screen, showing how triads of red, green, and blue appear.
You also may encounter a few specialized monitor types. For example,
some e-book readers have a special type of screen called electronic paper
(
e-paper
). This type of screen retains its image but is unpowered except
when the display changes, so it uses much less power than a device with
an LCD screen. A
digital
or smart whiteboard is a large writing board in
a conference room or other meeting area that is connected to a computer,
so that whatever is written on the board is also saved on the computer.
Digital tools and buttons also appear on the screen for interacting with
the data collected, as shown in Figure 3.19.
