Abstract: A display device includes pixels-arranged in an array with rows and columns, column lines, each connected to the pixels of one of the columns, row lines, each connected to the pixels of one of the rows, and a control unit connected to the column lines and the row lines. The control unit is configured to generate a column pulse for a selected one of the column lines and generate a data signal for a selected row line from the row lines. The data signal includes a set pulse which, when the pixel is set to a radiating state, is applied at least in part to the pixel connected to the selected column and row line when the column pulse is applied to the pixel, and drives the pixel such that a light emission of the pixel depends on the time offset between the column pulse and the set pulse.
