What these numbers mean

Brightness 360 cd/m²Clearly readable under normal indoor lighting; choose a high-brightness model for direct sunlight or semi-outdoor use.
Interface 8-bit parallel / 16-bit parallel / 3-wire SPI / 4-wire SPIParallel writes are reasonably fast for mid resolutions, at the cost of more pins.
Resolution 320x480Medium density text and graphics are practical, suitable for gauges and list-style UI.
Viewing angle Full viewing angleColours hold up from above, below and both sides — useful when several people view it or the mounting angle varies.
Operating temperature -20~70 ℃Covers most indoor and general industrial environments; choose a wide-temperature model beyond that.
TouchThis model offers "Optional resistive / capacitive touch" as an option, so touch can be included or omitted per project.

Highlights

Highlights & Applications

Key features

Surface luminance 360 cd/m², clearly readable in normal indoor lighting
Full viewing angle — colours hold up from any direction, giving more freedom in mounting angle
Driven by ST7796, a well-established part with readily available documentation
Supports 8-bit parallel / 16-bit parallel / 3-wire SPI / 4-wire SPI interface, selectable to match host resources
Operating temperature -20~70 ℃, covering most indoor and general industrial environments
Available with "Optional resistive / capacitive touch" option, so touch can be decided per project

Typical applications

Industrial control panels and instrument displays, landscape or portrait
Self-service, access-control and attendance terminals
Handheld or desktop equipment needing a larger display area
Mid-to-large touch interfaces (industrial, medical, self-service)
