Amongo designs and manufactures a series of open frame touch screen monitor, covering the size from 6.5 inch to 80 inch. These monitors come with only a metal chassis to hold the components into place, also could be called a bare bone monitor system. The advantage of this is that it allows OEM and system integrator to drop-in an Open Frame Monitor into their design by mounting on flange-mount points or back-end VESA mount. It's with very simple structure design to save cost so as to meet clients' project budget. Amongo's open frame LCD touch monitor is widely used in ATM, VTM, ticket vending machines, self-service kiosk, vending machine, station information display and many other intelligent display applications.
Amongo's rack mount LCD monitors are designed to provide perfect image quality and up-to-date functions in a rugged rack-mountable enclosure, ensuring long term reliability and stability in industrial applications. The rack mount industrail touchscreen monitor features a robust industrial frame to meet the rigorous environments found in many industrial facilities. As a professional touchscreen monitor manufacturer, we can assure you that the side mounting brackets can be customized according to the requirement of customers to fit with their machines during installation, saving much more time and labor cost for end users.
How LCDs Work?
LCD(liquid crystal display) can be seen everywhere in our life. It can be said that our life today is inseparable from these advanced technologies. So we know how the content of LCD screen is presented to us, below we will give you a brief introduction to the working principle of LCD LCD screen.
1, LCD structure: LCD is short for liquid crystal display screen. The LCD screen mainly includes: back light plate, up and down polarized light, liquid crystal, glass substrate, etc.
2, color rendering principle: because the RGB three colors are printed on the color filter color piece, such as back light of light across the screen, the light through a transparent TFT thin film transistor substrate first, through the liquid crystal molecules, and then through the CF color filter, liquid crystal molecules penetrate rate under different from various colors, the influence of color piece will make different red, green, blue, light and shade In order to blend together to show the desired color.
3, liquid crystal: liquid crystal is a kind of special substance. It is a crystal anisotropic also have liquid’s fluidity at the same time, most of the liquid crystal molecules are rod-shaped molecules, originally is the direction of different LCD, under the action of different voltage presents different optical properties, as if is the magnetic field in the metal, under the influence of external electric field, the liquid crystal molecules also received certain effect. So we just have to control the arrangement of the liquid crystal molecules so that we can control the direction of light through the liquid crystal. As shown in the picture:
4, polarizing light: the top and bottom of the LCD screen have a polarizing film, they are perpendicular to each other, under normal circumstances is not through the light, but in the middle of the 2 pieces of polarizing film added liquid crystal everything is different. The liquid crystal molecules in the drawing below are arranged in a spiral line to create a rotating light that passes through a second layer of polarizer and appears at the front of the screen.
