US 12,601,945 B2 · Frame structure, backlight module and display device

Abstract

A frame structure includes an inner frame and a plurality of outer frames combined with the inner frame. The inner frame has at least one first joint member disposed on its outer surface, and the first joint member extends at least along a first direction. The outer frames are detachably combined with the inner frame along the first direction, so that the inner frame is surrounded by the outer frames. Each of the outer frames has at least one second joint member disposed on its inner surface. Each of the outer frames is combined with the inner frame through the cooperation between the second joint member and the first joint member of the inner frame in the first direction. Assembling the inner frame directly with the outer frames can reduce the number of assembly parts and improve the convenience of assembly and rework. The invention also provides a backlight module and a display device including the frame structure.

Dependent claims

A frame structure, comprising:

an inner frame, including at least one first joint member disposed on its outer surface, wherein the first joint member extends along at least a first direction on the outer surface;
and
a plurality of outer frames, which surround the inner frame and are detachably coupled to the inner frame along the first direction, each of the outer frames has at least one second joint member disposed on its inner surface, and the at least one second joint member of each said outer frame cooperates with the at least one first joint member of the inner frame in the first direction to combine the outer frame with the inner frame;
wherein the at least one second joint member can cooperate and slide within the at least one first joint member of the inner frame in the first direction;
wherein the inner frame further includes a plurality of reflective portions arranged in a matrix, and a surrounding portion surrounding the reflective portion, and the at least one first joint member is disposed on the outer surface of the surrounding portion.

A backlight module, comprising:

a light source, including a board and a plurality of light-emitting elements arranged in a matrix on the board;
a reflective unit, including a plurality of reflective portions arranged in a matrix, a surrounding portion surrounding the reflective portions, and at least one first joint member provided on the surrounding portion, the at least one first joint member extends along at least a first direction on the outer surface of the surrounding portion, wherein, each of the reflective portions has an opening, and the reflective unit is arranged on the board so that the light-emitting elements pass through the corresponding openings and extend into the corresponding reflecting portions;
and
a plurality of outer frames, which surround the reflective unit and are detachably coupled to the reflective unit along the first direction, each of the outer frames has at least one second joint member disposed on its inner surface, and the at least one second joint member of each said outer frame cooperates with the at least one first joint member of the reflective unit in the first direction to combine the outer frame with the reflective unit.
