Patent number: 10002568Abstract: A display unit of the disclosure includes a pixel array section and a drive section. In the pixel array section, unit pixels each including a light-emitting section are disposed. The drive section causes, during a non-display period other than a display period, a transistor to be corrected to be in an electrically conductive state, and performs, during the non-display period, light emission driving of the light-emitting section on a basis of a predetermined voltage. The transistor is provided in each of the unit pixels. The display period is a period during which display driving is performed on a basis of a display signal.Type: GrantFiled: February 13, 2015Date of Patent: June 19, 2018Assignee: JOLED Inc.Inventors: Gaku Izumi, Mikihiro Yokozeki

Patent number: 9224334Abstract: A display device includes pixels, each including a set of sub-pixels. A first subset of the pixels may each include white, green, and blue sub-pixels, but not a red sub-pixel. A second subset of the pixels may each include white, green, and red sub-pixels, but not a blue sub-pixel. The pixels may alternate between the first subset and the second subset in at least one direction. First luminance data may be extracted from an input image signal based on a map that specifies locations of pixels of the first subset, and second luminance data may be extracted from the input image signal based on a map that specifies locations of pixels of the second subset. The display device may drive the blue sub-pixels based on the first luminance data and drive the red sub-pixels based on the second luminance data.Type: GrantFiled: February 28, 2014Date of Patent: December 29, 2015Assignee: Sony CorporationInventors: Gaku Izumi, Seiichiro Jinta

Publication number: 20140035962Abstract: A signal processing circuit performs a correction on a first image signal to generate a noise-like pattern with regularity in an image, and thereby to generate a second image signal. Therefore, even if stripes or luminance unevenness is caused in a display image in the case where the first image signal is input into a display panel, a pattern making the stripes and the luminance unevenness less visible is allowed to be superimposed on the display image. Moreover, a pattern superimposed on the display image is the noise-like pattern with regularity which is obtainable without measuring light emission characteristics of the display panel. Therefore, it is not necessary to measure the light emission characteristics of the display panel to superimpose the above-described pattern on the display image.Type: ApplicationFiled: July 10, 2013Publication date: February 6, 2014Inventors: Gaku Izumi, Seiichiro Jinta
