8x1 lcd display free sample

In this tutorial I am going to explain about the pin out, working and control systems of character lcd’s. Character lcd’s comes in many sizes for example 8×1, 8×2, 8×4, 16×1, 16×2, 20×1, 20×2, 20×4, 24×1, 24×2, 24×4, 32×1, 32×2, 40×1, 40×2 and 40×4. In these MxN dimensions, M represents number of coulombs & N represents number of rows.

All these Lcd’s available in market have 14 or 16 pins depending on the vendor/supplier. Also they all contains a same lcd controller in them which controls all their activities. Talks to external peripherals(like microcontrollers) receives data from external devices and displays them on lcd display screen. Generally every character lcd has HD44780 controller in it which controls every operation of character lcd. Some variants and competitors of HD44780 also placed step in embedded market but they are not popular for exampleAIP31066 , KS0066 , SPLC780 and ST7066 lcd controller.

In these 14 pins, 8 are data pins(FromDB-0toDB-7). Three are lcd control pinsRS(Register Select),R/W(Read-Write) &En(Enable). Two are lcd power pinsVcc(+5v)Vss(Gnd). The last pin islcd contrast pin(V0).

If lcd contains 16 pins than the extra 2 pins are LED+ and LED- pins. LED+ and LED- are for lcd’s back light, if you want to switch on the back light of lcd then use these pins other wise leave them void.

Character lcd’s which have pins arranged in two lines like headers, their pin-out is given below. Female header pin-out is shown below. Vendors for ease pre-solder the lcd pins and provide a female header for connections.

Mostly character lcds contains HD44780U lcd controller in them. HD44780 was developed by Hitachi. A single HD44780 can handle up to 80 characters. In 40×4 lcd display total characters which we can display on lcd are 40×4=160. So to control 160 characters we need two HD44780 controllers. To work with two HD44780 controllers we need an extra pin to energize the second controller.

Lcd contrast pin is same like fine tuning your television. In televisions we fine tune stations using remote but in character lcd’s we have to manually do it by varying the resistance. Varying the resistance means we control the input current to lcd. Varying resistance will fade or brighten the characters or data appearing on lcd screen.

Character Lcd’s can be interfaced in 8-bit and 4-bit mode with external controllers. In 8-bit mode all the data lines(DB0-DB7) of lcd are utilized. In 4-bit mode only four data pins of lcd are utilized (DB7-DB4). In 4-bit mode first the 8-bit ASCII value is divided in to two nibbles, first the upper nibble is send on data line and then the lower nibble. 4-bit mode is used when we want to save GPIO pins of our external device like microcontoller. An example of lcd connection with remote controller is shown in the picture below.

I prepared a good tutorial on interfacing character lcd in 8-bit and 4-bit mode with microcontrollers. Demo codes are also presented and explained in the post. Click the below button to take the tutorial.

Character LCD Displays (aka Alphanumeric) are one of the most common display technologies available and for that reason we hold inventory for samples and prototypes in our Chandler, Arizona location.

These displays have been in use for many years, and in some ways the technology has become a commodity, but it is important to select the best options to fit your design. There are many details concerning this technology, including: fluid type, operating voltage, controller/drivers and other key details that can make your design excel or under-perform.

Our team of LCD specialists can assist you in selecting the best options so that your design is able to meet your needs and at a cost that is within your budget. Call today with any questions.

These displays are used in applications such as change machines, measurement devices, and data loggers. The module has the ability to display letters, numbers and punctuation marks.

One reason for the popularity of Character LCD displays is that they are equipped with a controller/driver chip containing a built in character (or font) table.

The table holds preloaded letters, numbers, and punctuation for each language. The font table allows the designer to request any character by addressing (selecting) the number of that character. In other words, the letter capital ‘T’ may be assigned the number 31 and the “&” symbol could be assigned number 141. This eliminates the work required to create each charter from scratch and reduces the amount of time necessary to program the LCD module.

The LCD you choose for your new design sets the perceived value of your product. Think about it: The first thing your customer looks at when they are deciding whether to purchase your product, is the LCD display. If it looks good, then your product looks good.

Negative mode displays are popular for new designs since they stand out. Negative mode means the background is a darker color, like black or blue and the characters/icons/segments are a lighter color such as: White, Red or Green.

Negative mode displays must have a backlight on all the time to be readable. The challenge is that the LED backlight will draw/drain 10 times more power than the LCD without a backlight. So, if this is a battery application, it is best to stick with a positive mode.

Positive mode displays are readable without a backlight if there is enough ambient light. The LCD without a backlight will draw around 1uA. LED backlights can draw as little as 15mA up to 75mA or more depending on the number and brightness of the LEDs.

The first question to answer is ‘what size of LCD?’ The larger the display the more information that can be displayed and the larger the characters can be. We recommend you choose one of the standard sizes on this page to reduce cost and lead time. Focus Display Solutions (aka FocusLCDs) carries many of the industry standard sizes in inventory and may be able to ship the same day.

Character LCD Displays are built in standard configurations such as 8×1, 20×2 and 40×4. The two numbers identify the number of characters in each row and then the number of rows. An example of this is a 20×2 which means there are 20 characters in each row and there are two rows. This will provide you a total of 40 characters. The more characters there are on the display, the more drivers are required to drive the LCD. The controller and drivers are included with the LCD.

Note: It is possible to program the software to scroll your letters and numbers across the screen, allowing you to choose a smaller sized LCD and still display all your information.

The cost of character displays is driven more by the size of the glass, then by the number of characters. A larger 8×1 can be more expensive than a small 16×2.

It is possible to custom build a unique combination such as a 12×2 or a 16×8. This would be considered a custom LCD and would require a one-time tooling cost and possibly a higher MOQ. Go to our

Character LCD modules are available in two temperature ranges, Normal (for indoor use) and Extended (for outdoor use). The outdoor version will continue to operate down to -30C. The cost difference between normal and wide (extended) temperature range is 5% to 7% higher for the extended versions. In most cases, if cost is not critical, we recommend that you incorporate the wider temperature version.

There are three types of backlights available for a character LCD module: No backlight; LED; or EL backlight. Before introducing the various backlight options, it is helpful to cover two terms that are common for backlights: NITs and half-life.

Engineers designing a battery powered product may request a character module with no backlight since the backlight draws more than ten times (10x) the power required for the LCD alone. The goal with a battery powered product is to conserve power and extend the life-time of the battery.

If the product needs to be readable in the dark or low light conditions, then it will be necessary to attach a backlight of one type or another. The best way to conserve power is to keep the amount of time the backlight is on to a minimum. Turn off the backlight as soon as the user no longer needs it. This is a common practice in cell phones. The backlight turns off a few seconds after the number is dialed or the phone is answered. The person using the phone will continue to talk, but the display will be dark.

DC Current – LEDs are driven by DC (Direct Current), which is the same type of power required for the character LCD logic voltage. Also, batteries supply DC which makes it easy to integrate the LED backlight with a battery. EL backlights require an AC (Alternating Current) to operate. The AC signal needs to be generated by an inverter. The added inverter increases the cost of the display and produces electrical noise that can interfere with neighboring circuits.

Character LCDs that include an EL (ElectroLuminescent) backlight are not as common and their popularity is decreasing. EL backlights are AC driven which requires an inverter to be supplied by the customer or attached to the LCD. Their half-life is rated at 3K hours which makes this a poor choice for products where the backlight will be on all the time. Their MOQ (Minimum Order Quantities) have increased in the last few years. At this time there is a 500 piece MOQ.

There are some key advantages to EL backlights. They are very thin, around one to two millimeters in thickness. And they provide a very even flow of light. We carry inventory on a few EL character displays, but the majority of the character displays we sell are LED.

A character LCD is constructed by placing the nematic fluid between two layers of ITO (Indium tin oxide) glass. The function of the fluid is to either block or allow light to pass through.

A TN (Twisted Nematic) monochrome LCDs is the lowest cost option. TN does not provide a very sharp contrast and has a smaller viewing angle then STN or FSTN. A smaller viewing angle means the display is readable if you look directly at it, but if you rotate it more than 40 degrees in either direction, the characters will be difficult to read.

STN (Super Twisted Nematic) fluid is the most popular option. It provides a sharper contrast and a wider viewing angle than TN. Below is a photo of a STN 16 x2 character display.

FSTN monochrome character LCD displays are assembled by taking the STN fluid and adding a film or retardation coating to the glass. This produces a sharper contrast than STN. FSTN is more popular on higher end products such as medical applications. Below is a photo of a FSTN 16×2 monochrome LCD

There are three types of polarizers: Reflective; Transflective; and Transmissive. The correct polarizer is determined by the various lighting conditions your character LCD display will operate in.

The job of the polarizer is to allow some light to pass through and some of the light to be reflected. Depending on where your display will be operating, will decide which polarizer to choose. There is no cost difference between the three polarizers. Below is a quick summary:

The reflective polarizer is basically a mirror. It will reflect 100% of the ambient light and is ideal for displays operating in direct sunlight or in situations with very bright indoor lights.

A reflective polarizer cannot be used with a LED backlight or EL backlight since it will not allow any of the light to pass through, but it is possible to use with a LED edge-lit or side-lit display. An advantage of an edge-lit display is that it is thinner than a LED backlight, but not as thin as a display equipped with an EL backlight.

A Transflective polarizer is the most popular of the three options and works best with a display that requires the backlight to be on some of the time and off some of the time. It does not perform as well in direct sunlight as a reflective polarizer, but is sufficient in most cases.

The Transmissive polarizer is used when the backlight is on all the time. This is not the best option for battery powered products, but provides a brighter backlight. This polarizer must be used for displays that run in negative mode. Negative mode is when the characters are light colored and the background is a dark.

V Logic is the voltage used to drive an LCD and draws very little current, somewhere around 1mA or less. Character displays can be driven with a VL at 3.3V or 5V.

V LED is the voltage used to drive the LED backlight only. This can be 3.3V or 5V. LED backlights can draw up to ten times (10X) the amount of current of just the LCD alone (VLCD). If your product is a battery application, the backlight should be turned off when not in use. Or build in a sensor that only turns it on in the dark.

Is it possible to drive the LCD and the LED backlight from the same connection, but not recommended since interference from the LED backlight could affect the performance of the LCD.

A key advantage of character LCDs over multicolor technology such as TFT (Thin Film Transistor) and OLED (Organic Light Emitting Diodes) it their low thirst for current.

TFTS and OLEDs require power to generate light to be readable. In many cases, their backlight needs to be even brighter in direct sunlight. This could draw 50mA or more depending on the size and brightness of the display.

When the ambient temperature of the display drops too low, the display’s performance suffers. The colder the fluid in the display, the slower the response. At some point, the display freezes up and the characters no longer change.

As long as the temperature doesn’t drop too low, there will be no damage to the display, and it will return to normal operation when the temperature rises.

This is a much more affordable solution. A small PCB (Printed Circuit Board) is attached to the back of the LCD. The board is populated with several quarter watt resistors in series that generate heat. This option draws a great deal of power. In fact, it draws more than most LED backlights.

Believe it or not, LEDs do generate heat, but nothing close to resistors or heater film. In some cases, it is enough to give the display a little extra warmth to keep it operating when the temperature drops below its threshold.

Nothing saves heat and power like insulation. Putting your LCD into something that breaks the wind and holds in the heat, will save your batteries. Many times, a protected display will continue to operate even when the temperature drops far below the threshold. This should always be the first step taken when worrying about display functionality at low temperatures. Once your product is insulated, the heat producing options noted above can be implemented.

There are three fluid types used in character LCDs: TN, STN and FSTN. TN operates the best at colder temperatures and offers a faster response time. TN does not provide the wide viewing range found in STN and FSTN, but is sufficient for most industrial uses.

The five most common types of LCD technology are: Segment, Character, Graphic, TFT and OLED. Character and Segment are the least likely options to be discontinued. They have been around for many years and are still very popular.

The displays are made up of small squares that contain a 5x8, 7x10 or 16x16 dot matrix configurations. That means there are 5 dots across and 8 dots up for a total of 40 dots. Each dot is individuality addressed on or off to produce any letter or number.

Used to read or write the data being transferred between the LCD and the microprocessor. Tie this to ground if you only plan to write data for one-way communications.

DB 0. Most character LCDs have eight (8) data bits for faster transfer. But can operate on just four (4) data bits if you are running low on I/O (In/Outs) pins.

Positive connection of the LED backlight or side lit. The voltage could range from 5V or 3.3V. Not all character LCDs contain a LED backlight. In this case, the two pins are no connect.

Polarity is an issue with LED backlights, since they are DC (Direct Current). That means positive must connect to positive. Half of the character LCDs have pin 15 as positive and 16 as ground. The other half are reversed. If you need the polarity reversed, there is a jumper on the back of the PCB to switch polarity.

The cost to design and tool up a custom replacement LCD is much less than the cost associated with retooling a case or having to redesign the customer’s PCB to accept a different LCD. The customer may also need the exact display to repair units that are in the field.

This custom character design allows the customer to avoid any redesign cost or delays in the manufacturing of their product and to offer replacement displays for products that had been in the field for over ten years.

Character LCD displays are built in standard sizes and configurations. This makes the process of locating an equivalent LCD a simple process, but it is critical to make sure that the replacement display is a drop -in equivalent to your current display. It may not be possible to build a 100% equivalent product without some modifications.

We are able to match and replace these discontinued Liquid Crystal Displays. There may be a one-time NRE (Non-Recurring Engineering) fee required to modify the ITO glass, PCB (Printed Circuit Board) and bezel to match the dimensions and characteristics necessary for your production.

If your current LCD supplier has discontinued your display, Focus Display Solutions (aka Focus LCDs) has the ability to cross it over to an equivalent display and in many cases Fed Ex/UPS a sample to you the same day.

Note: when you begin ordering LCD displays from Focus, we will supply you with the data sheet. If you purchase the display, you should own the data sheet.

Providing us the full part number of the LCD allows us to determine not only the size of the display, but also the type of construction such as COB (Chip on Board) or COG (Chip on Glass), number of characters, backlight option, operating temperature range, background and backlight colors, viewing angle, backlight and LCD logic voltage, and in most cases the controller driver used.

With the part number, we will attempt to locate a full data sheet with enough details allowing us to quote a replacement for your discontinued display. If we cannot locate a data sheet, we will ask if your previous supplier had provided one to you.

If we are unable to locate the data sheet of your current LCD, we will request a data sheet. If possible, please forward over the data sheet or a link to the data sheet. If your LCD supplier is no longer in business or they will not provide you the data sheet, the next option is a photo of the display.

If you decided to move forward with us and order samples of your replacement display based on the estimated cost, we will require two of your discontinued samples. They do not need to be working displays, but need to be in good condition. Please note: We will not be able to return the two displays.

Note: when you begin ordering LCD displays from Focus, we will supply you with the data sheet. If you purchase the display, you should own the data sheet.

Previous examples connect the white LED backlight to power. The following example is specifically for those using an LCD with a RGB LED backlight. The only difference between the connection is the LED"s backlight on pins 15-18.

Established in 2002, Sinda Display Technology Co.,Ltd has devoted itself to the manufacturing and development of high-quality industrial display products...

A 12×2 dot matrix (AMC1202AR-B-G6NFDY) Character LCD Module display in STN Positive Gray LCD Mode, Six O’clock viewing direction, Normal Temperature Range (Operating Temp: 0°C to 50°C, Storage Temp: -20°C to 60°C), and Yellow Green LED Backlight. It has a transflective polarizer, recommended for applications that will be used both indoor and outdoor. This product is assembled Chip On board with 1/16 Duty and a Controller IC S6A0069 or equivalent. The interface type is Parallel. This is an ROHS Compliant product manufactured with ISO standards and procedures.

Text LCD displays are among the simplest. They are popular for their ease of operation and programming thanks to the HD44780 LCD controller and their analogs with the built-in set of characters including ASCII characters. Text displays consist of a matrix of dots combined into rows and columns. Formats of rows and columns are standardized by manufacturers and can be 8x1, 8x2, 10x1, 10x2, 16x1, 16x2, 16x4, 20x1, 20x2, 20x4, 24x1, 24x2. Each LCD controller is capable of operating up to 80 characters so the text LCD display with the 20x4 format is the largest. There are even larger text LCD displays such as 40x4 using several LCD controllers but they are too rare.

Initially, text LCD displays communicate with microcontrollers such as Arduino using parallel 4 or 8-bit interfaces. Some manufacturers add shift registers and port expanders to the display, making it possible to control via I2C or SPI bus. It is done for connecting convenience and reducing the number of mounting wires.

These nodes contain everything you need to start working with displays. You only have to connect your display to the microcontroller and set up proper connection parameters.

If the display communicates via an I2C bus the input parameter is the device address. Put the I2C address value of the byte type to the ADDR pin field.

If the display is controlled using a parallel interface fill in the pin values RS, EN, D4, D5, D6, D7 according to the microcontroller ports through which the display is connected.

The L input pins of the string type have indexes from 1 to 4 and correspond to the lines on your text display. The boolean value at the ACT pin is responsible for updating the display screen if the incoming string values change. Versions controlled by the I2C bus have an additional BL pin which turns on and off the display backlight.

Here is a simple example of using quick start nodes. For the example we use a 16x2 format display controlled by I2C. Connect the display to the microcontroller. Create an empty patch and put the text-lcd-i2c-16x2 quick start node onto it. The LCD screen from this example has the 38 I2C address so we put the 38h value to the ADDR pin.

Let’s print the “HELLO” word on the first line of the text display. Add a constant-string node onto the patch, fill it with the "HELLO" string value, and then link it with the L1 input pin of the quickstart node denoting the first line of the display.

A text can be entered directly into a value field of the input pin. To demonstrate it, let’s print the “WORLD” word on the second line of the display. Put the "WORLD" string value into the L2 pin of the text-lcd-i2c-16x2 quick start node.

Try a more dynamic example. Let’s display the system time, it is the time that has passed since the start of the program. To obtain the time value use the system-time node from the core library.

Remove the "WORLD" value from the L2 pin of the quickstart node and change the text inside of the constant string node to "Time: ". In XOD you can add different strings together or combine a string with a value of another data type using concat or join nodes. Put the concat node onto the patch to unite the static "Time: " text with a value received from the system-time node. To display the combined string on the first line of the display link the output pin of the concat node with the L1 pin of the quickstart node.

If the quickstart node doesn’t suit your task or the display is of a non-common format try to operate some developer nodes from the library xod-dev/text-lcd library.

Define the display you want to use to start working with it in XOD. Find out how your display communicates and place the appropriate device node from the xod-dev/text-lcd library. These nodes construct and output an lcd-device custom type value which is necessary for further work.

Use the text-lcd-parallel-device node if the display is controlled using a parallel interface. This node allows the display connection only through a 4-bit parallel interface. Here enter the pin values RS, EN, D4, D5, D6, D7. These values correspond to the microcontroller ports through which the display is connected.

Use the text-lcd-i2c-device node if the display communicates via an I2C bus. For this node, the input parameter is the device address. Enter the I2C address of your display to the ADDR pin value.

When the device is initialized, you can display text on it. To output text, use the print-at node. It fits any type of LCD device because it is generic.

The input values of the print-at nodes determine what text to display and where it should be on the display screen. Text to display is set at the VAL pin value. The ROW and POS field values set the cell coordinates on the display for the first character. That’s the place where your text begins. The LEN pin value sets the number of character cells for the text to reserve. The text can’t go beyond the boundaries you specify. It is useful, for example, when the length of your text changes during the program or you want to organize free space between several text parts. Printing is performed when the DO pin receives a pulse.

At first, let’s make a patch to print the "HELLO" text. Put the text-lcd-i2c-device node onto the patch and fill it with parameters. According to the format of the display, the number of columns is 20 and the number of rows is 4. The I2C address of the used display is 0x39 so put the 39h byte to the ADDR pin. Add the print-at node and link it with the device node. Put the HELLO to the VAL input pin.

Add one more print-at node and link with the LCD device bus. Put the "WORLD" word into the VAL field. The new text is on the same line as the previous one so set the ROW value to 1. The POS value now should be calculated. The “HELLO” word begins from the cell with index 4 and occupies 5 cells. By adding one empty cell for space and the “HELLO” word length to the previous text position you can get the POS for the new text: it is 10. Link the input DO pin of the new node with output DONE pin of the previous to execute printing sequentially.

Text displays contain a table of images for each character in their memory. These tables are used to generate letters, numbers and other symbols. Almost always a full list of all available characters can be found in the manufacturer’s datasheet. To display a specific symbol, it is necessary to transfer its hexadecimal number from the sign generator table. Use the \x## sequence to embed the character code in the string.

For example, the display that is used for this example contains five symbols which can indicate a battery capacity level. Hexadecimal codes for these symbols are 9B,9C,9D,9E, and 9F. Let’s try to display these symbols on the 3rd line of the display. Let’s change the previous example patch. Leave one print-at node and set up new printing coordinates. Put the 2 value into the ROW pin and let the POS be 7. Then, put the "\x9B\x9C\x9D\x9E\x9F" sequence of the character codes into the VAL pin…

Make your project or device more attractive and informative with a text display. Get started with quickstart nodes from the xod-dev/text-lcd library. Combine strings using concat. For non-standard cases, dive deeper into the library. Use a device node together with various action nodes, such as set-backlight and clear.

I am using Oriole 8x1 LCD Module - 08108-3SL/X. I interfaced this module with my pic18f458 and made it display "12345678", so its working.However, the back light is not ON and when I vary the contrast pin, It only affects the numbers being displayed on the LCD but not the brightness. So my question is:

1). Does this model of LCD module even have a back light feature? If so, then why isn"t it working? - It has not been mentioned in the website anywhere.

2). Does anybody know where can I find the LCD commands relevant to this module?. As there is no information regarding the LCD commands on oriole site. The image below is the datasheet for 16x2 LCD module, I used this one since there was no datasheet for the one I am using i.e. 8x1.

To those, wondering how I interfaced this LCD module and made it work without knowing where to find the commands, I am using a code snippet that was being used in my previous company. But I do not know from where they got the LCD commands relevant to this module, as its not there in the official oriole website. The below shows the schematics of LCD + PIC connections. I have used PORT D for D0 to D7 of LCD. Port C0 for RS, C1 for R/W and C2 for EN. I believe rest are understood. The schematics I have provided is generic.
