Abstract: A display apparatus includes a light guide member disposed below a display member. A light source configured to generate light is disposed adjacent to the light guide member. The light guide member includes a plurality of diffraction on the light guide member. The diffraction patterns are spaced apart from each other in the first direction. The plurality of diffraction patterns diffract incident light, which is incident at an incident angle, to change the incident light to diffraction light having a diffraction angle. The incident angle is defined as an angle between the incident light and a normal line that is perpendicular to a top surface or a bottom surface of the light guide member. The diffraction angle, which is defined as an angle between the diffraction light and the normal line, has a magnitude less than that of the incident angle.

Abstract: 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.
