Description

具有触觉输出的触摸显示屏及触觉输出装置
技术领域
[0001] 本申请涉及触摸显示屏， 特别是一种具有触觉输出功能的触 摸显示屏。
背景技术.
[0002]触摸显示屏越来越被广泛的应用到交互式电子产品上， 例如 手机、显示器、平板电脑甚至电视机上。使用者通过触摸屏幕完成命 令输入，一般来说，触摸显示屏会以一定方式向用户反馈其输入已经 到达。
[0003]现有的反馈方式有音像反馈， 或者通过手机或电脑中的偏心 电机，不管屏幕哪一处有触摸输入偏心电机都会产生机械振动实现反 馈，或者在触摸屏下方设置多个可垂直于屛的方向机械运动的致动装 置， 当屏有触摸输入时，触摸点处的致动装置便会产生机械形变实现 反馈。
[0004]音像反馈方式存在以下缺点： 当在嘈杂的环境中使用时， 例 如车站、机场、 闹市， 声音反馈被环境噪音所湮没； 当在光线较为充 足的环境使用时， 例如： 阳光充足的户外或灯光明亮的室内， 图像反 馈也不易被用户察觉。
[0005]偏心电机机械振动反馈存在以下缺点: 不管触摸输入发生在 屏的哪个位置，偏心电机都会带动整机振动，反馈信息的针对性较差 且用户体验不佳。
[0006] 上述第三种反馈方 j¾存在以下缺点： 成本高， 为了能在每一 个触摸输入处都产生形变， 需要大量的致动装置； 分辨率限制， 由于 致动装置体积较大， 以及安装工作复杂等因素， 形变（即触觉）输出 点的密度难以做到很高， 因而分辨率较低；机械式的致动装置容易损 坏且维修困难； 由于致动装置运动方向是垂直于屏的,致动装置运动 时会将屏顶起进而将 "触觉"传达至用户手指， 屏长期的受到致动装 置的顶压， 易老化、 疲劳、 产生永久形变。

[0033] 触摸屏单元 2包括底板 6， 底板 6上设置有电极对， 每个电极 对中包含正电极及负电极。控制器与各个电极对的正负电极连接， 如 图 2。 控制器根据触摸屏单元 2输入的触觉信息 （如触觉输入发生的 位置坐标信息）， 通过在与此触摸屏单元附近的正负电极上施加一定 频率、 强度的电压差从而使电极放电， 产生电流最终形成 "触觉"。
[0034] 所述的电压差应不高于人体能承受的安全电压 36V，电极之间 的电流不超过 14mA的人体安全电流，例如可选用安全电压电流范围 内的一定频率的脉冲电流。
[0035] 所述触摸屏单元与触觉输出单元可以位于同一层， 如图 3、 4； 也可以将触觉输出单元 2设置在触摸屏单元 3的上层， 如图 1。
[0036] 对于将触觉输出单元设置在触摸屏单元的上层的实施例， 在 其中一个实施例中，所述触摸屏单元 3又分为触觉输入子单元 301与 显示输出子单元 302，多个触觉输出单元组成触觉输出层位于最顶层， 多个触觉输入子单元组成触觉输入层位于中层，多个显示输出子单元 302组成显示输出层位于最下层， 如图 7。
[0037] 图 1、 图 7显示的实施例中， 控制器可以使触摸屏单元与触觉 输出单元分时独立工作， 从而分时实现触觉输入、信息显示及触觉输 出功能。
[0038] 将触摸屏单元与触觉输出单元设置于同一层的一个实施例如 图 3， 显示屏包括多个触摸屏单元组 5以及多个触觉输出单元组 4， 且触摸屏单元组 5与触觉输出单元组 4交替平行排列；每个触摸屏单 元组 5由多个触摸屏单元 3线性排列形成；每个触觉输出单元组 4由 多个触觉输出单元 2线性排列形成。

[0040] 实际应用中， 也存在这样的实施例， 如图 5、 图 8， 所述触摸 屏单元 3又分为触觉输入子单元 301与显示输出子单元 302; 多个触 觉输入子单元 301与多个触觉输出单元 2交替排列在同一层；所述多 个显示输出子单元 302组成显示输出层位于所述触觉输入子单元 301 与触觉输出单元 2所在层的下一层。

[0042] 在本申请公开内容的教导下， 本领域技术人员无需创造性劳 动便可知晓， 在电压、 电流安全范围内， 改变电压的强度、 频率会引 起不同的 "触觉"强度及类型； 改变触觉输出单元上电极对的密度及 分布位置， 可以改变 "触觉"的分辨率； 甚至人们可以追踪触觉输入 位置， 改变触觉输出位置， 使用户手指感觉到滑动的 "触觉"； 也可 以使显示屏上显示的虚拟按键图像上的触觉输出单元上的电极输出 电流， 而其余位置电极无电流输出， 用户便可感知到"凸起的按键"。
[0043] 以上所述仅为本申请的较佳实施例而已， 并不用以限制本申 请， 凡在本申请的精神和原则之内所作的任何修改、等同替换和改进 等， 均应包含在本申请的保护范围之内。
