Lord's will trial LED advertising screens at the YB40 Final on Saturday 21 September.
The trial is being implimented by ECB with the consent of MCC. The screens will be provided by specialists LED Sport.
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.
