Description

防窥功能结构、显示面板及显示设备
本申请要求于2021年11月29日提交中国专利局、申请号为202111438234.0、申请名称为“防窥功能结构、显示面板及显示设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请属于显示技术领域，尤其涉及一种防窥功能结构、显示面板及显示设备。
背景技术
目前由于人的领地意识越来越强，作为隐私较多的一个载物——手机，也需要有防止偷窥的功能，防窥膜就诞生了。防窥膜相当于在手机钢化膜中加入了防窥涂层，使用的是微细百叶窗光学技术。其原理类似于办公室里的百叶窗，通过调整角度可以实现不同的观感。但手机防窥膜的设计结构更加密集，可以理解为把百叶窗缩小几万倍，通过光线的角度控制，以使手机屏幕的可视角度变窄。
但是贴了防窥膜也有较多的不便，别人必须跟你处于同一角度，才能看清手机屏幕上的内容。比如在几人同时看一个屏幕时，由于其防窥特性，无法使得所有人能同时看到屏幕里的内容，影响了使用便利性。
发明内容
本申请提供了一种能够提高使用便利性的防窥功能结构、显示面板及显示设备。
一方面，本申请提供了一种防窥功能结构，包括防窥状态和非防窥状态，所述防窥功能结构还包括：
第一导电层；
防窥液晶层，设于所述第一导电层的一侧；
透光盖板，设于所述防窥液晶层背离所述第一导电层的一侧；以及
第二导电层，设于所述透光盖板朝向所述第一导电层的一侧；所述第二导电层包括多个相互平行的导电条；
通过控制多个所述导电条的通断电，使所述防窥功能结构在所述防窥状态与所述非防窥状态之间进行切换。
另一方面，本申请提供了一种显示面板，包括层叠设置的显示层与所述防窥功能结构，所述防窥功能结构包括防窥状态和非防窥状态，所述防窥功能结构还包括：
第一导电层，贴合于所述显示层上；
防窥液晶层，设于所述第一导电层的一侧；
透光盖板，设于所述防窥液晶层背离所述第一导电层的一侧；以及
第二导电层，设于所述透光盖板朝向所述第一导电层的一侧；所述第二导电层包括多个相互平行的导电条；
通过控制多个所述导电条的通断电，使所述防窥功能结构在所述防窥状态与所述非防窥状态之间进行切换。
再一方面，本申请提供了一种显示设备，包括所述显示面板及处理器，所述显示面板包括层叠设置的显示层与防窥功能结构，所述防窥功能结构包括防窥状态和非防窥状态，所述防窥功能结构还包括：
第一导电层，贴合于所述显示层上；
防窥液晶层，设于所述第一导电层的一侧；
透光盖板，设于所述防窥液晶层背离所述第一导电层的一侧；以及
第二导电层，设于所述透光盖板朝向所述第一导电层的一侧；所述第二导电层包括多个相互平行的导电条；
通过控制多个所述导电条的通断电，使所述防窥功能结构在所述防窥状态与所述非防窥状态之间进行切换；
所述处理器与所述第一导电层电连接，所述处理器与所述第二导电层电连接，所述处理器与所述显示面板电连接。
本申请提供的防窥功能结构、显示面板及显示设备，具有相对设置的第一导电层及第二导电层，且第二导电层包括多个导电条，通过控制导电条的通断电，可以控制防窥液晶层中的液晶分子的偏转。当至少一个导电条通电时，导电条与第一导电层之间形成电场，防窥液晶层中的液晶分子在电场力的作用下发生偏转，防窥液晶层不可透光，此时防窥功能结构处于防偷窥状态。当多个导电条上都不通电时，防窥液晶层中的液晶分子无电场力作用，防窥液晶层可以透光，此时防窥功能结构处于非防偷窥状态。本申请提供的防窥功能结构、显示面板及显示设备可以切换防窥状态与非防窥状态，以便于用户在不同的使用环境下根据需要切换防窥功能结构、显示面板及显示设备的状态。

具体实施方式
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。本申请实施方式相互适应性地结合，其结合所形成的新的实施方式也是本申请所保护的范围内。
请参阅图1，图1是本申请实施例提供的一种显示设备的示意图。
显示设备300包括显示面板100及处理器200，处理器200与显示面板100电性连接。通过处理器200与显示面板100电性连接，以控制显示面板100。
请结合参阅图2，图2是本申请实施例提供的一种显示面板的的剖面图。
显示面板100包括防窥功能结构10及显示层20，防窥功能结构10与显示层20层叠设置。显示层20用于显示图像。防窥功能结构10盖设于显示层20上。防窥功能结构10用于防偷窥，以对显示层20的显示内容进行隐私保护。显示层20与处理器200电连接，防窥功能结构10与处理器200电连接。
防窥功能结构10包括防窥状态与非防窥状态。防窥功能结构10处于防窥状态下时，显示层20显示内容在可视角度可视。可视角度即为用户能够通过防窥功能结构10看到的显示层20上的显示内容的角度。防窥功能结构10处于非防窥状态下时，防窥功能结构10类似透光玻璃，非防窥状态下的防窥功能结构10无防窥功能，显示层20显示的图像可正常透过防窥功能结构10。处理器200用于控制防窥功能结构10在防窥状态与非防窥状态之间进行切换。本实施方式中，防窥状态包括第一防窥状态、第二防窥状态。防窥功能结构10在不同的防窥状态下时，防窥功能结构10的可视角度不同。处理器200还用于控制防窥功能结构10在不同的防窥状态下进行切换。
以手机作为显示设备300举例，当用户在公共场所需要在手机里查看个人隐私界面时，用户可以通过处理器200将手机里的防窥功能结构10设置成防窥状态，以使手机的显示面板100的显示层20在可视角度可视。当用户在需要共享手机里的界面信息时，用户可以通过处理器200将手机里的防窥功能结构10设置成非防窥状态，以使手机的显示面板100的显示层20上的图像正常透过防窥功能结构10，进而使得手机的显示面板100对多人可视。
当用户需要对防窥功能结构10的状态进行切换或设置时，用户可以通过应用程序(application，APP)、机械按键等方式进行触发请求，处理器200根据用户的触发请求，控制切换防窥功能结构10的状态，例如从防窥状态切换为非防窥状态，或者，从非防窥状态切换为防窥状态。可以理解的，在防窥状态下，用户可以通过处理器200切换手机的防窥功能结构10的第一防窥状态和第二防窥状态，在第一防窥状态和第二防窥状态下的显示面板100的可视角度不同，以便于用户在不同的角度范围内控制显示面板100显示的的内容。
可选的，显示设备300包括但不限于手机、电脑、电视机、智能穿戴设备等具有发光显示效果的设备。
具体的，请参阅图2，显示层20包括阵列基板201、彩膜基板202及混色液晶层203，混色液晶层203设于阵列基板201与彩膜基板202之间，混色液晶层203用于控制显示层20的混色显示。阵列基板201上设有导电胶层2011及公共电极2012，导电胶层2011连接于防窥功能结构10与公共电极2012之间，以使防窥功能结构10与公共电极2012实现跨层电性连接。需要理解的 是，跨层电性连接指的是防窥功能结构10与阵列基板201的公共电极2012连接跨越彩膜基板202与混色液晶层203。
公共电极2012用于导入平稳的电信号，一方面，使防窥功能结构10的一侧导入稳定的电信号，进而形成稳定电压。另一方面，屏蔽外部电场的影响，以使混色液晶层203的显示稳定性更好。
可选的，导电胶层2011的材质包括但不限于银胶等其他具有导电性的材料。
请结合参阅图3及图4，图3是本申请实施例提供的一种防窥功能结构的剖面图，图4是本申请实施例提供的一种防窥液晶层的剖面图。
防窥功能结构10包括第一导电层1、透光盖板2、第二导电层3、防窥液晶层4、控制电路5及反馈电路6。
第一导电层1与透光盖板2相对设置，第二导电层3设于透光盖板2朝向第一导电层1的一侧。第一导电层1与第二导电层3间隔设置，防窥液晶层4设于第一导电层1与第二导电层3之间。
控制电路5与处理器200电性连接。控制电路5与第二导电层3电性连接，控制电路5用于分别控制设于第二导电层3上的多个导电条31上电信号的通断(即通断电)。处理器200接收用户的触发请求时，通过控制电路5控制各导电条31上电信号的通断，使防窥功能结构10切换至相应状态。
反馈电路6电性连接于处理器200与第二导电层3之间，反馈电路6用于监测设于第二导电层3上的多个导电条31上的电信号，并将第二导电层3上的多个导电条31的通断电情况反馈至处理器200。当反馈电路6检测到所有导电条31皆通电或者仅部分电条31皆通电时，处理器200可以生成防窥功能结构10在防窥状态下的不同可视角度信息。通过反馈电路6的设置，以实现对防窥功能结构10在防窥状态下的可视角度进监测。
在其他的实施方式中，控制电路5与反馈电路6可以设于处理器200内。
具体的，防窥液晶层4包括第一导向膜41、第二导向膜42及防窥液晶分子43，防窥液晶分子43夹设于第一导向膜41与第二导向膜42之间。第一导向膜41设于防窥液晶层4靠近第一导电层1的一侧，第二导向膜42设于防窥液晶层4靠近第二导电层3的一侧，第一导向膜41与第二导向膜42用于锚定防窥液晶分子43，以使液晶分子43处于固定的偏转角度，且形成的防窥液晶层4透光。
本实施例中，第一导电层1的材质为氧化铟锡(ITO)，第一导电层1设于彩膜基板202背离混色液晶层203的一侧，第一导电层1呈薄膜状，第一导电层1上可承载电信号。第一导电层1通过导电胶层2011与公共电极2012电性连接，通过公共电极2012对第一导电层1导入平稳的电信号，以使第一导电层1上形成稳定的电压。
本实施例中，第二导电层3可的材质为氧化铟锡(ITO)，第二导电层3设于透光盖板2靠近防窥液晶层4的一侧，第二导电层3包括多个间隔设置的导电条31，导电条31呈竖条状，导电条31上可承载电信号。
具体的，多个导电条31之间间隔设置，且相邻的两个导电条31之间的间距相等。通过相邻的两个导电条31之间的间距相等设置，以使防窥液晶层4上的液晶分子43偏转均匀，提高防窥液晶层4的稳定性，进而提高防窥功能结构10的显示效果。多个导电条31上的电信号大小相等，且相邻的导电条31上的电信号方向相反。通过多个导电条31上的电信号大小相等的设置，以使防窥液晶层4上的液晶分子43偏转均匀，提高防窥液晶层4的稳定性，进而提高防窥功能结构10的显示效果。通过相邻的导电条31上的电信号方向相反设置，以使相邻的导电条31之 间形成第一方向的电场，进而减小导电条31影响透光部分的液晶分子43的偏转，提高防窥液晶层4的透光性能，进而提高防窥功能结构10的显示效果。
在其他实施例中，第一导电层1及第二导电层3的材质可以是其他具有导电性的材料。
在其他实施例中，请结合参阅图5，图5是本申请实施例提供的另一种防窥功能结构的剖面图。图5所示的防窥功能结构10与图3所示的防窥功能结构10大致相同，其不同之处在于，图5所示的防窥功能结构10中，多个导电条31之间不等间距设置。
具体的，多个导电条31中，靠近透光盖板2中间部位的相邻的两个导电条31之间的间距大于靠近透光盖板2边缘部位的相邻的两个导电条31之间的间距。换而言之，靠近透光盖板2中间部位的相邻的两个导电条31至靠近透光盖板2边缘部位的相邻的两个导电条31呈递减形式。通过靠近透光盖板2中间部位的相邻的两个导电条31之间的间距大于靠近透光盖板2边缘部位的相邻的两个导电条31之间的间距，靠近透光盖板2边缘部位的可视角度减小，以使防窥功能结构10的防窥效果更好。
下面分别对防窥功能结构10的防窥状态与非防窥状态作进一步阐述。
请结合参阅图6，图6是本申请实施例提供的一种防窥功能结构在防窥状态的电场分布图。
当防窥功能结构10处于防窥状态时，控制电路5控制第二导电层3上的导电条31，并使得至少一个导电条31通电。通过至少一个导电条31与第一导电层1之间形成第一方向(如图6所示的竖直箭头方向)的电场，以使该通电导电条31与第一导电层1之间的液晶不可透光。
具体的，透光盖板2包括第一区域21与第二区域22，第一区域21的数量为多个，导电条31对应第一区域21设置，多个导电条31分别覆盖于多个第一区域21上。相邻的两个第一区域21之间为第二区域22，第二区域22对应相邻的两个导电条31之间的间隙。
请结合参阅图7及图8，图7是本申请实施例提供的防窥功能结构在第一防窥状态的示意图，图8是本申请实施例提供的防窥功能结构在第一防窥状态的透光示意图。
通过控制电路5控制不同的导电条31的通断电，使防窥功能结构10在不同的防窥状态下进行切换。
控制电路5控制每一个导电条31上皆通电，相邻的两个导电条31上的电信号大小相等，方向相反，防窥功能结构10处于第一防窥状态。多个导电条31分别与第一导电层1之间形成第一方向的电场，相邻的两个导电条31之间因为电信号方向相反而形成第二方向(如图6所示的水平箭头方向)的电场。
防窥液晶层4内的液晶分子43处于第一方向的电场中不可透光，防窥液晶层4内的液晶分子43处于第二方向的电场中可透光。换而言之，第一区域21对应的液晶分子43不可透光，第二区域22对应的液晶分子43可透光。
防窥功能结构10在第一防窥状态下，防窥功能结构10仅第二区域22(即相邻的两个导电条31之间的间隙)可透光，防窥功能结构10的可视角度为α1，便于用户在查看隐私界面，且用户可以根据隐私界面的重要程度通过反馈电路6调节防窥功能结构10的防窥程度。防窥程度即液晶分子43的偏转角度，当反馈电路6控制导电条31上的电信号较大时，该区域内的液晶分子43的偏转角度较大，其透光性较差，当反馈电路6控制导电条31上的电信号较小时，该区域的液晶分子43的偏转角度较小，其透光性较好。应该理解的是，透光性较好与透光性较差指的是液晶分子43的透光率，透光性好指的是该区域的液晶分子43透光率高，透光性差指的是该区域的液晶分子43透光率低。
请结合参阅图9、图10、图11及图12，图9是本申请实施例提供的第一种防窥功能结构在 第二防窥状态的示意图，图10是本申请实施例提供的第一种防窥功能结构在第二防窥状态的透光示意图，图11是本申请实施例提供的第二种防窥功能结构在第二防窥状态的示意图，图12是本申请实施例提供的第二种防窥功能结构在第二防窥状态的透光示意图。
在第二防窥状态中，控制电路5控制部分导电条31通电，通电的导电条31上的电信号大小相等，且通电的相邻的两个导电条31上的电信号方向相反。通电的导电条31与第一导电层1之间形成第一方向的电场，通电的相邻的两个导电条31之间形成第二方向的电场。
防窥液晶层4内的液晶分子43处于第一方向的电场中不可透光，防窥液晶层4内的液晶分子43处于第二方向的电场中可透光。换而言之，通电的导电条31对应的第一区域21中的液晶分子43不可透光，断电导电条31对应的第一区域21中的液晶分子43可透光，第二区域22对应的液晶分子43可透光。
防窥功能结构10在第二防窥状态下，防窥功能结构10部分第一区域21及第二区域22可透光，防窥功能结构10在第二防窥状态下的可视角度为α2，并且α2＞α1。
请参阅图3、图9及图10，在第一种实施方式中，控制电路5控制多个导电条31每隔一个的导电条31通电，即通电的导电条31、断电的导电条31、通电的导电条31、断电的导电条31……依次间隔设置。防窥功能结构10在第一种实施方式中的可视角度为α2，且α2＞α1。防窥液晶层4中的液晶分子43偏转均匀，以使防窥功能结构10的显示效果更均匀。
请参阅图3、图11及图12，在第二种实施方式中，控制电路5控制部分相邻的导电条31通电，控制电路5控制另一部分相邻的导电条31断电，即通电的导电条31、通电的导电条31、通电的导电条31……、断电的导电条31、断电的导电条31、断电的导电条31……依次间隔设置。防窥功能结构10在第二实施方式中的可视角度在不同区域不同，即可视角度包括α1和α2，有利于用户选择性地控制防窥功能结构10部分区域的可视角度为α2，另一部分区域的可视角度为α1。防窥功能结构10在第二种实施方式中，有利于用户在防窥状态下可以调整防窥功能结构10在不同区域的可视角度，提升用户的使用体验。
可以理解的，用户可以通过处理器200控制防窥功能结构10上不同区域呈现不同的透光效果，进而实现调节手机显示面板100上不同区域对应不同的显示状态。例如：防窥功能结构10包括可视区和不可视区，显示面板100的顶部一般会弹出短信、消息、通知等包括个人隐私的界面，用户可以将手机的显示面板100的顶部对应防窥功能结构10的不可视区设置，而将其他部分设置成防窥功能结构10的可视区，以使用户在保护自己的隐私信息的同时可以将需要共享的界面进行共享。
请结合参阅图13及图14，图13是本申请实施例提供的防窥功能结构在非防窥状态的示意图，图14是本申请实施例提供的防窥功能结构在非防窥状态的透光示意图。
当防窥功能结构10处于非防窥状态时，控制电路5控制第二导电层3上的导电条31，并使得每一个导电条31断电。防窥液晶层4中的所有液晶分子43皆可透光，此时防窥功能结构10类似于普通的透光玻璃，呈非防窥状态。
在本申请实施例提供的防窥功能结构10、显示面板100及显示设备300中，用户可以通过控制电路5控制第二导电层3上导电条31的电信号的通断，可以实现防窥功能结构10在防窥状态与非防窥状态的切换。用户还可以通过控制电路5控制第二导电层3上部分导电条31的电信号的通断，可以实现防窥功能结构10在防窥状态下切换第一防窥状态与第二防窥状态。
以上是本申请的部分实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本申请的保 护范围。
