32x128 In-Cell Touchscreen on Breakout Board

Part Number: CFAL32128A0-0171WC-E1

This product is the 1.71 inch in-cell display mounted on an adapter board.

The 1.71 inch in-cell display is an OLED with capacitive touch sensing embedded in the display itself. That makes this display impressively thin and light and eliminates the separate touch tail. Four touch zones can be recognized on the display as well as up and down swipe gestures.

Buying this display module (board and display) minimizes the work needed to have this display up and running. The required airgap is fixed in the mounting of the display to the PCB, the supply voltage from the panel is boosted from the low input voltage, and the 33-pins from the display tail are reduced and broken out to 20-pins on a 0.1" header.

This display would make a fantastic changeable button set with up to four options displayed at once.

Also check out the 0.96" in-cell display module for a similar display with different outline, and the 1.71" in-cell display full development kit.
