EPD gate driver can power segment or active matrix displays

Operating with a maximum clock frequency of 50MHz, the device supports 3-level gray scaling and enables bidirectional data transfer. Suitable to drive segment or active matrix displays, multiple IXEP1400 can share a common data bus. Further to this, data entered via the shift register input controls the pixels of the display.

The IXEP1400 is a cost reduced and lower power version of the MXEI1480 EPD source driver. The IXEP1400 can be used with the IXYS ICD's new IXEP2300 300 channel gate driver to provide a complete driver solution for EPDs. The device has been designed for use in wearable mobile devices, portable battery operated mobile devices, secondary displays for smart phones and tablets, eBooks, electronic shelf labels, smart cards, and signage.

“EPDs are the latest thin and energy efficient ‘paper’ based flexible displays that are suited for a wide range of applications. These displays are very energy efficient and are visible in all light conditions and are low cost and do not need any backlighting like LCDs. IXYS ICD has been developing the IC technology to drive these displays and now introduce them as ASSPs (Application Specific Standard Products) in the market,” commented Mark Heisig, General Manger of IXYS ICD.

The IXEP1400 is available as gold bumped die, supplied in wafer form, or in waffle pack carriers.
