Technical Process of an Lcd Computer Monitor
How it’s made:
Computer LCD Monitors
Today, computer monitors are a vital part of a person’s life. It is a part of your basic desktop bundle, and without it, you wouldn’t be able to use your computer, unless, of course, you use your T.V as a monitor. Computer monitors are tremendously made as liquid crystal displays. They are used because they are thinner and lighter and use much less power than cathode ray tube monitors. LCD computer monitors are made in a specific and special type of way.
Computer monitors contain raw and treated materials like metal semiconductors, phosphorous, lead and mercury. Depending on the type of computer screen, different types and amounts of such materials will be used. In general, the type of display technology determines the nature of these materials due to their electrical makeup. Computer screens that contain hazardous materials such as mercury and lead are harmful to the environment and should be recycled properly.
Liquid crystal display technology works by blocking light. Specifically, an LCD is made of two pieces of polarized glass that comprise a liquid crystal material between them. A backlight creates light that passes through the first polarized glass. Simultaneously, electrical currents cause the liquid crystal molecules to align, allowing, varying levels of light to pass through to the second polarizing glass and create the colors and images that you see.
Most LCD monitors use active matrix technology. A thin film transistor arranges tiny transistors and capacitors in a matrix on the glass of the display. To address a particular pixel, the proper row is switched on, and then a charge is sent down through the correct column. Since all of the other rows that the column overlaps are turned off, only the capacitor at the selected pixel receives a charge. The capacitor is able to hold the charge until the next refresh cycle. The other type of LCD technology is passive matrix. This type of LCD monitor uses a network of
