      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.
