Abstract

The invention discloses a novel liquid crystal display device for a range hood capable of displaying a timing clock. The novel liquid crystal display device comprises a rectangular aluminum alloy panel and an aluminum alloy outer housing which are connected by a buckle, wherein the outer surfaces of the aluminum alloy panel and the aluminum alloy outer housing are coated with protective films; and each protective film comprises the following components in parts by weight: 0.5 part of dibutyl phthalate, 1-2 parts of methylbenzotriazole, 12 parts of bisphenol A type epoxy resin, 0.2 part of aluminum hydroxide, 1-2 parts of 2-(4-thiazolyl) benzimidazole, 1-2 parts of dimethylaminoethyl acrylate, 2-3 parts of dodecyltrimethylammonium sulfate and 1-2 parts of gamma-(methacryloxy) propyltrimethoxysilane. The novel liquid crystal display device disclosed by the invention has special display design, structure design and protection design; the outer surfaces of the panel and the outer housing are coated with the protective films, thereby preventing the aluminum alloy panel and the aluminum alloy outer housing from being corroded and ensuring that a liquid crystal display control circuit board cannot be moisturized and corroded for a long time.

Description

Technical field [0001] The invention relates to a novel liquid crystal display device for a range hood capable of displaying a timing clock. Background technique [0002] At present, the range hood 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. The use environment of the range hood is relatively harsh, and it is easy to control the liquid crystal display when it is in a humid environment for a long time. The circuit board is damp and corroded, and the liquid crystal display control circuit board is damp and corroded, which will affect the normal display of the LCD screen. Summary of the invention [0003] The purpose of the present invention is to provide a new type of liquid crystal display device for range hoods that can display a timing clock, which has a unique display design, structural design and protection design; its aluminum a...
