32x128 In-Cell Touchscreen OLED

Part Number: CFAL32128A0-0171B-WC

This small OLED uses In-Cell technology to include a built-in touch screen making it exceptionally thin and light for a display with capacitive touch capabilities. The display can recognize multiple touch gestures as well as touches in four touch zones and has the option of adding two out-cell external touch sensors.

With its narrow form factor, this display could make a great touch-responsive gauge, a changeable button, or a reactive indicator.

Key Features:
  • 32x128 pixel resolution
  • 1.71" diagonal dimension
  • Single 0.3mm pitch, 33 position ZIF tail (no separate tail for the capacitive touchscreen)
  • Extremely thin (2mm)
  • 4 touch zones with multiple gestures
  • 2 out-cell multi-touch options for external sensors to be connected
  • Monochrome OLED
  • SPI and I2C interface for the display and touchscreen
Are you looking for a similar but smaller in-cell touchscreen display? The .96" In-Cell Touchscreen OLED might be a better fit.

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.

  • 32x128 pixel resolution
  • 1.71" diagonal dimension
  • 20 pin tenth inch header
  • 4 touch zones with multiple gestures
  • 2 out-cell multi-touch options for external sensors to be connected
  • Monochrome OLED
  • Choice of SPI or I2C interface for the display and touchscreen
