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

Optical Equipment: BM-7, DT-101, or equivalent

Note 1: Definition of viewing angle

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.

IDK-2121W User Manual 4

Note 2: 9 points position

Note 3: The luminance uniformity of 9 points is defined by dividing the maximum

luminance values by the minimum test point luminance

Note 4: Measurement method

The LCD module 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 the backlight has been on for 30 minutes in a

stable, windless and dark room. Optical Equipment: DT-100, or equivalent

Note 5: Definition of response time:

The output signals of the photo detector are measured when the input signals are

changed from “Full Black” to “Full White” (rising time), and from “Full White” to “Full

Black ”(falling time), respectively. The response time is the interval between the 10%

and 90% of amplitudes. Please refer to the figure as below.
