Description

Display control panel, preparation method of display control panel and household appliance Technical Field The invention relates to the technical field of household appliances, in particular to a display control panel, a preparation method of the display control panel and household appliances. Background This section provides merely background information related to the present disclosure and is not necessarily prior art. The home appliance is usually provided with a display control panel, and the display control panel is used for displaying parameters of the home appliance. In the process of manufacturing the display and control panel, through holes are usually formed in a base material, resin materials are filled in the through holes, a filled plate is obtained, and the filled plate is used for processing the display and control panel. However, when the through-hole is of a microporous structure, efficient filling of the through-hole cannot be achieved when filling the resin material into the through-hole. Disclosure of Invention An object of an embodiment of the present invention is to at least solve the problem that efficient filling of the through-holes cannot be achieved when filling the resin material into the through-holes of the microporous structure. The aim is achieved by the following technical scheme: A first aspect of an embodiment of the present invention provides a method for manufacturing a display control panel, including: Providing a substrate having a through hole; Providing a semi-cured adhesive film with a first release film and a second release film respectively arranged at two sides, wherein the semi-cured adhesive film comprises a resin material; Removing the first release film from the semi-cured adhesive film and arranging the first release film on one side of the base material, wherein the semi-cured adhesive film is attached to the base material; Filling the semi-cured adhesive film from the other side of the base material to the inside of the through hole through a hot pressing process, wherein the second release film is arranged away from the base material; and curing the semi-cured adhesive film to obtain the plate for manufacturing the display control panel.
