Hi, There are some advertisement boards(moving messages), in which leds are used and they glow even in dallight.
can anyone explain that is there any special type of led that is visible in daylight
or
is there any techniqe that is used so, that Messages of advertisement board glow in understandable level in day time. ordinary leds did'nt glow like that???
IF ANYONE HAVE IDEA THEN HELP ME OUT PLEASE, THANKS.
