3.95 Inch 480x480 Square TFT LCD Module RGB-18Bit + SPI - VXT400MCSA-03

What a Square Panel Is For

• A square active area is not a novelty — it is the difference between a design that works and one that wastes half its screen. Three families of product are the reason this shape exists.
• Round displays behind a circular bezel. A 480 × 480 square is the smallest rectangle that contains a 480-pixel circle. Mount it behind a round aperture and the circle uses the full resolution, with no letterboxing and no dead corners to mask. This is how round smart-home controllers, smart speakers with displays and rotary knobs with screens get built.
• Dials, gauges and radial indicators. Analogue-style instruments — pressure, temperature, flow, speed, battery state — are drawn as arcs and needles. On a 16:9 panel the arc is squeezed into the middle third and the rest is wasted chrome. On a square panel it fills the screen.
• Square control panels. Thermostats, room controllers, access panels, lift floor indicators, smart locks and point-of-sale terminals where the enclosure is square and a wide panel would leave two empty columns.

And one thing the shape does not suit: video, wide dashboards, or controls laid out side by side. If your content is 16:9, a square panel is the wrong answer — pick a landscape module and we will point you at one

Where It Gets Used

• Round displays behind a circular bezel — the shape that makes this panel worth choosing.
• Smart home control panels and thermostats — square enclosure, square screen, no wasted columns.
• Smart knobs and rotary controllers — a square active area behind a round cap.
• Instrument dials and gauges — arcs, needles and radial indicators fill the screen instead of the middle third.
• Wearable and fitness equipment — compact, thin at 2.02 mm, and square.
• Medical monitors and portable devices — 230,400 pixels at 172 PPI for dense readings.
• Square industrial HMI — control panels that are not widescreen.
• Lift floor indicators, access panels and smart locks — small, square, wall-mounted.
• Point-of-sale and vending terminals — square UI panels and status displays.
• Embedded Linux and microcontroller projects — a 450 KB frame buffer on an RGB interface a host with a parallel output can drive directly.

General Specifications
