Industrial Open Frame Display 21.5inch Monitor with Separate Polarizer

21.5 Inch Open Frame Monitor with Separate Polarizer for Special ExhibitionThe full name of a polarizer is a polarizer. The imaging of a liquid crystal display must rely on polarized light. All liquid crystals have two front and rear polarizers closely attached to the liquid crystal glass to form a liquid crystal film with a total thickness of about 1mm. If any polarizer is missing, the liquid crystal can not display images. The polarizer facing the eyes of the liquid crystal display is frosted to dissipate the surface reflection and scatter the light to increase the viewing angle of the liquid crystal display. The principle of color liquid crystal display is similar to that of black and white display, but the structure is slightly changed, the control circuit is increased, and there are more pixels, and each pixel is independently controlled by a transistor. The light source used in color displays is generally placed inside the screen, and the light source passes through the liquid crystal from the inside to the outside to form a bright pattern.Product Features:-- 21.5 Inch 1920*1080 resolution, TFT panel, Fanless design.-- Open design frame,  support embedded / wall mount / panel mount,  etc.-- Wide operational temperature range, -10°C to +50°C-- Industrial grade which can work for 7*24 without interruption in harsh condition.-- Interface VGA Input: D-Sub15 pin, Optional Interface DVI, USB, HD-MI input.-- RoHS compliant.Product Specification  Model No.HSIM-2156LCD panel(IPS - Super TFT)Size21.5"Pixel numbers1920*1080Brightness250 nitsContrast Ratio500:1Viewing Angle178° (H)/178° (V)Colors 16.7MHardware Spec Interface VGA Input : D-Sub15 pinOptional InterfaceDVI.

All materials passed 100% IQC inspect. Before sending materials to the workshop and starting production, our IQC technicians will inspect them. And only qualified materials are approved to enter the workshop.2). We will do preproduction before bulk order to see the problem and solve them at the beginning.3). QC will inspect each product during production.4). Each production line team will be responsible by professional QC.5). All machines will be charged for playing 24/7 video.6). Environment high temperature testing. Suitable for temperature range of -10° to 60° C.We adhere to the "quality first, reputation first" service tenet, never use recycled raw materials, all of the raw materials from the world's top 500 supplier chain, such as Analog Devceies , Fairchild, ON Semiconductor, HRS, ST completely control supply chain. LCD module brand suppliers, such as Samsung, LG and AUO. These materials help to prevent the failure of consumer tablet computers. These projects can be used for 24x7 hours in bad conditions.  Our AdvantageLeading manufacuturer and Top supplier in Shenzhen, ChinaFactory Low Prices DirectProfessinal OEM/ODM and Personalized private customizeHigh Quality With Global Standards.We provide 12months Free Warranty for all our items (Not including damage made by the user).Quality: We have a strict quality control system.
