Abstract

The embodiment of the invention provides a touch display device and a household electrical appliance, and belongs to the field of household electrical appliances. The device comprises a display modulecomprising a display panel configured to display; and a sensing spring configured to wind the display module by using a direction perpendicular to the display panel as an axis, thus allowing capacitance on the sensing spring to be changed when the touch display device is touched. Touch on the display module is detected by the sensing spring on which the capacitance can be changed when the displaymodule is touched, the technical scheme of the device is applicable to various display modules, and compared with an ITO film, the sensing spring has a larger physical size and good mechanical performance which is specially owned by metal material, so that the device is convenient to mount and low in cost.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a touch display device and a household appliance. Background technique [0002] Existing application interfaces of home appliances include buttons, icon displays, knobs, gestures, etc. to realize user operation functions, among which touch and icon display methods are currently more popular and have better user experience effects. In home appliances, LCD or LED are often used for display, and then a layer of ITO film is pasted on the display interface. When the icon on the display interface is touched by the human hand, the capacitance value of the corresponding transparent button on the ITO film changes. After the chip receives the change of the ITO film button, it makes corresponding processing. [0003] In the application interface composed of transparent ITO film and display icons, since the ITO film is transparent, the user cannot see the ITO film, so when the user's fin...
