Don't be such a square - throw a curveball into your electronics with a curved-edge miniature display. Here's a new "round rect" TFT display - it's 1.47" diagonal and has high-density 250 ppi, 172x320 full-color pixels with IPS any-angle viewing. We've seen displays of this caliber used in smartwatches and small electronic devices, but they've always been MIPI interface. Finally, Adafruit found one that is SPI and has a friendly display driver, so it works with any and all microcontrollers or microcomputers!

This lovely little display breakout is the best way to add a small, colorful, and very bright display to any project. Since the display uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. Even a very small one with low memory and few pins available! The 1.47" display has 172x320 16-bit full color pixels and is an IPS display, so the color looks great up to 80 degrees off-axis in any direction. The TFT driver (ST7789) is very similar to the popular ST7735, and Adafruit's Arduino library supports it well.

Note that the way Adafruit get the rounded corners is by deleting pixels. The corner pixels are still addressed in RAM, they just don't appear, so it isn't like you have to do some special radial-pixel mapping. Treat it like a rectangular display.

Adafruit's breakout has the TFT display soldered on (it uses a delicate flex-circuit connector) as well as an ultra-low-dropout 3.3V regulator and a 3/5V level shifter so you can use it with 3.3V or 5V power and logic. They also had a little space so they placed a microSD card holder so you can easily load full color bitmaps from a FAT16/FAT32 formatted microSD card. The microSD card is not included, but you can pick one up here.

Of course, Adafruit wouldn't just leave you with a datasheet and a "good luck!" - Adafruit have written a full open-source graphics library that can draw pixels, lines, rectangles, circles, text, and bitmaps as well as example code and a wiring tutorial. The code is written for Arduino but can be easily ported to your favorite microcontroller!

This display breakout also 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 connect to all the GPIO pins, for when you want to skip the soldering.

Please note! This display is designed original for smartwatches and similar, where there's a glass over the screen. Without something gently holding the screen down, the backlight can eventually peel away from the TFT. (It's not destructive but it's unattractive) You can prevent this by, ideally, adding a plastic or glass cover/overlay. If using bare, try dabbing a touch of E6000 or similar craft glue on the thin side edges, or using a thin piece of tape to keep the front TFT attached to the backlight.
