[0049] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0050] Combination Figure 1 and Figure 2 As shown, an embodiment of the present application provides an electronic device, and the electronic device includes a middle frame 100, a backlight assembly 200 and a screen assembly 300. It should be noted that the electronic device in the embodiment of the present application can be a mobile phone, a computer, a tablet, a smart wearable product, an e-book, a vehicle, etc. The backlight assembly 200 is located between the screen assembly 300 and the middle frame 100, and the backlight assembly 200 includes an optical module 210 for realizing an optical function. Thereby, the light emitted by the light source in the electronic device can be transmitted to the screen assembly 300 through the optical module 210, so as to realize the display function of the electronic device. It should be noted that the light source for emitting light in the electronic device can be set on one side of the optical module 210.

[0051] The middle frame 100 includes a first surface 110 facing the backlight assembly 200, and the first surface 110 carries the optical module 210. It should be noted that since the optical module 210 is directly mounted on the middle frame 100, there is no need to additionally set a back plate between the optical module 210 and the middle frame 100, and the middle frame 100 additionally assumes the function of the back plate, thereby reducing the overall thickness of the backlight assembly 200, and also reducing the number of stacked components in the electronic device, thereby reducing the thickness of the electronic device, making the electronic device thinner and lighter.

[0052] The following is combined with Figures 1 to 4 The various components and functions of the electronic device provided in the embodiments of the present application are described in more detail.

[0053] Combination Figure 1 and Figure 2 As shown, in some embodiments, the electronic device further includes a first adhesive 400, and the first adhesive 400 adheres to the first surface 110 and the side of the optical module 210. It can be understood that the optical module 210 can be fixed to the middle frame 100 by the first adhesive 400 to prevent the position of the optical module 210 from shifting during shaking or vibration of the electronic device and affecting light propagation.

[0054] Combination Figure 1 and Figure 2 As shown, in some embodiments, the optical module 210 includes a reflective sheet 211 and a light guide plate 212 stacked in sequence in the direction from the first surface 110 to the screen assembly 300, and the orthographic projection of the light guide plate 212 on the first surface 110 is located within the orthographic projection of the reflective sheet 211 on the first surface 110. The first adhesive 400 adheres to the side of the light guide plate 212, the surface of the reflective sheet 211 facing the screen assembly 300, and the first surface 110 in sequence to connect the light guide plate 212 and the reflective sheet 211 and fix them on the first surface 110. It should be noted that the position where the reflective sheet 211 is adhered to the first adhesive 400 is the partial surface of the reflective sheet 211 that does not overlap with the light guide plate 212. The light guide plate 212, the reflective sheet 211, and the middle frame 100 can be fixed together more stably by using the first adhesive 400. The first adhesive 400 can be adhered to any one or more sides of the light guide plate 212 as required.

[0055] Combination Figure 1 and Figure 4 As shown, in some embodiments, the optical module 210 further includes a diffusion sheet 213 and a prism sheet 214 stacked between the light guide plate 212 and the screen assembly 300. It should be noted that the number of diffusion sheets 213, the number of prism sheets 214, and the stacking order of the diffusion sheets 213 and the prism sheets 214 between the light guide plate 212 and the screen assembly 300 can be adjusted as required.

[0056] At least one first clamping structure 215 is provided on the circumference of the diffusion sheet 213, and at least one second clamping structure 216 is provided on the circumference of the prism sheet 214. The middle frame 100 includes a side wall 120, which is connected to the circumference of the first surface 110 and extends toward the screen assembly 300. The side wall 120 is provided with a third clamping structure 121 clamped to the first clamping structure 215 and a fourth clamping structure 122 clamped to the second clamping structure 216. It should be noted that the efficiency of assembling the middle frame 100, the prism sheet 214 and the diffusion sheet 213 can be improved through the cooperation between the various clamping structures, and it can also ensure that the diffusion sheet 213 and the prism sheet 214 will not easily shake, thereby ensuring the stability of light propagation.

[0057] Combination Figure 4 As shown, in some embodiments, either the first clamping structure 215 or the third clamping structure 121 is a protrusion, and the other is a groove. Either the second clamping structure 216 or the fourth clamping structure 122 is a protrusion, and the other is a groove. This makes it easier to assemble the diffusion sheet 213 and the prism sheet 214 on the middle frame 100. It should be noted that the protrusions correspond to the grooves one by one, and the number of protrusions and the number of grooves can be adjusted according to needs.

[0059] Combination Figure 1 and Figure 4 As shown, in some embodiments, the first protruding structure 130 extends along the circumference of the first surface 110. The orthographic projection of the portion of the second surface 310 connected to the third surface 131 on the first surface 110 is located within the orthographic projection of the third surface 131 on the first surface 110. This arrangement ensures that the first protruding structure 130 overlaps the edge of the screen assembly 300, ensuring that the first protruding structure 130 can effectively and stably support the screen assembly 300.

[0060] Combination Figure 1 and Figure 2As shown, in some embodiments, the backlight assembly 200 further includes a shading member 220, which is adhesive. The shading member 220 is located between the first protruding structure 130 and the screen assembly 300, and the two sides of the shading member 220 are respectively bonded to the third surface 131 and the second surface 310. Thus, the screen assembly 300 can be more stably fixed on the first protruding structure 130 through the shading member 220, so as to prevent the screen assembly 300 from shaking.

[0061] Combination Figure 1 and Figure 2 As shown, in some embodiments, the shading member 220 is opaque, and the shading member 220 extends along the circumference of the screen assembly 300. The shading member 220 includes a fourth surface 221 facing the screen assembly 300 and a fifth surface 222 facing the first protruding structure 130, and the fourth surface 221 is bonded to the second surface 310.

It should be noted that the shading member 220 is arranged in the above manner, which can prevent the light emitted by the optical module 210 from leaking from the gap between the first protruding structure 130 and the second surface 310 of the screen assembly 300, thereby improving the light utilization rate and the lighting effect. It should be noted that the shading member 220 can be a sticky shading tape.

[0062] Combination Figure 1 and Figure 2 As shown, in some embodiments, the electronic device further includes a cover plate 500, which is located on the side of the screen assembly 300 away from the optical module 210. It should be noted that the cover plate 500 in the embodiment of the present application can be a glass cover plate, which can protect the screen assembly 300, prevent the screen assembly 300 from being damaged, and ensure the normal use of the function of the screen assembly 300.

[0063] Combination Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the middle frame 100 further includes a second protruding structure 140, the second protruding structure 140 protrudes from the first surface 110 toward the cover plate 500, and the second protruding structure 140 extends along the circumference of the first surface 110, and is located on the outer side of the first protruding structure 130 away from the backlight assembly 200. The surface of the cover plate 500 facing the second protruding structure 140 is connected to the second protruding structure 140. Thus, the first protruding structure 130 can support the cover plate 500. It should be noted that the second protruding structure 140 can be located between the first protruding structure 130 and the side wall 120. The first protruding structure 130, the second protruding structure 140, the side wall 120, and the wall surface where the first surface 110 is located can be an integrally formed structure.
