Where It Gets Used
- Handheld and portable field instruments — 2.2 mm deep, 300 KB frame buffer, and a 0.384 W backlight for battery life.
- Wall-mounted smart home and building control panels — a thin portrait module sits almost flush.
- Portable medical and laboratory devices — monitors, testers and analysers where brightness has a stated floor.
- Industrial handheld terminals and PDAs — SPI for setup, RGB for video, TE for tear-free updates.
- Test and measurement equipment — square pixels keep scales and labels true.
- Access control and intercom panels — a 3.5-inch portrait panel is a natural fit for a door station.
- Point-of-sale and handheld payment terminals.Smart home controllers and room panels — 1.65 V logic pairs with modern low-voltage MCUs.
- Factory automation sub-panels and programmers — −20 to +70 °C covers indoor industrial ambient.
- Retrofits of existing 3.5-inch 320 × 480 equipment — a widely deployed format still in service.
