We offer character LCDs and graphic LCDs as modules or COG (Chip On Glass) displays in a wide array of character and pixel configuration sizes. From yellow/green, red, orange, green, blue, amber, white, and RGB backlight colors to displays without a backlight, we have the perfect LCD for your application.

Newhaven 16x2 character Liquid Crystal Display shows characters with bright orange pixels on a black background when powered on. This transmissive LCD Display requires a backlight for visibility while offering a wide operating temperature range from -20 to 70 degrees Celsius. This NHD-0216K1Z-NSO-FBW-L display has an optimal view of 6:00. This display operates at 5V supply voltage and is RoHS compliant.

Easily modify any connectors on your display to meet your application’s requirements. Our engineers are able to perform soldering for pin headers, boxed headers, right angle headers, and any other connectors your display may require.

Choose from a wide selection of interface options or talk to our experts to select the best one for your project. We can incorporate HDMI, USB, SPI, VGA and more into your display to achieve your design goals.

Bought this from Robotshop retailer. Worked right away like a charm. I even changed splash screen to display my software version. However at some point it stopped displaying text, then backlight started spontaneously switching off several seconds after powering on. I connected LCD to different device and started experimenting just sending one command at a time.

ALL 0xFE commands work just fine. I am able to switch display on/off, change between underline and blinking cursor, directly position cursor on screen and scroll screen around. 0x7C commands work too, I can control backlight and turn splash screen on/off. Reset 0x12 also works.

The only thing that does not work is actual text display. I tried all acsii characters at different cursor locations. It seems that something is going on, at least cursor jumps to 2nd line after printing 16 characters (does not move otherwise), except characters are invisible. Note that splash screen still works, with exact text I put there!

My only complaint with this product is the difficulty in mounting. Finally had to drill out the holes to accept 4-40 standoffs. The Eagle files don"t include the complete board so making a screw hole template from the PCB is impossible. Otherwise works fine with my stand alone Atmega 328P using the SerLCD.h and SoftwareSerial.h libraries.

Does anybody know how to do a hard reset on this LCD? While I was uploading my code, I left it plugged into TX, and it doesn"t work anymore. I"m realizing that it probably got spammed with commands and the configuration got messed up. Does anybody know how to reset to factory defaults?

I have the same question. I now have the 3.3v serial enabled LCD (with backpack) and want to use this one for future usage. VDD of 5V can be supplied, but will the TTL work when its getting 3.3V signals from the TX from Netduino?

I"ve put together some python code for sending serial data to these LCD screens. In particular, the code pulls my twitter status and writes it to the LCD. To work with the extra characters, I wrote functions to page the text (vertical scroll) or scroll the text (horizontal scroll). Details are available here: http://dawes.wordpress.com/2009/12/23/twitter-to-lcd/

Is it possible to wire this up in parrellel rather than use the serial function? I ran into a snag and am unable to use the serial function of this lcd? I see the pinouts on the schematic but when wired it doesn"t seem to work.

I"ve created a new splash screen for the Serial LCD, now I want to save it to the Serial LCD memory. So, exactly how do I write a "control-j" to the Serial LCD. I"ve put in the required line to transmit special character 124, but I can figure out how to format the "control-j" line of code. I"ve Googled this for about an hour and can"t find an explanation or sample code anywhere. Here"s my code...void setup() {

I"m not sure if you"re referring to comments on the website, or on your LCD screen. You can contact techsupport@ and they"ll be able to assist you further.

I have used a Labview program for this LCD. When i send character "a", the display is "0". Does anyone having a same problem. How should I troubleshoot this problem.Tq

Has anyone managed to get the PWM backlighting working with an Arduino? I"m trying variations of this and nothing works except the standard On/Off commands using 0xFE as the escape. All my attempts turn the display off but the backlight LED is on full.

Why do I get power out of the VDD port with only RX and GND hooked up? I have a 5V rail that I use to power everything on my board - and when I added this SerLCD I now have a bridge between the arduino power and my 5v line ... which I dont want. Can I add a diode to the VDD to stop reverse voltage from powering my board?

It seems like the MCLR function has been disabled through the config bits. No pullup to Vdd is installed. This makes it really irritating to work with this display. Programming an arduino with this hooked the HW serial port will screw up the display, and without the reset line you have to pull power. A simple solution would just be to wire the PICs MCLR pin to the Arduinos reset line, but this isn"t possible without the MCLR function obviously.

Quick suggestion... It"d be very helpful for some people if you guys added a note in the description pointing people to the correct 3-pin JST jumper wire to be used with these serial LCDs. Two reasons... it"s not clear that the jumper is not included, and you have 3-pin jumpers in your catalog which don"t work with this serial LCD.

I have ported LiquidCrystal library for use with the serial LCD you can look at my code here. Still working on finishing all the documentation. But putting up for now hopefully someone will find it usefull.

I"m also having the same problem after accidentally sending the control character "|" followed by "\", "-", "/" to the LCD as I was trying to animate a rotating bar to indicate a busy status.

The baud rate problem can be solved by writing at 9600, at startup, a "change baud rate" command to the target rate. At worst, the display is already at the target rate and will misinterpret the command and display garbage, at best, it will be set to the right baud rate.

Does the serial version of the display still have the parallel pins available on it? I would like to use the serial access for the most part, but I might need regular old parallel for one project.

Yes you can, but you are limited to only 8 custom characters. First define 8 bytes that will hold your custom character, one byte per line (obviously only the lower 5 bits can be used since this is a 5x8 display). Then decide which character (from 0-7) you want to set. Call this "x". Then do this pseudocode:

I"m surprised that a mechanical drawing is not included in the data sheet. It"s not too hard to measure but seems like a documentation oversight for anyone who wants to integrate the display into a case.

Having ordered this exact LCD myself, I can say that aside from the issue mentioned in my other comment, it looks exactly like the picture. No bulky backpack module, everything is on a single board. Pretty sleek, really.

Hi...noob question. how do i send data on the fly via arduino? it only has 1 connection to tx. i tried using the serial monitor to send something, but it doesnt work...im looking for something which i guess is similar to liquidCrystal->SerialDisplay example.

Nevermind, my own fault. I calculated the wrong offset to the start of the second line when I repositioned the cursor. Although the second line was displayed correctly, the offset was wrong by -32.

The data stream I tapped into once inadvertently changed the backlight level to something less than 100%, and I noticed that the dimmed display had a noticeable flicker.

I have a couple of suggestions for a future version: On the PCB layout, please add a thermal to the ground pin for the user connectors to make it easier to hand solder. Please change the firmware to make it more difficult for a random serial stream to stumble upon a configuration sequence. Maybe pick a non-printable prefix character like ESC instead of the vertical bar. Please make the brightness values more user friendly, like 1, 2, 3, etc. Maybe have an option to make the display scroll when it gets full, instead of resetting the cursor to home and overwriting. All-in-all, a fun little platform. Thanks for using a PIC on this one! I think I may try my hand at writing some new firmware for it. Cheers!

Edit: Got mine fixed. If you checked the soldering on all the terminals, check them again. I also sometimes was getting strings of garbage if I wriggled the terminals on the LCD (I suspect because I was getting a partial connection on the bad terminal). Resoldered and it is working fine now.

Wait, so I get the 3 pins for power and control, but whats with all the other pins on the sides? Can it be used to control another LCD besides the one built in?

The other pins are used if you want to control the LCD without using the serial standard. There"s some tutorials on how to do that with the arduino below. You have more control over what you can do with it, but it takes up more pins on the arduino. If you want to wire it up this way, don"t spend the money on the serial interface, they have cheaper LCD"s that allow you to do it this way, without the serial.

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.

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.

On home appliances, it is often necessary to display numbers and words to convey information, such as the current time displayed on the clock, the current temperature information on the kettle… etc. The two most commonly used displays are LED displays and LCD displays, this article will compare the advantages and disadvantages of LED displays and LCD displays, and provide a two-step quick way to quickly determine whether this product is an LCD or LED display.

LCD displays are the most common displays in daily life, from your mobile phone screen to home appliances, you can use LCD displays, but whether it is a color or black and white LCD display, in fact, the principle is the same. There are two main components within the LCD display:Backlight module

Black-and-white LCD displays are widely used in a variety of low-cost products, and the picture above is a black-and-white LCD display used in science calculator.

Advantages of monochrome LCD displays:Can show very compact information.Each display point of the calculator as shown below is very close to each other, and high-resolution text can be displayed

Power savingBlack and white LCD displays can operated without a lot of power compared to full-color LCD, when products that do not require full-color demand and need to control power consumption are often used.

CheapIf you just want to display a set of numbers or a few ICONs, the price of using a black-and-white LCD display is much cheaper than that of a full-color LCD, and it is often used in a large number of consumer products.

Disadvantages of monochrome LCD displays:Small viewing angle, not easy to use for outdoor application.Usually black and white liquid crystal display in the front view, the display is the clearest, but due to the LCD panel characteristics, as long as the side view, the clarity will be declined, outdoor will be affected by strong light, the viewing angle is not large, the clarity is not enough, LED display due to the word luminescence characteristics, there is no viewing angle problem.

Can only be used in monochromeIf you need multi-color applications, you can only upgrade to a full-color LCD display that is many times more expensive, and the LED display can simply add different colors to the LED display without significantly increasing the cost

The structure and basic introduction of the display in this article this article, compared with LCD displays, self-illumination characteristics, so that LED displays in the outdoor visibility is high, high brightness, but also no viewing angle problem. LED displays are the same as black and white LCD liquid crystals, and the display information must be designed in advance and cannot be arbitrarily transformed. The price of LED displays is between full-color LCDs and monochrome LCDs, and if properly designed, they can save the cost of achieving display performance.

This article briefly introduces the basic principles and advantages and disadvantages of two common LCD displays, and provides two steps to quickly determine whether the display in hand is an LED display, and product designers can follow these two steps to understand which display the product is used when observing the product.

Accidental Damage is any damage due to an unintentional act that is not the direct result of a manufacturing defect or failure, and is therefore not covered under the standard warranty of the LCD-Monitor. Such damage is most often the result of a drop or an impact to the LCD screen or any other part of the product which may render the device.

Non-functional :Such type of damage are only covered under an Accidental Damage service offering which is in addition to the basic warranty of the computer. Accidental Damage is not to be confused with an occasional no display or stuck pixel.
