Product News – report #2 from Society for Information Displays Expo
The screen communicates with flashing backlight
It’s Friday and time for part 2 of our report on exciting new displays on show at the Society for Information Displays expo.
Transmissive/reflective panels readable in sunlight to the left in comparison with normal panels without reflective layer to the right.
Reflective displays
Some panels are designed with a reflective layer behind the liquid crystal. This increase readability in strong ambient light as the ambient light enters the display and bounces back out in the same direction as the backlight towards the user. The stronger ambient light the stronger the extra light that bounces back is which make the display readable in almost any ambient light condition. A normal panel only has the light from the lamps to create the picture and when the ambient light is stronger it is not possible to read the display.
Smart displays
Samsung also presented a new display technology which can communicate with for example a mobile phone by flashing backlight. The backlight flashes with such a high frequency that it is not visible but it can carry information. This may be used for digital signage to send information about the advertised product directly to the observer’s phone.
