
Digital Imaging and Communications in Medicine (DICOM)
DICOM was jointly developed by American College of Radiology (ACR) and National Electrical
Manufacturers Association (NEMA).
DICOM-compatible device connections can transmit medical images and data. DICOM Part 14 specifies the
standard display functions of medical gray scale images.

Digital Visual Interface (DVI)
DVI is a digital video interface standard for transmitting uncompressed digital video data to display devices.
DVI is a type of basic electrical connection based on the electronic protocol called Transition Minimized
Differential Signaling (TMDS).
DVI interfaces are divided into the DVI-D interface (which only receives digital signals) and the DVI-I interface
(which receives analog and digital signals).

DisplayPort (DP)
DP is a high-definition digital presentation interface standard for connecting computers and displays. DP
interfaces support HDCP digital content protection protocols and can transmit HD audios and videos through a
single cable.

Gamma
The relationship between the LCD monitor's brightness and its input voltage is non-linear. A smaller gamma
value generates an image with lower contrast, whereas a greater gamma value generates an image with higher
contrast.

In-Plane Switching (IPS)
IPS is an LCD panel technology introduced by Hitachi in 2001. Up to now, five generations of technologies (IPS,
S-IPS, AS-IPS, IPS-PRO, and IPS-NEO) have been developed for IPS.

Lux
Lux is a unit of illumination, in which a luminous flux of 1 lux equals 1 lumen (LM) uniformly distributed over
2
an area of 1 m .

Number of pixels
Resolution indicates the accuracy of an image displayed on the screen, measured by the number of displayed
pixels. For example, a monitor with a resolution of 2048x1536 consists of 1536 vertical pixels and 2048
horizontal pixels.

Pixel pitch
Pixel pitch indicates the distance between two adjacent pixels of the same color (red, green, or blue) on the
screen.

Relative humidity (RH)
RH is the percentage of the actual vapor density in unit volume air compared with the saturated vapor density at
the same temperature.

Video Electronics Standards Association (VESA)
VESA is an international organization that develops video equipment standards for computers and small
workstations, and has been committed to developing and promoting display-related standards.
