1.46 Inch Round LCD Module 360×360 IPS QSPI
Product Description
1.46 Inch Round LCD Module — 360×360 IPS with QSPI Interface
Model: HMT146BL005-14IM-02A
A round LCD module for products that are meant to look like objects, not gadgets: smartwatches and fitness bands, smart home dials and knobs, thermostats, rotary controls and compact IoT terminals. The circular active area fills a round bezel completely, so the product reads as a watch or a dial rather than a square screen hidden behind a round cover.
At 360×360 pixels across 1.46 inches, the panel delivers roughly 349 pixels per inch. Watch hands, tick marks and small type render smoothly at close viewing distance, which is exactly where wrist-worn and hand-held products are judged.

Why this module
Thin enough for a wearable. At 1.63 mm, the module leaves room for a battery and a slim case — the constraint that usually decides whether a watch design works.
QSPI keeps the wiring simple. A quad SPI interface carries a 360×360 image over few signal lines, so the display connects cleanly to the low-pin-count MCUs and SoCs used in battery-powered wearables and dials. MIPI, RGB and SPI versions of our small displays are available where your controller calls for them.
IPS, Normally Black. Colors and contrast stay stable across the full viewing angle — important on a watch face read from any wrist position — and the normally black structure keeps the display genuinely dark when pixels are off, so a dark watch face blends into the bezel.
Stable image quality in production. High-stability liquid crystal materials and an evenly tuned backlight keep brightness uniform across the circle and consistent from batch to batch, with no flicker and reliable low-temperature start-up.
Round design, made practical
A round display is only useful if the rest of the stack is round too. We supply this module with custom round cover glass, printed borders and openings for buttons, crowns or sensors, optically bonded to the display. Optical bonding removes the air gap behind the cover, which cuts reflection outdoors, deepens contrast and strengthens the front surface.
A capacitive touch panel can be integrated in the same stack, supporting multi-touch, wet-finger operation and strong anti-interference performance. FPC length, shape and pin definition, backlight brightness and interface definition can all be adapted to your design.
Quality and reliability
Every module is produced under an IATF 16949 quality system in our own factory in Shanggao, Jiangxi, in 4,000 m² of Class 1,000 cleanroom. Each unit is 100% lighting-tested before shipment, and new designs are validated with high- and low-temperature cycling, damp-heat aging, ESD, drop and vibration testing. Our factory also holds ISO 9001, ISO 14001, ISO 45001 and IECQ QC 080000 certification, and all modules comply with RoHS, with third-party reports available on request.
Typical applications
Smartwatches and fitness bands, kids’ watches, smart home dials and rotary knobs, thermostats and HVAC controls, coffee machines and small appliances, industrial rotary instruments, and IoT terminals.
