Safety Instruction
Read and follow these instructions when connecting and using your LCD monitor:
Operation:
1. Keep the monitor out of direct sunlight and away from stoves or any other heat
source.
2. Remove any object that could fall into ventilation holes or prevent proper cooling
of the monitor＇s electronics.
3. Do not block the ventilation holes on the cabinet.
4. When positioning the monitor, make sure the power plug and outlet are easily
accessible.
5. If turning off the monitor by detaching the power cable or DC power cord, wait
for seconds before attaching the power cable or DC power cord for normal
operation.
6. Do not subject the LCD monitor to severe vibration or high impact conditions
during operation.
7. Do not knock or drop the monitor during operation or transportation.
Maintenance:
8. To protect your display from possible damage, do not put excessive pressure on
the LCD panel. When moving your monitor, grasp the frame to lift; do not lift the
monitor by placing your hand or fingers on the LCD panel.
9. Unplug the monitor if you are not going to use it for an extensive period of time.
10. Unplug the monitor if you need to clean it with a slightly damp cloth. The screen
may be wiped with a dry cloth when the power is off. However, never use organic
solvent, such as, alcohol, or ammonia-based liquids to clean your monitor.
11. To avoid the risk of shock or permanent damage to the set, do not expose the
monitor to dust, rain, water, or excessive moisture environment.
12. If your monitor gets wet, wipe it with dry cloth as soon as possible.
13. If foreign substance or water gets in your monitor, please turn the power off
immediately and disconnect the power cord. Then, remove the foreign substance
or water, and send it to the maintenance center.
14. Do not store or use the LCD monitor in locations exposed to heat, direct sunlight
or extreme cold.
15. In order to maintain the best performance of your monitor and use it for a longer
lifetime, please use the monitor in a location that falls within the following
temperature and humidity ranges. Temperature: 5-35°C 41-95°F

Product Installation
1. Switch off the power on both your monitor and your computer. The Power Switch
is located in the right of the monitor.
2. Connect the power cord to the AC outlet, and connect the power to the monitor
through the AC/DC adapter.
3. VGA Signal-Plug one end of the 15-pin signal cable to the video signal connector
at the rear of the PC system and the other end to the monitor. Secure the
connectors with the screws on the cable connector at both ends.
4. (Optional) DVI Signal-Plug one end of the DVI signal cable to the video signal
connector at the rear of the PC system and the other end to the monitor. Secure
the connectors with the screws on the cable connector at both ends.
5. (Optional) HDMI Signal-Plug one end of the HDMI signal cable to the video
signal connector at the rear of the PC system and the other end to the monitor.
Secure the connectors with the screws on the cable connector at both ends.
6. (Optional) RS232 Connection- Plug one end of RS232 cable to com-port
connector on your PC system and the other end to the monitor. Secure the
connectors with the screws on the cable connector at both ends.

Note (1) Temperature and relative humidity range is shown in the figure below.
(a) 90 %RH Max. (Ta 40 ºC).
(b) Wet-bulb temperature should be 39 ºC Max. (Ta > 40 ºC).
(c) No condensation.
Note (2) The maximum operating temperature is based on the test condition that the surface temperature of
display area is less than or equal to 80 ºC with LCD module alone in a temperature controlled chamber.
Thermal management should be considered in your product design to prevent the surface temperature
of display area from being over 80 ºC. The range of operating temperature may degrade in case of
improper thermal management in your product design.
Note (3) 2 ms, half sine wave, 1 time for ± X, ± Y, ± Z.
Note (4) 10 ~ 300 Hz, 10 min, 1 time each X, Y, Z.
Note (5) At testing Vibration and Shock, the fixture in holding the module has to be hard and rigid enough so that
the module would not be twisted or bent by the fixture.

5.4 COLOR DATA INPUT ASSIGNMENT
The brightness of each primary color (red, green and blue) is based on the 8-bit gray scale data input for
the color. The higher the binary input, the brighter the color. The table below provides the assignment of
color versus data input.

Power ON/OFF Sequence
Note (1) The supply voltage of the external system for the assembly input should follow the definition of Vcc.
Note (2) Apply the lamp voltage within the LCD operation range. When the backlight turns on before the LCD
operation or the LCD turns off before the backlight turns off, the display may momentarily become
abnormal screen.
Note (3) In case of Vcc is in off level, please keep the level of input signals on the low or keep a high
impedance.
Note (4) T4 should be measured after the assembly has been fully discharged between power off and on period.
Note (5) Interface signal shall not be kept at high impedance when the power is on.

Note (2) Definition of Contrast Ratio (CR):
The contrast ratio can be calculated by the following expression.
Contrast Ratio (CR) = L255 / L0
L255: Luminance of gray level 255
L 0: Luminance of gray level 0
CR = CR (5), where CR (X) is corresponding to the Contrast Ratio of the point X at the figure in Note
(7).

Note (4) Definition of Luminance of White (LC):
Measure the luminance of gray level 255 at center point and 5 points
LC= L (5), where L (X) is corresponding to the luminance of the point X at the figure in Note (7).
Note (5) Definition of Cross Talk (CT):
CT = | YB– YA| / YA×100 (%)

Note (6) Measurement Setup:
The LCD assembly should be stabilized at given temperature for 30 minutes to avoid abrupt
temperature change during measuring. In order to stabilize the luminance, the measurement
should be executed after lighting Backlight for 30 minutes in a windless room.
