具体实施方式
针对常规技术中存在的显示设备不能有效地防偷窥的问题，本公开实施例提 供了一种显示面板、其驱动方法及防偷窥系统。
下面结合附图，对本公开实施例提供的显示面板及防偷窥系统的具体实施方式进行详细地说明。附图中各部件的厚度和形状不反映真实比例，目的只是示意说明本公开内容。
本公开实施例提供了一种显示面板，如图1至图4以及图6所示，包括：衬底基板100，以及以阵列形式排布于所述衬底基板100上的多个像素单元200。每个像素单元200包括：第一自发光器件101、第二自发光器件102和量子点发光器件103，所述第一自发光器件101和所述第二自发光器件102层叠设置于每个子像素区域201内，所述量子点发光器件103设置于至少两个子像素区域201内且设置于不同子像素区域201内的量子点发光器件103的发光颜色不同。
第一自发光器件101被配置为在一帧的显示时间段激发量子点发光器件103发光，以显示正常画面。第二自发光器件102被配置为在一帧的显示时间段期间处于关闭状态，以及在一帧的干扰时间段期间激发部分子像素区域201内的量子点发光器件103发光，以显示干扰画面。
本公开实施例提供的显示面板，在一帧的显示时间段，第一自发光器件101发光，第二自发光器件102处于关闭状态，以显示正常画面，在一帧的干扰时间段，第二自发光器件102发光，以显示干扰画面。观看者佩戴对应的快门眼镜可以滤除干扰画面，从而使观看者观看到正常画面，而没有佩戴快门眼镜的偷窥者，观看到的画面为显示画面和干扰画面叠加的画面，从而使偷窥者不能观看到显示面板显示的重要信息，从而实现了显示面板的防偷窥功能。
在一帧的显示时间内，正常画面和干扰画面交替出现，如图5所示(以两帧显示时间为例)，一般一帧的显示时间在
Figure PCTCN2017082197-appb-000001
对于人眼来说，不能分辨出显示时间段和干扰时间段的频繁变化，所以没有佩戴快门眼镜的偷窥者看到的图像为显示画面和干扰画面的叠加图像，可以通过控制显示干扰画面遮挡正常画面显示的重要信息的位置，例如在重要信息的位置显示马赛克的效果，或者显示花屏对正常画面进行干扰，以实现防偷窥的效果，并且在一帧的干扰时间段，可以控制部分的子像素区域201显示画面对重要信息的位置进行干扰，无需控制所有的子像素区域201进行显示。此外，在实际应用中，在一帧的显示时间内，显示时间段优选为大于干扰时间段，这样，可以保证观看者能够清晰的看到的正常画面。
在具体实施时，在一帧的干扰时间段，第一自发光器件101可以处于关闭状态，这样可以节省该显示面板的功耗，也可以设置第一自发光器件101一直处于开启状态，这样无需控制第一自发光器件101不断的开启和关闭，不仅可以简化了控制过程，也可以延长第一自发光器件101的寿命。此处并不对干扰时间段第一自发光器件101的状态进行限定。并且，图1至图4以及图6中以两个像素单元200为例进行说明，并不限定像素单元200的数量。
在实际应用中，本公开实施例提供的上述显示面板可以实现单面防偷窥显示，如图1、图2以及图6所示，在子像素区域201内设置的量子点发光器件103为一个；各量子点发光器件103设置于衬底基板100的同一侧，且位于第一自发光器件101和第二自发光器件102相对于衬底基板100的外侧；
各第一自发光器件101和各第二自发光器件102为面向量子点发光器件103的单向自发光器件。
通过将各量子点发光器件103设置在第一自发光器件101和第二自发光器件102相对于基板的外侧，并且各量子点发光器件103位于衬底基板100的同一侧，在一帧的显示时间段，第一自发光器件101激发各子像素区域201内的量子点发光器件103发光，从而实现显示正常画面，在一帧的干扰时间段，第二自发光器件102激发部分子像素区域201内的量子点发光器件103发光，从而实现显示干扰画面，即第一自发光器件101和第二自发光器件102共用量子点发光器件103。
此外，还需要设置各第一自发光器件101和各第二自发光器件102为面向量子点发光器件103的单向自发光器件，图1和图2示出的结构中，第一自发光器件101位于第二自发光器件102背离衬底基板100的一侧，即第二自发光器件102位于第一自发光器件101和衬底基板100之间，在具体实施时，也可以设置第一自发光器件101位于第二自发光器件102和衬底基板100之间，或者，也可以设置衬底基板100位于第一自发光器件101和第二自发光器件102之间，如图6所示(此时衬底基板100要求为透明基板)，此处并不对第一自发光器件101、第二自发光器件102以及衬底基板100的叠层位置进行限定。
在实际应用中，本公开实施例提供的上述显示面板也可以实现双面防偷窥显示，如图3和图4所示，在子像素区域201内设置的量子点发光器件103为两个，且分别设置于衬底基板100两侧且发光颜色相同；各量子点发光器件103分别位于第一自发光器件101和第二自发光器件102相对于衬底基板100的外侧；
各第一自发光器件101和各第二自发光器件102为双向发光的透明自发光器件。
通过在子像素区域201内设置两个量子点发光器件103，两个量子点器件分别位于衬底基板100两侧且发光颜色相同；各量子点发光器件103分别位于第一自发光器件101和第二自发光器件102相对于衬底基板100的外侧。在一帧的显示时间段，第一自发光器件101激发各子像素区域201内，且位于第一自发光器件101相对于衬底基板100外侧的量子点发光器件103发光，从而实现显示正常画面，在一帧的干扰时间段，第二自发光器件102激发部分子像素区域201内，且位于第二自发光器件102相对于衬底基板100外侧的量子点发光器件103发光，从而实现显示干扰画面，即第一自发光器件101和第二自发光器件102不共用量子点发光器件103。
此外，还需要设置各第一自发光器件101和各第二自发光器件102为双向发光的透明自发光器件，图3和图4示出的结构中，衬底基板100位于第一自发光器件101和第二自发光器件102之间，在具体实施时，也可以设置第一自发光器件101位于第二自发光器件102和衬底基板100之间，或者，也可以设置第二自发光器位于第一自发光器件101和衬底基板100件之间，此处并不对第一自发光器件101、第二自发光器件102以及衬底基板100的叠层位置进行限定。
在具体实施时，本公开实施例提供的上述显示面板中，各第一自发光器件101优选为位于衬底基板100的同一侧，且各第二自发光器件102优选为位于衬底基板100的另一侧，如图3、图4以及图6所示，其中图3和图4为双面防偷窥显示，图6为单面防偷窥显示。
在具体实施时，本公开实施例提供的上述显示面板中，各像素单元200还包括：在量子点发光器件103相对于衬底基板100的外侧设置的滤光层104，滤光层104用于滤除第一自发光器件101的发光。
以图1所示的结构为例，设置量子点器件是为了使量子点器件在第一自发光器件101的激发下，发出量子点器件对应颜色的光线，并不希望第一自发光器件101本身的光线也在量子点器件对应的位置出射，所以为了使正常画面的显示效果更好，在量子点发光器件103相对于衬底基板100的外侧优选设置滤光层104，以滤除第一自发光器件101激发量子点发光器件103后残留的光线。而对于为了显示干扰画面的第二自发光器件102，无需设置滤光层104滤除第二自发 光器件102的残留光线，因为第二自发光器件102的残留光线本身也可以起到干扰显示画面的效果。
如图1和图3所示，上述滤光层104设置在量子点发光器件103对应的位置处，对于图2和图4所示的结构，由于在每个像素单元200中，各子像素区域201都包含量子点发光器件103，所以上述滤光层104也可以整层设置。
在具体实施时，本公开实施例提供的上述显示面板中，第一自发光器件101的发光波长小于所有量子点发光器件103的发光波长。有两种实现方式：
第一种实现方式如图1和图3所示，第一自发光器件101为蓝光有机发光二极管(Organic Light-Emitting Diode，OLED)或蓝光发光二极管(Light Emitting Diode，LED)；量子点发光器件103为红光量子点发光器件103和绿光量子点发光器件103。
由于量子点发光器件103为红光量子点发光器件和绿光量子点发光器件103，为了实现三基色显示，第一自发光器件101优选为发蓝光。
以图1和图3为例，在具体实施时，在各像素单元200中，量子点发光器件103包括红光量子点发光器件103和绿光量子点发光器件103，而对于不包含量子点发光器件103的子像素区域201，在对应的位置可以设置透明器件300，以保证结构的平坦性。
第二种实现方式如图2和图4所示，第一自发光器件101为紫外有机发光二极管OLED或紫外发光二极管LED；量子点发光器件103为红光量子点发光器件103、绿光量子点发光器件103和蓝光量子点发光器件103。
量子点发光器件103为红光量子点发光器件103、绿光量子点发光器件103和蓝光量子点发光器件103，利用波长小于蓝光的光线可以激发各量子点发光器件103，从而实现三基色显示，一般用紫外光对各量子点发光器件103进行激发。
在具体实施时，本公开实施例提供的上述显示面板中，第二自发光器件102的发光波长大于至少一个量子点发光器件103的发光波长。这样第二自发光器件102可以激发至少一个量子点发光器件103发光，相对于使用第二自发光器件102发出的单一颜色的光线显示干扰画面。使用至少两种颜色的光线显示干扰画面的干扰效果更好。
对于图1和图3所示的结构，第二自发光器件102的发光波长大于至少一个量子点发光器件103的波长，即第二自发光器件102的发光波长大于绿光的波长 小于红光的波长，此时，第二自发光器件102只能激发红光量子点发光器件103，从而在显示干扰画面时，各像素单元200可能出现第二自发光器件102发光的颜色、红色或者二者叠加颜色。
对于图2和图4的结构，第二自发光器件102的发光波长大于至少一个量子点发光器件的波长，包括第二自发光器件102的发光波长大于蓝光的波长小于绿光的波长，以及大于绿光的波长小于红光的波长两种情况。第二自发光器件102的发光波长大于蓝光的波长小于绿光的波长时，第二自发光器件102可以激发红光量子点发光器件103和绿光量子点发光器件103，从而在显示干扰画面时，各像素单元200可能出现第二自发光器件102发光的颜色、红色、绿色或者三种颜色叠加的颜色；第二自发光器件102的发光波长在大于绿光的波长小于红光的波长时，第二自发光器件102只能激发红光量子点发光器件103，从而在显示干扰画面时，各像素单元200可能出现第二自发光器件102发光的颜色、红色或者二者叠加颜色。
在具体实施时，本公开实施例提供的上述显示面板中，上述第二自发光器件102优选为黄光有机发光二极管OLED或黄光发光二极管LED。
基于同一构思，本公开实施例还提供了一种上述显示面板的驱动方法，如图7所示，包括：
S101、在一帧的显示时间段期间，驱动各子像素区域的第一自发光器件处于开启状态，以及驱动各子像素区域的第二自发光器件处于关闭状态；
S102、在一帧的干扰时间段期间，驱动各子像素区域中的部分子像素区域中的第二自发光器件处于开启状态。
本公开实施例提供上述显示面板的驱动方法，通过在一帧的显示时间段，根据所需显示的正常画面，控制各子像素区域的第一自发光器件的开启状态，以及关闭所有第二自发光器件；控制各子像素区域的第二自发光器件随机开启，以显示花屏作为干扰画面。使观看者佩戴对应的快门眼镜可以滤除干扰画面，以观看到正常画面，而没有佩戴快门眼镜的偷窥者，观看到的画面为显示画面和干扰画面叠加的画面，从而使偷窥者不能观看到显示面板显示的重要信息，从而实现了显示面板的防偷窥功能。
上述步骤S102中并没有限定第一自发光器件的状态，即第一自发光器件在一帧的干扰时间段可以开启也可以关闭。在一帧的干扰时间段第一自发光器件为 开启状态时，第一自发光器件一直处于开启状态时，这样无需控制第一自发光器件不断的开启和关闭，不仅可以简化控制过程，而且可以延长第一自发光器件的使用寿命；在一帧的干扰时间段第一自发光器件为关闭状态时，可以节省显示面板的功耗。
基于同一构思，本公开实施例提供了一种防窥系统，包括：根据以上各实施例所述的显示面板；以及快门眼镜，所述快门眼镜的镜片被配置为在一帧的显示时间段期间处于透光状态，在一帧的干扰时间段期间处于不透光状态。
通过控制快门眼镜在一帧的显示时间段处于透光状态，以及在一帧的干扰时间段处于不透光状态，从而滤除显示面板在干扰时间段显示的干扰画面，从而使佩戴该快门眼镜的观看者能够看到显示面板显示的正常画面，而没有佩戴快门眼镜的偷窥者看到的画面为正常画面和干扰画面的叠加，从而使偷窥者不能观看到显示面板显示的重要信息，从而实现了显示装置的防偷窥功能。
本公开实施例提供的显示面板、其驱动方法及防偷窥系统，在一帧的显示时间段，第一自发光器件发光，第二自发光器件处于关闭状态，以显示正常画面，在一帧的干扰时间段，第二自发光器件发光，以显示干扰画面。观看者佩戴对应的快门眼镜可以滤除干扰画面，从而使观看者观看到正常画面，而没有佩戴快门眼镜的偷窥者，观看到的画面为显示画面和干扰画面叠加的画面，从而使偷窥者不能观看到显示面板显示的重要信息，从而实现了显示面板的防偷窥功能。
显然，本领域的技术人员可以对本公开进行各种改动和变型而不脱离本公开的精神和范围。这样，倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内，则本公开也意图包含这些改动和变型在内。
