为了保持本公开实施例的以下说明清楚且简明，本公开省略了已知功能和已知构件的详细说明。
显示产品的上边框需要安装环境光传感器，盖板上侧则需要同步预留红外线(Infrared Radiation，IR)孔丝印区域，上边框缩窄受限。为了达到继续缩短模组边框及减少成本的目的，提出将整机的环境光调节功能集成在模组产品上，利用薄膜晶体管(Thin Film Transistor，TFT)器件的光敏特性实现环境光的检测，整机中可以取消上侧需预留的环境光模块区域，缩短边框以及降低成本，但由于TFT器件的金属层存在反光现象，在暗屏的状态下会看到由于金属层反光形成的一条亮线。

在具体实施时，结合图1、图2、图3、图4所示，显示装置包括位于显示基板1显示侧的盖板2，以及位于盖板2与显示基板1之间的对向基板3，盖板2在与边框区域BB对应的区域具有油墨21，对向基板3具有黑矩阵31；
遮光部4可以设置于盖板2，遮光部4在显示基板1的正投影与油墨21在显示基板1的正投影互不交叠(在其他实施例中也可以交叠)，黑矩阵31在与遮光部4对应的区域具有第一镂空部310；具体的，遮光部4在显示基板1的正投影可以覆盖环境光检测构件11在显示基板1的正投影，遮光部4在显示基板1的正投影可以覆盖第一镂空部310在显示基板1的正投影；具体的，遮光部4在显示基板1的正投影也可以与环境光检测构件11在显示基板1的正投影互相重合，遮光部4在显示基板1的正投影也可以与第一镂空部310在显示基板1的正投影互相重合；
或者，遮光部4也可以设置于对向基板3，如图4所示，遮光部4在显示基板1的正投影与黑矩阵31在显示基板1的正投影互不交叠(在其他实施例中也可以交叠)，油墨21在与遮光部4对应的区域具有第二镂空部210；具体的，遮光部4在显示基板1的正投影可以覆盖环境光检测构件11在显示基板1的正投影，遮光部4在显示基板1的正投影可以覆盖第二镂空部210在显示基板1的正投影；具体的，遮光部4在显示基板1的正投影也可以与环境光检测构件11在显示基板1的正投影互相重合，遮光部4在显示基板1的正投影也可以与第二镂空部210在显示基板1的正投影互相重合。
在具体实施时，对向基板可以为彩膜基板，显示基板可以为阵列基板。
在具体实施时，遮光部4可以设置于盖板2，具体的，可以设置于盖板2的面向显示基板1的一侧，遮光部4的透光率高于油墨21的透光率。具体的，遮光部4也可以设置于对向基板3的面向显示基板1的一侧，与黑矩阵31位 于对向基板3的相同侧，遮光部4的透光率高于黑矩阵31的透光率。具体的，遮光部4也可以为一种黑矩阵，但形成遮光部4的黑矩阵的透光率要高于常规的黑矩阵。具体的，图4中黑矩阵31可以为常规的黑矩阵。具体的，可以通过两次图案化工艺形成黑矩阵31和遮光部4。
具体的，遮光部4、油墨21的成分可以相同，即，遮光部4也可以为一种油墨，但该油墨的透光率要高于常规油墨的透光率，油墨32可以为常规油墨；遮光部4、油墨21均含有环氧树脂，且遮光部4中的环氧树脂的质量比例，高于油墨21中的环氧树脂的质量比例。具体的，例如，油墨21中环氧树脂的质量比例为8％～19％，遮光部4中环氧树脂的质量比例为40％～70％。
在一种可能的实施方式中，遮光部4的透光率为油墨21透光率的50～70倍。
在一种可能的实施方式中，遮光部4的透光率为50％～70％。具体的，遮光部4的透光率为60％。具体的，遮光部4的透光率可以理解为是对可见光的透光率，例如，是对550nm的光的透光率。
在一种可能的实施方式中，结合图2所示，油墨21位于盖板2的面向显示基板1的一侧。
在一种可能的实施方式中，在将遮光部4设置于盖板2时，结合图1和图5所示，其中，图5为图1在对应环境光检测构件11位置处的放大结构示意图，环境光检测构件11所在的边框区BB为第一边框区BB1；遮光部4在垂直于第一边框区BB1延伸方向DD上的宽度d1为0.3mm～0.9mm。具体的，遮光部4在垂直于第一边框区BB1延伸方向DD上的宽度d1为0.3mm～0.5mm。具体的，遮光部4在垂直于第一边框区BB1延伸方向DD上的宽度d1为0.4mm。本公开实施例中，遮光部4在垂直于第一边框区BB1延伸方向DD上的宽度d1为0.3mm～0.9mm，可以实现将环境光检测构件11所在区域进行完全覆盖。
在一种可能的实施方式中，结合图5、图6、图7所示，遮光部4具有朝向显示区AA的第一边界b，显示区AA具有朝向第一边框区BB1的第二边 界a，第一边界b与第二边界a之间的间距d2大于等于零且小于0.18mm。具体的，第一边界b与第二边界a之间的间距d2大于等于零且小于0.17mm。在具体实施时，可以通过丝印工艺形成遮光部4，由于油墨丝印工艺设备的定位公差为±0.08，60％透光率的遮光部4宽度公差±0.08、显示面板(包括显示基板和对向基板)与盖板的贴合公差±0.1，通过累计公差计算，环境光检测构件11所在区域的下侧(也即环境光检测构件11所在凹槽110的下边界)与遮光部4下边界的距离
Figure PCTCN2021082119-appb-000001
的距离，60％透过率的油墨区域才可以完全盖住环境光，即60％透光率的遮光部4上下左右均需要覆盖环境光0.13mm才能完全覆盖住环境光检测构件11。具体的，例如，结合图5、图6和图7所示，其中，图6为显示基板设置环境光检测构件11处的放大结构示意图，图7为包含环境光检测构件11以及遮光部4的局部放大示意图，环境光检测构件11所在区域的下侧(也即环境光检测构件11所在凹槽110的下边界)与显示区AA的上边界a的距离d3为301μm(也即0.301mm)，使用60％的遮光部4覆盖环境光检测构件11所在区域，60％透光率的遮光部4下边界距离凹槽110的下边界之间的距离d4为0.13mm(即60％透光率的遮光部4上下左右均需要覆盖环境光0.13mm才能完全覆盖住环境光检测构件11)，则60％的遮光部4下边界与显示区AA的上边界a的距离d2为0.17mm。当然，由于实际工艺误差波动，遮光部4也可能将凹槽110的下边界与显示区AA的上边界a之间的区域完全覆盖，即，d2也可以等于0。
在一种可能的实施方式中，环境光检测构件11包括400～600个第一晶体管。本公开实施例中，环境光检测构件11包括400～600个第一晶体管，可以改善因环境光检测构件11对应区域设置遮光部4时，入射的光被部分遮挡，导致检测到的信号较弱的问题，也即避免60％透光率的遮光部4带来亮度损失导致的检测到的信号较弱的问题。
在一种可能的实施方式中，结合图8所示，第一晶体管T1的栅极连接于同一第一栅线G1，第一晶体管T1的第一极连接于同一数据线S，第一晶体管 T1的第二极连接于同一第一信号读出线I1。
在一种可能的实施方式中，结合图1、图3和图4所示，显示装置还包括集成于显示基板边框区BB的对比检测构件12；黑矩阵层31在显示基板1的正投影覆盖对比检测构件12在显示基板1的正投影。本公开实施例中，显示装置还包括集成于显示基板边框区BB的对比检测构件12，可以通过环境光检测构件11检测到的信号与比检测器件12检测到的信号进行对比来获取外界光的变化，提高环境光的检测准确性。
在一种可能的实施方式中，结合图8所示，对比检测构件12包括多个第二晶体管T2，对比检测构件12包括的第二晶体管T2的数量与环境光检测构件11包括的第一晶体管T1的数量相同。需要说明的是，图8是以环境光检测构件11包括3个第一晶体管T1，对比检测构件12包括3个第二晶体管T2为例进行的示意说明，本公开实施例不以此为限。
在一种可能的实施方式中，第二晶体管T2的栅极连接于同一第二栅线G2，第二晶体管T2的第一极连接于同一数据线S，第二晶体管T2的第二极连接于同一第二信号读出线I2。
在具体实施时，考虑工艺造成的第一晶体管T1、第二晶体管T2阻抗差异，第一晶体管T1/第二晶体管T2均采用并联,减小个体差异。
在一种可能的实施方式中，结合图8所示，多个第一晶体管T1、多个第二晶体管T2呈一行排布。
在一种可能的实施方式中，参见图9所示，第一晶体管T1、第二晶体管T2均包括位于衬底基板100一侧的有源层104，有源层104具体可以为光敏层，在受光照射时产生光生载流子。
在一种可能的实施方式中，有源层104包括沟道区1041；第一晶体管T1、第二晶体管T2还均包括位于有源层104的背离盖板2一侧的栅极102，栅极102在显示基板1的正投影覆盖沟道区1041在显示基板1的正投影。本公开实施例中，栅极102在显示基板1的正投影覆盖沟道区1041在显示基板1的正投影，可以背光发光对环境光检测构件11以及对比检测器件12光检测的 影响。
在具体实施时，结合图9所示，第一晶体管T1、第二晶体管T2还均包括位于栅极102与衬底基板100之间的第一电极层101(第一电极层101的材质可以为氧化铟锡)，栅极102与有源层104之间还可以设置有栅极绝缘层103，有源层104的背离栅极绝缘层103的一侧还可以设置有数据信号线105(该数据信号线105可以作为数据线S)以及漏极106，数据信号线105的背离有源层104的一侧还可以设置有钝化层107，钝化层107的背离数据信号线105的一侧还可以设置有第二电极层108(第二电极层108的材质可以为氧化铟锡)。
