Screen Brightness, Image Retention and Running Displays All Day

A screen in a lobby or corridor runs far longer each day than a TV at home. A few simple settings keep it readable, comfortable to look at and healthy for years.

Brightness

Match the space

• Sunny lobbies need higher brightness so content isn't washed out by daylight.
• Interior corridors and elevator landings need much less. A screen that's too bright in a dim hallway is uncomfortable, especially at night.

Use scheduling or sensors

Many commercial displays can adjust brightness on a schedule or with an ambient light sensor: brighter in the day, dimmer in the evening.

Image retention and burn-in

When the same image stays on a screen for long periods, some display technologies can show a faint ghost of it later.

• LCD displays can show temporary image retention, which usually fades.
• OLED displays are more susceptible to permanent burn-in, which is one reason LCD is usually preferred for signage that shows static elements all day.

How to avoid it

• Rotate content so no single slide stays up for hours
• Avoid permanent static elements like a fixed logo or clock in the same spot; move or vary them
• Use signage templates designed for long runs, with backgrounds that aren't pure static high-contrast blocks
• Schedule off-hours so the screen rests

Quiet hours

Does a corridor screen need to be on at 3 AM? Usually not. Scheduling screens to turn off or dim overnight:

• Saves electricity
• Extends display and backlight life
• Reduces light in corridors at night

The lobby screen near the concierge desk might stay on longer; floor corridor screens can usually turn off.

Heat

Displays and players last longer when they run cool. Recessed installations need an air gap and sometimes ventilation. A display that's always hot to the touch is ageing faster than it should. See flush mount vs surface mount.

Lock the settings

Use the display's lock function so passers-by can't change inputs, brightness or power from buttons or a stray remote.

Monitor it

A managed service that checks each screen regularly will catch dimming backlights, stuck content or a display that didn't wake up this morning.
