Abstract: A display apparatus includes a display panel including display blocks, where each of the display blocks includes a plurality of pixels, a gate driver which outputs gate signals to the pixels, a data driver which receives image data and outputs data voltages corresponding to the image data to the pixels, and a timing controller which converts an image signal input thereto, outputs the converted image signal to the data driver as the image data, and controls a driving timing of the gate driver and the data driver. The timing controller controls output timings of at least data voltages output to pixels of a predetermined display block among the data voltages provided to the pixels of the display blocks, depending on a color pattern of the image signal corresponding to the pixels of the predetermined display block.

Abstract: A display device includes a display panel, a first circuit board, a control unit disposed on the first circuit board, a second circuit board, and a coupling film which electrically couples the control unit and the second circuit board to each other. The coupling film includes a first coupling part including a first region attached to the first circuit board, and a second region overlapping the display panel when viewed in a thickness direction of the display panel, a second coupling part including a third region attached to the second circuit board, and a fourth region overlapping the display panel when viewed in the thickness direction of the display panel, and a third coupling part coupled to each of the second region and the fourth region to electrically couple the first coupling part and the second coupling part to each other.
