    Abstract: A display device includes a display panel including first to fourth panel pads and a connection board including first to fourth connection board pads coupled to the first to fourth pads, respectively. The first and second panel pads are electrically connected to each other, and the third and fourth panel pads are electrically connected to each other. The connection board includes a driving circuit which generates a first test result signal based on a first panel test signal transmitted to the first connection board pad and a first panel feedback signal received from the second connection board pad, generates a second test result signal based on a second panel test signal transmitted to the third connection board pad and a second panel feedback signal received from the fourth connection board pad, and sequentially outputs the first and second test result signals as a test result signal.

    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.
