Chapter 7 Glossary
Gamma
Generally, the monitor brightness varies nonlinearly with the input signal level, which is called “Gamma Characteristic”. A small gamma value produces a
low-contrast image, while a large gamma value produces a highcontrast image.
HDCP (High-bandwidth Digital Content Protection)
Digital signal coding system developed to copy-protect the digital contents, such as video, music, etc.
This helps to transmit the digital contents safely by coding the digital contents sent via the DVI or HDMI connector on the output side and decoding them
on the input side.
Any digital contents cannot be reproduced if both of the equipments on the output and input sides are not applicable to HDCP system.
HDMI (High-Definition Multimedia Interface)
HDMI is a digital interface standard, developed for consumer electrical appliance or AV device. This standard is issued on the basis of the DVI standard
which is one of an interface specification for the connection between a PC and a monitor. The projected image, sound and control signal without
compressed enable to be transmitted with one cable.
Overdrive
This technology enhances response speed by increasing the potential difference at the time of motion of liquid-crystal pixels, and it is used for liquid-
crystal TV sets and others in general. It provides clear-cut three-dimensional display with little afterimage, by improving response speed of the intermediate
graduation range that frequently appears in moving images.
Phase
Phase means the sampling timing to convert the analog input signal to a digital signal. Phase adjustment is made to adjust the timing. It is recommended
that phase adjustment be made after the clock is adjusted correctly.
Range Adjustment
Range adjustment controls the signal output levels to display every color gradation. It is recommended that range adjustment be made before color
adjustment.
