Multilayer display device and washing machine employing same

Abstract

The invention relates to the field of washing machine display equipment, and specifically relates to a multilayer display device and a washing machine employing the same. The multilayer display device comprises a controller, a light source, a liquid crystal layer and a display unit, and the light source, the liquid crystal layer and the display unit are sequentially arranged. The display unit comprises at least two sub display layers which have different refractive indexes and are mutually superposed, each sub display layer can reflect or be penetrated by light rays in a specific wavelength scope, the sub display layers display different control interfaces, and the controller controls the different control interfaces to be displayed on the different sub display layers. By employing the multilayer display device, space can be effectively saved, characters on the control interfaces are relatively amplified, and old people can use the multilayer display device conveniently; different sub display layers are different in color, and each control interface can be distinguished visually and easily.

Description

technical field [0001] The invention relates to the field of washing machine display equipment, in particular to a multilayer display device and a washing machine using the device. Background technique [0002] Existing washing machines are generally equipped with a control panel on the front top or top of the casing, and the working state of the washing machine to be used is set through the control panel. For example, before using the washing machine, the washing program is set through the control panel. Function, water level, time and other parameters. The control panel is provided with multiple display windows for displaying various control interfaces. The control interfaces mainly include program control interface, function control interface, water level control interface and time control interface. [0003] However, in the prior art, all the control interfaces of the washing machine, such as the program control interface, function control interface, water level control...

Problems solved by technology

[0003] However, in the prior art, all the control interfaces of the washing machine, such as the program control interface, function control interface, water level control interface, and time control interface, contain icons that are independently arranged on the display window or display screen, that is, display Icons can only be displayed in a parallel arrangement on the window

[0004] Due to the limited area of ​​the display window, the space occupied by each icon is limited, which will inevitably lead to the fact that the font of each icon cannot be too large, and the height of each font can only be smaller than a certain value, so the font on the icon is too small

Since many old people use washing machines, their eyesight may not be very good, so it will inevitably lead to the old people not being able to see the fonts on the display window clearly when using the washing machine, which will cause a lot of trouble and is not convenient for the old people to use.

[0005] And as the program functions of the washing machine continue to enrich, the number of icons that need to be displayed on the display interface also continues to increase, resulting in the need to increase the area of ​​the display window to achieve the problem of arranging more icons. increase, it will inevitably cause the need to increase the space of the computer board, and at the same time arrange so many icons on the display window at the same time, it will also increase the complexity of the display window

[0006] Based on the above description, a new washing machine display device is urgently needed to solve the problems in the prior art that the washing machine computer board has more and more functions and takes up a lot of space, and the font on the display window of the washing machine is currently small. Inconvenience for the elderly
