为了更清楚地说明本公开实施例中的技术方案，下面将对实施例描述中所需要使用的 附图作简单地介绍， 显而易见地， 下面描述中的附图仅仅是本公开的一些实施例， 对于本 领域普通技术人员来讲， 在不付出创造性劳动的前提下， 还可以根据这些附图获得其他的 附图。

此处的附图被并入说明书中并构成本说明书的一部分， 示出了符合本发明的实施例， 并与说明书一起用于解释本发明的原理。 具体实施方式
为使本公开的目的、技术方案和优点更加清楚， 下面将结合附图对本公开实施方式作 进一步地详细描述。
实施例一
图 1是根据一示例性实施例示出的一种触摸屏， 该触摸屏包括： 两块玻璃盖板 101、 一挠性薄膜 102、 涂覆在挠性薄膜 102上的 ITO涂层 103、 透明粘合层 104、 以及与 ITO 涂层 103电连接的 FPC (Flexible Printed Circuit board, 柔性电路板） （图未示） 。 两块玻 璃盖板 101包括主玻璃盖板 1011和辅玻璃盖板 1012，主玻璃盖板 1011的侧边与辅玻璃盖 板 1012的侧边固定连接， 且主玻璃盖板 1011的板面和辅玻璃盖板 1012的板面之间呈夹 角，挠性薄膜 102通过透明粘合层 104粘接在玻璃盖板 101上，且 ITO涂层 103位于挠性 薄膜 102和玻璃盖板 101之间。
例如，挠性薄膜 102可以为聚酯薄膜。 由于实施例中的 ITO涂层 103涂覆在挠性薄膜 102上， 而挠性薄膜 102柔软易弯曲， 所以使得挠性薄膜 102及其上的 ITO涂层 103可以 随着玻璃盖板之间的夹角而弯曲， 并贴合在玻璃盖板上。
在实施例中， ΠΌ涂层 103的边缘镀有狭长的电极。 以矩形薄膜为例， 在 ITO涂层的 四边镀有 4个狭长电极， 且 4个电极与控制电路 （设于 FPC上） 连接。 当用手指触摸屏 幕时， 由于人体带电，手指与 ITO层间会形成一个耦合电容， 电极发出的电流会流向触点， 而电流强弱与手指到电极的距离成正比， 控制电路计算电流的比例及强弱， 准确算出触摸 点的位置。 另外， ITO涂层上印有图案， 该图案可以是菱形或其他图形。
例如， 透明粘合层 104可以为光学胶层。
需要说明的是， 本实施例中， 玻璃盖板的数量为两块， 主玻璃盖板和辅玻璃盖板的数 量为各一块， 但是其数量并以此为限， 可以根据实际需要设置。 此外， 主玻璃盖板和辅玻 璃盖板之间的夹角也可以根据实际需要设置， 例如， 15〜90度。
本公开实施例提供的触摸屏通过采用挠性薄膜作为 ΠΌ涂层的基板，使得在两块或者 两块以上玻璃盖板组合，且两块玻璃盖板之间存在夹角时， 可以通过只通过一张 ITO涂层 和一个控制电路来检测来自两块玻璃盖板的动作，在满足电子产品工业外观设计多样化需 求的同时， 降低了触摸屏成本。
实施例二
图 2-4分别是根据一示例性实施例示出的一种触摸屏的结构示意图、侧视图及俯视图， 其中触摸屏包括： 主玻璃盖板 2011、 第一辅玻璃盖板 2012、 第二辅玻璃盖板 2013、 一挠 性薄膜 202、 ITO涂层 203、 透明粘合层 204以及 FPC (图未示） 。
在本实施例中， ITO涂层 203涂覆在挠性薄膜 202上， 主玻璃盖板 2011的侧边分别 与第一辅玻璃盖板 2012和第二辅玻璃盖板 2013的侧边固定连接， 且主玻璃盖板 2011的 板面分别与第一辅玻璃盖板 2012的板面和第二辅玻璃盖板 2013的板面之间呈夹角，挠性 薄膜 202通过透明粘合层 204粘接在玻璃盖板上， ITO涂层 203位于挠性薄膜 202和玻璃 盖板之间， FPC与 ITO涂层 203电连接。
例如，挠性薄膜 202可以为聚酯薄膜。 由于实施例中的 ITO涂层 203涂覆在挠性薄膜 202上， 而挠性薄膜 202柔软易弯曲， 所以使得挠性薄膜 202及其上的 ITO涂层 203可以 随着玻璃盖板之间的夹角而弯曲， 并贴合在玻璃盖板上。
容易知道， ITO涂层 203的边缘镀有狭长的电极。 以矩形薄膜为例， 在 ITO涂层的四 边镀有 4个狭长电极， 且 4个电极与控制电路 （设于 FPC上） 连接。 当用手指触摸屏幕 时， 由于人体带电， 手指与 ΠΌ层间会形成一个耦合电容， 电极发出的电流会流向触点， 而电流强弱与手指到电极的距离成正比， 控制电路计算电流的比例及强弱， 准确算出触摸 点的位置。 另外， ITO涂层上印有图案， 该图案可以是菱形或其他图形。
例如，透明粘合层 204可以为光学胶层。透明粘合层 204主要是将玻璃盖板与 ITO涂 层 203粘接起来。
在本实施例中， 触摸屏还可以包括： 间隔条 205， 主玻璃盖板 2011和第一辅玻璃盖板 2012通过间隔条 205连接，主玻璃盖板 2011和第二辅玻璃盖板 2013通过间隔条 205连接。 该间隔条 205可以是塑料间隔条、 橡胶间隔条或金属间隔条等。
需要说明的是， 玻璃盖板的数量为三块， 主玻璃盖板的数量为一块， 辅玻璃盖板的数 量为两块， 但是其数量并以此为限， 可以根据实际需要设置。 此外， 主玻璃盖板和辅玻璃 盖板之间的夹角也可以根据实际需要设置， 例如， 15〜90度。
本公开实施例提供的触摸屏通过采用挠性薄膜作为 ιτο涂层的基板，使得在两块或者 两块以上玻璃盖板组合，且两块玻璃盖板之间存在夹角时， 可以通过只通过一张 ITO涂层 和一个控制电路来检测来自两块玻璃盖板的动作，在满足电子产品工业外观设计多样化需 求的同时， 降低了触摸屏成本。
