Applications will vary depending on the location of the LCD and how much ambient light is available that could cause the display to become washed out or unreadable. As a rule of thumb; notebooks and desktop LCD’s which are generally used in office light conditions are in the 200-250 nit range. For indoor use with uncontrolled or indirect sunlight it is recommended that a display of 500 – 900 nits be used. If the application is outdoors or in direct sunlight then at least 1000 nits and up should be considered.
