Publication number: 20030122737Abstract: 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.Type: ApplicationFiled: December 17, 2002Publication date: July 3, 2003Inventors: Makoto Onozawa, Yuji Sano, Michitaka Ohsawa, Takashi Sasaki, Noboru Akiyama, Fumitaka Asami, Kazuo Yoshiikawa, Hitoshi Hirakawa, Tomokatsu Kishi, Toyoshi Kawada

Publication number: 20020149577Abstract: An image display apparatus capable of adjusting a display picture by an input unit through a computer body is disclosed. When the user inputs a control instruction for adjusting the display picture of the display unit by the input unit connected to the computer body, a control signal addition circuit prepares a control signal Sc corresponding to the control instruction and adds the control signal to a video signal R, G or B or a synchronizing signal Hs or Vs produced by a display control circuit during a vertical retrace period. A control signal separation circuit separates the added control signal Sc from the video signal R, G or B or the synchronizing signal Hs or Vs produced by the control signal addition circuit.

Publication number: 20010033009Abstract: A low-cost display driver module that shortens the process for connecting an integrated circuit chip and a wiring pattern on a flexible wiring board and uses a metal chassis on a display panel as a radiator. In this display driver module, an integrated circuit chip with bump electrodes on it is joined with pressure applied by the use of an anisotropic conductive film, an anisotropic conductive paste, a non-conductive resin paste, or a non-conductive resin film and the back of the integrated circuit chip is adhered to a metal chassis on a display panel by the use of an integrated-circuit chip adhesive. As a result, the metal chassis can be used as a radiator for the integrated circuit chip. Batch bonding will enable to shorten time for the connection process and to cut down the cost of installations. Furthermore, a radiator is unnecessary, resulting in a low-cost display driver module.Type: ApplicationFiled: April 6, 2001Publication date: October 25, 2001Inventors: Hirokazu Inoue, Toyoshi Kawada, Yuji Sano, Michitaka Ohsawa, Osamu Hirohashi
