液晶显示装置(Liquid Crystal Display，LCD)具有机身薄、省电、无辐射等众多优点，得到了广泛的应用。随着液晶显示技术的飞速发展和人们对液晶显示器的品质要求的不断提高，人们对液晶显示器的显示区域占比的要求也越来越高，因此高屏占比、窄边框成为产品技术发展的重要方向。
 技术问题
为了实现更高的屏占比，在增加显示屏大小的同时，也减少了电子设备正面的功能组件的安装空间，现有技术中一般将这些功能组件设置在电子设备侧面或背面，亦或是采用隐藏式的设计将功能组件设置在屏下。而手机前置摄像头会占据一定的屏幕空间，导致屏幕屏占比降低。目前的一种解决方案为在手机屏幕上开孔，将前置摄像头放置在屏幕开孔的下方，或者屏幕不开孔，但是预留出一定的空白位置，通常空白位置不显示画面。在该空白位置下方放置摄像头。但这种设计方案在外观上还是会看到屏幕上有开孔的样子，无法达到真正的全面屏的视觉效果。
综上所述，现有液晶显示装置存在屏占比较低的问题。故，有必要提供一种显示面板及制作方法、显示装置来改善这一缺陷。

下面结合附图和具体实施例对本揭示做进一步的说明：
本揭示实施例提供一种显示面板，下面结合图1至图3进行详细说明。
如图1所示，图1为本揭示实施例所提供的显示面板100的示意图，其中左侧图示为显示面板100的侧面示意图，右侧图示为显示面板100的正面示意图。图2为本揭示实施例提供的显示面板100沿A-A方向的截面结构示意图。所述显示面板100包括第一基板110、第二基板120、液晶层130和摄像组件160，所述第一基板110和所述第二基板120相对设置，所述液晶层130设置于所述第一基板110和所述第二基板120之间，所述摄像组件设置于所述第二基板120远离所述第一基板110的一侧上。
如图2所示，所述第一基板110靠近所述第二基板120的一侧设有彩色滤光层140，所述彩色滤光层140与所述摄像组件160对应的位置上设有透光部分141，所述第二基板120靠近所述第一基板110的一侧设有薄膜晶体管层150。所述彩色滤光层140包括多个红色子像素、蓝色子像素、绿色子像素以及设置于相邻像素之间的黑矩阵。
具体地，所述透光部分141为贯穿所述彩色滤光层140的导孔，用于为所述摄像组件160提供光线传播的路径，显示面板外侧的入射光线可以先后通过第一基板110、透光部分141再经过液晶层130以及第二基板120最后到达摄像组件160，从而实现摄像组件160获取外界光线的条件。
在本实施例中，所述透光部分沿如图1所示的B-B方向的截面形状包括多边形、圆形或椭圆形。
在本实施例中，为了增加摄像组件160获取外界光线量，实现更好地拍照摄像效果，所述透光部分141沿B-B方向的截面面积应大于或等于所述摄像组件160沿B-B方向的截面面积。
在本实施例中，所述第二基板靠近所述第一基板一侧设有薄膜晶体管层150，所述薄膜晶体管层150用于：当接收所述摄像组件160启动指令后，控制所述液晶层130对应所述透光部分141的液晶偏转，使得光线通过所述液晶层130抵达所述摄像组件160；当接收所述摄像组件160关闭指令后，控制所述液晶层130对应所述透光部分141的所述液晶偏转，使得光线无法通过所述液晶层130，所述透光部分141对应的显示面板显示部分呈现黑色画面。
如图1所示，将显示面板的显示部分划分为第一显示部分101和第二显示部分102，所述第一显示部分101设置为显示面板的状态栏，所述第二显示部门102设置于常规显示部分。具体地，将所述第一显示部分101固定设置为黑色，即在摄像组件160关闭时，透光部分141呈现的黑色画面与第一显示部分101呈现的黑色画面融为一体，即可呈现全面屏显示的视觉效果。
具体地，所述薄膜晶体管层150包括层叠设置于所述第二基板上的缓冲层、栅极绝缘层、栅极线层、层间介质层、源漏电极层、平坦层和像素电极层（图中未示出）。
在本实施例中，如图3所示，所述显示面板100还包括公共电极层111，所述公共电极层111设置于所述彩色滤光层140靠近所述第二基板120的一侧上。所述公共电极层111覆盖所述彩色滤光层140并覆盖所述透光部分141。所述公共电极层111为透明电极，材质为氧化铟锡（Indium Tin Oixde, ITO），因此所述公共电极层111填充所述透光部分141，在实现与对应部分的薄膜晶体管共同控制液晶偏转的同时，能够保持光线从透光部分141通过进入摄像组件160。
在本实施例中，如图3所示，所述显示面板100还包括第一配向层112和第二配向层121，所述第一配向层112设置于所述公共电极层111靠近所述第二基板120的一侧上，所述第二配向层121设置于所述薄膜晶体管层150靠近所述第一基板110的一侧上。
在本实施例中，所述显示面板100还包括第一偏光片113和第二偏光片122，所述第一偏光片113设置于所述第一基板110远离所述第二基板120的一侧上，所述第二偏光片122设置于所述第二基板120和所述摄像组件160之间。
在本实施例中，第一基板110为彩膜基板，所述第二基板120为阵列基板。
本揭示实施例通过在彩色滤光层140上设置用于提供光线传播路径的透光部分141，并将摄像组件160设置于第二基板120远离第一基板110一侧与所述透光部分141对应的位置上，当接收所述摄像组件160启动指令后，薄膜晶体管层150控制所述液晶层130对应所述透光部分141的液晶偏转，使得光线通过所述液晶层130抵达所述摄像组件160，实现屏幕下摄像组件160获取外界光线的条件；当接收所述摄像组件160关闭指令后，控制所述液晶层130对应所述透光部分141的所述液晶偏转，使得光线无法通过所述液晶层130，所述透光部分141呈现黑色画面，从而使得显示面板100从外观上是一个整体，实现全屏显示的效果。
本揭示实施例还提供一种显示装置，包括如上述的显示面板100。且所述显示装置能够实现如上述显示面板100相同的技术效果，此处不再赘述。
本揭示实施例还提供一种显示面板的制作方法，下面结合图3和图4进行详细说明。
如图4所示，图4为本揭示实施例提供的显示面板的制作方法的流程示意图，所述方法包括：
步骤S10：提供第一基板110和第二基板120，在所述第一基板110靠近所述第二基板120一侧形成彩色滤光层140以及用于提供光线传播路径的透光部分141，所述透光部分141为贯穿所述彩色滤光层140的导孔；
步骤S20：在所述彩色滤光层140上靠近所述第二基板120的一侧上依次形成公共电极层111和第一配向层112；
步骤S30：将所述第一基板110和所述第二基板120成盒形成显示面板100；
步骤S40：在所述第二基板120远离所述第一基板110的一侧上与所述透光部分141对应的位置设置摄像组件160。
结合上述图3，所述第一基板110和所述第二基板120的具体制作工艺这里不再赘述，可以利用现有技术中的方式。所述步骤S10中，透光部分141可以在沉积红、绿、蓝等子像素时通过挡板对所述透光部分141进行遮盖，以此形成贯穿所述彩色滤光层140的透光部分141。在一些实施例中，也可以先沉积彩色滤光层140，再对所述彩色滤光层140进行刻蚀，从而形成贯穿所述彩色滤光层的透光部分141。
具体地，步骤S20中，可以采用物理气相沉积（Physical Vapor Deposition,PVD）或者化学气相沉积（Chemical Vapor Deposition, CVD）的方法形成所述公共电极层111。
所述公共电极层111为透明电极，材质为氧化铟锡（Indium Tin Oixde, ITO），因此所述公共电极层111填充所述透光部分141，在实现与对应部分的薄膜晶体管共同控制液晶偏转的同时，能够保持光线从透光部分141通过进入摄像组件160。
在本实施例中，所述第二基板靠近所述第一基板一侧设有薄膜晶体管层150，所述薄膜晶体管层150用于：当接收所述摄像组件160启动指令后，控制所述液晶层130对应所述透光部分141的液晶偏转，使得光线通过所述液晶层130抵达所述摄像组件160；当接收所述摄像组件160关闭指令后，控制所述液晶层130对应所述透光部分141的所述液晶偏转，使得光线无法通过所述液晶层130，所述透光部分141对应的显示面板显示部分呈现黑色画面。
本揭示实施例通过在彩色滤光层140上设置用于提供光线传播路径的透光部分141，并将摄像组件160设置于第二基板120远离第一基板110一侧与所述透光部分141对应的位置上，当接收所述摄像组件160启动指令后，薄膜晶体管层150控制所述液晶层130对应所述透光部分141的液晶偏转，使得光线通过所述液晶层130抵达所述摄像组件160，实现屏幕下摄像组件160获取外界光线的条件；当接收所述摄像组件160关闭指令后，控制所述液晶层130对应所述透光部分141的所述液晶偏转，使得光线无法通过所述液晶层130，所述透光部分141呈现黑色画面，从而使得显示面板100从外观上是一个整体，实现全屏显示的效果。
综上所述，虽然本揭示以优选实施例揭露如上，但上述优选实施例并非用以限制本揭示，本领域的普通技术人员，在不脱离本揭示的精神和范围内，均可作各种更动与润饰，因此本揭示的保护范围以权利要求界定的范围为基准。
