A light guide plate fixing structure and a backlight module using the same, comprising a first abutting wall formed at the side edge of the light guide plate, a second abutting wall formed on the backplane, and a constant-force spring arranged between the first abutting wall and the second abutting wall; the constant-force spring has a fixing end and a support end, the fixing end being fixed on the first abutting wall, the support end forming an elastic foot that abuts against the second abutting wall, with the light guide plate being fixed with the help of the elastic force produced by bounce of the constant-force spring after being pre-compressed: when the light guide plate is expanded, it can push the spring away and be released and expanded; when the light guide plate is contracted, rebound of the spring will make the spring move with the light guide plate.
A light guide plate fixing structure, for fixing a light guide plate on a backplane of a backlight module, wherein the light guide plate fixing structure comprises a first abutting wall formed at a side edge of the light guide plate, a second abutting wall formed on the backplane, and a constant-force spring arranged between the first abutting wall and the second abutting wall;
A backlight module, comprising a light guide plate, an LED array and a backplane, with the LED array arranged between the light guide plate and the backplane, wherein the backlight module further comprises a first abutting wall formed at the side edge of the light guide plate, a second abutting wall formed on the backplane, and a constant-force spring arranged between the first abutting wall and the second abutting wall;
