标志性成果3： FED显示器与FED背光源

FED显示器研究进程 /FED Display and Related Prototypes

自1989年始，我们先后在福建省科技厅重点专项、 国家科技部863计划的长期支持下，采用新型微纳材料、 复合阴极组件、微纳阴栅器件结构、低逸出功阴极激活技术、子行驱动技术和真空封接技术，研制成功4英寸、 20英寸、25英寸、34英寸单色和彩色印刷FED显示器， 其中34英寸彩色FED显示器的阴极逸出功低于1 eV,分辨 率1024x3x720,最高亮度500 cd/m2,灰度等级256级，对比度4000:1。34英寸彩色印刷FED显示器是中国最好的FED显示器，也是国际上 第三大FED显示器，开辟了第三条大屏幕低成本FED显示器技术路线。相关技术已应用 于高性能LCD显示器和电视机产品开发中.

Since the beginning of 1989, under the long-term support of the key special project of Fujian Provincial Science and Technology Department and National Science and Technology 863 Program, we have applied the new micro-nano material, composite cathode assembly, micro-nano- gate device structure, low work function cathode activation technology, sub-line drive technology, and vacuum sealing technology, to successfully develop monochrome and color printing FED display monitors with the size of 4 inches, 20 inches, 25 inches and 34 inches. Among them, the 34- inch color FED display has a cathode work function below 1 eV, a resolution of 1024 x 3 x 720, a maximum brightness of 500 cd / m2, a grayscale level of 256, and a contrast ratio of 4000: 1. The 34-inch color printing FED display monitor is the best FED display monitor in China and it is also the world*s third-largest FED display monitor, which opens up the third large-screen and low-cost FED display technology line. The related technologies have been used in the development of high performance LCD displays and television products.

FED背光源的研究进程 /FED Backlight and Related Prototypes

与传统荧光灯背光源不同，FED背光源是一种轻薄高效、调节简易的背光源， 特别适用于制作局域动态调光调色显示器背光源和照明器具。自2004年开始，我们 先后在福建省科技厅和福建省发改委重点专项支持下，采用新型微纳材料、复合阴 极组件、低逸出功阴极激活技术、真空封接技术和宽域调光调色技术，研制成功 20英寸、25英寸、34英寸单色和白光印刷FED背光源，其中34英寸白光印刷FED背 光源的阴极逸出功1.1eV,最高亮度8000 cd/m2,调光调色范围100%. 34英寸白 光印刷FED背光源是中国最好的FED背光源，也是国际上第二大FED背光源，开辟 了第二条大屏幕低成本FED背光源的技术路线。相关技术已应用于高性能LCD背光模组产品开发中。

Unlike traditional fluorescent backlight, the FED backlight is a lightweight, highly efficient, and easy-to-adjust backlight that is particularly suitable for making the local dynamic dimming color display backlight and the lighting device. Since 2004, under the support of the key special project of Fujian Provincial Science and Technology Department and Fujian Provincial Development and Reform Commission, we have applied the new micro-nano material, composite cathode assembly, low work function cathode activation technology, vacuum sealing technology, and wide-area dimming technology to successfully develop monochrome and white printing FED backlights with the size of 20 inches, 25 inches and 34 inches. Among them, the 34-inch color FED backlight has a cathode work function of 1.1 eV9 a maximum brightness of 8000 cd / m2, and dimming color range 100%. The 34-inch white printing FED display monitor is the best FED backlight in China and it is also the world，s second-largest FED backlight, which open up the second large-screen and low-cost FED backlight technology line. The related technologies have been used in the development of high performance LCD backlight module products.
