Gray scale display control device for field emission display

The utility model discloses a gray scale display control device for a field emission display, which is used for inputting externally inputted video signals to the field emission display to display, temporary storage for video gray scale data and conversion between frame video data and row video data are realized through a frame gray scale data storage control module and a row storage module, then a gray scale modulation module carries out data gray scale modulation on pixel points row by row according to row gray scale data, row-by-row display control for the field emission display is realized by being combined with a row scanning address generator, and finally video gray scale display of the field emission display is realized scene by scene. The gray scale display control device for the field emission display is simple in structure, easy to implement and good in applicability.
