6.3 AC CHARACTERISTICS

2.66inch e-Paper (G) User Manual

6.3.1 MCU INTERFACE SELECTION

The 3-wire/4-wire serial port as communication interface for all the function and command setting. 3-wire/4-wire engine act as a “slave mode” for all the time, and will not issue any command to the 3-wire/4-wire bus itself. Under read mode, 3-wire/4-wire engine will return the data during “Data phase”. The returned data should be latched at the rising edge of SCL by external controller. Data in the “Hi-Z phase” will be ignored by 3-wire/4-wire engine during write operation, and should be ignored during read operation also. During read operation, external controller should float SDA pin under “Hi-Z phase” and “Data phase”.

HANDLING, SAFETY, AND ENVIRONMENT REQUIREMENTS

WARNING The display glass may break when it is dropped or bumped on a hard surface. Handle with care. Should the display break, do not touch the electrophoretic material. In case of contact with electrophoretic material, wash with water and soap.
CAUTION The display module should not be exposed to harmful gases, such as acid and alkali gases, which corrode electronic components. Disassembling the display module can cause permanent damage and invalidates the warranty agreements.
Observe general precautions that are common to handling delicate electronic components. The glass can break and front surfaces can easily be damaged. Moreover the display is sensitive to static electricity and other rough environmental conditions.

Data sheet status

Product specification

This data sheet contains final product specifications.

Limiting values Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability.

14. PRECAUTIONS

2.66inch e-Paper (G) User Manual

(1) Do not apply pressure to the EPD panel in order to prevent damaging it. (2) Do not connect or disconnect the interface connector while the EPD panel is in operation. (3) Do not touch IC bonding area. It may scratch TFT lead or damage IC function. (4) Please be mindful of moisture to avoid its penetration into the EPD panel, which may cause
damage during operation. (5) If the EPD Panel / Module is not refreshed every 24 hours, a phenomena known as “Ghosting” or
“Image Sticking” may occur. It is recommended to refreshed the ESL/EPD Tag every 24 hours in use case. It is recommended that customer ships or stores the ESL/EPD Tag with a completely white image to avoid this issue. (6) High temperature, high humidity, sunlight or fluorescent light may degrade the EPD panel’s performance. Please do not expose the unprotected EPD panel to high temperature, high humidity, sunlight, or fluorescent for long periods of time.
