Display operation interface structure of household electrical appliance

Abstract

The invention discloses a display operation interface structure of a household electrical appliance. The structure comprises an appearance part, a touch key and a PCB assembly arranged on the inner side of the appearance part. The display operation interface structure is characterized in that a window paster is arranged on the external side of the appearance part; at least two spaced content displaying areas are formed on the window paster; first perforations corresponding to the content displaying areas are formed in the appearance part; the first perforations are alternately arranged; the touch key is arranged between the window paster and the appearance part and at least partially corresponds to the content displaying areas; and the PCB assembly has at least two LED lamps corresponding to the first perforations. To-be-displayed contents are formed on the paster, the perforations are alternately formed in the appearance part and the LED lamps are corresponding to the perforations, so the LED lamp light can be isolated by the appearance part and light scattering and light crosstalk can be avoided for the light due to the window paster; and therefore, adjacent displayed contents can be clearly and completely displayed.

Description

technical field [0001] The invention relates to the field of touch display, in particular to a display operation interface structure of household appliances. Background technique [0002] At present, when the display interface in the market is not working, the interface and display content are hidden and not displayed, and are displayed only when the power is on or in the working state. [0003] In the existing implementation methods, the content displayed in some schemes is very blurred; some schemes require the use of liquid crystal display screens, and the display area cannot be well combined with other areas, resulting in obvious color difference. [0004] In addition, there are other options such as figure 1 and figure 2 As shown, among them, figure 1 The realization structure shown is from top to bottom a transparent part 1', a light guide paint 2', a diaphragm 3' and an LED light 4', and the diaphragm 3' has a light-transmitting light that presents the content to ...

Problems solved by technology

[0005] Among them, in figure 1 In the scheme, after the light emitted by the LED lamp 4' passes through the light-transmitting part 31' on the diaphragm 3', severe scattering will occur at the light guide paint 2' and the transparent part 1', resulting in the final displayed content more vague; and figure 2 In the proposed solution, the light emitted by the LED lamp 4" will be severely scattered when passing through the transparent plastic part 3", causing the light emitted by the LED lamp 4" not only to pass through the corresponding light-transmitting part 21", but also from the adjacent The light-transmitting part 21” leaks, and there is a serious cross-light problem, that is, when one of the two adjacent display contents lights up, the other has light coming out at the same time
