a display screen, an edge of an inside surface of the display screen being fixed to an outside surface of the joining flange; and
an optical film set mounted in the mounting space.

2. The display module as claimed in claim 1 , wherein,
the edge of the inside surface of the display screen is bonded to the outside surface of the joining flange through double-sided glue; or
the outside surface of the joining flange is stamped and formed with a glue storage groove, the edge of the inside surface of the display screen is bonded to the outside surface of the joining flange through adhesive glue, and the glue storage groove is filled with the adhesive glue; and a width of a cross section of the glue storage groove is gradually increased in a depth direction of the glue storage groove.

3. The display module as claimed in claim 1 , wherein,
an end surface of the free end of the side wall is higher than or flushed with the outside surface of the display screen.

4. The display module as claimed in claim 1 , wherein
there are a plurality of side walls, joining flanges of two adjacent ones of the side walls are provided in a mutual butt joint way and welded and fixed at a butt joint.

5. The display module as claimed in claim 1 , wherein,
the optical film set comprises a first film disposed adjacent to an inner side of the display screen, and an edge of the first film is provided with a side protrusion;
the joining flange is provided with an avoiding notch, the avoiding notch is provided with a mounting member, the mounting member is defined with a mounting sink on an outside surface of the mounting member, and the side protrusion is clamped in the mounting sink.

6. The display module as claimed in claim 5 , wherein
a depth of the mounting sink is not less than a thickness of the side protrusion.

7. The display module as claimed in claim 5 , wherein,
the mounting member is in an elongated strip shape, and both ends of the mounting member in a longitudinal direction are riveted and fixed to two opposite side edges of the avoiding notch, or the mounting member is clamped or glued to the avoiding notch;
the two opposite side edges of the avoiding notch are set to be sunk; and
the mounting member is a sheet metal piece, an injection molded piece or a casting piece.

8. The display module as claimed in claim 5 , wherein
the side protrusion is defined with a hanging hole, the mounting sink is provided with a hooking protrusion, an area of the mounting sink is larger than an area of the side protrusion, and the hanging hole is engaged with the hooking protrusion; or
the side protrusion is bonded to the mounting sink; and
the hanging hole is larger than the hooking protrusion.

9. The display module as claimed in claim 1 , wherein
the optical film set comprises a light guide plate provided at an inner side of the display screen, a positioning member is provided at an inner side of the side wall, and a side edge of the light guide plate is abutted against the positioning member.
