2.4" Full-Color Capacitive Touchscreen TFT

Part Number: CFAF240320A0-024SC

This beautiful, bright, full-color display supports up to five distinct touches at a time! This touchscreen technology is referred to as a "One Glass Solution" since the touchscreen functionality is built into the glass rather than adding an additional touchscreen over the top, like traditional touchscreens. This means there is one less layer light needs to get through before hitting your eye; providing for a crisper looking display with less diffusion.

It’s sunlight-readable with 730 nits and extremely affordable, making it a great choice for any project. At 2.4" diagonal, this display is fairly compact but still has the space and resolution for just about anything you’d want to display.

The capacitive touch glass overhangs the display for easy mounting. This will make it simple for you to have a polished final product with less work. The capacitive touchscreen communicates to the controller via I2C and has an interrupt pin to notify the host of a touch. Check out our demo code for a jumping-off point for using a touchscreen in your product or project.

The display is capable of communication via 8080 parallel (8/9/16/18 bit), RGB and SPI (3- or 4-wire).

240x320 EVE 2.4" Capacitive Touchscreen LCD Display
Part Number: CFA240320E0-024SC

Are you looking for a small touch display to act as a human-machine interface for your product? This display module has it all!

The embedded EVE graphics accelerator chip simultaneously handles the display, touch, and audio functionality, lowering the development burden. The capacitive touchscreen overhangs the LCM making this display look fresh and clean when integrated into a product. The small TFT screen packs a punch. It's sunlight-readable, has a high pixel density, and displays vibrant colors.

This module comprises our 2.4" Full-Color Capacitive Touchscreen TFT attached to an EVE accelerated board. Connect with this module using a simple 30-pin FFC ZIF connection.

Key Features:

  • Graphics accelerating FT811 chip for easy graphics control
  • Capacitive Touch (5 points)
  • Sunlight Readable
  • SPI interface
  • IPS
  • Full color TFT
  • 4 x 2-56 Threaded mounting standoffs for simple mechanical design
  • 30-pin FFC ZIF Connection
EVE Graphics Accelerator Features:
  • Support multiple widgets for simplified design implementation
  • Recognize touch tags and track touch movement
  • Enhanced sketch processing
  • Anti-aliasing of primitive displayed objects for higher-quality graphics
  • Graphical effects such as alpha-blending, shadows, transitions, wipes, etc.
  • Programmable interrupt controller provides interrupts to host MCU
  • Support playback of motion-JPEG encoded AVI videos
  • Mono audio channel output with wave playback and built-in sound synthesizer
  • PWM output for display backlight dimming control

Part Change Notice #11088: Touchscreen Voltage Change

Products Affected: CFAF240320A0-024SC, CFAF240320A0-024SC-A1-1, CFAF240320A0-024SC-A1-2
Date Issued: May 26, 2021
Summary: Touchscreen Voltage Change
Description: This change is to move the resistor on the capacitive touch tail from R2 to R1 so that the typical voltage for the capacitive touch screen is 3.3V as specified in the datasheet instead of 1.8V.
Reason: The capacitive touch screen had a resistor placement that made the typical logic voltage 1.8V instead of 3.3V as specified in the datasheet.
Availability: The display will be shipping with the changes on 2021-05-28.
For reference only. For design purposes, please use the specifications in the datasheet.
