3.5 tft lcd for arduino 2560 ili9481 supplier

This TFT 3.5 Inch LCD display support 480x320 pixel resolutions. The display uses the ILI9481 graphics controller. The module includes the 5V-3.3V power conversion circuit and no additional level conversion circuitry is required. This Module can be inserted directly into the Arduino Mega2560 Board.

Displays are one of the best ways to provide feedback to users of a particular device or project and often the bigger the display, the better. For today’s tutorial, we will look on how to use the relatively big, low cost, ILI9481 based, 3.5″ Color TFT display with Arduino.

This 3.5″ color TFT display as mentioned above, is based on the ILI9481 TFT display driver. The module offers a resolution of 480×320 pixels and comes with an SD card slot through which an SD card loaded with graphics and UI can be attached to the display. The module is also pre-soldered with pins for easy mount (like a shield) on either of the Arduino Mega and Uno, which is nice since there are not many big TFT displays that work with the Arduino Uno.

The module is compatible with either of the Arduino Uno or the Arduino Mega, so feel free to choose between them or test with both. As usual, these components can be bought via the links attached to them.

One of the good things about this module is the ease with which it can be connected to either of the Arduino Mega or Uno. For this tutorial, we will use the Arduino Uno, since the module comes as a shield with pins soldered to match the Uno’s pinout. All we need to do is snap it onto the top of the Arduino Uno as shown in the image below, thus no wiring required.

This ease of using the module mentioned above is, however, one of the few downsides of the display. If we do not use the attached SD card slot, we will be left with 6 digital and one analog pin as the module use the majority of the Arduino pins. When we use the SD card part of the display, we will be left with just 2 digital and one analog pin which at times limits the kind of project in which we can use this display. This is one of the reasons while the compatibility of this display with the Arduino Mega is such a good news, as the “Mega” offers more digital and analog pins to work with, so when you need extra pins, and size is not an issue, use the Mega.

To easily write code to use this display, we will use the GFX and TFT LCD libraries from “Adafruit” which can be downloaded here. With the library installed we can easily navigate through the examples that come with it and upload them to our setup to see the display in action. By studying these examples, one could easily learn how to use this display. However, I have compiled some of the most important functions for the display of text and graphics into an Arduino sketch for the sake of this tutorial. The complete sketch is attached in a zip file under the download section of this tutorial.

As usual, we will do a quick run through of the code and we start by including the libraries which we will use for the project, in this case, the Adafruit GFX and TFT LCD libraries.

With this done, the Void Setup() function is next. We start the function by issuing atft.reset() command to reset the LCD to default configurations. Next, we specify the type of the LCD we are using via the LCD.begin function and set the rotation of the TFT as desired. We proceed to fill the screen with different colors and display different kind of text using diverse color (via the tft.SetTextColor() function) and font size (via the tft.setTextSize() function).

The Adafruit library helps reduce the amount of work one needs to do while developing the code for this display, leaving the quality of the user interface to the limitations of the creativity and imagination of the person writing the code.

That’s it for this tutorial guys, thanks for reading. If you made some cool projects based on this or you just want to ask questions about this tutorial, feel free to reach out via the comment section below.

I just reloaded/reran the "Bodmer_UTFT_Demo_480x320" sketch - I had to rotate the due/tft 180degrees but text is printing correctly so clearly I"m having one of those moments...

With the screen orientated correctly for the demo sketch above my bitmaps are loading upside down! (they were right way up on a ILI9486 display which is what has thrown me). I can rotate those and reload but i"ll then need to also either invert the calculation of Y axis values (GFX has 0,0 in the top left corner, normal convention is bottom left).

This module is a 3.5-inch TFT LCD module with “320X480” resolution and 65K color display. It is suitable for Arduino Uno and Mega2560 development boards, and also supports SD card expansion function. It uses 8-bit parallel port communication, and the driver IC is ILI9486.

The 3.5-inch display is a ready-made shield for Arduino Uno, which can also be placed on the Arduino Mega. The pins of this shield are designed to be easily installed on the Arduino. The bad point about these modules is that they use all Arduino Uno pins.

This 262K color 320 x 480 resolutions LCD module uses a thin-film-transistor liquid crystal display (TFT LCD) to improve image qualities. With controller HX8357B included in the screen, it supports a 16-wires Data Bus Interface. This module also includes a 5V-3.3V power conversion circuit and a level conversion circuit. 100% compatible with Mega2560, it can be directly inserted into the Mega 2560 Board. Additionally, it comes with SD card socket and SPI flash circuit. Definitely a powerful module for your projects!

This display can be mounted on an Arduino Mega or Due. It has a fairly high resolution of 320*480 pixels and is also quite large with 3.2 inch LCD size.

Had this same problem with everything mirrored/backward. Not sure you"re still trying, but for any others with this issue, here"s how I addressed it..

If using the UTFT library from RinkyDink electronics, open up their initlcd.h file. In the section for Memory Access Control (lines 85-86 in version I have), change the write to:

This 3.5 inch TFT LCD is based on the ILI9481 LCD driver and gives a very sharp/nice picture quality and works amazing well with Arduino Uno and Arduino Mega Microcontrollers. Unfortunately this display is not a touchscreen display, however it makes it up with the included MicroSD Card Slot. No soldering, no wiring, no fuss just plug and play!

ili9481 lcd provide the touch interface in smartphones, which are vital for them to function. Alibaba.com stocks a stunning range of high-tech ili9481 lcd with vibrant color depictions. Truly crystal-clear displays of ili9481 lcd are available covering various brands and models such as the Samsung Galaxy Edge 2, OnePlus 7T, Samsung Galaxy C5, and many more.

ili9481 lcd are the most commonly used displays, as they produce great image quality while consuming low power. Rather than emitting light directly, they use back lights or reflectors to produce images, which allows for easy readability even under direct sunlight. ili9481 lcd are energy-efficient, and are comparatively safer to dispose of, than CRTs. ili9481 lcd are much more efficient when it comes to usage in battery-powered electronic equipment, due to their minimal power consumption.

Some other advantages of ili9481 lcd over the CRT counterparts are - sharper images, little to no heat emission, unaffected by magnetic fields, narrow frame borders, and extreme compactness, which make them very thin and light. Some types of ili9481 lcd are transmissive, reflective, and transflective displays. Transmissive displays provide better image quality in the presence of low or medium-light, while reflective displays work best in the presence of bright light. The third type of ili9481 lcd, transflective, combine the best features of both the other types and provide a well-balanced display.

Whether as an individual purchaser, supplier or wholesaler, browse for an extensive spectrum of ili9481 lcd at Alibaba.com if you don"t want to stretch a dollar yet find the best fit.

The 3.5 "display module for easy adaptability and flexibility of library had long been a reliable basis for tender color.16-bit color TFT screen and 3.5 "in size. It works as a touch screen to incorporate a capacitive sensor, which allows us to control it by touching with the finger directly on it and has a resolution of 480 × 320 pixels, relatively high for its size. Uses the ILI9481 driver.
