Abstract

The needs for large screen displays is increasing and with the introduction of higher quality picture, the demand will grow even more. Larger size picture tubes are becoming very common now in today's industry. But there are limitations in the direct view tube technology because of glass strength, weight, performance and cost. The CRT projection system was developed in order to achieve a much larger picture with easier technology and lower cost. At the early stage of CRT projection development, the obtained picture was only a very dim, vague and low contrast one. Intense investigations were done in this area and many improvements were accomplished. The improvements are not limited only to the tube, but also to the optical system (lens and screen) and its system design. As a result, we have achieved very bright picture having good contrast. Total performance of latest projectors is even better than direct view tube systems. In the coming era of HDTV, displays have to have much larger screen and higher resolution. We think the CRT projection system will play a big role in this field.
