Has anybody been successful at pulling this off. I need some information on how I can accomplish this. I have an old laptop that I would like to be able to use the monitor from to make a CarPC. I just can't figure out how to cable it and provide power.

I'm trying to find a mini lcd to use to display information. Sorta like the G15 has but in color. I was looking for lcds on ebay but could only find mini tv's that were expensive or computer monitors that go down to 13 inch. Does anybody know were I can pickup a small lcd around 4-5 inches maybe.

Do all digital picture frames (eg http://www.edgetechcorp.com/accessories/digital-picture-frame.asp) have transparent LCD's? Like if you take it apart, could the LCD still work but it is transparent? So you could turn it into a projector with a very powerful light?Thanks!

I have what I think is a broken lcd. It doesn't have any black blotches though. It is a spiderweb crack but has color in it. Is the lcd broken? What else could be wrong? The specs on the tv are Shap aquos 32 1080i .

I am trying to write HELLO on an LCD. It is a 16x1 (called WH1601A). I am using C18 language with ICD3. My 8 data lines are connected to PORTD[0-7]. My 3 control lines are connected to PORTB[0-2]. I can see 8 shaded boxes on my LCD which occupies half of the screen, but when i run the program nothing happens and the 8 boxes just stay there and nothing is written. I have been going at this for 2 days to no avail. I'm guessing the mistake is from the code, please take a look! Help will be much appreciated. #include #pragma config WDT = OFF //DEFINING PORTS #define rs PORTBbits.RB0 #define rw PORTBbits.RB1 #define en PORTBbits.RB2 #define data PORTD //Function prototypes void init(void); void LCD_init(void); void LCD_data(unsigned char); void LCD_cmd(unsigned char); void LCD_busy(unsigned int); void LCD_sendstring(unsigned char *var); void main() { init(); LCD_init(); LCD_sendstring("Hello"); while(1); } void LCD_sendstring(unsigned char *var) {      while(*var)              //till string ends        LCD_data(*var++);  //send characters one by one } //Initialize the LCD void LCD_init() { LCD_cmd(0x01);     //Clear LCD     LCD_cmd(0x38);     //Function set: 2 Line, 8-bit, 5x7 dots   //LCD_cmd(0x0C); // 1 line, 8 bit, 5x7;           LCD_cmd(0x0F);     //Display on, Curson blinking command                  LCD_cmd(0x06);     //Entry mode, auto increment with no shift    } void LCD_data(unsigned char var) {      data = var;      //Function set: 2 Line, 8-bit, 5x7 dots      rs   = 1;        //Selected data register      rw   = 0;        //We are writing      en   = 1;        //Enable H->L   LCD_busy(1);      en   = 0;      LCD_busy(15);          //Wait for LCD to process the command } void LCD_cmd(unsigned char var) {      data = var;      //Function set: 2 Line, 8-bit, 5x7 dots      rs   = 0;        //Selected command register      rw   = 0;        //We are writing in instruction register      en   = 1;        //Enable H->L   LCD_busy(1);      en   = 0;      LCD_busy(15);          //Wait for LCD to process the command } void LCD_busy(unsigned int itime) {          unsigned char i,j;          for(i=0;i             for(j=0;j<255;j++); } void init() { OSCCONbits.IRCF2=1; //oscillator frequency = 8mhz OSCCONbits.IRCF1=1; OSCCONbits.IRCF0=1; ADCON1=0xFF; //make ports digital TRISD=0x00; //PORTD output TRISB=0x00; //PORTB output PORTD=0x00; PORTB=0x00; en = 0; LCD_busy(250); } Any idea guys?! This is the first time i work an LCD and I could not find a problem in the forums. 

Hello im the new guy here and im wondering what can i do with these parts i had a lcd monitor and the motherboard is fried and jjust the screen is ok what can i do with him somehow to use it or something and also i have GPS motherboard it works fine it has a 8gb disk space i dont know what to do with her i have old motherboards for dekstop computer mini itx,msi..... and i have two laptops one the motherboard is fried and the other one doesnt have a problem but its too old and if somebady can give me some examples in what can i convert this things Thank you      

Well i dont know anything about lcd screens and i just aquiered one from an old pc and i want it to come to life again. if these help these are all the numbers and stuff on the back of the screen TORISAN TFT-LCM TM121SV-02L01 500F00023388O5 MADE IN JAPAN                                                                                       AR111A987K321129MS

Does anyone know the average power impute on a LCD display i need to test its backlight

I've been working on the OggVOSH... I was planning the screen & touch-wheel board when I realized that the screen, and the backup were both too big, ironically, was too big in BOTH dimensions!I've checked mouser & digikey, and neither have any LCDs that would fit in the space. By any chance, does anyone know of a really small color LCD? The board is 28x48mm, and I can't have it take up the whole board (but some stuff *can* go beneath it, I just need to account for the connector)

Hey guys I want to get started using simlpe 16x2 LCDs in my Arduino projects, but I I need one for beginners. Nothing too fancy. This is the one I'm looking at: https://www.sparkfun.com/products/709.   Also, if anyone knows where I can get one that has the three outputs( +5v, GND, and data) and/or has a link to a website, that would be extremely helpful. Thanks in advance!

Is there anywhere I can get a working transparent LCD screen? Graphical would be nice, but not vital. It doesn't need fancy colors or anything.

I have two broken lcd screen and salvaged only the backlight panel, power supply, and sreen display circuitry i it to light up all the time and not only 2 secs after you light it up without pluging any computer in the video ports. HOW? Thanks to all of you:)

I have been wondering this for some time now: How can I make my own lcd solution? I don't want anything that will be able to display a picture, what I'd like to do is make windows that can shade/unshade. It'd be only one pixel, so no fancy circuitry would be required.

Hello everyone, Just recently I took apart my broken CD Player hoping to find something useful to tool around with. I took out the LCD display, but now what? I have never worked with LCD's and never have learned about them. I have done some reasearch online, but I could not find anything that would help me put it to use other than in my CD player. I don't really know how I could put it to use, so if anyone has any suggestions, they would be greatly appreciated. Thanks -Brennn10

I'm building a little teleprompter, and I remembered my family had an old "broken" portable 7" dvd player. It turns out that just the little powerbrick was broken, BUT the display seems really washed out. Like, I hooked up an old Gamecube, and if you view it at an angle, you can see the little cube dancing around and everything, but if you look at it straight on (like most people), it's just a lot of bright white. Is it broken, or is there anything i can do to fix it? The color and brightness buttons do nothing.

Hello creative tech people, This is my first post so I hope I got it in the right section, and I did a lot of research before creating this post. I've been researching this for a bit, and I've gotten a sudden fascination with LCDs (mostly of the full color display variety) and I've been planning on making  custom tablet style PCs based on old laptops just for fun and experimentation but in my planning I hit a bit of a snag in regards to the screen. Since much to my dismay they weren't swappable and relied on a controller intertwined in the motherboard. There's also the inverter which I'm not sure how relevant it is to the project, This is a real issue for me because I wanted to use a variety of screens from big ones to tiny ones from smartphones or mp3 players. I was wondering three things: 1. Can you make a monitor connect to a different motherboard through the magic of soldering? 2. (if #1 is a yes) will the controller handle the different signal or does each one have a different driver format and all that aggravating frippery? 3. Would taking apart a standard vga flat screen monitor and using that instead of a laptop screen avoid the issue altogether? Or would it bring up new problems?

I have been given a dell lcd screen and want to hook it up to my dvd player, can i do that? if so how?

I have a 20" lcd tv with a broken controller in it  is there any lcd controller kit that would work good with a 20"  lcd screen mybad  its a 26"  Maxent MX-26X3 thanks 

I need a lcd monitor for a project. It needs to be somewhere between 17 and 21" inch. I don't have a very big price range but will pay for shipping. Thanks!!!

Hi i got this old LCD panel  see pics it is about 5.7 inches has tow wires cable and another 14 wires cable coming out of it has this writing on the back: FHS-0635 MEDMMPUU3W2F MADE IN JAPAN i need data-sheet or pinouts or anything like this?"i used Google and kinda failed" and how to connect it and control it ?"or this type of LCD s " and what is its applications ? any info or links ... thank u in advance :)

Ok i have one LCD from a welding mask and i need another. What i want to do is basically make auto-dimming glasses. I want this particular type because all i have to do is apply a few volts and the entire thing will dim, it makes things simple. Can someone please tell me where i can buy some if anywhere. Or give me a suggestion as to what else i could use.

I have a lcd moniter (acer V233H 22inch) but overnight it stoped working it will turn on  then display a black screen  PS my cable works if you need more ifo than that comment

Hi, I got an old piece of scientific equipment from ~1988 to 1991 range. Its got a pretty large LCD and I was wondering if I could use it later when I become better with electronics/hacking. Behind the lcd is a set of 8 (maybe 10, can't recall) HDM44104 chips. The lcd board is connect via ribbon cable to another board with 20 pins to connect to the instruments main board. Any ideas? ================================================================================= EDIT: I did some research and its a 10 pin LCD but how do i figure out the dimensions? Also, the board the LCD directly contains a RAM chip. What's that for? Thanks

I bumped my lcd monitor (not cracked) and it has dark spot now can this be fixed ?

Dose any one know ware I can get a single pixel bistable lcd display that is about 1inx2in

Hello i have from an old machine an lcd monitor (S-8209D) 64x128 pixels can i do anything with this or not? and if i can some ideas???? thanks?

. I was wondering if anyone knows a supplier for a FFC converter/adapter so I can replace a viao laptop LCD with an HP one I have on hand?  I'm trying to use on hand parts to build a diy lcd projector, and thee vaio lcd has serious issues that reduce it's usable screen real estate, IE, dead pixels, lines running top to bottom...  The HP just has a broken backlight, but it's motherboard is trashed. 

Just got a LCD 20X4 character screen. 10K pot connected to 5V. Can controll contrast. problem is, only 1/2 of it???"--------------FADED----------------""--------------DARK------------------""--------------FADED----------------""--------------DARK------------------"only 2/4 rows of character blocks go dark when full contrast. why is this!!!

I recently picked up a bunch of junk from a friend including 2 Optrex DMC40457 LCD's (and a bunch of what looks like telco circuitboards) I have never worked with LCD's before and I am looking for some ideas/ beginner guides for this model. The controller chip is a HD44780 if that helps.(bad) Picture: http://joshuaburgess.biz/gallery2/v/other/lcd.JPG.htmlhttp://joshuaburgess.biz/gallery2/v/other/lcd.JPG.html

Well, I'll get right to the point. I bought a LCD from goldmine-elec.com and it came in today. i have no expirence with lcd screens, and cannot find the pins required. the screen goes in a Kronos 4500 time clock, and has the following marking on the board. 9600009-002 REV.B 3601021 - 001 AVLOT # 48723-0201 EDT EW50107FLYU Please, anyone with more expirince, anyone have any idea how to interface this with arduino? TIA!

Hello instructables, I have an idea for a device but not the skill to build a prototype.  I am in need of someone with technical skill in microcontrollers and LCDs. The device I aim to create is basically an LCD watch or bracelet. Rather than time which is numerical, I need the watch to display words. It will be wearable on the wrist and therefore use a battery. No buttons or input are required for this project. I also don't need to make the case. I just need the working parts. I envision that this will require an LCD screen, a microcontroller chip, memory, and a battery for power. If you are interested, I will be happy to pay you for your help. If interested, please PM me so we can discuss what I am trying to make further. I am flexible on the design and hopefully it would be a fun and easy project a willing participant.  Again, I will pay for your time and components but this should also be a relatively fun and straightforward project for anyone who's worked with LCDs (e.g Nokia screens) and microcontrollers before. I look forward to hearing from you.  Take care. 

Hello I used a processing sketch that shows a graphic form of information recieved from a pulse sensor. I would like to take that information and display it on an lcd screen. I don't know how to take that data and send it out of processing and into the lcd, so I could really use some help! thanks

So thinking about ergonomics, I have this idea in my head of computer monitor that's a really light-weight screen on a stalk, like a bendy metal thing that you can position wherever you want so that it's at eye level and you can type without bending your neck all day looking at a laptop screen. The monitor would be wireless and would have a heavy base like a microphone stand so you could position it anywhere and then hang the screen in front of your eyes, whether you're on the couch or a chair or bed or a desk.But then I was thinking "You know, my laptop's LCD is not that heavy. I wonder if I could just put a stalk on it." :)Seems like the main problem would be lengthening the LCD cable. Does anyone know anything about the cables?Better cable pictures at http://www.flickr.com/photos/56868697@N00/tags/lcd/ (I don't know why Instructables imported them at such low resolution without any descriptions.)

Details I thought this was supposed to be optional.

My backlights fail only when I input a viveo source of any kind. If I power up in RGB with a composite video source pluged in its fine until I switch the source to composite(video1). this is true for any source. they include S-video, RGB, composite, VGA and tuner. its run on 12V, pretty much Identical to a computer monitor except more inputs. thinking maybe the inverter, any other ideas will be helpful???

Hello everyone! I am working on project that involves mounting a 19in LCD monitor onto a board. The monitor has 4 threaded holes in the back for mounting onto an arm or wall mount. I was wondering if anyone knows what kind of screws to use or has any advice on properly and securely mounting the monitor. The monitor is a Westinghouse 19" LCD. The whole project is going to be a small entertainment center for my monitor. I am going to attach speakers and accent lighting. I am doing this for a class project and drafting it in Vectorworks. *If anyone is interested in looking at the plans I will send them to you; however please don't redistribute them. They will be in DWG format. GC

I just built a DIY projector for my room (basically an overhead with an lcd and fans slapped on). Many people that do this use a 15 inch screen, but my family recently burnt out the backlight of a 17", so I used that. Anyways, since the stage of the overheadprojector can't see the whole LCD, some parts of the image get cut off. Is there some sort of software to essentially shrink a screen so that I can get the whole image viewable to the projector?

Hi have an LCD and finding a mount seems to be almost impossible. To attach a mount it first need to be recessed into the screen. The VESA dimensions are 200mm X 100mm. Does any one have any ideas as to as to how I can fix this monitor to the wall. The monitor is a Samsumg 2494HS Thanks

I have this lcd i need the manufacture but it only has a logo and i need to know the pins so i can hook up to arduino i have a pic of the logo i couldnt get a clear shot with camera but i made a pic of what it looks like i have

Okay, this might be a little confusing, so bear with me. I want to make a looping video of, say, Matrix code display on a small LCD screen, but I just want the little screen. Is there any way I could hook up a thumb drive or something to it to display that video in a loop?

Congrats! Instead of throwing away your broken LCD monitor, you've decided to fix it. What do you have too loose by attempting the repair yourself? It's already heading for the trash can or the e-waste center. By repairing it you will probably save from $100 to $200 or more! If you have done any reading at all on the web, you have already discovered that bad capacitors account for a large percentage of all LCD monitor failures. If your monitor flickers when you start it up, the screen is dim, has strange lines on it, clicks, etc., then this information is just for you! The repair does not require any special knowledge or skill. About the only tools you will need are a putty knife, a screwdriver, a pair of pliers and a Radio Shack soldering iron. Without getting into too much technical jargon, there are two main components inside your monitor, the power board which powers the inverter (lights) and video, and the video board. The power supply circuit board must be removed before you can replace the capacitors. You must open your monitor and examine the capacitors on the power supply board. Each monitor will have a power supply circuit board. Each monitor model will have a slightly different board. They all look about the same. Some have more capacitors, some have less. Most all LCD monitors have a large 400v capacitor. These rarely go bad. There's a video at www.youtube.com/watch that shows you how to disassemble a Viewsonic monitor, and install new capacitors. This is a great video! There's also a good tutorial that shows how to completely disassemble a Samsung 204T LCD Monitor. It's a step by step guide, which also includes a "how to solder" video. Although this tutorial is for a Samsung 204T LCD monitor, the information found here can be applied to almost any monitor. Between the YouTube video on the Viewsonic monitor and the tutorial you should have no problem installing new capacitors in your LCD monitor. Good Luck!

Is it possible to make a replacement screen for a tablet pc to be a cintiq-like external display tablet? I've seen replacement screens available on eBay as well as tablets that are missing components like hdd, keyboard, ram, etc which could be used to obtain said screen. This would not be a stand-alone device like a tablet, but a second display for either a desktop or a laptop that would function as a screen and tablet for input, a cintiq clone. Thanks

I am looking for lcd screens that could display information from a computer.  Small, at most 5 inches.  Also, im 13 and dont have an allowance so the cheaper the better!  I have tried really hard trying to find them and when i do its too expensive. HELP ME B(

Http://i00.i.aliimg.com/photo/v0/325133078/7_segment_LCD_panel.jpg Has anyone had any luck hooking up seven segment lcds to their arduino's? These have 4 seven segment digits, a :, and an am/pm display. They have less than 28 pins.

     I recently bought an Ipod touch that was at a discounted price because of two large dead spots.  They appear to be permanent, not just stuck pixels.  Recently though, there are now spots developing, but they're not the usual circles.  They are rows, one pixel wide and a dozen or so pixels long.  Every day they get a little bigger.  What causes this, and how can I fix it?

Hello humans. Here's the dealie. I have and older vaio laptop. The keyboard is going bad and the hard drive is also being foolish. In any case I don't want/use/need it anymore, but I would like to harvest the monitor and use it as a secondary for my other computer. I cant kind much on the subject. I pretty much need to know what to do to allow me to plug it into another computer and work. alrighty. thats all, thanks humans. -Bjorn

Hey guys i've recently received an Arduino Uno (tech-mas gifts !) and have started trying stuff out, i also had 2 old cellphones that i hadn't used for years, so i scavenged the vibrators and screens and left the rest untouched(no ripping appart, worry not) now i see that the screens both have a plastic thing with a lot if very tiny pins sticking out of them, and i wonder if there would be any way i can connect these to the arduino and use them as displays (was thinking of a smart-not-phone, wich does all the funny stuff a smartphone does without the phonecalls), please keep in mind i have a very basic set of tools (the arduino, a breadboard and the "starter pack"(with leds resistors ect...), plus a soldering iron, and would like to keep this project salvage based if possible (no money for smart-not-phones) info i could find on the displays: 1st one is a LMS240GF12,(non touchscreen) i couldnt find any info on this model but a few similar displays with lms241 or 242 names exist, so i guess the specs should be similar ? 2nd one is the touchscreen that came with a HTC Wildfire phone, and i think the display serial would be A3333 G8 but i'm not sure, none of the information is labelled and internet has been of little help as of now ^^. If you have any tips or need more info i'll be glad to receive them

Hello everybody,  I'm here to ask a question I'm not able to solve on my own. I'm not good at programming, so it may be a silly question, but I can't find a solution. I'm building an Arduino based humidity and temperature monitoring system, with three DHT-11 sensors and a display to show readings from them. I'd like to be able to toggle LCD's backlight on with a pushbutton and have the code switch it off after a while. I can't  figure out how to make Arduino do it.
