为使本领域技术人员更好地理解本发明的技术方案， 下面结 合附图和具体实施方式对本发明的显示装置作进一步详细的描 述。 实施例 1 :
本实施例提供一种包含显示屏的显示装置， 包括内控本体以 及设置于所述内控本体一侧的触控单元， 所述触控单元包括触控 屏， 所述显示装置还包括副触控单元， 所述副触控单元设置于所 述内控本体的另一侧， 所述内控本体用于控制所述触控单元及所 述副触控单元。
所述副触控单元可以在受到用户的触碰时执行所述显示装置 的一部分功能。 例如， 所述副触控单元执行的功能是不需要为用 户提供大尺寸、 高亮度、 高对比度或多色彩等耗能较高的屏幕显 示的功能。 以所述显示装置为手机为例， 所述副触控单元可以具 有拨打电话的功能。 当用户通过副触控单元以实现电话呼叫和通 话时， 由于无需点亮显示装置的显示屏或触控屏， 而仅需启动耗 能很少的副触控单元， 因此， 该显示装置的能耗得到了很大程度 的减小。
优选地， 所述副触控单元可以包括副触控屏， 所述副触控屏 上设置有数字键、 符号键及功能键等。 作为替代， 功能键（比如 拨号键）还可以通过机械键实现。 实施例 2 :
本实施例提供一种包含显示屏的显示装置， 包括相适配且能 扣合在一起的前盖板、 侧盖板和后盖板。 如图 1 所示， 在由前盖 板 1、 侧盖板（图 1中未示出）和后盖板（图 1中未示出）扣合形 成的壳体内， 从上至下依次设置触控单元 2、 内控本体 3、 副触控 单元 4和局部供电单元 5 ,局部供电单元 5与副触控单元 4电连接， 以为副触控单元 4提供电源。
具体地， 触控单元 2设置于前盖板 1的内侧， 其包括触控屏， 触控屏与所述显示装置的显示屏集成为一体或分离设置， 此处不 具体限定， 能实现触控和显示功能即可。 内控本体 3设置于侧盖 板的内侧， 为用于完成显示装置的触控、 显示及其他必须功能的 整体， 例如， 本实施例中以显示装置为手机为例， 则内控本体 3 包括用于拨打电话、 接听电话、 发送消息和接收消息的通讯模块 和相应的电路、 以及为保证通讯能力而设置的射频模块及与射频 模块连接的射频天线等。 副触控单元 4与局部供电单元 5设置于 后盖板的内侧， 优选地， 与副触控单元 4相比， 局部供电单元 5 更靠近后盖板。 在本实施例中， 内控本体 3 用于控制触控单元 2 实现触控和显示功能及控制副触控单元 4 实现触控功能， 局部供 电单元 5与副触控单元 4电连接， 以为副触控单元 4提供电源。
优选地， 局部供电单元 5为太阳能电池板（也称光伏电池）， 太阳能电池板采用半导体工艺形成， 后盖板对应于太阳能电池板 的区域采用透明材料形成， 采用透明材料形成的区域的面积大于 或等于太阳能电池板的面积， 以保证太阳能电池板能接受充足的 太阳光照射， 从而将尽可能多的太阳能转化成电能。
在本实施例中， 如图 2所示， 副触控单元 4包括衬底 41以及 设置于衬底 41一侧的传感器电极 42 ,局部供电单元 5设置于衬底 41的另一侧、且与传感器电极 42电连接。为获得稳定的触控信号， 在副触控单元 4中， 在传感器电极 42的远离衬底 41的一侧还设 置有屏蔽层 44 , 屏蔽层 44与传感器电极 42对应设置， 屏蔽层采 用有机材料形成。 这里， 应该理解的是， 副触控单元与局部供电 单元均设置在后盖板的内侧即可， 即传感器电极相对更靠近后盖 板、 或是局部供电单元相对更靠近后盖板、 或是二者交融设置均 能保证副触控单元实现较好的触控效果以及局部供电单元实现对 副触控单元较好的供电效果。
优选的是， 传感器电极 42采用碳纳米管通过拉制工艺形成， 或采用石墨烯材料通过构图工艺形成。 如图 2所示， 本实施例中， 副触控单元和局部供电单元的形成过程为： 在衬底 41的一侧涂覆 固化材料， 通过预烘干使固化材料内的溶剂部分挥发， 然后在固 化材料上通过拉制工艺形成传感器电极 42 , 之后， 在传感器电极 42的上方形成屏蔽层 44; 将衬底 41翻转， 在衬底 41的另一侧形 成局部供电单元 5 , 例如采用半导体工艺形成太阳能电池板。在图 2所示的示意图中， 传感器电极 42的面积较大， 几乎覆盖了对应 于后盖板的除用于设置天线和摄像头的区域（即图 2中衬底 41上 方无图案部分的区域） 以外的全部区域， 在实际形成过程中， 可 以根据显示装置的电路设计或功能键的形状、 大小和位置设计， 适当地调整传感器电极的形状、 面积和位置， 以便能同时获得较 好的触控效果和较低的生产成本。
在本实施例中， 由于碳纳米管和石墨烯材料均适用于柔性显 示， 相应地， 采用适用于柔性显示的衬底 41 , 可使得副触控单元 4还延伸至侧盖板与内控本体 3之间； 而且， 侧盖板和后盖板上设 置有与副触控单元 4电连接的功能键， 功能键包括音乐播放功能、 时间播报功能、 接听电话功能等多种功能， 功能键可以设置在显 示装置的后盖板的外侧或侧盖板的外侧； 而且， 功能键可以设置 一个或多个， 既可以一个功能键仅具有一个功能， 也可以一个功 能键具有一个以上功能。
图 3为根据本发明的实施例 2的显示装置的功能键的分布示 意图。 如图 3 所示， 例如， 显示装置为手机， 优选地， 音乐播放 键 81和时间播报键 82分别设置在左、 右侧盖板 6的外侧上， 电 话接听键 83设置在后盖板 7的外侧上， 每个功能键通过其定义的 功能及操作方式进行操作即可实现相应的功能。 进一步优选的是， 副触控单元 4还设置有副触控屏 45 ,其中设置有数字键及符号键， 且通过传感器电极 42实现其触控功能。后盖板 7的外侧上还设置 有拨打电话键 84 ,拨打电话键 84与副触控单元 4电连接， 以通过 副触控单元 4实现拨打电话的功能。 副触控屏 45可以嵌入在后盖 板 7中， 或者可以使后盖板 7的对应于副触控屏 45的部分由透明 材料形成， 此处不具体限定， 只要能实现相应的功能即可。 副触 控屏 45优选地为由玻璃或塑料等材料形成的透明基板， 副触控屏 45 中的数字键及符号键可以为不需点亮即可进行操作的虚拟按 键、 或者为仅需局部点亮即可进行操作的按键。 与显示屏及触控 屏相比， 副触控屏 45仅用于数字键和符号键的操作， 在操作过程 中无需像显示屏及触控屏那样全屏点亮， 因此， 仅用较少的电量 即可完成电话的拨打。 同样， 可以在不点亮显示屏及触控屏的情 况下通过副触控单元 4 而仅用较少的电量即可完成音乐播放、 时 间播报和电话的接听。
在本实施例中，显示装置中还包括电池单元和电量监控模块， 当局部供电单元 5 (例如，太阳能电池板）的电量小于设定电量时， 副触控单元 4切换至与电池单元电连接， 以通过电池单元为副触 控单元 4提供电源。 例如， 可以事先将副触控单元 4 同时连接至 电池单元和局部供电单元，首选通过局部供电单元为副触控单元 4 供电， 但当局部供电单元 5 的电量不足时， 例如， 当局部供电单 元 5的电量为副触控单元 4的额定工作电量的 30%时，将局部供电 单元 5切换至电池单元来向副触控单元 4供电。
本实施例的显示装置中，触控单元的触控屏可以通过 on- ce l l 模式、 in- cel l模式或 0GS ( One Glass Solut ion, 即单玻璃解决 方案）模式设置在显示装置的显示屏中， 其中， 显示屏可以为 LCD 显示屏或 0LED显示屏。 此外， 显示装置还可以为手持电台、 电子 播放器、 液晶显示器、 电子书、 0LED显示器、 平板电脑、 数码相 框等具有触控和显示功能的任意产品或部件， 本发明尤其适用于 手持式的显示装置。 实施例 3:
本实施例相对于实施例 2的区别在于， 副触控单元与局部供 电单元的相对位置不同。
在本实施例中，副触控单元 4包括衬底 41以及依次设置于衬 底 41的一侧的传感器电极 42和绝缘层 43 , 局部供电单元 5设置 于绝缘层 43的远离衬底 41的一侧、 且与传感器电极 42电连接， 此外， 在局部供电单元 5的远离衬底 41的一侧设置有屏蔽层 44。
如图 4所示， 本实施例中， 副触控单元 4和局部供电单元 5 的形成过程为： 在衬底 41的一侧形成传感器电极 42 ,接着在传感 器电极 42的上方形成绝缘层 43, 然后在绝缘层 43的上方形成局 部供电单元 5 , 在局部供电单元 5的上方形成屏蔽层 44。 其中， 绝缘层 43和屏蔽层 44采用有机材料形成， 绝缘层 43使得传感器 电极 42与局部供电单元 5之间具有更好的独立性， 屏蔽层 44能 更好地屏蔽外部电磁干扰， 从而使得副触控单元 4 的触控灵敏度 更高。 当然， 在上述结构中， 屏蔽层 44 也可以设置在绝缘层 43 的远离衬底 41的一侧， 此时， 屏蔽层 44与绝缘层 43在某种程度 上可视为同时兼顾了绝缘和防电磁干扰的双重功能的一层。
同样， 应该理解的是， 副触控单元 4和局部供电单元 5的设 置结构也可以依次为： 衬底 41、 局部供电单元 5、 绝缘层 43、 传 感器电极 42和屏蔽层 44 , 如图 5所示。 或者， 副触控单元 4和局 部供电单元 5的设置结构也可以依次为： 衬底 41、 局部供电单元 5、 绝缘层 43、 传感器电极 42 , 并在衬底 41的另一侧设置屏蔽层 44。 事实上， 屏蔽层 44的设置位置可以根据副触控单元 4的传感 器电极 42的设置位置而改变， 只要能实现相应的屏蔽功能即可。
本实施例中显示装置的其他结构与实施例 2相同， 这里不再 赘述。
实施例 4:
本实施例与实施例 3的区别在于， 本实施例中， 触控单元不 包括衬底。
本实施例中， 副触控单元 4的传感器电极 42设置于后盖板 7 的内侧， 局部供电单元 5设置于传感器电极 42的远离后盖板 7的 一侧、 且与传感器电极 42电连接。 优选的是， 副触控单元 4还包 括绝缘层 43和屏蔽层 44 ,绝缘层 43设置于传感器电极 42与局部 供电单元 5之间， 屏蔽层 44与传感器电极 42对应设置、 且位于 传感器电极 42的远离后盖板 7的一侧， 绝缘层 43和屏蔽层 44均 采用有机材料形成。
本实施例中显示装置的其他结构与实施例 3相同， 这里不再 赘述。 相比实施例 3 , 本实施例中的后盖板 7相当于实施例 3的衬 底和后盖板的合体， 由于其组成部件相对减少， 因此该显示装置 的结构更筒单、 组装更方便、 成本也更低。 实施例 5 :
本实施例与实施例 2或 3的区别在于， 本实施例中显示装置 的副触控单元与局部供电单元分离设置， 局部供电单元依附并设 置在后盖板上。
在本实施例中，副触控单元 4的衬底 41的两侧均设置有传感 器电极 42 , 局部供电单元 5设置于后盖板 7的内侧、 且分别与衬 底 41的两侧的传感器电极 41电连接。
本实施例中显示装置的其他结构与实施例 2或 3相同， 这里 不再赘述。 实施例 6 :
本实施例与实施例 2-5 中的任一个的区别在于， 传感器电极 的结构不相同。
在本实施例中，传感器电极 42包括分离的第一电极和第二电 极， 第一电极与第二电极之间设置有介质层， 第一电极和第二电 极分别采用碳纳米管与氧化铟锡形成、 或者分别采用碳纳米管与 石墨烯形成， 介质层采用有机材料形成。
本实施例中显示装置的其他结构与实施例 2-5 中的任一个相 同， 这里不再赘述。 实施例 7 :
本实施例与实施例 2-6中的任一个的区别在于，本实施例中， 副触控单元不包括副触控屏。
本实施例中， 由于未设置副触控屏， 相应地， 如图 6所示， 例如显示装置为手机时， 后盖板 7和侧盖板 6上设置的功能键可 以仅包括音乐播放键 81、 时间播报键 82、 接听电话键 83 , 上述功 能键与副触控单元电连接， 以通过副触控单元实现相应的功能。 本实施例中， 由于拨打电话需借助显示装置的显示屏和 /或触控单 元的触控屏、 以及其中的数字键、 符号键和功能键， 因此需全屏 点亮显示装置的显示屏和 /或触控单元的触控屏才能拨打电话。 当 然， 当不设置副触控屏时， 可以在副触控单元 4 中将数字键、 符 号键等设置为虚拟按键或实体按键， 当为虚拟按键时， 可以采用 触摸按键即点亮该按键而其他按键均不点亮或仅部分点亮的方式 进行操作。 可以理解的是， 无论副触控单元是否包含副触控屏， 均不影响副触控单元的功能的实现。 但是， 由于省略了副触控屏 的设置， 因此， 本实施例的显示装置的成本相对实施例 2-6 中的 任一个的显示装置具有更低的成本。
本实施例中显示装置的其他结构与实施例 2-6 中的任一个相 同， 这里不再赘述。 实施例 1-7的显示装置中， 通过在显示装置的后盖板的内侧 设置副触控单元和局部供电单元， 在无需全屏点亮显示装置的显 示屏及触控单元的触控屏的情况下即可进行音乐播放、 时间播报， 接听电话、 甚至拨打电话等多种功能的操作， 大大节省了显示装 置本身的耗电， 增强了显示装置的续航能力， 从而能够满足需要 为显示装置长时间供电的应用。 可以理解的是， 以上实施方式仅仅是为了说明本发明的原理 而采用的示例性实施方式， 然而本发明并不局限于此。 本发明的 实施例可以省略上述技术特征中的一些技术特征， 仅解决现有技 术中存在的部分技术问题， 而且， 所公开的技术特征可以进行任 意组合。 对于本领域内的普通技术人员而言， 在不脱离本发明的 精神和实质的情况下， 可以做出各种变型和改进， 这些变型和改 进也视为本发明的保护范围。 本发明的保护范围由所附权利要求 限定。
