General display driving device and method for display screen of DCS platform of nuclear power plant

The invention discloses a general display driving device and method for a display screen of a DCS platform of a nuclear power plant. The device comprises a state management module, a data processing module, an icon splicing module and a chip driving module; the data processing module converts display information required by each board card into ASCII code values of corresponding display characters; the icon splicing module calls character data of the corresponding display characters from a word stock according to a state output by the state management module and the ASCII code values output by the data processing module, performs data splicing, and then stores the character data with coordinates and an address in a built-in RAM block; any bit in the built-in RAM block can be freely controlled; the state management module performs display screen state management and transmits different data to the chip driving module according to different states; and the chip driving module transmits the data to a control chi
