Abstract

The invention discloses a liquid crystal display device dedicated for an extractor hood. The liquid crystal display device dedicated for the extractor hood comprises a rectangular aluminium alloy panel and an aluminium alloy shell, wherein the rectangular aluminium alloy panel and the aluminium alloy shell are in buckled connection; the outer surfaces of the aluminium alloy panel and the aluminium alloy shell are coated with a protective film, wherein the protective film comprises the following components in parts by weight: 0.9 part of ethylene glycol, 0.4 part of heptadecenyl imidazoline alkenyl succinate, 8-9 parts of nanometer silicon resin, 1-2 parts of catechol, 2-3 parts of sodium dodecyl benzene sulfonate emulsion, 1-2 parts of divinylbenzene, 1.3 parts of alkylolamides polyethylene oxide epoxyethane ether and 0.8 part of calcium stearate. The liquid crystal display device has peculiar display design, structure design and protection design; the outer surfaces of the panel and the shell are coated with the protective film to prevent the aluminium alloy panel and the aluminium alloy shell from being corroded, and a liquid crystal display control circuit board is prevented from being damped or corroded for a long time.

Description

technical field [0001] The invention relates to a liquid crystal display device specially used for range hoods. Background technique [0002] At present, the range hood is often equipped with a liquid crystal display device, and the liquid crystal display in the liquid crystal display device needs a liquid crystal display control circuit board to drive and control it.
