The light source 4 includes a light source capable of emitting ultraviolet light or visible light. The light source 4 irradiates on the display unit 3 containing special materials, and can display preset corresponding contents, so that the purpose of displaying is achieved.
The display unit 3 may be a display panel or a display sheet, and the display coating is coated on the display unit 3 to form a plurality of preset display contents. The display content can be set according to the working program of the specific household appliance, and the display content comprises all forms, such as characters, numbers, patterns and the like, which can show the selected program and program process to the user.
The display coating layer of the display unit 3 contains a plurality of fluorescent substances, printing inks, and the like that form different predetermined display contents, and also includes other structures that form the display unit 3, such as film lamination, and the like. Fluorescent substances include, but are not limited to, fluorescent whitening agents, fluorescent inks, and fluorescent powders. The preset multiple different display contents can be formed by coating multiple fluorescent substances in the display unit 3 layer by layer or in a mixed manner, and when the light source 4 irradiates on the display unit 3, the corresponding fluorescent substances can be excited to display the corresponding display contents; or the preset display content is formed by printing ink and the like, and when visible light is transmitted or mapped, the corresponding preset display content can be displayed. If ultraviolet light with short wavelength is used, substances for blocking or absorbing ultraviolet light are required to be added to the display unit 3 without fluorescent substances, so as to reduce ultraviolet leakage and prevent the influence on human body.
The position of the light source 4 can be set according to the specific structure of the household appliance, and the light source is arranged on the front or back of the display unit 3, can be arranged in the body of the appliance, and also can be arranged outside the body, as long as the light source can correspondingly irradiate the display coating to display images, and can be conveniently adjusted in real time, and accurately display the program function of the household appliance.
Different light sources 4 can individually illuminate the same position of the display coating to display the corresponding image; alternatively, multiple light sources 4 may illuminate the same location of the display coating simultaneously to display the superimposed image.
When the display coating is irradiated by the multiple light sources 4 independently, if the light sources 4 emit ultraviolet light, the region containing the fluorescent substance can be excited to emit a fluorescent phenomenon, and corresponding colors and contents are displayed; if the light source 4 emits visible light, the visible light can be transmitted or mapped to the same region to display a corresponding color and content different from those of the light irradiated by the ultraviolet light. When the multiple light sources 4 output simultaneously and irradiate the display unit 3, the displayed color is the color of the synthesized light, and the content is the superposition display of multiple characters and/or patterns, so the displayed color and content are rich and colorful. Therefore, the more light sources 4 are added, the more colors and contents can be changed and displayed in the same display area, the display space can be saved, the display contents and colors can be enriched, the display cost is low, and the display device is suitable for common household appliances.
Further, the light source 4 includes a first light source capable of emitting ultraviolet light and a second light source capable of emitting visible light; and a display unit 3, wherein the display unit 3 comprises a display coating layer which forms a plurality of preset display contents. The visible light emitted by the second light source is preferably red or green light.
