Through-glass message
Show a readable message through a window
Glass adds reflections, distance, and changing light. A window message needs fewer words and stronger contrast than the same text indoors.

Move the screen close to the glass, reduce the angle between the reader and display, use very high contrast, and test the message from the actual viewing position.
Messages for this situation
Control reflections before changing the font
Place the device near the glass without pressing it against an unsafe or hot surface. Tilt it until reflections move away from the main letters.
At night, a bright screen on a dark background often works well. In strong daylight, the screen may need maximum brightness and a shaded position.
Write for a barrier
Glass makes small details disappear. Keep the message to one instruction, contact method, status, or direction.
Arrows and familiar symbols can reduce the reading task, but they should support words rather than replace essential safety information.
Use window signs safely
Do not use or position a display where it blocks a driver’s view, distracts road users, or violates local rules. Prepare vehicle messages only while parked.
For an office or service window, remove personal notifications and lock access to other apps before leaving the screen visible.

QUESTIONS, ANSWERED
Through-glass message FAQ
How do I reduce glare on a window sign?
Move the display closer to the glass, change its angle, use stronger contrast, and test it from the reader’s actual position.
Should text be mirrored for a window?
No. A person looking directly through ordinary glass reads the screen normally. Mirroring is only needed in special reflection or camera workflows.
Can I use a phone sign in a car?
Only when safely parked and without blocking the driver’s view or distracting traffic. Follow local laws and venue rules.
