Claim Text:
1. A device for adjusting post-spacer height in production of liquid crystal displays (LCD), comprising a controller and an extrusion panel, wherein the controller is configured to control the extrusion panel to perform plastic deformation treatment on post spacers and acquire height values and coordinate values of the post spacers on the substrate, of which the heights are more than the predetermined height value; the extrusion panel is configured to perform plastic deformation treatment on the post spacers on a substrate, of which heights are more than a predetermined height value, according to the height values and the coordinate values of the post spacers acquired by the controller, under the control of the controller after a rubbing process and before a cell assembly process, so that the standard deviation of the post-spacer height on a substrate can fall in a range of a predetermined standard deviation required to be achieved by products; and the extrusion panel further comprises a support table and a plurality of extruding rods which are separately actuated on the support table.
