下面将结合本公开实施例中的附图，对本公开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公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另作定义，此处使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开专利申请说明书以及权利要求书中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”或者“一”等类似词语也不表示数量限制，而是表示存在至少一个。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也相应地改变。
下面将结合附图对本发明的实施例进行详细描述。
图1示出了根据本发明实施例的触觉反馈系统。该触觉反馈系统可以让人真实感受到所触摸的显示物体的软硬度和/或温度等。如图1所示，触觉反馈系统包括可触摸的显示屏11、反馈构件阵列12和触觉反馈控制器14。显示屏11显示画面和接收用户触摸信息；触觉反馈控制器14与显示屏11和反馈构件阵列12电连接，根据显示屏11显示的画面和用户触摸的位置，对于反馈构件阵列12发出相应的控制信号；反馈构件阵列12包括多个反馈构件13，位于显示屏11下方，根据触觉反馈控制器14发出的控制信号来对用户触摸的位置提供相应的反馈。反馈构件阵列12可以是提供力反馈的机械反馈构件阵列和/或提供温度反馈的温度反馈阵列等。例如，对于显示画面中比较热的物体，反馈构件阵列12的相应部分的反馈构件13发出相应的高温，用户通过触摸就能感知物体的热度，对于显示画面中比较冷的物体，反馈构件阵列12的相应部分的
反馈构件13发出相应的低温，用户通过触摸就能感知物体的冷度；对于显示画面中比较硬的物体，反馈构件阵列12的相应部分的反馈构件13提供较高等级的力反馈，用户通过触摸就能感知物体较硬，对于显示画面中比较软的物体，反馈构件阵列12的相应部分的反馈构件13提供较低等级甚至相反的力反馈，用户通过触摸就能感知物体较软。
下面以提供力反馈的机械构件阵列为例，详细说明本发明的实施例。显示屏11为柔性显示屏，可实现柔软显示，在手指按压时有一定的形变量。反馈构件阵列12是提供力反馈的机械反馈构件阵列，由多个独立控制的机械反馈构件13构成，便于以合适的组合控制对应于用户触摸区域进行对应等级的力反馈，并且机械反馈构件13可以根据控制信号而在垂直于屏幕的方向上运动。机械反馈结构阵列12中的反馈构件13可以采用规则的二维布置，或者采用跟触摸图案相似的布置。机械反馈结构阵列12中的每一个机械反馈构件13可以被独立控制。机械反馈构件13例如可以采用弹簧组件或者压电器件等制成。
如图2所示，机械反馈构件13采用弹簧组件制造。其包括上平面体21、下平面体23、位于上平面体21与下平面体23之间的弹簧22和位于上平面体21与下平面体23中的至少一侧上的可升降结构24。例如，在图2中，可升降结构24位于下平面体23下方。当需要较高等级的力反馈时，可升降结构24向上升使得弹簧22压紧，从而在对应的柔性屏的相应位置，柔性屏难以被按下，产生硬的效果；当需要较低等级的力反馈时，可升降结构24向下降使得弹簧22松弛，从而在对应的柔性屏的相应位置，柔性屏容易被按下，产生软的效果。
下面以压电器件为例来具体说明根据本发明实施例的机械构件。如图3A至3C所示，压电器件包括上极板31、下极板32和位于上极板31与下极板32之间的压电晶体33。压电晶体33具有逆压电效应，即电致伸缩效应，能将电能转化为机械运动，即压电晶体33能在电场的作用下由于感应极化作用而产生形变。正常状态下，即未施加电场时，如图3A所示，压电晶体33中的晶体散乱排布；当在电介质两端施加电场时，压电晶体在电场的作用下成规则排布，从而产生应力。具体而言，当施加正向电场时，如图3B所示，压电器件伸长，在对应的柔性屏的相应位置，柔性屏难以被按下，从而产生硬的效果；当施加反向电场时，如图3C所示，压电器件缩短，在对应的柔性屏的相应位置，柔性屏就容易被按下，从而产生软的效果。进一步地，可以通过控制电场强弱来
控制压电器件的伸缩距离来实现不同等级的力反馈，从而使得压电晶体根据触觉反馈控制器14发出的控制信号在上极板31与下极板32之间施加的电压而产生形变以提供力反馈。
触觉反馈控制器14可以集成到柔性显示屏中，也可以独立于该柔性显示屏。触觉反馈控制器14接收显示屏显示的画面并进行分析。例如可以通过采用图像识别技术来识别显示画面内的各个物体，然后根据所识别出的不同物体在数据库中查找出该物体所对应的软硬程度，从而可以根据物体的不同软硬程度匹配不同的力反馈等级，并将该力反馈等级储存在触觉反馈控制器14的寄存器中以做好触觉反馈准备。当用户进行触摸操作时，该触觉反馈控制器14根据接收到触摸区域的坐标信息，开启对应位置的力反馈，并在用户触摸结束后关闭力反馈。该触觉反馈控制器14可以是带数据处理功能和信号控制功能的电子硬件。在显示画面更新后，触觉反馈控制器14重新分析力反馈等级，并更新寄存器。例如，当显示物体为杯子时，对应的力反馈比较大，这样，柔性显示屏难以按下，人就会感觉到杯子是硬的；当显示物为棉花时，对应的力反馈比较小，甚至可以是相反方向的，这样柔性显示屏就容易按下，人就会感觉到棉花软软的。当然，用户也可以关闭此功能，实现选择性的开启此功能。
图4示出了根据本发明实施例的触觉反馈方法，其包括如下步骤：
步骤S1：分析显示屏的显示画面。可以通过采用图像识别技术来识别显示画面内的各个物体，然后根据所识别出的物体在数据库中查找出各个物体所对应的物理特性，例如软硬度、温度等，从而可以根据各个物体的不同物理特性匹配不同的反馈等级。例如，当物体较硬时，提供较大的力反馈，较软时，提供较小甚至相反的力反馈；当物体温度较高时，提供较高温度的热反馈，温度较低时，提供较低温度的热反馈。
步骤S2：接收用户触摸操作的位置信息，并根据用户触摸的位置发出相应的控制信号。当用户触摸屏幕时，即可以接收到触摸输入的坐标信息，并根据用户触摸位置所对应的物体发出相应的控制信号。
步骤S3：根据控制信号，对用户触摸的位置提供相应的反馈。
步骤S4：当用户结束触摸时关闭反馈。
以上通过具体实施例描述了根据本发明的触觉反馈系统和触觉反馈方法，通过采用该触觉反馈系统和触觉反馈方法增强了触摸装置的体验感，可以让用户得到触碰真实物体的体验感，进而提升了用户体验度。本领域技术人员应当
理解本发明不仅限于物体软硬度、温度等真实感受，还可以适用于包括物体其他物理特性的真实感受。本发明还可以应用于虚拟键盘中，以实现物理按键的触控感受。
本发明进一步提供了一种显示装置，其包括如上所述的触觉反馈系统。该显示装置可以为手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
以上实施方式仅用于说明本公开，而并非对本公开的限制，有关技术领域的普通技术人员，在不脱离本公开的精神和范围的情况下，还可以做出各种变化和变型，因此所有等同的技术方案也属于本公开的范畴，本公开的专利保护范围应由权利要求限定。
