The CTP-T350GF-04 is a 3.5-inch capacitive touch panel in G+G construction, and the only portrait panel in our range — a 48.96 x 73.44 mm view area in a true 2:3 shape, matched to 320x480 displays and to our 3.5-inch portrait TFT module. It is also the only panel whose I/O runs down to 1.8 V, so a 1.8 V-logic host can drive it without a level shifter. An FT5446 controller handles five-point touch over I2C. Built for handheld instruments, wall controllers, elevator panels and portable medical devices.
A 2:3 view area suits the things people hold and the things mounted on a wall:
Rotating a landscape panel in firmware is always an option, but it costs something: the FPC tail then exits on a long side rather than a short one, which is frequently the difference between a flex that reaches the connector and one that does not. Fitting a portrait panel avoids that entirely.
