Problems solved by technology

The existing filling method of the flexible liquid crystal cell adopts the traditional filling method. On the one hand, the substrate of the flexible liquid crystal cell is a flexible material (PET, PC, etc.), and the inner and outer surfaces of the flexible liquid crystal cell will be A certain pressure difference (the internal pressure of the liquid crystal cell is greater than the external pressure) will cause the liquid crystal cell to bulge, or the flexible liquid crystal cell will be cracked and damaged, which will greatly reduce the production yield; It leads to long pouring time, poor filling effect, low yield rate, and increases production cost

Embodiment 1

[0090] Before filling the crystal, pressurize the surface of the flexible liquid crystal cell by 0.03Mpa, and then put the filling port downward into the filling basket. The filling port of the flexible liquid crystal cell is placed on the tray downwards, so that the filling bar and the filling port correspond to a straight line, and the liquid crystal cell and the liquid crystal are heated at the same time, and the heating temperature is 50°C, and then the door of the filling machine is closed for vacuuming Operation, the vacuum degree is set to 3pa. Make the filling port of the flexible liquid crystal cell fully contact with the liquid crystal; then inflate the inside of the filling machine with an air pressure of 1 atmosphere, and use the air pressure to press the liquid crystal from the filling port into the inside of the flexible liquid crystal cell, and let it stand still after the inflation is completed , keep the temperature at 50°C.

Embodiment 2

[0092] Before filling, pressurize the surface of the flexible liquid crystal cell by 0.04Mpa, and then put the filling mouth downwards into the filling basket. The filling port of the flexible liquid crystal cell is placed downwards on the tray, so that the filling bar and the filling port correspond to a straight line, and the liquid crystal cell and the liquid crystal are heated at the same time, the heating temperature is 55°C, and then the door of the filling machine is closed for vacuuming Operation, the vacuum degree is set to 5pa. Make the filling port of the flexible liquid crystal cell fully contact with the liquid crystal; then inflate the inside of the filling machine with an air pressure of 2 atmospheres, press the liquid crystal from the filling port into the inside of the flexible liquid crystal cell by air pressure, and let it stand still after the inflation is completed , keep the temperature at 55°C.

Abstract

The invention discloses a crystal-filling device and a crystal-filling method of a flexible liquid crystal cell. The crystal-filling device includes a clamp, and the clamp clamps a flexible liquid crystal cell to be filled and produces Uniform surface pressure. Before the filling machine is evacuated, a uniform surface pressure is generated on the surface of the flexible liquid crystal cell by using a fixture to heat the liquid crystal to reduce the viscosity of the liquid crystal. balance, and then fill the crystal with gas, so that the pressure difference between the inside and outside of the flexible liquid crystal cell can be avoided during the vacuum process, and the liquid crystal cell can be avoided from swelling and cracking. The crystal filling device of the flexible liquid crystal cell and the crystal filling method thereof of the present invention solve the problem that the liquid crystal cell is bulged, cracked and damaged due to the pressure difference generated on the inner and outer surfaces of the flexible liquid crystal cell during the vacuuming process of filling the crystal, and the productivity is low, and the production cost.

Description

technical field [0001] The invention relates to the technical field of flexible liquid crystal displays, in particular to a crystal filling device and a crystal filling method for a flexible liquid crystal cell, which are suitable for the preparation process of flexible liquid crystal devices. Background technique [0002] At present, the filling method of the liquid crystal cell prepared by using glass as the substrate is very mature, and the liquid crystal cell with excellent effect and production yield can be obtained. The existing filling method of the flexible liquid crystal cell adopts the traditional filling method. On the one hand, the substrate of the flexible liquid crystal cell is a flexible material (PET, PC, etc.), and the inner and outer surfaces of the flexible liquid crystal cell will be A certain pressure difference (the internal pressure of the liquid crystal cell is greater than the external pressure) will cause the liquid crystal cell to bulge, or the fle...
