Patent number: 10839755Abstract: A display device includes a display panel including gate lines, data lines, and pixels individually connected to a corresponding gate line and data line, a gate driver driving the gate lines, a data driver driving the data lines, and a driving controller. The driving controller receives, from an external source, first image signals and a variable frequency signal indicating an operation frequency (frame rate) for the display device. The driving controller converts the first image signals to second image signals by adding a compensation value corresponding to the operation frequency to the first image signals, and outputs the second image signals to the data driver. Embodiments may compensate for luminance reduction/variation and reduce image artifacts that otherwise occur due to variable frequency operation. An alternative embodiment dynamically controls an amount of light output from a backlight according to the variable frequency signal.Type: GrantFiled: August 30, 2018Date of Patent: November 17, 2020Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Tae-seok Ha, Kyung-hun Lee, Sucheol Kang, Jongwoon Kim, Kyu-jin Park, Sung-jae Park, Seung-woon Shin
