Description

一种显示面板及显示装置 技术领域
本申请涉及显示屏技术领域，具体涉及一种显示面板及显示装置。
发明背景
随着显示面板技术的不断发展，人们对于显示面板的要求也越来越高，特别是显示效果的要求，例如像素密度和显示区域的需求越来越高，为了提高显示区域的面积，常规设置摄像头的区域也被用于显示，这样既能提高屏占比，也能够提高美观。然而，摄像头区域用于显示就需要在该区域设置像素单元，而整齐排布的像素单元之间形成了细长的缝隙，容易产生光线的衍射现象，从而导致拍照或摄像时出现光斑。
发明内容
有鉴于此，本申请实施例致力于提供一种显示面板及显示装置，通过在显示区内设置至少两个图像采集区，并且在图像采集区内设置阵列排布的驱动电路和连接驱动电路的多条金属走线，以实现图像采集区内像素单元的驱动发光，从而实现图像采集区的显示功能，并且通过在每个图像采集区内设置一个图像采集部件，至少两个图像采集部件分别通过各自对应的图像采集区采集图像，并将采集得到的至少两个图像进行算法处理以消除衍射光斑，其中，至少两个图像中的衍射光斑各不相同；即利用至少两个图像采集部件通过不同的图像采集区采集得到的图像中的衍射光斑不同，利用算法将至少两个图像中相同位置的衍射光斑进行处理，从而消除图像中的衍射光斑，得到最终不带衍射光斑的图像，从而提高了显示效果。
根据本申请的一方面，本申请一实施例提供的一种显示面板，包括：显示区和所述显示区内的至少两个图像采集区；其中，每个所述图像采集区内包括多个阵列排布的驱动电路和连接所述驱动电路的多条金属走线，每个所述图像采集区内包括一个图像采集部件，至少两个所述图像采集部件分别通过对各自对应的所述图像采集区采集图像，并将采集得到的至少两个图像进行算法处理以消除衍射光斑；其中，所述至少两个图像中的衍射光斑各不相同。
根据本申请的另一方面，本申请一实施例提供的一种显示装置，包括如上述任一项所述的显示面板。
本申请提供的一种显示面板及显示装置，通过在显示区内设置至少两个图像 采集区，并且在图像采集区内设置阵列排布的驱动电路和连接驱动电路的多条金属走线，以实现图像采集区内的像素单元的驱动发光，从而实现了图像采集区的显示功能，并且通过在每个图像采集区内设置一个图像采集部件，至少两个图像采集部件分别通过各自对应的图像采集区采集图像，并将采集得到的至少两个图像进行算法处理以消除衍射光斑，其中，至少两个图像中的衍射光斑各不相同；即利用至少两个图像采集部件通过不同的图像采集区采集得到的图像中的衍射光斑不同，利用算法将至少两个图像中相同位置的衍射光斑进行处理，从而消除图像中的衍射光斑，得到最终不带衍射光斑的图像，从而提高了显示效果。
附图简要说明
图1所示为本申请一实施例提供的一种显示面板的结构示意图。
图2所示为本申请另一实施例提供的一种消除衍射光斑的原理图，其中，显示面板内的不同的图像采集区内的金属走线的延伸方向不同。
图3所示为图1中的显示面板的驱动电路与现有技术的显示面板的驱动电路的对比示意图。
实施本发明的方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。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前提下所获得的所有其他实施例，都属于本申请保护的范围。
为了提高显示面板的显示面积和屏占比，越来越多的显示面板已经开始尝试窄边框或全面屏，然而由于显示面板通常都具备摄像功能，特别是前置摄像功能，则需要显示面板显示侧的外部光线进入显示面板的图像采集部件(例如摄像头)，目前常见的是设置前置摄像头，这样就能够由前置摄像头采集外部光线，从而实现显示面板显示侧的图像采集。然而实现前置摄像头则需要在显示面板上预留一定的位置区域来放置前置摄像头，该位置区域是不能实现显示的，从而导致显示面板的屏占比不能进一步提高，不能实现全面屏。为了解决这个问题，屏底摄像头应运而生，即将摄像头设置于显示屏体的底部(显示面板的非显示侧)，在摄像头与显示面板的显示侧之间建立光线传播的路径，以实现前置摄像或拍照，同时在摄像区域设置像素单元以实现显示功能，从而提高显示面板的显示区域和屏占比。虽然这种方式可以实现摄像区域的图像采集和显示功能，但是由于像素单元之间形成了细长的缝隙，使得阵列排布的像素单元及其缝隙形成了衍射光栅，显示面板显示侧的光线进入该衍射光栅后发生衍射现象，从而导致采集的图像中出 现衍射光斑，例如夜晚拍摄点亮的路灯时，图像中路灯的灯源位置会出现一个亮点，并且在该亮点的周围会出现亮斑(可能是十字亮斑)。
衍射光斑的一个必要条件就是细长的缝隙，因此，有些显示面板采用将摄像区域的像素密度降低，从而加宽像素单元之间的缝隙宽度，以降低衍射光斑现象，然而降低像素密度就会降低摄像区域的显示效果，并且与其他显示区域的显示效果会存在明显区别，从而降低了显示面板的显示效果和用户体验效果。
出于解决衍射光斑和显示效果的矛盾，本申请提供了一种显示面板及显示装置，通过在显示区1内设置至少两个图像采集区2，并且在图像采集区2内设置阵列排布的驱动电路3和连接驱动电路的多条金属走线4，以实现图像采集区内的像素单元的驱动发光，从而实现了图像采集区2的显示功能，并且通过在每个图像采集区2内设置一个图像采集部件6，至少两个图像采集部件6分别通过各自对应的图像采集区2采集图像，并将采集得到的至少两个图像进行算法处理以消除衍射光斑，其中，至少两个图像中的衍射光斑各不相同；即利用至少两个图像采集部件6通过不同的图像采集区2采集得到的图像中的衍射光斑不同，利用算法将至少两个图像中相同位置的衍射光斑进行处理，从而消除图像中的衍射光斑，得到最终不带衍射光斑的图像，从而提高了显示效果。
至少两个图像采集部件可以将采集得到的至少两个图像中的衍射光斑进行叠加且只保留重叠部分。当至少两个图像采集部件分别采集到图像后，可以通过算法将采集到的至少两个图像中的衍射光斑进行叠加且只保留重叠部分，即将至少两个图像进行对位叠加，以实现至少两个图像中的同一位置的衍射光斑中心位置重合，然后将非重合位置的亮斑删除或设置为背景，从而实现了衍射光斑的消除。本申请实施例只是示例性的给出了一种算法实现衍射光斑消除的方法，本申请还可以采用其他的算法，只要所采用的算法可以实现衍射光斑消除即可，本申请对于消除衍射光斑的具体算法不做限定。
如图1所示，该显示面板包括：显示区1和显示区1内的两个图像采集区2；其中，每个图像采集区2内包括多个阵列排布的驱动电路3和连接驱动电路3的多条金属走线4，每个图像采集区2内包括一个图像采集部件6，两个图像采集部件分别通过对各自对应的图像采集区2采集图像，并将采集得到的两个图像进行算法处理以消除衍射光斑。通过在显示区1内的两个图像采集区2内正常设置像素单元、驱动像素单元发光的驱动电路以及连接驱动电路的多条金属走线，以实现该两个图像采集区2的正常显示功能，并且该两个图像采集区2内的像素单元的密度与显示区1的其他区域一致，该两个图像采集区2内的驱动电路的密度与显示区1的其他区域一致，从而保证了显示区1的显示一致性；为了解决该两个图像采集区2内的衍射光斑现象，本实施例在每个图像采集区2内设置一个图像采集部件6，并且该两个图像采集部件6分别通过对各自对应的图像采集区2进 行图像采集，即两个图像采集部件采集图像的光路不同，由于不同的光路所产生的衍射光斑有所区别(例如衍射光斑的中心点相同但延伸方向不同等)，因此可以将两个图像采集部件6所采集的图像进行算法处理，从而将处理后的图像中的衍射光斑消除，还原图像的本来面貌。
在本实施例中，图像采集部件可以为摄像头等采集图像的设备，在其他实施例中，可以根据实际应用场景的需求而选取图像采集部件的类型，只要所选取的图像采集部件的类型能够实现图像采集即可，本申请对于图像采集部件的具体类型不做限定。在本实施例中，图像采集部件的数量可以为两个。由于两个图像采集部件则可以得到两个衍射光斑不同的图像，即两个图像采集部件即可实现算法消除衍射光斑，当然，其他实施例也可以根据实际应用场景的需求而选取图像采集部件的数量，例如选取3个或更多的图像采集部件，以提高成像的效果，只要所选取的图像采集部件的数量能够满足消除衍射光斑的需求即可，本申请对于图像采集部件的具体数量不做限定。
在本实施例中，结合图1所示，金属走线4靠近待采集图像的一侧表面可以设置遮挡金属走线4的金属层5。通过在金属走线4上设置金属层5，可以利用金属层5将金属走线4遮挡，以尽量避免光线在金属走线4处发生衍射，从而可以降低衍射光斑的生成概率，即减少了衍射光斑的数量，从而更加有利于消除衍射光斑，同时也能避免衍射光斑过多而导致采集的图像中过多的信息被衍射光斑所掩盖，也就避免了消除衍射光斑后的图像失真，即提高了图像的真实性。
本申请中，金属层5可以是金属层M4(即数据信号线所在金属层)或者其他的金属层。可以通过金属走线4相邻的金属层5将金属走线4遮挡以避免产生衍射现象。本申请可以根据实际应用场景的需求而选取不同的金属层遮挡金属走线，只要所选取的金属层能够实现金属走线的遮挡即可，本申请对于金属层的具体膜层不做限定。
本申请中，遮挡不同的金属走线4的金属层5沿膜层层叠方向的厚度可以不同。通过将遮挡金属走线4的金属层5沿膜层层叠方向的厚度设置不同，可以从振幅或相位方面改变光线的光波方程，从而可以避免相互靠近的光线所产生的衍射光波进行叠加而形成衍射光斑，进一步消除衍射光斑。本申请可以根据实际应用场景的需求而选取金属层5的厚度，例如沿一个方向金属层5的厚度逐渐减小，只要所选取的金属层的厚度能够实现金属走线的遮挡且改变衍射光波的叠加即可，本申请对于金属层的具体厚度不做限定。
本申请中，金属走线4的形状可以包括曲线或直线。由于细长的缝隙是产生衍射光斑的一个必要条件，因此，可以将金属走线4设置为曲线，例如曲线函数形状线条，从而可以降低衍射光斑的产生概率。本申请可以根据实际应用场景的需求而选取金属走线的不同形状，只要所选取的金属走线的形状能够实现驱动电 路的电连接且降低衍射光斑的产生概率即可，本申请对于金属走线的具体形状不做限定。
结合图2所示，在其他实施例中，不同的图像采集区内的金属走线(图2中未示出)的延伸方向可以不同。以两个图像采集部件和两个图像采集区为例，两个图像采集部件分别采用图2中左右两个图像采集区，且该两个图像采集区中的驱动电路3的排布相同、金属走线的延伸方向不同，由于金属走线和遮挡金属走线的金属层5的延伸方向一致，图2中以金属层5的延伸方向表示金属层5所遮挡的金属走线的延伸方向，其中左侧的图像采集区中的金属层5(即对应的金属走线)为横纵方向设置，而右侧的图像采集区中的金属层5(即对应的金属走线)为倾斜设置(即与横纵方向呈现一定倾斜角度，例如45度)，从而实现了两个图像采集部件分别得到图2中对应的衍射光斑形状，然后将两个衍射光斑进行算法处理得到中间重叠的亮点，即实现了衍射光斑的消除，提高了图像采集效果。本申请可以根据实际应用场景的需求而选取金属走线的延伸方向，只要所选取的金属走线的延伸方向能够实现驱动电路的电连接且获取不同衍射光斑形状即可，本申请对于金属走线的具体延伸方向不做限定。
本申请中，金属走线4可以包括透明金属线，通过设置透明金属线，可以提高金属走线4的透光率，从而提高图像采集的效果。
本申请中，图像采集区2内的像素单元可以沿一个方向排布，也可以错位排布，本申请对此不做限定。本申请中的驱动电路3可以是传统的RGB像素单元的驱动电路，例如Vstye-4的驱动电路，具体的，可以是7T1C电路，本申请对此不做限定。
图3所示为本申请提供的显示面板的驱动电路3与现有技术的显示面板的驱动电路3'的对比示意图。如图3所示，驱动电路3的线宽可以小于或等于2微米、线距可以小于或等于1.8微米。具体的，驱动电路3可以通过对应的曝光机制备，其中，曝光机的线宽参数小于或等于2微米，从而使制备得到的驱动电路的线宽小于或等于2微米，曝光机的线距参数小于或等于1.8微米，从而使制备得到的驱动电路的线距小于或等于1.8微米。通过将驱动电路3的尺寸缩小，并放置在相应的阳极位置下方(不发光的一侧)，即，驱动电路3覆盖于显示面板的阳极的不发光的一侧，如图3中虚线部分为现有的驱动电路3'(通过线宽参数大于2微米、线距参数大于1.8微米的曝光机制备得到)，实线部分为本申请实施例中的驱动电路3，从而减少不透光面积，保证了光线的透过率，提高了图像采集的效果。本申请可以根据实际应用场景的需求而选取驱动电路的尺寸，只要所选取的取驱动电路的尺寸能够满足驱动需求且保证光线透过率即可，本申请对于驱动电路的具体尺寸不做限定。
根据本申请的另一方面，本申请提供了一种显示装置，包括如上述任一实施 例所述的显示面板。本申请实施例提供的显示装置，通过在显示区内设置至少两个图像采集区，并且在至少两个图像采集区内设置阵列排布的驱动电路和连接驱动电路的多条金属走线，以实现至少两个图像采集区内的像素单元的驱动发光，从而实现了至少两个图像采集区的显示功能，并且通过在每个图像采集区内设置一个图像采集部件，至少两个图像采集部件分别通过各自对应的图像采集区采集图像，并将采集得到的至少两个图像进行算法处理以消除衍射光斑，即利用至少两个图像采集部件通过不同的图像采集区采集得到的图像中的衍射光斑不同，利用算法将至少两个图像中相同位置的衍射光斑进行处理，从而消除图像中的衍射光斑，得到最终不带衍射光斑的图像，从而提高了显示效果。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内，所作的任何修改、等同替换等，均应包含在本申请的保护范围之内。
