其中，该支撑部、该第二挡墙和该盖板配合形成容置槽以容置并固定该液晶面板。
其中，该第二挡墙与该液晶面板的侧边之间设有缓冲材料，该盖板与该液晶面板的上表面之间设有缓冲材料，该支撑部和该液晶面板的下表面之间设有缓冲材料。
其中，该前框为多个并间隔设置。
为解决上述技术问题，本发明采用的另一个技术方案是：提供一种液晶显示装置的液晶面板对位方法，该方法采用上述框架单元，前框为多个，该方法包括：将液晶面板设于背板组件上；将多个前框的盖板压合到液晶面板的上表面，并通过多个前框的挡墙推动液晶面板到背板组件的预定位置上以实现液晶面板的对位；其中，侧板与挡墙相配合以托举液晶面板。

【具体实施方式】
下面结合附图和实施例，对本发明作进一步的详细描述。以下实施例仅用于说明本发明，但不应用来限定本发明的范围。
实施例一，请参阅图1，图1是采用本发明一实施例框架单元的液晶显示装置的部分结构示意图。
在本实施例中，该液晶显示装置包括液晶面板10和框架单元，而该框架单元包括但不限于前框11和背板组件12。
具体而言，前框11可以为一个或多个，其包括相连接的盖板111和挡墙112。盖板111抵接液晶面板10的上表面，其底面可以平行于液晶面板10的上表面设置，以达到更好的固定效果。挡墙112可以和盖板111相垂直，挡墙112弹性抵接液晶面板10的侧边，进一步而言，挡墙112可以包括第一挡墙1121、第二挡墙1122以及连接第一挡墙1121和第二挡墙1122的连接部1123。第二挡墙1122与盖板111的一端相连接；连接部1123一端与第二挡墙1122远离盖板111的一端相连接，另一端与第一挡墙1121相连接。当然，盖板111和挡墙112之间可以为焊接或一体成型，在此不作限定。前框11整体上呈阶梯状设计，具体来说，第一挡墙1121、第二挡墙1122可以沿垂直盖板111的方向设置，也可以成一定的倾斜角度设置，连接部1123可以平行盖板111设置，在此不作限定。
背板组件12包括底板121和侧板122，对应地，第一挡墙1121紧邻侧板122的侧壁设置，连接部1123紧邻侧板122的端面设置，第二挡墙1122自连接部1123往远离侧板122的方向延伸并与盖板111相连接。底板121用于支撑液晶显示装置的光学部材（图未示），侧板122可以紧邻第一挡墙1121且与第一挡墙1121相平行设置，从而与挡墙112相配合以托举液晶面板10。换而言之，可以在侧板122远离底板121的端部形成一支撑板（图未示），通过支撑板的结构直接支撑液晶面板10的下表面，并通过与挡墙112的配合限定即可实现托举液晶面板10。
当然，在其他实施例中，该框架单元还可以另外设置胶框13。具体来说，胶框13包括相连接的竖直部131和支撑部132。竖直部131夹设于第一挡墙1121和侧板122之间，竖直部131、第一挡墙1121和侧板122之间可以呈紧密配合，以加强框架单元结构的紧凑性。与前述不同之处在于，可以通过支撑部132抵接液晶面板10的下表面以替换侧板122的支撑板，即通过支撑部132与连接部1123相接触以支撑液晶面板10，以实现弹性托举液晶面板10。优选地，支撑部132、第二挡墙1122和盖板111之间形成有容置槽14，液晶面板10容置并固定于容置槽14内。
另外，本实施例还可以通过在支撑部132、第二挡墙1122、盖板111与液晶面板10之间分别设置缓冲材料15来增强对于液晶面板10的固定效果，譬如直接贴附弹性的材料，如橡胶或弹性粒子等，在此不作限定。
下面结合图1简述本实施例框架单元和液晶面板10的配合定位过程：盖板111通过缓冲材料15压住液晶面板10的上表面，支撑部132通过缓冲材料15支撑液晶面板10的下表面；液晶面板10的侧边通过缓冲材料15抵靠第二挡墙1122。由于本实施例由第二挡墙1122直接跟液晶面板10的侧边相配合，框架单元在抵靠液晶面板10处的厚度仅为第二挡墙1122的厚度，大大地减小了边框的厚度，同时，由于液晶面板10的上表面和侧边均与前框11相抵靠，通过前框11的第二挡墙1122即可推动液晶面板10到预定位置上，因此可以实现液晶面板10的精确定位，并进一步实现液晶显示装置的自动化组装。
本发明实施例框架单元的前框11上的盖板111用于弹性抵接液晶面板10的上表面，前框11上的挡墙112弹性抵接液晶面板10的侧边，实现了液晶面板10的精确定位，有利于实现液晶显示装置的自动化组装。同时，本发明实施例无需用到胶框的挡墙来对液晶面板进行水平方向的定位，从而可以减小液晶显示装置的边框的厚度，以实现超窄边框。
实施例二，请参阅图2，图2是采用本发明另一实施例框架单元的液晶显示装置的部分结构示意图。
在本实施例中，该液晶显示装置包括液晶面板20和框架单元，而框架单元包括但不限于前框21和背板组件22。
前框21包括可以相垂直设置的盖板211和挡墙212，而背板组件22包括相连接的底板221和侧板222。需要指出的是：实施例二与实施例一的区别在于，实施例二中挡墙212平行于竖直部231和侧板222设置，并不成实施例一中的阶梯状，也就是说，挡墙212并不设置为第一挡墙、第二挡墙和连接部相连接的结构。挡墙212和盖板211相互垂直设置。其他各部件结构与实施例一中各部件结构基本相同，在此不作赘述。
在本实施例中，可以在侧板222远离底板221的端部形成一支撑板（图未示），通过支撑板的结构直接支撑液晶面板20的下表面，并通过与挡墙212的配合限定即可实现托举液晶面板20。而在其他实施例中，该框架单元还可以设置胶框23来实现托举液晶面板20，譬如，胶框23包括相连接的竖直部231和支撑部232，通过支撑部232即可支撑液晶面板20的下表面，由于胶框23的结构已经在上述实施例中作了详细的说明，故在此不作赘述。优选地，支撑部232、挡墙212和盖板211之间形成有容置槽24，液晶面板20容置并固定于容置槽24内。
另外，本实施例还可以通过在支撑部232、挡墙212、盖板211与液晶面板20之间分别设置缓冲材料25来增强对于液晶面板20的固定效果，譬如直接贴附弹性的材料，如橡胶或弹性粒子等，在此不作限定。
下面结合图2简述本实施例框架单元与液晶面板20的配合定位过程：盖板211通过缓冲材料25压住液晶面板10的上表面，支撑部232通过缓冲材料25支撑液晶面板20的下表面；液晶面板20的侧边通过缓冲材料25抵靠挡墙212。由于本实施例由挡墙212直接跟液晶面板20的侧边相配合，框架单元在抵靠液晶面板20处的厚度仅为挡墙212的厚度，大大地缩小了边框的厚度，同时，由于液晶面板20的上表面和侧边均与前框21相抵靠，通过前框21的挡墙212即可推动液晶面板20到预定位置上，因此可以实现液晶面板20的精确定位，并进一步实现液晶显示装置的自动化组装。
本发明实施例框架单元的前框21上的盖板111用于弹性抵接液晶面板20的上表面，前框21上的挡墙212弹性抵接液晶面板20的侧边，实现了液晶面板的精确定位，有利于实现液晶显示装置的自动化组装。同时，本发明实施例无需用到胶框的挡墙来对液晶面板进行水平方向的定位，从而可以减小液晶显示装置的边框的厚度，从而实现超窄边框。
请进一步参阅图3a和图3b，图3a是本发明一实施例液晶显示装置的组装示意图，图3b是图3a所示的液晶显示装置组装完成的结构示意图。
如前所述，框架单元包括前框31和背板组件（未标示）。
其中，图3a和图3b中的前框31为多个且呈L型，前框31可以分布在液晶面板的侧边或多个角上并且间隔设置。优选地，前框31和液晶面板的角均为四个，即该前框31分布在液晶面板的四个角上。另外，前框31还可以为长条型以配合L型的前框31对液晶面板进行定位，在此不作限定。
本发明实施例还提供了一种液晶显示装置，该液晶显示装置包括液晶面板和上述的框架单元。其中，框架单元可以包括前框和背板组件等。如前所述，设置在前框上的盖板用于弹性抵接液晶面板的上表面，设置在前框上的挡墙弹性抵接液晶面板的侧边；设置在背板组件上的底板用于支撑液晶显示装置的光学部材，设置在背板组件上的侧板与挡墙相配合以托举液晶面板。当然，在其他实施例中，还可以设置胶框，胶框包括竖直部和支撑部，竖直部夹设于挡墙和侧板之间，支撑部抵接液晶面板的下表面。由于采用该框架单元的液晶显示装置的具体结构已经在前文中进行了详细的描述，故在此不再赘述。
请参阅图4，图4是本发明实施例液晶面板对位方法的流程示意图。本实施例液晶面板对位方法采用前面实施例所述的框架单元，框架单元包括前框和背板组件，该前框可以为一个或多个，该方法包括：
步骤S401：将液晶面板设于背板组件上。
步骤S402：将多个前框的盖板压合到液晶面板的上表面，并通过多个前框的挡墙推动液晶面板到背板组件的预定位置上以实现液晶面板的对位。
如前面实施例所述，步骤S402可以通过侧板与挡墙相配合以托举液晶面板，而在其他实施例中，若框架单元还设有胶框，则通过胶框直接支撑液晶面板的下表面，其具体配合方式已经在前面实施例中作了详细论述，在此不做赘述。
本发明实施例液晶面板对位方法通过将液晶面板设于背板组件上，将多个前框的盖板压合到液晶面板的上表面，并通过多个前框的挡墙推动液晶面板到背板组件的预定位置上以实现液晶面板的对位。本发明实施例实现了液晶面板的精确对位，有利于实现液晶显示装置的自动化组装。同时，本发明实施例无需用到胶框的挡墙来对液晶面板进行水平方向的定位，从而可以缩小液晶显示装置边框的厚度，以实现超窄边框。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
