The 32128A is our smallest standard monochrome graphic LCD module. This LCD is ideal for remote controls and hand held products, as well as for applications that require a small, high-resolution display. The COG IC is the Sitronix ST7565V. This LCD has a FPC interface.

The ST7565V is a single-chip dot matrix LCD driver that can be connected directly to a microprocessor bus. 8-bit parallel or serial display data sent from the microprocessor is stored in the internal display data RAM and the chip generates a LCD drive signal independent of the microprocessor.

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.

Instead of displaying characters of different fonts (yes, there are libraries using which you can implement various fonts), I will straight away display an image in the form of bitmap. Before writing the code, you need to convert the bitmap image into byte arrays.

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.

The boards feature serial communications interfaces, including Universal Serial Bus (USB) on some models, which are also used for loading programs. The microcontrollers can be programmed using the C and C++ programming languages, using a standard API which is also known as the “Arduino language”. In addition to using traditional compiler toolchains, the Arduino project provides an integrated development environment (IDE) and a command line tool developed in Go. It aims to provide a low-cost and easy way for hobbyist and professionals to create devices that interact with their environment using sensors and actuators. Common examples of such devices intended for beginner hobbyists include simple robots, thermostats and motion detectors.

In order to follow the market tread, Orient Display engineers have developed several Arduino TFT LCD displays and Arduino OLED displays which are favored by hobbyists and professionals.

Although Orient Display provides many standard small size OLED, TN and IPS Arduino TFT displays, custom made solutions are provided with larger size displays or even with capacitive touch panel.

Graphic LCD displays do not offer color options such as a TFT (Thin Film Transistor) or OLED (Organic light emitting diodes). They display graphics in one color and require less power to operate.

A Graphic LCD display is just as its name implies. This LCD module is able to display images, letters and numbers that are generated through the customer’s software.

Dot Matrix displays are identified by two sets of numbers. An example of this is a 128 x 64. This display contains 128 dots along the X axis, or horizontal, and 64 dots along the Y axis or Vertical. Each of these dots, sometimes referred to as a pixel, can be turned ON and OFF independently of each other. The customer makes use of software to tell each dot when to turn ON and OFF. This is similar to the old ‘light bright’ toy.

Any application that needs to display more than just letters and numbers can make use of a Graphic LCD display. A crane manufacture provides a display that shows the position of the crane’s boom as it moves from ground level to full extension.

Gas pumps making use of a Graphic LCD Display are able to display more than just gallons or total dollars. They can now display advertising and weather reports and you can enter your zip code, select payment type and even obtain a receipt through the touch screen interface attached to the glass of the display.

The three types of fluid that are available for use in a Graphic LCD Display is FSTN, STN and TN. Though TN (Twisted nematic display) and STN (Super-twisted nematic display) are rarely used on Graphic LCD Display. The primary reason is that FSTN (Film compensated Super Twisted Nematic) offers a wider viewing angle and a shaper contrast. It is possible to substitute STN or even TN for FSTN to save cost, but the lower performance rarely justifies the cost savings.

The backlight is what sits behind the glass to light up the display when ambient conditions make it difficult to read. The most common type of backlight is a LED (light-emitting diode). LED’s offer a very long life time and does not produce electrical interference that is common with CCFL and EL backlights.

If the size of the display is small enough, the LCD display manufacturer may make use of a side-lit instead of a backlight. Side lit displays offer the advantage of being thinner. Side lit backlights do not work well for a large size glass since it will create hot spots (bright and dim areas) on the display.

CCFL is an excellent backlight for large size displays. It provides a more even light flow and is thinner than LED’s. The drawback is the availability of CCFL backlights. They are pretty much non-existent for monochrome Graphic LCD Displays. You may be able to locate a supplier, but the MOQ (Minimum Order Quantity) of this backlight is in the thousands. CCFL’s also produce electrical noise that may interfere with adjacent circuits.

LCD controller driver chips (C/D) or IC’s are the small chips on the back of the LCD display. The job of the LCD controller driver is to convert the customer’s software, or firmware, into images on the display screen.

It is common for LCD controller drivers to be discontinued over time. This means that your LCD Display manufacturer will recommend an ‘equivalent’ controller. As a general rule we find that equivalent controller drivers are compatible with the old C/D an estimated 95% of the time. If you find that you’re current controller driver is about to become ‘end of life’, it would be wise to order samples of your display with a new C/D that is compatible and not being phased out.

Graphic LCD Displays normally refer to monochrome graphics LCD displays or dot matrix LCD displays. Although color TFT (Thin Film Transistor) and OLED (Organic Light Emitting Diodes) displays to meet all the definitions of graphic LCD displays and can also be categorized as graphic LCD displays, monochrome graphics LCD displays have been in the market much earlier than color TFT displays and they become the legacy type of display. That is the reason that Graphic LCD displays only refer to monochrome, not the full color.

Compared with Character LCD Displays which can only display digits or alphanumeric, graphic LCD displays can display digits, alphanumeric, and graphics. They played very important roles in the early stages of LCD display history.

Graphic LCD displays are identified by the number of pixels in vertical and horizontal directions. For example, 128 x 64 dot matrix graphic display has 128 dots/pixels along the X axis, or horizontal, and 64 dots/pixels along the Y-axis or Vertical. Each of these dots sometimes referred to as a pixel, can be turned ON and OFF independently of each other. The customer makes use of software to tell each dot when to turn ON and OFF. The early engineering work has to light/map pixel by pixel, which is very tedious work. Thanks to the LCD controller advancement, Some Orient Display graphic LCD products have many images in the memory already which greatly helps engineers to reduce the workload and make the products much faster to the market. Please check with our engineers for details.

Orient Display provides dot matrix formats of 122×32, 128×64, 128×128, 160×32, 160×64, 160×160, 192×48, 192×64,202×32, 240×64, 240×160, 240×128, 282×128, 320×240 etc.

There are many options for graphic LCD displays, all of them derived from STN (Super-Twisted Nematic Display). TN (Twisted Nematic Display) or HTN (High-performance TN) displays are rarely used in graphic LCD displays because of their poor contrast and narrow viewing angles.

LCD itself can’t emit light. In order to be observed under the dim light, the backlight has to be used. Back to 10 years ago, Backlight can be LED (Light Emitting Diode), CCFL (Cold Cathode Fluorescent Lamps) or EL (Electroluminescent) backlight. Thanks to the development of LED technology, especially the breakthrough of the blue and white LED technologies, LED backlight dominates the market. LED backlight can be made either bottom lit and side lit with various colors For more information, please refer to Orient DisplayJazz Graphic LCD Display and Backlights.

The LCD controller is a small microprocessor that converts the customer’s software code (aka firmware) to information that the LCD can understand. LCD Drivers control the complex AC voltage requirements for the LCDs and they need a LCD controller to keep refreshing the individual pixel information to their drive circuitry. These ICs will typically be integrated into the LCD Modules either by COG (Chip on Glass) or COB (Chip on Board) technologies.

Sitronix is the world’s biggest graphic LCD controller manufacturers. The headache for most engineers is that LCD controllers can EOL (End of Life) a lot. Please make sure to discuss with Orient Display engineers for the most updated information to keep 5-10 years supply life.
