Larger Screen FED Video Display System

The principle of field emission display integrated system was presented,which includes the transform and processing of digital video image and the transmission of video data,the interface circuit(about) HV632PG,the gray-shade column driving IC,and STV7697,the raw driving IC,as well as,FPGA control technology.Using this system,colour FED model was fabricated and used in the large screen low work function printing FED that could display color images for the first time.The integration of the system strongly reduced the complexity of the circuit,improved the stability of the system,made it thinner and lighter.The sample obtained its screen brightness about 200 cd/m~2,contrast ratio 600∶1,resolution 480×240,256 circuit gray scales and 63.5cm(25 in) display size.
