Abstract: A display device includes a data driver, a multiplexer, and a multiplexer controller. The data driver outputs a data voltage through output buffers. The multiplexer distributes each of the data voltages output by the output buffers to data lines in a time division manner in response to first to control signals. The multiplexer controller sequentially outputs control signals in a time division manner. Each control signal transitions to a gate ON voltage during a prior horizontal period and maintains the gate ON voltage for an intended horizontal period.

Abstract: A method for repairing and inspecting a display device include transferring a light-emitting element onto the panel substrate; positioning the inspection substrate on the panel substrate such that the contact pins of the inspection substrate face the light-emitting element; connecting the contact pins to the light-emitting element and applying a voltage to the contact pins to identify whether or not the light-emitting element emits light and thus is defective or normal; upon determination that the light-emitting element is defective, replacing the defective light-emitting element with a normal light-emitting element; and connecting a wiring electrode to the normal light-emitting element.

Abstract: A display device includes a display panel, a data driver, a multiplexer, and a multiplexer controller. First to fourth color subpixels are disposed on the display panel. The data driver outputs a data voltage to be supplied to the first to fourth color subpixels, through output buffers. The multiplexer distributes each of data voltages output by output buffers to four data lines in a time division manner in response to first to fourth control signals. The multiplexer controller sequentially outputs a first control signal to an nth control signal during a first horizontal period, and sequentially outputs the nth control signal to the first control signal during a second horizontal period. The first and second horizontal periods include first to fourth scan periods which are continuous and uniform, and a subpixel receiving a data voltage output during the first scan period of the first horizontal period and a subpixel receiving a data voltage output during the first scan period of the second horizontal period are subpixels of the same color.
