[0141] In some embodiments of the present application, the packaging shell 1100 includes a first connecting corner piece 1120. The first connecting corner piece 1120 can be used to seal the fourth frame 740 and the end of the front shell 1110.

[0142] The first connecting corner piece 1120 is inserted into the fourth frame 740 and inserted into the front shell 1110 . The first connecting corner piece 1120 is detachably connected to the fourth frame 740 and detachably connected to the front shell 1110 .

[0143] In some embodiments of the present application, the packaging housing 1100 includes a second connecting corner piece 1140. The first connecting corner piece 1120 can be used to seal the second frame 720 and the end of the front housing 1110.

[0144] The second connecting corner piece 1140 is inserted into the second frame 720 and inserted into the front shell 1110 . The first connecting corner piece 1120 is detachably connected to the second frame 720 and detachably connected to the front shell 1110 .

[0145] See also Fig.21 As shown, in some embodiments of the present application, the packaging shell 1100 includes a rear shell 1130 .

[0146] The rear shell 1130 covers the first connecting corner piece 1120, the second connecting corner piece 1140, the first frame 710 and the front shell 1110, and the rear shell 1130 is detachably connected to at least one of the first connecting corner piece 1120, the second connecting corner piece 1140, the first frame 710 and the front shell 1110.

[0147] The rear case 1130 is located at a side close to the optical panel assembly. That is, the rear case 1130 is located at the rear side.

[0148] Exemplarily, the rear shell 1130 is detachably connected to the first connecting corner piece 1120 , the second connecting corner piece 1140 , the first frame 710 , and the front shell 1110 by means of screws.

[0149] See also Figure 7 and Figure 8 As shown, in some embodiments of the present application, the light panel assembly 800 includes: a base panel 810 and a light bar 100 .

[0150] The bottom plate 810 is slidably connected to the first guide rail and the third guide rail structure 741. It is understandable that the bottom plate 810 is used to replace the back plate 200 in the related art, and the bottom plate 810 does not need to be connected to the frame in the present application, thereby simplifying the structure and reducing costs.

[0151] In some embodiments, the bottom plate 810 may be in the form of a flat plate. The bottom plate 810 may be processed without a mold, and the cost is low.

[0152] The light bar 100 is disposed on a side of the bottom plate 810 facing the light film assembly 900 , and the light bar 100 is connected to the bottom plate 810 .

[0153] The light panel assembly 800 further includes a reflective sheet, which is disposed on a side of the bottom plate 810 facing the light film assembly 900 .

[0154] In some embodiments of the present application, the optical film assembly 900 includes a diffuser. The diffuser can evenly scatter the light source from the light bar 100 to form a uniform surface light source. This helps to eliminate bright spots and dark spots, making the brightness of the entire display device more uniform.

[0155] The diffusion sheet is slidably connected to the second guide rail and is slidably connected to the fourth guide rail structure 742 .

[0156] See also Fig. 9 and Fig.10 As shown, in some embodiments, the light film assembly 900 includes a film 300. The film 300 is used to improve the uniformity and brightness of the light source.

[0157] The film 300 is located on a side of the diffusion sheet facing the display panel 400 , and the film 300 and the diffusion sheet are stacked.

[0158] It can be understood that, compared with the diaphragm 300 , the diffuser has a greater hardness, is slidably connected to the second guide rail, and is slidably connected to the fourth guide rail structure 742 , is not easily worn, and is beneficial to increasing the service life of the optical film assembly 900 .
