Patent number: 9035977Abstract: A display control drive device sequentially reads display data from a display memory in which the display data is stored, produces three primary color image signals that are applied to pixel locations in a dot-matrix color display device, and transmits the signals through a common external output terminal in a time-sharing manner. The display control drive device produces control signals applied to selection switching elements in the display device and that selectively apply an input image signal to any of three source lines. The display control drive device includes: a unit that determines one horizontal period based on a clock received from outside synchronously with display data; and a signal production circuit that produces and transmits the control signals, applied to the selection switching elements, so that the control signals will have a pulse duration equivalent to a time calculated by trisecting one horizontal period.Type: GrantFiled: December 9, 2013Date of Patent: May 19, 2015Assignee: Synaptics Display Devices KKInventors: Yasuhito Kurokawa, Kunihiko Tani

Patent number: 8941578Abstract: In conventional liquid crystal display controllers, the display is reduced in the stand-by state but the liquid crystal display duty is not changed, i.e., even the common electrodes of the rows that are not producing display are scanned, and the consumption of electric power is not decreased to a sufficient degree in the stand-by state. A liquid crystal display controller includes a drive duty selection register capable of being rewritten by a microprocessor, and a drive bias selection register. When the display is changed from the whole display on a liquid crystal display panel to a partial display on part of the rows only, the preset values of the drive duty selection register and of the drive bias selection register are changed, so that the display is selectively produced on a portion of the liquid crystal display panel at a low voltage with a low-duty drive.Type: GrantFiled: July 11, 2013Date of Patent: January 27, 2015Assignee: Renesas Electronics CorporationInventors: Yoshikazu Yokota, Kunihiko Tani, Gorou Sakamaki, Katsuhiko Yamamoto, Takashi Yoneoka, Kazuhisa Higuchi, Kimihiko Sugiyama

Patent number: 7834835Abstract: In a display control drive device that displays an image on a display device, a data transfer rate may vary depending on received image data because of a difference in an image size. Assuming that driving force with which a driver or an amplifier is driven is designed based on a maximum data transfer rate and the driver or amplifier is operated with the driving force, when the transfer rate is low, an unnecessary current is consumed. According to the present invention, a display control drive device sequentially reads display data from a display memory in which the display data is stored, produces three primary color image signals that are applied to pixel locations in a dot-matrix color display device, and transmits the signals through a common external output terminal in a time-sharing manner.Type: GrantFiled: April 10, 2007Date of Patent: November 16, 2010Assignee: Renesas Electronics CorporationInventors: Yasuhito Kurokawa, Kunihiko Tani
