The display panel 10 may be a liquid crystal panel (LCD panel), and accordingly, the light source for emitting light required by the display panel 10 may be an LED light source.

The middle frame 20 is a frame body exposed to the outside, and is used for carrying the display panel 10. The middle frame 20 includes a middle frame main body 230 and a bearing part 210, wherein the middle frame main body 230 has an appearance surface M1 exposed to the outside. The bearing part 210 is connected to an end of the middle frame main body 230 facing away from the appearance surface M1. The bearing portion 210 is disposed corresponding to the display panel 10 and is used for bearing the display panel 10. Further, the orthographic projection of the carrying part 210 on the display panel 10 falls within the range of the display area a1 and the non-display area a2, and the portion of the carrying part 210 corresponding to the display area a1 is transparent, in other words, the edge of the display area a1 of the display panel 10 is carried on the portion of the carrying part 210 which can transmit light.

The middle frame 20 can be formed by plastic double-shot molding. The middle frame main body 230 is opaque, and the material thereof may be, but not limited to, ABS + PC + GF, ABS + GF. The carrying part 210 may be formed by injection molding of transparent plastic, and the material of the carrying part 210 may be, but is not limited to, PMMA and PC. It should be noted that the carrying portion 210 may be completely transparent or partially transparent, and this application only exemplifies the complete transparency.

The adhesive member 30 is transparent to light and is adhered to the supporting portion 210 and the display panel 10. Specifically, the adhesive member 30 is an adhesive medium for adhering the carrier part 210 and the display panel 10 together. Optionally, the adhesive member 30 is an optical double-sided tape with an atomized light effect and high light transmittance, and in other embodiments, the adhesive member 30 may also be formed by curing light-permeable glue.

To sum up, the display device 1 provided in the embodiment of the present application includes a display panel 10, a middle frame 20 and an adhesive 30, wherein the display panel 10 is supported on the middle frame 20, a supporting portion 210 for supporting the display panel 10 is disposed on the middle frame 20, the supporting portion 210 is disposed corresponding to the display area a1 and the non-display area a2 of the display panel 10, and a portion of the supporting portion 210 corresponding to the display area a1 is transparent, that is, the supporting portion 210 can transmit light, and the supporting portion 210 and the display panel 10 are bonded together by the adhesive 30 that can transmit light, in other words, neither the supporting portion 210 nor the adhesive 30 disposed corresponding to the display area a1 can shield the display area a1, or light can transmit through the supporting portion 210 and the adhesive 30 and further irradiate the display area a1 of the display panel 10. Therefore, the display device 1 having the width of the non-display area a2 smaller than 3mm can avoid the problem of the formation of the dark shadow around the display area a1 in the related art by using this configuration. Of course, the above-described structural form can also be applied to the display device 1 in which the width of the non-display area a2 is greater than or equal to 3 mm.

Referring to fig. 1, the middle frame 20 further includes a connecting portion 220, and the connecting portion 220 is connected to a side of the middle frame main body 230 away from the appearance surface M1 in a bending manner. One end of the connecting portion 220 away from the appearance surface M1 is connected to the bearing portion 210. The connecting portion 220 and the middle frame body 230 may be integrally formed, and the forming method may be, but not limited to, injection molding. The connecting portion 220 is made of an opaque material, which may be, but is not limited to, ABS + PC + GF, ABS + GF.

Referring to fig. 1, the adhesive member 30 is adhered to the side of the bearing portion 210 and the side of the connecting portion 220 facing the display panel 10, so that the connection stability of the bearing portion 210 and the connecting portion 220 can be improved, the bearing portion 210 is prevented from being separated from the connecting portion 220, and the connection stability of the display panel 10 and the middle frame 20 is improved. Further, the display panel 10 is simultaneously supported by the supporting portion 210 and the connecting portion 220 through the adhesive 30, so that a part of the supporting force applied by the display panel 10 to the supporting portion 210 can be shared by the connecting portion 220, which is also beneficial to improving the connection stability of the display panel 10 and the middle frame 20.

Optionally, the width of the bearing portion 210 is a first width, the width of the connecting portion 220 is a second width, and the sum of the first width and the second width is greater than or equal to 3mm, that is, the distance from the side of the bearing portion 210 far from the appearance surface M1 to the middle frame main body 230 is greater than or equal to 3 mm. In general, if the display panel 10 and the middle frame 20 are bonded by using a double-sided adhesive tape, in order to ensure the adhesiveness of the double-sided adhesive tape, it is necessary to ensure that the bonding width of the double-sided adhesive tape is greater than or equal to 3 mm. In the present embodiment, the sum of the first width and the second width is set to be greater than or equal to 3mm, which satisfies the requirement of the bonding width of the double-sided adhesive tape, so that the bonding member 30 can use the double-sided adhesive tape with good light transmission performance to bond the display panel 10 and the middle frame 20. Of course, in other embodiments, the bonding may be performed by using glue, which is more costly than double-sided glue, and requires a certain curing time (usually greater than 10 minutes) during which the display panel 10 cannot be moved, resulting in low production efficiency and no reworking possibility. Therefore, compared with glue, the double-sided adhesive tape can save cost and improve production efficiency. In the present application, the type of the adhesive member 30 is not limited, and the adhesive member may be, but not limited to, a double-sided tape, glue, etc., and is determined according to actual requirements.
