Description

显示面板和显示装置 技术领域
本申请涉及显示面板技术领域，尤其涉及一种显示面板和显示装置。
 背景技术
与LCD（Liquid Crystal Display，液晶显示器）相比，AMOLED（Active-matrix organic light-emitting diode，有源矩阵有机发光二极体或主动矩阵有机发光二极体）具有高对比度、超轻薄、可弯曲等诸多优点。但是，由于晶化工艺的局限性，在大面积玻璃基板上制作的LTPS（Low Temperature Poly-silicon，低温多晶硅技术）TFT（Thin Film Transistor，薄膜晶体管），不同位置的TFT常常在诸如阈值电压和迁移率等电学参数上具有非均匀性，这种非均匀性会转化为OLED显示器件的电流差异和亮度差异，并被人眼所感知，即Mura（显示不均）现象。另外，Oxide TFT（氧化物薄膜晶体管）虽然工艺的均匀性较好，但是与a-Si TFT（非晶硅薄膜晶体管）类似，在长时间加压和高温下，其阈值电压会出现漂移，由于显示画面不同，面板各部分TFT的阈值漂移量不同，会造成显示亮度差异，由于这种差异与之前显示的图像有关，因此常呈现为残影现象，也就是通常所说的残像。
因此，在当前的工艺制作中，不管是LTPS TFT技术还是Oxide TFT技术都存在显示均匀性或稳定性的问题，而且OLED本身也会随着点亮时间的增加亮度逐渐衰减。这些显示问题难以在工艺上完全克服，一般通过在设计上采用各种补偿技术来消除上述因素的影响，最终让所有像素的亮度达到理想值。目前常用的补偿形式有内部补偿和外部补偿。
内部补偿是在补偿阶段把TFT的阈值电压（V th）先储存在它的栅源电压（V gs）内，在发光时把V gs-V th转化为电流，由于V gs已经含有了V th，在转化成电流时就把V th的影响抵消了，从而实现了电流的一致性。但是，实际因为寄生参数和驱动速度等影响，V th并不能完全抵消，也即当V th偏差超过一定范围时（通常∆V th≥0.5V），电流的一致性无法确保了，因此内部补偿的补偿范围是有限的。外部补偿根据数据抽取方法的不同又可以分为光学抽取式（Demura，光学补偿）和电学抽取式。光学抽取式是指将背板点亮后通过光学CCD（Charge Coupled Device，电荷耦合器件）照相的方法将亮度信号抽取出来，电学抽取式是指通过驱动芯片的感应电路将TFT和OLED的电学信号抽取出来；两种方法抽取的信号种类不同，因此数据处理的方式也不同。光学抽取的方式具有结构简单，方法灵活的优点，因此在现阶段被广泛采用。
传统的Demura补偿技术需用到精细复杂的外围设备（如AOI，Automated Optical Inspection，自动光学检测），使得补偿过程较复杂，另外，传统的Demura补偿技术局限于显示面板制造厂内，而显示面板在使用过程产生的器件老化导致的显示不均的问题无法进行二次补偿，一定程度上降低了产品可靠性。因此，急需开发一种可以对显示面板进行实时Demura补偿的技术。

传统的亮度补偿（Demura)的主要步骤为：通过驱动芯片驱动点亮显示面板，并显示数个画面（一般是灰阶或者RGB）；使用高分辨率和高精度的CCD照相机拍摄上述画面；根据照相机采集的数据分析子像素的颜色分布特征，并根据相关算法识别出Mura；根据实际亮度数据、预设亮度数据及相应的亮度补偿算法产生亮度补偿数据；将亮度补偿数据烧录到Flash ROM（闪存）中并根据亮度补偿数据对显示面板进行亮度补偿，重新拍摄补偿后画面，确认Mura已消除。
由于传统的亮度补偿技术需用到精细复杂的外围设备（如AOI），使得补偿过程较复杂，另外，传统的亮度补偿技术局限于显示面板制造厂内，而显示面板在使用过程产生的器件老化导致的显示不均的问题无法进行二次补偿，一定程度上降低了产品可靠性。因此，急需开发一种可以对显示面板进行实时亮度补偿的技术。
如图1至图2所示，本申请实施例提供了一种显示面板1，包括呈阵列分布的多个显示单元2，每个显示单元2包括同层设置的显示器件3和感光器件4；每个显示单元2的一侧设置有反光单元5（反光单元5位于显示单元2的出光侧），用于将显示器件3发出的光部分反射至感光器件4，以检测显示器件3发出的光的亮度数据。
具体的，显示器件3包括有机电致发光二极管（OLED），当然还可以是Micro LED或其他类型的显示器件，此处不做限制；感光器件4包括有机光电二极管(OPD，Organic Photodiodes Diode)、非晶硅器件和互补金属氧化物半导体器件中的任意一种，当然还可以是其他可以将光信号转化为电信号的感光器件，此处不做限制；反光单元5的材料包括金属反光材料。
具体的，感光器件4接收到光信号后可以将光信号转化为电信号，以检测对应的显示器件3发出的光的亮度数据；需要说明的是，亮度数据与电信号之间为对应关系，不同的电信号对应不同的亮度数据；因此，感光器件4检测出的亮度数据为显示器件3发出的光的实际亮度大小，根据该亮度数据与预设亮度数据（正常显示时的亮度大小）进行对比分析可以判断是否存在亮度差异，即是否存在Mura，可以为亮度补偿操作提供可靠依据。
具体的，每个显示单元2还包括位于显示器件3和感光器件4之间的间隔单元6，反光单元5对应间隔单元6设置；反光单元5和显示单元2之间还设有薄膜封装层7，用于保护显示器件3和感光器件4；如图3所示，薄膜封装层7包括依次设置在显示单元2上的第一无机封装层8、有机封装层9和第二无机封装层10。当然，任意相邻的两个显示单元2之间也设有间隔单元6，间隔单元6的材料包括光阻材料。
具体的，每个反光单元5远离间隔单元6的一侧还设置有遮光单元11，遮光单元11的材料包括黑色色阻。在一实施例中，遮光单元11还对应感光器件4设置，避免环境光对感光器件4造成干扰，有利于提高检测的亮度数据的精确度。
具体的，如图3所示，每个显示单元2远离反光单元5的一侧设置有第一薄膜晶体管13和第二薄膜晶体管14；第一薄膜晶体管13与显示器件3连接，用于控制显示器件3工作；第二薄膜晶体管14与感光器件4连接，用于输出亮度数据。
具体的，显示器件3包括第一阳极15，以及依次设置在第一阳极15上的发光功能层16和阴极17；感光器件4包括第二阳极18，以及依次设置在第二阳极18上的感光功能层19和阴极17；其中，第一阳极15和第二阳极18的材料相同，且显示器件3和感光器件4共用同一层阴极17。第一薄膜晶体管13包括第一源极20、第一漏极21、第一栅极22和第一有源层23，其中，第一漏极21与第一阳极15通过过孔连接；第二薄膜晶体管14包括第二源极24、第二漏极25、第二栅极26和第二有源层27，其中，第二漏极25与第二阳极18通过过孔连接。第一源极20、第一漏极21、第二源极24和第二漏极25可在同一制程中采用相同的材料形成；第一栅极22和第二栅极26可在同一制程中采用相同的材料形成；第一有源层23和第二有源层27可在同一制程中采用相同的材料形成。
具体的，显示面板1还包括衬底基板28和设置在衬底基板28上的水氧阻挡层29，第一薄膜晶体管13和第二薄膜晶体管14位于水氧阻挡层29上；显示面板1还包括设置在第一栅极22和第一有源层23之间（第二栅极26和第二有源层27之间）的栅极绝缘层30，设置在第一栅极22和第一源极20、第一漏极21之间（第二栅极26和第二源极24、第二漏极25之间）的层间绝缘层31，以及设置在第一源极20、第一漏极21和第一阳极15之间（第二源极24、第二漏极25和第二阳极18之间）的平坦层32；间隔单元6设置在平坦层32上且部分覆盖在第一阳极15和第二阳极18上。
本实施例中，与现有的通过精细复杂的外围设备获取显示面板1的实际亮度相比，本申请实施例将每个显示单元2的感光器件4和显示器件3集成在同一显示面板1中，且每个显示器件3都对应一个感光器件4，通过对应的反光单元5，可以将每个显示器件3发出的光部分反射至对应的感光器件4，以获取每个显示器件3的发出的光的亮度数据，不需要使用精细复杂的外围设备就可以获得每个显示单元2的亮度数据，操作方便，且可以在显示面板1使用过程中实时检测每个显示单元2的亮度是否异常，为亮度补偿操作提供可靠的依据。
在一实施例中，每个显示单元2的一侧还设置有对应显示器件3设置的透光单元12；透光单元12与遮光单元11同层设置。具体的，透光单元12具有光波选择透过性，起到滤光的作用；不同的显示器件3可以发出不同颜色的光，例如红光、绿光和蓝光，对应的，发红光的显示器件3对应的透光单元12只允许红光透过，发绿光的显示器件3对应的透光单元12只允许绿光透过，发蓝光的显示器件3对应的透光单元12只允许蓝光透过。透光单元12和遮光单元11构成彩色滤光片，该彩色滤光片取代了原有的偏光片，即POL-Less（无偏光片）技术，该技术有利于减小显示面板1的厚度。
在一实施例中，反光单元5靠近间隔层的一侧为内凹弧面，使得一个感光器件4只接收对应的一个显示器件3发出的光信号，避免相邻的其他显示器件3发出的光信号进行干扰，有利于提高亮度数据的精确度。
如图4所示，本申请实施例还提供了一种显示装置33，包括上述实施例中所述的显示面板1，亮度补偿模块34和驱动模块35；亮度补偿模块34与每个显示单元2的感光器件4信号连接，用于获取亮度数据，并根据亮度数据输出亮度补偿数据；驱动模块35一端与亮度补偿模块34信号连接，另一端与显示面板信号连接，用于根据亮度补偿数据对显示面板1进行亮度补偿，具体的，根据亮度补偿数据对显示面板1中出现显示不均的显示单元2进行亮度补偿。
具体的，每个显示单元2的感光器件4将光信号转化为电信号后，通过对应的第二薄膜晶体管14将电信号输出至亮度补偿模块34；亮度补偿模块34获取每个显示单元2对应的亮度数据后，先根据每个显示单元2的预设亮度数据（正常显示时的亮度大小）进行分析判断每个显示单元2的亮度是否存在亮度差异，即对显示面板1进行Mura识别，然后结合显示面板1的驱动电流，通过相应的Demura补偿算法输出亮度补偿数据。
具体的，显示装置33还包括存储模块36，例如Flash ROM；存储模块36一端与亮度补偿模块34信号连接，另一端与驱动模块35信号连接；亮度补偿模块34输出的亮度补偿数据可以直接烧录至存储模块36；驱动模块35包括驱动芯片（Drive IC）；驱动模块35可以直接从存储模块36中读取亮度补偿数据，并根据亮度补偿数据对显示面板1的显示单元2进行亮度补偿。
具体的，亮度补偿数据包括待补偿的显示单元2的位置信息和补偿值，需要说明的是，亮度补偿数据可以包括每个显示单元2的位置信息和补偿值，此时，对于显示正常的显示单元2的补偿值可以设为零；当然，亮度补偿数据还可以只包括出现显示不均的显示单元2的位置信息和补偿值，此处不做限制。
具体的，亮度补偿模块34、存储模块36和驱动模块35可以集成在同一个电路板上，以减小显示装置33的体积。
具体的，本实施例的显示装置33可以实时进行亮度数据测定、Mura识别和亮度补偿操作以获得亮度均匀的显示效果；并且，可以对亮度补偿后的显示面板1的每个显示单元2进行再次检测，并判定补偿效果；还可以对显示面板1进行多次亮度补偿操作，并最终得到均匀的亮度显示；本实施例无需使用外围设备即可对显示面板1进行亮度补偿，且可随时随地对显示面板1进行亮度补偿，操作方便。
本实施例中，亮度补偿模块34可以根据每个感光器件4输出的亮度数据对每个显示器件的亮度进行分析，并通过补偿算法得到对应的亮度补偿数据，驱动模块35可以根据亮度补偿数据对相应的显示单元2进行亮度补偿，达到显示均匀的目的，上述亮度补偿过程可以在显示装置33使用过程中实时进行，且可以多次进行亮度数据检测以及亮度补偿操作，保证显示亮度均匀，提高了显示面板1性能的可靠性，即提升了显示装置33性能的可靠性。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
以上对本申请实施例所提供的一种显示面板和显示装置进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的技术方案及其核心思想；本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例的技术方案的范围。
