阵列基板、 显示设备、 电子设备、 扫描方法以及扫描装置 技术领域
本发明的实施例涉及一种阵列基板、 显示设备、 电子设备、 扫描方法以 及扫描装置。 背景技术
现有触摸屏技术中, 根据触摸感应器(touch sensor )位置的不同, 可分 为 out-cell, on-cell和 in-cell三种方式,其中 out-cell是在 LCD外面直接加上 感应器, 这种方法使得整机整体厚度变厚, 而且透光率变低。 On-cell是在 LCD的彩色滤光片(Color Filter, CF)外侧制作感应器, 这种方法降低了整机 的厚度, 但是增加 CF的制作工序。 而 in-cell触摸技术直接在 LCD内制作, 不仅厚度不增加, 而且可以和 LCD—同制作, 没有额外的制作工序。 由于 in cell感应器的感应电压较小,并且 LCD内噪声复杂,对 in-cell感应器的影 响很大, 甚至不能完成触摸功能。

本发明通过在阵列基板上对应栅线设置一组扫描线, 并利用 LCD信号 没有变化的时间进行感测, 避免 LCD噪音。 附图说明
为了更清楚地说明本发明实施例的技术方案, 下面将对实施例的附图作 简单地介绍,显而易见地,下面描述中的附图仅仅涉及本发明的一些实施例, 而非对本发明的限制。
图 1表示本发明实施例所述的阵列基板的结构示意图;
图 2表示本发明实施例所述的感应线放电检测波形图;
图 3表示本发明实施例所述的对应扫描方法的波形图; 以及
图 4表示本发明实施例所述的扫描装置的主要结构示意图。 具体实施方式
为使本发明实施例的目的、 技术方案和优点更加清楚, 下面将结合本发 明实施例的附图,对本发明实施例的技术方案进行清楚、 完整地描述。显然, 所描述的实施例是本发明的一部分实施例, 而不是全部的实施例。 基于所描 述的本发明的实施例, 本领域普通技术人员在无需创造性劳动的前提下所获 得的所有其他实施例, 都属于本发明保护的范围。
图 1表示本发明实施例所述的阵列基板的结构示意图。
参见图 1所示, 阵列基板包括栅线 16和数据线 14, 以及形成在栅线和 数据线限定的像素区域内的像素电极 10和薄膜晶体管 12,阵列基板还包括: 平行于栅线 16并垂直于数据线 14的感应线 18, 用于在有触摸动作时, 通过 在第一时段内进行放电检测来确定被触摸点的位置。例如,感应线 18可以对 应于栅线 16设置。在一个实施例中,对应于每条栅线 16设置有一条感应线, 但根据本发明的实施例不限于此。
例如, 栅线和数据线彼此交叉。 在一个实施例中, 栅线和数据线彼此垂 直。
通过本实施例的上述技术方案,在阵列基板上对应栅线 16设置一组感应 线 18,感应线 18的线宽、形状等可根据 IC要求进行设计。触摸工作方法是: 对感应线 18充电后放电, 并检测感应线 18的放电情况。 图 2表示本发明实 施例所述的感应线放电检测波形图, 如果有触摸动作时, 由于诸如手指的触 摸体产生的电容 C— finger的加入, 导致感应线 18上的电容增加, 所以放电 时间增加。 并且本发明的实施例利用 LCD信号没有变化的时间 (在稍后进 行描述 )进行感测, 避免 LCD噪音。
可选地,感应线 18设置在栅线 16的上方或下方。例如, 感应线 18和栅 线 16之间彼此绝缘, 以在它们之间形成第一电容 CGS。
可选地, 感应线 18具有第一宽度以及与数据线 14交叉处的第二宽度, 第二宽度大于第一宽度。
在本实施例的上述技术方案中,感应线 18可以宽度不均匀,在与数据线 14的交叉处, 感应线 18可适当设置的略宽, 这样设置的好处是增大感应电 容。 图 1中虽然显示感应线 18和数据线 14彼此交叉,但感应线 18和数据线 14之间是彼此绝缘的, 以在它们之间形成第二电容 CGD, 即在感应线 18和 数据线 14的交叉处形成第二电容 CGD。
优选地, 第一时段为相邻的两条数据线信号之间的共享时间与相邻的两 条栅线信号之间的不重叠时间的交叠时间。
在本实施例的上述技术方案中, 在 LCD驱动中, 每相邻的两个数据线 14信号之间, 都会有一个电荷共享的时间 (TP ) , 用于降低功耗; 在每相邻 的两个栅线 16信号之间, 会有一个不重叠的时间 (OE ) , 用于防止相邻行 的串扰(如果上一行栅极在没有到关断之前, 本行数据信号输入就会使上一 行栅极误充电。为防止上述情况发生,使用 OE时间将上一行栅极提前关断 )。 本发明的实施例利用这个 TP和 OE这两个定时( timing ) 的交叠时间 ( T ) 进行感应线 18的放电检测。 由于是投影电容式的触摸方式, LCD的噪音影 响特别大, 所以需要在 LCD各条信号线(data、 gate, Vcom等)没有电压 变化时进行触摸扫描, 以避免 LCD的噪声对感应信号的干扰。
本发明的实施例提供的显示设备包括上述的阵列基板。
本发明的实施例提供电子设备包括上述的显示设备。
根据本发明实施例的扫描方法包括:
步骤 301 : 获取阵列基板上的相邻两条数据线信号之间的共享时间与相 邻的两条栅线信号之间的不重叠时间;
步骤 303: 比较共享时间与不重叠时间, 得到共享时间与不重叠时间的 交叠时间;
步骤 305: 根据交叠时间对阵列基板的感应线进行扫描, 得到一扫描结 果; 以及
步骤 307: 在扫描结果为感应线电容增加时, 确定阵列基板对应的触摸 屏被触摸。 图 3表示本发明实施例所述的对应扫描方法的波形图。 参见图 3所示, 由于是投影电容式的触摸方式, LCD 的噪音影响特别大, 所以需要在 LCD 各条信号线(data、 gate, Vcom等)没有电压变化时进行 touch扫描和感应, 触摸信号与 LCD信号的时序如下:
S: 感应线( sensor line ) ; G: 极线; Data: 数据线
每相邻的两个数据线信号之间, 都会有一个电荷共享的时间 (TP )用于 降低功耗; 在每相邻的两个栅线信号之间, 会有一个不重叠的时间 (OE )用 于防止相邻行的串扰(如果上一行栅极在没有到关断之前, 本行数据信号输 入就会使上一行栅极误充电。 为防止上述情况发生, 使用 OE时间将上一行 栅极提前关断) 。 本发明的实施例利用这个 TP和 OE这两个 timing的交叠 时间 ( T )进行感应线的放电检测。
通过本实施例的上述技术方案, 通过调整优化 LCD信号, 在栅极信号 和数据信号间隙完成触摸信号扫描, 解决了 LCD噪音的影响。
可选地, 在扫描结果为感应线电容增加时, 确定阵列基板对应的触摸屏 被触摸之后, 扫描方法还包括: 根据数据线、 栅线与感应线检测触摸屏被触 摸点的坐标关系; 根据坐标关系传输给触摸屏对应的主机, 以及通过主机启 动相关处理, 即通过主机获得触摸位置。
本发明的实施例提供的扫描装置包括: 获取模块 52, 用于获取阵列基板 上的相邻两条数据线信号之间的共享时间与相邻的两条栅线信号之间的不重 叠时间; 比较模块 54, 用于比较共享时间与不重叠时间, 得到共享时间与不 重叠时间的交叠时间; 扫描模块 56, 用于根据交叠时间对阵列基板的感应线 进行扫描, 得到一扫描结果; 以及确认模块 58, 用于在扫描结果为感应线电 容增加时, 确认阵列基板对应的触摸屏被触摸。
可选地, 扫描装置还包括检测模块(图中未示) , 用于根据数据线、 栅 线与感应线检测触摸屏被触摸点的坐标关系; 传输模块(图中未示) , 用于 将坐标关系传输给触摸屏对应的主机, 以及通过主机启动相关处理。
例如, 根据本发明实施例的显示设备和电子设备也可以包括上述扫描装 置, 以进行触摸检测。
根据本发明实施例的技术方案, 本领域技术人员应当发现, 本发明的实 施例通过 in-cell触摸技术直接在 LCD内制作, 不仅厚度不增加, 而且可以 和 LCD —同制作, 没有额外的制作工序。 并且通过在阵列基板上对应栅线 设置一组扫描线, 并利用 LCD信号没有变化的时间进行感测, 避免 LCD噪 音, 而且不影响 LCD开口率。
以上所述仅是本发明的示范性实施方式, 而非用于限制本发明的保护范 围, 本发明的保护范围由所附的权利要求确定。
