Abstract

La présente invention concerne un dispositif électronique (100) comprenant : un support de tôle (2) en forme de boîte ; et un module à cristaux liquides (1) logé dans le support (2) et dont une partie de face arrière est opposée à une partie de surface inférieure (21) du support (2). De premières parties de paroi latérale (22a, 22b) du support (2) présentent des fentes dont les directions longitudinales sont perpendiculaires à la direction d'épaisseur de plaque du module à cristaux liquides (1) et des parties de ressort à lames (27a, 27b) en tôle sont formées au niveau de parties adjacentes le long des fentes. Les parties de ressort à lames (27a, 27b) ont des premières parties convexes (28a, 28b) qui font saillie à l'intérieur du support (2) et les premières parties convexes (28a, 28b) viennent en butée contre des parties de face latérale du module à cristaux liquides (1).
