Through the cooperation of the light guide frame and the LED light source 13, the double-sided display 1 can form a full halo structure without black borders; specifically, it can form a full atmosphere light structure with no black borders on all sides and a colorful light effect.

[0033] It should be noted that halo refers to a name in the display industry for the atmosphere light effect formed on the front, sides and back of the display. According to the different positions of the atmosphere light, it is divided into Front, Edge, Halo, etc. The full halo structure in the utility model refers to the formation of atmosphere lights all around the front and back sides of the double-sided display 1.

[0034] The light guide frame in the utility model has a certain light transmittance and a certain light diffusion rate. By adjusting these two parameters, light guide frames of different widths and thicknesses can be made, so that the ambient light emitted by the light guide frame is more uniform and soft.

[0035] like Figure 1-3 As shown, the light guide frame includes a U-shaped light guide bar 4 and an I-shaped light guide bar 5. The overall structure of the U-shaped light guide bar 4 is U-shaped, and can be specifically formed by three separate straight-line light guide bars integrally formed. The use of the integrally formed U-shaped light guide bar 4 has the advantages of being easy to manufacture, easy to install, and having high structural strength. However, as needed, three separate straight-line light guide bars can also be used to replace the integral structure. The U-shaped light guide bar 4 is fixed to the upper side, left side, and right side of the double-sided display 1 at the same time, and simultaneously blocks the non-display area on the upper side, left side, and right side of the front and back sides of the double-sided display 1.
