Patent number: 10345971Abstract: According to one embodiment, a display device includes a display panel, switching elements, a power supply, a controller and a noise suppression circuit. The display panel displays an image. The switching elements supply a pixel signal to the display panel. The power supply supplies a power source voltage to the switching elements. The controller switches between a display period during which the display panel displays an image and a non-display period during which the display panel does not display an image. The noise suppression circuit preliminarily reduces a potential difference between the switching elements and the power supply when the controller switches between the display period and the non-display period.Type: GrantFiled: April 26, 2016Date of Patent: July 9, 2019Assignee: Japan Display Inc.Inventors: Takashi Yoshii, Jin Ota

Patent number: 10172268Abstract: A component mounting device includes a mounting head that is movable in a horizontal direction and mounts a held component on a substrate and a control portion that controls the operation of the mounting head. The control portion is configured to perform control of a speed of mounting, by the mounting head, of a component to be located closely adjacent to another component and to be mounted on the substrate such that an interval to an adjacent component is equal to or less than a predetermined threshold, on the substrate. A speed of mounting of the component is less than a speed of mounting in a normal state in which the mounting head mounts a component, which is not the component to be located closely adjacent to another component, on the substrate.Type: GrantFiled: September 22, 2016Date of Patent: January 1, 2019Assignee: YAMAHA HATSUDOKI KABUSHIKI KAISHAInventors: Seiji Ohnishi, Koichi Izuhara, Hiroyuki Watanabe, Takashi Yoshii

Patent number: 8462266Abstract: An image processing device and method, and an image display device and method which realizes a high-definition displayed video by reducing motion blur caused by a holding-type display system and reducing motion blurs of the displayed video caused by the time integration effect of an image sensor while suppressing deterioration of an image. The image display device includes a motion vector detection section (101) which detects a motion vector in each predetermined region between the frames of an inputted image signal, and an edge emphasis part (2) which emphasizes the high-frequency component of the inputted image signal and an interpolated image signal generated by an FRC part (100) according to the motion amount of the inputted image signal detected by the motion vector detection section (101). This compensates the high-frequency component attenuated by the time integration effect of the image sensor to reduce the apparent motion blurs to improve the sharpness of the displayed image.Type: GrantFiled: April 18, 2008Date of Patent: June 11, 2013Assignee: Sharp Kabushiki KaishaInventors: Masafumi Ueno, Kenichiroh Yamamoto, Takashi Yoshii, Hiroyuki Furukawa, Yasuhiro Yoshida, Ikuko Tsubaki
