Adafruit 1.47 320x172 Round Rectangle Color IPS TFT Display

Don't stick to the ordinary square displays! Introduce a unique touch to your electronics with this amazing curved-edge miniature display. This new 'round rect' TFT display has a 1.47-inch diagonal, high-density 250 ppi, and 172x320 full-color pixels with IPS technology for any-angle viewing. Previously, displays of this quality were mostly MIPI interface, but this one uses SPI and comes with a user-friendly display driver, making it compatible with all microcontrollers and microcomputers. This cute little display breakout is the perfect way to add a small, colorful, and super bright display to any project. Using 4-wire SPI for communication and having its own pixel-addressable frame buffer, it can work with all kinds of microcontrollers, even those with low memory and few pins. The 1.47-inch IPS display has 172x320 16-bit full color pixels, and the color looks great up to 80 degrees off-axis in any direction. The TFT driver (ST7789) is similar to the popular ST7735, and our Arduino library supports it well. Note that the rounded corners are achieved by 'deleting' pixels. The corner pixels are still addressed in RAM but don't show up, so you can treat it like a regular rectangular display. Our breakout comes with the TFT display soldered on (using a delicate flex-circuit connector), an ultra-low-dropout 3.3V regulator, and a 3/5V level shifter, allowing you to use it with 3.3V or 5V power and logic. There's also a microSD card holder so you can easily load full color bitmaps from a FAT16/FAT32 formatted microSD card (not included). We've written a full open-source graphics library that can draw pixels, lines, rectangles, circles, text, and bitmaps, along with example code and a wiring tutorial. The code is for Arduino but can be easily ported to your favorite microcontroller. This display breakout features an 18-pin 'EYE SPI' standard FPC connector with a flip-top connector. You can use an 18-pin 0.5mm pitch FPC cable to skip the soldering. Please note that this display was originally designed for smartwatches with a glass over the screen. Without something holding the screen down, the backlight may peel away from the TFT (it's not damaging but looks bad). You can prevent this by adding a plastic or glass cover, or if using it bare, try using a bit of E6000 glue or a thin piece of tape to keep the TFT attached to the backlight.

Using this display is easy. First, connect it to your microcontroller or microcomputer. You can use the 4-wire SPI for communication. If you don't want to solder, you can use the 18-pin 'EYE SPI' standard FPC connector with the flip-top connector and an 18-pin 0.5mm pitch FPC cable. To load full color bitmaps, insert a FAT16/FAT32 formatted microSD card into the card holder. Our open-source graphics library can help you draw all kinds of shapes and text on the display. The code is written for Arduino but can be adapted to other microcontrollers. When using the display, keep in mind that it was originally designed for smartwatches with a glass cover. Without a cover, the backlight may peel away from the TFT. To prevent this, add a plastic or glass cover. If you're using it without a cover, you can use a bit of E6000 glue or a thin piece of tape on the thin side edges. As for maintenance, keep the display clean and dry. Avoid exposing it to extreme temperatures or humidity. If you have any problems, refer to our wiring tutorial and example code.
