Abstract

The invention discloses a liquid crystal display device for a range hood. According to the liquid crystal display device, a sealant is arranged at multiple positions and consists of the following components in parts by weight: 0.2 part of quartz flour, 3-4 parts of gas phase silicon dioxide, 1-2 parts of tetrahydrofuran, 2-3 parts of diaryl secondary amine, 2-3 parts of gas phase white carbon black, 1-2 parts of 2,2,4-trimethyl-1,2-dihydroquinoline, 22 parts of dimer acid modified epoxy resin, 2-3 parts of glycerol monostearate and 1-2 parts of isopropanolamine. The liquid crystal display device for the range hood, disclosed by the invention, is unique in display design, structural design and protective design; and the sealant is arranged at multiple positions to ensure that a liquid crystal display control circuit board cannot be damped and corroded for a long time, and can work effectively for a long time. The sealant can resist a high temperature of 100 DEG C and a low temperature as low as -24 DEG C.

Description

Technical field [0001] The invention relates to a liquid crystal display device for a range hood. 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 liquid crystal display device for range hoods, which has unique display design, structural design and protection design; its aluminum alloy panel and aluminum alloy outer casing are firmly connected, and will not be separate...
