The Large Scale Display “Diamond Vision Mark II” and Its New Drive Method

Abstract

This paper describes a large scale display device cosisting of many segmented CRT's, and its new drive method.
The display's dynamic drive method is compared with the static drive method, it offers advantages for driving large scale devices with numerous elements.
Device simulation shows that the 2 level dynamic drive method is practical and simple.
A large and high brightness 3.84 m×2.88 m (200″) display is demonstrated, called “Diamond Vision Mark II”, composed of 3, 072 segmented CRTs each with 4×4 elements
Its maximum brightness is 1, 300 cd/m², total system power is 6 kW and total weight is 1.3 t.
