nokia lcd module made in china

I had a project that needed some live data display, and looking for the cheapest low-power solution for our loggers lead me to the Nokia 5110 LCD. Once you get the backlight current under control, you can power the entire display from a digital pin, and if you use shiftout for soft SPI you can then get rid of the Reset and CS control lines. This brings the display down to any four wires you can spare on your build (incl. the power pin) and a ground line. This is much more manageable than what you see with the standard hookup guides if your mc is I/O limited like our pro-mini based loggers:

This LCD (I have the old-old kind) is absolutely my favorite. Yes, it has a board-to-glass connector that ranges from bad to abysmal, but it offers such a simple interface and so many pixels for so little money (obviously less if you buy only the panel.) Here are some clever things I"ve discovered:

Will fully operate on as little as 2.0V. That"s power (Vdd) and i/o. It can be driven at 2MHz at these speeds; in fact, the LCD will work at even lower voltages but the contrast fades quickly and your microcontroller will likely approach its lower voltage limit too.

The LCD will work with the chip-select pin (SCE) tied to ground. This means that if it"s the only device on the SPI bus, don"t bother framing the i/o with a chip-select pin. If the bus is shared, frame the entire transaction, not every individual byte you send to the LCD. Interestingly, the display also seems to work fine with a floating Vdd pin - it must draw sufficient power just from i/o via clamping diodes; not surprising when you consider how low-power it is.

The Vout pin: Looks like you don"t have to worry about it on this product, but the bare LCD will generate positive 6-9V on that pin. This wasn"t totally clear to me from reading the datasheet.

(5) If you are using a PIC to run ths thing, and using the PIC"s USART or EUSART in a synchronous mode, be sure to note that the LCD controller expects the MSBit of each byte to be transmitted first on the serial line. The PIC 18F EUSART transmits the LSBit first. For now, I have lots of extra code space, so I"ve wasted a 256-byte section on a lookup table that reverses the bits in a byte. This way, I just write my initialization code normally, and I have a TransmitCommandByte() function that looks up every byte it sends so I don"t have to think about that.

Thank you! I"m not quite sure I do want an LCD yet, to be honest, I"m just considering the different options available. I"ll check out the Sharp component, thanks!

Advice for others: It took me quite a while to get this working on an ARM Cortex. Since there is no way to read from the LCD, it is very hard to know if SPI is working without doing everything perfectly. SO:

If the LCD module is soldered to another board and the two top screws installed and tightened carefully to pull the bow out of the module it seems to prevent (or solve) the problem.

I"m using voltage dividers to supply 3V in the inputs of the LCD, because of the Arduino works in 5V. LCD Vcc and LED are powered from the 3.3V output of the Arduino. The LCD only displayed something when I used: R1=470K,R2=820K. I have tried several values to obtain 3V, but the LCD showed nothing. I don"t understand that.

I"m interfacing this LCD with ATMEGA 32. Its been more than a week that I"ve been trying to get it right. All I get is the LED dimming effect. Here is my initialization code..CE=1;

I have a similar board made by mib-instruments and bought from ebay years ago. It has been my standard spi test tool because it"s so easy to work with. http://www.ebay.com/itm/Nokia-5110-LCD-84x84-dot-martix-backlight-PCB-RED-/320684678723 (specs http://i1119.photobucket.com/albums/k636/mib_instruments/diy/LCDC2A0SPEC.jpg)

I almost have it working satisfactorily but I find that the bottom 1/5th of the screen does not function correctly. Sometimes it has some random blocks that are black, most of the time it is blank. I am not sure what would cause this. Is it safe to assume it is a defect on this module?

These LCD"s need cleaning. I have an average failure rate of about 15-20% on delivery. The most common problem is that the contrast is too high, and there"s constant flickering / changing of contrast compared to the other 80% of them.

The solution is fairly simple, unclip the LCD from it"s board and clean the pads on the PCB with 99% IPA. Then remove the lcd back plate and contact bar. Sometimes the contact bar is stuck fairly well to the glass, peel off carefully. Clean the contacts on the LCD glass with IPA, if any residue from the contacts is left on, rub it off carefully with IPA / tissue.

I love this little display! I wanted to be able to create images for it but nothing I saw did exactly what I wanted. So I wrote a processing sketch that creates 84x48 squares on the screen and allows you to click to turn them on or off. Also has buttons to invert, move up/down/left/right, and flip horizontally/vertically. Then, it saves the hex data to a text file to copy to your code. You can also load an image (any size, any colors) and it will scale it, convert to b/w, then put it in the rest of the program so that you can alter the pixels or move it. It isn"t perfect for every occasion but I"ve found it useful and I hope others might too. It is heavily commented so it should be easy to figure things out and change them if you want something different. http://thewanderingengineer.com/2014/07/12/nokia-5110-screen-photo-to-bitmap-converter/

Anyone taken these things apart yet? You know the flexible rectangular blocky thing that connects the contact pad on the board to the LCD itself? What are these called?

Got mine running last night and found two problems with the code, one of which was the backslash a couple of others have already noted. Second was that the LCDCharacter() writes two blank vertical lines, one before the character and a second after, when only one is needed. Without the extra blank you get at least one additional character on each line. I"ll probably also move the ASCII font table to PROGMEM space to save on RAM and then start to work on some big digits for a clock.

I"m using this LCD for a large Arduino UNO project, but I"m running out of SRAM memory space. I was wondering if I used PROGMEM on the LCD ASCII array if that would help. If so, does anyone know what the right code for this would be? After looking through a lot of PROGMEM examples, I"m not advance enough to really grasp everything that"s going on. Any help you can give would be a great help. Thanks in advance!

I used one of these LCDs with an Arduino to display GPS information. I wrote a few functions that can display large numbers (28 px high) if anyone is interested, this lets me display speed, heading etc. A writeup of my project is here: http://mechinations.wordpress.com/2014/04/07/gps-sailing/

These are great displays. I ran into a problem using them with the nRF24L01+ radio transciever, which requires the use of the SPI bus. If one attaches both the radio and the display MOSI and SCK pins to pins 13 and 11 as instructed in the hookup guide, the SPI traffic of the other device (in this case the nRF24L01+ radio) will prevent the display from functioning. The easy solution is to move the Nokia 5110 MOSI and SCK pins to any other digital pin. This should be made clear in the hookup guide, where it says there is no choice but to use the hardware SPI pins for the display. I found out that is not true at all. I hope his helps others with the same problem. Despite the occasional bad display these carry much more information that the comparably prices 16 x 2 LCD and use fewer pins too boot. What a deal!

This is a great display for the money, certainly the best bang for the buck of you can live with B&W and lower res graphics. I have a lcd driver for Arduino I will post on http://www.marchdvd.com/5110 so take a look there it draws text aligned on pixels boundaries of 8 and draws lines and has invert video options.

I just started messing around with this LCD using a STM32F103 microcontroller running at 72MHz... it works great. The only problem I had, and I suspect others might have if they are using fast processors, is that you have to deliberately introduce the setup and hold time delays on the DC pin... if you don"t you will get spurious pixels written to the display. I used a delay of 10uS, although the spec says 100nS is fine.

I just spent the last couple hours struggling with this LCD because of something very stupid of me. I was using an atmega328p in AVR-GCC and using hardware SPI. Thinking i didn"t need MISO I hooked it to DC. The LCD worked absolutely fine until I tried to set the x and y position in the ram. It started acting weird every time I tried it. Finally I put dc to another pin and BAM NO PROBLEMS. Looking back I feel pretty stupid but hopefully this post will save someone else the same mistake. Other than that great LCD for my projects

The Energia folks have an example program for this LCD and the TI Launchpad written using their Arduino style tooling. I"ve updated their example and added the ability to report back the temperature over a UART. It is a very simple hardware setup since both systems are 3.3v. http://joe.blog.freemansoft.com/2012/08/digital-thermometer-with-ti-lanchpad.html

I tried using the "LCDAssistant" package to create a logo from a graphic that I resized to a b&w jpg of 84x48 but every byte generated was 0x00 so that was not right. I tried fiddling with the settings (flying blind) but still got nowhere - does anybody know the settings for LCDAssistant and this display and has used it successfully?

One of the things that I test regularly is a commercial item that features a 16x4 (HD44780) display. Currently I have a 20x4 on a flying lead that I plug in to determine if a display failure is down the lcd display or the main board.

Might I suggest you (SFE) source some of the Electronic Assembly"s LCD Dog-S series. I think they would be a step up from these at a reduced price. I don"t think that they website is up to date, but their part number is LED39x41-GR.

I made a little font generator for the Nokia 5110 in the processing programming language (processing.org). It allows you to convert any font and any character that you can display on the screen into a list of hex codes that can be directly used in an embedded system (I"m using msp430). Just type a character and the corresponding hex codes will be in your clipboard and you can copy them into your program. It starts with an example with the chinese character for 5. It should work on any system that can run processing (e.g. mac osx).

I finally got around to running this LCD on my 3310 PCB. It is working fine with one minor problem. The SF 3310 display hides to first line of bytes for some reason and I had to offset everything to compensate. The 5110 doesn"t do this as behaves as expected. I haven"t heard anyone else report this so maybe my initialization code is different.

Using a 3V source, my LCD often worked OK using bias 0x14 like the other examples, but sometimes it would appear gray and faded. The fading would lessen if I touched the panel lightly with my hand for a few seconds, then let go, so maybe it"s a temperature-dependent thing?

Ack! After two days of working nicely with 0x15 bias, I reset the board today, and the LCD appeared way over-dark. I changed the bias back to 0x14 and it looks perfect. What the heck?! I think there must be some temperature-sensing or temperature-dependence going on, so the same init values may produce good-looking results one day but not the next.

If you are having problems with the black pixels in images/warping PCB, use original Nokia 5110, I happened to have one at home and it works as it should, no bad connections degrading image quality.

Does anyone know whether this can be stripped of its backing so it can be used in transmission? I would love to use this as a modulator for a laser beam. Or if someone knows a similarly cheap transmission LCD that would be fine too.

Stuck. Blank LCD. Added 0x20, changed Vop to 0xB3. Guessing connections may be the issue? 3.3v for LED and VCC. GND to GND. Remainder connected to Arduino via voltage dividers. What am I doing wrong?

This is a great little lcd. When I first wired it up, the backlight was shorted (accidentally) against my 5v rail, so i got some magic smoke, and burnt to LEDs but it re-soldered the offending joints and it works very well now. Something to note: the refresh and write times are much, much slower if you use 5 volt logic. I stuck in a logic level converter and it ran at least 5x faster.

You can also use FastLCD to convert your bitmaps - google it. It outputs BASIC code, but you just search and replace &h to 0x and you"re grand. It has the added advantage of being an editor for touching up output.

I recently obtained a virtually identical LCD from a Nokia 5160, and although its backlight LEDs are green, not white and conversely use different voltages, I had success hooking up the LEDs" Vcc pin to a PWM capable pin on the microcontroller, allowing me to control backlight intensity (I didn"t need a current limiting resistor for this either, but adding one will help reduce current drain on the controller).

Seems like the PCD8544 library does it"s own SPI bit managing and it really doesn"t like me using the SD library (also talks SPI) at the same time. I"ve made sure I"ve got all the SPI pins matching for both libraries (MISO, MOSI, Clock are the same and each device has it"s own Select), but it looks like the SD.begin() call just breaks the SPI bus for the 5110 and it becomes non-responsive. The LCD works just fine if I don"t initialize the SD library and the SD card works fine if I do initialize the SD card.

I"m pretty sure I tracked down the problem- the PCD8544 library uses software SPI while the SD library uses hardware SPI and I"m pretty sure the Arduino can"t do both over the same SPI clock/miso/mosi pins. Anyone know if this LCD will work with hardware SPI?

I"ve had issues with the LCD not showing anything intermittently. You got to make sure that all the connections are secure, and for the reset pulse, be sure to have a delay that"s 30-50 milliseconds long.

As much as I love SFE products and will continue to order from them, this is one product I would not recommend. The connection between the LCD unit itself and the carrier board is via those rubber polymer connectors. All the planets must line up properly for them to work. In this case, the carrier board was warped preventing the connection from working. You will find other such remarks in the comments area.

Don"t do this. Each divider will be burning 20x the entire amount of current that the display needs to function, and the whole assembly will waste 100x the LCD"s needed power and many, many times more than even the atmega needs to run at full speed. This will kill battery life.

Hi, I just bought this wonderful LCD but I"m having huge huge problems connecting it..could anyone please point me in the right direction? Since there are pins that aren"t metioned in the code, for example the 6 - DNK(MOSI)...

Does anyone know the diode rating and package size, also does anyone know where to get the rubber ferroius connector behind the LCD mine is defective. Has anyone come into issues with the breadboard the LCD is connected to, a few aren"t working for me.

Yes, we have noticed that the PCB was bowing and as a result the LCD now only works when we press down on the metal strip at the top. I hope that only a small number of these LCDs have this problem. We"re expecting a shipment to arrive today, I will be running more tests.

Edit: After leaving glue to dry overnight, LCD simply does not turn on anymore. All the connections are good, but absolutely nothing shows on the LCD now at all. Only the LEDs come on.

Did you get either of the LCDs to display anything, at any time? Is it possible that the connections were OK, but you were not initializing or driving them correctly? Or did they start to work at one point, and then fail at some later point?

Note that the backlight LED"s are soldered onto the breakout board, and have nothing to do with the circuitry of the controller and LCD. So just because the backlights are shining doesn"t tell you anything about the operability of the LCD itself.

It depends on the code that you are using to control the LCD. If you are using the Arduino example above, the pins are defined in the beginning of the code.

FWIW I have connected this LCD with a 5V power supply to a 5V Arduino board with no level conversion and it worked. Presumably this may reduce the lifetime of the LCD.

I am attempting to use this with a Duemilanove (ATmega328). Up til now, I have been powering it with the 3.3V line, including the LED. The datasheet for the LDC claims: "VDDmax = 5 V if LCD supply voltage is internally generated (voltage generator enabled)." The logic levels should be kept from 2.7V to 3.3V. Since the Duemilanove uses 5V logic levels, I am using a simple voltage divider on the communication line with no issues.

The maximum logic value of 3.3 volts made me cautious of driving the LCDs at the native 5 volts of my Teensy AVR. That said, running purely off 5 volts seems to do no harm to the LCD.

For those interested, I have taken a few measurements of the current draw of the LED backlight of my LCD. As I said earlier, powering the LED with 5V external has caused permanent damage to one, perhaps two of the four LEDs. So, use the following graph at your own risk.

Is there any more documentation available for the additions to the LCD? For example, the datasheet has no information (that I could find, at least) on the LED. Everything seems fine on 3.3V, but what is the current limit on the LED? (note: if it wasn"t for work, I would just mess around with it myself.)

Here is a PicBasic Pro example for the 3310, which should be compatible with the 5110. http://www.picbasic.co.uk/forum/content.php?r=174-Using-Nokia-3310-LCD

Fantastic! It appears from your example link that this uses the same controller as the Nokia 3310 that I"ve already used in past projects. The only thing that made it so cumbersome was trying to connect to its fine pitch press on type connector. This gives me a great low cost display option that is easy to connect to.

If anyone doesn"t have experience with this LCD, take a peak at the Arduino example link above to see just how easy it is to use. If you use plain C on your AVRs, I have sample code on http://tinkerish.com.

The listing says that these are new (at the bottom of this listing), these screens are actually recycled/pulled screens from actual Nokia Phones and devices in China. Because of this, there may be small blemishes or imperfections or even nicks. This is unavoidable at this point. This screen has not been manufactured for many years now. We have to take what we can get. Its still a great screen and Vetco Guarantees functionality.

This is LCD Graphics Display is straight forward to hook up and quick to get running with your Arduino or other microcontroller. At only 1.72" x 1.72", this display is easy to integrate into just about any project. The bright blue LED backlight illuminates the display from either edge.

This module requires both 3.3VDC Power and uses 3.3V Logic - To inteface this module with the 5 Volt Logic of an Arduino, we suggest our NTE4050B Non-Inverting Buffer Chip.

The name of this product itself is enough to explain its origin. Yes of course !!! this LCD module was used in old Nokia 5110/3310 cell phones. Now it has been widely used by hobbyists for graphics, text, etc. Though it’s an industrial module, this LCD display is extremely easy to use. The Nokia 5110 is a basic graphic LCD screen for lots of applications. It was originally intended for a cell phone screen. This Nokia 5110 LCD Display Module is mounted on an easy-to-solder PCB. The Nokia 5110 LCD Module uses a Philips PCD8544 LCD driver, which is designed for mobile phones. Nokia 5110 LCD Display Module is a low-cost monochrome LCD module comprised of 84 X 48 pixels that can be used to display rich graphics and text content. This module is a revision that accepts 3-5V input. So no extra level shifter is needed. It uses the PCD8544 controller, which is the same one used in the Nokia 3310 LCD. The PCD8544 is a low-power CMOS LCD controller/driver, designed to drive a graphic display of 48 rows and 84 columns. All necessary functions for the display are provided in a single chip, including on-chip generation of LCD supply and bias voltages, resulting in a minimum of external components and low power consumption. The PCD8544 interfaces to microcontrollers through a serial bus interface.

Can use conductive glue to connect the module to the printed board, without cables. The metal hooks on the module can fix the module on the printed board, which is very easy to install and replace

These 84 by 48 pixel black and white LCDs are what you might be found in an old Nokia 3310. They’re not flash, and they don’t have a lot of display real-estate. But they are easy to control. If you’re looking to step up your project’s with user interface (UI) game from simple displays or LEDs, this graphic LCD is a good place to start.

before we display our first image and real time sensor values on this LCD, let look at the pinout for this LCD, To interface with Arduino and power the graphic LCD, there are two, parallel 8-pin headers above and below it, flipping the board over, you will find the labels for each of the pins.

To supply voltages on the LCD,the most important supply voltage — VCC — which  supplies the logic circuits inside the LCD. The datasheet sates this should be between 2.7 and 3.3v. in normal state, the LCD will consume about 6 or 7mA

3.3V  is required for LED back-lights on the board. if you were to remove the LCD from the PCB (not that you should, or need to), you’d see that these are back-lights in their simplest form- four white LEDs spaced around the edges of the board. You may also notice that  there aren’t connected to any current limiting resistors.

Built into this LCD is a Philips PCD8544 display controller, which converts the massive parallel interface of the raw LCD to a more convenient serial one. The PCD8544 is controlled through a synchronous serial interface similar to SPI. there are clock(CLK) and data(DIN) input lines, and an active-low chip select(SCE) input as well On top of those three serial lines, there another input -DC-which tells the display whether the data it’s receiving is a command or displayable data.

The PCD8544 LCD controller has flexible yet complex drivers. Vast knowledge on memory addressing is required in order to use the PCD8544 controller. Fortunately, Adafruit’s PCD8544 Nokia 5110 LCD library was written to hide away all the complexities so that we can issue simple commands to control the display.

Filter your search by typing ‘nokia’. There should be a couple entries. Look for Adafruit PCD8544 Nokia 5110 LCD library. Click on that entry, and then select Install.

This will give you complete understanding about how to use the Nokia 5110 LCD display and can serve as the basis for more practical experiments and projects. Try the sketch out and then we will dissect it in some detail.

Nokia manufactures a wide variety of cell phones and many of their cheaper phones contain simple LCD"s which may be used in microcontroller projects.  There is one particular LCD model that is used in a wide variety of their phones and is often referred to as simply a "Nokia LCD", or "Nokia 6100 LCD".  I used to use a Nokia 2600 phone and whenever I upgraded I took the Nokia apart to remove its LCD.  This LCD appears to be the same one that is sold as "Nokia 6100 LCD" and I was able to get it up and running with a bit of work using an AVR.

You will need some sort of breakout board in order to connect the display.  Sparkfun sells several (a standard breakout, an Arduino shield, an Olimex module, etc) as well as the bare surface-mount connector.  Since all of SparkFun"s boards include the LCD, I just bought the connector and made my own breakout board since I already had the LCD.

If you don"t have a breakout board, you need to first make some sort of connector for the LCD.  My first attempt was to solder thin magnet wire to each leg of the connector with a fine-tip soldering iron.  This took several tries but eventually I got it connected.  I then applied generous amounts of super glue to make sure it wouldn"t come apart and soldered on some thicker wires to connect to the microcontroller.

After you have a breakout board for the LCD connector, you must connect it to your circuit.  There are 10 pins on the connector, one is unused.  The LCD has four control signals (Clock, Data, Reset, Chip Select), two 3.3V inputs, two grounds, and a backlight input.  The LCD driver circuitry runs on 3.3V as do the control signals.  However, the backlight requires a higher voltage around 7V.  Using a 1K ohm resistor between the backlight power and a 12V power supply seems to work well, the voltage is around 6-6.5V which makes it bright enough to use.

Since the LCD protocol is 9-bit SPI, you cannot use the hardware SPI interface found on many microcontrollers (including the AVR series microcontrollers) as they often only support 8-bit mode.  This means that you will probably have to implement a software SPI output.  Electrically, this means you can connect the four control lines to any unused I/O pins on your microcontroller.  Your microcontroller must be running at 3.3V to connect the lines directly, otherwise add 10K ohm resistors on each line to limit the current going into the LCD.

The LCD has many functions that are available by sending commands over the SPI interface.  The important ones are explained here and will allow you to get your LCD up and running.  A full set of commands is listed in the PCF8833 datasheet here:

Before you can write to the LCD, it must be initialized.  First, the Reset line must be pulled low for around 100ms and then raised high again.  The Reset line must remain high during operation.  Then, a sequence of commands must be sent, in the following order:

Continuing with the protocol, once the LCD is initialized it is ready to draw.  Drawing works by first defining a region to draw and then streaming pixel data to fill that region.  It is confusing at first, but if done properly is more efficient than pixel-by-pixel drawing.  A region is simply a rectangular area on the screen.  We"ll say it begins at point (X1,Y1) and ends at point (X2, Y2).  Once defined, the LCD controller will fill in pixels from left to right starting at (X1, Y1).  When it reaches the edge of the region, it will jump to the next line [in my example, (X1, Y1+1) ].  It does this until it reaches (X2, Y2) at which it stops accepting data.  If you only want to draw one pixel, you simply set (X1, Y1) and (X2, Y2) to the pixel you want to draw.  This defines the region as a single pixel.  Any data sent after the first pixel"s worth of data is discarded.

To implement the 9-bit protocol using an AVR, I found a nice ASM function in the SparkFun example code.  I modified the code some to clean it up and adapt it for the Phillips controller.  This ASM code is more efficient than using regular C and allows faster LCD writes.

Rectangles are incredibly useful.  You can draw one big rectangle to clear the screen, use them for menu elements, indicators, check boxes, frames, text backgrounds, and much more.  Thankfully they are easy to draw on the Nokia LCD"s.  All you need to do is define a region the size of the rectangle and fill it in with a solid color.  The following AVR C code (using the functions described in the last section) will do this.

Although this is a graphical LCD, it is still useful to be able to print text to it.  Unlike character-based LCD"s, graphical LCD"s do not contain a character map or font table or anything.  To print text to a graphical LCD, you must define your own font table in your code and then print it character-by-character using the table.  In my code, I have provided a font table (one that I converted by hand because I couldn"t find a good program to do it for me).  The font is 6x8 which should allow you to fit plenty of text on the screen.  I have provided functions for printing characters as well as strings.

With rectangles and text down, we can begin making truly useful stuff.  Menus allow users to select from a large number of options with only a few buttons (Up, Down, and Select are common).  To make a menu that looks good, you need to format your screen and text properly.  I wanted a single title line and the rest to be menu entries.  The LCD is 130x130 (usable) pixels in resolution.  This means that I have 130 vertical pixels to divide up into menu lines.  Since my font is 8 pixels tall, I decided that using 10-pixel-tall menu lines would be good.  This gives a 1 pixel border around the text on top and bottom, 13 total menu lines (1 title + 12 entries), and up to 21 characters per menu line.

When drawing moving objects on the LCD, you can greatly speed up the frame rate and eliminate screen glitches by only redrawing the moving parts of an object rather than redrawing the entire screen or entire object.  For instance, if a ball is moving across the screen, rather than redrawing the entire ball you can just draw the pixels along the edge that has moved and clear the pixels on the edge that has moved away.  Techniques such as frame buffering and double buffering can be used, where a new frame buffer is compared against an old frame buffer and only differing pixels are written to the display.  However, given the limitations of AVR and similar 8-bit microcontrollers, these techniques are probably out of range.  If you are using an ARM or other 32-bit microcontroller with a higher performance CPU, more RAM, etc. then you can take advantage of double buffering for a much more efficient screen drawing system.

It is actually very easy to draw full color photos on the LCD!  I simply used the serial port to transfer the image from the PC to the AVR which displays it on the LCD.  To convert the image into the correct format, I wrote a small application in Visual Basic (VS 2010) that takes a 130x130 .bmp formatted image and transforms it into the 12 bit per pixel color format needed to display on the LCD.  The Visual Basic VS2010 project is included with the code package at the end of this Instructable.

I have posted example code for both AVR and 8051 microcontrollers as I have used the LCD with both.  The code was originally written for ATMega168 based on the SparkFun examples for both the LCD and Arduino LCD Shield.  I added text and menus then ported it to 8051 for use on my 8051 project board.  I then revised many systems which have been backported into the AVR code.

Have you had luck with your project? I am not familiar, but it appears the display in such vehicles is usually not an LCD of any kind, but a vacuum fluorescent discharge tube display, VFD. It"s a collection of thin shaped glass vacuum tubes that are coated with a Luminophore on the inside that determines their colour; correspondingly, while they can be manufactured in various colour, their colour can not be changed afterwards. I am not aware of any possibility to get a custom one-off VFD made for you.

It"s possible to reverse engineer the signals driving the display, and then create a drop in replacement, based on a microcontroller interpreting the signal and driving a graphic display of some kind, an LCD or OLED. With OLED, there is the question of suitability to vehicle use. The displays aren"t intended to run for hours on end, they degrade with use. Also their brightness is typically 10 times weaker than VFD. Also very few colours are available, you may be stuck with a colour that is more similar to that of VFD blue than your chosen LED blue. With LCD, there is an aesthetic issue with lowered contrast and potentially bad viewing angles. Monochromatic LCDs usually allow replacement of LEDs lighting them, and also LCDs with adjustable RGB backlight are available. An advantage of using a graphic display on a microcontroller is that you are not stuck with static symbols, you can adorn them with effect graphics, such as the frame of PRNDL gliding across the display or magnifying the currently active mode, beautiful, easily legible font for your odometer, etc.

Do you have a photograph of your display at hand so i know whether i"m thinking in the right direction? I am thinking of a display which has PRND321, a set of 7-segments for odometer, a couple of extra symbols around, but no text capability. If you have text dot matrix display which has distinct single-pixel spaces between the characters, it"s likely an HD44780 signal-compatible VFD, and you can get HD44780 LCD replacements. They come with width of 8, 16, 20 and 40 characters and height of 1, 2 and 4 lines.0

The "Message Center" appears to be an LCD it illuminates 2 colors, orange for some advisements, red for others i.e. low battery. I would like to change the color to blue or maybe green when it lights up as part of normal starting and vehicle going thru its checks. Any thoughts you have on this would be greatly appreciated.

Message center is a monochrome graphics LCD. You shall probably find some SMD LEDs on the board beneath it, that can be replaced. I am not familiar with specific display model employed, nor are there any data sheets - it has apparently been manufactured by Optrex Corporation, Japan, specifically for use by a division of General Motors, and has not been available generally or used anywhere else. Most companies wouldn"t be caught dead ordering or a 45x28 LCD. For reference, the display model designation is DMF-50796H. If it"s anything like i imagine it to be, there should be a metal shield retained by twisted tabs on a PCB, and merely removing the shield should give you access to the LEDs.

An interesting hack, with possibility of grand destruction, is inverting the LCD. On top of the glass is usually a polarization film that can be peeled off and replaced with one mounted 90° off-angle. Tough luck if the filter is instead sandwiched between glass layers.

Dear friends,i have nokia 2600c2 and nokia 2700c mobile. I need lcd datasheet used in these mobile. Do any budy have any idea where can i find it. I tried google but no use.2

I read that it can be easily controlled via any 3 wire interface (which I am planning to software implement with a sort of loop till get a kind of 9-bit serial with enable/disable) in the datasheet, but as it"s the driver datasheet it only shows the whole driver IC pinout instead of the 10 pin nokia LCD connector. I don"t know how to connect it, I am afraid of damaging it. The display is currently working (with the phone) so if I could connect it, then it should work or show anything more than a black background.

i am doing a project on high speed photography controller. in which i have to interface nokia 6100 lcd with the ATMEGA 32 IC for setting parameters. i have the nokia 6100 LCD, but have few questions

I posted the pinout as well as the commands. The circuit is described above as well, it"s pretty simple if you take the time to look at the documentation of the LCD and read through the code. Note that Instructables is not in any way a professional help organization for your immediate needs, and no, I will not contact you in dire emergency because you didn"t read the code or pinout all the way through, because you would"ve learned all 3 of those things by doing so. Plus, no two setups are exactly the same, you can"t expect me to spit out your particular circuit...you have to do some of the work yourself!0

Nokia Lumia 920 is a smartphone developed by Nokia that runs the Windows Phone 8 operating system.Qualcomm Krait CPU and a 4.5" IPS TFT LCD display, as well as a high-sensitivity capacitive touchscreen that can be used with gloves and fingernails;Gorilla Glass and has a 9 ms response time.PureView camera with OIS; it was the first smartphone camera to implement that technology,Qi inductive charging.

The Lumia 920 was released to mixed to positive reception. Most critics noted the device as the first Windows Phone 8 device to truly match its Android and iOS competitors in hardware, with high-end specifications, a Nokia PureView camera and unique features such as wireless inductive charging. Following this, the Lumia 920 would frequently be listed among the "elite" group smartphone during its time, otherwise populated by heavyweights from Apple and Samsung. This represented the first time a Windows Phone device had been considered to have powerful and impressive enough hardware to qualify as a truly high-end flagship device. Many features such as the super-sensitive capacitive screen and wireless inductive charging were popularised by the device and were found in later high-end Android phones. The Lumia 920 went on to win 12 awards.

Some reviewers criticised the thickness and weight of the Lumia 920, so Nokia released the Nokia Lumia 925, a lighter and thinner version of the Lumia 920 with an aluminium bodyNokia Lumia 930, successor to the Lumia 92x series, was announced at Build 2014 on April 2, 2014.

The Nokia Lumia 920 shares the "Fabula" design language of its predecessors, the Lumia 900 and 800, as well as the Nokia N9, with a unibody polycarbonate shell.

The Lumia 920 has a 4.5-inch (114 mm) curved Gorilla Glass display with a resolution of 1280x768 (WXGA) and an aspect ratio of 15:9, using enhanced IPS screen technology which Nokia calls "PureMotion HD+".

The Lumia 920 has Nokia"s PureView technology on the rear camera,optically stabilised 8.7-megapixel BSI image sensor (1/3.2" sized, much smaller than the previous Nokia 808 Pureview) with a f/2.0 Carl Zeiss Tessar lens, short-pulse high-power dual-LED flash and 1080p HD video capture. Pixel size is 1.4 μm. The front camera encloses a 1.3-megapixel sensor capable of capturing HD video at 720p.

On September 6, 2012, Nokia apologised for an advertisement showing a video supposedly shot from somebody holding a Lumia 920 on a bike, but which was actually shot by somebody holding a camera in a van (as it can be seen in the reflections on a window).

The Nokia Lumia 920 runs the Windows Phone 8 operating system. As with other Lumia devices, the 920 includes Nokia-exclusive apps, such as Nokia City Lens, an augmented reality software that gives dynamic information about users" surroundings using the camera.

It also includes Nokia"s HERE suite of apps, which provide offline maps, worldwide turn-by-turn voice-guided navigation and public transit information.Nokia Smart Shoot, which lets users capture selected parts of a photo by using a lens for the camera app that takes a number of photos in quick succession.

On December 19, 2012, Nokia started rolling out the Portico update for the Lumia 920 and 820, which also included a firmware update for the 920 with camera fixes and battery improvements.

From August 16, 2013, Nokia rolled out the Amber update, which is pre-installed on the Nokia Lumia 925 and 1020 and includes several camera and performance improvements, to every Nokia device running Windows Phone 8.

From approximately January 13, 2014, Nokia rolled out the Black update to Nokia Lumia devices running Windows Phone 8. Notable features include an enhanced glance screen and a new camera interface as well as a new Storyteller app.

In the UK, the Lumia 920 was released on November 2, 2012.EE (who operate T-Mobile and Orange in the UK) as one of the LTE-capable smartphones. Nokia have reported that the device will lose the EE-exclusivity in the UK, and will be available on the Vodafone and 3 networks from January 2013.

The initial stock market reaction to the Lumia 920 (and the Lumia 820, announced on the same day) was immediately negative. During the product announcement, Nokia shares closed down 16% on the day.

The Nokia Lumia 920 received mixed to positive reviews. Many critics noted the Lumia 920"s hardware as the first time a Windows Phone device could truly compete with the hardware of high-end Android and iOS devices. Critics praised the screen, camera and unique features of the device, while also criticizing the phone"s heft and thickness. CNET rated it 4 stars out of 5, praising the screen, attractive design, great Nokia-exclusive apps and an enjoyable OS, while the negatives were the unimpressive battery life and heavy weight.

Adam Z. Lein from Pocketnow wrote: "Our final rating is going to be a 8.3 out of 10. The hardware, the screen, the camera, the sound quality, the video stabilization, and Nokia"s custom apps are all extremely impressive. The pricing is pretty great too. The only negatives for me are really the large size and lack of user-replaceable battery. Everything else on this phone is top notch."

Initial sales reports and positive reviews of the Lumia 920 and 820 caused Nokia"s shares to rise over 40% in December 2012, although analysts warned that the number of phones sold would fall far behind market leaders like Apple and Samsung.Yle, then-CEO Stephen Elop said the positive public feedback had improved morale in the company.

On January 10, 2013, Nokia released preliminary financial information for Q4 2012, saying that it had sold more than 4.4 million Lumia devices in that quarter.
