“Transflective Film”: Testing Shows It Fails to Create
Sunlight-Readable Displays, Despite Industry Claims

AMLCD displays are increasingly popular for billboards and other outdoor applications,
and manufacturers are focusing on developing sunlight-readable AMLCDs. Previously, a

demand has increased to 1,500 nits. To reduce backlight power consumption while
improving display readability, the display industry has tried various approaches. One

bright, by using a transflective film to reflect sunlight, a standard display can output
1,500 nits without requiring any additional power.
But in reality, as testing by Insync Peripherals demonstrates,
transflective film is marketing hype:
