INTRODUCTION

This publication is comprised of two parts: general information
on phosphors, and registered data on individual screens. It is
intended to serve two groups of people: phosphor and CRT
manufacturers interested in registering new phosphors and end users
of CRT's interested in determining what screen type is most
suitable for an application. In addition to the "hard copy"
presentation of the general information and the registered data,
the data is also presented on computer diskette for handy reference
use. The following information pertains to the use of the
diskette.

1. FILE NAME WWPHO123.WKl

2. The data is formatted using MS DOS %o be used with IBM
Compatible type personal computers.

3. Any program able to read .WK1 programs should accept this
format. However, this file was written using Lotus 123.

End users should be warned that checking published data on a
phosphor is only the first step in evaluating a phosphor for
ergonomic criterion. A screen type must be tested by a variety of
viewers under conditions similar to what the end user will see to
ensure there are no ergonomic problems, Flicker is the most
intractable problem associated with CRT screens. While published
persistence data will serve as a guide to flicker, persistence is
not the only factor, nor even necessarily the primary one, in
determining whether flicker will be perceived.

Test methods in publication TEP-105 should be used whenever
possible for generating data for new registrations. Phosphor and
CRT manufacturers are also urged to re-measure data on old
registered phosphors and submit this new data to be published along
with the old data for comparison in future editions of this
publication.
