Product Warranty (2 years)
Advantech warrants to you, the original purchaser, that each of its products will be
free from defects in materials and workmanship for two years from the date of pur-
chase.
This warranty does not apply to any products which have been repaired or altered by
persons other than repair personnel authorized by Advantech, or which have been
subject to misuse, abuse, accident or improper installation. Advantech assumes no
liability under the terms of this warranty as a consequence of such events.
Because of Advantech’s high quality-control standards and rigorous testing, most of
our customers never need to use our repair service. If an Advantech product is defec-
tive, it will be repaired or replaced at no charge during the warranty period. For out-
of-warranty repairs, you will be billed according to the cost of replacement materials,
service time and freight. Please consult your dealer for more details.
If you think you have a defective product, follow these steps:
1. Collect all the information about the problem encountered. (For example, CPU
speed, Advantech products used, other hardware and software used, etc.) Note
anything abnormal and list any onscreen messages you get when the problem
occurs.
2. Call your dealer and describe the problem. Please have your manual, product,
and any helpful information readily available.
3. If your product is diagnosed as defective, obtain an RMA (return merchandise
authorization) number from your dealer. This allows us to process your return
more quickly.
4. Carefully pack the defective product, a fully-completed Repair and Replacement
Order Card and a photocopy proof of purchase date (such as your sales receipt)
in a shippable container. A product returned without proof of the purchase date
is not eligible for warranty service.
5. Write the RMA number visibly on the outside of the package and ship it prepaid
to your dealer.

2.1 TFT LCD Module
Requires two power inputs, one is employed to power the LCD electronics and to
drive the TFT array and liquid crystal. The second power input is for the LED/Back-
light, typically generated by a LED Driver. The LED Driver is an external unit to the
LCDs.

quency)=MAX condition)

Rush current IRUSH -- 3A 4
Note! 1. Permissive power ripple should be measured under VLCD =5.0V,
25°C, fV (frame frequency)=MAX condition and At that time, we
recommend the bandwidth configuration of oscilloscope is to be
under 20Mhz. See the next page.
2. The specified current and power consumption are under the
VLCD=5.0V, 25± 2°C,fV=60Hz condition whereas Typical Power
Pattern [Mosaic] shown in the [ Figure 3 ] is displayed.
3. The current is specified at the maximum current pattern.
4. Maximum Condition of Inrush current:
The duration of rush current is about 5ms and rising time of power
Input is 500us 20%.(min.).
5. VLCD level must be measured at two points on LCM PCB -
between VLCD (test point) and LCM Ground.
The measured results need to meet the Power supply input voltage
spec.
(Test condition : maximum power pattern, 25± 2°C, fV=60Hz)

Note! 1. All GND (ground) pins should be connected together and to Vss
which should also be connected to the LCD’s metal frame.
2. All VLCD (power input) pins should be connected together.
3. Input Level of LVDS signal is based on the IEA 664 Standard.
4. Always make sure LVDS signal and clock inputs should be 4 chan-
nels and synchronized.
5. Basically Panels cannot support “Interlaced Scan Method” and
ITLC is Interlace Image Sticking Reduction Mode selection pin.
(L: Normal Mode, H: Interlace Image Sticking Reduction Mode)
If you don’t use this pin, it should be connected to GND.
