Patent number: 9424805Abstract: A display drive integrated circuit includes a frame buffer, an output selector and a timing controller. The output selector selectively outputs one of image data read from the frame buffer and image data transmitted from a source external to the display drive integrated circuit. The timing controller controls output of the image data read from the frame buffer to the display panel in a self-refresh mode, and controls internal display timing to track external display timing when the display drive integrated circuit exits from the self-refresh mode to control the output selector to output the image data transmitted from the source to the display panel when the internal display timing is synchronized to the external display timing.Type: GrantFiled: March 5, 2014Date of Patent: August 23, 2016Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Jong-Sung Lee, Se-Moon Oh, Byung-Koan Kim, Dustin Yuk Lun Wai, Hye-Jin Jung

Patent number: 8139014Abstract: Provided are a skew adjustment circuit and a method thereof. The skew adjustment circuit inputs an input clock signal and an input start pulse signal to output an output clock signal and an output start pulse signal which are delayed according to a skew value of a skew control signal. The skew adjustment circuit includes a delay circuit, a selection circuit, and an output circuit. The delay circuit delays an input clock signal by a skew value in response to a skew control signal to generate an output clock signal. The selection circuit compares the skew control signal and an offset control signal to select one of the input start pulse signal and a delayed start pulse signal to output the selected signal as a start pulse signal. The output circuit responds to the output clock signal to output the start pulse signal as an output start pulse signal.Type: GrantFiled: October 8, 2008Date of Patent: March 20, 2012Assignee: Samsung Electronics Co., Ltd.Inventors: Byung-koan Kim, Ock-chul Shin, Young-chul Rhee

Patent number: 7852121Abstract: A domino logic circuit includes an input circuit and an output circuit. The input circuit precharges a dynamic node at a first phase of a clock signal. The input circuit determines a logic level of the dynamic node by performing a logic evaluation of input data at a second phase of the clock signal. The output circuit is coupled between an output node and the dynamic node. The output circuit determines a logic level of the output node in response to the clock signal and the logic level of the dynamic node. The output circuit maintains the logic level of the output node while the logic evaluation is performed.Type: GrantFiled: March 11, 2009Date of Patent: December 14, 2010Assignee: Samsung Electronics Co., Ltd.Inventors: Young-Chul Rhee, Byung-Koan Kim, Ock-Chul Shin
