如图1所示，本发明实施例中提供了一种显示面板1，所述显示面板1包括显示区10，所述显示区10包括一透明显示区11和一非透明显示区12，所述非透明显示区12围绕所述透明显示区11。
如图2所示，在所述显示区10内，所述显示面板1还包括一背光板100和一液晶面板300。
所述液晶面板300设于所述背光板100上，其包括一液晶层310、一驱动层320以及一第一光源360。
所述液晶层310具有第一液晶区311以及第二液晶区312。
所述第一液晶区311内填充的为散射型液晶，并且其与所述透明显示区11相互对应。所述散射型液晶可以通过电场、电压、电流、频率等外在条件的改变从而使其液晶分子产生紊乱运动，促使所述第一液晶区311内液晶分子的排序、角度发生改变，是的其液晶分子的折射率产生变化，从而使入射到所述第一液晶区311内的入射光发生散射。所述第一液晶区311通过所述散射型液晶在所述透明显示区11内实现画面的显示，并且在摄像头2等屏下部件工作时，所述透明显示区11呈现透明状态，所述散射型液晶并不会阻碍所述摄像头2等屏下部件的采光。
所述第二液晶区312内填充的为常规型液晶，其与所述非透明显示区12相互对应。所述常规型液晶可以通过电场或电压的改变从而使其液晶分子产生运动，使得所述第二液晶区312内的液晶分子的排序发生改变，从而控制入射到所述第二液晶区312内的入射光的透过与否。所述第二液晶区312通过所述常规型液晶在所述非透明显示区12内实现画面的显示。
如图3所示，所述第一光源360设于所述液晶面板300靠近所述第一液晶区311的一侧，其为有机电致发光二极管（Organic Light-Emitting Diode，OLED）光源。由于所述有机电致发光二极管具有全彩化发光等特性，故用于为所述第一液晶区311提供彩色光源。
所述驱动层320设于所述液晶层310下方，其包括第一驱动电路321、第二驱动电路322以及第三驱动电路323。
所述第一驱动电路321对应于所述第一液晶区311，其可以为场时序驱动电路（Fringe-Field Switching，FFS）、共面转换驱动电路（In-Plain Switching，IPS）、垂直排列液晶（Vertical Alignment Liquid Crystal，VA）驱动电路、扭曲向列液晶（Twisted Nematic Liquid Crystal，TN）驱动电路等液晶显示驱动电路中的一种。所述第一驱动电路321用于为所述第一液晶区311提供驱动信号，根据需求驱动所述第一液晶区311内填充的散射型液晶，改变其液晶分子排序、角度以及透光率和折射率，从而实现所述透明显示区11的画面显示和透明的转换。
所述第二驱动电路322对应于所述第二液晶区312，其可以为薄膜晶体管（Thin Film Transistor，TFT）型驱动电路，也可以为其他驱动电路。所述第二驱动电路322用于为所述第二液晶区312提供驱动信号，驱动所述第二液晶区312内填充的常规型液晶，改变其液晶分子的排序，控制所述非透明显示区12的画面显示。
所述第三驱动层323对应于所述第一光源360，其为场时序驱动电路，用于为所述第一光源360提供驱动信号，控制所述有机发光二极管的发光。
在本实施例中，所述液晶面板300除去了现有技术中偏光片的结构，并且所述第一驱动电路321具有高开口率，所以光线可以轻松穿过所述第一驱动电路321，进入下一层结构中。
如图3所示，所述液晶面板300还包括一第一基板330、一第二基板340以及一框胶层350。所述第一基板330设于所述驱动层320远离所述液晶层310的一面上。所述第二基板340设于所述液晶层310远离所述驱动层320的一面上。所述框胶层350设于所述第一基板330和所述第二基板340的边缘，并与所述第一基板330和所述第二基板340围成一密封腔室，所述液晶层310、所述驱动层320以及所述第一光源360位于所述腔室内，所述框胶层350与所述液晶层310之间具有一缝隙，所述第一光源360设于所述缝隙内。所述腔室将所述液晶面板300中的各器件保护于一密闭空间内，并与外界的水氧隔绝，防止水氧对各显示器件的腐蚀侵害，延长所述液晶面板300的的使用寿命。
在所述透明显示区11的所述液晶面板300内，所述第一光源360通过所述第三驱动电路323将彩色光源射入所述第一液晶区311的所述散射型液晶中，通过所述第一基板330和所述第二基板340的反射到达液晶内部。当需要画面显示时，所述第一驱动电路321通过控制所述散射型液晶的旋转实现彩色光光线的散射，从而垂直从所述第一基板330射出显示画面。当需要透明时，则通过所述第一驱动电路321的控制使所述散射型液晶呈现透明状态，以获得采光通道。
所述背光板100具有一第一通孔101，所述第一通孔101对应于所述透明显示区11，所述第一通孔101为摄像头2等屏下部件提供采光通道。所述背光板100有多层光学膜片组成，例如反射片、导光板、扩散片、增光片等光学膜片中一种或多种。所述背光板100通过其多层的光学膜片的合作，在不增加光源数量的情况下，通过改善光线的角分布，引导光的散射方向，均匀光线，将光线集中到正视角度上，从而减少光源的损耗，提高所述显示面板1的轴向亮度。
如图2所示，在所述背光板100靠近所述第二液晶区312的一侧上设有一第二光源500，所述第二光源500为发光二极管（Light Emitting Diode，LED）光源，其通过所述背光板100为所述第二液晶区312提供光源。在液晶显示装置1000（Liquid Crystal Display，LCD）中，所述液晶面板300为被动发光原件，其本身并不发光，而是由其下方的背光模组照亮的，故所述第二光源500和所述背光板100组成所述背光模组，为所述第二液晶区312提供光源。
如图2所示，所述显示面板1还包括一第一偏光片200和一第二偏光片400。所述第一偏光片200所述背光板100和所述液晶面板300之间，其具有一第二通孔201，所述第二通孔201对应于所述透明显示区11。所述第二偏光片400设于所述液晶面板300远离所述第一偏光片200的一面上，其具有一第三通孔401，所述第三通孔401对应于所述透明显示区11。所述第二通孔201和所述第三通孔401为所述摄像头2等屏下部件提供采光通道。偏光片（Polarizer，POL）全称为偏振光片，用于控制特定光束的偏振方向，自然光在通过偏光片时，振动方向与偏光片透过轴垂直的光将被吸收，透过光只剩下振动方向与偏光片透过轴平行的偏振光。所述显示面板1中，所述第一偏光片200和所述第二偏光片400分别贴在所述液晶面板300的两侧，所述第一偏光片200用于将所述背光板100和所述第二光源500产生的光束转换为偏振光，所述第二偏光片400用于解析经液晶电调制后的偏振光，产生明暗对比，从而产生显示画面。
本发明实施例中还提供一种显示装置1000，其为液晶显示装置，并包括以上所述的显示面板1，以及一摄像头2，所述摄像头2设于所述显示面板1靠近所述背光板100的一面上，且与所述透明显示区11相互对应。所述摄像头2的大小可根据所述透明显示区11的大小进行调整，进一步优化所述摄像头2占用空间。所述显示装置1000具有全面屏显示效果，其可以为手机、平板电脑、笔记本电脑等任何具有显示功能的产品或者部件。
本发明实施例中提供一种显示面板1及显示装置1000。所述显示面板1将其显示区10分为透明显示区11和非透明显示区12。所述非透明显示区12为常规显示区，使用常规型液晶显示技术。所述透明显示区11使用的显示技术为散射型液晶显示技术。当所述摄像头2开启时，所述透明显示区11为透明状态，可以为所述摄像头2提供采光通道。当所述摄像头2关闭时，所述透明显示区11可以正常显示画面。本发明实施例中的显示面板1及显示装置1000通过结合两种液晶显示技术，使用散射型液晶显示技术实现与所述摄像头2所对应的透明显示区11的显示和透光双功能，消除了所述摄像头2对所述显示面板1的影响，从而促使所述显示面板1的屏占比能够达到100%，实现真正的全面屏显示，提高所述显示装置1000的美观度，提升用户的使用感受。
在本实施例中，所述透明显示区11在图1中为“U”形，但是在本发明的其他实施例中，所述透明显示区11还可以为圆形、椭圆形、方形、水滴形等其他形状，其层状结构与本实施例中的所述显示面板1及显示装置1000相似，因此不在此做过多赘述。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其它实施例，都属于本申请保护的范围。
虽然在本文中参照了特定的实施方式来描述本发明，但是应该理解的是，这些实施例仅仅是本发明的原理和应用的示例。因此应该理解的是，可以对示例性的实施例进行许多修改，并且可以设计出其他的布置，只要不偏离所附权利要求所限定的本发明的精神和范围。应该理解的是，可以通过不同于原始权利要求所描述的方式来结合不同的从属权利要求和本文中所述的特征。还可以理解的是，结合单独实施例所描述的特征可以使用在其他所述实施例中。
