I'm not sure if those are included in the estimate. Also I don't want to sound like I am shilling for Samsung, but there are various power saving options on the device. The energy guide states 87 kWh per year at 5 hours per day so roughly 48W per hour rather than 118W so drop that yearly cost down around $100. I'm not sure where you are getting that 118W number. And the parking signs have been running 4 years non stop any failures in the field. ![]() We did not see any problems with display. About 6/7 years ago we've launched a product based on epaper that was water tight and was intended to be used outside (permanent mounting on desks). Realistically EPD robustness is a solved problem. There are special waveforms that extend the operating range to beyond that, but you will get only black and white updates. Make sure you respect the maximum temperature limits - the driving board should be aware of extreme (>50C temperatures) and prevent updates in those cases. This is a solved problem with loads of companies using EPD for external usage. Failing to do so will cause permanent damage to the screen. Protect the screen against UV (there are protective foils and glass with integrated protection you can use). ![]() There are a couple of things you need to do: So we do have quite a lot of experience running these screens in extreme environments - we've worked with a company called Mercury Innovation and built a fleet of traffic signs that have been running in scorching Australia non-stop for about 4 years now. You can also shoot me a direct mail to luka.birsa AT. If anyone would like to get more information about E Ink, please shoot - we've tried every E Ink display out there, played with color display and probably seen every E Ink application out there. Check out what our partners are doing in this space (a recent live deployment. The market for outdoor displays - especialy smart bus stops that run on solar - is starting to ramp up. In offices it can be used as interactive signage - we've built a very successful solution for meeting room booking around it (see ).Ģ. We tried a lot of applications, some covered previously here on HN, we currently see that there are just two other avenues where E Ink is being used and has the potential for mass depoyments in the near future.ġ. I hate to say it, but the only way we could have brought the price down with current quantities is if we built an inferior product as the price right now is the function of Bill-of-Materials. E Ink in the non-reader, non-shelf label applications is still a very niche solution, that will command very high price. ![]() We've worked for years on getting the price down for the E Ink screens (trust me on this), but there is a question of critical mass. And since this is not a mass-mass produced product (at least not in a sense of your 75" OLED TV) you get to the price that you have. E Ink screens are very pricy (compared to LCD). I do see a lot of comments regarding the price, so it's best if I do the general disclaimer. I'm so happy when these kinds of posts surface as this is exactly how we've envisoned our platform to be used - by tinkerers builidng interesting ideas.
