Description
本发明涉及显示技术领域，尤其涉及一种全屏显示面板。
在平板显示技术中，有机发光二极管（Organic Light-Emitting Diode，OLED）显示器具有轻薄、主动发光、响应速度快、可视角大、色域宽、亮度高、功耗低及可制备柔性屏等诸多优异特性，引起了科研界和产业界极大的兴趣，逐渐成为继液晶显示器(Liquid crystal displays，LCD)后的第三代显示技术。
消费者对全面屏的要求，以手机为例，如果手机整体尺寸较大而实际可现实区域较小时，就像人从大房子搬家到小房子时，会产生闷堵的心理，所以消费者只会追求屏幕更大、屏占比更高的手机。而OLED显示器以其柔性的特征对于屏幕全屏化显示起到了至关重要的作用。
随着显示技术的发展，显示装置的显示效果越来越好，给人们带来了良好的视觉体验，但由于生活水平的提高，人们对显示装置的要求不仅局限于显示效果，还要求显示其具有多样化的功能，特别是AR（Augmented Reality，增强现实技术）及VR（Virtual Reality，虚拟现实技术）功能的实现等等。
为实现全面屏的多功能效果，需要将诸多传感器（sensor）以及摄像头（Camera）等放置于屏幕下方或者集成于屏幕内，集成感应器（Integrated sensor）可包含指纹识别传感器（fingerprint sensor）、距离传感器（Proximity sensor）、环境光感应传感器（Ambient light sensor）及人脸识别传感器等各种功能传感器，因此为了实现显示面板的多功能化，需要设置较多外部补偿电路，进而需要设置更多的边缘区域进行外部电路及芯片（IC）的布置，而现有的将芯片仅绑定在显示面板（Panel）下部区域的COP（Chip On Panel）方式已不足不能满足需求。
本发明的目的在于提供一种全屏显示面板，能够提供足够的边缘区域来进行外部补偿电路及驱动芯片的设置，进而有利于全屏显示面板多功能化的实现。
为实现上述目的，本发明提供一种全屏显示面板，包括显示主体部及至少两个分别设置在显示主体部不同侧的COP电路部；
所述显示主体部和COP电路部设置在同一柔性基板上，所述COP电路部从所述显示主体部的边缘向后弯折而贴附于显示主体部的背面。
所述COP电路部为两个，分别为设置于所述显示主体部下侧的第一COP电路部及设置于显示主体部左侧或右侧的第二COP电路部。
所述第一COP电路部和第二COP电路部在显示主体部的背面不重叠。
所述显示主体部包括设置在所述柔性基板上的TFT阵列层及设置在TFT阵列层上的OLED显示层。
所述全屏显示面板还包括分别设置在显示主体部背面或显示主体部内部的多个功能器件；
所述多个功能器件包括摄像头和多个传感器。
可选地，所述全屏显示面板还包括在所述显示主体部背面与所述COP电路部绑定连接的柔性电路板；
所述功能器件设置在柔性电路板上，从而通过柔性电路板设置在所述显示主体部背面。
所述功能器件通过容纳于所述显示主体部内部开设的孔洞中而设置在所述显示主体部内部。
所述显示主体部上对应于所述多个功能器件的区域为功能区；
所述COP电路部上设有驱动芯片及对所述功能区进行局部亮度补偿的外部补偿电路。
所述多个传感器包括指纹识别传感器、距离传感器、环境光传感器及人脸识别传感器。
所述柔性基板为聚酰亚胺基板。
本发明的有益效果：本发明提供的一种全屏显示面板，包括显示主体部及至少两个分别设置在显示主体部不同侧的可弯折的COP电路部，所述显示主体部和COP电路部设置在同一柔性基板上，所述COP电路部从所述显示主体部的边缘向后弯折而贴附于显示主体部的背面，通过在显示主体部不同侧分别设置COP电路部，从而提供了足够的边缘区域进行外部补偿电路及驱动芯片的设置，进而有利于全屏显示面板多功能化的实现。
