In order to improve brightness uniformity of a background pattern of a display device, as shown in fig. 1 to 5, an embodiment of the present disclosure provides a display device including a display panel 100, a display film 200, and a light shielding member 300. Wherein the display panel 100 is provided with an icon light source 110 and a background light source 120. The display film 200 is opposite to the display panel 100, and the display film 200 is provided with an icon display pattern 210 corresponding to the icon light source 110 and a background display pattern 220 corresponding to the background light source 120. The light shielding member 300 is disposed between the display panel 100 and the display film 200, and the light shielding member 300 defines an icon light channel 301 and a backlight light channel 302 isolated from each other. The light emitted from the icon light source 110 illuminates the icon display pattern 210 of the display film 200 through the icon light channel 301. The light emitted from the backlight 120 illuminates the background display pattern 220 of the display film 200 through the backlight channel 302.

In the embodiment of the disclosure, the display device may be installed in different home appliances to display operation information of the appliances. For example, the display device is mounted on a refrigerator, and displays information such as a refrigerating temperature, a freezing temperature, and power consumption of the refrigerator.

The display device includes a display panel 100 and a display film 200. The display panel 100 is provided with a light source, and light emitted from the light source is projected to the display film 200, thereby allowing a user located at the other side of the display film 200 to observe display information.

Further, the display panel 100 is provided with an icon light source 110 and a background light source 120, and the display film 200 is provided with an icon display pattern 210 and a background display pattern 220. Icon light source 110, when illuminated, illuminates icon display pattern 210 and background light source 120, when illuminated, illuminates background display pattern 220.

To avoid that the icon light source 110 and the background light source 120 interfere with each other, i.e. to avoid that the icon light source 110 illuminates the background display pattern 220 or the background light source 120 illuminates the icon display pattern 210, the display device further comprises a shading assembly 300. The light shielding member 300 is disposed between the display panel 100 and the display film 200, and defines an icon light channel 301 and a backlight channel 302 isolated from each other. The icon display pattern 210 is illuminated by light from the icon light source 110 along the icon light path 301 and the background display pattern 220 is illuminated by light from the background light source 120 along the background light path 302. Thus, the display information of the display device can be controlled by controlling the on-off states of the icon light source 110 and the background light source 120.

The first end of the shade cartridge 310 interfaces with the control surface and shields the at least one icon light source 110. A second end of the light shielding cylinder 310 interfaces with the display film 200 and shields at least one icon pattern. The light shielding tube 310 defines an icon light channel 301 therein, and when the icon light source 110 is lighted, the emitted light irradiates the icon pattern along the icon light channel 301, thereby lighting the icon pattern. By adopting the arrangement mode, the structure is simple and light leakage is not easy to occur.

The outside of the light shielding cylinder 310 serves as the backlight channel 302. The external display panel 100 of the light shielding cylinder 310 is provided with at least one backlight 120. When the background light source 120 is lighted, the emitted light is irradiated to the background pattern from the outside of the light shielding cylinder 310, so that the display device can display the background pattern.

The separation of the icon light source 110 and the background light source 120 can be achieved at low cost with the inside of the light shielding cylinder 310 as the icon light passage 301 and the outside of the light shielding cylinder 310 as the icon light passage 301.

Alternatively, the light shielding cylinder 310 is fixed to the display panel 100.

With such an arrangement, the light shielding assembly 300 is advantageously abutted to the display panel 100, thereby reducing the risk of light leakage from the light shielding barrel 310.

Alternatively, the light shielding cylinder 310 is integrally formed with the display panel 100.

This enables the light shielding tube 310 to be seamlessly abutted with the display panel 100, thereby further reducing the risk of light leakage of the light shielding tube 310.

Optionally, the light shielding assembly 300 further includes a first reflective film disposed on an inner wall of the light shielding barrel 310.

The reflective film may reflect most of the light, and the first reflective film disposed on the inner wall of the light shielding tube 310 may effectively reflect the light emitted from the icon light source 110 to the icon display pattern 210, thereby improving the effective utilization rate of the light emitted from the icon light source 110.

Optionally, the light shielding assembly 300 further includes a second reflective film disposed on an outer wall of the light shielding barrel 310.

The second reflective film is disposed on the outer wall of the light shielding tube 310, so that the light emitted from the background light source 120 can be effectively reflected to the background display pattern 220, thereby improving the utilization rate of the light emitted from the background light source 120.

Accordingly, the shade assembly 300 further includes a base plate 320, and the shade tube 310 is fixed to the base plate 320. The bottom plate 320 is provided with a plurality of light holes 321 corresponding to the background light source 120 and the pattern light source, light emitted by the background light source 120 enters the background light channel 302 through the light holes 321, and light emitted by the icon light source 110 enters the icon light channel 301 through the light holes 321. With such an arrangement, the fixation of the shade tube 310 is facilitated.

Optionally, a third reflective film is provided on a side of the bottom plate 320 facing the display film 200.

The light emitted from the background light source 120 is more easily reflected to the background display pattern 220 by the reflection of the third reflection film. Light emitted from the icon light source 110 is more easily reflected to the icon display pattern 210. With such an arrangement, the effective utilization of the light emitted by the light source by the display device can be improved.

Optionally, a clamping portion is disposed at a first end of the light shielding barrel 310, and the clamping portion is clamped to a surface of the bottom plate 320 facing the display panel 100.
