The present invention is characterized in that it is provided with a control circuit that generates a timing for transferring the image data multiple times during a period when M is positive or negative, and a gradation conversion ROM that divides the image data into a plurality of pieces and transfers them to a liquid crystal driving device for 16 gradations. LCD drive device.

Claims

[Scope of utility model registration request]

The image data stored in the memory is converted into a polarity signal CO.
A control circuit that generates a timing for transferring multiple times during a period when M is positive or negative, and a gradation conversion ROM that divides the image data into the plurality of parts and transfers them to the 16-gradation liquid crystal driving device are provided. Characteristic LCD drive device.
