Patent number: 10032405Abstract: An organic light-emitting display device and a method for driving the same are provided. The organic light-emitting display device analyzes input image data in unit of a window mask to detect a halftone data block, adjusts a voltage corresponding to grayscale 0 of center data disposed at the center of the halftone data block to a voltage higher than 0V, and adjusts the voltage corresponding to grayscale 0 in a data block other than the halftone data block to 0V, such that a data voltage swing width at low grayscales can be reduced so as to prevent voltage drop in pixels, thereby improving picture quality.Type: GrantFiled: December 29, 2015Date of Patent: July 24, 2018Assignee: LG DISPLAY CO., LTD.Inventors: Jaehyeong Jeong, Seonggyun Kim

Patent number: 8335214Abstract: Provided are an interface system and a method of controlling the interface system. The interface system may include a memory, a first processor, a second processor, and an interface unit. The memory may be configured to store received data in packets. The first processor may be configured to analyze a header of each of the packets to obtain analysis information. The second processor may be configured to receive and process a payload of the packet that includes the analyzed header and the payload. The interface unit may be configured to transmit only the payload to the second processor based on the analysis information. Since the interface system and the method may directly transmit only the payload of the packet to the processor without copying the payload to a separate memory, memory usage efficiency and system performance may be improved and power consumption may be reduced.Type: GrantFiled: March 10, 2009Date of Patent: December 18, 2012Assignee: Samsung Electronics Co., Ltd.Inventors: Jae-bok Lee, Ki-cheol Lee, Yong Ho Song, Jaehyeong Jeong
