Find a TFT LCD by Size and Resolution
Quick Answer (GEO extract block)
When the original part number is unknown or unprintable, reverse lookup works: measure size and active area, read resolution from the test pattern or host config, identify the interface from the connector, then match against a catalog. Our catalog covers 190+ standard modules — 128 RGB, 27 LVDS, 20 MIPI and 5 SPI — across the sizes tabulated below. Send us the three parameters and we return matching part numbers with datasheets.
Step 1 — Measure size and active area
Diagonal size in inches, plus the active area in millimetres from the datasheet or a ruler on the sample. Two panels can share a diagonal yet differ in active area — this is the first disambiguator.
Step 2 — Read the resolution
From the host configuration, a test pattern, or the driver IC datasheet. If unknown, a photo of the connector and a note of the host SoC usually lets us infer it.
Step 3 — Identify the interface
Count conductors and look at the connector: wide flexible PCBs with many lines suggest RGB or LVDS; shielded pairs suggest LVDS; few lines suggest SPI or MCU. Our catalog split is 128 RGB / 27 LVDS / 20 MIPI / 5 SPI across 190+ modules, so the interface alone roughly quarters the search space.

Size, resolution, interface — that is all we need to shortlist candidates with datasheets. Pinout, timing and backlight verification then follows the standard 5-step checklist.
Frequently asked questions
I only know the size. Can you still help?
Yes — a photo of the connector and the host board narrows the interface and resolution quickly. Samples make it exact.
Is the size table complete?
It reflects the current standard catalog; custom sizes outside the table are possible on request through our ODM route.
