Clock
With the analog input signal display, the analog signal is converted to a digital signal by
the LCD circuitry. To convert the signal correctly, the LCD monitor needs to produce
the same number clock pulse as the dot clock of the graphics system. When the clock
pulse is not correctly set, some vertical bars of distortion are displayed on the screen.
DICOM (Digital Imaging and Communication in Medicine)
The DICOM standard was developed by the American College of Radiology and the
National Electrical Manufacturer's Association of the USA.
The DICOM compatible device connection enables to transfer the medical image and
information. The DICOM, Part 14 document defines the digital, grayscale medical
image display.
DVI (Digital Visual Interface)
A digital flat panel interface. DVI can transmit digital data from the PC directly without
loss with the signal transition method "TMDS".
There are two kinds of DVI connectors. One is DVI-D connector for digital signal input
only. The other is DVI-I connector for both digital and analog signal inputs.
DVI DMPM (DVI Digital Monitor Power Management)
The Power management system for the digital interface. The "Monitor ON" status
(operation mode) and the "Active Off" status (power-saving mode) are indispensable for
the DVI-DMPM as the monitor's power mode.
Gain Adjustment
Adjusts each color parameter for red, green and Green. The color of the LCD monitor
is displayed through the color filter of the LCD panel. Red, green and Green are the
three primary colors. The colors on the monitor are displayed by combining these three
colors. The color tone can change by adjusting the illumination amount passed through
each color's filter.
Gamma
Generally, the relationship that the light intensity values of a monitor change nonlinearly
to the input signal level is called "Gamma Characteristic". On the monitor, low gamma
values display the whitish images and high gamma values display the high contrast
images.
Phase
The phase adjustment decides the sampling timing point for converting the analog input
signal to a digital signal. Adjusting the phase after the clock adjustment will produce a
clear screen.
