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、完整的描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别 类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的电子设备的盖板进行详细地说明。
如图1至图4所示，本申请实施例公开一种电子设备的盖板，可选地，该盖板可以是电子设备的后盖，也可以是覆盖于电子设备的显示屏上的透光盖板。本申请实施例公开的盖板包括依次叠置的第一基板110、第一电极层120、电致变色层130、第二电极层140和第二基板150。可选地，第一基板110和第二基板150均可以是玻璃等透明材料制成的结构，第一电极层120和第二电极层140可以是氧化铟锡等金属材料制成的结构，电致变色层130的光学属性(例如反射率、透过率、吸收率等)在外加电场的作用下可以发生稳定、可逆的变化，从而改变电致变色层130的颜色。第一电极层120和第二电极层140可以设置第一平坦化层，该第一平坦化层可以采用树脂等材料制成，其厚度可以是1.5～3um，覆盖第二电极层140的第二平坦化层可以采用低介电常数的树脂等材料制成，其厚度可以是1.5～3um，第二平坦化层的上方可以设置保护层，该保护层可以采用环境依赖性以及静电防护效果均较佳的材料制成，其厚度可以是3～50um，从而既保证保护效果，又不对指纹识别的准确度和效率产生负面影响。
在盖板处于第一时间段的情况下，第一电极层120和第二电极层140之间形成第一电压差，电致变色层130在第一电压差的作用下发生氧化还原反应，从而发生颜色变化，进而实现变色显示的功能。在盖板处于第二时间段的情况下，第一电极层120和第二电极层140之间形成脉冲电压差，第一电 极层120和第二电极层140在脉冲电压差的作用下组成指纹识别结构，从而实现指纹识别功能。当第一电极层120和第二电极层140组成指纹识别结构时，电致变色层130可以作为第一电极层120和第二电极层140之间的介电层，用户的指纹具有指纹脊510和指纹谷520，指纹脊510与盖板中位于第二电极层140所在位置处的表面紧密接触不留空隙，而指纹谷520与该表面之间存在空气间隙，因此指纹谷520和指纹脊510与盖板表面存在接触差异，当检测盖板各处的第一电极层120和第二电极层140之间的电容时，指纹谷520和指纹脊510对应的第一电极层120和第二电极层140之间的电容不同，经过对电容信号的处理，可以得到指纹图像。
盖板具有触控表面，指纹识别结构对应触控表面设置，这里的触控表面可以是盖板背离显示屏的表面，该表面可以设置摄像头模组400等结构；触控表面也可以是盖板的与显示屏同侧设置的表面；触控表面还可以是盖板的侧面。第二电极层140可以位于第一电极层120朝向触控表面的一侧，即，第二电极层140位于第一电极层120和触控表面之间，第二电极层140距离触控表面更近。组成指纹识别结构的第二电极层140可以包括多个呈阵列排布的感应像素单元141，在盖板处于第二时间段的情况下，不同的感应像素单元141用于感应触控表面的不同区域的信号变化，从而实现指纹识别，即，不同的感应像素单元141所感应到的信号变化可与用户的指纹脊510和指纹谷520相对应，从而进行指纹识别。
可选地，为了使盖板在不同时间段下实现不同的功能，可以对盖板进行分时控制。参考图6，在第一时间段T1内，电致变色层130处于工作状态，此时可以对第一电极层120和第二电极层140的电压进行控制，从而控制第一电极层120和第二电极层140之间所形成的电压差，使得电致变色层130产生不同的颜色，从而实现变色显示；在第二时间段T2内，第一电极层120和第二电极层140所组成的指纹识别结构可以利用识别过程中自身所产生的电容变化来识别用户的指纹信息，此时电致变色层130不工作，第一电极层 120和第二电极层140之间形成脉冲电压差，第二电极层140可以感应电容信号的变化，从而得到用户的指纹信息。
需要说明的是，上述第一时间段指的是盖板进行变色显示的时间段，此时间段下，不需要进行指纹识别；第二时间段则指的是需要进行指纹识别的时间段，此时，盖板不进行变色显示。当然，盖板也可以在变色显示的同时实现指纹识别，此时，第一电极层120和第二电极层140之间既可以形成第一电压差，又同时形成脉冲电压差。
在本申请实施例中，第一电极层120和第二电极层140可以驱动电致变色层130变色，从而实现盖板的变色显示，与此同时，第一电极层120和第二电极层140可以在脉冲电压差的作用下组成指纹识别结构，当用户的手指放置在盖板的目标区域时，该指纹识别结构可以识别用户的指纹信息，从而实现指纹识别功能。可见，本申请实施例公开的盖板可以通过结构复用同时实现变色显示和指纹识别功能，从而不需要在电子设备中额外设置指纹识别模组，因而可以简化电子设备的结构。
可选的实施例中，在盖板处于第二时间段的情况下，第一电极层120加载脉冲电压，以使第一电极层120与第二电极层140之间形成脉冲电压差。由于第二电极层140更靠近触控表面，因此在第一电极层120加载脉冲电压，可以使第二电极层140更精确地感应信号变化，从而更灵敏地实现指纹识别。
可选地，盖板还包括驱动部，第一基板110设有多个呈阵列排布的驱动单元200，驱动部通过各驱动单元200与各感应像素单元141电连接，且驱动部与第一电极层120电连接。此时，驱动部可以通过各驱动单元分别控制多个感应像素单元141的状态，从而以更高的精度识别指纹信息。可选地，为了提升指纹识别的精度，第一电极层120和第二电极层140的像素间距可以设置为50～100um。
可选的实施例中，盖板具有第一区域101和第二区域102，第一区域101位于第二区域102之外，也就是说，第一区域101与第二区域102不重叠。 在盖板处于第二时间段的情况下，位于第一区域101内的感应像素单元141和第一电极层120位于第一区域101内的部分在脉冲电压差的作用下组成指纹识别结构。此时，盖板的局部区域形成指纹识别结构，从而实现该局部区域的指纹识别操作，而其他不需要识别指纹信息的区域则不参与指纹识别过程，从而降低盖板的控制成本。
如前所述，盖板可以为电子设备的后盖，进一步可选地，后盖包括主体部以及设置于主体部的边缘的环形侧部，主体部和环形侧部中的至少一者设有第一区域101，也就是说，可以仅在主体部或环形侧部设有第一区域101，也可以同时在主体部和环形侧部设有第一区域101。当主体部设有第一区域101时，用户可以将手指放置在后盖背离显示屏的一面，进而实施指纹识别操作，该面不经常被用户看到，因此这样设置可以获得更好的外观质感；当环形侧部设有第一区域101时，用户可以将手指(Finger)放置在后盖的侧面，进而实施指纹识别操作，由于环形侧部常常被用户握持，因此该面设置第一区域101更便于用户实施指纹识别操作。
前文描述了仅在第一区域101内识别指纹信息的方案，其他实施例中，也可以使盖板的整面都能识别指纹信息。即，在盖板处于第二时间段的情况下，所有的感应像素单元141和第一电极层120在脉冲电压差的作用下组成指纹识别结构。该方案不限制用户实施指纹识别操作的位置，因此更便于用户实施指纹识别操作。
一种可选的实施例中，在盖板处于第二时间段的情况下，第一电极层120为驱动信号发射端，感应像素单元141为驱动信号接收端。此实施例中，在垂直于盖板的方向上，第一电极层120的正投影和第二电极层140的正投影可以互不重叠，也可以部分重叠，第一电极层120和第二电极层140可以形成互容式指纹识别结构，此结构具有更便于实施多点指纹识别以及识别速度较快等优点。
另一种可选的实施例中，在盖板处于第二时间段的情况下，不同的感应 像素单元141用于感应触控表面的不同区域之间的电容差值。此种设置方式可以实现自电容式指纹识别结构，此结构具有结构简单、计算量小等优点。
为了更好地控制指纹识别结构和电致变色层130的工作状态，可选地，参考图8，驱动单元200包括第一复位晶体管210、第一增益晶体管220和第一读取晶体管230，驱动部设有第一驱动端310(即VDR端)、第二驱动端320(即VDD端)、读取端330(即Read端)、复位端340(即Vreset端)和栅极信号端350(即Vgate端)。第一复位晶体管210的源极与第一驱动端310电连接，第一复位晶体管210的漏极与感应像素单元141电连接，第一复位晶体管210的栅极与复位端340电连接。第一增益晶体管220的源极与第二驱动端320电连接，第一增益晶体管220的漏极与第一读取晶体管230的源极电连接，第一增益晶体管220的栅极与感应像素单元141电连接，第一读取晶体管230的漏极与读取端330电连接，第一读取晶体管230的栅极与栅极信号端350电连接。此种驱动单元200为有源驱动结构，第一复位晶体管210可以实现复位，复位方式可以选择帧复位以及行复位两种方案，第一增益晶体管220对电容信号进行有源增益，第一读取晶体管230可以控制电容信号(Signal)的读取。如图7所示，t1复位时刻，Vreset端为高电平，Vgate端低电平，第一读取晶体管230关闭，第一复位晶体管210打开，VDR端给第二电极层140加载固定复位信号；t2采样时刻，第一读取晶体管230和第一复位晶体管210均关断，第二电极层140因手指感触发生电荷转移，电压值发生变化；t3读取时刻，Vreset端为低电平，Vgate端高电平，第一复位晶体管210关断，第一读取晶体管230开启，Read端读取第二电极层140反馈的信号，并且每一行依次打开进行信号读取。
参考图4所示，驱动单元200设置于第一基板110，第一基板110上依次设置栅极绝缘层181、层间介电层182、第一绝缘层183、第二绝缘层184和第三绝缘层185，其中：栅极绝缘层181可覆盖驱动单元200的源极和漏极之间的多晶硅；层间介电层182可覆盖驱动单元200的栅极；第一绝缘层 183可以设置于第一电极层120与驱动单元200的源极和漏极之间；第二绝缘层184可以隔开第一电极层120和第二电极层140；第三绝缘层185可覆盖第二电极层140。
另一可选的实施例中，如图9所示，驱动单元200包括第二复位晶体管240、第二增益晶体管250和第二读取晶体管260，驱动部设有第一驱动端310(即VDR端)、第二驱动端320(即VDD端)、读取端330(即Read端)和栅极信号端350(即Vreset N端)。第二复位晶体管240的源极与第一驱动端310电连接，第二复位晶体管240的漏极与感应像素单元141电连接；第二增益晶体管250的源极与第二驱动端320电连接，第二增益晶体管250的漏极与第二读取晶体管260的源极电连接，第二增益晶体管250的栅极与感应像素单元141电连接，第二读取晶体管260的漏极与读取端330电连接，第二读取晶体管260的栅极以及第二复位晶体管240的栅极均与栅极信号端350电连接。此实施例中，第二复位晶体管240可以采用PMOS(P-channel metal oxide semiconductor，P沟道金属氧化物半导体)驱动，其栅极和第二读取晶体管260的栅极均由Vgate信号线控制，从而在Vgate为低电平时刻，第二复位晶体管240打开，实现复位功能，Vgate为高电平时刻，第二复位晶体管240关闭，第二读取晶体管260打开，实现信号的读取。该实施例可以实现读取信号与复位信号整合，以简化驱动设计。
再一种可选的实施例中，如图10所示，驱动单元200包括第三复位晶体管270、第三增益晶体管280和第三读取晶体管290，驱动部设有第一驱动端310(即VDR端)、第二驱动端320(即VDD端)、读取端330(即Read端)和栅极信号端350(即Vgate N端)。第三复位晶体管270的源极与第一驱动端310电连接，第三复位晶体管270的漏极与感应像素单元141电连接，第三复位晶体管270的栅极信号由栅极信号端350的上一级信号提供；第三增益晶体管280的源极与第二驱动端320电连接，第三增益晶体管280的漏极与第三读取晶体管290的源极电连接，第三增益晶体管280的栅极与所述感 应像素单元(141)电连接，第三读取晶体管290的漏极与读取端330电连接，第三读取晶体管290的栅极与栅极信号端350电连接。此实施例的区别在于，Vreset信号由上一级Vgate信号提供，从而实现读取信号与复位信号整合，以简化驱动设计。
为了匹配更优的指纹脊510与指纹谷520的差异率，可以将感应像素单元141设置为菱形单元(如图5所示)或者条状单元。当然，感应像素单元141还可以设置为矩形单元或者其他形状的结构，本申请实施例对此不作限制。
可选的实施例中，盖板还包括电解质层160和离子储存层170，电解质层160设置于电致变色层130与离子储存层170之间，离子储存层170设置于第一电极层120与电解质层160之间。电解质层160可以由导电材料制成，其可以提供电致变色层130所需的补偿离子，而离子储存层170可以在电致变色层130发生氧化还原反应时起到储存相应的反离子的作用，从而使得整个盖板达到电荷平衡的状态。
电致变色层130可以仅设置一层，也可以设置为至少两层，至少两层电致变色层130的变色参数不同，可选地，该至少两层电致变色层130可以产生不同的颜色。相对而言，后一实施例可以使得各电致变色层130之间产生颜色叠加或颜色互补的效果，从而带来更多的变色显示效果。
本申请实施例还公开一种电子设备，其包括上述任一实施例所述的盖板。
本申请实施例还公开一种电子设备的控制方法，该控制方法应用于上述电子设备，其包括：
S100、接收输入。这里的输入具体可以是用户输入，用户可以通过对显示屏实施触控操作执行目标输入操作，该目标输入操作可以对应用户希望电子设备所实现的功能。
S200、当输入为第一输入时，控制第一电极层120和第二电极层140之间形成第一电压差，电致变色层130在第一电压差的作用下发生颜色变化。 也就是说，第一输入为需要进行变色显示的输入。
S300、当输入为第二输入时，控制第一电极层120和第二电极层140之间形成脉冲电压差，第一电极层120和第二电极层140在脉冲电压差的作用下组成指纹识别结构，通过第二电极层140的不同的感应像素单元141感应触控表面的不同区域的信号变化，以获取指纹信息。也就是说，第二输入为需要进行指纹识别操作的输入。
采用上述控制方法时，可以通过第一电极层120和第二电极层140同时实现变色显示功能和指纹识别功能，从而不需要在电子设备中额外设置指纹识别模组，因而可以简化电子设备的结构。
可选地，上述步骤S300中的控制第一电极层120和第二电极层140之间形成脉冲电压差，具体为：向第一电极层120加载脉冲电压，以使第一电极层120和第二电极层140之间形成脉冲电压差。由于第二电极层140更靠近触控表面，因此在第一电极层120加载脉冲电压，可以使第二电极层140更精确地感应信号变化，从而更灵敏地实现指纹识别。
可选地，上述步骤S200中的控制第一电极层120和第二电极层140之间形成第一电压差，具体为：向第一电极层120加载低电平信号，向第二电极层140加载高电平信号，从而在第一电极层120和第二电极层140之间形成第一电压差；上述步骤S300中的控制第一电极层120和第二电极层140之间形成脉冲电压差，具体为：向第一电极层120加载脉冲信号，向第二电极层140加载高电平信号，从而在第一电极层120和第二电极层140之间形成脉冲电压差。此实施例中，无论在第一时间段还是第二时间段，第二电极层140加载的都是高电平信号，从而简化该控制方法。
本申请实施例还公开一种电子设备的控制装置，该控制装置应用上述控制方法，该控制装置包括接收模块和控制模块，其中：接收模块用于接收输入；控制模块用于在输入为第一输入时，控制第一电极层120和第二电极层140之间形成第一电压差，以使电致变色层130在第一电压差的作用下发生 颜色变化，并在输入为第二输入时，控制第一电极层120和第二电极层140之间形成脉冲电压差，以使第一电极层120和第二电极层140在脉冲电压差的作用下组成指纹识别结构，并通过第二电极层140的不同的感应像素单元141感应触控表面的不同区域的信号变化，以获取指纹信息。
