Pervasive Displays lowers e-paper operating temperature for outdoor use

Pervasive Displays has announced a new wide operating temperature range for its Spectra e-paper displays (EPDs).

The range comprises 12 EPD modules with size options from 1.54 to 12.2 inches. The small, low power, active matrix EPDs can now operate from 0 to +40 degrees (10 degrees C lower than before) making them suitable for most indoor and many outdoor operating conditions, says Pervasive.

The bistable EPDs do not require power to display an image and use very little power to update the screen. The one time programmable (OTP) feature of each EPD module operates alongside the internal timing controller (iTC) to store an image waveform inside the display driver. The host processor does not have to load an image at start up, which reduces the time to display the first image.

The increased temperature range means that the screens can be installed in cold chain, healthcare and warehouse applications, Alchin Wang, general manager, Pervasive Displays. “And, as these EPDs all benefit from iTCs, we can offer customers a product which is smaller and lighter, saving them space on the PCB and reducing the bill of materials,” he added.

Pervasive Displays designs, manufactures and markets e-paper displays for applications which require high resolution, good readability and low power consumption, for example commercial and industrial applications including retail, logistics, healthcare, security and manufacturing. Its portfolio includes TFT, integrated circuit and e-paper platforms. Standard and custom displays are available, together with extensive technical support through an ecosystem of partners.

Design resources include detailed product specifications, application notes, reference designs, source code and applications support. The company is based in Tainan City, Taiwan and has offices in The Netherlands and Oregon, USA.
