How fast do your EPDs refresh with global, fast and partial update?

29 Aug 2022

Generally, our monochrome EPDs take 2-3 seconds for a full refresh (Global update) while tricolor takes 10 more seconds. Fast and partial update takes more than 700 ms (our recommendation) for optimal performance between optics and speed.

Does three-colored e-paper display screen support fast/partial update?

28 Aug 2022

The three-colored EPD does support fast update but could oftentimes result in serious E-ink ghosting and a much slower update rate compared to a monochrome EPD as the red pixels refresh at a slower speed. We highly suggest you select a monochrome EPD for fast update implementation.

Does your E-ink e-paper display support direct sunlight readability?

28 Aug 2022

Our EPD (E-ink e-paper display) is designed for indoor or semi-outdoor environments. Placing an EPD under direct sunlight can lead to degraded image quality while refreshing the E-ink screen as the strong light could cause current leakage.

What happens if my e-paper display module needs to be operated over the defined operation temperature range?

28 Aug 2022

Your e-paper display will still be able to function outside of the high and low operation temperature range, but you will not expect a comfortable image quality and issues like lower contrast ratio, E-ink ghosting, or blurred image could happen. Please be aware that if the EPD is placed outside of our storage temperature range, deformation and permanent damage could occur.

If I have E-ink ghosting issues with my e-paper display, how can I resolve it?

28 Aug 2022

E-ink ghosting could happen when a fast/partial update was done without a proper driving process. Our fast update driving waveform embedded display (part number E2###PS0##) could help. Please follow instructions and insert a full white and black image to help fix the issue, or take a video to share with us for further review. Please also contact us and take video to show us your encountered ghosting phenomenon.

How do your e-paper development kits work with e-paper screens?

28 Aug 2022

Our EXT3-1 kit supports working with a full range of EPD size models. The EPDK kit includes an all-in-one demonstration to showcase how the graphic library works. If you need interactive applications, our EXT3-Touch kit can help achieve the goal with touch EPD.
