2.87-inch and 4.2-inch Spectra Displays
Tainan City, Taiwan, 11 October, 2016 – Pervasive Displays (PDi), a world leader in e-paper displays (EPDs), has announced the availability of the first two products in the Spectra family. These three-pigment black, white and red EPDs are now generally available. There is growing demand for color EPDs to help retailers gain a competitive advantage. Three-color displays attract consumers in environments with constantly changing market conditions. Pervasive Displays’ Spectra EPD quickly draws attention to specific messages on displays and signage. Key applications include electronic shelf labels (ESL), industrial displays, smart cards, and identification badges.
Display Specifications
The Spectra EPD is an active matrix TFT glass substrate display with a super-wide viewing angle of 180 degrees. Two sizes of Spectra EPD are currently available. Model E2287ES051 is a 2.87-inch display providing a resolution of 296 x 128 and pixel density of 112 dpi. The larger model E2417ES053 is a 4.2-inch display with 400 x 300 resolution figure and 120 dpi high pixel density. In both displays the pixel arrangement is vertical and the surface of the display features an anti-glare treatment. Accordingly, Spectra EPDs are able to display fine graphics and patterns, maximizing visibility, recognition and impact.
Three-Color Technology
Extra thin and very light, Spectra EPD uses a SPI interface and features fine-tuned embedded waveform for exceptional optical performance. The embedded waveform can be custom configured to meet the needs of different customers and applications. Although not new in the marketplace, the three-color technology used by Pervasive Displays benefits from Pervasive Displays’ ongoing development programme. This delivers better quality, enhanced reliability, and improvements to color film variations.
Due to their bistable nature, Spectra EPD panels require very little power to update and use zero power to maintain an image. The displays are able to operate over an ambient temperature range of 0 to 40 degrees and breakage detection is supported.
Pervasive Displays has already shipped several million Spectra units to its lead customer. These displays are now available to the wider market.
