FED新型灰度调制系统的研制

The Design of Sub-Row Gray-Scale Modulating System of FED

描述了FED新型灰度调制系统的构成,采用PDP驱动芯片uPD16347,利用其优越的高压驱动特性,通过FPGA模拟PWM进行控制,实现FED屏的驱动,本文还引入了误差扩散法,阐述了其在FED新型灰度调制系统中的作用,对现阶段的FED驱动电路的设计具有重要的意义。

The new method of gray-scale modulating system of FED is described, We adopt PDP chip-uPD16347,because of its ascendant capacity in high voltage drive. Realization the driving circuit of FED by using FPGA for controlling, Introduce method of error diffusion, expound it＇s function which improved gray scale in the system, It played an important role in FED driving circuit on the present stage.
