一方面，本发明提供一种液晶面板之间隔物的制造方法，请参阅图1和图2，图1和图2分别表示制造间隔物过程中的两个状态的示意图。液晶面板之 间隔物的制造方法包括如下步骤：
提供一个基板10和一个制造间隔物的设备，所述制造间隔物的设备包括喷嘴20、驱动单元(未图示)和固化单元40，所述喷嘴20内注入光阻材料30，所述喷嘴20和所述固化单元40位于所述基板10的正上方，所述驱动单元用于驱动所述喷嘴20移动；所述基板10可以为玻璃基板或陶瓷基板，具体在液晶显示面板中，所述基板10可以为CF基板或TFT基板。

所述制造间隔物的设备还包括测量单元(未图示)，所述测量单元连接至所述喷嘴20，所述测量单元用于测量所述间隔物相对所述基板10垂直突出的高度。所述测量单元可以为激光检测单元，通过光发射器和光接收器所采集的信号，计算出已经固化的间隔物的高度。
所述制造间隔物的设备还包括报警单元(未图示)，所述报警单元用于接收所述测量单元传送的信号，当所述测量单元测量到的所述间隔物的高度大于等于所述预设的高度时，所述测量单元发送信号给所述报警单元，所述报警单元传送信号给所述控制单元，所述控制单元控制所述喷嘴20停止工作。
所述制造间隔物的设备还包括磨削装置(未图示)，当所述测量单元测量到的所述间隔物的高度大于所述预设的高度时，启动所述磨削装置，磨削所述间隔物，使得所述间隔物的高度等于所述预设的高度。
本发明通过制造间隔物的设备的喷嘴20滴落光阻材料30，通过固化单元40将滴落至基板10上的光阻材料30固化，通过喷嘴20与固化单元40重复循环的工作，使得所述光阻材料在所述基板10上层层堆叠，直至形成预设高度间隔物。这样制造技术形成的间隔物有利于节约光阻材料，所利用的光阻材料无需要浪费，具有节能环保的优势。
由于基板10上的间隔物呈阵列分布，所述制造间隔物的设备也可以设置多个阵列排布或排成一行的喷嘴20，每个喷嘴20上都设固化单元40，可以同时制造多个间隔物，具体的做法与制作单个的间隔物的方法相同，不再描述。
以上所述是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
