low power lcd display arduino pricelist

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.

This graphic LCD module acts as a shield for Arduino Uno-style microcontrollers. The pins on the carrier board match up to the Arduino Uno"s ports, so the module simply presses on and is fully and correctly connected. Plus, this carrier board is able to be connected to either a 3.3v logic level or a 5v logic level device. (Read our blog post if you have questions about logic level.)

This module is also available with a white-on-blue graphic display, or as a fully built kit with an included Seeeduino (Arduino Uno clone) loaded with code to demonstrate the graphic display.

In one of our previous tutorials we did an introduction on how to use the Nokia 5110 LCD  with the Arduino, the tutorial covered displaying texts with different fonts etc. For this tutorial, we are taking things a little bit further and will be working through the display of customized graphics on the Nokia 5110 LCD display. This tutorial will particularly be useful for those who want to display their brand logo or any other kind of image on the LCD asides ordinary texts.

The Nokia 5110 display is basically a graphic LCD display useful for a lot of applications. It was intended originally to be used as a screen for cell phones and was used in lots of mobile phones during the 90’s. This display uses a low powered CMOS LCD controller/driver PCD8544, which drives the graphic display of size 84×48. In a normal state, the display consumes about 6 to 7mA which makes it quite ideal for low power usage.

To interface with a micro controller and power itself, the display has two parallel 8-pin port to which headers pins can be connected. You can pick one of the sides and solder header pins to it for connection to the Arduino board.

There are two main power sources needed. The first one is the operational power supply which according to the data sheet should be between the range of 2.7V to 3.3V.  The second power supply is required for the LCD back-light. The LCD circuit has no current limiting resistor inbuilt so its better to play safe and only power with 3.3V max.

For the purpose of this tutorial, we will be using the paint.net tool to create the graphics. It is easy to use and can be downloaded from here. One thing that should be kept in mind while creating the graphics or logo is the canvass size. Since the LCD is 84×48, its important the canvass size is same as the screen, to ensure the designed graphics shows perfectly on the display.

In order to load our own graphics into the Arduino to be displayed by the Nokia 5110 display, we will need to use the LCD assistant software.  It is a free and easy to use software that converts bitmap images into a data array which can then be used in C programming language based firmware for any micro-controller. The software is available for download here.

Then save output (Also found under file) as Graphics.c. The file can be previewed using a tool like notepad++ and your output should look something like the image below.

For better performance, we can save the data array in the program memory of the arduino instead of the sram, to save as much space as possible. To do this we will need to include some line of code to the data array file as shown in the image below.

With the LCD initialized, we then move to the loop proper. For each of the graphics to be displayed, we first clear the screen using lcd.clrscr() and then draw the graphics using lcd.drawbitmap() with the coordinates, name of the file, and the size as parameters. update the display with lcd.update() and set a delay to give the graphics enough time to display on the screen.

Copy the code, paste in the Arduino IDE, and upload to your Arduino board, you should get an output like the image below on your screen. Don’t forget to include the Graphics.c file in the Arduino sketch folder.

LCD character modules are “characteristically” simple display devices known for their very low power consumption, low cost and long-term reliability. They are designed to display alpha-numeric characters in preset patterns and do not have much. In most cases, they are small displays with only 8 or 16 or 32 characters, utilized for status reports and simple communication. It is the most popular display for hobbyist because of its ease of operation.

Orient Display offers many standard sizes including (characters x lines) 8×1, 8×2, 16×2, 16×4 , 20×2, 20×4 , 24×4, 40×4, and many more. Orient Display’s character LCD displays cover small LCD character display modules for tiny devices to large character LCD displays for medical equipments.

Orient Display character LCD modules use industrial standard Hitachi HD44780 controller or compatible controllers such as Sitronix ST7066U, Samsung S6A0069, so they can be quickly integrated into a new product or used as a replacement in your existing products.

The LCD panel technologies include TN, STN, FSTN, FFSTN or VA (Vertical Alignment) types and also with positive mode and negative mode and options of reflective, transflective or transmissive polarizers. There are different LED backlights available in various colors including yellow-green, white, red, blue, green, amber, and RGB LEDs as well as no backlight option.

The viewing angles for these character LCD displays are available with 6:00, 12:00, 3:00, and 9:00. Orient Display offers various IC options of character fonts including English/Japanese, western European, eastern European, Scandinavian European, Cyrillic (Russian), and Hebrew/Arabic. These LCD character modules and LCD modules can be used on industrial and consumer’s applications including printers, microwaves, water machines, medical devices, car and home audio, white goods, game machines, toys, industrial meters, etc.
