Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

[ EN ]

WHAT IS CLAIMED IS:

1. A method of increasing the horizontal resolution display of a video signal having a first frequency between two adjacent pixels in a horizontal row and a second frequency between the start of two adjacent horizontal rows of display, on a non-CRT display, said method comprising the steps of:
decreasing said second frequency to a third frequency thereby increasing the time between the start of said adjacent horizontal rows; and
increasing the number of pixels in each of said horizontal rows of display.

2. The method of claim 1 wherein said first frequency remains substantially the same.

3. The method of claim 1 wherein said non-CRT display is a display selected from TFT/LCD display, plasma display, FED display, OLED display, and LCD on silicon display.

4. A method of increasing the horizontal resolution display of a video signal having a first frequency between two adjacent pixels in a horizontal row and a second frequency between the start of two consecutive video frames, on a non-CRT display, said method comprising the steps of:
decreasing said second frequency to a third frequency thereby increasing the ■ time between the start of said consecutive video frames; and
increasing the number of pixels in each of said horizontal rows of display.

5. The method of claim 4 wherein said first frequency remains substantially the same.

6. The method of claim 4 wherein said third frequency is less than 60 Hz. and greater than 0 Hz.

7. The method of claim 6 wherein said third frequency is less than 50 Hz, and greater than 10 Hz.

8. The method of claim 7 wherein said third frequency is less than 30 Hz. and greater than 20Hz.

9. The method of claim 8 wherein said third frequency is substantially 24 Hz.

10. The method of claim 4 wherein said non-CRT display is a display selected from TFT/LCD display, plasma display, FED display, OLED display, and LCD on silicon display.

11. A method of displaying a video signal having a plurality of synchronization signals having a first frequency, with a plurality of pixel signals therebetween, with each synchronization signal representing the start of a video frame, said method comprising:
generating said video signal with said first frequency being less than 60 Hz. and greater than 0. Hz.; and
displaying said video signal on a non-CRT display.

12. The method of claim 11 wherein said first frequency is less than 50 Hz, and greater than 10 Hz.

13. The method of claim 12 wherein said first frequency is less than 30 Hz. and greater than 20Hz.

14. The method of claim 13 wherein said first frequency is substantially 24 Hz,

15. The method of claim 11 wherein said non-CRT display is a display selected from TFT/LCD display, plasma display, FED display, OLED display, and LCD on silicon display.

16. A video display for displaying a video signal having a plurality of
synchronization signals having a first frequency, with a plurality of pixel signals therebetween with each synchronization signal representing the start of a video frame, said display comprising:
means for generating said video signal with said first frequency being less than 60 Hz., and greater than 0 Hz.; and
a non-CRT display for receiving said video signal and for displaying said pixel signals.

17. The video display of claim 16 wherein said first frequency is less than 50 Hz, and greater than 10 Hz.

18. The video display of claim 17 wherein said first frequency is less than 30 Hz. and greater than 20Hz.

19. The video display of claim 18 wherein said first frequency is substantially 24 Hz.

20. The video display or claim 16 wherein said non-CRT display is a display selected from TFT/LCD display, plasma display, FED display, OLED display, and LCD on silicon display.

21. A method of improving the performance of a computer in generating a second video signal having increased- resolution for display compared to a first video signal, said first video signal having a plurality of pixel signals operating at a first clock rate with said first video signal having a first frame rate, said method comprising:
generating said second video signal having a second frame rate less than said first frame rate; and
displaying said second video signal on a non-CRT display.

22. The method or claim 21 wherein said second video signal comprises an increased number of pixel signals compared to said first video signal, with said pixel signals of said second video signal operating at substantially said first clock rate.

23. A method of increasing the distance of a cable connecting between a computer and a display device, with said computer generating a first video signal having a plurality of pixel signals operating at a first clock rate with said first video signal having a first frame rate, said method comprising:
generating a second video signal having a second frame rate less than said first frame rate by said computer;
supplying said second video signal over a cable; and
displaying said second video signal on a non-CRT display.

24. The method of claim 23 wherein said second video signal comprises an increased number of pixel signals compared to said first video signal, with said pixel signals of said second video signal operating at substantially said first clock rate.

25. A method of reducing radio frequency emission by a computer in generating a second video signal having increased resolution for display, compared to a first video signal, said first video signal having a first plurality of pixel signals operating at a first clock rate with said first video signal having a first frame rate, said method comprising:
generating said second video signal by said computer, said second video having a second frame rate less than said first frame rate, a second plurality of pixel signals greater than said first plurality and operating at said first clock rate;
supplying said second video signal over a cable; and
displaying said second video signal on a non-CRT display.
