1.前言在当前的信息社会中,LCD、VFD·EL,PDP等平板显示装置越加显得重要,其中LCD装置由于可实现大型彩色显示而发展的更快。做为背照明的热阴极管、冷阴极管及EL等,虽然也已达实用化,但仍存在亮度不高、发热及寿命不长等一系列问题。我们开发了高亮度的阴极射线发光背照光(back light)装置。在高速电子激发下的阴极射线发光情况下可使用效率高、色纯度好的RGB三基色荧光粉,这与VFD低速
1. Introduction In the current information society, flat panel display devices such as LCDs, VFDs, ELs, and PDPs have become more and more important, and LCD devices have been developed faster because of the large color display available. Although the hot-cathode tubes, the cold-cathode tubes, the EL and the like, which are backlights, have also been put into practical use, there are still a series of problems such as low brightness, heat generation and short service life. We have developed a high brightness cathode ray luminescence back light device. High-speed electron excitation under the conditions of the cathode ray can be used with high efficiency, good color purity RGB trichromatic phosphors, VFD low speed
