触觉反馈显示屏及其制造方法
【技术领域】
本发明涉及用户使用的显示终端领域,尤其涉及一种触觉反馈显示屏。
【背景技术】
随着科技的快速发展,"智能"的便携式电子设备,如智能手机、平板电脑等,正变得越来越强大的计算工具。在今天的社会,不久前手机是只打了个电话十二键键盘的简单设备。今天,"智能"手机、平板电脑、个人数字助理和其他便携电子设备不仅拨打电话,还通过显示屏进行管理通讯簿、维护日历、播放音乐和视频,显示图片和在英特网上冲浪。
某些显示屏幕也用作触摸基于输入的组件。这些触摸屏都能够给用户,用户可以通过触摸显示屏来选择显示不同的文本和图形。更具体地说,可以配置触摸屏,向用户显示虚拟按钮和其他类型的选项。主流的触摸显示计算的兴起带来了很多计算机用户的可用性好处,然有视觉障碍的人往往与触摸显示用户界面交互时要经受重大挑战。触摸显示器的一大特色是以便能直接操纵信息用他们的指尖,但这种能力通常对盲人用户,不能看到或感觉到的视觉信息,提出了一种挑战。
幸运的是,许多主流触摸显示设备现在为盲人和视力受损的用户提供触觉反馈。美国专利号7,148,875提供触觉反馈控制直接应用的外力到触摸显示器,用户的手指可以感受到力量的方式,和一种触摸板触觉反馈装置或运动。为此,一个或多个驱动器被耦合到触摸屏来施加一个力直接去触摸显示器表面。在一个实施例中,致动器包括压电驱动器、音圈、电动机或电磁耦合到触摸板。目前,可以跟踪和大多数基于成像的触摸显示系统上使用触摸屏。而一些触摸面板包括触觉的叠加可透明的材料,如丙烯酸塑料,触摸屏是触摸表面很滑。因长时间使用损坏,触摸屏的触摸表面是严重磨损和几乎难以辨认。
因此,有必要提供一种新型的触觉反馈显示屏来解决上述技术问题。
【发明内容】
本发明的目的在于解决上述显示屏不能准确反馈触觉的问题,而提供一种触觉反馈显示屏。
本发明触觉反馈显示屏,包括:一显示单元用以显示数字信息,一触摸板用以接收反馈外部信号,一玻璃制成的触觉覆盖层,设置在所述显示单元和触摸板的外部,所述触觉覆盖层设有光滑的外表面,所述外表面上设有热压工艺成形的凸起能触摸感知的触觉单元。
优选的,所述触觉覆盖层上所设的触觉单元是通过一TaC涂层硬质合金模具热压工艺成型。
优选的,所述触觉单元包括呈山脊状的第一触觉单元。
优选的,所述触觉单元包括呈凸起圆点状的第二触觉单元。
与相关技术相比,本发明提供的触觉反馈显示屏,包括一显示单元用以显示数字信息,一触摸板用以接收反馈外部信号,一玻璃制成的触觉覆盖层,设置在所述显示单元和触摸板的外部,所述触觉覆盖层设有光滑的外表面,所述外表面上设有热压工艺成形的凸起能触摸感知的触觉单元,可为视觉障碍的使用者提供便捷。而且本发明结构简单便于制造,可降低制造成本,可大规模推广应用。
【附图说明】
图1为本发明带有触觉反馈显示屏的终端设备立体图;
图2为图1中触觉反馈显示屏的截面示意图;
图3为图1中触觉反馈显示屏的结构示意图;
图4为本发明触觉反馈显示屏的制备图。
【具体实施方式】
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部份实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动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。
请参阅图1,为本发明提供的一设有触觉反馈显示屏的手机100,它包括一矩形外壳10,与外壳10配用的触摸屏10a,和主按钮20。在本实施例中,所述主按钮20可以与触摸屏10a分离设置,也可以整体设置在一整个屏上。
参阅图2和图3所示,所述触摸屏10a可带选择的包括有显示单位13、触摸板12和触觉覆盖层11。显示单位13用于输出的手机中的100内容,如图像数据、控制操作和功能设置的用户运行期间生成的状态信息。所述触摸板12作为接收触摸用户输入的输入设备。触摸板12可以选择安装在显示单位13的整个表面以便检测所接收的信号,如触碰的物理外力引起触摸信号,并传送到手机100的控制单元。所述触摸板12可能使用一种压力传感器的压力型触摸屏、电阻式触摸屏、电容式触摸屏、表面声波触摸屏、红外触摸屏或感应触摸屏。由于触摸板12的原理已被其他文件揭示,此处省略及其依据的说明。触觉覆盖层11的制备材料为透明光滑的玻璃,完全安设在手机100表面。所述触觉覆盖层11可以保护触摸屏12和显示单元13,并允许数据显示触摸屏10a上。触觉覆盖层11进一步包括触觉单元21被设置在光滑的外表面能够被手指所触摸到。在本实施例中,所述触觉单元21被设置成凸起的呈山脊状的第一触觉单元21a和凸起的呈圆点的第二触觉单元21b。当然,所述触觉单元21的形状不限于此处所述的山脊状或圆点状,也可以只设置成一个形状。
在本实施例中,可以将触觉单元21设置在触摸屏10a的外光滑表面上,也可以设置在主按钮20上。
所述触觉覆盖层11是由玻璃材料制成,设置在触觉覆盖层11上的触觉单元21是通过模具由抗耐磨的TaC(Tetrahedral Amorphous Carbon)涂层硬质合金模具热压成型。
如图4所示,所述TaC涂层硬质合金模具包括公模31和与公模31配用的母模32。所述母模32设有提供对应触觉单元21的触觉压痕33。本实施例中制备触觉覆盖层11上的触觉单元21的方法是︰提供一平板状的待压触觉覆盖层11`,放入TaC涂层硬质合金模具中通过公模31和母模32的热压处理,在待压触觉覆盖层11`的表面11a形成所述触觉单元21。
通过执行本方法,所述触觉单元21可以在触觉覆盖层11上设计批量生产。所述触觉单元通过热压成形技术集成印在触觉覆盖层11的玻璃面板,大大降低了制造成本。.
以上所述的仅是本发明的实施方式,在此应当指出,对于本领域的普通技术人员来说,在不脱离本发明创造构思的前提下,还可以做出改进,但这些均属于本发明的保护范围。
