Display apparatus
View Patent ↗A display apparatus includes a display panel including address electrodes and sustain electrodes crossing the address electrodes, with pixels being sandwiched between the address electrodes and the sustain electrodes. A sustain-electrode drive circuit selectively generates both sustain pulses and scan pulses and supplies them to the sustain electrodes. An address-electrode drive circuit generates address pulses based on a video signal and supplies the address pulses to the address electrodes. A control-signal generation circuit generates a control signal for controlling the sustain-electrode drive circuit to generate a selected one of the sustain pulses and the scan pulses and supplies the control signal to the sustain-electrode drive circuit. In order to display an image on the display panel, the sustain-electrode drive circuit both specifies addresses of pixels to be turned on and turns on the pixels at the specified addresses.
1. A display apparatus for displaying an image on a display panel, said display apparatus comprising:
a display panel provided with a plurality of first electrodes, a plurality of second electrodes arranged parallel to said first electrodes and a plurality of address electrodes arranged so as to cross to said first and second electrodes;
a first electrode drive circuit supplying first electrode sustain pulses to said plurality of first electrodes;
a second electrode drive circuit supplying scan pulses and second electrode sustain pulses to said plurality of second electrodes;
an address drive circuit supplying address pulses based on the image to said plurality of address electrodes; and
wherein said second electrode drive circuit includes a plurality of line drive circuits connected to said plurality of second electrodes respectively, and each of the line drive circuits has a driving switch for supplying said second electrode sustain pulses to the corresponding second electrode selectively, wherein said driving switch also supplies said scan pulses to said corresponding second electrode selectively, and wherein said driving switch includes:
a first switch element which supplies high level voltage of said second electrode sustain pulses and high level voltage of said scan pulses to said corresponding second electrodes, and
a second switch element which supplies low level voltage of said second electrode sustain pulses and low level voltage of said scan pulses to said corresponding second electrodes.
2. The display apparatus according to claim 1 , wherein a power collection circuit is provided for said plurality of line drive circuits in common, and said power collection circuit includes a capacitor and a coil connected between said plurality of line drive circuits and said capacitor.
