Publication number: 20240144860Abstract: A display device includes: a memory; a pixel unit including first pixels disposed with a first density in a first area and second pixels disposed with a second density smaller than the first density in a second area in contact with the first area; and a degradation compensator which updates degradation information stored in the memory, based on input grayscales for the first and second pixels, and changes the input grayscales to output grayscales, based on the degradation information. The degradation compensator stores the degradation information in the memory in a unit of block for the pixel unit. The memory stores only first degradation information for each of first blocks including only the first pixels, stores only second degradation information for each of second blocks including only the second pixels, and stores the first and second degradation information for each of third blocks including both the first and second pixels.Type: ApplicationFiled: September 5, 2023Publication date: May 2, 2024Inventors: Seok Ha HONG, Hyung Jin KIM, Kyung Su LEE

Patent number: 7117413Abstract: A wrapped core linking module for accessing system on chip test includes a link control register that stores link control configuration between cores in a scan path of a system on chip according to control signals applied from an outside boundary. A link control register controller controls a shift and update link configuration by activating the link control register. A switch switches the scan path between wrapped cores based on the link control configuration of the link control register. An output logic connects the link control register to a test data out (TDO) of the chip in case of testing on chip or cores of system on chip.Type: GrantFiled: October 31, 2002Date of Patent: October 3, 2006Assignee: Korea Electronics Technology InstituteInventors: Chang Won Park, Sung Ju Park, Hyung Su Lee, Jae Hoon Song
