Abstract
A backlight module includes a tray, a light guide plate, a lighting device, and an optical film set. The tray includes a bottom plate and a side wall connecting an edge of the bottom plate. The side wall includes a plurality of wall portions connected to one another. Some of the wall portions are perpendicular to the bottom plate, and the others are parallel to the bottom plate. The light guide plate is disposed on the bottom plate. The lighting device is disposed at a light incident side of the light guide plate. The optical film set disposed on the light guide plate leans against the side wall.
Claims32
A backlight module comprising:
- a tray comprising a bottom plate and a side wall connecting an edge of the bottom plate, the side wall comprising:
- a first wall portion substantially perpendicular to the bottom plate;
- a second wall portion substantially parallel to the bottom plate, the second wall portion extending out of the tray;
- a third wall portion substantially perpendicular to the bottom plate, the second wall portion being connected between the first wall portion and the third wall portion;
- a fourth wall portion substantially parallel to the bottom plate, the fourth wall portion extending out of the tray;
- a fifth wall portion substantially perpendicular to the bottom plate, the fourth wall portion being connected between the third wall portion and the fifth wall portion;
- a light guide plate disposed on the bottom plate of the tray;
- a back frame surrounding the tray, the back frame and the tray leaning against each other, a bottom surface of the tray and a bottom surface of the back frame being substantially coplanar;
- a lighting device disposed at a light incident side of the light guide plate;
- and
- an optical film set disposed on the light guide plate, the second wall portion leaning against the optical film set.
A liquid crystal display module comprising:
- a tray comprising a bottom plate and a side wall connecting an edge of the bottom plate, the side wall comprising:
- a first wall portion substantially perpendicular to the bottom plate;
- a second wall portion substantially parallel to the bottom plate, the second wall portion extending out of the tray;
- a third wall portion substantially perpendicular to the bottom plate, the second wall portion being connected between the first wall portion and the third wall portion;
- a fourth wall portion substantially parallel to the bottom plate, the fourth wall portion extending out of the tray;
- a fifth wall portion substantially perpendicular to the bottom plate, the fourth wall portion being connected between the third wall portion and the fifth wall portion;
- a light guide plate disposed on the bottom plate of the tray;
- a lighting device disposed at a light incident side of the light guide plate;
- an optical film set disposed on the light guide plate, the second wall portion leaning against the optical film set;
- a liquid crystal display panel disposed over the optical film set, the fourth wall portion leaning against the liquid crystal display panel;
- and
- a flexible encapsulating material covering a portion of the liquid crystal display panel and a portion of the bottom plate of the tray, so as to fix the liquid crystal display panel and the tray together.
