Abstract

A system using an input integrated flat panel display of an integrated structure, having an input device for inputting through handwriting characters, graphics, or points and a flat panel display laid upon the input device for displaying in accordance with an input point data input through handwriting. The frame memory of a large screen having a display screen larger than that of the flat panel display is arranged to be read out through the input device of the input integrated flat panel display. In addition, the readout contents of the large screen frame memory is arranged to be copied onto the flat display of the input integrated flat panel display. The input integrated flat panel display system can improve the man-machine performance while the amateur end user performs document processings, graphic processings and the like.

4. An input integrated flat panel display system according to claim 3, wherein the start address for the point data for said large screen is changed by said changing means in accordance with the direction, distance, and speed of a stroke by said coordinate input pen for changing the start address on said scroll appointment section.

5. An input integrated flat panel display system according to claim 1, wherein said input means includes a zooming display section including means for appointing a zooming display, said zooming display section being integrated with said flat display panel, said transformation control means including means responsive to said zooming display section for changing the magnification of transformation of said input handwritten data into said display point data for said large screen, and said display control means includes means for extracting a portion of said display point data for said large screen, said extracted portion being proportional to a reciprocal of said magnification of transformation, and for displaying said extracted portion on said flat display panel.

6. 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.

7. An input integrated flat panel display system according to claim 6, wherein scroll appointment means for changing said start address is integrated with said flat display panel, and includes means for changing the transfer of said input handwritten data to said control means and the extracting of the display point data for said large screen at said display control means by changing the start address for the point data for said large screen.

8. An input integrated flat panel display system according to claim 6, further comprising color appointment means integrated with said flat panel display for appointing color information, said transformation control means and said display control means being controlled by said color information so that the appointed color is displayed on said flat display panel.

9. 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.
