Abstract
(EN)
Provided by the present application is a punching method for a liquid crystal display panel, comprising: providing a liquid crystal display panel having an array substrate and a color filter substrate arranged opposite to the array substrate; and punching the array substrate side of the liquid crystal display panel, while simultaneously punching the color filter substrate side at a location corresponding to the punching location of the array substrate side so as to form a concentric through hole that penetrates the array substrate and the color filter substrate. The described method may ensure high punching accuracy and product quality, simplifies the operation and improves production efficiency.

La présente invention concerne un procédé de poinçonnage destiné à un écran d'affichage à cristaux liquides, consistant : à fournir un écran d'affichage à cristaux liquides ayant un substrat de réseau et un substrat de filtre coloré disposé à l'opposé du substrat de réseau ; et à poinçonner le côté substrat de réseau de l'écran d'affichage à cristaux liquides, tout en poinçonnant simultanément le côté substrat de filtre coloré à un emplacement correspondant à l'emplacement de poinçonnage du côté substrat de réseau de façon à former un trou traversant concentrique qui pénètre dans le substrat de réseau et le substrat de filtre coloré. Le procédé décrit peut assurer une précision de poinçonnage et une qualité de produit élevées, simplifie l'opération et améliore l'efficacité de production.
