Abstract
The present invention relates to a backlight module suitable for transportation, which comprises a backlight unit, the backlight unit comprises a backplate, and a light source, as well as an optical film, a light guide plate and a reflection plate arranged in sequence on the backplate from up to down; the backlight module further comprises a fixing belt used for fixing the optical film, the fixing belt being tightly tied outside the backlight unit along at least one of the length and width directions of the backlight unit. This backlight module uses the fixing belt to fix the optical film instead of using the rubber frame to press against the optical film, thus the cost of the rubber frame assembly is saved, the optical film can be prevented from translocating due to vibration, and the winding strength can be ensured to be moderate.
