Abstract

The invention provides a forming method for a flexible liquid crystal cell for a liquid crystal display, which includes the steps: fabricating ITO (indium-tin oxide) patterns, arranging PS (photoresist spacer) supporting columns, coating PI (polyimide) films, forming the cell, cutting, injecting, sealing, performing visual inspection or / and electrical inspection, and the like. The forming method for the flexible liquid crystal cell for the liquid crystal display utilizes the lower PS supporting columns to replace resin powder balls in an original liquid crystal cell, so that the cell thickness is supported. When the cell thickness is small, the PS supporting columns are sufficiently and fixedly adhered with the surface of a substrate and cannot be separated from the substrate to vibrate, so that noise of the liquid crystal screen is avoided.

Description

technical field [0001] The invention relates to a method for forming a liquid crystal box of a flexible liquid crystal display. Background technique [0002] Liquid crystal displays (LCDs) currently on the market are made of glass. It is to make ITO graphics on the glass substrate first, and then complete the production of LCD through the processes of orientation treatment, screen printing, powder spraying, box forming, glass cutting, liquid crystal filling, sealing, polarizer attachment, and inspection. The main production equipment includes: cleaning equipment, exposure equipment, development and etching equipment, PI coating equipment, directional friction equipment, screen printing box equipment, liquid crystal filling equipment, glass cutting equipment, etc. The manufacturing process and technology of liquid crystal displays with glass substrates are relatively mature, but due to the use of glass substrates, the finished products cannot be bent, and the light transmitt...
