The VXT174MYKH-01 is the smallest TFT module we make and the second transflective one in our range. At 1.74 inches in a 40.77 × 36.20 × 2.40 mm footprint, it is sized for something worn or carried — and transflective means the backlight can be switched off entirely in daylight, not merely dimmed. With a 3.0 V backlight needing no boost converter and a 60 KB frame buffer needing no external RAM, three power savings stack in one display. Rated -30 to +70°C.
We also make a 5-inch transflective module, and it is worth being clear about which one you want. The larger one suits equipment mounted outdoors — panel instruments, kiosks, vehicle displays — where there is mains or a large battery and the transflective panel buys legibility. This one suits something on a person, where the cell is measured in hundreds of milliamp-hours and transflective buys run time. Same technology, different reason to specify it.
If your product is worn or carried and has to work outdoors, this is the one. If it is mounted and powered, the 5-inch one is probably a better fit and we will say so.
Why this matters more at 1.74 inches than at 5
