75Ωto Ground

1.3.2.1 Video Signal Amplitudes The three video inputs consist of Red ,Green , and Blue 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 signal amplitude for the respective color, when each signal is terminated by a nominal 75.0 ohms .For a given monitor luminance levels are measured using this defined video amplitud driving a monitor meeting the termination requirements .The signal amplitude is not to be readjusted to compensate for variations in termination impedance.

1.3.2.2 Video Signal Termination Impedance This analog video signal termination shall be 75 1% which shall be resistive with a negligible reactive

component

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 .

1.3.2.5 Sync Signal Loading

TTL input loading shall be equivalent to one TTL input load. When logic 0 is asserted by a sync input , the maximum current source from any single monitor sync input to the driver is 1.6 mA .When logic 1 is asserted , the maximum current source from the driver to any single monitor sync input is 400 uA .

1.3.2.6 Abnormal Signal Immunity The monitor shall not be damaged by improper

sync timing , pulse duration , or absence of sync , or abnormal input signal amplitude ( video and/ or sync too large or too small) , or any other anomalous behavior of a graphics card video generator when changing modes , or when any combination of input signals is removed or replaced . Additionally , under these conditions , the monitor shall not cause damage to the driving source

1.3.3 User Controls and Indicators

1.3.3.1 Power On / Off Switch The monitor shall have a power control switch visible and accessible on the front of the monitor . The switch shall be marked with icons per IEC 417 , # 5007 and # 5009.The switch shall interrupt the DC supply to the monitor

1.3.3.2 Power Indicator LED The monitor shall make use of an LED type

indicator located on the front of the monitor .

1.3.4 Monitor Modes and Timing Capability

1.3.4.1 Format and Timing The monitor shall synchronize with any vertical frequency from 56 to 75 Hz , and with any horizontal frequency from 31 to 83KHz. If the input frequency is out of the above – specified range, the monitor shall display a warning screen indicating that the input frequency is out of range. Under no circumstances shall any combination of input signals cause any damage to the monitor .

1.3.4.2 Factory Assigned Display Modes There are 21 factory pre-set frequency video modes. These modes have a factory pre-set for all characteristics affecting front-of-screen performance. When the system is poweredon,previously stored screen parameters for a predefined mode will be recalled if the operating mode is one of those stored in memory. If the operating mode is not one of those stored in memory, the monitor CPU will select the PRESET timing for a mode that is the next lowest in horizontal scanning frequency to the mode being currently used. The screen parameters may be adjusted by the use of the front bezel controls and then may be saved as a user defined mode. The monitor shall include all the preset video timings shown in the following page.(Please see Note.(3) )

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. Product Specification (continued)

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 attempts to read the data while it is being changed.

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.

1.4 PANEL ELECTRICAL

1.4.2 Panel Timings The controller included with the monitor shall translate

all video timings from the CPU that meet the timing requirements listed in Panel specification into timings appropriate for the panel. Under no circumstances may the controller supply the panel with timings that may result in damage. The controller shall insulate the panel from the CPU , so that the panel shall always be driven per it's own specification regardless of the timings being sent from the CPU.

1.4.3 Polarizer Hardness The outer face of the front polarizer panel shall be

covered with a coating witha#3hardness value

1.4.4 Backlight Requirements

1.4.4.1 General Requirements

The lamps shall extend a sufficient amount from the edge of the light guide that sputtering over the life of the lamps shall not cause degradation 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 monitor is restarted from a power - down mode .The starting time shall stay about 2 sec. for the minimum expected life of the lamps.
