Our daily activity is supported with information stored in tiny tips in computers that are invisible by the naked eyes. The stored information of PC and TV broadcasting images displays on lighted phosphor screens. Comfortable images on the phosphor screens for the naked eyes should be equivalent with the daytime scenery under slightly overcastting sky {10 25 visible photons (m2, s) -1} that the eyes have adjusted for 5 million years. We have developed the CRTs that display the required images on the phosphor screen as the consequence of the statistical study on the sizes of the phosphor particles. Phosphor screens in CRT are constructed with the polycrystalline phosphor particles in the size at around 5 x 10-6 m. The phosphor powder in 1 gram contains 3 x 1020 particles that should distribute with a log-normal distribution. Then, we have significantly increased the luminance to 100 ft-L (equivalent to 330 lumens m-2) from 7 ft-L by the change in the operation conditions of the phosphor particles after the measurements of the VD and CD curves of CL. The sharp and stable images on the lighted phosphor screen in CRTs are only obtained with the phosphor particles that have the clean surface chemically and physically.
