[0022] In the embodiment of the present application, through the outer frame 1, the first glass 2, the second glass 3, the display screen assembly 4 and the back cover 5, the first glass 2 is embedded in one end face of the outer frame 1, and the back cover 5 is arranged on the other end face of the outer frame 1; the second glass 3 is arranged on the side of the first glass 2 facing the back cover 5, and a waterproof strip 6 is arranged between the second glass 3 and the outer frame 1, and an installation cavity 7 is formed between the second glass 3, the waterproof strip 6 and the outer frame 1, and the display screen assembly 4 is installed in the installation cavity 7. By arranging the first glass 2 and the second glass 3 on the front side of the display screen assembly 4, a double-layer glass protection is formed, and the waterproof strip 6 is arranged between the second glass 3 and the frame, which directly prevents the entry of water fog on the one hand, and on the other hand, a stepped structure with a high outside and a low inside is formed between the first glass 2 and the second glass 3, thereby improving the water fog blocking effect; at the same time, the double glass design also has the functions of heat insulation, heat preservation, noise reduction, and isolation of ultraviolet light, which can improve the service life of the electronic display screen; by arranging the back cover 5 on the back of the outer frame 1, when maintenance is required, it is only necessary to open the back cover 5 without disassembling the entire display assembly. The electronic advertising screen of the present application has a simple structure, good anti-fog effect, convenient and quick maintenance, and strong practicality.

[0023] Next, the electronic advertising screen in this exemplary embodiment will be further described.

[0024] In the embodiment of the present application, the first glass 2 is embedded in one end face of the outer frame 1, and the back cover 5 is arranged on the other end face of the outer frame 1; the second glass 3 is arranged on the side of the first glass 2 facing the back cover 5, that is, the first glass 2 is located outside the second glass 3, and the first glass 2 and the second glass 3 form a double-layer protective barrier for the display screen assembly 4; a waterproof strip 6 is arranged between the second glass 3 and the outer frame 1, and a mounting cavity 7 is formed between the second glass 3, the waterproof strip 6 and the outer frame 1, and the display screen assembly 4 is installed in the mounting cavity 7. By arranging the waterproof strip 6 between the second glass 3 and the outer frame 1, a stepped structure with a high outside and a low inside is formed between the second glass 3 and the end of the first glass 2, so that when the water mist passes through the gap between the first glass 2 and the frame, the water mist will not enter the mounting cavity 7 under the blocking of the second glass 3 of the waterproof strip 6, so as not to affect the display screen assembly 4; at the same time, the design of double-layer glass can also effectively block the entry of external ultraviolet rays, and play the role of heat insulation, heat preservation, noise reduction, etc.

[0025] As an example, the outer frame 1 is formed by connecting four side frames, and the longitudinal section of the side frame is U-shaped. The open end of the side frame close to the first glass 2 is inclined toward the first glass 2 and abuts against the first glass 2, that is, the first glass 2 is covered on the inner wall of the outer frame 1, and the open end of the outer frame 1 abuts against the first glass 2. Water mist moves downward along the inclined outer frame 1 and is not easy to enter the interior from between the first glass 2 and the outer frame 1; the other side of the first glass 2 abuts against one side of the waterproof strip 6. If water mist enters from between the outer frame 1 and the first glass 2, it will be blocked by the abutment between the waterproof strip 6 and the first glass 2, further improving the anti-fog effect.

[0026] As an example, an embedding groove is opened at one end of the waterproof strip 6 away from the frame, and the second glass 3 is embedded in the embedding groove and fixed, that is, the two sides of the second glass 3 are in contact with the waterproof strip 6, forming a strong sealing effect, and together with the waterproof strip 6, forming a second protective barrier.

[0027] As an example, a mounting groove is provided on the outer wall of the frame away from the first glass 2, the depth of the mounting groove is adapted to the thickness of the back cover 5, and the back cover 5 is arranged in the mounting groove and is detachably connected via a connector. Specifically, the connector may be a bolt, and the back cover 5 is embedded in the mounting groove during installation or removal, and is fixed by tightening the bolts. When the display assembly needs to be repaired, the back cover 5 can be removed directly by removing the bolts, and the display assembly 4 can be repaired from the back without removing the display assembly 4 as a whole, which is simple and quick to operate.

[0028] In the embodiment of the present application, the display screen assembly 4 includes a display module 41 and a module mounting plate 42. The display module 41 is mounted on a side of the module mounting plate 42 away from the back cover 5, and the module mounting plate 42 abuts against the other side of the waterproof strip 6. The module mounting plate 42 is provided with a first support plate 43 and a second support plate 44 at one end facing the waterproof strip 6, and the waterproof strip 6 is located between the first support plate 43 and the second support plate 44. By providing two opposite first support plates 43 and second support plates 44 at the end of the module mounting plate 42, the waterproof strip 6 is located between the first support plate 43 and the second support plate 44, and the module mounting plate 42 abuts against one side of the waterproof strip 6, so that the module mounting plate 42, the first support plate 43 and the second support plate 44 form a support for the waterproof strip 6, and at the same time, jointly form a third barrier for the display module 41. When water mist enters the waterproof strip 6 through the first glass 2, due to the sealing effect of the waterproof strip 6, the second support plate 44, and the module mounting plate 42 abutting against the waterproof strip 6, the water mist is difficult to enter the display module 41 below, thereby further improving the anti-fog effect.

[0029] As an example, the waterproof strip 6 is provided with grooves on the side facing the first support plate 43 and the side facing the module mounting plate 42, so that the waterproof strip 6 has a certain extrusion elasticity, making the seal tighter and reducing the weight at the same time.

[0030] As an example, the module mounting plate 42 is provided with a plurality of cooling fans on one side facing the back cover 5, and the back cover 5 is provided with a plurality of cooling holes 51 corresponding to the cooling fans. The heat of the display components can be dissipated from the back cover 5 through the cooling fans and the cooling holes 51.

[0031] As an example, the module mounting plate 42 is provided with an electronic module on one side facing the back cover 5, the back cover 5 is provided with a window corresponding to the electronic module, and the window is provided with a cover plate 52. By providing the window and the cover plate 52 on the back cover 5, the cover plate 52 can be fixed to the window in a buckling manner, and when the electronic module needs to be inspected, the cover plate 52 can be directly opened, which is convenient and quick to operate.
