本发明实施例提供一种电容式触摸屏及终端, 能够在保证触摸显示屏的触摸性能的 同时, 无需设置用于覆盖出线区域的边框, 可以减少终端边框的宽度。 实施例 1
本发明实施例 1提供一种电容式触摸屏, 图 5为本发明实施例 1提供的技术方案的 一种实现方式。 参见图 5至图 7, 所述电容式触摸屏包括基板 6, 所述基板包括第一表 面和第二表面。 所述触摸屏还包括:
形成在所述基板的第一表面上的第一图形 8和第一出线 81,所述第一图形覆盖所述 基板的第一表面的部分区域, 所述第一出线为所述第一图形沿第一方向的出线, 所述第 一出线形成在所述基板的第一表面的除第一图形以外的剩余区域。
形成在所述基板的第二表面上的第二图形 9和第二出线 91,所述第二图形覆盖所述 基板的第二表面的部分区域, 所述第二出线为所述第二图形沿所述第一方向的出线, 所 述第二出线形成在所述基板的第二表面的除第二图形以外的剩余区域。
所述第一图形 8和第二图形 9为导电图形, 即由导电材质构成的图形, 为保证显示 效果, 所述导电材质可以为氧化铟锡 (IT0, Indium Tin Oxide ) 材料, 所述第一出线 81和第二出线 91由透明材质构成, 优选的, 所述出线的材质也可以为氧化铟锡 (IT0, Indium Tin Oxide) 材料。
其中, 所述第一表面和所述第二表面为所述基板的两个相对表面; 所述第二图形在 所述第一表面的垂直投影至少覆盖所述第一表面上除所述第一图形以外的剩余区域。
可以看出, 通过在基板的第一表面形成第一图形, 第二表面形成第二图形, 使所述 基板的每个表面分别可以在导电图形之外空余出一定区域进行出线, 由于第一表面的第 一图形和第二表面的第二图形呈现相互补充的关系, 因此通过两个表面的导电图形的相 互配合可以完成基板整体的触摸屏感应。 这样可以消除当前终端中存在的边框, 从而减 少终端边框的宽度。 实施例 2
本发明实施例 2提供一种电容式触摸屏, 为实施例 1提供的技术方案的具体实现方 式, 图 5为本发明实施例 2提供的电容式触摸屏的剖面示意图。 所述电容式触摸屏包含 基板 6, 在所述触摸屏基板外侧设有盖板 4, 所述 7为显示器, 所述显示器可以是液晶 显示器 LCD或发光二极管显示器 (Light Emitting Diode, LED) 或其他种类的显示器, 本发明实施例对此不进行限定。
本发明实施例 2主要对实施例提供的触摸屏进行说明, 如图 5所示, 所述基板 6的 第一表面为所述基板的上表面, 所述基板 6的第二表面为所述基板的下表面。 优选的, 所述第一图形从所述基板的第一侧边开始延伸, 并覆盖所述基板第一表面的部分区域; 所述第二图形从所述基板的第二侧边开始延伸, 并覆盖所述基板第二表面的部分区域; 其中,所述第一侧边和所述第二侧边为所述基板的两个相对侧边,在本发明实施例 2中, 所述第一侧边为所述基板的右侧边, 所述第二侧边为所述基板的左侧边, 所述第一图形 8形成在所述基板 6的上表面,所述第一图形 8在所述基板 6上表面的右侧边开始延伸, 并覆盖所述基板上表面的部分区域, 除第一图形以外的剩余区域用于进行所述第一图形 8的第一方向出线, 即第一出线 81。 所述第二图形 9形成在所述基板 6的下表面, 所述 第二图形 9在所述基板 6的下表面的左侧边开始延伸, 并覆盖所述基板下表面的部分区 域, 除第二图形以外的剩余区域用来进行所述第二图形 9的第一方向出线, 即第二出线 91。
下面将具体描述, 所述基板的第一表面如图 6所示, 在所述基板的第一表面上形成 了第一图形 8, 所述第一图形 8包括水平方向 (即 X方向) 的滑条和竖直方向 (即 Y方 向) 的滑条, 为方便说明, 图 6中用空白图案表示水平方向的滑条, 用斜条的图案表示 竖直方向的滑条。 在本示例中设定第一方向为水平方向, 即 X方向。 第一出线 81为所 述第一图形 8在水平方向的滑条的出线, 形成在所述基板第一表面上除第一图形 8以外 的剩余区域上。 在本发明实施例中, 可以通过导电图形的出线工艺, 将所有水平方向的 出线都走在所述第一图形 8的左侧。
同理, 所述基板的第二表面如图 7所示, 在所述基板的第二表面上形成了第二图形 9, 所述第一图形 9包括水平方向 (即 X方向) 的滑条和竖直方向 (即 Y方向) 的滑条, 为方便说明, 图 7中用空白图案表示水平方向的滑条, 用斜条的图案表示竖直方向的滑 条。 在本示例中设定第一方向为水平方向, 即 X方向。 第二出线 91为所述第二图形 9 在水平方向的滑条的出线, 第二出线 91形成在所述基板的第二表面上除第二图形 9以 外的剩余区域上。 在本发明实施例中, 可以通过导电图形的出线工艺, 将所有水平方向 的出线都走在所述第一图形 9的右侧。
需要说明的是, 如图 5所示的情况为所述第二图形 9在所述基板的第一表面上的垂 直投影会与所述第一图形 8重叠的情况, 这并不构成对本发明实施例的限制, 所述第二 图形 9在所述基板的第一表面上的垂直投影也可以与所述第一图形 8完全不重叠, 即所 述第二图形 9在所述第一表面的垂直投影刚好覆盖所述第一表面上除所述第一图形 8以 外的剩余区域的情况也是可行的。
进一步需要说明的是, 本发明实施例提供的技术方案仅为举例, 所述基板可以采用 玻璃基板或 Fi lm材质的基板, 优选为玻璃基板; 所述第一表面和第二表面没有上下层 的关系, 二者可以任意互换; 所述第一图形 8和第二图形 9均为导电图形, 其形状也没 有限制, 本发明实施例为描述清楚, 使用矩形图形进行描述, 但在实际应用中, 所述第 一图形 8和第二图形 9可以为其他形状 (例如三角形形状), 只要满足所述第二图形 9 在所述第一表面的垂直投影至少覆盖所述第一表面上除所述第一图形 8 以外的剩余区 域,且所述第一表面上除第一图形 8以外的剩余区域足够第一图形 8的第一出线 81,所 述第二表面上除所述第二图形 9以外的剩余区域足够第二图形 9的第二出线 91即可。 另外, 形成所述第一图形 8和所述第二图形 9时延伸的起始侧边也均可任意互换; 所述 第一图形 8和第二图形 9均为导电图形, 形成所述导电图形的图案在本实施的示范图中 使用了菱形, 实际应用中也可以为长方形、 正方形等, 本发明实施例对上述技术特征并 不进行限制。
由于所述第二图形 9在所述第一表面上的垂直投影覆盖了所述第一表面上除第一图 形 8之外的剩余区域, 因此可以保证整个基板 6在第一表面或第二表面的完整面积内都 有至少一层导电图形的完整覆盖, 具体来说, 所述第一表面上除第一图形 8以外的剩余 区域垂直在所述第二表面的投影区域有第二图形 9的覆盖,所述第二表面上除第二图形 9以外的剩余区域垂直在所述第一表面的投影区域有第一图形 8的覆盖, 因此可以保证 在两个表面上除图形区域以外的剩余区域均可以实现触摸性能,无需在触摸屏基板上导 电图形之外的区域预留出线区域, 如图 8所示, 因此可以实现触摸屏边框的有效减少甚 至消除。
另外, 优选的, 所述第一图形 8占第一表面的部分区域和 /或所述第二图形 9占第 二表面的部分区域可以为在所述基板第一侧边或第二侧边开始延伸的所述基板面积的 二分之一至三分之二; 在该区域范围内, 既能考虑到基板制作的平衡、 美观, 又能保证 所述第一图形区域和所述第二图形区域的面积之和能够完整覆盖整个基板面积的范围, 同时还能够增加所述第一图形区域在第二图形区域所在水平面上的投影与所述第二图 形区域的重叠区域的触摸定位精度。 实施例 3
本发明实施例 3提供一种使用如上述实施例所述的触摸屏的终端设备, 即本发明实 施例还提供一种终端, 所述终端包括触摸屏, 所述触摸屏包括基板, 所述基板包括第一 表面和第二表面, 所述触摸屏还包括: 形成在所述基板的第一表面上的第一图形和第一 出线, 所述第一图形覆盖所述基板的第一表面的部分区域, 所述第一出线为所述第一图 形沿第一方向的出线,所述第一出线形成在所述基板的第一表面的除第一图形以外的剩 余区域; 形成在所述基板的第二表面上的第二图形和第二出线, 所述第二图形覆盖所述 基板的第二表面的部分区域, 所述第二出线为所述第二图形沿所述第一方向的出线, 所 述第二出线形成在所述基板的第二表面的除第二图形以外的剩余区域; 其中, 所述第一 表面和所述第二表面为所述基板的两个相对表面; 所述第二图形在所述第一表面的垂直 投影至少覆盖所述第一表面上除所述第一图形以外的剩余区域。
由上可以看出, 通过在基板的第一表面形成第一图形, 第二表面形成第二图形, 使 所述基板的每个表面分别可以在导电图形之外空余出一定区域进行出线, 由于第一表面 的第一图形和第二表面的第二图形呈现相互补充的关系, 因此通过两个表面的导电图形 的相互配合可以完成基板整体的触摸屏感应。 这样可以消除当前终端中存在的边框, 从 而减少终端边框的宽度。 实施例 4

第一传感坐标分区单元 9031,用于根据所述第一图形的重合区域与非重合区域将所 述第一传感坐标划分为第一重合区域传感坐标和第一非重合区域传感坐标, 其中, 所述 第一图形的重合区域是指与所述第二图形在所述第一图形上的垂直投影重合的区域,所 述第一图形的非重合区域是指与所述第二图形在所述第一图形上的垂直投影不重合的 区域。 第二传感坐标分区单元 9032,用于根据所述第二图形的重合区域和非重合区域将所 述第二传感坐标划分为第二重合区域传感坐标和第二非重合区域传感坐标, 其中, 所述 第二图形的重合区域是指与所述第一图形在所述第二图形上的垂直投影重合的区域,所 述第二图形的非重合区域是指与所述第一图形在所述第一图形上的垂直投影不重合的 区域。
