Novel liquid crystal display device capable of displaying timing clock and used for smoke exhaust ventilator

Abstract

The invention discloses a novel liquid crystal display device capable of displaying a timing clock and used for a smoke exhaust ventilator. The novel liquid crystal display device comprises a rectangular aluminum alloy panel and an aluminum alloy outer shell which are in buckle connection with each other, wherein protecting films are coated on the outer surfaces of the aluminum alloy panel and the aluminum alloy outer shell, and the protecting films comprise the following components by weight part: 0.6 parts of propylene glycol, 1-2 parts of barium soap of petrolatum oxide, 6-7 parts of nanometer silicon resins, 1-2 parts of sodium chloride, 2-3 parts of polycarboxylic sodium, 1-2 parts of alginic propylene glycol ester, 0.9 parts of dodecyltrimethylammonium and 1.1 parts of titanate. The novel liquid crystal display device provided by the invention has unique display design, structure design and protecting design; the protecting films are coated on the outer surfaces of the panel and the outer shell, so that the aluminum alloy panel and the aluminum alloy outer shell are prevented from being corroded, and a liquid crystal display control circuit board is prevented from being damped and corroded for a long term.

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...
