Step 5.Electron guns fire the three color signals to the front of the CRT.
Step 1.The processor sends digital video data to the video card.
Step 3.The analog signal is sent through a cable to the CRT monitor.
Step 4.The CRT monitor separates the analog signal into red, green, and blue signals.
Step 6.An image is displayed on the screen when the electrons hit phosphor dots on the back of the screen.
Step 2.The video card’s digital-to-analog converter (DAC) converts the digital video data to an analog signal.

Polarizing glass filter
Fluorescent tube panel
Step 2.As light passes through liquid crystal, electrical charge causes some of the cells to twist, making light waves bend as they pass through color filter.
Step 1.Panel of fluorescent tubes emits light waves through polarizing glass filter, which guides light toward layer of liquid crystal cells.
Step 3.When light reaches second polarizing glass filter, light is allowed to pass through any cells that line up at the first polarizing glass filter. Absence and presence of colored light cause image to display on the screen.

Step 2.Rotating mirror deflects low-powered laser beam across surface of drum.
Step 1.After user sends an instruction to print a document, drum rotates as gears and rollers feed sheet of paper into printer.
Step 5.Set of rollers uses heat and pressure to permanently fuse toner to paper.
Step 4.As drum continues to rotate and press against paper, toner transfers from drum to paper.
Step 3.Laser beam creates a charge that causes toner to stick to drum.
