When the display screen works, the lamp beads on the backlight module 8 emit light to serve as a light source to provide enough light, and the light passes through the multi-layer light guide or light equalizing membrane in the light guide structure 7, so that the light is uniformly projected onto the TFT FOG6, and the brightness of each area is uniform when the screen is displayed.
In particular, the display screen with the existing structure cannot be lightened in the adhesive area due to the fact that backlight is not arranged, and can only exist as a black edge area. In the side region of the vehicle-mounted display screen, light is projected onto the light guide structure adhesive 3 from the side surface of the light guide structure 7, and the light is projected onto the side region of the TFT FOG6 by refraction of the light guide structure adhesive 3. On the premise that enough adhesive area is available for fixing the TFT FOG6, the TFT FOG6 can be lightened as a display area in the adhesive area by the aid of the light guide capability of the light guide structural adhesive 3, so that the area of the display area is enlarged, and an ultra-narrow frame 5 is formed. The schematic of the light path is shown in fig. 5.

Preferably, the frame 5 is made of high-strength metal or composite material, and the frame 5 is formed by integral bending, integral injection molding, or the like. The frame 5 is structured in the form of a reinforcing rib by bending or the like, so that the structural strength can be improved, thereby allowing a thinner thickness to be selected.
