进一步地，所述承载台130设置有多个真空吸嘴132，承载台130通过该多个真空吸嘴132吸附固定彩膜基板120。
进一步地，上述承载台130的实施例中，所述振动机构131具体用于：驱动彩膜基板120沿垂直于彩膜基板120平面的方向振动；或在与彩膜基板120平面平行的一平面内沿两相互垂直的方向交替驱动彩膜基板120振动。参见图2，图2是通过本发明的液晶涂布装置进行液晶122涂布后的彩膜基板120的结构示意图。若其中一个振动方向为东西方向，则另一振动方向为南北方向。本实例中，通过在所述平面内沿两相互垂直的方向交替驱动彩膜基板120振动的方式，可以保证彩膜基板120在水平各方向振动一致，使液晶122向四周扩散的保持一致，从而达到快速扩散均匀的效果。
本发明所提供的承载台130实施例，通振动机构131驱动彩膜基板120持续振动，可使液晶122能够快速扩散均匀，保证了产品的显示性能，缩短了液晶涂布工艺所用的时间，从而提高了产品的生产效率。
参见图5，图5提出本发明一种液晶涂布方法的一实施例。该液晶涂布方法具体包括：
步骤S101、将液晶喷在彩膜基板上；
步骤S102、驱动彩膜基板持续机械振动，使涂布于彩膜基板内的液晶快速扩散均匀。
本实施例中，在液晶涂布组件对彩膜基板进行液晶涂布完毕之后，立即通过控制机构控制开启振动机构，使振动机构驱动彩膜基板持续机械振动，从而可以使彩膜基板内已涂布的液晶在彩膜基板的振动下快速扩散均匀。另外，在对彩膜基板进行液晶涂布之前，通过真空吸嘴将彩膜基板吸附固定在承载台上，然后通过液晶涂布组件进行液晶涂布，其中具体的液晶涂布方式是现有技术中常用涂布技术，即通过喷头的喷嘴将液晶喷至彩膜基板（框胶所围的范围内）上。
进一步地，上述液晶涂布方法实施例中，所述驱动彩膜基板持续机械振动具体为：驱动彩膜基板沿垂直于彩膜基板平面的方向振动；或在与彩膜基板平面平行的一平面内沿两相互垂直的方向交替驱动彩膜基板振动。参见图2，图2是通过本发明的液晶涂布装置进行液晶122涂布后的彩膜基板的结构示意图。在与彩膜基板平面平行的一平面内沿两相互垂直的方向交替驱动彩膜基板振动时，若其中一个振动方向是东西方向，则另一振动方向为南北方向。本实例中，通过在所述平面内沿两相互垂直的方向交替驱动彩膜基板振动的方式，可以保证彩膜基板在水平各方向振动一致，使液晶向四周扩散的保持一致，从而达到快速扩散均匀的效果。
进一步地，上述液晶涂布方法实施例中，还包括如下处理：在彩膜基板内液晶涂布完毕后，监测彩膜基板内的液晶是否均匀；如果均匀，则停止驱动彩膜基板振动；如果不均匀，则继续驱动彩膜基板振动。即在彩膜基板内地液晶涂布完毕后，通过监测机构对彩膜基板内的液晶状态进行监测。当监测到彩膜基板内的液晶处于均匀状态，则发送信息给控制机构，通知控制机构控制关闭振动机构。当监测到彩膜基板内的液晶处于非均匀状态，不发送信息，此时控制机构则控制维持振动机构的开启状态。
本发明所提供的液晶涂布方法实施例，采用在液晶涂布完毕之后，控制开启振动机构，使振动机构驱动彩膜基板持续振动，当液晶处于均匀状态时，控制关闭振动机构的方式，使液晶能够快速扩散均匀，保证了产品的显示性能，缩短了液晶涂布工艺所用的时间，从而提高了产品的生产效率。
应当理解的是，以上仅为本发明的优选实施例，不能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。
