Method and device for attaching polarizer

Abstract

The invention relates to a method and a device for attaching a polarizer. The device comprises absorption equipment, supporting equipment and power equipment, wherein the absorption equipment is used for absorbing first equipment; the supporting equipment is used for placing second equipment; an absorption plane of the absorption equipment is parallel to a supporting plane of the supporting equipment; the power equipment controls the absorption equipment and/or the supporting equipment to perform relative motion along the direction which is perpendicular to the absorption plane and the supporting plane, so the first equipment and the second equipment are attached; the first equipment is the polarizer and the second equipment is a liquid crystal display panel; and or the first equipment is the liquid crystal display panel and the second equipment is the polarizer. The method and the device for attaching the polarizer is characterized in that the uniformity of pressure applied to every area of the polarizer to be attached is easy to control, and the consistency of stress applied by the polarizer to be attached on the liquid crystal display panel in the X axis direction and the Y axis direction can be ensured.

Description

technical field [0001] The invention relates to a polarizer attaching technology, in particular to a polarizer attaching method and device, and belongs to the field of liquid crystal display manufacturing.
