Tainan City, Taiwan – 12 April 2018. Pervasive Displays (PDi), a world leader in e-paper displays, today announces a new low temperature e-paper display module. The TFT active matrix EPD provides a dynamic, easily-readable display down to -25° C (-13 °F). This low temperature, low power, high resolution display module is the 2.13-inch E2213HS091. The module is highly integrated, with a built in timing controller and other support circuitry to help designers speed up product development.
Application Areas
The display’s low temperature operation from -25° C to 10° C delivers ultra-low power consumption with easy integration. It suits signage, labeling, and IoT applications across retail, healthcare, transportation, warehousing, cold-chain logistics, and food packaging. Typical application areas include electronic shelf labels (ESL), Internet of Things (IoT) devices, retail freezers, e-POP (point of purchase) and signage, electronic bulletins, and navigation.
“E-paper displays that work reliably in sub-zero temperatures are opening up a new frontier of applications as these products outperform older technologies,” said Scott Soong, CEO of Pervasive Displays. “We’re also making those new applications easier to develop and reducing time to market. We used chip-on-glass technology to integrate the timing controller and other support circuits right onto the panel.”
Technical Highlights
The E2213HS091 uses TFT active matrix monochrome E Ink display panel technology. Text and graphics are sharp and clear thanks to the display’s high resolution. Unlike older LCD technology, E Ink displays provides a vibrant, natural light-readable display without needing a power-hungry backlight.
Thanks to its bi-stable nature, EPD module technology requires no power to maintain an image and very little power to update an image. Developers can reduce component costs and shorten application development time with this module. The integrated chip-on-glass (CoG) timing controller and booster circuit minimize external driving circuitry and software development overhead.
The timing controller’s one time programmable (OTP) look up table holds driving waveforms for optimal image quality and display performance. These waveforms control the electrical impulses that change each pixel’s color. PDi’s stored driving waveforms also help to simplify programming, and to ensure the pre-tested waveforms are ideally tuned.
