[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-Figure 3 As shown, an embodiment of the present application provides a special-shaped frameless light-emitting panel, including a frameless light-emitting panel 100, wherein the frameless light-emitting panel 100 includes a diffuser 1, a light guide plate 2, a light bar 3, a silver-black double-sided adhesive tape 4, a reflective film 5 and a light-shielding tape 6. A groove 21 for accommodating the light bar 3 is provided on one end face of the light guide plate 2, and the groove 21 is adapted to the edge shape of the light guide plate 2. The light bar 3 is attached to the inner side of the groove 21. The diffuser 1 is in contact with one end of the light guide plate 2 away from the groove 21. The silver-black double-sided adhesive tape 4 is attached to the open end of the groove 21 along the outer edge of the light guide plate 2. The reflective film 5 is in contact with the silver-black double-sided adhesive tape 4 and the light guide plate 2 respectively. The light-shielding tape 6 is wrapped and attached to the outer surfaces of the diffuser 1, the light guide plate 2, the silver-black double-sided adhesive tape 4 and the reflective film 5.

[0025] Specifically, a groove 21 for accommodating the light bar 3 is provided on one end face of the light guide plate 2, and the shape of the groove 21 matches the shape of the edge of the light guide plate 2. The light bar 3 is attached to the inner side of the groove 21, and then the silver-black double-sided adhesive tape 4 is attached to the open end of the groove 21 along the outer edge of the light guide plate 2, and then the reflective film 5 is attached to the side of the light guide plate 2 that is attached to the silver-black double-sided adhesive tape 4, and then the diffuser plate 1 is placed on the side of the light guide plate 2 that is away from the silver-black double-sided adhesive tape 4, and finally the light-shielding tape 6 is attached to the outer side of the diffuser plate 1, the light guide plate 2, the silver-black double-sided adhesive tape 4 and the reflective film 5, so as to fix the diffuser plate 1, the light guide plate 2, the silver-black double-sided adhesive tape 4 and the reflective film 5. Among them, the thickness of the diffuser plate 1 is 5 mm, the thickness of the light guide plate 2, the light bar 3, the silver-black double-sided adhesive tape 4, the reflective film 5 and the light-shielding tape 6 combined together is 6 mm, and the overall thickness of the frameless light-emitting panel 100 is 11 mm. The overall thickness of the existing frameless light-emitting panel 100 is 18 mm, 15 mm and 21 mm respectively.

[0026] In the above structure, by providing a groove 21 on the light guide plate 2 that matches the shape of the edge of the light guide plate 2, the light bar 3 can be attached to the groove 21, and no additional fixing components are needed to connect the light bar 3 to the light guide plate 2, so that the volume and thickness of the frameless light-emitting board 100 are reduced. In addition, by using a silver-black double-sided adhesive 4 attached to the open end of the groove 21, the light absorption effect can be achieved, which can reduce the light on the light-emitting surface and achieve a better borderless effect. The special-shaped frameless light-emitting board is not only simple in structure and thin in thickness, but also has a good borderless effect.

[0027] like Figure 4 and Figure 5 As shown, in one of the embodiments, the borderless light-emitting panel 100 of the special-shaped borderless light-emitting panel is a special-shaped structure.

[0028] Specifically, the special-shaped structure can be a wave shape, a square shape, a circle shape, a triangle shape, an arrow shape, etc. This setting can facilitate the use of different structural shapes according to user needs.

[0029] like Figure 4 and Figure 5 As shown, in one embodiment, the groove 21 of the special-shaped frameless light-emitting panel is spaced 1-2 mm from the edge of the light guide plate 2, the groove width of the groove 21 is 2-3 mm, and the sealing end of the groove 21 is spaced 1-2 mm from the other end surface of the light guide plate 2.

[0030] Specifically, the groove 21 is spaced 1mm, 1.5mm and 2mm from the edge of the light guide plate 2, preferably 1mm. The groove width of the groove 21 is 2mm, 2.5mm and 3mm, preferably 2mm. The sealed end of the groove 21 is spaced 1mm, 1.5mm and 2mm from the other end face of the light guide plate 2, preferably 1mm. The groove 21 not only matches the edge of the light guide plate, but also has a good borderless effect.

[0031] like Figure 2 As shown, in one embodiment, one end of the light-shielding tape 6 of the special-shaped frameless light-emitting panel does not completely overlap with the outer side surface of the diffusion plate 1 , and the other end of the light-shielding tape 6 overlaps with the outer side surface of the reflective film 5 .

[0032] Specifically, one end of the light shielding tape 6 is spaced 0.5-1 mm from the upper end surface of the diffuser plate 1, so that the light shielding tape 6 does not completely overlap with the outer side surface of the diffuser plate 1, which can prevent the light shielding tape 6 from falling off during use. The other end of the light shielding tape 6 overlaps with the reflective film 5, so that the reflective film 5 is firmly attached to the light guide plate 2 and the silver-black double-sided tape 4.

[0033] like Figure 2 As shown, in one of the embodiments, the diffusion plate 1, the light guide plate 2 and the reflective film 5 of the special-shaped frameless light-emitting panel are of the same shape and correspond one to one.

[0034] Specifically, the diffuser plate 1 is in contact with one end surface of the light guide plate 2, the reflective film 5 is in contact with the other end surface of the light guide plate 2, and the diffuser plate 1, the light guide plate 2 and the reflective film 5 have the same shape and correspond to each other. The reflective film 5 can reflect the light on the light guide plate 2 to the light-emitting surface, thereby increasing the brightness of the light-emitting surface and reducing light loss.

[0035] like Figure 2 As shown, in one of the embodiments, the outer side of the silver-black double-sided adhesive tape 4 of the special-shaped frameless light-emitting panel is flush with the side surface of the light guide plate 2 .

[0036] This setting can absorb light from the light strip 3, reduce the brightness of the light-emitting surface, and achieve a borderless effect.

[0037] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
