Black, white and red e-paper displays can operate from 0°C to +40°C
The company’s Spectra range is made up of 12 EPD modules that feature size options from 1.54 to 12.2 inches. The compact, low power, active-matrix EPDs are able to operate from 0°C to +40°C (10°C lower than previously). The new low-temperature capability allows them to be used in the majority of indoor applications, as well as some outdoor ones.
EPDs are bistable, which means that they need no power to display an image and they use very little power for screen updates. The one time programmable (OTP) function of each EPD module operates with the internal timing controller (iTC) to store an image waveform in the display driver. There is no need for the host processor to load an image when the screen is started up initially, reducing the time to first image and improving the user experience.
“We’ve increased the lower end of the operating range of our Spectra EPDs down to 0°C 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,” said 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.”
