Abstract

A display device for use as a computer monitor, the display device comprising: a flat panel display for displaying images received from a computer; and a printer, the printer including a pagewidth printhead for printing onto print media, the printhead being disposed adjacent a lower portion of the display device.

Claims

1. A display device for use as a computer monitor, the display device comprising:

a flat panel display for displaying images received from a computer; and

a printer, the printer including a pagewidth printhead for printing onto print media, the printhead being disposed adjacent a lower portion of the display device.

2. A display device according to claim 1, further including a print media feed mechanism for feeding print media to the printhead for printing.

3. A display device according to claim 2, wherein the print media feed mechanism is configured to position the paper substantially parallel in at least one direction with respect to a plane defined by the flat panel display.

4. A display device according to claim 3, wherein the print media feed mechanism is configured to accept a single sheet of paper at a time for printing.

5. A display device according to claim 3, wherein the print media feed mechanism includes a paper separator for feeding a single sheet of paper to the printhead from a stack of sheets of paper.

6. A printing and display device according to claim 1, wherein the printing and display device includes a connection configured to allow releasable operative connection of the computer system to the printing and display device, for receiving the print data and the display data from the computer system.

7. A printing a display device according to claim 6, wherein the connection includes at least one socket for accepting at least one corresponding data cable.

8. A printing and display device according to claim 6, wherein the connection includes a wireless receiver for receiving the print data and/or the display data.

9. A printing and display device according to claim 6, wherein the connection is a Universal Synchronous Bus (USB) connection.

10. A printing and display device according to claim 1, wherein the printer is a process color printer.

11. A printing and display device according to claim 1, wherein the printer is an inkjet printer.

12. A printing and display device according to claim 11, wherein the printer has more than 5,000 inkjet nozzles.

13. A printing and display device according to claim 1, wherein the flat panel display measures at least 14 inches on the diagonal.

14. A printing and display device according to claim 1, including at least two of the printheads, the printheads being disposed on either side of a path through which the paper is fed for printing, thereby enabling substantially simultaneous printing of both sides of a sheet of paper.

15. A printing and display device according to claim 1, configured to enable printing of standard A4 or Letter sized sheets of paper.

16. A printing and display device according to claim 1, configured such that paper to be printed is fed manually into a paper path that directs the paper from a region adjacent the upper edge of the flat panel display, past the printhead for printing, then out of the device adjacent a lower edge of the flat panel display.

17. A printing and display device according to claim 1, further including a curved paper guide disposed, when the device is in use, beneath the flat panel display, such that the paper that has been printed is urged horizontally as it exits the device.

18. A printing and display device according to claim 1, wherein the flat panel display is of one of the following types:

Liquid Crystal Display (LCD);

Organic Light Emitting Diode (OLED)

Field Emission Display (FED)

Plasma Display Panel (PDP)

19. A display device as claimed in claim 1, the display device comprising:

a flat panel display for displaying images from a computer;

a printhead for printing onto print media;

a sheet feeder for receiving at least one sheet of the print media and feeding the at least one sheet to the printhead for printing, wherein the sheet feeder is at least partially fed by gravity.

20. A display device as claimed in claim 1, the display device comprising:

a flat panel display for displaying images from a computer;

a stand for holding the flat panel display in at least one operative position; and

a printer, the printer including a printhead for printing onto paper;

wherein the stand is configured such that the at least one operative position includes one in which the flat panel display makes an angle of 0 to 45 degrees to the vertical.

21. A display device as claimed in claim 1, the display device comprising:

a flat panel display for displaying images from a computer;

a printer, the printer including;

(a) a printer controller configured to receive print data in a compressed form, decompress the print data, and output dot data based on the decompressed print data;

(b) a pagewidth printhead for receiving the dot data and printing onto print media.

22. A display device as claimed in claim 1, the display device comprising:

a flat panel display;

a printer, including a printhead for printing onto paper; and

a print media print path along which print media is supplied to the printer, wherein at least a majority of the print path is in a plane that is substantially parallel to a plane defined by the flat panel display.

23. A display device as claimed in claim 1, the display device comprising:

a flat panel display;

a printer, including a printhead for printing onto paper; and

a sheet feeder for feeding print media to the printhead, the device being configured such that standard print media to be printed is supported, immediately prior to commencement of printing, such that at least an edge of the print media is visible above an upper edge of a the flat panel display.

24. A display device as claimed in claim 1, the display device comprising:

a flat panel display for displaying images from a computer, the flat panel defining a plane;

a printer, including a pagewidth printhead for printing onto print media; and

a print media print path along which print media is supplied to the printer, wherein at least a majority of the print path is parallel to the plane in at least one direction.

25. A display device as claimed in claim 1, the display device comprising:

a flat panel display for displaying images received from a computer system; and

a printer, the printer including a pagewidth printhead for printing onto print media, the pagewidth printhead extending across a majority of the width of the device.
