Taiwan’s Pervasive Displays has introduced two electronic paper display modules, the E24581JS084 5.8-inch and E2969JS084 9.7-inch.

The tri-color modules offer bi-stable image resolution of 134 dpi and 121 dpi respectively.

The displays feature integrated timing controllers, an operating temperature range of 0-40°C and one-time programmable (OTP) capability.pervasive displays

These additions to Pervasive Displays’ portfolio are designed to meet the demands of more challenging environments like healthcare, out-of-home digital signage and information displays, while remaining suitable for retail applications such as electronic shelf labelling.

By integrating the timing controller, manufacturers can create simpler designs.

The potential reduction in PCB area and bill of materials could also allow a reduction in total size and weight, or more space to be dedicated to the battery, allowing the displays to operate even longer on a single primary cell, Pervasive Displays suggests.

The OTP feature of the E24581JS084 and E2969JS084 works alongside the internal timing controller, allowing an image waveform to be stored inside the display driver, thereby removing the need for the host processor to load an image at start up.

“A key benefit of EPD technology is its persistence when power is removed,” explained Alchin Wang, general manager, Pervasive Displays.

“The E24581JS084 and E2969JS084 EPD modules build on this by providing greater resolution and a larger display size that can be used in a wide variety of applications where reliability is paramount, such as cold chain food logistics and healthcare.”
