Where It Gets Used
-
Handheld industrial terminals and PDAs — 403 PPI keeps dense readouts and small text legible, and one flex carries display and touch.
-
Barcode and logistics handhelds — portrait FHD suits a tall data list, and DSI_TE keeps the UI tear-free.
-
Portable medical devices — handheld ultrasound, patient monitors and diagnostic instruments, where fine greyscale detail matters.
-
Handheld POS and payment terminals — a signature area and a line-item list in one tall view.
-
Smart home and building control panels — wall-mounted or handheld, normally black with an ALL viewing direction.
-
Smart doorbells and intercom panels — portrait video with a touch surface.
-
Embedded Android and Linux projects — a standard 4-lane DSI panel with I2C touch from an applications processor.
-
Test and measurement equipment — square pixels keep scales, traces and dial graphics true.
-
Wearable and body-worn equipment — 700 cd/m² with a narrow 1.78 mm side bezel.
-
Retrofits of existing 5.5-inch FHD equipment — a size and resolution that fewer suppliers cover.
