    Abstract: A spot detecting apparatus includes a photographing part and a spot detecting part. The photographing part photographs, in a first resolution, an image displayed on a display panel to output first resolution image data, and photograph, in a second resolution, the image displayed on the display panel to output second resolution image data, where the second resolution is higher than the first resolution, and the image displayed on the display panel includes a first spot greater than or equal to a reference size and a second spot less than the reference size. The spot detecting part receives the first resolution image data and the second resolution image data, and subtracts the first resolution image data from the second resolution image data to detect the second spot.

    Abstract: A display panel is divided into multiple areas respectively driven by multiple drivers, and the multiple areas are adjacent to each other along a first direction. An object moves along the first direction between a first frame and a second frame and is displayed on the display panel. The moving speed of the object is compared with a reference speed. A main compensation frame is added between the first frame and the second frame. A first high speed compensation frame is added between the first frame and the main compensation frame when the moving speed is higher than or equal to the reference speed. A first low speed compensation frame is added between the first frame and the main compensation frame when the moving speed is lower than the reference speed, and the first low speed compensation frame is different from the first high speed compensation frame.

    Abstract: A method of driving a display panel includes respectively outputting first to j-th, where j is a natural number, gate signals to first to j-th gate lines disposed on a first area of the display panel during a load period when an image is displayed on the display panel due to an output of a data signal to the display panel, adjusting a blank gate voltage during a blank period between load periods to generate an adjusted blank gate voltage, generating a blank gate signal based on the adjusted blank gate voltage, and outputting the blank gate signal. Thus, display quality of a display apparatus may be improved.
