It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
With the increase of economic development and living standard, consumers have increasingly demanded home appliances such as water heaters and water purifiers, and in order to facilitate user operation, a display device is generally installed on the home appliances as an operation interface, however, in the related art, display images on the home appliances are less and single.
The application provides a full-screen display device and a household appliance, which are used for solving the problems of fewer display pictures and single display on the household appliance in the related technology.

The spray painting layer 20 is formed on the transparent substrate 10, the spray painting layer 20 at least comprises a background pattern 21 and a touch pattern 22, and the background pattern 21 and the touch pattern 22 are transparent. It can be understood that the spray-painting layer 20 can be formed on the light incident side or the light emitting side of the light-transmitting substrate 10, and the light emitted by the backlight module 40 can be transmitted through the background pattern 21 and the touch pattern 22 on the spray-painting layer 20 to illuminate the background pattern 21 and the touch pattern 22, so that the user can clearly view the background pattern 21 and the touch pattern 22, and the pattern formed by spray-painting has the advantages of vivid color, high saturation, and the like, thereby facilitating the clear display of the background pattern 21 and the touch pattern 22. Wherein, the light emitted by the backlight module 40 is emitted into the transparent substrate 10 from the light incident side of the transparent substrate 10; the background pattern 21 may be at least one of a earth pattern, a moon pattern, a lake surface pattern, and the like, and may improve the screen richness when the display device displays the image; the touch pattern 22 may be at least one of an on/off control pattern, a temperature control pattern, a time control pattern, a mode control pattern, etc., and the touch pattern 22 may be used to instruct a user to touch at a corresponding position of the full screen display device to perform on/off control, temperature control, time control, and mode control adjustment, so that the user can conveniently and accurately adjust, for example, the user may touch an area of the full screen display device where the touch pattern 22 is located to implement on/off of the full screen display device.
The light shielding layer 30 is disposed on the inkjet layer 20 or the light-transmitting substrate 10, and the light shielding layer 30 includes a light-transmitting region corresponding to the background pattern 21 and the touch pattern 22; it can be understood that the light shielding layer 30 may be disposed on a side of the transparent substrate 10 away from the inkjet layer 20, and the light shielding layer 30 may also be disposed on a side of the inkjet layer 20 away from the transparent substrate 10, where the light shielding layer 30 is used for shielding an area (such as the background pattern 21 and the peripheral edge area of the touch pattern 22) of the inkjet layer 20 that does not need to be light-transmitting, and meanwhile, the light-transmitting area can transmit light, so that the background pattern 21 and the touch pattern 22 can be normally displayed under illumination of light, and when the background pattern 21 is normally illuminated, for example, the light of the peripheral edge area of the background pattern 21 is shielded by the light shielding layer 30, so that a clear contrast is formed between the area where the background pattern 21 is located and the peripheral edge area of the background pattern 21, thereby making the display of the background pattern 21 more clear. The preparation material of the light shielding layer 30 may be black ink, black resin, light shielding tape, etc., and the preparation material of the light shielding layer 30 is not particularly limited in the present application; the light shielding layer 30 may be formed on the inkjet layer 20 or the transparent substrate 10 by a process such as screen printing, spraying or pasting, and the preparation process of the light shielding layer 30 is not particularly limited in the present application.
The backlight module 40 is disposed on the light incident side of the transparent substrate 10, and the light emitted from the backlight module 40 can be transmitted through the transparent substrate 10, the background pattern 21, the touch pattern 22 and the transparent area to illuminate the background pattern 21 and the touch pattern 22. The backlight module 40 can provide light for the background pattern 21 and the touch pattern 22 to illuminate the background pattern 21 and the touch pattern 22.
It can be understood that in the application, when the full-screen display device works normally, the monotonous patterns such as the touch pattern 22 can be displayed, meanwhile, the esthetic background pattern 21 can be displayed, the display area of the full-screen display device can be fully utilized, so that the pictures displayed by the full-screen display device are more colorful, and when the full-screen display device is applied to a household appliance, the super-real large-color screen effect can be simulated in the household appliance.

In an embodiment of the present application, the transparent conductive member 81 includes at least one of a conductive silver paste layer, an indium tin oxide layer and a conductive resin layer, so that the transparent conductive member 81 has high light transmittance, and light emitted from the backlight module 40 can pass through the transparent conductive member 81 and irradiate on the inkjet layer 20, so that the pattern on the inkjet layer 20 becomes brighter and more visible, and a user can distinguish the pattern on the inkjet layer 20 conveniently.
With continued reference to fig. 8 and 9, in an embodiment of the application, the backlight module 40 may include a lamp panel bracket 41, a lamp panel 42, and a plurality of lamp sources 43.
Wherein the lamp panel bracket 41 is disposed between the electric control board 82 and the light-transmitting substrate 10; the lamp panel 42 is disposed between the lamp panel bracket 41 and the transparent substrate 10 and electrically connected to the electric control board 82; the plurality of light sources 43 are disposed on the light plate 42 and electrically connected to the light plate 42, and the light sources 43 are disposed towards the light-transmitting substrate 10 and spaced apart from the light-transmitting substrate 10; the elastic conductor 83 passes through the lamp panel holder 41.
The lamp panel bracket 41 mainly plays a supporting role, and the elastic conductor 83 passes through the through hole on the lamp panel bracket 41 to be electrically connected with the main control board, so that the unstable electrical connection between the elastic conductor 83 and the main control board and between the elastic conductor 83 and the transparent conductive piece 81 caused by the position deviation of the elastic conductor 83 can be avoided. The light source 43 is disposed on the light plate 42, and the light emitted by the light source 43 irradiates the pattern on the spray layer 20 through the transparent conductive member 81.

The white coating is added on the lamp panel 42 to reflect the light emitted by the lamp source 43, so that most of the light emitted by the lamp source 43 is emitted to the transparent substrate 10, and the light utilization rate is improved.
The white coating can be a reflective paint coating, and the reflective principle of the reflective paint coating is that the reflective paint contains a large number of reflective microbeads, so that the irradiated light can be reflected back through the reflective microbeads, and a good reflective effect is formed.
Based on the above-mentioned full screen display device, the application also provides a household appliance, which comprises a household appliance body and the display device according to any embodiment, wherein the display device is arranged on the household appliance body.
