Problems solved by technology

[0002] Due to the structural characteristics of PMVA itself, small box thickness, and poor wettability of PI materials, the filling speed is slow. The properties of PMVA’s PI material are different from ordinary PI materials. VAPI has strong polarity, poor surface wettability, and high surface tension. It is precisely because of this characteristic that the capillary phenomenon becomes weaker during liquid filling, and the resistance of the liquid crystal is large when it rises. In addition to the structural characteristics of PMVA itself, the thickness of the cell is small, the rising speed of the liquid crystal slows down, and the production efficiency of liquid filling is low, which is not conducive to mass production.

Embodiment Construction

[0017] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0018] Such as figure 1 As shown, a method for improving the efficiency of PMVA filling includes the following steps: Step 1: Put the liquid crystal box with an opening into the filling machine, and vacuumize the inside of the filling machine; Step 2: Lower the liquid crystal box to the liquid crystal During the process, make the liquid crystal liquid surface submerge the filling port of the liquid crystal box; step 3: quickly fill nitrogen into the filling machine; step 3: quickly open the furnace door of the liquid filling machine, so that the inside and outside of the liquid crystal box reach the maximum pressure difference; Step 4: Transfer the liquid crystal glass obtained in the filling machine from the fillin...

Abstract

The invention relates to a method for improving the filling efficiency of PMVA. The method includes the first step of placing a liquid crystal box with an opening into a filling machine and vacuumingthe filling machine; the second step of lowering the liquid crystal box into liquid crystal, and causing the liquid crystal liquid level to be higher than the filling opening of the liquid crystal box; the third step of quickly inflating the filling machine with nitrogen; the third step of quickly opening a furnace door of the filling machine, so that the maximum pressure difference is reached inside and outside the liquid crystal box; the fourth step of transferring liquid crystal glass obtained in the filling machine to a clean chamber, and continuing the filling. According to the technicalscheme, the peculiarities of the structure and material of PMVA filling can be overcome, the method capable of simply and quickly improving filling efficiency can be provided, and the filling efficiency of the large-size PMVA can be increased by 50% or above.
