Hi All,
Searching the net and Ebay... can't seem to find a LCD akin to those of digital watches, needing no backlight to make the characters visible... 
I have power requirements to meet and those 1604 displays found on Ebay with 50-100mA when backlight on simply wont do.
Could someone please point me to a low power lcd display needing no backlight (20x4)?
TIA,
Pedro
Have you considered the OLED displays? These tend to be graphic devices so you would not be able to use them on limited memory processors like ATtiny85 based Gemma, Trinket, or Digisparks. For example, this 128x64 display from Adafruit is claimed to draw about 20maH on average: Monochrome 0.96 128x64 OLED Graphic Display - STEMMA QT : ID 326 : $17.50 : Adafruit Industries, Unique & fun DIY electronics and kits, and this 128x32 display is claimed to draw about 15maH on average: Monochrome 128x32 SPI OLED graphic display : ID 661 : $17.50 : Adafruit Industries, Unique & fun DIY electronics and kits
This Sparkfun 7 segment display lists a max. forward current of 20maH: 7-Segment Display - 4-Digit (Yellow) - COM-09480 - SparkFun Electronics
If you are using something smaller like an ATtiny85, you can communicate with this device using serial, i2c, or spi and you don't need to keep a graphic map of the display in the microprocessor. It has a max draw of 20maH: Mono OLED--0.96" Serial: UART/I2C/SPI 128x64 OLED Display Blue DS12864OLED-2B...
Thank you Michael for that list.
In fact I should have been more specific as I've already seen those....
Every one of those are just too small. I'm looking for a reflective alphanumeric LCD about the size of those 20x4 displays commonly found on Ebay .
TIA,
Pedro
