Abstract

本申请实施例公开了一种终端，该终端包括外壳、前屏、电路板和电源。前屏设置在外壳上，电路板和电源均设置在外壳内，电源与电路板电连接。前屏包括依次叠放的强化玻璃、变色层和显示屏，变色层与电路板电连接，变色层用于在接收到电路板的供电时变色。在前屏内设置了变色层，而且该变色层可以在接收到电路板的供电时变色。由于变色层仅用于变色，无法显示复杂的图像，变色层的耗电量远低于显示屏的耗电量，所以本申请实施例提供的终端可以在消耗较少电量的情况下，使得终端的前屏显示某种颜色。

Description

一种终端
本申请要求于2019年3月20日提交中国专利局、申请号为201920353704.5、发明名称为“一种终端”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
本申请实施例涉及终端技术领域，更具体的说，涉及终端。
背景技术
目前，随着技术的发展，越来越多的终端上设置有前屏，例如，智能手机、平板电脑、笔记本电脑、智能电视和智能手表等终端均设置有前屏。终端的外部结构主要包括外壳和设置在该外壳上的前屏，从外观一致性的角度考虑，设计出前屏的颜色与外壳的颜色相同的终端已成为未来的发展方向之一。
在不考虑耗电量的情况下，利用当前的技术可以实现前屏的颜色与外壳的颜色相同。例如，假设终端的外壳为红色，在终端处于待机状态时，终端的处理器可以向前屏发送控制指令，该控制指令用于指示前屏显示红色。在前屏接收到该控制指令时，前屏会显示红色。
上述技术方案在终端处于待机状态时，需要前屏始终处于运行状态并显示目标颜色，以使前屏的颜色与外壳的颜色保持一致。但是，上述技术方案会使得前屏在终端处于待机状态下消耗大量的电能，从而缩短了终端的使用时长。
发明内容
本申请实施例提供一种终端，在消耗较少电量的情况下，使得终端的前屏显示目标颜色。
本申请实施例是这样实现的：
第一方面，本申请实施例提供了一种终端，该终端包括外壳、前屏、电路板和电源。前屏设置在外壳上，电路板和电源均设置在外壳内，电源与电路板电连接。前屏包括依次叠放的强化玻璃、变色层和显示屏，变色层与电路板电连接，变色层用于在接收到电路板的供电时变色。
在第一方面中，在前屏内设置了变色层，而且该变色层可以在接收到电路板的供电时变色。由于变色层仅用于变色，无法显示复杂的图像，变色层的耗电量远低于显示屏的耗电量，所以本申请实施例提供的终端可以在消耗较少电量的情况下，使得终端的前屏显示目标颜色。
在一种可能的实现方式中，变色层为电致变色组合层；电致变色组合层包括依次叠放的第一透明导电层、离子存储层、离子导体层、电致变色层和第二透明导电层；第一透明导电层和第二透明导电层均与电路板电连接。
其中，电致变色层的初始状态为透明状态，在第一透明导电层接收到电压时，离子存储层内存储的第一电离子经过离子导体层进入电致变色层。在电致变色层接收到第一电离子时，电致变色层由透明状态转换为目标颜色。在电致变色层为目标颜色且第一透明导电层未接收到电压时，电致变色层会维持在目标颜色。在电致变色层为目标颜色且第二透明导电层接收到电压时，电致变色层内的第一电离子会经过离子导体 层回到离子存储层，电致变色层会由目标颜色转换为透明状态。在电致变色层为透明状态且第一透明导电层和第二透明导电层均未接收到电压时，电致变色层会维持在透明状态下。通过电致变色组合层的工作原理可知，电致变色层可以在消耗较少电量的情况下显示目标颜色，而且，电致变色层还可以在消耗较少电量的情况下恢复至透明状态。
在一种可能的实现方式中，前屏还包括二氧化硅层、光学胶层和触感控制板；电致变色组合层的第一透明导电层固定在强化玻璃上；二氧化硅层的第一表面固定在电致变色组合层的第二透明导电层上；二氧化硅层的第二表面与显示屏的第一表面通过光学胶层粘接；显示屏的第二表面与触感控制板相贴合。
其中，二氧化硅层可以起到绝缘的作用，在电致变色组合层上加电压时，二氧化硅层可以避免电致变色组合层上的电流进入显示屏和触感控制板。而且，二氧化硅层与光学胶层具有更好的粘接性能。
在一种可能的实现方式中，电致变色组合层的厚度小于或等于10微米。
其中，为了避免前屏整体的厚度太大，可以将电致变色组合层的厚度控制在10微米以内。
在一种可能的实现方式中，变色层为单色转换液晶层；前屏还包括第一光学胶层、第二光学胶层和触感控制板；单色转换液晶层的第一表面与强化玻璃通过第一光学胶层粘接；单色转换液晶层的第二表面与显示屏的第一表面通过第二光学胶层粘接；显示屏的第二表面与触感控制板相贴合。
其中，在单色转换液晶层未接收到电压时，单色转换液晶层为透明状态。在单色转换液晶层接收到电压时，单色转换液晶层由透明状态转换为目标颜色。通过单色转换液晶层的工作原理可知，单色转换液晶层只能够在目标颜色与透明状态之间相互转换，由于单色转换液晶层能够显示的颜色单一，所以单色转换液晶层的耗电量少，单色转换液晶层可以在消耗较少电量的情况下显示目标颜色，而且，单色转换液晶层还可以在不消耗电量的情况下恢复至透明状态。
在一种可能的实现方式中，单色转换液晶层的厚度小于或等于0.1毫米。
其中，为了避免前屏整体的厚度太大，可以将单色转换液晶层的厚度控制在0.1毫米以内。
第二方面，本申请实施例提供了一种终端，该终端包括外壳和前屏；前屏设置在外壳上；前屏包括依次叠放的强化玻璃、光致可变色层和显示屏；显示屏发出的光照射进光致可变色层，光致可变色层用于在接收到显示屏发出的光线时变色。
在第二方面中，在光致可变色层未接收到显示屏发出的光线时，光致可变色层为目标颜色。在光致可变色层为目标颜色且光致可变色层接收到显示屏发出的光线时，光致可变色层由目标颜色转换为透明状态。通过光致可变色层的工作原理可知，光致可变色层在接收到显示屏发出的光线便可以由透明状态转换为目标颜色，而且，光致可变色层在未接收到显示屏发出的光线便可以由目标颜色转换为透明状态，光致可变色层在透明状态与目标颜色之间进行切换的过程中完全不消耗电量。
在一种可能的实现方式中，前屏还包括光学胶层和触感控制板；光致可变色层的第一表面固定在强化玻璃上；光致可变色层的第二表面与显示屏的第一表面通过光学 胶层粘接；显示屏的第二表面与触感控制板相贴合。
在一种可能的实现方式中，光致可变色层的厚度小于或等于0.05毫米。
其中，为了避免前屏整体的厚度太大，可以将光致可变色层的厚度控制在0.05毫米以内。
在一种可能的实现方式中，光致可变色层的材料为感光材料。

在图1至图3所示的实施例中，第一透明导电层221和第二透明导电层225具体可以为AZO，AZO是铝掺杂的氧化锌(ZnO)透明导电玻璃的简称。离子存储层222具体可以为五氧化二钒(V 2O 5)。离子导体层223具体可以为钽酸锂(LiTaO3)。
请结合图1和图4所示，图4所示的为本申请实施例提供的另一种前屏的示意图。在图1和图4所示的实施例中，前屏2包括依次叠放的强化玻璃31、第一光学胶层32、单色转换液晶层33、第二光学胶层34、显示屏35和触感控制板36。其中，单色转换 液晶层33与电路板3电连接，单色转换液晶层33用于在接收到电路板3的供电时变色。
在图1和图4所示的实施例中，强化玻璃31可以增加前屏的强度，以保护单色转换液晶层33、显示屏35和触感控制板36的安全。单色转换液晶层33可以在透明状态与目标颜色之间进行切换。第一光学胶层32可以将强化玻璃31与单色转换液晶层33粘接在一起。第二光学胶层34可以将单色转换液晶层33与显示屏35粘接在一起。显示屏35可以显示图像。触感控制板36可以接收用户输入的触控指令。
在图1和图4所示的实施例中，在单色转换液晶层33未接收到电路板3提供的电压时，单色转换液晶层33为透明状态。在单色转换液晶层33接收到电路板3提供的电压时，单色转换液晶层33由透明状态转换为目标颜色。通过单色转换液晶层33的工作原理可知，单色转换液晶层33只能够在目标颜色与透明状态之间相互转换，由于单色转换液晶层33能够显示的颜色单一，所以单色转换液晶层33的耗电量少，单色转换液晶层33可以在消耗较少电量的情况下显示目标颜色，而且，单色转换液晶层33还可以在不消耗电量的情况下恢复至透明状态。
在图1和图4所示的实施例中，显示屏25可以为LCD或OLED等屏幕。另外，为了避免前屏2整体的厚度太大，可以将单色转换液晶层33的厚度控制在0.1毫米以内。
请参见图1和图5所示，图5所示的为本申请实施例提供的又一种前屏的示意图。图5所示的前屏包括依次叠放的强化玻璃41、光致可变色层42、光学胶层43、显示屏44和触感控制板45。其中，显示屏44发出的光可以照射进光致可变色层42，光致可变色层42用于在接收到显示屏44发出的光线时变色。
在图1和图5所示的实施例中，强化玻璃41可以增加前屏的强度，以保护光致可变色层42、显示屏44和触感控制板45的安全。光致可变色层42可以在透明状态与目标颜色之间进行切换。光致可变色层42的材料可以为感光材料，例如，感光油墨。光学胶层43可以将光致可变色层42与显示屏44粘接在一起。显示屏44可以显示图像。触感控制板45可以接收用户输入的触控指令。
在图1和图5所示的实施例中，在光致可变色层42未接收到显示屏44发出的光线时，光致可变色层42为目标颜色。在光致可变色层42为目标颜色且光致可变色层42接收到显示屏44发出的光线时，光致可变色层42由目标颜色转换为透明状态。通过光致可变色层42的工作原理可知，光致可变色层42在接收到显示屏44发出的光线便可以由透明状态转换为目标颜色，而且，光致可变色层42在未接收到显示屏44发出的光线便可以由目标颜色转换为透明状态，光致可变色层42在透明状态与目标颜色之间进行切换的过程中完全不消耗电量。
在图1和图5所示的实施例中，显示屏44可以为LCD或OLED等屏幕。另外，为了避免前屏2整体的厚度太大，可以将光致可变色层42的厚度控制在0.05毫米以内。
在图1和图5所示的实施例中，可以采用物理气相沉积的方式将光致可变色层42设置在强化玻璃41上。具体的，物理气相沉积技术为在真空条件下采用物理方法将光致可变色层42的材料气化成气态原子，并将气态原子在强化玻璃41的表面沉积薄膜，该薄膜最终形成光致可变色层42。当然，将光致可变色层42设置在强化玻璃41上，并不局限于物理气相沉积，还可以采用其他的方式。
在图1至图5所示的实施例中，目标颜色可以为一种颜色，例如，目标颜色可以为红色、黄色或绿色等单一颜色。目标颜色也可以为几种颜色组合而成的颜色，例如，目标颜色可以为由红色、黄色或绿色等颜色组合而成的渐变色。
请参见图6所示，图6所示的为本申请实施例提供的一种移动终端的示意图。图6所示的移动终端包括外壳101、前屏102、电路板和电源，电路板和电源在图6中未示出。前屏102设置在外壳101上，电路板和电源均设置在外壳101内，电源与电路板电连接。其中，前屏102可以为图1至图5所示的实施例中的前屏2，关于前屏102的说明请参见图1至图5所示的实施例中对前屏2的说明。
在图6所示的实施例中，外壳101可以包括中框和后盖，前屏102和后盖分别固定在中框的两侧。
请结合图2和图6所示，如果图6所示的前屏102的具体结构如图2所示，那么前屏102包括依次叠放的强化玻璃21、电致变色组合层22、二氧化硅层23、光学胶层24、显示屏25和触感控制板26。
下面结合具体的应用场景来介绍图2和图6所示的实施例。例如，假设移动终端为智能手机，智能手机包括如图6所示的外壳101、前屏102、电路板和电源，前屏102的具体结构如图2所示的结构。假设智能手机的外壳101为蓝色。在显示屏25处于开启状态时，电致变色组合层22为透明状态。在显示屏25处于关闭状态时，智能手机的电路板会向电致变色组合层22的第一端施加电压，电致变色组合层22由透明状态转换为蓝色，从而使得前屏102的颜色与外壳101的颜色相同。在电致变色组合层22为蓝色且电致变色组合层22未接收到的电路板提供的电压时，电致变色组合层22会维持蓝色，所以电致变色组合层22不会消耗额外的电量。在显示屏25处于开启状态时，智能手机的电路板会向电致变色组合层22的第二端施加电压，电致变色组合层22由蓝色转换为透明状态，从而使得前屏102仅呈现显示屏25显示的图像。因此，前屏102可以在消耗较少电量的情况下显示蓝色，与外壳101保持一致，而且，前屏102还可以在消耗较少电量的情况下恢复至透明状态。
请结合图4和图6所示，如果图6所示的前屏102的具体结构如图4所示，那么前屏102包括依次叠放的强化玻璃31、第一光学胶层32、单色转换液晶层33、第二光学胶层34、显示屏35和触感控制板36。
下面结合具体的应用场景来介绍图4和图6所示的实施例。例如，假设移动终端为智能手机，智能手机包括如图6所示的外壳101、前屏102、电路板和电源，前屏102的具体结构如图4所示的结构。假设智能手机的外壳101为蓝色。在显示屏35处于开启状态时，单色转换液晶层33为透明状态。在显示屏35处于关闭状态时，智能手机的电路板会向单色转换液晶层33施加电压，单色转换液晶层33会由透明状态转换为蓝色，从而使得前屏102的颜色与外壳101的颜色相同。在显示屏35处于开启状态时，智能手机的电路板会停止向单色转换液晶层33施加电压，单色转换液晶层33会由蓝色转换为透明状态，从而使得前屏102仅呈现显示屏35显示的图像。因此，由于单色转换液晶层33能够显示的颜色单一，单色转换液晶层33的耗电量少，所以前屏102可以在消耗较少电量的情况下显示蓝色，与外壳101保持一致，而且，前屏102还可以在不消耗电量的情况下恢复至透明状态。
请结合图5和图6所示，如果图6所示的前屏102的具体结构如图5所示，那么前屏102包括依次叠放的强化玻璃41、光致可变色层42、光学胶层43、显示屏44和触感控制板45。
下面结合具体的应用场景来介绍图5和图6所示的实施例。例如，假设移动终端为智能手机，智能手机包括如图6所示的外壳101、前屏102、电路板和电源，前屏102的具体结构如图5所示的结构。假设智能手机的外壳101为蓝色。在显示屏44处于关闭状态时，光致可变色层42无法接收到显示屏44发出的光线，光致可变色层42为目标颜色。在显示屏44处于开启状态时，光致可变色层42会接收到显示屏44发出的光线，光致可变色层42会由蓝色转换为透明状态。因此，前屏102可以在不消耗电量情况下显示蓝色，与外壳101保持一致，而且，前屏102还可以在不消耗电量的情况下恢复至透明状态。
