General Guidelines

Consider the Following Aspects to Determine the Best Fit for Your Application:

Update Cycle:

• ePaper Displays are suitable for update cycles ranging from tens of seconds to minutes.
• Most black-and-white electronic paper screens from Good Display have a fast refresh rate of 1.5 to 2.5 seconds and partial refresh rate of a few hundred milliseconds.
• Ideal for applications where a static image is maintained without constant electricity and doesn't require frequent refreshing.

Temperature & Colors:

• Note that Multi-color ePaper displays cannot operate at sub-zero temperatures.
• For operation under 0℃, the Wide temperature ePaper display (black and white) is the only suitable option.
• If having a Multi-color display is not essential, we recommend selecting Monochrome Display.
• Good Display can also broaden the operating temperature of ePaper display by adding heating film.

Guidelines for Safe Handling and Usage of ePaper Display

• Do not press the IC area or the FPC-to-glass bonding area with your hands, as this can easily cause IC damage from static discharge or FPC detachment.
• The FPC is bonded to the glass edge by only 1mm. When handling the ePaper display, please hold it by the glass part and do not lift the product by grabbing the FPC, and is not allowed to be bend upward.
• Please turn off the power before plugging or unplugging the ePaper display, as failure to do so can easily cause IC damage.
• Please check power supply capacity of battery. Weak power capacity will also burn out the IC.
• Always use devices within the rated voltage and current limitations. Powering beyond these specifications will result in irreparable damage.
• Always follow ESD-safe handling techniques. Be sure to ground the human body and electric appliances during work. Preferably, use a conductive mat on the table & wear conduction processed fiber. Synthetic fiber is not recommended.
• Inspect products before use to ensure it meets pre-specified quality standards. Don't remove our manufacturer's plastic liners if the product does not meet our quality standards or it's defective.
• Wear gloves or finger cots to prevent electrical contacts or glass surface contamination.
• Always follow proper soldering techniques and ventilation requirements.

Handling and Operation Precautions for ePaper Display

Assembly Guidelines for ePaper Displays

• Prior to assembly, remove the protective film from ePaper display.
• ePaper displays are delicate and should be handled with care to avoid excessive pressure during assembly.
• The tape location also needs to be considered, for example, the "口" shape is easier to dismantle than the "|||" one.
• ePaper display ICs are sensitive to static electricity. Implement strict measures to prevent static discharge during assembly, operation and storage. Keep ESD below ±200V.
• Some displays use ACF bonding techniques for their FPCs. To prevent damage to the bonds and potential electrical disconnections, it's important to limit the load to less than 1 kg.

Operation Conditions and Design Notices

• Sunlight Exposure: Avoid exposing the ePaper display to direct sunlight as it can potentially damage the film.
• Strict Compliance with Specifications: When designing the driving circuit, adhere strictly to the provided specifications.
• Update Intervals:
  • Allow at least 180-second interval after completing a set of display updates
  • For Multi-color ePaper displays and Full color ePaper displays, perform a full update at least once every 24 hours
• Partial Update: After every 5 partial updates, perform a full update on the ePaper display to prevent ghosting on the screen.
• Deep Sleep Mode: If the interval between updates is long, it is recommended to either disconnect the power supply or set the ePaper display to deep sleep mode.
• FPC Bending Position: The bending position of the FPC should be about 1.0 to 1.5 mm away from the glass edge and Curvature radius R>0.5. Flexing other parts of the FPC is not permitted.
