A Message to the Customer

Advantech Customer Services

Each and every Advantech product is built to the most exacting specifications to ensure reliable performance in the harsh and demanding conditions typical of industrial environments. Whether your new Advantech equipment is destined for the laboratory or the factory floor, you can be assured that your product will provide the reliability and ease of operation for which the name Advantech has come to be known.

Your satisfaction is our primary concern. Here is a guide to Advantech's customer services. To ensure you get the full benefit of our services, please follow the instructions below carefully.

Technical Support

We want you to get the maximum performance from your products. So if you run into technical difficulties, we are here to help. For the most frequently asked questions, you can easily find answers in your product documentation. These answers are normally a lot more detailed than the ones we can give over the phone.

So please consult this manual first. If you still cannot find the answer, gather all the information or questions that apply to your problem, and with the product close at hand, call your dealer. Our dealers are well trained and ready to give you the support you need to get the most from your Advantech products. In fact, most problems reported are minor and are able to be easily solved over the phone.

In addition, free technical support is available from Advantech engineers every business day. We are always ready to give advice on application requirements or specific information on the installation and operation of any of our products.

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 purchase.

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 defective, 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.

    C["Power Supply"] --> D["GND"]
    D --> B
    B --> E["LED Backlight Unit"]

Note 2: At 20k Hz PWM control frequency, duty ratio range is restricted from 20% to 100%.

Note 3: The lifetime of LED is estimated data and defined as the time when it continues to operate under the conditions at Ta = 25 ±2°C and Duty 100% until the brightness becomes ≤ 50% of its original value. Operating LED under high temperature environment will reduce life time and lead to color shift.

Power sequence and control signal timing are shown in the following figure.

Note! While system is turned ON or OFF, the power sequences must follow as below descriptions.

Turn ON sequence: Vi(+12V) EN Dimming

Turn OFF sequence: Dimming → EN → Vi(+12V)

Note 4: The lifetime of LED is estimated data and defined as the time when it continues to operate under the conditions at Ta = 25 ±2°C and Duty 100% until the brightness becomes ≤ 50% of its original value. Operating LED under high temperature environment will reduce life time and lead to color shift.

Note 1: Please avoid a floating state of interface signal at an invalid period.

Note 2: When the interface signal is invalid, be sure to pull down the power supply of LCD VCC to 0 V.

Note 3: The backlight converter power must be turned on after the power supply for the logic and the interface signal to be valid. The backlight converter power must be turned off before the power supply for the logic and the interface signal to be invalid.

Note1 Definition of viewing angle

Viewing angle is the measurement of contrast ratio ≥10 , 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: 90^() horizontal left and right, and 90^() vertical high (up) and low (down). The measurement direction is typically perpendicular to the display surface with the screen rotated to its center to develop the desired measurement viewing angle.

Normal θx = θy = 0° θy- θy+ θx- θx- θx+ 12 o'clock direction θy+ = 90° 6 o'clock θy- = 90° x+ θx+ = 90°

Note2 9 points position

Note3 9-point luminance uniformity is defined by dividing the maximum luminance values by the minimum test point luminance

$$ \delta_ {w 9} = \frac {\text { Minimum Brightness of nine points }}{\text { Maximum g Btness of nine points }} $$

Note4 Measurement method

The LCD module should be stabilized at given temperature for 20 minutes to avoid abrupt temperature change during measuring. In order to stabilize the luminance, the measurement should be executed after lighting Backlight for 20 minutes in a windless room.

Note5 Definition of Response Time (T_R, T_F) :

Note 6 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

L0: Luminance of gray level 0

$$ \mathrm{CR} = \mathrm{CR} (5) $$

CR (X) is corresponding to the Contrast Ratio of the point X at Figure in Note 2.

Handling Precautions

B.1 Handling Precautions

The optical characteristics are measured under stable conditions at 25^ C (Room Temperature)

1. Since the front polarizer is easily damaged, be very careful not to scratch it.
2. Be sure to turn off the power supply when inserting or disconnecting from the input connector.

3. Wipe off water drops immediately. Long contact with water may cause discoloration or spots.

4. When the panel surface is soiled, wipe it with absorbent cotton or another soft cloth.

5. Since the panel is made of glass, it may break or crack if dropped or bumped on a hard surface.

6. Since the CMOS LSI is used in this module, be careful of static electricity and ensure you ground yourself first before handling.

7. Do not open or modify the Module Assembly.

8. Do not press the reflector sheet at the back of the module in any direction.

9. In case a Module has to be put back into the packing container slot after it has been taken, please touch the far ends of the LED light bar reflector edge softly, otherwise the TFT Module may get damaged.

10. At the insertion or removal of the signal interface connector, be sure not to rotate nor tilt the Interface Connector on the TFT Module.

11. After installation of the TFT Module into an enclosure, do not twist nor bend the TFT Module even momentary. During integration of the enclosure, it should be taken into consideration that no bending/twisting forces are applied to the TFT Module from outside. Otherwise the TFT Module may get damaged.

12. A small amount of materials having no flammability grade are used in the LCD module. The LCD module should be supplied by power compliant with the requirements of Limited Power Source (IEC60950 or UL1950), or be applied exempt thereof.
