[0026] like Figure 1 and Figure 2 As shown, this embodiment provides a light-emitting display frame, including a fixed frame 1, a light guide plate 2, and a back plate 3. The interior of the fixed frame 1 is hollow, which is convenient for installing the light guide plate 2 and the back plate 3. The display piece 4 to be displayed can be a photo, a poster, a light cloth or a canvas, etc., and is displayed through the display frame. The inner side of the fixed frame 1 is provided with an annular groove, and the light guide plate 2 and the back plate 3 are both clamped in the annular groove. The back plate 3 is white, and the back plate 3 and the light guide plate 2 are tightly arranged and clamped in the annular groove. The light guide plate 2 is equipped with a light-emitting body, which provides a light source for the display piece 4. The light-guiding effect of the light guide plate 2 facilitates the display of the display piece 4.

[0027] The surface of the fixed frame 1 is provided with an annular retaining groove, which is arranged longitudinally and transversely. The display piece 4 is positioned outside the light guide plate 2, parallel to the light guide plate 2, with the edges of the display piece 4 bent and retained in the annular retaining groove. The back panel 3, light guide plate 2, and display piece 4 are arranged in sequence. The illuminator provides the light source, and the light guide plate 2 acts to evenly distribute the light from the back of the display piece 4, enhancing the display effect of the display piece 4.

[0028] like Figure 2 As shown, the fixed frame 1 includes multiple end-to-end fixed profiles 5. The fixed profiles 5 are made of aluminum alloy. A first stopper and a second stopper are provided on the inner side of the fixed profile 5. A first slot 6 is provided between the first stopper and the second stopper. A second slot 7 is provided on the sidewall of the first stopper. The inner wall of the second slot 7 is provided with anti-slip teeth 8. The first slots 6 of the multiple fixed profiles 5 are interconnected to form the annular slot, and the second slots 7 of the multiple fixed profiles 5 are interconnected to form the annular stopper. The annular slot is provided on the inner wall of the fixed frame 1, and the annular stopper is provided on the outer wall of the fixed frame 1. The light guide plate 2 and the back panel 3 are both retained in the annular slot. The display piece 4 covers the outer side of the light guide plate 2. The edge of the display piece 4 is bent and retained in the annular stopper, thereby securing the display piece 4. The anti-slip teeth 8 provided on the inner wall of the second slot 7 effectively improve the retention of the display piece 4.
