Brightness improvement is a very important issue in color monitor tube (CMT), especially in multimedia display and low power issue. Multimedia applications require brightness at higher levels, and lower power tube is for energy saving. In this report, we will discuss the factors that affect brightness and its relative items-brightness uniformity and color purity of the CMT. There are many items which will improve the brightness, brightness uniformity and color purity. They include improving phosphors efficiency, changing the color points of phosphors, Cr-free photoresist, reducing the electron backscattering, increasing the uniformity of aluminum layer and matrix hole size, improving the landing and doming phenomena, a good screen outside coating and a good panel glass transmission, etc. We will discuss these items in this report.
