Abstract
Abstract A plasma display includes a mode discrimination/clock generator (15). A CRT display controller (1) generates vertical and horizontal sync signals having polarities. The mode discrimination/clock generator (15) discriminates the polarities of the vertical and horizontal sync signals to determine a display resolution. Anode and cathode timing generators (12, 16) generate display timing signals in accordance with the display resolution.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
136 words
A plasma display control system having a CRT display controller (1), which comprises a plasma display and allows a CRT display to be connected thereto as an option, for outputting vertical and horizontal sync signals having polarities to said CRT display and said plasma display, characterized in that there are provided: display resolution discriminating means (15) for discriminating the polarities of the vertical and horizontal sync signals output from said CRT controller, and determining selectable display resolution in accordance with the combination of polarities of the signals; display timing generating means (12, 16) for generating a display timing signal in accordance with the selectable display resolution determined by said display resolution discriminating means; and drive means (17, 18) for driving said plasma display responsive to the display timing signal generated by said display timing generating means.
Claim 2
Dependent Claim
136 words
A plasma display control system having a CRT display controller (1), which comprises a plasma display and allows a CRT display to be connected thereto as an option, for outputting vertical and horizontal sync signals having polarities to said CRT display and said plasma display, characterized in that there are provided: display resolution discriminating means (15) for discriminating the polarities of the vertical and horizontal sync signals output from said CRT controller, and determining selectable display resolution in accordance with the combination of polarities of the signals; display timing generating means (12, 16) for generating a display timing signal in accordance with the selectable display resolution determined by said display resolution discriminating means; and drive means (17, 18) for driving said plasma display responsive to the display timing signal generated by said display timing generating means.
Claim 3
Dependent Claim
30 words
A system according to claim 1, characterized in that said display resolution discriminating means, said display timing signal generating means, and said drive means are incorporated in said plasma display.
Claim 4
Dependent Claim
26 words
A system according to claim 1, characterized in that selectable display resolutions include 640 × 350 dots, 640 × 400 dots, and 640 × 480 dots.
Claim 5
Dependent Claim
49 words
A system according to claim 1, characterized in that said display timing signal generating means generates the display timing signal so that a display area is set at a central position of said plasma display when the display resolution is below a maximum display resolution of said plasma display.
Claim 6
Independent Claim
112 words
A method of controlling a plasma display having a plurality of display resolutions and included in a CRT display controller which allows a CRT display to be connected thereto as an option, and outputs vertical and horizontal sync signals and data signals of data to be displayed on said CRT display and said plasma display, comprising: discriminating the polarities of the vertical and horizontal sync signals output from said CRT controller, and determining a display resolution in accordance with the combination of the polarities of the signals; generating a display timing signal in accordance with the determined display resolution; and driving said plasma display in response to the generated display timing signal.
Claim 7
Independent Claim
112 words
A method of controlling a plasma display having a plurality of display resolutions and included in a CRT display controller which allows a CRT display to be connected thereto as an option, and outputs vertical and horizontal sync signals and data signals of data to be displayed on said CRT display and said plasma display, comprising: discriminating the polarities of the vertical and horizontal sync signals output from said CRT controller, and determining a display resolution in accordance with the combination of the polarities of the signals; generating a display timing signal in accordance with the determined display resolution; and driving said plasma display in response to the generated display timing signal.
