Abstract

The invention relates to a display device and a household appliance. A switch assembly and a light source are connected to a circuit board, and a user can control the light source to emit light of different colors through a specific circuit structure on the circuit board and the switch assembly. Meanwhile, according to the scheme, a plurality of polarizers with different light transmission types are stacked to be used as a polarizing plate. When light of different colors irradiates the polarizing plate, the light can pass through the polarizer matched with the light in light transmission typeand finally interact with a fluorescent layer to become white light, and then images or characters on the corresponding polarizer are displayed in a white form. By means of the scheme, when the lightsource emits light of different colors, different white images or character contents can be displayed in the area corresponding to the irradiation portion of the light source, in other words, multipledifferent contents can be displayed in the same display area. Therefore, the size of the display module can be effectively reduced, and the display module has the advantage of being high in display reliability.

Description

Technical field [0001] This application relates to the field of display technology, in particular to a display device and household electrical appliances. Background technique [0002] With the rapid development of science and technology, all kinds of home appliances are becoming more and more diversified and intelligent. The surface of the household electrical appliance is often provided with a display module to display the operating parameters and operating status of the household electrical appliance, so that the user can intuitively obtain the current operating status of the household electrical appliance and adjust the operating status of the household electrical appliance according to requirements. [0003] Traditional home appliances can only display one content in the same display area. When different content needs to be displayed, the controller needs to control the lighting of other display areas. This will cause the display module of the home appliance to be larger, whic...
