| Number | Title | Issue Date |
| 7034817 | Method and device of alignment of a video image with an edge of a display screen The aligning a video image with an edge of a display screen, the video image being displayed by a scanning of lines of the display screen by at least one electron beam modulated by a modulation signal, including, for each scanned line of the screen, storing successi... | 04/25/2006 |
| 6847176 | Apparatus and method for removing horizontal moire in cathode-ray tube monitors An apparatus and method for removing horizontal moire of a cathode-ray tube (CRT) monitor system, wherein horizontal moire can be completely removed even when the moire that occurs in an upper portion of the monitor is different from the moire that occurs in a lower... | 01/25/2005 |
| 6847337 | Driving apparatus and driving method for an electron source and driving method for an image-forming apparatus With the present invention, there is provided a driving method that favorably drives an electron source, which is driven in a passive matrix manner, without being affected by a disturbance. There is also provided an image-forming apparatus that uses this electron so... | 01/25/2005 |
| 6313878 | Method and structure for providing an automatic hardware-implemented screen-saver function to a display product A hardware-implemented screen-saver prevents burn-in of an image displayed on a screen of a display product by automatically reducing the video gain, and therefore the contrast, of the image when the portion of the image within a two-dimensional detection... | 11/06/2001 |
| 6225762 | Method and apparatus for providing moire effect correction on a multi-scan display monitor A moire adjustment circuit receives a horizontal synchronization signal having a horizontal scanning frequency and a moire adjustment signal substantially proportional to a horizontal spatial offset of alternate display lines on the display to correct the... | 05/01/2001 |
| 6023133 | Parabolic signal generator A parabolic signal generator (100) for use in a cathode ray tube (CRT) display circuit, comprising: programmable delay means (110) for receiving a CRT horizontal flyback signal and for producing a trigger signal which is delayed relative to the horizontal... | 02/08/2000 |
