When installed, the light guide plate 70 can be connected to the shell 10 by screws, buckles, double-sided tape or other fixing methods. In order to realize the light-emitting display function, a group of LED lights or other types of light sources are usually arranged inside or on the edge of the light guide plate 70, which are controlled by the PCB mainboard 20 and can emit different colors of light such as red, green, blue, etc. The number, position and color of the LED lights can be adjusted according to needs to achieve different light-emitting effects. On the surface or inside of the light guide plate 70, specific graphic logos can be designed, which can be brand logos, product models, decorative patterns, etc., made on the light guide plate 70 by laser engraving, silk-screen printing, heat transfer printing or other processes. When the light source is turned on, the light will propagate along the inside or surface of the light guide plate 70 and illuminate these graphic logos, making them present a bright and uniform light-emitting effect.

[0044] More specifically, by emitting different graphic logos, the power bank not only visually attracts the attention of users, but also enhances the overall aesthetics and technological feel of the product. This design makes the product more competitive in the market and may stimulate the user's desire to purchase. In addition, displaying brand logos or product models and other graphic logos on the light guide plate 70 helps to improve brand recognition and popularity. When users use or display the product, these logos can play a role in promotion and promotion. In addition, the light-emitting display function not only improves the practicality of the product, but also provides users with a more rich user experience by adding visual elements and interactivity, which makes the product not only meet the basic charging needs, but also has higher added value and attractiveness.

[0045] In an embodiment, the shell 10 located on the outside of the light guide plate 70 is also provided with a decorative sheet 80.

The shape and size of the decorative sheet 80 match the back of the shell 10 to ensure that it can be tightly attached to the shell 10 and cover the light guide plate 70. The decorative sheet 80 can be fixed to the shell 10 in various ways, such as using double-sided tape, hot melt glue, screws, or snap connections, etc. During installation, the gap between the decorative sheet 80 and the shell 10 should be as small as possible to avoid light leakage or affect the lighting effect. At the same time, attention should be paid to maintaining the flatness and cleanliness of the decorative sheet 80 to ensure that it can clearly display the graphics logo and lighting effect on the light guide plate 70. The decorative sheet 80 not only serves as a decorative element, but also protects the light guide plate 70 from scratches, impacts, or contamination, etc., extending its service life. At the same time, the decorative sheet 80 can also enhance the brightness and uniformity of the lighting effect, making the graphics logo more vivid and lively.

[0047] More specifically, the transparent decorative sheet 80 can further enhance the lighting effect of the light guide plate 70, making the graphics logo brighter and clearer; at the same time, the transparent texture and smooth surface of the decorative sheet 80 can also improve the overall aesthetics and technological feel of the product. In addition, by setting the transparent decorative sheet 80, the light guide plate 70 can be effectively protected from scratches, impacts, etc., extending its service life, which is particularly important for mobile power supplies that need to be frequently carried and used.
