具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，下文将要描述的各种实施例将要参考相应的附图，这些附图构成了实施例的一部分，其中描述了实现本发明可能采用的各种实施例。应明白，还可使用其他的实施例，或者对本文列举的实施例进行结构和功能上的修改，而不会脱离本发明的范围和实质。
如图1所示，为本发明的一个较佳实施例提供一种带摄像功能的显示装置的显示模组1。包括依次排列的上基板组件11、液晶层12、下基板组件13、背光灯模组14、驱动电路模块15，其中，上基板组件11包括依次排列的上偏光片111、上玻璃基板112、滤光片113，下基板组件13包括依次排列的下玻璃基板131、TFT阵列132、下偏光片133，液晶层12填充于上基板组件11 与下基板组件13之间。
作为优选实施方式，显示模组1与现有技术的液晶显示器的工作原理类似，在各行列像素处通过电压控制TFT开关，从而控制液晶分子旋转程度，进而显示出各RGB子像素的显示程度，并据此生成图像。
摄像模组2整合于显示模组1内部，作为优选实施方式，摄像模组2可包括间隔地安装在显示模组1表面的多个子摄像模组，摄像模组2的各子摄像模组用于拍摄显示屏上方正对该子摄像模组处的图像，摄像模组2包括多个透镜单元21、与各透镜单元21相匹配的多个感光单元22、图像处理芯片组23，图像处理芯片组23用于处理并输出摄像模组2产生的图像。
作为优选实施方式的较佳实施例，图像处理芯片组23整合于驱动电路模块15内。图像处理芯片组23可包括用于识别成像的驱动芯片，具体地，可选CMOS-LCD驱动芯片。
图像处理芯片组23还包括用于图形叠加与后期处理的图像叠加处理芯片，具体地，可选用VGA控制芯片。通过该芯片的处理，默认情况下可得到一幅所有感光单元22所拍摄得到的图像叠加之后所形成一幅完整的图像，该图像的等效拍摄角度为正对显示屏前方，因此相当于位于显示屏正中央的摄像机垂直以垂直显示屏的角度拍摄得到的图像，由于成像的感光单元22包括多个感光像素，因此处理后形成的图像相较于传统的单摄像头拍摄的图像，其显示效果更逼真全面，优于单个摄像头所拍得的图像。
作为另一优选实施方式，还可通过选取某些特定部位的感光单元22所拍摄得到的图像进行叠加，并形成一幅完整的图像，通过选取不同部位的感光单元22可得到位于不同位置的感光像素所拍摄的图像，叠加后可形成不同拍摄点位与拍摄角度的图像。
请参考图2，2-1为如图1所示的滤光片113的结构示意图，图2-2为与滤光片113相对应的上玻璃基板112与透镜单元21的结构示意图。其中，滤光片113与上玻璃基板112的对应位置相互匹配，上玻璃基板112的透镜单元21位于与滤光片113的感光单元22相对应的位置处。
图2-1中，滤光片113包括像素区1131、感光单元22。
作为较佳实施例，滤光片113包括像素区1131与感光单元22，感光单元 22固定在滤光片113上，并间隔地布设在像素区1131中，像素区1131用于形成像素，由RGB阵列组成。作为优选实施方式，感光单元22离散间隔地布设于像素区1131中，感光单元22的分布方式可根据需要进行设计，考虑到感光单元22成像的需要，可设计为：感光单元22均匀分布于整个滤光片113的表面，这样可取得更好的成像效果。
图2-2中，透镜单元21位于上玻璃基板112上与滤光片113的感光单元22相对应的位置处，考虑到当感光单元22均匀分布于整个滤光片113的表面时，透镜单元21也相应地均匀分布于整个玻璃基板112上的表面上，这种设计相当于将多个微型摄像头离散设置在显示屏的表面，可保证从多个角度拍摄到显示屏正前方的图像，进而供后续的图像处理芯片组23处理以获得高质量的合成图像。当使用者采用该摄像显示屏进行视频聊天时，在直视屏幕正中央的情况下即可获得正对使用者瞳孔的视频图像。
请参考图3，为如图2所示的像素区1131和感光单元22的结构示意图，像素区1131只包括RGB阵列，感光单元22则包括RGB阵列和感光点221，感光点与RGB阵列交替排列。作为较佳实施例，RGB阵列与现有技术的液晶显示器中的RGB阵列类似，而感光点可由覆盖在该位置处的光敏材料薄层组成，作为优选实施方式，该材料可选用卤化银颗粒等银盐感光物质。
请参考图4，为如图1所示的摄像显示屏的摄像显示方法的流程图。
步骤S1，提供如图1所示的显示装置，并在该显示装置中开启摄像功能；
步骤S2，显示装置的显示屏前的物体发出的光线透过上偏光片111，进入各透镜单元21，通过透镜单元21聚焦后，进入各感光单元22生成图像，最后将各感光单元22生成的图像输入图像处理芯片组23；
步骤S3，使用图像处理芯片组23对各感光单元22生成的多个图像进行识别成像，以及进行叠加处理，得到一张完整的合成图片；
步骤S4，使用图像处理芯片组23对该合成图片进行平滑过渡处理；
步骤S5，使用如图1所示的显示装置的显示模组1将处理后的合成图片输出显示，即可在显示屏中得到显示屏正前方的视频图像。作为优选实施方式，在进行图像输出显示时，预先判断显示装置是否正在显示其他图像，若摄像时，显示装置未显示其他图像，则所述显示模组将处理后的合成图片输出到所述显 示装置的屏幕中央进行显示；
若摄像时，显示装置正在显示其他图像，则将其他图像的显示窗口缩小并置于所述显示装置的屏幕的一角，之后，所述显示模组将处理后的合成图片输出到所述显示装置的屏幕中央进行显示。
现有技术的带摄像功能的显示器，一般设有一个前置摄像头，该前置摄像头一般位于显示器的最上部，用户在使用这种带有前置摄像头的显示器进行自拍时，若要取得良好的自拍效果，需要直视前置摄像头，在这种情况下，用户无法同时审视屏幕观察自拍的效果，若用户从前置摄像头转移目光并直视屏幕，则又无法取得良好的自拍效果。
本发明较佳实施例的带摄像功能的显示屏，将多个微型感光成像单元离散设置在显示屏的表面，可保证从多个角度拍摄到显示屏正前方的图像，进而通过后续处理获取高质量的合成图像。当使用者采用该摄像显示屏进行视频聊天时，在直视屏幕正中央的情况下即可获得正对使用者瞳孔的视频图像，解决了现有技术的以上问题。
以上所述仅为本发明的较佳实施例而已，本领域技术人员知悉，在不脱离本发明的精神和范围的情况下，可以对这些特征和实施例进行各种改变或等同替换。另外，在本发明的教导下，可以对这些特征和实施例进行修改以适应具体的情况及材料而不会脱离本发明的精神和范围。因此，本发明不受此处所公开的具体实施例的限制，所有落入本申请的权利要求范围内的实施例都属于本发明的保护范围。
