Outdoor LCD displays need also to cope with sunlight. Because of the sun’s brightness and its ability to make a standard

screen unreadable, an outdoor LCD

display is often several times brighter than an indoor LCD. LCD brightness is measured in nits (a unit of luminance) and

most indoor screens have nit value of around 400; outdoor displays on the other-hand have a nit value exceeding 1200, giving

them the power to cope with even the brightest of sunshine.
