Description
Adafruit 1.9" 320x170 Color IPS TFT Display LCD Driver unit
Adafruit 1.9" 320x170 Color IPS TFT display has 320x170 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 (Sitronix ST7789) is very similar to the popular ST7735.
Details:
ST7789
