Pervasive Displays (PDi) announces its new line of compact black, white and yellow e-paper displays. Ranging in size from 1.54 to 4.37-inches, the displays give product and service designers additional flexibility by being able to display text and images in yellow, as well as black and white.

E-paper displays (EPDs), commonly found in e-readers, have been growing in popularity across a range of sectors, thanks to their extremely low power requirements and easy readability in challenging lighting conditions, such as direct sunlight. Increasingly used in retail, logistics, building signage and the IoT, EPDs enable the use of digital displays where these would previously have been impractical or even impossible.

This new line of EPDs opens up fresh opportunities for organizations to enrich their customer experiences. Applications for the yellow tri-color displays include shop shelf labels, where yellow can be used to draw attention to special offers and price reductions. Shipping tags can incorporate yellow to highlight priority items. Corporate identification and access control badges often use one color for employees, another for contractors and another for visitors. EPDs enable these cards to be digitized, to include the person’s name and other details, with yellow EPDs used for one group, and black-and-white, or black, white and red EPDs for others.

Available in 1.54, 2.13, 2.66, 4.20 and 4.37-inch models, these active-matrix displays include an internal timing controller (Tcon), which minimizes the amount of programming and peripheral circuitry required. This results in a slimline display unit, and consequently a smaller overall device footprint, or additional space for other components.

The displays’ high pixel-density (ranging from 111 to 140 dpi, depending on the screen size) and state-of-the-art driving waveform, deliver exceptional image quality and the ability to display intricate patterns precisely. Meanwhile, because key capabilities are pre-programmed into the display, they can be driven without consuming resource from the host controller.

Pervasive Displays (PDi) today announced the launch of a new high resolution three color 12-inch Electronic Paper Display (EPD) module featuring an internal timing controller (iTC), the E2B98FS081. ( http://www.pervasivedisplays.com/products/122 ) The energy efficient, multi-colored display is a good fit for retail ESL (electronic shelf labeling), Point of Sale, office automation, and healthcare market applications. 

“These new 12-inch EPDs bring the clarity and impact of e-paper displays to a stunning new, larger format,” said Scott Soong, CEO of Pervasive Displays. “With sunlight-readability, they’re well suited to transportation, public information, and other markets where high visibility is valued.”

The E2B98FS081 is a 12-inch active matrix TFT three-pigment (black, white, and red), E Ink display panel. With a resolution of 103dpi, the display shows crisp, clear graphics and text. As E Ink replicates the optical characteristics of ink and paper, the EPD can be read clearly in ambient light without a backlight, or in direct sunlight, unlike traditional LCD displays. With three color options, the E2B98FS081 can create eye-catching informational displays, with colors being used to highlight critical information, product features, or promotions.

As a bistable display, the EPD module requires very little power to update an image and can maintain an image without power. Depending on the application, this means the E2B98FS081 can operate for days, weeks or even months on a single charge.

The highly integrated E2B98FS081 incorporates many features onboard which help reduce development time as well as cut BOM costs. Whereas many other EPDs rely on external timing controllers, the E2B98FS081 integrates a Chip-on-Glass timing controller on the display itself, along with a booster circuit to reduce the need for external components.

The timing controller stores pre-programmed driving waveforms tuned by Pervasive Displays to provide high-performance operation of the EPD. Besides providing strong, reliable optical performance and low energy consumption, the stored waveforms also greatly simplify display development and operation.

The high level of integration, thin profile and low power consumption features allow the E2B98FS081 to be used in very small or thin form factors, and in applications without the energy budget for a traditional display.

Pervasive Displays (PDi) announces a new TFT active matrix Electronic Paper Display (EPD) module that provides a dynamic, easily-readable display of information down to freezing temperatures of -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.

The display’s remarkable low temperature operation (from -25° C to 10° C), ultra-low power consumption, clarity and ease-of-integration make it suitable for new signage, labeling, tagging and informational applications in sectors and settings such as public information, retail, healthcare, transportation, warehousing, laboratories, cold-chain logistics, and food packaging and storage. 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, by using chip-on-glass technology to integrate the timing controller and other support circuits right onto the panel.”

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 building applications around this new module can reduce their component costs and shorten their application development time, as features like the integrated chip-on-glass (CoG) timing controller and booster circuit reduce the need for external driving circuitry and cut down software development overhead.

To ensure the best image quality, fastest display update speed, and greatest reliability, the timing controller’s one time programmable (OTP) lookup table holds driving waveforms, which control the series of electrical impulses that change the color of the e-paper display’s pixels. PDi’s stored driving waveforms also help to simplify programming, and to ensure the pre-tested waveforms are ideally tuned.
