Working Principle of Monitor
Monitor works by using pixels to display the information. These are nothing but tiny dots that emit light. When the monitor receives electrical signals from any other source like for instance the video card that sends video signals, these signals are processed by the monitor and each pixel is illuminated using display technology. The color of each pixel is also determined after processing of signals. The internal circuit of the monitor control the pixel’s brightness and the user can see the images, videos and other outputs on the screen.
What is a Monitor?
During ancient times, before the introduction of monitors, devices like Abacus and mechanical calculators were used. After the development of the Analytical Engine by Charles Babbage, the theory of computers came into existence. Now the latest computers comprise basic components like Output Devices, Input Devices, RAM, ROM, CPU, Motherboard, Hard Disk Drives, Cooling Systems, etc. Output Devices are components of the computer. It converts electronic data to a readable format. This readable format can either be displayed to the user as end result or can be used by any other equipment. Some examples of Output Devices are monitors, printers, speakers, headphones, projectors, etc.
