Light guide plate module

The invention relates to a light guide plate module, which comprises a framework provided with at least an accommodating space and an inner lateral surface, a light guide plate arranged in the accommodating space of the framework and at least provided with a first lateral surface, a second lateral surface, a third lateral surface, a fourth lateral surface and a light emergent surface perpendicular to each of the lateral surfaces; a light incident area on the first lateral surface; at least one light absorption structure at least arranged on one of the second lateral surface, the third lateral surface and the fourth lateral surface; and a light source arranged in the accommodating space of the framework and irradiating a light ray to the light incident area at a preset inclination angle, wherein the light ray passes through the light incident area and is at least irradiated to one of the second lateral surface, the third lateral surface and the fourth lateral surface; and when irradiated to the light absorption structure, the light ray is absorbed by the light absorption structure, thus the reflected light intensity of the lateral surface in which the light absorption structure is positioned is reduced, and the light emergent surface irradiates at an even brightness.
