Abstract
(EN)
Provided are a method and a system for preparing a curved glass sheet, a glass cover plate, and an electronic device. Said method comprises: placing a planar glass preform plate in a molding die and fixing same, a sealed first cavity being formed between a first mold and the glass preform plate, and a sealed second cavity being formed between a second mold and the glass preform plate; introducing a molding medium into the first cavity and the second cavity, and maintaining the pressure in the first cavity to match the pressure in the second cavity, and heating the glass preform plate; and forming a pressure difference between the first cavity and the second cavity, so that the glass preform plate is adhered to the second mold, so as to form a curved glass sheet.
(FR)
La présente invention concerne un procédé et un système de préparation d'une feuille de verre incurvée, une plaque de couverture en verre et un dispositif électronique. Ledit procédé comprend : le placement d'une plaque de préforme de verre plane dans une matrice de moulage et la fixation de ladite plaque, une première cavité scellée étant formée entre un premier moule et la plaque de préforme de verre et une seconde cavité scellée étant formée entre un second moule et la plaque de préforme de verre ; l'introduction d'un milieu de moulage dans la première cavité et dans la seconde cavité en maintenant une pression dans la première cavité identique à la pression dans la seconde cavité et en chauffant la plaque de préforme en verre ; et la formation d'une différence de pression entre la première cavité et la seconde cavité, de telle sorte que la plaque de préforme de verre adhère au second moule de façon à former une feuille de verre incurvée.
