Product Overview
The FZ40010C40 is a 3.95″ square IPS TFT-LCD module with 480x480 resolution (1:1 aspect ratio). It uses the Sitronix ST7701S controller with a hybrid 3W SPI + RGB 18-bit interface (SPI for initialization, RGB for live image data). The 40-pin plug-in FPC tail carries backlight, RGB data bus, sync signals and optional CTP touch lines. With 400 cd/m² typical brightness, 800:1 contrast and 25,000 hr LED lifetime, it is designed for smart-home control panels, square-format wearables, and industrial HMI applications.

Frequently Asked Questions
What makes FZ40010C40 a square display?
FZ40010C40 combines a nominal 3.95-inch IPS panel with a 480 × 480 pixel, 1:1 resolution format and a published active area of 71.86 × 69.51 mm.
Which controller and interface are used?
The supplied record identifies an ST7701S controller, 3-wire SPI for initialization and an 18-bit parallel RGB bus for image data.
Can the 40-pin FPC support capacitive touch?
Pins 35–39 are allocated to optional capacitive-touch signals. Confirm whether the quoted assembly includes touch and request the matching electrical and mechanical documents.
What optical performance is published?
The source lists 400 cd/m² typical brightness, 800:1 typical contrast and 25 ms typical response time.
Which dimensions need confirmation before tooling?
Confirm module thickness, FPC geometry, connector orientation and pixel pitch against the approved drawing. The supplied record contains a pixel-pitch unit conflict, so it must not be used for tooling without verification.
