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.

This project is about connecting a screen from a laptop to the RIoTboard. For a full introduction, see part 1 by clicking here, it goes into more detail about this project. This part 2 covers the circuit and powering up the display.

The RIoTboard has a low-voltage differential signalling (LVDS) connector that sends data at very high speed (hundreds of MHz) in a serial form to an LCD display panel. The LCD display panel is responsible for deserializing the data back into a parallel format that the LCD display driver can understand. The advantage of this is that very few wires are required to transmit video from the RIoTboard to the LCD panel.

So, all that needs to be done is to connect up wires from the LVDS connector up to the LCD panel of choice. The LCD panel will require a certain voltage supply to operate. The backlight - often an LED backlight or a cold-cathode fluorescent lamp (CCFL) - will also require power. The particular LCD panel I used had a CCFL backlight and these require quite a high voltage (hundreds of volts) so an off-the-shelf inverter was used to generate this voltage. LED backlights require a far lower voltage.

The photo below shows the entire project, with everything taped to the back of the LCD panel to temporarily test everything out. The RIoTboard can be seen on the left (red board). Bottom-right is the main board I created which generates the required voltages to drive the LCD panel and the backlight.

There’s not much to the circuit except power supplies (on the board marked ‘Main Board’ in the photo above. The RIoTboard LVDS interface directly connects to the LCD display. The Main Board contains two main power supplies; one to drive the panel, and another for the backlight. The two voltages will vary depending on the panel chosen.

In order to have some flexibility, adjustable DC-DC converters were used so that they can be set to the desired voltages to suit different LCD panels. The DC-DC converters were off-the-shelf Texas Instruments (TI) modules, PTH04000WAH(step-down converter to drive the LCD panel) and PTN04050CAH(step-up to drive the backlight).

The LCD panel I used required 3.3V to function, and a 12-24V supply to drive the inverter to create the high voltage (HV) supply (>600V) for the cold cathode fluorescent lamp (CCFL). No inverter is needed for LED backlight panels.

The circuit for the two power supplies is shown below. The DC-DC converter U1 is used to generate a 3.3V supply to drive the LCD panel. U4 is used to step-up from 5V input up to 15V to drive the CCFL inverter which generates >600V. Different voltages can be set as can be seen in the table in the circuit diagram below (it depends on what input voltage the inverter requires), and the diagram shows the voltage set to 6V. In order to set to 15V, R12 should be 68 ohms, and R13 is not fitted.

The circuit has lots of ‘do not fit’ resistor locations that can be experimented with if it is desired to run the entire circuit and the RIoTboard from a single supply source.

The printed circuit board (PCB) that was created is shown below (the files are attached below so you can order your own from any PCB manufacturer). The board was designed to be cut into several pieces. The main board contains the two DC-DC converter modules and all associated circuitry. There is space for a variable resistor in case one is needed for dimming some displays.

The right side of the board is used to create some ‘breakout boards’. This is because it can be tricky making connections to the small connector on the LCD panel, and the mini LVDS connector on the RIoTboard. Therefore these small breakout boards are used to help with the connectivity.

There is also a small breakout board for a ‘digitizer’. This is because the LCD panel I selected has a Wacom digitizer covering the screen, for pen input. I wanted to attempt to use that with the RIoTboard too (I have not attempted it yet).

In theory many LCD panels should work. It was decided to select a slightly older panel with a reasonable resolution of 1024x768. Higher resolutions may require extremely high speed LVDS signalling and the wiring could get very critical.

More on that later, but it is probably easier to solder these wires on first (the wires are discussed next), and then solder the breakout board onto the LCD panel connector to end up with the result seen in the photograph above.

LVDS signalling is carried over pairs of wires. The communication from the RIoTboard to the LCD panel is carried over four pairs of wires. The cable is fairly critical. One option is to try Ethernet cable however in the end I decided to use the internals of a SATA cable. The photo below shows the insides of the cable with the plastic insulator stripped off. The cable has two pairs of wires. The outer screen and braid was removed, leaving just the twisted pairs with inner screen intact.

Once the connections were made, the copper ground wire was twisted around all the pairs to keep the screens all at the same voltage, and to keep a tidy bundle.

The RIoTboard uses a mini HDMI socket for LVDS signalling. A breakout board was created and soldered to a mini HDMI plug as shown here. This requires the printed circuit board thickness to be 0.8mm instead of the more usual 1.6mm.

The main board contains the two DC-DC converters mentioned earlier. The photo below shows what it looks like, assembled and taped onto the LCD panel. There is not a lot to the main board.

The particular LCD panel that I used had a CCFL backlight instead of an LED backlight. This meant that I needed an inverter to get from 15V to >600V. I purchased a cheap inverter (less than £3) from ebay (search for “5-28V 5mm Ultra-thin High Voltage Universal LCD Inverter for Laptop”). Here it is taped onto the LCD panel:

The 5V supply to the main board can now be connected up. Then, power up the RIoTboard. You should see an Android startup screen launch. Plug in a mouse, and you should be able to unlock the screen and begin using Android.

The information here will allow an LCD panel to be interfaced to the RIoTboard successfully. The next step is to create an enclosure to house it, so that the temporary wood stand can be finally discarded.

The main board also has space to connect up the digitizer portion of the LCD panel to the RIoTboard, so that pen capability can be enabled. That’s for another day too.

The full circuit diagram, parts list with order codes and plot (Gerber) files for the PCB are attached. The PCB files can be sent to any PCB manufacturer. Just specify that a 0.8mm thickness PCB is required.

Established in 1998, Winstar Display Co., Ltd. is a reliable LCD Display Module Manufacturer and LCD Panel Supplier. Winstar has development of high-quality display module products. We operate worldwide, configure, service products, and also provide logistics support to deliver products and services competitively. We provide LCM Modules including monochrome TN/STN/FSTN LCM, COG LCD, TFT LCM / TFT panels, FSC-LCD, graphic LCM, character LCD displays, OLED display modules (PMOLED), custom LCD displays, OLED and LCD panel.

Monochrome character, graphic and static displays require different input voltages. All the different LCD voltage symbols can be confusing, but believe it or not, there is a system to the madness.

The voltages VCC, VDD, VSS and VEE are used in describing voltages at various common power supply terminals. The differences between these voltages stem from their origins in the transistor circuits they were originally used for.

This LCD voltage terminology originated from the terminals of each type of transistor and their common connections in logic circuits. In other words, VCC is often applied to BJT (Bipolar Junction Transistor) collectors, VEE to BJT emitters, VDD to FET (Field-Effect Transistor) drains and VSS to FET sources. Most CMOS (Complementary metal–oxide–semiconductor) IC data sheets now use VCC and GND to designate the positive and negative supply pins.

The convention of VAB means the voltage potential between VA and VB. The convention of using 3 letters was used to show power supply and ground reference voltages as well. In some cases a processor may have both an analog and digital power supply. In this case VCCA/VCCD and VSSA/VSSD are used. Another reason for the 3 letters is in an NPN circuit with a load resister between the collector and VCC. VC would be the collector voltage. In this case VCC is the positive power supply voltage and would be higher than VC.

Pin three (3) is Vo and is the difference in voltage between VDD and VSS. This LCD voltage is adjusted to provide the sharpest contrast. The adjustment can be accomplished through a fixed resistor or a variable potentiometer. Many products have firmware that monitor the temperature and automatically adjust the contrast voltage.

In a Liquid Crystal Display (LCD), V0 is used to vary the screen brightness or contrast. Contrast, simply put is the ratio of the light areas to the dark areas in a LCD. This is usually done in a production setting with values which are optimized for most users. Temperature can have an undesirable effect on the display brightness and for this reason a varying resister or potentiometer is used to accommodate the desires of the user.

Below is a data sheet of a 16x2 Character LCD module that shows various recommended driving voltages. The LCD voltage can range from MIN (minimum) to TYP (Typical) to Max (maximum).

If the supplied LCD voltage drops too low, the display is ‘under-driven’ and will produce segments that are ‘grey’. The lower the LCD voltage falls below the acceptable threshold, the lower the contrast will be.

If the LCD is over-driven, you may see ghosting. This is where segments that should not be ‘on’ are gray. They are not as dark as the segments that should be on, but they can be seen and may cause confusion for the end user.

There are times when a customer needs to replace a display that has been discontinued or EOL (End-Of -Life) by their previous LCD supplier. The previous LCD’s pin-outs may be different than Focus’ standard, off-the-shelf display. This is not a large problem to overcome.

The third option is to pull power from pins one and two. This is the same location from which the LCD is pulling its power. Focus does not recommend this option and can modify the PCB for the customer to connect the backlight from a different location.

Many LCD Modules will require more than one internal voltage/current. This may make it necessary for the customer to supply the needed inputs. They may need to supply 3V, 5V, 9V, -12V etc.

The solution for this is to integrate a charge pump (or booster circuit) into the LCD circuitry. This solution works in most applications, but if the product will be operating in an intrinsic environment, care must be taken with layout of the circuit board.

Intrinsically-safe LCDs are Liquid Crystal Displays that are designed to operate in conditions where an arc or spark can cause an explosion. In these cases, charge pumps cannot be employed. In fact, the total capacitive value of the display needs to be kept to a minimum.

Focus Display Solutions does not build a display that is labeled ‘Intrinsically safe’ but we do design the LCD to meet the requirements of the engineer. In meeting the design engineer’s requirements, the display may need to contain two or three independent inputs. Focus can redesign the PCB and lay out the traces to allow for these additional inputs.

In this project, I will show you how to interface a 128X64 Graphical LCD with Arduino UNO. This particular LCD Module is based ST7920 LCD Controller. So, we will first see a little bit about the Graphical LCD Module and its LCD Controller ST7920.

In the previous Arduino project, I have interfaced a Nokia 5110 LCD Module with Arduino. It is also a graphical LCD which can display some basic bitmap images and graphics. But the issue with Nokia 5110 LCD Module is its resolution.

At 84 x 48 pixels, the Nokia 5110 LCD can be used for implementing a menu-based user interface. Due to its small size, the resulting menu will be limited to 3 or 4 items per page.

If we want a bigger display with more real estate to work with, then the obvious choice is to go for the bigger and better 128×64 Graphical LCD Module.

As a demonstration, after making all the hardware connections, I will display a bitmap image on the Graphical LCD Module. If you are interested in implementing a simple 16×2 Alpha-Numeric LCD with Arduino, then check out this tutorial.

At first glance, the 128×64 Graphical LCD Module seems like a bigger brother to the famous 16×2 LCD or 20×4 LCD Modules, with their similar construction and almost similar pin layout.

But there is a significant difference between those two. 16×2 or 20×4 LCDs are essentially character displays. They can only display alpha-numeric characters and some simple custom characters that are confined to a 5×8 matrix.

By using different combinations of pixels, we can basically display characters of various sizes. But the magic doesn’t end there. You can display images and graphics (small animations) as well. In a 128×64 LCD Module, there are 64 rows and 128 columns.

There are several versions of the Graphical LCD in the market. Even though the usage, application and implementations are almost identical, the main difference lies in the internal LCD Controller used to drive the dot matrix display.

Some of the commonly used LCD Controllers are KS0108, SSD1306, ST7920, SH1106, SSD1322, etc. The pin out of the final LCD Module might vary depending on the LCD Controller used. So, please verify the LCD Controller as well as the pin out before making a purchase.

The Graphical LCD Module I purchased consists of ST7920 Controller. It is manufactured by Sitronix and supports three types of bus interfaces i.e., 8-bit mode, 4-bit mode and Serial interface.

If you have used 16×2 LCD Display earlier, then you might be familiar with both 4-bit as well as 8-bit parallel interfaces. The serial interface is something new and we will explore this option in this project.

As I already mentioned, double-check with the manufacturer about the pinout of the Graphical LCD Module. The following table describes the pinout of the 128×64 LCD Module that I have.

Now that we have seen a little bit about the Graphical LCD and its controller ST7920, let us now proceed with interfacing the 128×64 Graphical LCD with Arduino. I will implement a simple circuit to demonstrate how easy it is to interface the LCD and Arduino using very few external components.

So, connect the RS, RW and E of the LCD to Digital IO pins 10, 11 and 13 of Arduino UNO. Also, in order to select the Serial Interface Mode, the PCB pin must be connected to GND.

The remaining connections are similar to a traditional 16×2 LCD. VCC and GND are connected to 5V and ground of the power supply. VO is connected to the wiper of a 10KΩ POT while the other two terminals of the POT are connected to 5V and GND respectively.

I have used the above “The Office” logo. Remember that the resolution of the 128×64 LCD is, well 128×64 pixels. So, the maximum image size should be 128×64. So, using Microsoft Paint, I have brought down the resolution of the above image to 128×64 pixels and also saved it as Monochrome Bitmap Image.

A simple project for interfacing the 128×64 Graphical LCD with Arduino is implemented here. Instead of displaying plain characters, I have displayed a bitmap image on the LCD to show its capability.

At present, we look liquid crystal displays (LCDs) everywhere; however, they didn’t develop immediately. It took so much time to develop from the development of the liquid crystal to a large number of LCD applications. In the year 1888, the first Liquid crystals were invented by Friedrich Reinitzer (Austrian botanist). When he dissolved a material like a cholesteryl benzoate, then he observed that it initially it turns into a cloudy fluid & cleared up as its temperature rose. Once it is cooled, then the fluid became blue before lastly crystallizing. So, the first experimental liquid crystal display was developed by the RCA Corporation in the year1968. After that, the manufacturers of LCD have gradually designed ingenious differences &developments on the technology by taking this display device into an incredible range. So finally, the developments in the LCD have been increased.

A liquid crystal display or LCD draws its definition from its name itself. It is a combination of two states of matter, the solid and the liquid. LCD uses a liquid crystal to produce a visible image. Liquid crystal displays are super-thin technology display screens that are generally used in laptop computer screens, TVs, cell phones, and portable video games. LCD’s technologies allow displays to be much thinner when compared to a cathode ray tube (CRT) technology.

Liquid crystal display is composed of several layers which include two polarized panel filters and electrodes. LCD technology is used for displaying the image in a notebook or some other electronic devices like mini computers. Light is projected from a lens on a layer of liquid crystal. This combination of colored light with the grayscale image of the crystal (formed as electric current flows through the crystal) forms the colored image. This image is then displayed on the screen.

An LCD is either made up of an active matrix display grid or a passive display grid. Most of the Smartphone’s with LCD technology uses active matrix display, but some of the older displays still make use of the passive display grid designs. Most of the electronic devices mainly depend on liquid crystal display technology for their display. The liquid has a unique advantage of having low power consumption than the LED or cathode ray tube.

The liquid crystal display screen works on the principle of blocking light rather than emitting light. LCDs require a backlight as they do not emit light them. We always use devices which are made up of LCD’s displays which are replacing the use of cathode ray tube.  Cathode ray tube draws more power compared to LCDs and is also heavier and bigger.

The principle behind the LCDs is that when an electrical current is applied to the liquid crystal molecule, the molecule tends to untwist. This causes the angle of light which is passing through the molecule of the polarized glass and also causes a change in the angle of the top polarizing filter. As a result, a little light is allowed to pass the polarized glass through a particular area of the LCD.

Thus that particular area will become dark compared to others. The LCD works on the principle of blocking light. While constructing the LCDs, a reflected mirror is arranged at the back. An electrode plane is made of indium-tin-oxide which is kept on top and a polarized glass with a polarizing film is also added on the bottom of the device. The complete region of the LCD has to be enclosed by a common electrode and above it should be the liquid crystal matter.

Next comes the second piece of glass with an electrode in the form of the rectangle on the bottom and, on top, another polarizing film. It must be considered that both the pieces are kept at the right angles. When there is no current, the light passes through the front of the LCD it will be reflected by the mirror and bounced back. As the electrode is connected to a battery the current from it will cause the liquid crystals between the common-plane electrode and the electrode shaped like a rectangle to untwist. Thus the light is blocked from passing through. That particular rectangular area appears blank.

An LCD TV monitor utilizes the sunglasses concept to operate its colored pixels. On the flip side of the LCD screen, there is a huge bright light that shines out in the direction of the observer.  On the front side of the display, it includes the millions of pixels, where each pixel can be made up of smaller regions known as sub-pixels. These are colored with different colors like green, blue, and red. Each pixel in the display includes a polarizing glass filter at the backside and the front side includes at 90 degrees, so the pixel looks dark normally.

Generally, every consumer doesn’t have much information regarding the different kinds of LCDs available in the market. So before selecting an LCD, they collect all the data like features, price, company, quality, specifications, service, customer reviews, etc. The truth is that promoters tend to get the benefit from the truth that most of the customers conduct extremely minimum research before purchasing any product.

In an LCD, motion blur can be an effect of how long a picture takes to switch and display on the screen. However, both of these incidents change very much among an individual LCD panel in spite of primary LCD tech. Selecting an LCD based on underlying technology must be more regarding price vs. preferred difference, viewing angles & reproduction of color than estimated blur otherwise other gaming qualities. The highest refresh rate, as well as response time, must be planned in any specifications of the panel. Another gaming tech like strobe will turn ON/OFF the backlight rapidly to decrease resolution.

The TN (Twisted Nematic) LCDs production can be done most frequently and used different kinds of displays all over the industries. These displays most frequently used by gamers as they are cheap & have quick response time as compared with other displays. The main disadvantage of these displays is that they have low quality as well as partial contrast ratios, viewing angles & reproduction of color. But, these devices are sufficient for daily operations.

IPS displays are considered to be the best LCD because they provide good image quality, higher viewing angles, vibrant color precision & difference. These displays are mostly used by graphic designers & in some other applications, LCDs need the maximum potential standards for the reproduction of image & color.

AFFS LCDs offer the best performance & a wide range of color reproduction as compared with IPS displays. The applications of AFFS are very advanced because they can reduce the distortion of color without compromising on the broad viewing angle. Usually, this display is used in highly advanced as well as professional surroundings like in the viable airplane cockpits.

The Passive-matrix type LCDs works with a simple grid so that charge can be supplied to a specific pixel on the LCD. The grid can be designed with a quiet process and it starts through two substrates which are known as glass layers. One glass layer gives columns whereas the other one gives rows that are designed by using a clear conductive material like indium-tin-oxide.

Active-matrix type LCDs mainly depends on TFT (thin-film transistors). These transistors are small switching transistors as well as capacitors which are placed within a matrix over a glass substrate. When the proper row is activated then a charge can be transmitted down the exact column so that a specific pixel can be addressed, because all of the additional rows that the column intersects are switched OFF, simply the capacitor next to the designated pixel gets a charge.

Both the displays like plasma and an LCD are similar, however, it works in a different way totally. Every pixel is a microscopic fluorescent lamp that glows through the plasma, whereas plasma is an extremely hot type of gas where the atoms are blown separately to make electrons (negatively charged) & ions (positively charged). These atoms flow very freely and generate a glow of light once they crash. The designing of the plasma screen can be done very bigger as compared with ordinary CRO (cathode-ray tube) TVs, but they are very expensive.

Thus, this is all about an overview of LCD and the structure of this from the backside to the front side can be done using backlights, sheet1, liquid crystals, sheet2 with color filters & screen. The standard liquid crystal displays use the backlights like CRFL (cold cathode fluorescent lamps). These lights are consistently arranged backside of the display to deliver reliable lighting across the panel. So the brightness level of all the pixels in the picture will have equal brightness.

I hope you have got a good knowledge of liquid crystal display. Here I leave a task for you. How is an LCD interfaced to a microcontroller? furthermore, any queries on this concept or electrical and electronic project Leave your answer in the comment section below.
