Video Input Signal Ranges

1.3.2.1 Video Signal Amplitudes

The three video inputs consis

t of

Red ,Green , and

signals, each with its own coaxial cable terminated at the

monitor. These video signals are analog levels, where 0

V corresponds to black , and 700 mV is the maximum

1.3.2.3 Synchronization ( Sync ) Signals

The Horizontal Sync (HS) TTL signal is used to initiate

the display of a horizontal line. HS may be either active

high or active low, depending upon the timing .The

Vertical Sync (VS) TTL signal is used to initiate the

display of a new frame .VS may be either active high or

active low, depending on the timing

1.3.2.4 Sync Signal Levels

The monitor must accept sync signals from both 3.3 and

5 volt TTL logic families.The inputs shall sense a logic 0

when the input is 0.8 volt or less and shall sense a logic

1 when the input is 2.0 volts or greater. In addition to

these level requirements, there shall also be a minimum

of 0.3 volt hysteresis provided for noise immunity

(typically by using a Schmitt Trigger input ).That is , the

input level at which the monitor actually detects a logic 0

shall be at least 0.3 volt lower than the level at which it

actually detects a logic 1.If the monitor sync processing

circuits are designed around the 3.3 volt logic family

,then the sync inputs must be 5 volt tolerant .

and within +/-1Hz for vertical.

1.3.4.4 User Display Modes

In addition to the factory pre-set video modes,

provisions shall be made to store up to 9 user

modes. If the current mode is a user mode, the

monitor shall select its previously stored settings.

If the user alters a setting, the new setting will be

stored in the same user mode. The user modes

are not affected by the pre-set command. If the

the new format is automatically performed during

user adjustment of the display (if required).(

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. The

LCD panel interface shall support the TFT

1.3.6 DC - AC Inverter Requirements

The DC-AC inverter is on the power board. The

frequencies used by the DC-AC inverter used to power the

backlight shall be chosen so as to prevent any noticeable

effects on the flat panel (such as a rolling effect).

1.3.7 Power Supply Requirements

The AC to DC converter power supply for the monitor shall

be an external AC to DC converter ”brick” This brick shall

1.3.5 Controller Requirements

1.3.5.1 General Requirements

The monitor shall include a controller capable of

converting the analog RGB signal from a standard

SXGA resolution video controller in the CPU to a

signal which can be displayed on the panel. The

controller will include a PLL, A/D converters, LVDS

transmitter and other circuitry necessary to perform

its functio

n. The

PLL shall be

stabl

e enough to

ensure that a static image from the CPU is placed

in the

same phys

ical locati

on on

the flat panel in

each frame.

1.3.4.3 Mode Recognition Pull-in

The monitor shall recognize preset modes within a

range of +/-1KHz whichever is less for horizontal ;

and within +/-1Hz for vertical.

1.3.4.4 User Display Modes

In addition to the factory pre-set video modes,

provisions shall be made to store up to 9 user

modes. If the current mode is a user mode, the

monitor shall select its previously stored settings.

If the user alters a setting, the new setting will be

stored in the same user mode. The user modes

are not affected by the pre-set command. If the

input signal requires a new user mode, storage of

the new format is automatically performed during

user adjustment of the display (if required).(

Please see Note.(4) )

Preset timing Chart

1.3.5.2 Video Stretching

The monitor shall contain provisions to “stretch” the

video signal, so that an input signal from the

computer in any resolution smaller than 1366 x

768 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. The

LCD panel interface shall support the TFT

standard.

1.3.6 DC - AC Inverter Requirements

The DC-AC inverter is on the power board. The

frequencies used by the DC-AC inverter used to power the

backlight shall be chosen so as to prevent any noticeable

effects on the flat panel (such as a rolling effect).

1.3.7 Power Supply Requirements

The AC to DC converter power supply for the monitor shall

be an external AC to DC converter ”brick” This brick shall

have an IEC receptacle for main power input and a pin - in

---socket for DC power out. The brick shall provide

sufficient power for both the monitor and the backlight

assembly, and shall meet requirements specified in Table

1. Product Specification (continued)

second and OFF for one second for

seven consecutive after

operating for one hour at full

load, 25

voltage.

Under Voltage

The power supply shall

contain protectio

n circuitry such that the

application of an input voltage below the minimum specified in this

table shall not cause damage to the

power supply unit nor cause

failure of the input.

The power

supply shall

operate within IEC

801

-4 (± 1KV) and IEC

801-5 (± 2KV) for the domestic U.S. version. The UPS power

supply shall operate and comply with CE mark.

1.3.8 Display Communications Channel

The monitor assembly shall provide a display

communications channel that conforms to VESA

DDC2Bi hardware requirements. This configuration

shall contain the 128-byte EDID file as specified by

VESA EDID standard.The monitor should not write to

the EDID file for

the first two minutes of operation

following power-up UNLESS some action taken by the

user or the host CPU forces the write (for instance,

requesting the serial number via the OSD).

Furthermore, it is recommended that CMOS switches

be incorporated to isolate the DDC IC from outside

connections while the EDID Fault Management is

being updated. This is to prevent corruption of the data

by attempt

s to

read the data

while it is

being chang

ed.

1.3.9 Firmware Update Function (same ISP function)

The update firmware need through from the D-Sub

connector, use DDC I2C bus to do update firmware.

the display devic

e shall be

WXGA 1366X768 resolution, 19 inch-wide TFT-LCD.

The lamps shall extend a sufficient amount from

the edge of

the light guide that

sputt

ering over the

life of

the lamps shall not cause degradat

ion of

the

luminance uniformity (such as non-illuminated

bands along the edges of the display).

1.4.4.2 Lamps Startup Time

The backlight lamps shall start about 2 sec of the

time the monitor power switch is pressed or the
