1

Tiny liquid crystal molecules

Sub-pixels

2

A tiny distinct group of three sub-pixels - one red, one green, one blue

Pixel

3

Process to create an image by charging each area at the same time

Static Charging

4

Process to create color by varying the amount of voltage on the wires making different levels of red, green, and blue

Passive Matrix

5

Type of liquid crystal display (LCD) that replaced the passive matrix technology used in most portable computer displays

Thin Film Transister (TFT)/Active Matrix

6

Creates the image

LCD Panel

7

Illuminates the image so you can see it

Backlights

8

Sends power to the backlights that need AC electricity

Inverters

9

LCD panel type that is the fastest but only offers adequate color

Twisted Nematic (TN) Panels

10

LCD panel type that displays beautiful color

In-Plane Switching (IPS) Panels

11

LCD panel type that falls somewhere in between TN and IPS panels in responsiveness and color accuracy

Vertical Alignment (VA) Panels

12

Typical implementation for backlights where the LCD has two backlights: one at the top and one at the bottom

Edge LED Backlighting

13

Puts a bank of LEDs behind the panel, providing better uniformity of image. More expensive and uses more power than edge LED backlighting

Direct LED Backlighting

14

Technology used in early LCDs that were popular for its low power use, even brightness, and long life

Cold Cathode Fluorescent Lamp (CCFL)

15

Describes the number of pixels on a display

Resolution

16

The resolution that an LCD monitor is designed to run. Higher than native cannot be run, lower than native will severely degrade the image quality

Native resolution

17

Edge-blurring technology that softens the jagged corners of the pixels when running at lower than native resolution

Interpolation

18

640x480 resolution

VGA

19

1366x768 resolution

WXGA

20

1920x1080 resolution

1080p/FHD (full high definition)

21

The number of pixels arranged on the screen

Aspect Ratio

22

Aspect ratio for a typical widescreen monitor running at 1920x1080

16:9

23

Aspect ratio for a video workstation monitor running at 3440x1440

21:9

24

The combination of the resolution and physical size of a display. Higher number means that a smaller, hi-res monitor will look substantially better than a much larger monitor running at the same resolution

Pixels Per Inch (PPI)

25

The strength of an LCD monitor’s backlights, measuring in nits. Average LCD panels are around 300 nits

Brightness

26

Screen fade out when looking at a screen from a certain angle. IPS panels have 2.5 times better angle than TN panels

Viewing Angle

27

The amount of time it takes for all of the sub-pixels on the panel to change from one state to another. Measured in milliseconds (ms) with lower being better

Response Rate

28

Response rate measurement for how long it takes the pixels to go from pure black to pure white

Black-to-white (BtW)

29

Response rate measurement for how long it takes the pixels to go from one gray state to another. Always faster than BtW

Gray-to-gray (GtG)

30

How often a screen can change or update completely. Measured in hertz

Refresh Rate
