19
Q

LCD (CCFL)

A

Liquid Crystal Display (cold cathode fluorescent lamp)

Liquid crystal cells to polarize light passing through the display to create the image.

20
Q

LED (LCD-LED)

A

Light Emitting Diode

Use a cold cathode fluorescent lamp (CCFL) as the lighting source

21
Q

Plasma

A

Use small cells that contain electrically charged ionized gases; effectively, these are fluorescent lamps. Mostly used for Television sets.

22
Q

Data Projectors

A

Used in place of a primary display or can be used as a clone of the primary display to permit computer information and graphics to be displayed on a projection screen or a wall.

23
Q

OLED

A

Organic Light Emitting Diodes

Use organic semiconductor material usually in the form of polymers.

24
Q

TN

A

Twisted Nematic

LCD displays that provides short response time and high brightness, making them highly suitable for gaming.

25
Q

IPS

A

In Plane Switching
LCD displays that has a slower response time and uses as much as 50% more power than a TN display. However, an IPS display has a wider viewing angle without distorted colors or loss of contrast.

26
Q

Resolution

A

Described as the amount of pixels on a screen, measured horizontally by vertically.

27
Q

16:10
1920x1200
28
Q

Refresh Rate

A

Refers to how quickly the monitor redraws the screen and is measured in hertz(Hz), or times per second.
Default is usually 60Hz

29
Q

Frame Rate

A

Refers to the frames per second(fps) speed of 3D rendering during games.
