[0066] The following embodiments illustrate the structure of the adapter assembly 40 of the present utility model embodiment:

[0067] In an optional embodiment, if Figure 2 As shown, the adapter assembly 40 includes:

[0068] The annular member 41 surrounding the cover plate 10 at the second end portion 40B, and the adhesive material 50 is used to fix the annular member 41 and the cover plate 10;

[0072] In the embodiment of the utility model, the adapter assembly 40 is designed to be four parts. The connecting member 42 serves as an indirect fixing structure for the backlight module 30 and the cover plate 10 to realize a frameless structure. The annular member 41 and the second locking member 44 are used to fix the connecting member 42 and the cover plate 10. The first locking member 43 is used to fix the connecting member 42 and the backlight module 30, so that the cover plate 10 is fixed on the side close to the backlight module 30 and the non-light-emitting side of the backlight module 30. That is to say, in the embodiment of the utility model, the cover plate 10 is fixedly designed as a horizontal surface rather than the side wall of the cover plate 10. Through this arrangement, there is no need to use a frame to cover the cover plate 10 and the side wall of the backlight module 30 to achieve fixation, thereby realizing a design of a frameless structure.

[0073] In an optional embodiment, if Figure 3 and Figure 4 As shown, the annular member 41 includes a first protection portion 411 and a second protection portion 412 located in a direction where the first protection portion 411 is away from the cover plate 10.

[0074] The first protection portion 411 includes a first protruding structure 4111 and an adhesive fixing portion.
