176x220 2" Full Color TFT LCD
Part Number: CFAF176220U-020T
This 2" TFT screen can power up to 262K colors using 8-bit 8080 parallel, or down to 4k color. This module has an integrated Sitronix ST7775R controller.The backlight on this display only requires 3.3v, making this a great choice for a screen in applications where high voltage requirements pose a problem.
Note that this display uses a solder down tail- designed to be soldered directly to corresponding pads on a PCB using a hot-bar soldering machine. This means the connection is both ultrathin and very low-cost. However, it also means this display may not be the optimal choice for hobbyists. Instead, we'd recommend a module with a ZIF tail.

The connector on the CFAF176220U-020T is a flex tail mated with a "COG" (chip on glass) display construction. This style of connector is designed to be soldered directly to corresponding pads on your PCB by using a hot-bar soldering machine. High volume contract manufacturers will be familiar with this type of construction and its assembly methods. There are hot-bar soldering machines made that are designed for prototype, rework or repair work of TAB connections.
