Abstract
(EN)
Provided is a display device. A support portion (40) is provided in a first relief groove (3011) of a rubber frame (301) for accommodating a printed circuit board (20), so that the support portion (40) supports the flexible printed circuit board (20) when the flexible printed circuit board (20) is subjected to a pulling force when assembled on the backlight module (30), thereby preventing a change in the box thickness of a liquid crystal display panel (10) due to the fact that the flexible printed circuit board (20) applies a force to the liquid crystal display panel (10) after being excessively pulled. Also provided are the rubber frame (301) and the backlight module (30).
(FR)
La présente invention concerne un dispositif d'affichage. Une partie de support (40) est disposée dans une première rainure de dégagement (3011) d'un cadre en caoutchouc (301) pour recevoir une carte de circuit imprimé (20), de telle sorte que la partie de support (40) soutient la carte de circuit imprimé souple (20) lorsque la carte de circuit imprimé souple (20) est soumise à une force de traction lorsqu'elle est assemblée sur le module de rétroéclairage (30), empêchant ainsi un changement dans l'épaisseur de boîte d'un panneau d'affichage à cristaux liquides (10), la carte de circuit imprimé souple (20) appliquant une force au panneau d'affichage à cristaux liquides (10) après avoir été excessivement tirée. L'invention concerne également le cadre en caoutchouc (301) et le module de rétroéclairage (30).

提供一种显示装置,通过在胶框(301)用于收容印刷电路板(20)的第一避位槽(3011)中设置支撑部(40),以使得柔性印刷电路板(20)在组装于背光模组(30)上而受到拉力时,支撑部(40)对柔性印刷电路板(20)起到支撑作用,防止柔性印刷电路板(20)受到过度拉扯而将力施加至液晶显示面板(10),导致液晶显示面板(10)的盒厚发生变化。还提供一种胶框(301)和背光模组(30)。
