Light guide plate, backlight source module and display device

Abstract

The invention relates to the technical field of backlight, in particular to a light guide plate, a backlight source module and a display device which are used for solving the problem of non-uniform light rays emitted by the conventional light guide plate due to the distribution design of a light emitting strip in the prior art. The light guide plate in the embodiment of the invention comprises a light guide main body part and a light emitting part positioned on one surface of the light guide main body part, wherein the light emitting part comprises a plurality of optical units arranged in the light guide direction; the lengths of the optical units in the light emitting part in the light guiding direction are unequal; each optical unit corresponding to a position where the light emitting strip is designed is shorter than an optical unit corresponding to a position where the light emitting strip is not designed, and one end surfaces, away from the light incident side of the light guide plate, of the optical units are flush with one another. Therefore, the light guide performances of the optical units at the light incident side of the light guide plate are ensured to be nearly consistent, the uniformity of scattering and reflection is improved, the light guide performances are improved, the light emitting uniformity of the light guide plate is ensured, and the quality of the light guide plate is improved.

Description

technical field [0001] The invention relates to the technical field of backlight sources, in particular to a light guide plate, a backlight source module and a display device. Background technique [0002] like figure 1 As shown, it is a schematic top view of the existing light guide plate structure. The light emitting portion 11 of the light guide plate includes a plurality of optical units 12 of equal length, that is, the two end faces (end face x1 and end face x2) of the optical unit 12 are flush. ; On the light-incident side of the light guide plate, as shown by the arrow, a plurality of light-emitting strips T (which need to be installed on the light guide plate and are not structural components of the light guide plate) are designed. figure 1 It can be seen that the light-emitting strips are evenly arranged according to the preset spacing. Therefore, the light-emitting part (as shown by the dotted line) at the position corresponding to the light-emitting strip T has a...
