LMT DISPLAY / ENGINEERING GUIDES

Compare Similar TFT LCD Modules by Size, Interface and Pinout

Start with the same active area and pixel format, then compare the host interface, connector pin map and outline. Matching size, pixel count or driver IC is not evidence of drop-in compatibility.

Both use ST7789P3 and have a 23.4 × 23.4 mm active area, but their outline and pin map differ. On page 11, pin 1 is ground for LMT13010C12-V1 and the backlight anode for LMT13067C14. Do not plug one into the other’s footprint.

Both have a 30.6 × 40.8 mm active area. The 12-pin version uses SPI, while the 22-pin version uses an 8-bit MCU bus. They need different host wiring and are not substitutes on the same connector.

Replacement checklist

  1. Check module outline, active-area offset, thickness and mounting.
  2. Compare the FPC pitch, pin-1 reference, contact side and tail route.
  3. Compare each power, logic, reset and backlight pin, not just the number of contacts.
  4. Confirm initialization, timing and any separate touch assembly before ordering.
