便携式的设备。
需要说明的是，本申请中的术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示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”、“第三”的特征可以明示或者隐含地包括至少一个该特征。本申请的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
电子设备1000可以包括壳体结构600和显示屏500，壳体结构600和显示屏500连接并围设形成一容置空间601。该容置空间601可以用于设置摄像头机构、主板、电池等结构件，以使得电子设备能够实现相应的功能。其中，显示屏500、摄像头机构等结构件可以通过柔性电路板(Flexible Printed Circuit，FPC)分别与主板、电池等电性连接，以使得他们能够得到电池的电能供应，并能够在主板的控制下执行相应的指令。
壳体结构600可用于安装电子设备1000所需的各类电子器件，且壳体结构600可与显示屏500共同围设形成容置空间601。容置空间601可用于安装光学传感器等电子器件，以实现如指纹解锁、自动熄屏以及亮度自调节等功能。容置空间601还可用于安装如麦克风、扬声器、闪光灯、电路板以及电池的电子器件，以实现如语音交流、音频播放以及照明等功能。
显示屏500可以用于为电子设备1000提供图像显示功能，当用户使用电子设备1000的拍摄功能时，显示屏500可以呈现摄像头机构的成像画面，以供用户进行观察和操作。该显示屏500可以包括依次层叠设置的透明盖板300、触控面板200以及显示面板100。透明盖板300的表面可以具有平整光滑的特性，以便于用户进行点击、滑动、按压等触控操作。该透明盖板300的材质可以是玻璃等刚性材质，也可以是聚酰亚胺(Polyiide，PI)、无色聚酰亚胺(Cololess Polyiide，CPI)等柔性材质。触控面板200设置于透明盖板300和显示面板100之间，用于响应用户的触控操作，并将相应的触控操作转换为电信号传输至电子设备1000的处理器，使得电子设备1000能够对用户的触控操作做出相应的反应。显示面板100主要用于显示画面，并可以作为交互界面而指示用户在透明盖板300上进行上述触控操作。该显示面板100可以采用OLED(Organic Light-Eitting Diode，有机发光二极管)或者LCD(Liquid  Crystal Display，液晶显示器)以实现电子设备1000的图像显示功能。在本实施例中，透明盖板300、触控面板200以及显示面板100之间可以借助OCA(Optically Clear Adhesive，光学胶)、PSA(Pressure Sensitive Adhesive，压敏胶)等胶体贴合在一起。
请参照图3和图4，图3是相关技术中显示面板的结构示意图，图4是图3所示的显示面板的俯视示意图。相关技术中，像素结构800包括像素界定层801和像素单元802，像素界定层801位于衬底基板10上。其中，像素界定层801包括贯穿像素界定层201的像素孔8011，像素单元802收容于像素孔8011中并位于衬底基板10上。由于像素孔8011结构的限制，目前像素单元802发出的光线通常垂直于衬底基板10，使得像素单元802的出光区域面积大约等于像素单元802的面积。以钻石排布为例，像素单元802之间的间隙较大，使得显示面板100上间隙对应区域的亮度小于像素单元802对应区域的亮度，使得显示面板100的亮度一致性较差，影响用户体验。
请参照图5至图7，图5是图2所述的电子设备中显示面板一个实施例的截面示意图，图6是图5所示的显示面板的俯视示意图，图7是图5所示的显示面板又一个实施例的截面示意图。本申请实施例提供一种新的像素结构20，可包括但不限于像素界定层21和像素单元22。其中，像素界定层21包括贯穿像素界定层21的像素孔211，像素单元22收容于像素孔211中并位于衬底基板10上。其中，像素孔211的内表面2111平行于衬底基板10的开口截面面积自衬底基板10一端向另一端逐渐变大，以使像素单元22发出的光线经像素孔211的内表面2111反射后，其出光区域面积大于像素单元22的面积。可以理解地，每个像素单元22的出光区域面积大于其自身的面积，使得相邻像素单元22的出光区域之间的间隙远小于相邻像素单元22的间隙，进而使得显示面板100上的光线亮度一致性更好。
请参照图8和图9在一个实施例中，内表面2111上可具有反射膜2112，以增强内表面2111的发光性能(如图8所示)。具体地，反射膜2112可以使用特定厚度的铝或者银。在又一个实施例中，像素界定层 21的材料能够反射光线，用于使内表面2111具有良好反射性能(如图9所示)。
具体地，像素孔211的内表面2111与衬底基板10的表面所成夹角小于或者等于临界夹角，其中，临界夹角为像素单元22的中点发出的光线经内表面2111的预设位置Q反射后、其反射光线垂直于衬底基板10时，预设位置Q对应的内表面2111与衬底基板10表面所成夹角。
请参照图5可以理解地，当内表面2111与衬底基板10的表面所成夹角等于临界夹角时，则像素单元22发出的光线经内表面2111反射后，其反射光线大部分都垂直于衬底基板10。具体地，当像素单元22中心入射至预设位置Q的光线经预设位置Q反射后的反射光线能够垂直于衬底基板10，则平行于像素单元22中心和预设位置Q的连线或者与其路径相似的光线经内表面2111反射后的反射光线均能够垂直于衬底基板10，进而使得像素单元22的出光区域面积大致等于内表面2111平行于衬底基板10且过预设位置Q的开口截面面积，进而实现减小相邻像素单元22出光区域间隙的目的。
当内表面2111与衬底基板10的表面所成夹角大于临界夹角时，像素单元22发出的光线经内表面2111反射后，其反射光线大部分都朝向像素孔211的中心方向收敛，则像素单元22的出光区域小于或者等于像素单元22的面积。具体地，当像素单元22中心入射至预设位置Q的光线经预设位置Q反射后的反射光线能够向像素孔211的中心线L收敛，则平行于像素单元22中心和预设位置Q的连线或者与其路径相似的光线经内表面2111反射后的反射光线均能够向像素孔211的中心线L收敛，进而使得像素单元22的出光区域面积小于内表面2111平行于衬底基板10且过预设位置Q的开口截面面积。
请参照图7，当内表面2111与衬底基板10的表面所成夹角小于临界夹角时，像素单元22发出的光线经内表面2111反射后，其反射光线大部分以像素孔211的中心线L向外发散，则像素单元22的出光区域小于或者等于像素单元22的面积。具体地，当像素单元22中心入射至预设位置Q的光线经预设位置Q反射后的反射光线能够以像素孔211 的中心线L向外发散，则平行于像素单元22中心和预设位置Q的连线或者与其路径相似的光线经内表面2111反射后的反射光线均能够以像素孔211的中心线L向外发散，进而使得像素单元22的出光区域面积大于内表面2111平行于衬底基板10且过预设位置Q的开口截面面积，也即大于所述像素单元22的面积，进而实现减小相邻像素单元22出光区域间隙的目的。
具体地，预设位置Q可位于像素界定层21的三分之一厚度与三分之二厚度之间对应的表面上。其中，像素单元22的弧度小于预设位置Q在像素界定层21的高度。具体地，令像素界定层21的厚度为H，像素单元22的厚度为D，也即D＜H/3。其中像素单元22的厚度为D可忽略不计。
当预设位置Q位于像素界定层21的三分之一位置时，像素单元22的厚度小于像素界定层21的厚度的三分之一；当预设位置Q位于像素界定层21的三分之二位置时，像素单元22的厚度小于像素界定层21的厚度的三分之二，以使像素单元22发出的光线经预设位置Q发射的光线能够垂直于衬底基板10或者以像素孔211的中心线L向外发散。
请参照图10，图10是图5所示的显示面板再一个实施例的截面示意图。在一个具体实施例中，预设位置Q位于像素界定层21二分之一厚度对应的内表面2111上，假设像素单元22为圆形且其直径为R且像素单元22的边缘与内表面2111相接，令临界夹角为α，像素单元22中心和预设位置Q的连线与衬底基板10所成夹角为β，则：
(H/2)/[(tanα)*H/2+R]＝tanβ；
也即，β＝α-(π/2-α)＝2α-π/2；
换言之，tanβ＝cot2α。
令内表面2111与衬底基板10的表面所成夹角γ。可以理解地，在像素界定层21的厚度H不变的情况下，γ越小，内表面2111上的反射光线以像素孔211的中心线L向外发散且与其反射光线与像素孔211中心线L的夹角越大，也即像素单元22的出光区域越大，像素单元22之间的距离越小，显示面板100的亮度一致性越好。
再者，当γ≤α且在γ不变的情况下，像素界定层21的厚度H越大，则像素单元22的出光区域越大，像素单元22之间的距离越小，显示面板100的亮度一致性越好。
请参照图11至图13，图11是图5所示的显示面板还一个实施例的截面示意图，图12是图11所示的显示面板一个变形的截面示意图，图13是图11所示的显示面板又一个变形的截面示意图。可选地，内表面2111平行于衬底基板10的开口截面形状与像素单元22的形状相似，以使像素孔211能够收容像素单元22，且像素单元22入射至像素孔211的内表面2111光线强度相一致。
本实施例中，内表面2111平行于衬底基板10的截面形状呈矩形，对应地，像素单元22呈矩形。可以理解地，在当内表面2111与衬底基板10的表面所成夹角小于临界夹角的情况下，像素单元22的出光区域呈矩形且出光区域面积大于像素单元22面积。
在又一个实施例中，内表面2111平行于衬底基板10的截面形状呈圆形，对应地，像素单元22呈矩形。可以理解地，在当内表面2111与衬底基板10的表面所成夹角小于临界夹角的情况下，像素单元22的出光区域呈圆形且出光区域面积大于像素单元22面积。在其他实施例中，内表面2111平行于衬底基板10的截面形状还可以是三角形、正六边形等其他形状，在此不做具体限制。
以矩形像素单元22为例，内表面2111平行于衬底基板10的截面形状呈矩形。像素孔211的中心线L垂直于基板且与像素单元22的中点重合。
请参照图5或图7，在一个实施例中，内表面2111可包括第一线条2113，第一线条2113位于过像素孔211中心线L的平面上。第一线条2113为直线且第一线条2113与衬底基板10的表面成夹角小于或者等于临界夹角。可以理解地，当像素单元22中心入射至预设位置Q的光线经预设位置Q反射后的反射光线能够垂直于衬底基板10或者以像素孔211的中心线L向外发散，则平行于像素单元22中心和预设位置Q的连线或者与其路径相似的光线经内表面2111反射后的反射光线均能够 垂直于衬底基板10或者以像素孔211的中心线L向外发散，进而使得像素单元22的出光区域面积大于像素单元22的面积，进而实现减小相邻像素单元22出光区域间隙的目的。
换言之，像素界定层21可包括隔离条210，相邻的像素孔211之间通过隔离条210分隔并围成。隔离条210在相邻两像素孔211中心线L所在平面的截面可呈三角形或者梯形。以梯形截面的隔离条210为例(如图5所示)，梯形的两个腰分别对应于两个像素孔211的内表面2111。
请参照图11至图13，，在又一个实施例中，内表面2111可包括第二线条2114，第二线条2114位于像素孔211中心线L的平面上。第二线条2114包括弧形部2115，也即第二线条2114可以为弧线与直线的结合，也可以完全为弧线，在此不做具体限制。其中，弧形部2115上至少部分点的切线与衬底基板10的夹角小于临界夹角。可以理解地，当预设位置Q位于弧形部2115上且其切线与衬底基板10所成夹角等于临界角时，以预设位置Q为界限，弧形部2115部分能够使反射光线向中心轴方向收敛，另一部分以像素孔211的中心线L向外发散，其中以像素孔211的中心线L向外发散的出光区域面积大于像素单元22的面积，进而实现减小相邻像素单元22出光区域间隙的目的。
在一个具体的实施方式中，第二线条2114整体呈弧线状且内表面2111朝向衬底基板10一侧凹陷。当预设位置Q位于第二线条2114的中间位置时，第二线条2114上预设位置Q至衬底基板10上的切线与衬底基板10夹角小于临界夹角，也即该位置的反射光线能够以像素孔211的中心线L向外发散，其中以像素孔211的中心线L向外发散的出光区域面积大于像素单元22的面积，进而实现减小相邻像素单元22出光区域间隙的目的。而其他位置的切线与衬底基板10夹角大于临界夹角，其对应位置的反射光线能够向中心轴方向收敛。
请参照图12，在又一个具体实施方式中，第二线条2114整体呈弧线状且内表面2111向背离衬底基板10一侧凸起。当预设位置Q位于第二线条2114的中间位置时，第二线条2114上预设位置Q至衬底基板10上的切线与衬底基板10夹角大于临界夹角，其对应位置的反射光线能 够向中心轴方向收敛；而其他位置的切线与衬底基板10夹角小于临界夹角，其对应位置的反射光线能够以像素孔211的中心线L向外发散，其中以像素孔211的中心线L向外发散的出光区域面积大于像素单元22的面积，进而实现减小相邻像素单元22出光区域间隙的目的。
再一个实施例中，像素孔211可包括多个第一像素孔(图未示)、多个第二像素孔(图未示)和多个第三像素孔(图未示)，多个第一像素孔、多个第二像素孔与多个第三像素孔间隔设置。像素单元22可包括多个第一像素单元22a、多个第二像素单元22b和多个第三像素单元22c，其中第一像素单元22a对应并收容于第一像素孔中，第二像素单元22b对应并收容于第二像素孔中，第三像素对应并收容于第三像素孔中。以钻石排列的像素结构20为例，第一像素单元22a可为R(red，红)像素，第二像素单元22b可为B(blue，蓝)像素，第三像素单元22c可为G(green，绿)像素。
在又一个实施例中，在上一个实施例的基础上，像素孔211还可包括第四像素孔，像素单元22可包括第四像素单元，第四像素单元可对应并收容于第四像素孔中。具体地，像素结构20为RGBW排布，其中第四像素为W(white，白)像素。
本申请实施例提供的像素结构20，通过使像素孔211的内表面2111平行于衬底基板10的开口截面面积自衬底基板10一端向另一端逐渐变大，使得像素单元22发出的光线经像素孔211的内表面2111反射后，其出光区域面积大于像素单元22的面积，进而减小像素单元22之间的间隔，使得显示面板100的亮度一致性好。
以上所述仅为本申请的部分实施例，并非因此限制本申请的保护范围，凡是利用本申请说明书及附图内容所作的等效装置或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
