Approximately 100m of screens will be affixed to the existing fences on the Grand and Mound Stand sides of Lord's.
LED advertising screens have been a common sight in other sports - particularly football - for some years.
They have appeared once before at Lord's, during the 2009 ICC World Twenty20, and have been a feature of recent ICC global tournaments and the IPL.
Trials have also taken place in the past in domestic cricket in the UK, including in matches at Cardiff and Edgbaston.
