Description

双面显示器、显示装置、汽车及交互方法 技术领域
本申请涉及显示技术领域，尤其涉及一种双面显示器、显示装置、汽车及交互方法。
背景技术
随着科技的发展，显示设备在当前的电子设备中占有越来越重要的角色。当前的显示设备通常具有发光面和背离发光面的背面，发光面能够显示图像、文字等信息，而背面则无法进行显示，即显示设备只能够单面显示。随着显示技术的发展，越来越多的场合需要具备更多显示功能的显示设备。
发明内容
本申请提供了一种双面显示器、显示装置、汽车及交互方法，用于提供一种具备透明显示功能的双面显示器。
第一方面，本申请提供的一种双面显示器，包括：相对设置的第一透明显示面板和第二透明显示面板，以及位于所述第一透明显示面板和所述第二透明显示面板之间的调光层；所述调光层用于根据加载的电压呈透光态或遮光态。因此，当调光层呈遮光态时，不仅可以使双面显示器起遮光作用，还可以避免第一透明显示面板和第二透明显示面板同时进行显示时彼此影响。当调光层呈透光态时，光可以从第一透明显示面板和第二透明显示面板的透光区透过，从而可以实现透明功能。
示例性的，本申请实施例提供的双面显示器的显示模式可以包括非透明显示模式和透明显示模式。当所述双面显示器处于所述非透明显示模式时，所述调光层根据加载的电压呈现遮光态，所述第一透明显示面板和所述第二透明显示面板可以分别根据各自加载的显示信息进行显示；当所述双面显示器处于所述透明显示模式时，所述调光层根据加载的电压呈现透光态，所述第一透明显示面板和所述第二透明显示面板分别根据各自加载的显示信息进行显示。
在本申请中，第一透明显示面板的透光区域与第二透明显示面板的透光区域需要存在重叠区域，双面显示器才能够透光，因此，在第一透明显示面板的透光区域与第二透明显示面板的透光区域的面积固定的基础上，第一透明显示面板的透光区域与第二透明显示面板的透光区域的重叠区域的面积越大，双面显示器的透光面积越大。
可选的，在本申请中，可以是第一透明显示面板的透光区域覆盖第二透明显示面板的透光区域，或者，也可以是第二透明显示面板的透光区域覆盖第一透明显示面板的透光区域。
进一步地，当第一透明显示面板的透光区域与第二透明显示面板的透光区域完全重叠时，可以保证双面显示器在双侧显示面积一致的情况下透光面积最大。
示例性的，调光层可以采用电致变色材料或者液晶显示面板等任何根据加载的电压能够实现透光态或遮光态功能的结构形成，在此不作限定。

实施例一、
示例性的，如图1所示，本申请一种实施例提供的双面显示器10包括：相对设置的第一透明显示面板11和第二透明显示面板12，以及位于所述第一透明显示面板11和所述第二透明显示面板12之间的调光层13；所述调光层13用于根据加载的电压呈透光态或遮光态。
在具体实施时，透明显示面板是指显示面板的显示区域中存在透光区域，在显示面板在不显示画面时，观察者可以通过透光区域从显示面板前方看到显示面板后方的环境场景，当显示面板显示画面时，位于显示区域内的透光区域依然可以呈现透明状态。
本申请中，所述第一透明显示面板11和所述第二透明显示面板12可以是任何可以实现透明显示功能的显示面板，例如现有的液晶(Liquid Crystal，LC)透明显示面板或发光二极管(Light-emitting diode，LED)透明显示面板等，在此不作限定。
在本申请中，当调光层13呈遮光态时，不仅可以使双面显示器10起遮光作用，还可以避免第一透明显示面板11和第二透明显示面板12同时进行显示时彼此影响。当调光层13呈透光态时，光可以从第一透明显示面板11和第二透明显示面板12的透光区透过，从而可以实现透明功能。
示例性的，本申请实施例提供的双面显示器10的显示模式可以包括非透明显示模式和透明显示模式。
当所述双面显示器10处于所述非透明显示模式时，所述调光层13根据加载的电压呈现遮光态，所述第一透明显示面板11和所述第二透明显示面板12可以分别根据各自加载的显示信息进行显示；
当所述双面显示器10处于所述透明显示模式时，所述调光层13根据加载的电压呈现透光态，所述第一透明显示面板11和所述第二透明显示面板12分别根据各自加载的显示信息进行显示。
本申请中，第一透明显示面板和第二透明显示面板的显示是彼此独立的，即第一透明显示面板可以根据需求在任何时间根据加载在第一透明显示面板的显示信息进行显示，第二透明显示面板同样可以根据需求在任何时间根据加载在第二透明显示面板的显示信息进行显示。而第一透明显示面板的显示画面和第二透明显示面板的显示画面可以是相同的，也可以是不同的，在此不作限定。
在本申请中，第一透明显示面板11的透光区域与第二透明显示面板12的透光区域需要存在重叠区域，双面显示器10才能够透光，因此，在第一透明显示面板11的透光区域与第二透明显示面板12的透光区域的面积固定的基础上，第一透明显示面板11的透光区域与第二透明显示面板12的透光区域的重叠区域的面积越大，双面显示器10的透光面积越大。
可选的，在本申请中，可以是第一透明显示面板11的透光区域覆盖第二透明显示面板12的透光区域，或者，也可以是第二透明显示面板12的透光区域覆盖第一透明显示面板11的透光区域。
进一步地，当第一透明显示面板11的透光区域与第二透明显示面板12的透光区域完全重叠时，可以保证双面显示器10在双侧显示面积一致的情况下透光面积最大。
示例性的，调光层可以采用电致变色材料或者液晶显示面板等任何根据加载的电压能够实现透光态或遮光态功能的结构形成，在此不作限定。
在一种实施例中，所述调光层可包括液晶显示面板。液晶显示面板可以根据加载的电压对透光程度进行不同程度的控制，从而可以呈现由完全透光至完全遮光之间的不同灰阶度，以255灰阶液晶显示面板为例，液晶显示面板可以呈从0至255灰阶的256阶透光程度，从而可以实现显示背景的多元化。
在具体实施时，本申请中液晶显示面板可以为黑白液晶显示面板，即液晶显示面板中不设置彩色光阻层。
示例性的，如图2所示，液晶显示面板130主要包括：相对设置的第一透明基板131和第二透明基板132，位于所述第一透明基板131和所述第二透明基板132之间的液晶层133，分别位于所述液晶层133两侧的第一偏光片134和第二偏光片135，以及位于所述第一透明基板131和所述第二透明基板132之间的第一透明电极136和第二透明电极137；所述第一偏光片134的偏振方向和所述第二偏光片135的偏振方向垂直；所述液晶显示面板用于根据加载在所述第一透明电极131和所述第二透明电极132上的电压呈透光态或遮光态。
液晶显示面板的工作原理为：加载在所述第一透明电极131和所述第二透明电极132上的电压可以产生电场，电场控制液晶层133中液晶分子的偏转，所述第一透明电极131和所述第二透明电极132之间的电压差不同，导致电场强度不同，从而液晶分子的偏转角度不同，进而使液晶显示面板的透光程度不同。
本申请中，液晶显示面板130可以为常黑态液晶显示面板，即液晶显示面板130在不加载电压时呈遮光态，当然液晶显示面板130也可以常白态液晶显示面板，即液晶显示面板130在不加载电压时呈透光态，在此不作限定。
在具体实施时，第一偏光片134一般设置在第一透明基板131背离液晶层133一侧，第二偏光片135一般设置在第二透明基板背离液晶层133一侧。第一透明电极131和第二透明电极132可以设置在液晶层133的两侧，当然也可以设置在液晶层133的同一侧，在此不作限定。
进一步地，在本申请中，双面显示器中还可以包括光传感器，利用光传感器检测环境光的强度，液晶显示面板可以根据光传感器检测的环境光的强度控制透光程度，例如光传感器检测的环境光的强度越强，液晶显示面板的透光程度越小。
在具体实施时，由于LED显示面板相比液晶显示面板具有自发光、结构简单、超轻薄、响应速度快、宽视角、低功耗等特性，因此，在一种实施例中，第一透明显示面板和第二透明显示均可以设置为LED透明显示面板。
示例性的，如图2所示，第一透明显示面板11可以包括相对设置的第三透明基板111和第四透明基板112，位于所述第三透明基板111和所述第四透明基板112之间的多个第一像素pix1；所述多个第一像素pix1中至少部分相邻所述第一像素pix1之间具有透光区域s1；其中，每一所述第一像素pix1包括至少一个发光二极管(图2中未视出)以及用于驱动所述发光二极管发光的像素电路(图2中未视出)。
