A side 142 of the display panel 14 is disposed facing the side wall 124, with a gap defined therebetween.
The cover plate 16 is disposed on the display panel 14. A bottom surface 162 of the cover plate 16 and a top surface 144 of the display panel 14 can be joined in fully fitting manner. In detail, the bottom surface 162 and the top surface 144 can be joined by an optical clear adhesive (OCA). In the embodiment of the present disclosure, the cover plate 16 is a touch panel cover, that is, touch lines of a touch panel are integrated in the cover plate 16, and a touch operation can be realized by clicking on the cover plate 16. The cover plate 16 may be made of glass, sapphire, or polyvinyl chloride (PVC), etc. In some embodiments, the cover plate 16 includes a two-layer structure including a touch panel and a protective cover disposed on the touch panel. The touch panel is configured to perform a touch operation of the display panel assembly 10. The protective cover is configured to protect the touch panel from touching the touch panel to avoid direct touch operation of the touch panel.
The decorative ring 18 is disposed on the support 12, material of the decorative ring 18 is plastic, and the decorative ring 18 is joined to the support 12 by an in-mold injection molding process. The decorative ring 18 is disposed on a top end of the side wall 124 away from the bottom wall 122 and is joined to a side 164 of the cover plate 16. An inner wall 182 of the decorative ring 18 includes a first joining surface 1822, the side 164 of the cover plate 16 includes a second joining surface 1642 facing the first joining surface 1822, and the first joining surface 1822 and the second joining surface 1642 are inclined with respect to the side wall 124. In other words, the first joining surface 1822 and the second joining surface 1642 are inclined planes. The decorative ring 18 is joined to the side 164 of the cover plate 16 by gluing. In detail, the decorative ring 18 is joined to the side 164 of the cover plate 16 by dispensing a glue 19 to the side 164 of the cover plate 16. The glue 19 may be a gluewater, a solid glue, an ultraviolet curing glue, etc. An end of the first joining surface 1822 is closer to the display panel 14 relative to the side wall 124, that is, the first joining surface 1822 of the decorative ring 18 extends beyond the side wall 124 such that there is a gap between the display panel 14 and the side wall 124. An outer wall 184 of the decorative ring 18 has a curved arc shape. It is to be understood that the decorative ring 18 may be disposed around the side 164 of the cover plate 16.

When the display panel assembly 10 of the embodiment of the present disclosure is applied to the electronic device 100, entire width of the electronic device 100 is reduced.
In the display panel assembly 10 of the embodiment of the present disclosure, the first support component 120 and the second support component 121 having L shape are welded to form the support 12, and then the support 12 is subjected to an in-mold injection molding process, the decorative ring 18 is joined to the support 12, and then the second joining surface 1642 of the cover plate 16 and the first joining surface 1822 of the decorative ring 18 are joined by dispensing the glue. The display panel 14 and the cover plate 16 fully fitted to each other are disposed on the support 12, and a bottom surface 146 of the display panel 14 is joined to the top surface 1206 of the first support component 120 by gluing to form the display panel assembly 10. It is to be understood that the display panel 14 may be disposed on the support 12, and then the display panel 14 and the cover plate 16 are fully fitted.
The electronic device 100 according to the embodiment of the present disclosure can reduce entire width, save space and facilitate user operation by reducing the thickness of the side wall 124 of the support 12 of the display panel assembly 10 on one hand. It can also be achieved without increasing the entire width of the premise, increase size of the display to improve the panel ratio, to bring users a better experience of the operation on another hand.
Further, the decorative ring 18 is joined to the support 12 by the in-mold injection molding process. The in-mold injection molding process allows the decorative ring 18 to be better fitted with the support 12. The first joining surface 1822 and the second joining surface 1642 are inclined with respect to the side wall 124 to reduce horizontal widths and facilitate narrowing the width of the display panel assembly 10. The first joining surface 1822 and the second joining surface 1642 are joined by dispensing the glue, and the width required for the dispensing is small, and entire size of the electronic device 100 is made smaller.
Further, the first support component 120 and the second support component 121 having L shape are welded together to form the support 12, this molding method can reduce the thickness of the side wall 124 while ensuring that strength and rigidity of the support 12 meet the requirements. The material of the support 12 is metallic material, since mechanical properties of the metallic material are superior to those of ordinary plastics. The strength and rigidity of the support 12 can be increased, and the thickness of the support 12 can be reduced, thereby reducing entire volume of the electronic apparatus 100.
