Patent number: 11804195Abstract: The disclosure provides a display equipment, a brightness compensation device, and a brightness compensation method. The brightness compensation device includes a variable refresh rate (VRR) detection circuit and a control circuit. The VRR detection circuit and the control circuit receive a video stream from a video source device, and the video stream includes a VRR video frame. The VRR detection circuit detects a blanking period of the VRR video frame and generates a detection result. The control circuit outputs the frame data of the VRR video frame to the display device during the valid data period of the VRR video frame. The control circuit repeatedly outputs the frame data of the VRR video frame to the display device during the blanking period of the VRR video frame according to the detection result until the blanking period ends.Type: GrantFiled: April 27, 2021Date of Patent: October 31, 2023Assignee: Novatek Microelectronics Corp.Inventors: Po-Hsiang Huang, Chia-Hsing Hou, Yu-Lin Cheng, Chung-Wen Wu
