1.3.5 Controller Requirements:
1.3.5.1 General Requirements:
The monitor shall include a controller which is capable of converting the analog RGB signal or DVI
digital signal to the panel. The controller will include a PLL, A/D converters, TMDS receiver and other
circuitry necessary to perform its function. The PLL shall be stable enough to ensure a stable image.
1.3.5.2 Video Stretching:
The monitor shall have the function to “stretch” the video signal, so that an input signal from the
computer in any resolution smaller than 1920x1080 is automatically expanded to fill the entire
screen.
1.3.5.3 Panel Timing and Interface:
The controller supplied with the monitor shall control all panel timing. This controller shall adequately
insulate the monitor from the computer, so that no possible combination of input signals from the
computer shall cause damage to the flat panel or any other component of the monitor.
1.3.6 Power Adaptor Requirements:
The AC to DC power adaptor for this monitor shall be a DC power supply. This power adaptor shall have an IEC
receptacle for mains power input and provide sufficient power for backlight assembly
,
interface board and panel. And it
should meet all requirements specified in following Table.
AC TO DC Converter
Requirement
Input Voltag
e
Ra
nge
The opera ting range shall be from 90 to 264 VAC sinusoidal for all
models
specified.
Input
Frequency
Range
Input power frequency range shall be
f
rom 47 to
63Hz.
Power
Consumption
Power consumption for the monitor shall be less than 30 W over the
specified
voltage and frequency ranges.
In
power off mode the power consumption will be less than 0.6W
(at
11
0VAC).
Lin e
Fuse
The AC input shall be fused and become electrically open as a result on
an
unsafe current level. The fuse
may
not user
replaceable.
Initial
Cold
Start
The power adaptor shall start and function properly when under full load,
with
worst case conditions of in
put
voltage, input frequency, operating
tem
perature, and cold backlight LE D
.
Inrush
Current
The inrush current must be limited to when operated at 120VAC,
a
nd when operated at . In
rush current is
measured at an
ambient
temperature of 25
°
C, with the unit temperature stabilized in the power
off.
Hot
Start
Cycle
The power adaptor shall not be damaged when power ON for one second
and
OFF for one second for
seven
consecu
tive times after opera ting for one hour at full load, 25
°
C, and nom
inal
input line
voltage.
Under
Voltage
The power adaptor shall contain protection circuitry such that the application
of
an
input voltage below
the
minimum specified in this table shall no t cause damage to the power
adaptor
unit
nor cause failure of the inp
ut.
Line Tran
sient
The power adaptor shall operate within EN 61000-4-4 (+/-1KV) and EN
61000-4-5(+/-2KV).
The power adaptor shall operate and comply with CE
mark.
1.3.7 Display Communications Channel:
The monitor shall provide a display communications channel that conforms to VESA DDC2B
hardware requirements. This configuration shall contain the 128-byte EDID file as specified by
VESA E-EDID Standard. Once the EDID is programmed the write protection function will enabled.
So the EEPROM data cannot be overwritten.
