Abstract

Un boîtier avant de terminal comprend un corps de boîtier avant. Une rainure assemblée avec une pièce de rétroéclairage d'un module ACL et quatre cadres sur la périphérie de la rainure sont formés sur le corps de boîtier avant. Une structure de connexion d'un élément d'affichage fixe est prévue sur une paroi interne d'au moins deux cadres opposés parmi les quatre cadres. Une structure de boîtier avant d'un terminal comprend le corps de boîtier avant, un écran tactile, une partie d'affichage du module ACL, et la partie de rétroéclairage du module ACL. Le boîtier avant est conçu avec des paliers/boucles pour le montage de matériaux en film de la partie de rétro-éclairage du module ACL, ce qui est pratique pour l'assemblage des matériaux en film, et la partie d'affichage du module ACL est directement en contact avec un cadre en plastique supérieur du boîtier avant, ce qui réduit efficacement la taille des cadres du module et facilite sensiblement la conception de cadres étroits et la mise en forme de l'ensemble.
