PRACTICAL GUIDANCE TO OUR CUSTOMERS
Flexible Printed Circuit (FPC) Damage
Good Display ePaper Displays include a Flexible Printed Circuit ("Flex"). These are actual electronic circuits molded into flexible flat-cable assemblies. Care needs to be taken with flexes to ensure optimum performance.
- Never crease or induce an extreme fold into an FPC, this may damage internal circuitry.
- Never allow pointed tools (even pen-points) to induce point damage to the FPC.
- Keep the "golden finger" area clean, including fingerprints (oils may result in intermittent contact) and scratches (they may cause open-circuits within the golden finger area).
- Make sure to lock the FPC into the intended mating connector fully and squarely.
- Never forcefully remove an FPC from the mating connector without first unlocking the connector mechanism.
- Train your assembly operators to carefully insert the FPC into mating connectors.
- Train your assembly operators to carefully remove the FPC from mating connectors.
- Train your assembly staff to properly handle the FPC assembly.
- Claims for "FPC-RELATED" damage due to improper handling won't be covered by the warranty.
Electrostatic Discharge (ESD) Damage
Good Display's products are electronic devices, commonly including sensitive electronic IC's and circuitry. Proper ESD handling is required to protect your devices from electrostatic discharge (common static "saps").
- ESD safety typically involves grounding users, test equipment, and tools.
- If soldering onto the PCB, make sure to use a grounded 3-prong soldering iron.
- Never carry unprotected materials without proper ESD-SAFE bags, trays, and/or covers.
- Make sure that all inspection, handling, and assembly personnel also demonstrate ESD-SAFE handling.
- Throughout the manufacturing and inspection process, Good Display ensures that your products are handled using ESD-SAFE techniques.
- Claims for "ESD-damaged" devices due to improper handling are not covered by the warranty.
Damage Discovered During Shipping
If damage is thought to have occurred during shipping, then carefully open cartons and inspect for broken glass or damaged goods.
- Customers should consider an INCOMING inspection if damage is suspected.
- Any type of damage claim will require photos, your freight forwarder will require this.
- If your shipment was insured, then FILE A CLAIM with your freight forwarder.
- Our shipping team is highly trained to ensure your products are carefully handled & packaged.
- If packaging is a concern for your product, then contact our Customer Service department.
- Claims for "BROKEN GLASS" are not covered by the warranty.

Cosmetic Imperfections
Good Display does their best in supplying the highest quality products, meeting our own internal quality standards.
- Display dots may be identified on displays produced for commercial and industrial products.
- The PCB is inspected multiple times for manufacturing defects, scratches, and exposed copper.
- Contact Customer Service if your product requires tighter cosmetic standards than those listed.
- Any warranty claim should exceed the sizes or quantities listed to be considered.
Cosmetic Standards
For small displays ≤ 4.2 inch:
- Dots ≤ 0.25 mm: can be ignored if there are no more than 3 per cm²
- Dots > 0.25 mm but < 0.4 mm: up to 4 allowed
- Dots ≥ 0.4 mm but < 0.5 mm: up to 1 allowed
For displays with a diagonal between 4.2 inch and 7.5 inch (excluding 4.2 inch):
- Dots > 0.5 mm: 0 allowed
- Dots > 0.4 mm but ≤ 0.5 mm: up to 2 allowed
- Dots > 0.25 mm but ≤ 0.4 mm: up to 4 allowed
- Dots ≤ 0.25 mm: ignored
For displays with a diagonal between 7.5" and 13.3" (excluding 7.5"):
- Dots > 1 mm: 0 allowed
- Dots > 0.8 mm but < 1 mm: up to 2 allowed
- Dots > 0.5 mm but ≤ 0.8 mm: up to 4 allowed
- Dots ≤ 0.5 mm: ignored
