Input integrated flat panel display system

An input integrated flat panel display system comprising:

• an input integrated flat panel display having an integrated structure, including input means for inputting handwritten data in the form of characters, graphics, and points, and a flat display panel laid upon said input means for displaying information corresponding to input point data input through said input means;
• processing means for distinguishing whether said input point data relates to characters or graphics and for providing display point data to the flat display panel;
• large screen frame memory means coupled between said flat panel display and said processing means for storing display point data for a large screen having a larger display area than that of said flat display panel;
• flat panel display frame memory means for storing display point data for display on said flat panel display;
• register means responsive to said input means for storing a start address indicative of a portion of said display point data for the large screen which is to be displayed on said flat display panel;
• transformation control means for transforming said input handwritten data into display point data for said large screen and for transferring said display point data to said processing device based upon the start address stored in said register means;
• and
• display control means responsive to the start address from said register means, for extracting a portion of said display point data for said large screen from said large screen frame memory means and for transforming said extracted portion into display point data for display on said flat display panel.

An input integrated flat panel display system comprising:

• (a) an input integrated flat panel display structure including input means for inputting handwritten data in the form of characters, figures and points and a flat panel display integrated with said input means for displaying an image corresponding to said input handwritten data from said input means;
• (b) processor means coupled to said input means for discriminating whether said input handwritten data is a character or a figure and for providing display point data for display by said flat panel display;
• (c) control means coupled between said input means and said processor means for transforming input data from said input means into display point data for a large display screen, based on the start address held in said start address providing means, and for transferring said transformed display point data to said processor means;
• (d) frame memory means coupled to said processor means for storing display point data received from said processor means, said frame memory means having a capacity for storing display point data for a large display screen having a larger display area than that of the flat panel display;
• (e) start address providing means responsive to said input means for holding a start address designating which portion of said display point data stored in said frame memory means is to be displayed on said flat panel display;
• and
• (f) display control means, connected between said frame memory means and said flat panel display and responsive to the start address from said start address providing means, for extracting from said frame memory means a portion of said display point data for said large screen and for transforming the extracted portion into display point data for said flat panel display screen to display the transformed data thereon.

For use in a display system having a processor providing display point data, a frame memory for storing display point data, and a display device having a large image screen for displaying display point data, a display data processing system comprising:

• (a) an input integrated flat panel display structure including input means for inputting handwritten data in the form of characters, figures and points, and flat panel display which is smaller than said large image screen and is integrated with said input means for displaying an image corresponding to said handwritten input data as a partial image of an image displayed on the large image screen;
• (b) register means responsive to a position designation signal from said input means for holding a start address designating which portion of display point data for the large image screen is to be displayed on said flat panel display;
• (c) first display point data transformation means responsive to said input means for transforming handwritten input data into display point data for the large image screen, based on the start address held in said register means;
• and
• (d) second display point data transformation means responsive to the start address held in said register means for extracting a portion of said display point data for the large image screen and for transforming the extracted portion into display point data for the flat panel display, to thereby provide data for display of a partial image formed by the transformed data on the flat panel display, simultaneously with display of an entire image formed by the display point data from said first display point data transformation means on the display device having the large screen.
