DM-TFT30-418
3.0" IPS Resistive Touch Display · 240 × 400
DM-TFT30-418 is a 3.0-inch IPS TFT display with a 240 × 400 portrait matrix and a resistive touch panel. The ILI9327 controller supports MCU, serial and RGB interface options. The 39.24 × 65.4 mm display area is contained in a 45.04 × 77.0 × 3.9 mm module, with display, backlight and four touch terminals on the module connection.

The four terminals connect the resistive touch layer to the host touch-reading circuit. Coordinate acquisition and calibration are handled by that circuit and its software. The module provides resistive terminals rather than an I²C capacitive touch controller.
Touch electrical limits
Film-side resistance
The touch specification lists 200–600 Ω for the film-side terminals.
Glass-side resistance
The glass-side terminal resistance is specified at 300–900 Ω.
Touch voltage limit
The touch panel specification lists a maximum voltage of 5 V. This limit applies to the touch layer and does not define the TFT supply voltage.

Serial control
The pin table identifies both 3-wire, 9-bit serial and 4-wire, 8-bit serial modes. WR also serves as the serial clock in DBI Type C mode.
RGB timing
The interface exposes VSYNC, HSYNC, PCLK and DE. Follow the module timing diagrams and ILI9327 register definitions when setting up RGB operation.
Add a host reading circuit for four-wire touch
The ILI9327 manages the image path. The resistive touch layer exposes four terminals for a host-side reading circuit; that circuit and the application provide coordinate acquisition and calibration.

Resistive touch selection notes
Is a capacitive touch controller included?
This model exposes four resistive touch terminals: XR, YD, XL and YU. A host-side touch-reading circuit acquires coordinates; no FT-series I²C touch controller is specified for this SKU.
Does the touch voltage limit apply to the display?
No. The 5 V maximum belongs to the resistive touch layer. The TFT pin description separately specifies VCC pins 33–34 at 2.5–3.3 V.
What defines the touch-reading circuit?
The touch specification gives film-side resistance of 200–600 Ω and glass-side resistance of 300–900 Ω. The four-terminal pin assignment and these electrical limits are the reference for the host reading circuit.
