Abstract

L'invention porte sur un joint de protection pour un module d'affichage d'un dispositif électronique portable et sur un procédé d'assemblage du dispositif. Le dispositif électronique comprend un cadre de logement, un corps principal comprenant un module d'affichage, et un joint flexible entre le cadre et le corps principal, le cadre comprenant une fenêtre d'affichage correspondant au module d'affichage. Une coupe est faite au niveau de parties de coin du joint de telle manière que des bords internes du joint flexible soient courbés après que le module d'affichage a été intégré dans la fenêtre d'affichage, et ensuite comprimés et ajustés entre la périphérie externe du module d'affichage et la périphérie interne de la fenêtre d'affichage. Les bords internes du joint flexible étant courbés, l'épaisseur du dispositif électronique peut être réduite, et la périphérie du module d'affichage peut être protégée. Le module d'affichage peut également être protégé contre une entrée de corps étrangers tels que de la poussière et de l'humidité.
