Publication number: 20100149435Abstract: A display device uses a field sequential color scheme. Assume that a panel video writing period defines a period from the start of writing image data into a display panel to the completion of displaying the image on the basis of the image data in a sub-frame. A light source driving circuit generates a driving signal for gradually increasing the luminance of a light source of a color corresponding to a displayed image in the present sub-frame from zero to a predetermined value within the panel video writing period of the present sub-frame and for gradually decreasing the luminance of the light source from the predetermined value to zero within the panel video writing period of the next sub-frame. A light source driver drives the light source to emit light in accordance with the driving signal.Type: ApplicationFiled: October 6, 2008Publication date: June 17, 2010Applicant: NEC DISPLAY SOLUTIONS, LTDInventor: Tooru Kataoka

Publication number: 20100134404Abstract: According to one embodiment, a video display apparatus includes a display module, a light source device, a video signal input module, a virtual illumination value calculator, a light source illumination value calculator, and a light source controller. The light source device is divided into light source areas in a honeycomb shape and provided with light sources to light up the light source areas. The virtual illumination value calculator calculates an area illumination value indicating the brightness of light source areas to light up based on a video signal received by the video signal input module. The light source illumination value calculator calculates a light source illumination value to light up the light sources based on the area illumination value. The light source controller lights up the light sources synchronously with the video signal being displayed on the display module based on the light source illumination value.Type: ApplicationFiled: June 16, 2009Publication date: June 3, 2010Applicant: Kabushiki Kaisha ToshibaInventors: Masaki Tsuchida, Ken Ito

Publication number: 20100118061Abstract: In a case where each of pixels of a liquid-crystal display panel is divided into two subpixels, the drive levels of the subpixels with respect to the gradation of an input video signal can be selected from among a plurality of drive levels while an increase in the circuit scale is suppressed. Thus, in the present invention, a first subpixel driving level converter for, on the basis of the gradation value of each pixel of the input video signal, obtaining a first gradation value for driving a first subpixel is provided, and the first subpixel is driven and controlled on the basis of the first gradation value. Then, the first gradation value obtained by the first subpixel driving level converter is converted into a luminance value, and a difference with the luminance value such that the gradation values of the whole pixels are converted is obtained. The obtained difference is converted into a gradation value, and a second gradation value for driving a second subpixel is obtained.Type: ApplicationFiled: March 28, 2008Publication date: May 13, 2010Applicant: SONY CORPORATIONInventors: Toshiaki Suzuki, Kazuhiro Nukiyama, Tsuyoshi Kamada

Publication number: 20100107207Abstract: The invention relates to a device for delivering audio and video data. In such a device, the audio/video data travel together and are compressed along with the signaling data for the delivery of these audio/video data. Under current compression standards, these data are being increasingly compressed. This maximum compression proportionally complexifies the encoding and decoding of audio/video data. The appearance of network cables comprising six twisted pairs of wires makes it possible to produce networks having higher speed capacities. The object of the invention is not to increase speeds by using additional twisted pairs but to simplify the data traveling through the network.Type: ApplicationFiled: March 11, 2008Publication date: April 29, 2010Inventor: Jean-Marc NOGIER

Publication number: 20100085492Abstract: The present invention relates to a hold type display device. One frame period that is a period when an image of one screen is displayed is divided into a dark display period when a relatively dark image is displayed and a bright display period when a relatively bright image is displayed. In the dark display period, each of scanning signal lines (GL1, GL2, GL3, etc.) is driven consecutively two times each during a period corresponding to one third of a conventional one horizontal scanning period. Also, in the dark display period, each two lines of the scanning signal lines (GL1, GL2, GL3, etc.) is driven at the same time. A gradation is calculated for generating a video signal such that, at two pixel formation portions arranged at intersections of these two scanning signal lines driven at the same time and a video signal line, a luminance averaged from luminances originally to be appeared at the two pixel formation portions appears.Type: ApplicationFiled: February 21, 2006Publication date: April 8, 2010Inventor: Makoto Shiomi
