Description

Technical Field

[0001] The utility model relates to the field of polarizer detection, in particular to a polarizer detection device. Background Art

[0002] The full name of polarizer is polarizing light film. The imaging of liquid crystal displays must rely on polarized light. All liquid crystals have two polarizing light films in front and behind, which are tightly attached to the liquid crystal glass, forming a liquid crystal film with a total thickness of about 1mm. If any polarizer is missing, the liquid crystal film cannot display images. With the continuous improvement of display manufacturing technology, foreign display manufacturers have gradually introduced automated production lines into screen manufacturing. Domestic screen manufacturers have also increased their investment in recent years and continuously carried out industrial transformation and upgrading, replacing traditional manual assembly production lines with automated production lines. In the process of polarizer lamination and upgrading to automated production lines, the problem of rapid detection of polarizer quality needs to be solved. Manual detection is inefficient and cannot keep up with the production efficiency of automated production lines.
