METHOD OF FILLING OF DISPLAY PACK WITH LIQUID-CRYSTALLINE SUBSTANCE Russian patent published in 1997 - IPC

FIELD: fabrication of products of optoelectronics, applicable in video devices, in which liquid crystal serves as optical medium and member, in particular, at filling of the display pack with liquid crystal. SUBSTANCE: method consists in successive arrangement of liquid crystal and display pack in a pressurized chamber, degassing of the pack and liquid crystal in the process of chamber vacuum treatment, submersion of the pack with the filling hole in liquid-crystalline substance, filling of the pack with liquid crystal by depressurization of the chamber, pressurization of the pack filling hole; degassing of liquid - crystalline substance and filling of the pack are accomplished at a temperature exceeding the temperature of isotropic state of liquid-crystalline substance in vacuum, and vacuum treatment of the chamber and display pack is conducted at a temperature not exceeding the solidification temperature of liquid-crystalline substance. EFFECT: facilitated procedure. 1 tbl
