Some product faces are neither rectangles nor circles — the top half of a washing-machine or oven control, the dial of an appliance that still needs a rectangular base for buttons. The half-circle (semi-circular) TFT exists for that geometry: a flat edge where the panel meets the control strip, a curved edge that follows the product's design language.
Our platform-documented model is the 3.54 inch half-circle module: 800×640 resolution on a 90.0×72.0 mm active area, FL5893DA driver, MIPI interface, and a 12-LED backlight rated at 800 cd/m² — bright because appliance faces are read across a kitchen, often through a glass door's reflections. It was documented on our Made-in-China store as a home-appliance panel, which is exactly the duty it was designed for.
Why the shape is hard, and why it exists anyway
Cutting a TFT cell into a semicircle wastes glass area compared with a rectangle, and the active area (90.0 mm wide but only 72.0 mm tall at the crown) has to be designed into the UI from the first sketch. What you get in return is a control face no rectangular competitor can copy without the same tooling commitment — for appliance brands, that distinctiveness is the point. Layout rules follow the same logic as round displays: critical data in the safe rectangle at the base, decoration towards the arc.
Getting one into your product
The module is a catalogue platform model; enclosure drawings with the exact arc geometry are available before you commit tooling. Touch integration and cover-glass printing are scoped per project via custom LCD displays. If your design is still fluid, compare the square TFT and round TFT options — one of the three geometries usually wins on cost once the bezel design is honest.
