Recognition Display Image Retention Test: Prevent Persistent School Graphics
A recognition display image retention test checks whether static graphics—school logos, navigation menus, award category headers, and hall-of-fame frames—have begun to ghost permanently onto your panel before you launch the display for daily public use. Image retention occurs when the same bright or high-contrast element occupies the same pixel region for extended periods; the affected pixels degrade faster than surrounding areas and leave a faint visible imprint even when the screen shows different content. For always-on school recognition screens, the risk is real: a lobby kiosk that runs the same branded home screen from 6 a.m. to 10 p.m. without content rotation can develop visible ghosting within weeks on consumer-grade panels and within months on commercial panels that lack proper content management settings.
