The target sterilization area is the surface of the cover plate 46.
Fig. 5 is a schematic structural diagram of a display device according to still another embodiment of the present invention.
Referring to fig. 5, the display device includes a display screen 51, a backlight 52 disposed on a non-light-emitting surface side of the display screen 51, and a frame structure 53a and a frame structure 53b symmetrically disposed between the display screen 51 and the backlight 52, where the frame structure 53a and the frame structure 53b are used to fix the display screen 51 and the backlight 52.

The inventor considers that in the above embodiments shown in fig. 3 and 4, the auxiliary plate and the reflection plate are integrally formed, so when the reflection auxiliary structure is designed, the angle α is a fixed angle, and cannot be adjusted according to the position and size change of the target sterilization area. Therefore, the inventors have studied and further proposed improvement measures.
Specifically, unlike the embodiment described above with reference to fig. 3 and 4, in this embodiment, the reflecting plate 54a and the top of the auxiliary plate 54b are connected by a rotatable structure 57, wherein the position of the auxiliary plate 54b is still fixed, and the reflecting plate 54a can rotate around the rotatable structure 57 to adjust the angle α. Wherein the adjustable range of the angle alpha is 90-150 degrees. Wherein the rotatable structure 57 is a hinge or other component that can rotate the reflection plate 54 a.
In this embodiment, since the reflection plate 54a is rotatable around the rotatable structure 57, the angle α between the reflection plate 54a and the auxiliary plate 54b can be adjusted according to the position and size of the target sterilization area, so as to adjust the angle at which the ultraviolet light emitted by the ultraviolet light source 55 is reflected by the ultraviolet light reflection coating 541 on the reflection plate 54a and then irradiates the target sterilization area of the display screen 51.
It should be noted that, in the above embodiments, the display device shown in fig. 1 to 5 only includes one ultraviolet light source, and the ultraviolet light source is disposed on the left side of the display screen, but in practical application, the number of the ultraviolet light sources may be determined according to the position and size of the sterilization and disinfection area, and if a plurality of ultraviolet light sources are disposed, the ultraviolet light sources may be disposed on the same side of the display screen or disposed on a plurality of sides of the display screen respectively. In addition, the display devices shown in fig. 1 to 5 only include one reflection auxiliary structure, but in practical applications, the number and the positions of the reflection auxiliary structures need to be determined according to the number and the positions of the ultraviolet light sources, and corresponding reflection auxiliary structures need to be arranged on the side surfaces of the display screen provided with the ultraviolet light sources. Accordingly, fig. 1 to 5 are only schematic diagrams and do not limit the present invention.
In all the above embodiments, the ultraviolet light reflective coating on the reflective plate may be a semiconductor coating or an aluminum oxide coating. The ultraviolet light emitted by the ultraviolet light source is short wave, and the wavelength range of the ultraviolet light can be 200-280 nanometers. The display screen can be a liquid crystal display screen or an OLED display screen. When the display screen is an OLED display screen, a backlight source is not needed. The ultraviolet light source can be an ultraviolet LED light source or an ultraviolet lamp tube light source.
In all the embodiments described above, the arrangement of the components in the display device can be arbitrarily combined without contradiction, and the structure of the display device obtained by the combination is all included in the protection scope of the present invention.
In conclusion, the display device provided by the technical scheme can realize the effect of automatically sterilizing and disinfecting the surface of the display screen in the display device.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
