    What will be the mean viewing distance of red LED message board having dimension 1m/0.5m?

    this will be a variable message sign board which will display FREE and CONGESTED/ heavy traffic/Jam ahead alternatively. for a 2 lining display what will be the interlining gap so that the messages can be displayed even in the day-time. what could be the pixel density for optimum display in future?
