What these numbers mean

Brightness 1000 cd/m²Above the usual level for this size (median about 500 cd/m²), so it stays readable in brighter ambient light.
Interface Standard RGBHigh refresh rate and good colour reproduction, suited to 4.3-inch and larger; more pins, and the host needs RGB timing output.
Resolution 480x480Medium 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 has no touch panel; choose a touch model or request customisation if you need touch.
