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.

All broadcast stationstransmit digital signals
Many programs can bebroadcast on a singledigital channel
Uses digital signals to producecrisper, higher-quality outputon LCD and plasma televisions
HDTV (high-definition television)is the most advanced formof digital TV
Great for game playing, watching movies, and browsing the Internet

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.

Step 1.A small resistor heats the ink, causing the ink to boil and form a vapor bubble.
Step 2.The vapor bubble forces the ink through the nozzle.
Step 3.Ink drops onto the paper.
Step 4.As the vapor bubble collapses, fresh ink is drawn into the firing chamber.
