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.

1.1 General Description
IDK-2121W series is a Color Active Matrix Liquid Crystal Display composed of a TFT-
LCD panel, a driver circuit, and backlight system. The screen format is intended to
support the FHD (1920(H) x 1080(V)) screen and 16.7M colors (RGB 8-bits data). All
input signals are dual LVDS interface. Driver board for the backlight is included.

1.3 Optical Characteristics
Note 1: Measurement Method
Before measuring, the LCD module should be turn on 30 minutes at room tempera-
ture. In order to stabilize the luminance, the measurement should be executed after
lighting Backlight for 30 minutes in a stable, windless and dark room.

Note 2: Definition of viewing angle measured by ELDIM (EZContrast 88)
Viewing angle is the measurement of contrast ratio at the screen center, over a
180°horizontal and 180°vertical range (off-normal viewing angles). The 180° viewing
angle range is broken down as below: 90° (θ)? horizontal left and right, and 90° (Φ)
vertical high (up) and low (down). The measurement direction is typically perpendicu-
lar to the display surface with the screen rotated to its center to develop the desired
measurement viewing angle.
Note 3: Contrast ratio is measured by TOPCON SR-3
Note 4: Definition of Response time measured by Westar TRD-100A
The output signals of photo detector are measured when the input signals are
changed from “Full Black” to “Full White” (rising time, TrR), and from “Full White” to
“Full Black” (falling time, TrF), respectively. The response time is interval between the
10% and 90% (1 frame at 60Hz) of amplitudes.
TrR + TrF = 16msec (typ.)
Note 5: Color chromaticity and coordinates (CIE) is measured by TOPCON SR-3
Note 6: Central luminance is measured by TOPCON SR-3
