Abstract
A holder is disposed at a side of a back light module adjacent to a light incident side of a light guide plate (LGP). A light source module is fixed on a wall of the holder that faces the light incident side. A holder engager on a side wall of the LGP engages with an LGP retainer of the holder. When the LGP expands or contracts due to changes of temperature, the holder and the light source module move with the side of the LGP, thereby a gap between the light source module and the light incident side is maintained and the luminance of the backlight module is stabilized.
Claims19
A backlight module comprising:
- a back plate comprising a fixing component;
- a light guide plate comprising:
- a light incident side;
- and
- a lateral side connected to the light incident side, the lateral side comprising:
- a first fastening component for engaging with the fixing component of the back plate so as to fix the light guide plate on the back plate;
- and
- a second fastening component connected to the first fastening component;
- a holder disposed between the back plate and the light guide plate comprising:
- a retainer for engaging with the second fastening component of the light guide plate so as to limit displacement of the light guide plate;
- and
- a fixing component connected to the retainer;
- and
- a light source module fixed on the fixing component of the holder, and a gap being formed between the light source module and the light incident side of the light guide plate.
