Patent number: 11996048Abstract: A display device includes a display panel including pixels coupled to a first scan line and a data line, a power supply to supply voltages, a scan driver to provide a first scan signal to the first scan line a plurality of times for a first frame period (FFP), a data driver to supply a data signal to the data line, and a timing controller to control driving of components. The FFP includes: a first active period (FAP), in which the data signal is supplied; and a first blank period (FBP), in which the data signal is not supplied. The power supply provides on-bias power having a first voltage level (FVL) in the FAP, and provides on-bias power having a second voltage level (SVL) in the FBP. The FBP following the FAP includes a first dimming period in which the on-bias power gradually changes from the FVL to the SVL.Type: GrantFiled: May 4, 2023Date of Patent: May 28, 2024Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Se Byung Chae, Seung Kyu Lee
