128x128 tft display free sample

Add some dazzle to your project with this 1.45" diagonal graphic TFT LCD display module. You"ll often see this display advertised as a 1.44" Color TFT but we rounded up instead. This small display packs 128x128 full-color pixels into one square inch of active display area. It is a great choice when you need color and sharp detail while using minimal front panel space. At less than 5 grams, the display adds very little weight to handheld or wearable devices.

Thanks to the integrated Sitronix ST7735S or compatible controller, a single 3.3v source powers everything. The SPI host interface allows full read and write control of the display while using only 10 pins. The single bright white LED backlight has anode (A,+) and cathode (K, -) pins brought out on the Flexible Printed Circuit (FPC) tail. To connect, all you need is a single standard 10-conductor, 0.5 mm SMT ZIF connector.

While the SPI interface requires only a few lines to control this TFT LCD module, it is still possible to transfer data at a rate that supports 20 FPS (Frames Per Second) screen updates -- fast enough to play a full motion video.

To get started, download the datasheet and SPI sample code. And of course, Crystalfontz is always here to help you when you integrate this display into your application.

Hi guys, over the past few tutorials, we have been discussing TFT displays, how to connect and use them in Arduino projects, especially the 1.8″ Colored TFT display. In a similar way, we will look at how to use the 1.44″ TFT Display (ILI9163C) with the Arduino.

The ILI9163C based 1.44″ colored TFT Display, is a SPI protocol based display with a resolution of 128 x 128 pixels. It’s capable of displaying up to 262,000 different colors. The module can be said to be a sibling to the 1.8″ TFT display, except for the fact that it is much faster and has a better, overall cost to performance ratio when compared with the 1.8″ TFT display. Some of the features of the display are listed below;

TheTFT Display, as earlier stated, communicates with the microcontroller over SPI, thus to use it, we need to connect it to the SPI pins of the Arduino as shown in the schematics below.

Please note that the version of the display used for this tutorial is not available on fritzing which is the software used for the schematics, so follow the pin connection list below to further understand how each pin of the TFT display should be connected to the Arduino.

When connecting the display, ensure that has a voltage regulator (shown in the image below) before connecting it directly to the 5v logic level of the Arduino. This is because the display could be destroyed if the version of the display you have does not have the regulator.

In order to allow the Arduino to work with the display, we need two Arduino libraries; the sumotoy TFT ILI9163C Arduino library which can be downloaded from this link and the popular Adafruit GFX Arduino library which we have used extensively in several tutorials. Download these libraries and install them in the Arduino IDE.

For today’s tutorial, we will be using the bigtest example which is one of the example codes that comes with the sumotoy ILI9163C Arduino library to show how to use the TFT display.

The example can be opened by going to File–>Examples–>TFT_ILI9163c–>bigtest as shown in the image below. It should be noted that this will only be available after the sumotoy library has been installed.

Next, an object of the ILI9163c library named “display” was created with CS and DC parameter as inputs but due to the kind of display being used, we need to include the pin of the Arduino to which the A0 pin of the TFT display is connected which is D8.

With this done, we move to the void setup() function. Under this function, we issue the commands that initialize the display then create a time variable updated by millis, after which we issue a command to clear the screen and display some random text on it.

Some of the functions which perform actions ranging from displaying fastlines, drawing rectangles etc are then called with a delay after each function so the text or graphics stays long enough on the screen to be visible.

Up next is the void loop function. The void loop function also calls some of the same functions called under the void setup() function to display circles, rectangles etc including the testline function which is essentially used to test the screen.

With the libraries installed, open an instance of the Arduino IDE, open the examples as described initially, don’t forget to make the A0 pin (D8) correction to the code then upload to the Arduino board. You should see different kind of text and graphics being displayed on the screen. I captured the screen in action and its shown in the image below.

That’s it for this tutorial guys, what interesting thing are you going to build with this display? Let’s get the conversation started. Feel free to reach me via the comment section if you have any questions about the tutorial.

This is a graphics library for the family of small colour TFT displays based on the ST7735 and ST7789 driver chips. These are really nice displays; bright, colourful, available in a variety of useful sizes, and available at low cost from suppliers like Adafruit, AliExpress, or Banggood:

This library allows you to plot points, draw lines, draw filled rectangles, and plot text with an optional scale factor. I"ve included a demo histogram-plotting program that adjusts itself to fit each of the displays I"ve supported.

Unlike most other TFT display libraries this one doesn"t require a memory buffer, allowing it to be run on any processor down to an ATtiny85. The displays are SPI and require four pins to drive the display, leaving one pin free on an ATtiny85 to interface to another device, such as a temperature sensor. If you need more pins choose a larger chip, such as the ATtiny84; see Using the library with other AVR chips at the end of the article for information about how to convert the code for different chips.

I"ve published a library for a colour OLED display in a previous article: Colour Graphics Library. The main difference between the colour TFT displays and the colour OLED displays is that the TFT displays are not self-illuminating, and so need a backlight; they therefore have a slightly higher power consumption. However, they are exceedingly cheap, and they are available in larger sizes than the colour OLED displays.

This library will work with displays based on the ST7735 which supports a maximum display size of 132 (H) x 162 (V), or the similar ST7789 which supports a maximum display size of 240 (H) x 320 (V).

The display driver interfaces to the displays with the longer side as the vertical dimension, which is why the rectangular displays are usually listed with the longer dimension second. My library allows you to rotate the image for any desired orientation.

All the Adafruit breakout boards for these displays include level-shifting circuitry, so they will work with either 5V or 3.3V microcontroller boards. They also include an SD card socket, if that"s of interest to you. The Adafruit boards have pullups on the backlight and reset pins, so the display will work if you leave these pins unconnected.

The pullup resistor from the display"s CS pin is optional; it holds the chip select high to prevent the display from being affected by the ISP signals while programming the ATtiny85.

The different displays are catered for by six constants which specify the size of the display, the offsets relative to the area supported by the display driver, whether the display is inverted, and the rotation value; for example:

Note that on some displays you may also have to change the xoff or yoff value when rotating the display. For example, to rotate the image on the 240x240 displays by 180° use the settings:

To check or adjust the values for each display I ran this program, which draws a one-pixel border around the display area, and plots an "F" to show the orientation:

The ATtiny85 and other AVR processors supports toggling of one or more bits in a port, so provided you set all the pins to their disabled state at startup, for speed the display access routines can simply toggle the appropriate pins to enable or disable them.

The InitDisplay() routine first defines the four display pins as outputs, and takes the SCK, DC, and CS pins high (inactive). It then sends the essential configuration commands to the display.

The display memory stores 18 bits per pixel: 6 bits per colour. However, you can write to the display in three alternative modes, with 12, 16, or 18 bits per pixel. I chose the 16 bit mode, which assigns 5 bits to red, 6 bits to green, and 5 bits blue. It"s the most convenient one to work with as you simply send two bytes to define the colour of each pixel.

To clear the display the ClearDisplay() routine sends the appropriate number of zero bytes. The routine temporarily switches to 12-bit colour mode, which reduces the time to clear the display by 25%:

The library includes basic graphics routines for plotting points and drawing lines. These work on a conventional coordinate system with the origin at lower left. For example, on the 80x160 display:

My first version of PlotChar() plotted characters by calling PlotPoint() for each pixel. However, I then tried the following alternative approach which defines an area of the display using the CASET (Column Address Set) and RASET (Row Address Set) commands, and then sends a stream of the appropriate bytes to define the character. This turned out to be over three times faster!

14th January 2020: Tested the program with the Adafruit 1.3" 240x240 TFT display, and updated the program to correct a problem when rotating the image on that display.

This is a small graphics library, specifically aimed at ATtiny microcontrollers, for the variety of small colour TFT displays available at low cost from suppliers like Adafruit, AliExpress, or Banggood:

It"s an updated version of my Tiny TFT Graphics Library. This latest version of the library supports both the classic ATtiny processors, such as the ATtiny85, and the new 0-series, 1-series, and 2-series ATtiny processors, such as the ATtiny402. Like the original library it allows you to plot points, draw lines, draw filled rectangles, and plot characters and text with an optional scale factor, in 16-bit colour.

This version adds the ability to plot outline rectanges, and outline and filled circles. I"ve included demo curve-plotting and histogram-plotting programs that adjust to fit any display.

This library supports TFT displays that use an SPI interface and require four pins to drive the display. This leaves one pin free on an 8-pin chip such as the ATtiny85 or ATtiny402. If you need more pins choose a larger chip, such as the ATtiny84 or ATtiny404.

Unlike my Compact TFT Graphics Library which uses standard Arduino SPI calls, this library uses direct I/O pin manipulations. This means that you can use any assignment of pins to the four I/O lines needed by the display, and makes it about twice as fast as one using SPI calls. I"ve also added support for some additional displays, so it now supports 16 different TFT displays.

So provided you set all the pins to their disabled state at startup, the display routines can simply toggle the appropriate pins to enable or disable them.

The differences between each family of processors are handled by constants to define the pin assignments, and preprocessor macros to define the bit manipulations. If you use the circuits given below you won"t need to change anything, apart from specifying which display you"re using.

The ClearDisplay() routine has been optimised further by realising that we don"t need to keep setting the mosi bit, since to clear the display it is always zero, so the routine only needs to toggle the sck bit the appropriate number of times. I"m grateful to Thomas Scherer for suggesting this.

This library will work with displays based on the ST7735 which supports a maximum display size of 162x132, or the ST7789 and ILI9340/1 which support a maximum display size of 320x240. It includes parameters for the following colour TFT displays:

* These Adafruit displays conveniently all have the same edge-connector layout, so you can make a prototyping board or PCB that will take any of them, such as my Universal TFT Display Backpack.

Some of the AliExpress displays include a LDO 3.3V regulator, but not logic-level translation, so I recommend only interfacing them to a processor running from 3.3V.

The Adafruit displays all include an LDO 3.3V regulator and logic-level translation, so can be safely interfaced to processors powered from either 5V or 3.3V.

On the AliExpress red 160x128 display you need to connect the backlight pin to Vcc to turn it on. This doesn"t seem to be necessary with the other displays.

The library will probably support other TFT displays that use the same ST7735, ST7789, ILI9340/1 driver chips, but you may need to experiment with the parameters to get the image scaled and centered correctly.

The display needs to be connected to the microcontroller via four I/O lines: MOSI, SCK, CS, and DC. You can use any pins for these, but they should all be in the same port. You need to specify the port pin numbers of the pins you are using at the start of the Tiny TFT Graphics Library listing.

The 33kΩ pullup resistor from the display"s CS pin is optional; it is only needed on the AliExpress displays, and holds the chip select high to prevent the display from flickering while programming the ATtiny85.

The different displays are catered for by seven constants which specify the size of the display, the offsets relative to the area supported by the display driver, whether the display is inverted, the rotation value, and the order of the colours; for example:

By default the parameters give the correct orientation assuming you"re using the display with the header pins along the top, except in the case of the larger displays which have the header pins along the shorter edge, in which case the header pins are assumed to be on the left.

To check or adjust the values for each display you can run the TestChart() program, which draws a one-pixel border around the display area, and plots a red "F" to show the orientation:

The library will probably support other TFT displays that use the same driver chips, but you may need to experiment with the parameters to get the image scaled and centered correctly.

The library includes basic graphics routines for plotting points and drawing lines. These work on a conventional coordinate system with the origin at lower left. For example, on the 80x160 display:

This new library is a standalone library that contains the TFT driver as well as the graphics functions and fonts that were in the GFX library. This library has significant performance improvements when used with an UNO (or ATmega328 based Arduino) and MEGA.

Examples are included with the library, including graphics test programs. The example sketch TFT_Rainbow_one shows different ways of using the font support functions. This library now supports the "print" library so the formatting features of the "print" library can be used, for example to print to the TFT in Hexadecimal, for example:

To use the F_AS_T performance option the ILI9341 based display must be connected to an MEGA as follows:MEGA +5V to display pin 1 (VCC) and pin 8 (LED) UNO 0V (GND) to display pin 2 (GND)

TFT_ILI9341 library updated on 1st July 2015 to version 12, this latest version is attached here to step 8:Minor bug when rendering letter "T" in font 4 without background fixed

Display model TT085RAN10A is a color-active matrix thin-film transistor(TFT)liquid crystal display(LCD)that uses amorphous silicon TFT as a switching device. This TFT LCD has a 0.85 inch diagonally measured active display area with (128 horizontal by 128vertical pixels)resolution. This module is composed of a TFT LCD Panel, driver ICs, FPC and a Backlight unit.

Focus Displays offers a wide range of standard full color TFT displays. 64 million unique colors, high brightness, sharp contrast, -30C operating temperature, and fast response time are all good descriptions of a TFT display. This is why TFT technology is one of the most popular choices for a new product.

Thin Film Transistor (TFT) display technology can be seen in products such as laptop computers, cell phones, tablets, digital cameras, and many other products that require color. TFT’s are active matrix displays which offers exceptional viewing experiences especially when compared to other passive matrix technologies. The clarity on TFT displays is outstanding; and they possess a longer half-life than some types of OLEDs and range in sizes from less than an inch to over 15 inches.

CCFL’s are still available, but are becoming a legacy (obsolete) component. TFT displays equipped with a CCFL require higher MOQs (Minimum Order Quantities) than displays with LED backlights.

The majority of TFT displays contain a touch panel, or touch screen. The touch panel is a touch-sensitive transparent overlay mounted on the front of the display glass. Allowing for interaction between the user and the LCD display.

Some touch panels require an independent driver IC; which can be included in the TFT display module or placed on the customer’s Printed Circuit Board (PCB). Touch screens make use of coordinate systems to locate where the user touched the screen.

Resistive touch panels are the lowest cost option and are standard equipment on many TFT modules. They are more common on smaller TFT displays, but can still be incorporated on larger modules.

Contrast ratio, or static contrast ratio, is one way to measure the sharpness of the TFT LCD display. This ratio is the difference between the darkest black and the brightest white the display is able to produce. The higher the number on the left, the sharper the image. A typical contrast ratio for TFT may be 300:1. This number ratio means that the white is 300 times brighter than the black.

TFT LCD displays are measured in inches; this is the measurement of the diagonal distance across the glass. Common TFT sizes include: 1.77”, 2.4”, 2.8”, 3”, 4.3”, 5”, 5.7”, 5.8”, 7”, 10.2”, 12.1 and 15”.

As a general rule, the larger the size of the glass the higher the cost of the display, but there are exceptions to this rule. A larger display may be less expensive than a smaller display if the manufacture produces higher quantities of the larger displays. When selecting your color display, be sure to ask what the cost is for one size smaller and one size larger. It may be worth modifying your design requirements.

TFT resolution is the number of dots or pixels the display contains. It is measured by the number of dots along the horizontal (X axis) and the dots along the vertical (Y axis).

The higher the resolution, the more dots per square inch (DPI), the sharper the display will look. A higher resolution results in a higher cost. One reason for the increase in cost is that more driver chips are necessary to drive each segment.

Certain combinations of width and height are standardized and typically given a name and a letter representation that is descriptive of its dimensions. Popular names given to the TFT LCD displays resolution include:

Transmissive displays must have the backlight on at all times to read the display, but are not the best option in direct sunlight unless the backlight is 750 Nits or higher. A majority of TFT displays are Transmissive, but they will require more power to operate with a brighter backlight.

Transflective displays are readable with the backlight off provided there is enough ambient light. Transflective displays are more expensive than Transmissive also there may be a larger MOQ for Transflective. However, Transflective displays are the best option for direct sunlight.

Drivers update and refresh the pixels (Picture Elements) of a display. Each driver is assigned a set number of pixels. If there are more pixels than a single driver can handle, then an additional drivers are added.

A primary job of the driver is to refresh each pixel. In passive TFT displays, the pixel is refreshed and then allowed to slowly fade (aka decay) until refreshed again. The higher the refresh frequency, the sharper the displays contrast.

The controller does just what its name suggest. It controls the drivers. There is only one controller per display no matter how many drivers. A complex graphic display with several thousand pixels will contain one controller and several drivers.

The TFT display (minus touch screen/backlight) alone will contain one controller/driver combination. These are built into the display so the design engineer does not need to locate the correct hardware.

If you do not see a Thin Film Transistor (TFT) Display module that meets your specifications, or you need a replacement TFT, we can build a custom TFT displays to meet your requirements. Custom TFTs require a one-time tooling fee and may require higher MOQs.
