Integration notes for LMT34003C39
The module is MIPI-only. There is no HDMI or SPI path on this part; a host without MIPI needs a separate bridge board, which is a different assembly.
87.6 mm active area over 800 pixels gives a 109.5 µm pitch, matching the datasheet figure in both axes. Use it to check viewing distance and pixel-level legibility.
The 39-pin FPC carries MIPI lanes, power and backlight. Use the p11/p12 pin table for the exact assignment; the numbers on this page are nominal.
Luminance and weight are not published in the datasheet revision supplied. They are marked TBD rather than estimated from a similar model.
Model-specific questions
What resolution and interface does LMT34003C39 use?
800 × 800 pixels with a MIPI interface and the JD9365DA-H3 driver IC. The module is a bare panel with a 39-pin FPC; no bridge board is included.
Why is there no HDMI or driver-board option?
The datasheet covers the MIPI module only. A touch version appears in supplier imagery with a different outline (114.2 × 112.7 mm) that the datasheet does not define, so it is not offered as the same part number.
What are the enclosure dimensions?
The module outline is 94.9 × 96.95 mm and the active area is 87.6 × 87.6 mm. Use drawing page 11 for FPC position, tolerances and mounting.
What is needed for a quotation?
Specify LMT34003C39, quantity, host MIPI configuration, power rails and operating environment. Price, stock and lead time are confirmed in the quotation.
