Detailed explanation-1: -Thin film transistor monitor. Screen made up of thousands of tiny pixels, which are made up of transistors controlled by a microprocessor. Liquid crystal display monitor. It uses liquid crystal diodes.
Detailed explanation-2: -TFTs are Active-Matrix LCDs that have tiny switching transistors and capacitors. These tiny transistors control each pixel on the display and require very little energy to actively change the orientation of the liquid crystal in the display.
Detailed explanation-3: -Each pixel is made up of a red, green and blue subpixel that lights up at different intensities to create different colors. The specific color information that a pixel describes is some blend of three components of the color spectrum–RGB.
Detailed explanation-4: -Each pixel in an active-matrix LCD is controlled by a thin-film transistor (TFT), a very simple switch connected to the pixel’s row and column wires. When the switch is triggered, it uses current stored in a capacitor to maintain a steady charge on the pixel during an entire screen-refresh cycle.
