Abstract
A backlight module is disclosed. The backlight module includes a light emitting component, a first light guide plate and a second light guide plate. The first light guide plate is disposed above the light emitting component and includes a first hole located correspondingly to the light emitting component. The second light guide plate is disposed between the light emitting component and the first light guide plate and includes a second hole. The second hole is located corresponding to the light emitting component and communicates with the first hole. The diameter of the second hole is greater than the diameter of the first hole.
Claims19
A backlight module, comprising:
- a light emitting component;
- a first light guide plate, disposed above the light emitting component, the first light guide plate comprising a first light receiving surface, a first hole and a first inner peripheral surface surrounding the first hole, wherein the first light receiving surface faces toward the light emitting component, and the first hole is located corresponding to the light emitting component;
- and
- a second light guide plate, disposed between the light emitting component and the first light guide plate, the second light guide plate comprising a second light receiving surface, a second hole and a second inner peripheral surface surrounding the second hole, wherein the second light receiving surface faces toward the light emitting component, and the second hole is located corresponding to the light emitting component and communicates with the first hole, where the diameter of the second hole is greater than the diameter of the first hole, such that a portion of the first light receiving surface protrudes above the second inner peripheral surface, thereby enabling light emitted from the light emitting component to enter the first light guide plate via the portion of the first light receiving surface, and to enter the second light guide plate via the second light receiving surface.
A backlight module, comprising:
- a light emitting component;
- a first light guide plate, disposed above the light emitting component, the first light guide plate including a first light receiving surface, a first hole and a first inner peripheral surface surrounding the first hole, wherein the first light receiving surface faces toward the light emitting component, and the first hole is located corresponding to the light emitting component;
- and
- a second light guide plate, disposed between the light emitting component and the first light guide plate, the second light guide plate including a second light receiving surface, a second hole and a second inner peripheral surface surrounding the second hole, wherein the second light receiving surface faces toward the light emitting component, and the second hole is located corresponding to the light emitting component and communicates with the first hole, where the spatial volume surrounded by the second inner peripheral surface is greater than the spatial volume surrounded by the first inner peripheral surface, such that a portion of the first light receiving surface protrudes above the second inner peripheral surface, thereby enabling light emitted from the light emitting component to enter the first light guide plate via the portion of the first light receiving surface, and to enter the second light guide plate via the second light receiving surface.
