Liquid crystal glass production workshop and FFU control method in workshop

The invention discloses a liquid crystal glass production workshop. The liquid crystal glass production workshop comprises a production region and a manual operating region located behind the production region, wherein the production region comprises a glass cutting region, a glass detection region and a glass packaging region that are arranged in a row; a glass transmission line crossing the glass cutting region, the glass detection region and the glass packaging region is arranged in the production region; pieces of operating equipment for operating glass are further arranged in the glass cutting region, the glass detection region, the glass packaging region and the manual operating region; a fan filter unit is arranged above the pieces of operating equipment in the the glass cutting region, the glass detection region, the glass packaging region and the manual operating region, so that the air pressures of the the glass cutting region, the glass detection region, the glass packaging region and the manual operating region are sequentially reduced. The production workshop disclosed by the invention is low in cost and high in environmental purification degree. The invention further discloses a FFU control method in the workshop.
