low power lcd display price

Do you need a display that draws the lowest current possible? Want long lasting battery-powered LCD project? Well, you have come to the right place. We compiled this list of digital displays that consume the least amount of power. These displays are perfect for when you are trying to extend the battery life of your product by pulling the least amount of current possible.

Other than a pen and paper, ePaper provides the lowest power consumption available for electronic displays. It does this via an electrochemical process that requires zero power once the pixels are in their desired location. These displays are ideal for when the content is not updated very often. Low-power ePapers only use power during updates, so the longer time between updates, the lower the power consumed.

The beauty of OLED displays and power consumption is that OLEDs only draw current for pixels that are on. For instance, when displaying a black and white checkerboard pattern, an OLED display consumes 50% less current than when displaying a completely white screen. Keeping that in mind, user interfaces can be designed to conserve as much power as possible by limiting how many pixels are lit.

This is a thin, extremely low-power 128x64 graphic LCD display module. It has no backlight, so consumes no power illuminating the display. However, if you wanted to backlight the module, the rear polarizer is transflective, so you could add your own lighting solution there. This display is perfectly suited for hand-held or any application requiring low power consumption or a very thin display. A row of icons is shown automatically top of the display without having to be rendered. This display has an integrated controller and the tail is designed to mate with standard 18-conductor 0.5mm pitch ZIF connectors (typical would be Omron XF2L18351A/ DigiKey P/N OR754CT-ND).

I"m drooling over Sharp Memory LCD, but they are pricey. I mean $40 is not terrible for one, but I need to get a bunch for battery powered LCD boards I"m working on

From my breadboard tests ATmega328p board w/ Nokia 5110 is using 140-170uA (depending on number of characters on display) when chip is sleeping which is not bad at all, but I want to explore all alternatives...

Alas I don"t know of a display that matches your requirements (price/power) and apart from an e-ink or memory LCD that updates vary rarely I don"t think you will ever get one to run for a year on 2x AAA batteries.

The reflective version (without backlight) of the DOGS102 might meet your requirements. According to the datasheet, the current will be 250uA for LCD and LCD-Controller (if I interpret the datasheet correctly).

Yeah you could be right. Besides display I forgot that I need to keep radio module awake, that eats a lot of power. But how they heck do they do this with commercial temperature/humidity devices? I have one that"s been running for 2 years on single AA battery

My commercial module only last about 6 months on 2x AAA. It would probably last longer without the LCD to display temperature/humidity and flash an LED every time it transmits (every 30 seconds). Your doing very well with yours, must have one of them plutonium batteries.

Note that these do not use the highly multiplexed display system with the bias ladder of the graphical or 1602/ 2004 devices, they are generally one pin per segment so the electronics is far more efficient.

Darn. I"ve been searching and it seems everyone in Arduinoland uses OLEDs and TFTs. I want a 1" display that I can run off of a coin battery for a year. I know they exist, I own a bunch of them. But the best thing I"ve found draws 125uA.

That"s a 2.2" display. I"m looking for a 1" display, like many of the little OLEDs you can buy on eBay for $5 or less. But with 1/500th the power consumption. My $10 wristwatch has a display like that.

It appears that you simply haven"t weighed up the real issues. If you finally get a display with 1/500th the consumption of what ever, all you get is that but, if that is what you need, the real problem isn"t the display and never was. It"s the Arduino that drives it.

I"m not planning on using an Arduino. Why would you assume that? If the display drew 20uA instead of 10mA it would still be the major consumer of current.

Fair enough. What"s an Arduino? AVR (and non-AVR) chips are also discussed in this forum. But even an official Arduino board like the Pro Mini, with the regulator isolated, is capable of drawing a very low average current.
