black and white lcd display free sample

LCD display in flat style black and white illustration with blank screen. The monitor is standing in a bit angling layout on side and front view position

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.

The hardware design of this carrier board is open source. Under the Datasheets & Files tab is a downloadable zip file that contains everything you need to manufacture your own boards: Gerber files, PADs source schematic and layout, and full BOM. If you have any questions, please contact our knowledgeable and friendly support staff by email, phone, or chat.

Dr Pan: Hello, Greg. VA is the abbreviation for Vertical Alignment. VA LCD is a negative and transmissive display with LED backlight. The background color is pure black. VA LCD technology is the only way for monochrome LCD screen to make the pure black background. The color of the letters is the color of LED backlight (usually white). If we want to display multi-color, some special color films will be added to the bottom of ITO glass.

Normally, if the view angle is 12 o’clock, it can be seen very clearly in 12 o’clock direction, 3 o’clock direction, 9 o’clock direction and the front side.

The maximum COM is 16, so it is not suitable for the large dot matrix and complicated displays. It is a perfect display for the pure black background high end devices.

Dr Pan: Hello, Greg. Monochrome LCD Panel can be made with TN, HTN, STN, FSTN and VA technology. It can be divided into dot matrix and segment LCD on the basis of the display mode. Depending on the types of polarizers, it can be divided into transmissive LCD, reflective LCD and transflective LCD.

Let us look at the typical structure of monochrome LCD. From top to bottom, top polarizer, top ITO glass, ITO film,liquid crystal, ITO film,bottom ITO glass and bottom polarizer.

Liquid crystal is an organic compound. It is liquid in a certain temperature range and crystal in a lower temperature. Under the influence of electric field, the liquid crystal molecules will be arranged in regular rotation of 90°, resulting in the “on/off”of light transmittance. According to this principle, we can control the image we need.

Dr Pan: Absolutely. First, it is cheaper. And usually, the colorful screens we can see are standard products, which do not need to be designed. Monochrome LCD screen is highly customized product. You can select the outer dimension, the view area, the connection type, the display mode, the view degree, the type of the polarizer and the driving mode according to your requirements.

Working OK with Picaxe 20x2 but uses pins I would like to have free for i2c. So, I am getting bigger picaxe to go with it. Used 2 rectifier diodes in series for the voltage drop to 4.2v on the backlight and two 1k ohm resisters in series for the contrast. Looks good.

Thanks loophole! I got the display working fine using this link that link that was mentioned, http://arduino.cc/en/Tutorial/LiquidCrystal, but it was dim since the backlight was not working. After reading loophole"s comment and looking at datafile I applied 4.2V pin 15 and grounded pin 16, and all was GREAT!

How bright is this? I would like to leave it on in the dark but not have it too bright such that it looks like a light source. I"m considering getting this vs. the standard black on green since it looks nicer but hoping its not too bright in the night.

The post that KHartley posted with regards to all the pin connections and using an Aduino mini pro, who then also got a reply from member 468163, that the code and everything worked.

I am using the exact components and have followed the exact pin configurations for the past 2 weeks, connecting then reconnecting, I have also tried different FTDI cables for uploading onto the Arduino pro mini. BUT have had no success, PLEASE help me as it is a basic issue I am sure but cannot find the solution, My 16*2 LCD lights up and also when I upload a program the arduino page reads that it has successfully uploaded (Done Uploading).

We"ve had customers order face plates through Ponoko for these LCDs and be pretty happy with it. Check around on the comments on other products and on the forum. You"ll probably find a lot of different examples of mounting solutions.

can this run in 8bit mode? I"m trying so hard to just wire up the 8 data lines and manually send the bits required for certain symbols. But it"s either stuck in 4bit mode, or I"m completely lost. My program is simple and I KNOW that it is sending the 1"s and 0"s down the appropriate lines but I can"t get a response at all. And I can succesfully apply the example code for liquid crystal. In class we just banged some bits into those old lcd"s and got the expected response... Is this one more advanced or something? Thanks, I really appreciate any help.

No matter what line I set the cursor at using lcd.setCursor(0,0), or lcd.setCursor(0,1), it will print everything on line 0. I"ve used the same LCD, different size before and never had this issue.

You should make the LCD"s connection pins on the bottom, like on the RGB backlit LCD"s (https://www.sparkfun.com/products/10862). I like standing them straight up and down on breadboards. If I tried that with this one, it would be upside down.

I"m having a problem with this lcd, I can"d print custom caracters, I tried the code that this site http://icontexto.com/charactercreator/ gives you when you create a custom char, tried some other examples, but nothing, I always get just two vertical bars on the second and fourth columns.

I love this little LCD! It works great. However, I"m having a wicked hard time finding hardware (i.e. self-clinching PEM stud) that I can use to mount this. The 2.5mm mounting holes are pretty small. I"m trying hard not to use glues.

I"m also having problems with contrast; I"m using a 10k pot on the contrast pin, and it takes tiny adjustments to make it work. After a minute or so running, the contrast starts to flicker, and I can"t seem to get it stable.

I"m also having trouble with LCD. I hooked up at 10kOhm pot, but when I upload the code it just gives me random pixels and characters. Is my Atmega on my Arduino Uno shot?

Like others have said, works well with liquidcrystal library and I also like to pwm the backlight with a fet on the low side. Looks really cool to have it fade out to 1 or 2% duty cycle standby mode when there has been no button presses/input in a while and then fade back in when you press a button.

Also no external resistor is needed for the backlight; just like almost all other 5v character LCDs this one has a series resistor right on the board. Mine is 130 ohms.

Works Great! Used with the Arduino and LiquidCrystal. Very clear and easy to read. I originally was setting contrast with a PWM pin to see how it worked(AKA I forgot to buy a trimpot), but it made the screen "pulse". Switched to a potentiometer I scrounged and that worked much better. Ive got the backlight hooked to +5 and its been working fine so far.

I was able to achieve much better contrast by applying a slightly negative voltage on the Vo pin (3). Minus 200 mV did the trick. I seem to remember that LCD"s used to have a negative output for just this reason. I don"t know what the rating of this pin is, so proceed with caution.

3) If you hook it to an Arduino, powering the LED backlight from a digital I/O pin will only source 40mA max. (PIC micros are even less), any more and you are overloading your output. Tie pin K (or 16) to ground, and A (or 15) will be the high side. If you design for 40mA, calculate the current limiting resistor to put between the I/O pin and pin A (or 15) of the LED backlight as follows: 5V-4.2V=0.8V and 0.8V/0.040A=20ohms however, be sure to measure the voltage across your current limiting resistor and calculate the actual current flowing to the LED just in case... don"t overload your Arduino I/O!

4) If you want to really drive it properly, you need more POWER! So grab an NPN transistor such as a 2N4401 or 2N2222 or 2N3904, and amplify your I/O. Hook a 220 to 330 ohm resistor between your I/O and the base of the NPN, hook the emitter of the NPN to ground, and the collector to the K pin (or 16) of the LED backlight. Hook a 5 to 10 ohm 1/4W resistor between the A pin (or 15) of the LED backlight and the 5V rail (make sure your 5V regulator can handle the extra 120-160mA of current you are going to be consuming)

what is the reason for the 5-10ohm resistor between the anode and the 5v? Someone mentioned that there is already a 130ohm resistor on the board in series with the backlight LED, so i can"t find a reason for it being there.

Thanks to the guy who first pointed that for that bcklight to work one needs pin 15 on +4.2V and pin 16 on ground. Without that I was getting a pretty dim job.

I made it work by using the same schematic featured in the LiquidCrystal Arduino library page, except LCD pin 6 is hooked to a digital PWM instead of a potentiometer for controlling contrast.

Pretty cool little LCD. I had some problems initially with the 4bit LCD library, but after finding that the standard LiquidCrystal library supports 4-bit data lines it worked great.

The one thing that threw me off was that the standard (not extended) datasheet mentions that the backlight (BKL) can be driven by pins 1,2 or 15,16 -- however I found that I needed to apply 4.2v to pins 15,16 before the backlight would work. Easy fix, just misleading on the datasheet.

I"m very impressed. I followed the connections from the data sheet and set them up the same way the LiquidCrystal "Hello World" example sketch calls for, and the display worked perfectly with my Arduino Duemilanove. It does take some playing with the contrast potentiometer, but I quickly found the perfect setting. The display is sharp, clear, and cool white letters on a black background.

Ordered mine a week ago and finally got around to playing with it. I used the included LiquidCrystal.h for Arduino to run this thing. Very easy to use once you get it up and running. To get the contrast working I used a 3.3Kohm resistor going to ground, looks amazing. Not quite as bright as picture but I think I"m close. 2.2Kohm is too washed out and 6.8 Kohm nothing shows up. I can"t believe how much easier this is compared to the 68HC12. Uhhh, I"m going to have nightmares for the rest of my life.

Hey I"m thinking of buying one, but I"d like to know. How bright is it, I"m thinking of using it on a buggy to show fuel, tack, and speed. So it will be vibrating around in bright sunlight. My question is, will it be legible?

Have you wired in the backlight? That tutorial doesn"t include wiring pins 15 and 16 on the lcd. I have hooked the backlight up to a pwm output so that I can turn it on and off via sketch.

I am also ahving this same problem. The LCD was great and easy to set up, but the brightness is really really poor. I installed a pot and all, but no dice.

Has anyone got this working with the LiquidCrystal or LCD4bit library? I am having quite a bit of trouble getting it to work reliably and am at the point where I am going to try and code my own library for it.

I"m also having heaps of trouble. I can sometimes get it to display text, maybe once out of every 30 attempts. And IF it decides to display anything it ends up garbling the message and locking up, not displaying the other strings in the sequence. Is this the LCD, my Arduino or the library? I tried using LCD4bit and a modified LiquidCrystal and they all yield the same, frustrating results.

Great little lcd, for basic output, debugging etc. Very easy to interface, and looks very slick! If you need a basic no frills LCD, this is a good buy.

Modular 9.3" 4K Monochrome LCD for XiP, featuring a 52 micron pixel pitch. This module plugs directly into the XiP without the need to manually attach bus wires or seat the screen. Each LCD is rated at over 3,000 hours requiring 1-2 replacements per year based on printer usage.

The idea of watching YouTube videos on a monochrome, e-paper type of display is a peculiar one. Most people are looking for a crisp, high-resolution screen with high dynamic range (HDR) to make everything on their computer look as sharp and vibrant as possible. But using a paper-like screen to read, write and work on, however, might be a much more tempting proposition.

The Boox Mira 13.3-inch E Ink monitor is one way to have the best of both worlds—a vibrant display paired with a monochrome screen that"s easy on the eyes. It"s a portable, external display that can be connected to a laptop, desktop or tablet using a USB-C or HDMI cable.

This product intrigued me on a different level than most that I try out. As someone who does a lot of typing and reading for work, I thought the 13.3-inch Mira would be a product perfect for offloading those creating and consuming tasks. It"s a screen that could be more comfortable for my eyes to stare at all day long, without completely sacrificing my MacBook Air"s color retina display.

In practice, the Mira monitor probably isn"t the perfect device for all my writing and reading needs. The product is great, but it also feels like it"s pushing the limits of the screen technology it"s relying on. But even with its many flaws, it continues to leave me with an uncharacteristically favorable impression that"s hard to shake. Being able to type on, and stare at, a screen that relieves eye strain is closer than ever, even if it hasn"t reached its final form yet.

The 13.3-inch monitor has one HDMI port and two USB-C ports. It can connect to a host of devices, including Windows or Mac computers. My unit came with a magnetic cover stand from the company to prop it up on a table. It also can be mounted to a Vesa-compatible stand for a more permanent solution.

On the right side of the monitor are the connection ports. There"s also a jog-wheel on the right to adjust the appearance settings. On the front of the screen, in the bottom right corner, is a button dedicated to refreshing the display to remove any ghosting effects. A menu button to bring up the settings is on the left side.

The monitor has a resolution of 2200 x 1650 with 207 pixels per inch. On top of everything else, it also features a capacitive touchscreen. The effectiveness of using touch will likely depend on what kind of device it"s plugged into. I had no problems with my MacBook and using touch across the system, but touch didn"t work when using a 12.9-inch iPad Pro.

Devices like Kindles and other e-readers, including the Boox Note Air 2, use E Ink screens because the technology closely mimics printed paper. Those displays, in the context of reading, are much easier on the eyes than LCD screens with bright backlighting. The paper-like technology also virtually eliminates glare and other compromises from more traditional computer monitors.

It should be noted that there"s also an accessibility component to using a monochromatic display with 16 shades of gray. Some people can"t use LCD monitors for various vision reasons, and a monitor like this could address those needs.

I was excited to use this monitor because of my line of work. In fact, I typed most of this story in Google Docs using this Boox Mira monitor. To do this and other work, I connected it to my computer using a single USB-C cable (included in the box), which gave the monitor power and data. I mostly used it to extend my built-in computer monitor to give me two screens" worth of space. I tried mirroring my screen as well to display the same thing on both, but I much preferred having one gray-scale work area and a traditional screen.

Not all computing tasks are created the same, however. To handle different kinds of application types, there are four visual presets built in to the monitor: Speed Mode, Text Mode, Image Mode and Video Mode. Each of these configurations will instantly make doing certain things more pleasing by increasing the refresh speed or changing the contrast. These modes can each be tweaked further, too, with dark color enhancement, a light color filter and refresh speed.

All, or most, settings can be changed on the screen itself, but there"s also Windows, Linux and Mac software available that can allow keyboard shortcuts to be set up. I found the Mira software to be a little rudimentary, especially in design, but it was still handy for getting the screen dialed in more quickly than using the physical buttons. I most often used a mix of Text Mode and Speed Mode.

Multiple modes are helpful because even tasks that are closely related, like writing and editing, can vary in how easy they are to accomplish using the monitor. Reading and writing are pretty effortless, but editing that writing is much harder.

Constantly moving the cursor around the screen quickly and using pinpoint accuracy to remove typos and add in punctuation felt tedious. I found it a challenge to constantly jump around to different parts of a document and tweak text with the same speed as I could using my laptop"s monitor.

The monitor itself is thin and lightweight. It"s very easy to transport, and since it does only need a single cable for power and data, it"s practical to actually take out of the house or move from room to room.

The magnetic cover it came with was fine as a temporary stand, but it is only made for one angle. I think you"ll want to have something more permanent if you plan on using it regularly at a desk. There are probably plenty of tablet stands that could work for it.

You can use the Mira monitor like any other external monitor: It will do anything, but the results can vary wildly with regard to whether it makes your work easier or harder. Browsing the web to read articles, reading and sending emails and other productivity tasks were all better experiences than I imagined they would be.

LCD (Liquid Crystal Displays) have two options or display modes.Positive mode (dark characters on a light colored background) and negative mode (lighter colored characters on a darker background).

Please see Fig.1: Yellow green STN (Super Twisted Nematic) display, the background of yellow green is lighter than dark blue characters. It is a positive mode. Fig. 2 is a blue STN display, its background of blue is darker than the white characters.It is negative mode.

Positive mode displays have the advantage of their lighter background and no backlights are needed. They normally use transflective or reflective polarizers and have lower power consumption. They can be seen with ambient light.

Negative mode displays need backlit in order to be seen. They normally use transmissive polarizers. They have better contrast and wider viewing angles in the indoor dim environment. The readability is much better than positive displays.

But under bright ambient light or even under direct sunlight, the displays will be easily washed out. In order to be seen under the bright surrounding light, the backlight brightness has to be increased to over 800 nits. The sunlight readable displays consume much power.

Of course, we can always use LED backlight in the LCD module with fewer LED chips and turn off LED backlight when not use to save power. When can also add transflective polarizer to some negative LCDs to make it sunlight readable, but the contrast will be compromised.

Positive and negative mode concept is not only limited to monochrome LCD displays (LCD panels, character LCDs, graphic LCDs etc.), it also uses for color displays, or even other display technologies.  We will categorize the displays as below,

This study did not show any significant difference in image quality between a standard 2-MP color LCD display and a medical-grade 2-MP monochrome LCD display, neither using the contrast-detail phantom nor in the visual grading study. Our findings are in accordance with several studies that have shown similar performances for color and monochrome displays in a variety of clinical tasks such as brain CT,,2 was acceptable provided that the ambient illuminance was low.

The main purpose of calibrating a monitor according to DICOM part 14 is to obtain similar image presentation on all displays. A calibration distributes the total contrast of the display equally across the entire grayscale and objects will thus be presented with the same contrast regardless of whether they are present in bright or dark parts of the image. When the task is to find known objects in an image, such as targets in a contrast-detail phantom, the window/level controls can be used to optimize image contrast. The display’s contrast characteristics becomes less important and the noise properties become more important—noise from the image detector and noise from the image display. However, this does not mean that calibrating a display is meaningless. Clinical images have little resemblance to images of a contrast-detail phantom in that pathology might be present also in the bright or dark parts of the image. A consistent display of images is even more important when, for example, a current image is compared to a previous image on another display. Any differences between the images should be caused by the imaged object and not by the displays.

The main advantage of medical-grade monochrome displays is their high luminance, which makes it easier to see the entire grayscale from black to white in an image. In a recent report,

The major drawback of color displays is their lower maximum luminance—143 cd/m2 in our study compared to 295 cd/m2 for the monochrome display. A low luminance has been stated to increase the time for diagnosis.

The tests with the contrast-detail phantom showed very small differences in image quality between the two types of displays. There was in fact a larger difference in image quality between the flat-panel detector and the storage phosphor plates (Fig. 2). It might thus be more appropriate to choose a better (more expensive) imaging system such as a flat-panel detector and use (cheaper) color displays than the opposite. Irrespective of the detector being used, there was a large interobserver variability, similar to what has been reported previously.2.

The higher ambient illuminance setting resulted in slightly poorer lesion detection on the 2-MP color display, but resulted in no difference with the 2-MP monochrome display. It is known that ambient illuminance should be low as ambient light elevates the black level of the display,

The visual grading study using clinical images showed significantly higher image quality for the 2-MP monochrome display for reproduction of pedicles and intervertebral joints; and lower for reproduction of spinous and transverse processes. Overall, there was no significant difference between the displays in the visual grading part of the study.

Free adjustment of window width and level was allowed in our study, as that is the way radiologists work in everyday practice. Windowing is easily performed by moving the computer mouse. If this type of image processing is not done, the full potential of digital imaging is not used. We consider image adjustment and manipulation to be a natural part in reading a digital image, and indeed a necessity to view all information in the image, and consequently a comparison between monochrome and color displays without the use of free adjustment of window and level was not included in this study. This is probably one reason why the 2-MP color display performed so well. All information in the image could be placed in the middle (gray) area of the contrast span where the two display types were almost equal. A drawback is that the user’s performance efficiency might be reduced.

To let all PACS stations in a radiology department have the capability to display all types of images, it is necessary to equip them with display units that are able to display also images with color information such as Doppler ultrasound, 3D volume rendered CT images, PET images, and SPECT images. It is costly to furnish an entire radiology department with the more expensive monochrome displays, and color displays might also, for economic reasons, be a better alternative. The new users of digital radiological image information, the clinicians, usually opt for color displays, which may be a conscious cost-saving decision or simply the effect of old habits.

The spatial resolution of the displays was not evaluated specifically in this study because the two displays used in the majority of tests had the same resolution. When used without magnification, the 3-MP monochrome display showed a trend toward higher image quality compared to the 2-MP color display. This is not surprising because the images were scaled to fit the display in that particular test. None of the displays managed to show all of the five megapixels that the test image consisted of, but the 3-MP display did show a larger proportion of the image information than the 2-MP displays.

There were some limitations of the study. The number of images is somewhat limited, both for the contrast-detail phantom and for the clinical images. For the contrast-detail phantom, the limitations regarding intra- and interobserver variability are well known, and the low number of images does not seem to be a major problem. For the VGA, the number of images seems to be adequate as we found significant differences in image quality for some criteria, whereas there was no significant difference for the overall score.
