Document Type and Number:
WIPO Patent Application WO/2013/056478
Kind Code:
A1
Abstract:
A backlight module (200) and a ventilation element (100) are provided. A multiple of ventilation elements (100) are arranged on a back plate (210) of the backlight module (200). The ventilation element (100) contains a tube (10), a ventilation membrane (20), a membrane gasket (30) and a fixed ring (40).The tube (10) is hollow annular shaped, within which the ventilation membrane (20) is carried. The internal and external air of the backlight module (200) are ventilated by means of the ventilation elements (100) and thus the temperature of the internal air is reduced effectively, so as to decrease the thermal expansion of the light guiding plate (220) within the backlight module (200), as a result, the optical problem generated by the light guiding plate (220) is avoided.
