what is a lcd display quotation

Liquid crystal display (LCD) is a flat panel display that uses the light modulating properties of liquid crystals. Liquid crystals do not produce light directly, instead using a backlight or reflector to produce images in colour or monochrome.

There are two points we have to emphasize:Outer Dimension and Main Application. There are the most important factors and it is necessary for us to know them. If we don’t even know the outer dimension and the main application, we don’t know where to start.

If you like collecting quotations like I do, then this instructable is for you. This instructable will show you how to put together a way to display your quotes for all to see, using things you probably already have around the house.

Any kind of quote will do, but because the picture frame scrolls through the images that will contain the quotes it works best if you keep the quotes short. Longer quotes, although interesting, may not remain on screen long enough to be read. If you have a number of longer quotations, see "Some Final Notes" at the end of this instructable for tips that you can consider for longer display times.

Look at the sample images stored on your LCD picture frame. For my frame, all of the sample images were 856x480 pixels. To determine this, right click on the image file, and select Properties. You should see a number of tabs, one of which should be called “Details.” Click on the details tab; under Image you should see a width and height. Write this down or keep the window open, because we will use it to set up PowerPoint.

Take the smaller of the two numbers (usually the height), and divide that by the larger number. In my case, 480/856=0.5607. Checking the table below (which shows common screen image ratios), I can see that the native images on my LCD picture frame are just about in 16:9 format.

Open PowerPoint, and start a new presentation. On the ribbon, click Design, Page Setup. In the setup dialog box, select the image format that matches the native format of your LCD picture frame. We do this because it helps prevent the software driving the frame from cropping or stretching the images unnecessarily. Click Home on the ribbon.

Now, look for the New Slide button. In the lower-right corner of the button, there should be a small arrow. Click on the arrow, which should bring up a bunch of options for slide layouts. Select the Blank Slide.

At this point, your presentation should have two slides: The initial default title slide, and your newly inserted blank slide. Click on the first slide (the title slide), click your right mouse button, and select delete. You should be left with a single blank slide in your presentation, sized to the native image size of your LCD picture frame.

In many cases, the picture won’t fill the slide because it’s in a different format than the native format for the LCD picture frame. Thus, we’ll need to resize the image to fit. At the same time, we don’t want to distort the image either. Here’s the most straightforward approach:

Move the image all the way to the right edge of the PowerPoint slide, then up until the top of the image aligns with the top of the slide. The image should “snap” to the edges of the slide.

Grab the lower-left corner of the image and drag it to the left-center edge of the slide. By grabbing the lower-left corner (or any corner, for that matter), you maintain the aspect ratio of the image and you can resize it without distortion. Again, the image should snap to the edge of the slide.

With the picture still selected, click on the “Crop” button. The circle-shaped resize handles at the image’s corners should change to crop handles. Grab the bottom-center crop handle with your mouse, and push up until it snaps onto the bottom of the slide.

A word about cropping the images: When you crop images, you may lose parts of the image that make it a pleasing composition. Feel free to drag any of the crop handles and move the photo around until you get the image looking the way you want. Just make sure when you’re finished, the image is aligned with the edges of the PowerPoint slide.

Select the image, and click the Format button under Picture Tools on the ribbon. Select the “Compress Pictures” button. In the Compress Pictures dialog, choose “Options.” Set up the Compression Options like the image below and click OK. You’ll only have to make these settings the first time. Finally, click OK on the Compress Pictures dialog. This makes the image smaller, and removes the cropped portions of the picture, leaving a slide-filling image.

Click Insert on the ribbon, and click on the text box button. Select a font, font color, and size that make the quote readable. Move to your word processing file with your quotes, highlight and copy the quotation you want to use, and then use "Paste Special, Unformatted Text" to paste the quotation into the text box.

Resize the text box as necessary, and place it in a good location on the image. For the quote here I used 24-point Arial Black in white (I have seen the quote attributed to Will Rodgers, Fred Rogers, and Wynn Catlin; I think Will is most likely but I’m amused by the incongruity of attributing it to Mr. Rogers!).

1. PowerPoint 2007 has an option under the Insert ribbon called “Photo Album.” This will bring in many photos at once, into different slides. However, it brings in all the images in 4:3 format. I haven"t found a way to change this. If you change the slide layout of the Photo Album to something else (like 16:9) PowerPoint stretches the images to fit.

2. If you insert all of your images, resize them, and crop, you can run the “Compress Pictures” process (explained in Step 3, Bringing In Images) once; it will fix all of the images on all of the slides at once.

3. Once you add your first quote, select the text box and copy it. Then, move to each slide and select “Paste.” This will place a formatted text box on each slide, in the same location from which it was copied. This is a great place to start. One caveat: When pasting your quotes from your word processing program, use “Paste Special” and choose unformatted text. That preserves your text box formatting.

4. My LCD picture frame doesn’t let you change the display time for pictures, and some of the transitions happen too quickly to allow you to read the entire quote. You can do what I did, which was to make two copies of every slide. PowerPoint is creative in its naming; the slides are called Slide1.jpg, Slide2.jpg, et cetera. I named my copies Slide1a.jpg, Slide2a.jpg. The file system sorts the original and the copy together when the files are named this way, so every quote is displayed twice with an intervening transition.

5. If you don’t have a lot slides suitable for quotes, consider visiting a site like Interface Lift, which has a wide range of images in a variety of formats for desktop wallpapers. Chances are, you’ll be able to find images in a format suitable for the native format of your LCD picture frame.

6. Finally, experiment with fonts and type colors. You can even use transparent fills in the text box to make the text stand out a bit more if your slide has a complex background.

If you"re looking for ~500-1000 display panels with the intent to buy, I would strongly suggest speaking with an account manager, sales rep, and/or applications engineer at a distributor. Such an order will likely generate enough revenue for them to give you a whole lot more than the time of day. I know the local account managers and FAE"s for a few large component distributors in my area (Future Electronics and Allied Electronics), and they are usually helpful, though not always prompt.

Looking at Future, they do seem to have a few LCDs quoted on their site, however it is certainly not a comprehensive list. If you contact a sales rep (there or anywhere) and provide them your requirements, they may come back with additional parts that their manufacturers produce that better fit your need.

Unless your volumes are going to be in the millions, let me dispel any thoughts you have of "Why not just talk to (LCD mfc) directly?". Said manufacturers will not care about you, and the premium they will charge to deal with you (if they bother at all) will be higher than what a typical distributor would, because, frankly, they do not want your direct business. Use the middlemen. They will make specifying, finding, and sourcing LCD panels vastly easier and cheaper.

To receive a quotation for a Dynamic Displays industrial LCD monitor, please provide within the quote form below, as much of the requested information as possible. This information will be used to determine the best LCD monitor replacement for your specific equipment, and to log and track your request. You will receive a response to your inquiry on the same day it was submitted.

Please complete the quote response form with as much information as you have readily available. If your LCD display is based on an existing design you can skip this step and attach any documentation that you may have, or simply list the manufacturers part number of the display that you are currently using. Either way, our engineering design team will quickly evaluate your information, help to fill any holes, and quickly get you an accurate quote for your specific display needs.

If you’re a new or existing client and wish to contact us in regards to something outside of a quote or pricing information, please visit our contact page for faster service.

The Canadian mechanical engineering student hacked the dashboard display screen in his car, so it’s now displaying funny quotes from Reddit. Specifically, it’s displaying those weird “Shower Thoughts” — the headlines from Reddit’s forum for the brilliant one-off insights that pop into your head at random moments.

“There exists a set of finite actions that, if I performed them in the correct order, would make me a millionaire in a day. I just don’t know what they are.”

“I have no programming experience other than a few Arduino projects around the house,” De Mel wrote in a blog post, “so my code is definitely not optimal.” But within one month, he’d already finished the project, and shared its Python code on GitHub. “Hopefully, this will at least give you some kind of starting point for your own project, and you will be able to see the underlying process for making this work.”

And there is something truly inspiring about a man who dares to tinker with the software in his $20,000 Hyundai, just to make its dashboard show funny quotes from Reddit.

Luckily, all the digital devices in his 2012 Hyundai Genesis Coupe were connected using a fairly common standard — the “Controller Area Network bus” (or CAN bus). So Harin grabbed one of his Arduino’s — plus a cheap SPI CANBUS circuit board — and just started doing some experiments. When he first installed his Arduino circuit board into the dashboard, the LCD began showing the time of day — every ten milliseconds — and any new messages that he sent to the screen were simply being wiped out when the system re-transmitted. But Harin had already built up a strong motivation to keep moving forward, according to a recent write-up in Make: magazine, because “I hated that stupid little blue LCD. It would just sit there staring at me brightly with the words ‘AUX’…”

So he re-routed the LCD’s input. And fortunately, Harin’s other Raspberry Pi board could accommodate a WiFi dongle. By using an iPhone for connectivity, it was now able to draw down the funny Reddit quotes. And Make: also reported that his next project may be to install a router directly into his car.

Harin’s even mounted his Nexus 7 Android tablet into his car’s dashboard and is using it to play music. In the comments on his blog, he talks about one day transmitting the “now playing” information from the tablet to the LCD. Somewhere in the mix, there’s even an SQL database. “My main script retrieves the top post from Shower Thoughts and converts the characters to their hexadecimal equivalents, adds the message ID and row identifier, and stores it in an SQL database.”

There’re two more scripts just for retrieving the quote from the database and display it on the screen, which Harin says will be building blocks for more features down the road. “Eventually, I’ll be able to screen the messages intended for the LCD on the primary [CAN bus] network and add the ones I want to keep to the SQL database while removing the ones I don’t need anymore.”

But perhaps the most inspiring part of this project is that judging by Harin’s blog posts; he only worked on it on-and-off for over a month. “I’m a full-time student with a full-time job,” Harin wrote, “so I don’t get to tinker as much as I’d like to.”

Now instead of seeing the external temperature on his display, he sees bits of mind-blowing amateur philosophy. But maybe it goes to show you that if you’re going someplace strange, your journey there can be just as unpredictable. According to his blog post, the screen was originally intended for displaying song information (title and artist) for Sirius XM.

Because of this, the Reddit quotes were originally preceded by a musical note, and one screenshot makes it look like he’d been listening to a song titled “Being a cop must be awful…”
