Abstract
PURPOSE: To secure the highly effective application of the graphic memory by displaying the memory pattern of the graphic memory with the vertical and horizontal inversion at the actual displaying time.
CONSTITUTION: Refresh memory 10 memorizes the screen data to be displayed, and graphic memory 20 memorizes the graphic data to be displayed respectively. And the raster synchronous signal is delivered through timing circuit 40, and the pattern data corresponding to each screen data are delivered from pattern generating circuit 30. The memory pattern of memory 20 is displayed 6 with vertical and horizontal inversion at the actual displaying time. In such way, a highly effective application is ensured for memory 20.
