The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not used to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0031] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] See also Figure 1 The existing display frame generally includes four frames 1' of upper, lower, left and right, and four L-shaped connecting members 2'. The four frames 1' are connected end to end in sequence to form a rectangular structure. Two adjacent frames 1' are connected and fixed by a connecting member 2'. The screen 3' is fixed in the rectangular structure enclosed by the four frames 1'.

[0033] With the above-mentioned method, in the X' direction, two adjacent frames 1' are limited only by the connecting member 2', which may easily lead to the misalignment of the two adjacent frames 1' in the X' direction, resulting in appearance defects of the display frame. Moreover, when there is a misalignment between the two frames 1', it is easy to generate stress on the screen 3', causing the screen 3' to be easily deformed.

[0034] In the embodiment of the present application, a first protrusion 1112 is provided on one of the first frame 11 and the second frame 12, and a first recessed portion 1212 is provided on the other, and along the first direction X, the first recessed portion 1212 has a first side wall 1213 and a second side wall 1214 relative to each other, and at least a portion of the first protrusion 1112 is accommodated between the first side wall 1213 and the second side wall 1214, thereby limiting the displacement of the first frame 11 relative to the second frame 12 in the first direction X, reducing the misalignment between the first frame 11 and the second frame 12, and helping to reduce the stress generated by the frame assembly 100 on the screen 200, and helping to reduce the deformation of the screen 200 under the action of the stress.
