Patent number: 10529272Abstract: A display apparatus includes a visual information inputting part, a mode determining part, a driver and a display panel. The visual information inputting part receives an eyesight of a user and a viewing distance of the user. The mode determining part determines a pixel perception distance based on the eyesight of the user and compares the viewing distance and the pixel perception distance to select one of a normal mode and a control mode. The driver maintains a vertical resolution of an input image and a frame frequency when the normal mode is selected, and outputs gate signals to gate lines during a same horizontal period to decrease the vertical resolution and inserts a compensation frame between adjacent frames to increase the frame frequency when the control mode is selected. The display panel displays an image based on the vertical resolution and the frame frequency set by the driver.Type: GrantFiled: May 2, 2018Date of Patent: January 7, 2020Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Kang-Min Kim, Mira Gwon, Nam Heon Kim, Hasook Kim, Junghwan Yi, Sunkyo Lim
