Problems solved by technology

[0002] At present, the induction cooker is often equipped with a liquid crystal display device. The liquid crystal display in the liquid crystal display device needs a liquid crystal display control circuit board to drive and control. However, the operating environment of the induction cooker is relatively harsh, and it is in a humid environment with oily smoke for a long time. It is easy to make the liquid crystal display control circuit board be damp and Corroded, and the liquid crystal display control circuit board will affect the normal display of the liquid crystal display after being damp and corroded

Abstract

The invention discloses a liquid crystal display device specially used for induction cookers. The liquid crystal display device comprises a rectangular aluminium alloy panel and an aluminium alloy outer shell, which are connected by buckles, wherein the outer surfaces of the aluminium alloy panel and the aluminium alloy outer shell are coated with protective films; the protective films comprise the following components in parts by weight: 1.7 parts of propylene glycol, 1-2 parts of barium petroleum sulfonate, 15 parts of high-chlorinated polyethylene resin, 0.8 part of talcum powder, 1-2 parts of n-dodecanol ester, 2-3 parts of styrene-acrylic emulsion, 1-2 parts of ethylene glycol monostearate and 1.1 parts of zinc stearate. The liquid crystal display device has the advantages and beneficial effects that the liquid crystal display device has unique display design, structural design and protective design; the outer surfaces of the panel and the outer shell are coated with the protective films, thus preventing the aluminium alloy panel and the aluminium alloy outer shell from being corroded and ensuring liquid crystal display control circuit boards not to be affected with damp and corroded for a long term.

Description

technical field [0001] The invention relates to a liquid crystal display device specially used in an electromagnetic oven. Background technique [0002] At present, the induction cooker is often equipped with a liquid crystal display device. The liquid crystal display in the liquid crystal display device needs a liquid crystal display control circuit board to drive and control. However, the operating environment of the induction cooker is relatively harsh, and it is in a humid environment with oily smoke for a long time. It is easy to make the liquid crystal display control circuit board be damp and Corroded, and the liquid crystal display control circuit board will affect the normal display of the liquid crystal display after being damp and corroded. Contents of the invention [0003] The object of the present invention is to provide a liquid crystal display device specially used in an induction cooker, which has a unique display design, structural design and protection d...
