240x320 2.4" TFT Display with Optional Resistive Touch Screen

DT024CTFT and DT024CTFT-TS are display modules that contains a TFT display with a 320 * 240 RGB resolution. The driver used for this 2.4 inch LCD is the Ilitek ILI9341 (or compatible) and can display 262K colors. The driver is mounted on the glass and the interconnection via FPC including components to drive the display module. This LCD module size is also available with an IPS display.

Technical Support Notes

Sample Code

The provided display driver example code is designed to work with Microchip, however it is generic enough to work with other micro-controllers. The code includes display reset sequence, initialization and example PutPixel() function.

DT024CTFT vs DT024DTFT Displays

The DT024CTFT uses the same connections as DT024DTFT (please also see DT024DTFT for reference designs).

The C version has three LEDs in series at 20 mA current, while the D version has four LEDs in series with a 15 mA current.

The brightness of both versions is the same at 220 cd/m2.

If using a boost driver like the CAT4139, you will need to change the current set resistor to lower the current to 15 mA. The CAT4139 will generate the higher voltage needed automatically.

If driving the backlight of the C version display with 12 Volts and a series resistor, substituting a D version display will not work since the four LEDs need more than 12 Volts to get the same current flowing.
