背景技术
目前，显示和照明技术领域是分开的，比如家用照明设备与显示设备是相互独立的两类产品，二者分别仅具有单一功能。例如，诸如电视机之类的显示设备一般仅用于显示功能，而无法实现照明功能。然而，事实上，显示技术和照明技术之间存在着密不可分的联系，例如显示显示器(LCD)的背光源不但可以用于为显示器提供背光以实现显示功能，而且背光源本身也可以作为良好的均匀面光源用于照明。因此，当前各种显示设备中的背光源的利用率不高。进一步地，当电视机的背光源亮度降到50％以下，已无法达到应有的显示效果时，尽管电视机中的其他组件可能仍然能够正常工作，但整个电视机将不得不被淘汰，因为背光源与电视机中其他组件通常是一体的，其中的组件是不易更换的。

具体实施方式
为了使本技术领域的人员更好地理解本公开方案，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述。
在本公开的说明书和权利要求书及上述附图中的描述的一些流程中，包含了按照特定顺序出现的多个操作，但是应该清楚了解，这些操作可以不按照其在本文中出现的顺序来执行或并行执行，操作的序号如101、102等，仅仅是用于区分开各个不同的操作，序号本身不代表任何的执行顺序。另外，这些流程可以包括更多或更少的操作，并且这些操作可以按顺序执行或并行执行。
图1和图2分别示出根据本公开一些和另一些实施例的显示面板的结构的正视图和侧视图。参照图1和图2，显示面板100、200包括显示模组101、201和背光模组102、202，显示模组101、201与背光模组102、202通过连接组件103、203可相对运动地连接以使背光模组102、202在第一状态与第二状态之间切换，其中在第一状态下，背光模组102、202被显示模组101、201遮挡，且在第二状态下，背光模组102、202被暴露。
如上所述，背光模组102、202的第一状态是指被显示模组101、201遮挡的状态(图中未示出)；如图1和图2所示，背光模组102、202的第二状态是指显示模组101、201与背光模组102、202相对错位而使背光模组102、101被暴露出来的状态。
在根据本公开一些实施例的显示面板中，通过在显示模组101、201与背光模组102、202之间引入连接组件(例如，图1所示的滑动机构103和图2所示的翻转结构203)，使得背光模组和显示模组二者可以相对于彼此移动而形成错位，从而将位于显示模组背后的背光模组暴露出来，这时背光模组可以利用其均匀面光源的特性实现照明功能。这样，根据本公开的显示面板利用在其显示模组和背光模组之间的可相对运动的连接方式，实现了背光模组和显示模组之间的自由错位和复位，从而使得该显示面板在具备传统的显示功能的基础上，还可以用作照明设备。与相关技术相比，本公开的这种多功能的显示面板可以更充分利用背光模组的照明功能，避免资源闲置和浪费；同时还可以避免了单独购置显示装置和照明装置，为用户节省了成本和空间。
在根据本公开一些实施例中，如图1和图2所示，连接组件103、203可以设置在显示模组101、201的边缘和背光模组102、202的边缘之间，以避免阻挡从背光模组102、202发射到显示模组101、201的背光，继而影响显示面板100的显示功能。可选地，连接组件103、203可以是滑动机构103(图1)或翻转机构203(图2)。换言之，显示模组101、201与背光模组102、202之间的相对运动可以通过滑动或转动方式实现。
一般地，上述“边缘”，对于矩形显示面板100、200而言，通常包括上边缘、下边缘、左侧边缘和右侧边缘。图1示出了滑动结构103设置在显示模组101与背光模组102的左右两侧边缘的情况，这时可 以实现显示模组101与背光模组102之间相对的上下滑动而错位；而图2示出了翻转机构203设置在显示模组201与背光模组202上部或顶部边缘之间的情形，这时也可以实现显示模组201与背光模组202之间相对的上下转动而错位。类似地，尽管图中未示出，图1中的滑动机构103也可以设置在上下(或顶部和底部)边缘处以实现显示模组101与背光模组102之间相对的左右滑动而错位，而图2中的翻转机构203也可以设置在底部边缘、左右两侧边缘处，从而实现显示模组201与背光模组202之间相对的左右转动而错位。
如图1所示，在根据本公开一些实施例中，滑动机构103可以包括彼此平行地设置在背光模组102和显示模组101左右两侧边缘之间的第一滑动器1031和第二滑动器1032。这样的双滑动器设置可以保证背光模组102和显示模组101之间的相对滑动过程中的平稳顺畅。此外，如上文所述，第一滑动器1031和第二滑动器1032也可以分别设置在背光模组102和显示模组101上下侧边缘之间。此外，在一些实施例中，第一滑动器1031和第二滑动器1032可以采用滚珠轴承滑动器或安装有辊子的滑动器。
在根据本公开的一些实施例中，如图1所示，滑动机构103中的第一滑动器1031可以包括可相对于彼此滑动连接的滑轨1031a和滑座1031b，其中滑轨1031a与显示模组101固接，而滑座1031b与背光模组102固接。需要说明的是，尽管图中没有示出，滑轨1031a也可以与背光模组102固接，同时滑座1031b与显示模组101固接。类似地，第二滑动器1032也可以包括滑轨和滑座，其中之一与显示模组101固接，而另一个与背光模组102固接，以实现显示模组101和背光模组102之间的相对滑动。
在根据本公开的一些实施例中，如图2所示，翻转机构203包括可相对于彼此翻转连接的支撑轴203a和轴套203b，其中支撑轴203a与背光模组202固接，而轴套203b与显示模组201固接，这样使显示模组201可绕支撑轴203a相对背光模组202翻转，令二者错位以使背光模组202暴露。另外，在一些实施例中，支撑轴203a和轴套203b也可以分别固接到显示模组201和背光模组202，以使背光模组202可绕支撑轴203a相对于显示模组201翻转，从而使二者错位而暴露背光模组202。
在根据本公开的一些实施例的显示面板100、200中，背光模组102、202与显示模组101、201可以配置成可拆卸地相互连接。这种可拆卸的连接方式有利于背光模组102、202和显示模组101、201的单独替换。例如，当背光模组102、202和显示模组101、201中只有一个损坏或老化时，可以方便地单独替换损坏的模组，而不必替换整个显示面板100、200，从而简化了替换流程，提高了工作效率和组件利用率，避免了资源浪费。进一步地，被替换下来的背光模组102、202也可能仅仅由于亮度降低而无法达到显示要求，而并未完全损坏，因此它还可以进行二次利用，例如用于浴室、走廊等地方的照明，这进一步提高了废物利用率。
在一些实施例中，显示面板100还可以包括用于防止背光模组102与显示模组101之间的间隙漏光的防漏光组件(未示出)。防漏光组件可以设置于背光模组102和显示模组101中至少一个的边缘。由于显示模组101与背光模组102之间特殊的可相对移动的连接组件103，因此显示模组101和背光模组102之间有可能存在间隙，防漏光组件104能够有效防止漏光，以提高显示效果。
可选地，显示面板100的防漏光组件104可以包括沿背光模组102和显示模组101中除了连接组件所在的边缘之外的边缘延伸的边框(未图示)，该边框与连接组件103(例如第一滑动器和第二滑动器)共同将背光模组102和显示模组101四周包围起来，用于防止背光模组102与显示模组101之间的间隙漏光。例如，当连接组件103包含如图1所示的第一和第二滑动器1031、1032且各滑动器包含滑轨1031a和滑座1031b时，该防漏光组件包括两条边框，其中一条边框可以固接于显示模组101设有用于收容背光模组102边缘的第一凹槽(未图示)，另一条边框可以固接于背光模组102设有用于收容显示模组101边缘的第二凹槽。可以理解的，当显示模组101和背光模组102未发生相对错位，背光模组102的一条边收容于第一凹槽，其余边被与其固接的边框和滑轨1031a包围；显示模组101的一条边收容于第二凹槽，其余边同样被与其固接的边框和滑轨1031a包围；当显示模组101和背光模组102发生相对错位，固接于可滑动的显示模组101和/或背光模组102的边框可随显示模组101和/或背光模组102滑动。
在如图1所示实施例中，滑轨1031a夹设于背光模组102的左右 两侧，滑座1031b可滑动地嵌套于滑轨1031a并与显示模组101固接；当仅有滑座1031b可沿滑轨1031a上下滑动，固接于显示模组101顶部或底部边缘的边框可随显示模组101上下滑动，固接于背光模组102底部或顶部(与显示模组1边缘的边框相对设置)边缘的边框不可移动；当滑座1031b和滑轨1031a可分别上下滑动，两条边框分别可随显示模组101和背光模组102上下滑动。
可选地，防漏光组件可以包括在显示模组101的入光面上沿其边缘延伸的密封条(未图示)以及在背光模组102的出光面上沿其边缘延伸的收容槽(未图示)。当背光模组102处于第一状态或显示面板100处于显示模式时，即显示模组101和背光模组102重叠而未发生相对错位时，密封条可以收容于收容槽，用于防止背光模组102与显示模组101之间的间隙漏光。
图3示意性示出根据本公开一些实施例的显示面板300的结构框图。如图3所示，除了显示模组301、背光模组302、连接组件303、防漏光组件304之外，显示面板300可以进一步包括驱动组件305，其配置成驱动连接组件303以使背光模组302与显示模组301相对运动。驱动组件305通过例如电动、液压、气压、电磁等方式来驱动连接组件303。因此取决于驱动方式，驱动组件305可以是驱动电路或其他类型的驱动装置。此外，驱动组件305可以设置在显示模组301中(例如与其液晶驱动电路集成在一起)或背光模组302中。当然，驱动组件305也可以独立于显示模组301和背光模组302而设置。当显示面板300或包括显示面板300的显示装置的面积、体积或重量较大时(例如当前的大尺寸液晶电视的面板)，人工控制连接组件303实现滑动或翻转可能比较困难，甚至无法实现。驱动组件305的引入可以实现背光模组302和显示模组301之间的相对运动的自动化和非接触式控制，增强了产品使用的便利性和工作效率，提高了用户体验。
在根据本公开的一些实施例，如图3所示，显示面板300还可以包括控制组件306，其配置成接收控制信号并根据控制信号控制驱动组件305、背光模组302和显示模组301中至少一个。控制组件306例如可以集成在显示模组301中，并且与背光模组302和驱动组件305电性连接以用于对其进行控制。控制组件306可以具备信号接收功能(例如内含信号接收器)和处理功能，例如可以从信号源(例如红外遥控 器)接收用户输入的控制信号，从而根据控制信号控制驱动组件305、显示模组301和背光模组302中至少一个，以自动实现背光模组302和显示模组301的相对运动，从而使背光模组302可以在第一状态(即显示模式)和第二状态(即照明模式)之间自由切换，改善用户操作的便利性。此外，控制组件306也可以根据其他控制信号控制其他组件，例如背光模组302或显示模组301，以实现相应操作。控制组件306可以包括中央处理单元(CPU)、只读存储器(ROM)，用于存储由CPU执行的程序和在这些程序中所用的数据；随机存取存储器(RAM)，用于暂时存储在执行这些程序中所用的数据。这些组成部件协同操作以完成控制组件的功能。将理解的是，这些功能可以由软件、硬件或其组合实现。
在根据本公开的一些实施例，控制信号可以包括第一控制信号和第二控制信号，其分别对应于背光模组302的第一状态和第二状态，即显示模式和照明模式。例如，用于包括根据本公开的显示面板300的显示装置的遥控器中可以包括两个按钮，分别为“显示模式”和“照明模式”。用户可以通过选择这两种模式来向显示装置或显示面板发送第一控制信号和第二控制信号。相应地，显示面板中的控制组件306可以进一步配置成响应于第一控制信号控制驱动组件305以使背光模组302处于第一状态，且响应于第二控制信号控制驱动组件305以使背光模组302处于第二状态。
在根据本公开的一些实施例，如图3所示，显示面板300还可以包括监测组件307，其配置成监测从背光模组302发射的背光的亮度和环境光的亮度中至少一个。相应地，控制组件306可以配置成根据所监测的背光亮度和环境光亮度中至少一个，控制显示面板300中的其他构件，例如可以在背光模组302处于第一状态或“显示模式”时根据背光亮度判断背光模组302是否达到显示要求(从而确定背光模组302到达显示寿命终点)，或者在背光模组302处于第二状态或“照明模式”时根据环境光亮度调整背光亮度，以适应环境变化。例如，在判断背光亮度是否满足现实要求时，可以预先设定一个亮度阈值，该亮度阈值可以根据显示面板的结构、功能或背光模组的原始亮度等进行设定。一般地，可以将亮度阈值设定为原始背光亮度的50％，即当背光模组302老化以致其背光亮度衰减到初始亮度的一半以下时，可 以判定该背光模组无法满足显示要求，需要考虑更换。
在一些实施例中，控制组件306还可以配置成响应于背光模组302处于第二状态，根据从用户接收的控制信号来调节背光亮度或者根据预定规则调节背光亮度。预定规则可以是系统默认设定或用户设定并存储的规则。可选地，用户可以根据时间设定的规则，如8时到17时设定为第一亮度，18时到0时设定为第二亮度，0时到8时设定为第三亮度。
在根据本公开的一些实施例中，如图3所示，监测组件307可以包括设置在背光模组302的出光面上用于监测背光亮度的第一亮度传感器307a，并且也可以包括设置在背光模组302的非出光面用于监测环境光的第二亮度传感器307b。背光模组302的非出光面可以包括与出光面相对的表面以及或背光模组302的侧面。这样设置的目的在于尽可能降低或避免第一亮度传感器307a和第二亮度传感器307b对背光的阻挡和不良影响。
可选地，为了更精确地测量背光模组302的背光亮度，避免因样本过少造成以偏概全的错误判断，可以在背光模组302的出光面上布置多个第一亮度传感器307a以感测相应局部的背光亮度，从而实现背光模组302的整体发光性能的确切判断。例如，为了避免阻挡或影响背光对显示模组301的照射，可以在背光模组302的出光面的角落处布置多个第一亮度传感器307a以感测背光模组发射的背光的亮度。一般地，显示面板或其中的背光模组302为矩形形状，因此通常可以在四个(例如左上、右上、左下、右下)角落处布置四个第一亮度传感器307a。当然，对于其他形状的显示面板300或背光模组302，可以根据其特定形状布置相应数量的第一传感器307a。
相应地，当监测组件307包括多个第一传感器307a时，控制组件306可以配置成：响应于背光模组处于第一状态，将多个第一亮度传感器感测的多个背光亮度分别与亮度阈值进行比较；在所述多个背光亮度中至少两个低于亮度阈值的情况下，控制显示模组显示更换背光模组的提示信息；以及在所述多个背光亮度中只有一个低于亮度阈值的情况下，控制显示模组进行背光补偿。如上文所述，亮度阈值可以根据背光模组的原始亮度和显示面板的整体结构和功能等因素来设定，例如可以设定为原始亮度的50％，例如可以是背光模组302的额定发 光流明的50％或其他根据用户设定的流明值。为了更充分地利用背光模组302，避免因个别的局部亮度衰减而替换整个模组，可以在处于角落处的四个第一亮度传感器307a所感测的亮度值中存在两个以上的背光亮度感测值低于阈值(例如原始亮度的50％)的情况下，判定其无法满足现实要求，从而建议替换，例如可以控制显示模组301显示例如“建议更换背光模组”的提示信息。而当仅有一个亮度感测值小于阈值时，仅表示相应局部的亮度无法达到显示要求(其他局部亮度正常)，因此可以认为就整体而言，显示模组301尚可继续使用，可以暂时不建议更换整个背光模组302，但是需要对亮度较低的局部进行适当处理以满足显示要求。可选地，可以通过调制显示模组301中液晶分子的偏转角度来使被亮度较低背光照射的显示模组301局部通过更多的背光来进行背光补偿。
在一些实施例中，为了实现显示面板300中的可拆卸连接，显示面板300中的显示模组301和背光模组302、驱动组件305、控制组件306、监测组件307之间的连接可以通过排线方式或直接卡槽接触方式实现，例如金手指、磁吸接头或其他触点式接头中的任意一种。
本公开还提供一种包括根据本公开一些实施例的显示面板的显示装置。
图4示意性示出根据本公开一些实施例的用于根据本公开一些实施例的显示面板的控制方法的流程图。如图4所示，用于根据本公开一些实施例的显示面板的控制方法包括以下步骤：
S410，接收控制信号；以及
S420，根据控制信号，控制连接组件以使背光模组可在第一状态与第二状态之间切换。
在图4所示的用于控制面板的控制方法中，控制信号可以是用户利用诸如遥控器之类的信号源向显示面板或包括显示面板的显示装置(例如电视机等)发送的信号，例如红外信号。控制面板在接收到控制信号之后可以根据控制信号来控制背光模组与显示模组之间的相对运动，实现背光模组在第一状态(即显示模式)和第二状态(即照明模式)之间切换。这样就实现了根据用户控制命令对背光模组的显示功能和照明功能进行自动选择和切换。具体实施方式可参照上文关于根据本公开一些实施例的显示面板的描述。
图5示意性示出根据本公开另一些实施例的用于显示面板的控制方法的流程图。如图4所示的步骤S420中的控制信号可以包括第一控制信号和第二控制信号，其例如分别对应于背光模组的第一状态和第二状态。因此，在图5所示的控制方法中，步骤S510与图4中S410相同，而图4中的步骤S420-根据控制信号控制连接组件以使背光模组可在第一状态与第二状态之间切换包括：
S521，判定接收的控制信号为第一控制信号还是第二控制信号；
S522，响应于第一控制信号，控制连接组件以使背光模组处于第一状态；以及
S523，响应于第二控制信号，控制连接组件以使背光模组处于第二状态。
在根据本公开的一些实施例中，如图5所示，图5所示的用于显示面板的控制方法进一步包括如下步骤：
S530，响应于背光模组处于第一状态，分别在背光模组发光面的多个角落处感测背光模组发射的背光亮度；
S540，将在多个角落处感测的所述多个背光亮度分别与阈值亮度进行比较；
S550，在所述多个背光亮度都高于亮度阈值的情况下，可以返回步骤S530；
S560，在所述多个背光亮度中至少两个低于亮度阈值的情况下，控制显示模组显示更换背光模组的提示信息；以及
S570，在所述多个背光亮度中只有一个低于亮度阈值的情况下，控制显示模组进行背光补偿。
在根据本公开的一些实施例中，如图6所示，图5所示的用于显示面板的控制方法还可以进一步包括如下步骤：
S580，响应于背光模组处于第二状态，感测环境光亮度；以及
S590，根据环境光亮度调节背光的亮度。
