Description

交互平板、边框总成和触控组件 技术领域
本申请涉及显示设备领域，特别涉及一种交互平板、边框总成和触控组件。
背景技术
现有的交互平板中，一般具有由四个触控边框依次首尾相连围成的四边形边框总成，边框总成中触控电路板通常需要延伸到四边形边框总成的转角处以确保前述转角处的触控信号质量。
但是这也就导致了部分相邻两个触控边框在装配触控组件时存在干涉，从而使得装配人员需要预先拆卸其中一侧的触控边框，待其余触控边框内的触控组件装配完成后，再将该侧的触控边框装配触控组件重新安装回去，工序繁琐，成本较高，并且边框总成多次拆装易导致其内的触控组件移位，从而导致触控不准确，造成用户体验降低。

通过上述方案，在交互平板的常用状态下，触控电路板的重力主要集中在限位部上，从而降低限位件和触控电路板的粘接处的受力，进而减少限位件和触控电路板的粘接处脱离的可能性，提高产品质量。
可选的，所述侧边框中的滤光条位于所述上边框中的滤光条和所述下边框中的滤光条之间，所述侧边框中的滤光条的两端分别与所述上边框中的滤光条的侧面和所述下边框中的滤光条的侧面抵接。

交互平板是一种具有触摸屏技术的设备，用户可以通过手指或者特殊的触控笔与其进行交互操作。常见的交互平板通常有电阻式触摸屏、电容式触摸屏和红外线技术触摸屏等。以红外线技术触摸屏为例，红外线技术触摸屏是由装在触摸屏边框上的红外线发射与接收感测元件构成的一种交互式屏幕，在屏幕表面上，形成红外线探测网，任何触摸物体可改变触点上的红外线而实现触摸屏操作。
现有的红外线技术触摸屏，一般具有由四个触控边框依次首尾相连围成的四边形边框总成，边框总成中的触控电路板通常需要延伸到四边形边框总成的转角处以确保前述转角处的触控信号质量。
例如，左右边框中触控组件的触控电路板长度大于滤光条的长度，并且左右边框中触控组件的触控电路板通过位于所在边框的两端限位部抵接限位，触控电路板的两端从滤光条的两端敞口伸出，从而延伸至触摸屏的角落，进而保证转角处的触控信号质量。但是，在装配时，左右边框的触控组件的长度要远大于上下边框的触控组件之间距离，同时受限于所在边框两端限位部的阻挡，使得触控组件无法采用斜插入的方式安装在对应边框内。如此一来，左右边框中的触控组件与上下边框中的触控组件在装配时存在装配干涉，而无法完成装配操作。
现有的方式是操作人员将原组装在一起的边框总成(一般情况下边框总成的加工及出货多为一体出货)的下边框进行拆卸，然后对上边框和左右边框的触控组件进行装配，其中，左右边框中触控电路板的两端与所在边框的两端限 位部抵接限位，最后对下边框的触控组件进行装配，并将装配后的下边框重新安装回原位。
显然，上述的方式需要额外对下边框进行拆卸并重新组装，工序繁琐，并且下边框的拆卸后组装，装配间隙难以控制，易出现加大间隙等不良率问题发生，并且边框总成多次拆装易导致其内的触控组件移位，即触控感应位置偏移，从而导致触控不准确，造成用户体验低。此外，由于下边框为长条结构，在装配时，一个人往往无法顾及两端组装到位，滤光条会脱离，还有下边框和左右边框装配时，需要挪动边框调整组装间隙，一个人无法完成，这也就导致需要多人进行配合操作，劳动力需求量较大，制造成本较高。
为解决上述需要拆卸边框方能完成装配的问题，本申请发明人曾试图将左右边框的一端的限位部均做成可拆卸结构。以左边框为例，在装配时，将左边框的一端限位部拆卸下来，然后空出让位空间，以使得左边框的触控组件可以通过斜插入然后旋转的方式安装在左边框内，从而无需拆卸下边框。虽然，其无需拆卸下边框，但是仍需要拆卸限位部，并在装配后再将限位部安装回去，同样影响生产效率。并且，在左边框的触控组件安装在左边框内时，触控组件与左边框一端的空隙过小，不便于工作人员调节左边框内的触控电路板的位置以使得触控电路板可以移动至与另一端的限位部抵接，从而空余出拆卸后的限位部的安装位置，操作不便。
基于此，本申请则是通过改变现有的左右边框(侧边框)中触控组件内的触控电路板限位方式，具体的，触控电路板通过与其一端的限位部抵接，以及和触控电路板侧面连接的限位件与压块抵接的方式，实现对触控电路板的限位。相比于现有的通过触控电路板的两端分别与侧边框两端的限位部抵接限位的方式，本申请所采用的方案中侧边框的另一端则无需设置限位部，从而留出让位空间，以使得触控组件的另一端可以通过斜插入让位空间，然后触控组件整体向侧边框一侧旋转的方式安装在侧边框内，进而可以在不拆卸边框总成前提下，实现触控组件的装配。如此一来，操作人员可以在不拆卸边框总成前提下，实现触控组件的装配，避免边框总成因多次拆装导致安装在其内的触控组件位置发生偏移而影响触控精度，提高用户触控体验。同时，由于滤光条的侧面开设装配孔，在触控组件整体向侧边框一侧旋转安装在侧边框内时，可以便于操作人员穿过装配孔将触控电路板向限位部一端调节移动以使得触控电路板的一端与限位部抵接，方便用户操作。
下面将结合附图，对本申请实施方式中的技术方案进行清楚、完整地描述。显然，本申请所描述的实施方式仅仅是本申请一部分实施方式，而不是全部的实施方式。基于本申请中的实施方式，本领域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方式，都属于本申请保护的范围。
本申请提供一种交互平板，该交互平板将红外触摸控制与显示功能合二为一。具体而言，红外触摸控制功能是通过在交互平板边框上安装的红外线发射与接收感测元件实现的，这些元件在屏幕表面，共同形成了红外线探测网，当任何触摸物体接触屏幕时，都能够改变触点上的红外线，从而实现触摸屏操作。需要明确的是，本申请所涉及的交互平板可包括但不限于商业显示屏、会议显示屏、触摸一体机、自助终端机、人机交互平板、电视机以及智慧黑板等各类交互平板。
请一并参见图1至图4，在一种可实现的实施方式中，交互平板至少可以包括触控边框。触控边框具有容纳槽110和限位部120，限位部120位于容纳槽110的一端。在本实施方式中，容纳槽110应该沿触控边框的长度方向延伸设置，容纳槽110具有开口，以使得容纳于容纳槽110内的部分部件可以通过开口安装进容纳槽110内，并且容纳于容纳槽110内的部分部件可以尽可能的布满触控边框的整个长度方向。限位部120用于与容纳于容纳槽110内的部分部件抵接，从而对容纳槽110内的部分部件进行限位。
在实际应用中，触控边框作为支撑部件，主要用于对其内部的零件或部件起到支撑和保护的作用。限位部120可以通过折弯等方式与触控边框一体成型而成，当然，其也可以通过分体设计后再连接至触控边框上，本申请对此不作具体限定。
需要指出的是，上述触控边框可以作为交互平板的左边框、右边框、上边框和下边框中的至少一个进行使用，在此不作具体限定。
上述交互平板还可以包括用于实现红外触摸感应的触控组件200。触控组件200可以包括滤光条210、触控电路板220和限位件230。其中，滤光条210嵌入在容纳槽110并沿容纳槽110的长度方向延伸设置。滤光条210具有安装腔211和装配孔212，安装腔211贯穿滤光条210相对的两端以使得其端部形成有敞口。触控电路板220可以通过其中一端的敞口安装于安装腔211内，触控电路板220能够沿安装腔211的长度方向滑动并能从两端敞口伸出。装配孔212位于滤光条210的侧面，并且装配孔212与安装腔211连通，装配孔212用于 为操作人员穿过其调整安装腔211内部触控电路板220的位置，以及为限位件230穿过滤光条210与触控电路板220连接让位。
在实际应用中，滤光条210通常选择具有良好红外透过性能的材料，如红外透明的塑料或玻璃材料，以使得滤光条210能够过滤掉可见光，只允许红外光通过，以确保红外触摸技术的正常运作。触控电路板220一般包括PCB板和红外接收器和/或红外发射器，红外接收器和/或红外发射器和PCB板电连接并朝向滤光条210的出光部位。当触控电路板220内含有红外发射器时，红外发射器发射出的红外线可以穿过滤光条210，并射向其对应(另一侧边框结构中)设置的接收组件，以使得红外线穿透对应的接收组件的滤光条210，由接收组件的红外接收器接收。当用户在交互平板的显示面进行操作时，用户遮挡住红外发射器发射的红外线，接收组件无法接收发射组件发射的红外线，该交互平板根据信号的变化可以对输入信号进行信号定位。
上述交互平板还可以包括压块300。压块300与触控边框连接，在触控电路板220的一端与限位部120抵接时，限位件230穿过装配孔212与触控电路板220连接，限位件230位于压块300和限位部120之间，并且限位件230与压块300靠近限位部120的一侧抵接，从而限制触控电路板220沿触控边框的长度方向运动的自由度。
值得一提的是，相比于现有的通过触控电路板220的两端分别与触控边框两端的限位部120抵接限位的方式，本申请中触控电路板220通过与其一端的限位部抵接，以及和触控电路板220侧面连接的限位件230与压块300抵接的方式，实现对触控电路板220的限位，改变对触控电路板220的限位方式，从而触控边框的另一端则无需设置限位部120，留出让位空间a。这样一来，可以参见图5和图6所示，触控组件200的另一端可以通过斜插入让位空间a，然后触控组件200按照整体向触控边框一侧(图5的箭头方向)旋转的方式安装在触控边框内，进而可以在不拆卸边框总成前提下，实现将触控组件200装配进容纳槽110内。如此一来，操作人员可以在不拆卸边框总成前提下，实现触控组件200的装配，从而避免边框总成因多次拆装而导致其内的触控组件200移位影响触控精度，提高触控准确性，进而优化用户使用体验。当触控组件200发生损坏时，操作人员可以先将限位件230取下，然后触控电路板220向远离限位部120的一端移动，最后再按照向远离触控边框旋转的方式从触控边框内拆除，从而使得对触控组件200的拆卸变得方便快捷，不再需要经过复杂的拆 卸过程来拆卸边框总成，节省检修、维护及更换部件所需的时间，节省了人力成本。
同时，由于滤光条210的侧面开设装配孔212，在触控组件200整体向触控边框一侧旋转安装在触控边框内时，操作人员可以穿过装配孔212将触控电路板220向限位部120的一端调节移动，以使得触控电路板220的一端与限位部120抵接，方便用户操作，提高组装效率。
上述装配孔212可以被构造为任意形状的孔位，例如圆孔、矩形孔或者三角形孔等。
以装配孔212被构造为矩形孔为例，在一种可实现的实施方式中，矩形孔应当沿着滤光条210的长度方向延伸，这样，在限位件230通过矩形孔与触控电路板220连接时，在限位件230受力方向上，可以增加限位件230与触控电路板220的连接长度，从而可以减少限位件230与触控电路板220局部应力集中的情况，提高两者之间连接的稳定性和承载能力。其中，装配孔212的长度应当大于限位件(230)的长度，和/或，装配孔212的宽度大于限位件230的宽度，从而使得装配孔212的内轮廓略大于限位件230的外轮廓，以方便操作人员将限位件230穿过装配孔212与触控电路板220连接。
上述压块300可以单独作为用于限制限位件230向远离限位部120方向移动的部件。
当然，上述压块300还可以同时作为夹持部件。为明确展示其功能，请一并参考图7至图9，在一种可实现的实施方式中，交互平板还包括待夹持件400。滤光条210具有支撑面213，待夹持件400位于支撑面213和压块300之间，支撑面213和压块300共同用于夹持待夹持件400。通过这种设计，压块300不仅能够有效阻止限位件230远离限位部120，还能与滤光条210配合，实现对待夹持件400的紧固。这种双重功能的设计，无需额外增加组件，显著降低了生产成本。
在本实施方式中，待夹持件400作为交互平板的显示侧的保护部件，用于防止交互平板的显示模组发生损伤，待夹持件400可以采用玻璃或者透明塑料材质等。在实际应用中，压块300应当与触控边框可拆卸连接，从而在安装触控组件200和待夹持件400时，压块300可以进行避让，避免压块300与触控组件200和待夹持件400的安装路径产生干涉。为了保证对待夹持件400的夹持稳定性，压块300应当具有多个，多个压块300沿触控边框的长度方向间隔 设置，相应的，限位件230与其中一个触控边框抵接。
鉴于红外线要穿过滤光条210的一侧射出或进入，为了避免装配孔212对红外线产生影响，请再次参见图7至图9，在一种可实现的实施方式中，滤光条210还具有滤光面214和阻挡面215。支撑面213位于滤光面214和阻挡面215之间，滤光面214用于过滤触控电路板发射或接收的光线，装配孔212开设在阻挡面215上。换而言之，滤光条210上用于过滤光线的部分与用于开设装配孔212的部分分别位于不同面上，从而避免当装配孔212内安装限位件230时，限位件230对红外线产生遮挡，提高触控精准性。
在实际应用，滤光面214、支撑面213和阻挡面215由滤光条210在注塑挤出时一体成型而成，滤光面214和支撑面213为滤光条210上向内侧面延伸的部分形成，滤光面214与触控电路板220上的红外发射器和/或红外接收器相对应，以使得所发射或接收的红外线可以穿过滤光面214后传输。
请参见图7所示，在一种可实现的实施方式中，安装腔211的内壁形成有滑槽216。滑槽216沿安装腔211的长度方向延伸，触控电路板220卡设在滑槽216内，以由滑槽216限制触控电路板220沿安装腔220的长度方向滑动，从而限定触控电路板220的滑动方向，并且限位部120位于触控电路板220的滑动方向上，这样，可以限定沿滑槽216滑动的触控电路板220必然可以与位于安装腔220一端的限位部120抵接。同时，滑槽216还可以使得触控电路板220始终处于直立状态，防止触控电路板220在滑动过程中发生偏移，从而保证交互平板的触控精度，提高交互体验。
在本实施方式中，滑槽216可以具有两个，两个滑槽216位于安装腔220的顶面和底面并且相对设置，触控电路板220在两个滑槽216的限制下平稳滑动。在实际应用中，滑槽216可以是安装腔220内壁上向外侧凹陷的凹槽结构。当然，滑槽216也可以是安装腔220内壁向内凸起的两个凸块围绕形成，本申请对此不作具体限定。
在一种可实现的实施方式中，限位件230与触控电路板220粘贴连接。安装时，操作人员只需要将限位件230穿过装配孔212并朝向触控电路板220一侧按压即可实现连接，操作简单，方便安装操作。当然，上述限位件230也可以与触控电路板220采用其他连接方式，例如，触控电路板220上安装有卡扣或卡槽，限位件230通过与卡扣或卡槽卡接的方式与触控电路板220连接等，本申请对此不作具体限定。
在实际应用中，限位件230应当具有一定的硬度，以在限位件230与压块300抵接时，避免限位件230发生变形移动。其中，限位件230可以采用泡棉、橡胶块或塑料块等。
交互平板的整体结构通常由显示模组和边框总成构成，边框总成围绕在显示模组的外沿，并用于显示模组的外延形状相匹配。边框总成通常由多段边框依次相连并围合构成，上述触控边框则为边框总成的其中一段边框，每段边框与其相对应的显示模组的侧边相匹配。具体的，每段边框的长度会比与之对应的显示模组的侧边的长度略长或略短，当每段边框略短于对应的侧边时，相邻两个边框间可通过转角件等连接部件实现连接，当每段边框略长于对应的侧边时，相邻两个边框间可通过焊接或通过一段钣金件直接辊压、折弯等方式形成一体式结构。
在一般情况下，显示模组在正面上的正投影形状可以为四边形，当然也不限于其他形状。相应的，边框总成所围合成的形状也可以为四边形或者其他形状环状结构。其中，本申请所定义正面是指，交互平板在使用状态下，正对着用户的一面，反之则为反面。
以边框总成围合形成四边形环状结构为例，边框总成以单段式结构、一体式结构或者至少部分一体式结构围设在显示模组的外周。具体的，请再次参见图1所示，在一种可实现的实施方式中，上述触控边框作为侧边框100使用。交互平板还包括上边框500和下边框600，侧边框100具有两个，两个侧边框100相对设置，上边框500和下边框600相对设置，上边框500、下边框600和两个侧边框围绕形成四边形环状结构。
在本实施方式中，以图1视角下的交互平板为例，上边框500位于交互平板的上方，下边框600位于交互平板的下方，两个侧边框100分别位于交互平板的左右两侧。优选的，边框总成围合成的四边形环状结构为矩形环状结构。需要指出的是，边框总成围合形成矩形环状结构，可以有效地固定交互平板的各个部分，提供更好的结构支撑和稳定性，防止其在使用过程中出现晃动或变形。此外，这种设置所形成的交互平板为矩形结构，有利于整体外观的美观性。后续，也将以边框总成为矩形环状结构进行阐述。
在实际应用中，两个侧边框100内分别均安装有触控组件200，其中一侧边框100内的触控电路板220用于发射红外信号，另一侧边框100内的触控电路板220内用于接收红外信号，从而在屏幕表面上形成X方向的红外线探测网。 同理，上边框500和下边框600内也分别安装有触控组件，并且两者之一用于发射红外信号，两者另一用于接收红外信号，从而在屏幕表面上形成Y方向的红外线探测网。
为了在侧滤光部件200安装在容纳槽110时，仍方便操作人员穿过操作孔212对侧触摸框220进行调节，请再次参见图3所示，在一种可实现的实施方式中，矩形环状结构具有内侧面和外侧面，上述容纳槽110的开口朝向内侧面，侧滤光条210通过开口嵌入在容纳槽110内，操作孔212位于侧滤光条210靠近内侧面的一侧。这样，在侧滤光条210安装在容纳槽110时，操作孔212可以从开口处外露，从而无需将侧滤光条210取出即可对侧滤光条210内部的侧触摸框220进行调节操作。
上述限位部120可以位于容纳槽110靠近下边框600的一端，限位部也可以位于容纳槽110靠近上边框500的一端。
但鉴于交互平板在多数情况下均呈竖直状态，这也使得交互平板内的部件在重力的作用下大部分时间存在朝向下边框600一侧的作用力。如此一来，倘若上述限位部120位于容纳槽110靠近上边框500的一端，在交互平板呈竖直状态时，限位部120位于触控电路板220的上方，限位部120对触控电路板220不存在支撑受力，触控电路板220的重力主要集中在限位件230和触控电路板220的粘接处，这对粘接处的粘结力要求较大，长此以往，势必会导致限位件230与触控电路板220脱离，从而致使触控电路板220向下移动。
为了解决上述问题，本申请优选采用上述限位部120位于容纳槽110靠近下边框600的一端，这样，在交互平板呈竖直状态时，限位部120位于触控电路板220的下方，触控电路板220的重力主要集中在限位部120上，如此，减少限位件230和触控电路板220的粘接处脱离而导致触控电路板220移位的可能性，保证交互平板的触控信号位置准确性，提高产品质量。
在实际应用中，限位部120应当位于下边框600中滤光条的延长线上，这样，触控电路板220的底端也就可以延伸至下边框600中的滤光条处，使得触控电路板220可以尽可能延伸到交互平板的角落位置，保证角落位置红外信号的质量。
关于侧边框100中滤光条210的限位方式，请再次参见图2和图3所示，在一种可实现的实施方式中，侧边框100中的滤光条210位于上边框500中的滤光条和下边框600中的滤光条之间，侧边框100中的滤光条210的两端分别 与上边框500中的滤光条的侧面和下边框600中的滤光条的侧面抵接，从而无需额外设置限位结构，即可使得滤光条210实现准确的限位，降低成本。
在实际应用中，上边框500和下边框600可以在各自的两端分别设置限位结构，从而利用各自两端的限位结构对其内的滤光条210和触控电路板220实现限位，进而在上边框500和下边框600中的滤光条宽度不变的情况下，依靠上边框500和下边框600中的滤光条的侧面限位的侧边框100中的滤光条210亦可实现准确限位。
为了方便理解本申请在不拆卸边框总成前提下，实现触控组件200的装配的方案，本申请提供了具体装配操作步骤如下：
步骤一：将触控电路板220分别装入对应的滤光条210的安装腔211内，形成触控组件200。
步骤二：将上边框500对应的触控组件200装配入上边框500中，并利用上边框500两端的限位结构进行限位；将下边框600对应的触控组件200装配入下边框600中，并利用下边框600两端的限位结构进行限位。
步骤三：将侧边框100对应的触控组件200的一端倾斜插入侧边框100靠近上边框500的一端内，使侧边框100对应的触控组件200的一端置于让位空间a内，并滑动触控电路板220，并确保触控电路板220未从滤光条210的另一端敞口伸出。
步骤四：将侧边框100对应的触控组件200的另一端按照图5所示的箭头方向推入侧边框100的容纳槽110内，以使触控组件200完全装入侧边框100内。
步骤五：调节侧边框100内的滤光条210的位置，使得滤光条210的两端分别与上边框500和下边框600中的滤光条210侧面抵接限位。
步骤六：通过装配孔212将侧边框100内的触控电路板220向限位部120方向推抵，以使得触控电路板220与限位部120抵接；并在侧边框100内的触控电路板220上贴附限位件300，使得限位件300从装配孔212伸出延伸至滤光条210的外部。
步骤七：将待夹持件400放置到支撑面213上，在侧边框100上装配压块300，由压块300与支撑面213配合夹紧待夹持件400，以固定待夹持件400；同时，压块300远离限位部120的一侧与限位件300抵接，以由限位部120和压块300配合限位件400共同对侧边框100内的触控电路板220进行限位。
基于相同的发明构思，本申请还提供另外一种交互平板，该交互平板至少可以包括侧边框100和触控组件200，其中，侧边框100具有容纳槽110和限位部120，限位部120位于容纳槽110的一端。触控组件200可以包括滤光条210、触控电路板220和限位件230，滤光条210嵌入在容纳槽110内，滤光条210具有安装腔211和装配孔212，触控电路板220安装于安装腔211内并能够沿安装腔211的长度方向滑动，装配孔212位于滤光条210的侧面并与安装腔211连通。在触控电路板220的一端与限位部120抵接时，限位件230通过装配孔212与触控电路板220连接，并且限位件230与装配孔212远离限位部120的侧面抵接。
通过上述方案，触控电路板220通过与其一端的限位部120抵接，以及和触控电路板220侧面连接的限位件230与装配孔212远离限位部120的侧面抵接的方式，实现对触控电路板220的限位，改变对触控电路板220的限位方式，从而侧边框100的另一端则无需设置限位部120，留出让位空间a，进而可以在不拆卸边框总成前提下，实现将触控组件200装配进容纳槽110内。如此一来，操作人员可以在不拆卸边框总成前提下，实现触控组件200的装配，从而避免边框总成因多次拆装而导致其内的触控组件200移位影响触控精度，提高触控准确性，进而优化用户使用体验。同理，当触控组件200发生损坏时，也不再需要经过复杂的拆卸过程来拆卸边框总成，节省检修、维护及更换部件所需的时间，节省了人力成本。同时，本方案相较于上述提供触控电路板220的限位方式，限位件230无需与压块300侧面相抵接，从而装配孔212和压块300的安装位置也无需相绑定，减少加工难度。
优选的，交互平板还包括上边框500和下边框600。上述侧边框100具有两个，两个侧边框100相对设置，上边框500和下边框600相对设置，上边框500、下边框600和两个侧边框100围绕成矩形环状结构。滤光条210位于上边框500中的滤光条210和下边框600中的滤光条210之间，滤光条210的两端分别与上边框500中的滤光条210的侧面和下边框600中的滤光条210的侧面抵接。
需要指出的是，关于侧边框100、触控组件200、限位件230、上边框500和下边框600的具体结构可以参照上述实施方式中的内容，在此不再赘述。
基于相同的发明构思，本申请还提供一种边框总成，该边框总成至少可以包括上边框500、下边框600和两个侧边框100，其中，上边框500和下边框600相对设置，两个侧边框100相对设置，上边框500、下边框600和两个侧边框围 绕形成四边形环状结构。侧边框100具有容纳槽110和限位部120，限位部120位于容纳槽110的一端，容纳槽110的另一端设有让位空间a。
通过上述方案，触控组件200可以利用容纳槽110另一端的让位空间a，在不拆卸边框总成前提下，实现将触控组件200装配进容纳槽110内。如此一来，操作人员可以在不拆卸边框总成前提下，实现触控组件200的装配。同理，当触控组件200发生损坏时，也不再需要经过复杂的拆卸过程来拆卸边框总成，节省检修、维护及更换部件所需的时间，节省了人力成本。
需要指出的是，关于侧边框100、限位部120、上边框500和下边框600的具体结构可以参照上述实施方式中的内容，在此不再赘述。
基于相同的发明构思，本申请还提供一种触控组件200，该触控组件200至少包括滤光条210、触控电路板220和限位件230，其中，滤光条210具有安装腔211和装配孔212，安装腔211贯穿滤光条210的两端，装配孔212位于滤光条的侧面并且装配孔212与安装腔211连通。触控电路板220安装于安装腔211内，并且触控电路板220能够沿安装腔211长度方向滑动。限位件230与触控电路板220连接，并且限位件230穿过装配孔212延伸至安装腔211外部。
通过上述方案，触控电路板220通过在其侧面连接的限位件230，利用限位件230实现至少一个方向的限位，改变了现有对触控电路板220两端限位的方式，本申请触控电路板220至少存在一端无需设置限位件230，从而留出让位空间a，进而可以在不拆卸边框总成前提下，实现将触控组件200装配进容纳槽110内。
在本实施方式中，触控组件200可以用于装配在侧边框100内，也可以装配在上边框500和下边框600内，本申请对此不作具体限定。其中，滤光条、触控电路板220和限位件230的具体结构，可以参照上述实施方式中滤光条210、触控电路板220和限位件230的内容，在此不再赘述。
