Summary of SPECTRA E-PAPER DISPLAYS OPERATIONAL FROM ZERO TO +40°C
Pervasive Displays has expanded the operating temperature range of its Spectra e-paper displays (EPDs) to 0°C–40°C. These 12 active-matrix modules, ranging from 1.54" to 12.2", are ideal for cold chain, healthcare, and warehouse applications. Their bistable nature ensures minimal power usage, while the One-Time Programmable (OTP) feature and internal timing controller (iTC) enable faster image loading and reduced system size by eliminating the need for a host processor to load images at startup.
Parts used in the Spectra E-Paper Displays:
- Spectra e-paper display modules
- Active-matrix technology
- One-time programmable (OTP) feature
- Internal timing controller (iTC)
- Display driver
- Host processor (optional/not required for startup)
- PCB (Printed Circuit Board)
Pervasive Displays (PDi) has announced a new wide operating temperature range for its Spectra e-paper displays (EPDs). The Spectra range comprises 12 EPD modules with size options from 1.54 to 12.2”.
These small, low power, active-matrix EPDs can now operate from zero to +40°C (10°C lower than before) making them suitable for most indoor and many outdoor operating conditions.
EPDs are bistable, meaning that they require no 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. As there is no requirement for the host processor to load an image at startup, the time to the first image is reduced, improving the user experience.
Alchin Wang, General Manager, Pervasive Displays, said:
We’ve increased the lower end of the operating range of our Spectra EPDs down to zero from 10°C. As the uppermost temperature they are capable of operating in is +40°C, these low power screens are now a great option for a variety of applications where reliability is paramount such as in cold chain, healthcare and warehouse setting.
“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.
