Visibility and Display Brightness Consumer televisions are designed with your home in mind. As new consumer TVs are released, the technology used is updated based on home-use. One of the key differences between consumer and commercial TVs lies within visibility and display brightness. Display brightness is rated in terms of Nits, otherwise known as Candelas squared (cd/m2.) For comparison, one Nits is equivalent to the brightness of a single average candle.
Because they are for home use where lighting is somewhat controlled, consumer televisions usually fall in the range of 150-250 Nits. However, in brightly lit or uncontrolled lightning conditions of commercial and retail spaces, a higher brightness rating is required. Commercial displays range in brightness depending on the model. Commercial television display brightness can vary from anything between 300 to 6000 Nits for outdoor applications.
"Screen burn" or image retention is a really important consideration in digital signage applications. Digital signage will likely display the same image on screen 24/7. If displayed on a domestic television, this high single-image usage could quickly result in screen burn. Image retention, or screen burn, is the permanent discoloration of screen pixels resulting in a ghost image of the display being "burned" into the screen.
