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.

Display device coupled to circuit board with coupling film

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.

Display apparatus and method of driving the same

A power voltage generating circuit includes an input part, a clock determining part and a plurality of switches. The input part receives a plurality of clock signals and generates a plurality of peak signals corresponding to rising edges of the plurality of clock signals. The clock determining part determines a normal mode and an abnormal mode based on a number of the plurality of peak signals. The switches blocks outputs of the plurality of clock signals in the abnormal mode.
