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

[0029] Fig. 3 is the improved liquid crystal tank with heating device, the front view of the whole liquid crystal tank is no longer a regular rectangle, but has a protrusion at the bottom, and a heater 9 is arranged inside it, after vacuumizing and defoaming, use to heat the liquid crystal. Figure 4 is the temperature distribution diagram inside and outside the liquid crystal after the heater is turned on. From near the heater to the surface, the temperature of the liquid crystal decreases gradually, and the temperature on the surface is kept low in equilibrium due to the cooling nitrogen to suppress volatilization. Figure 5 is a schematic diagram of the improved liquid crystal perfusion. The liquid crystal cell is a very thin layer, about 1.0MM, and the channels for blowing nitrogen are on both sides of the cell, as shown in Figure 6 and Figure 7.

[0030] Because the seal is deep into the surface of the liquid crystal, and the temperature distribution shown in Figure 4, the ...

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 the froth, 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 the liquid 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 pouring method and a special liquid crystal tank thereof. 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 with completely chaotic molecular arrangements, and also different from crystals with completely ordered molecular arrangements. On the one hand, liquid crystals have fluidity, on the other hand, liquids exhibit inherent spatial anisotropy of crystals, including dielectric anisotropy and optical anisotropy. In practical applications, the fluidity of liquid crystals, that is, the bulk viscosity, is extremely important, which directly affects the response time of liquid crystal displays, and will affect the difficulty, yield, and efficiency of the production process. [0003] Usually liquid crystal displays use nematic liquid...
