Transparent LCD's

Do all digital picture frames (eg 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!

LCD & PIC18F4520!

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?!

Help with LCD

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

broken lcd?

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.

Paid LCD Project

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.

Arduino and scavenged LCDs

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

Problem with LCD backlight

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. All I could make till now is Arduino switching backlight ON at the beginning of the code regardless of the buton being pressed or not.  Here is the code I wrote, I bolded the part relative to the pushbutton.

Optimum size would be 15 by 25mm but obviously that is impossibly as this for the main display. To be used as a computer right next to your eye; (I am using focusing lenses) (Raspberry pi) Brilliant is around 15 by 25 Good is 20 by 35 Kinda bad is 3.5 by 3.5 Preferably detached from board (wires-  unlikely) and rectangular ratio. Must be Raspberry Pi Compatible. UK please! You guys here, are incredible that you can answer me and my persistent waffling and stupid questions for free, so thanks so much. Regards Rowan
