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 pouring the crystal, press 0.03Mpa on the surface of the flexible liquid crystal cell, and then put the pouring port down into the pouring basket. When pouring the crystal, add the liquid crystal to the crystal strip in the tray of the crystal pouring machine, so that it is inserted in the pouring basket Place the crystal filling port of the flexible liquid crystal box downward on the tray, so that the crystal filling bar and the crystal filling port are in a straight line. The liquid crystal cell and the liquid crystal are heated at the same time, and the heating temperature is 50℃, and then the crystal filling machine door is closed and vacuumed Operation, the vacuum degree is set to 3pa. Make the crystal filling port of the flexible liquid crystal cell fully contact the liquid crystal; then inflate the inside of the crystal filling machine with a gas pressure of 1 atmosphere. Use the air pressure to press the liquid crystal from the crystal filling port into the...

Abstract

The invention discloses a crystal pouring device and method for a flexible liquid crystal cell. The device comprises a clamp, wherein the clamp is used for clamping the flexible liquid crystal cell into which crystal is to be poured and generating even surface pressure on the flexible liquid crystal cell. Before a crystal pouring machine is vacuumized, even surface pressure is generated on the surface of the flexible liquid crystal cell by means of the clamp, and liquid crystal is heated to reduce the viscosity of the liquid crystal. After the crystal pouring machine is vacuumized, the crystal pouring machine is in a pressure maintaining state to enable the interior vacuum degree of the flexible liquid crystal cell to be balanced, and then crystal pouring and inflation are conducted, so that pressure difference is prevented from being generated between the inside and outside of the flexible liquid crystal cell during vacuumization and cracking of the liquid crystal cell caused by expansion is avoided. The crystal pouring device and method for the flexible liquid crystal cell solve the problem that cracking of the liquid crystal cell can be caused by expansion due to the fact that pressure difference is generated between the inner surface and outer surface of the flexible liquid crystal cell during vacuumization for crystal pouring, productivity is increased, and production cost is reduced.

Description

Technical field [0001] The invention relates to the technical field of flexible liquid crystal display, in particular to a crystal filling device of a flexible liquid crystal box and a crystal filling method thereof, and is suitable for the preparation process of a flexible liquid crystal device. Background technique [0002] At present, the crystal filling method of the liquid crystal cell prepared by using glass as a substrate has been very mature, and an excellent liquid crystal cell and production yield can be obtained. The existing method of filling the crystal of the flexible liquid crystal cell adopts the traditional filling method. On the one hand, the substrate of the flexible liquid crystal cell is made of flexible materials (PET, PC, etc.). During the vacuum process of filling the crystal, the inner and outer surfaces of the flexible liquid crystal cell A certain pressure difference is generated (the internal pressure of the liquid crystal cell is stronger than the ext...
