Problems solved by technology

The effective way to prevent and improve this kind of defect is to control the nitrogen gas intake speed to ensure that the liquid crystal enters the empty box very slowly, so as to reduce the damage of the liquid crystal to the alignment layer, but this will seriously restrict the production speed and inefficiency

Embodiment Construction

[0031] image 3 It is an improved liquid crystal cell with a heating device. The front view of the entire liquid crystal cell is no longer a regular rectangle, but has a bump at the bottom. A heater 9 is installed inside, which is used for heating after vacuuming and defoaming. liquid crystal. Figure 4 After the heater is turned on, the temperature distribution of the inside and outside of the liquid crystal is shown. From approaching the heater to the surface, the temperature of the liquid crystal decreases. Due to the effect of the cooling nitrogen on the surface, the temperature remains low in equilibrium to suppress volatilization. Figure 5 It is a schematic diagram of the improved liquid crystal perfusion. The liquid crystal cell is a very thin layer, about 1.0mm. The channels for blowing nitrogen are on both sides of the cell. Image 6 , Figure 7 Shown.

[0032] Since the sealing is deep into the liquid crystal surface, Figure 4 According to the temperature distribution ...

Abstract

This invention relates to a kind of new liquid perfusion method and its specific liquid slot, the method is that drip the prepared liquid in to the improved liquid slot, pumps vacuum to get rid of thefroth, when the degree of the vacuum reaches the request, rises the liquid slot, and it stops when it touch the glass seal of the empty box, open the heater in the liquid slot to heat the liquid, open the air intake in side of the liquid slot when it reach a certain degree, to make the cold low temperature blow to the surface of the liquid in short distance, to restrain the volatilization of theliquid when the temperature is high. The liquid in high temperature in the seal of the empty box pours in the liquid box in very low viscosity, so it can avoid the breakage of the directional layer round the seal, improves the pour effect of the liquid efficiently.

Description

Technical field [0001] The invention relates to a new liquid crystal perfusion method and a special liquid crystal tank. Background technique [0002] Liquid crystal is a partially ordered substance composed of rod-shaped molecules, disc-shaped molecules and other molecules that do not have spherical symmetry. It is different from isotropic liquids in which the molecular arrangement is completely chaotic, and it is also different from crystals in which the molecular arrangement is completely ordered. On the one hand, the liquid crystal has the fluidity of a fluid. On the other hand, the liquid shows the inherent spatial anisotropy of the crystal, including dielectric anisotropy and optical anisotropy. In practical applications, the fluidity of the liquid crystal, that is, the volume viscosity is extremely important, which directly affects the response time of the liquid crystal display, and also affects the difficulty of the production process, yield, and efficiency.
