The invention relates to a display device and to a method of controlling a display device. A display device with a plurality of pixels arranged in rows n and columns m is presented so as to render possible an energy saving through charge sharing in the display device, in particular an active matrix display, in which the pixels can be activated via control lines (6), and with a row driver circuit (4) for driving the n rows with a row voltage (Vrow), wherein the rows of the display device can be consecutively selected from 1 to n, and with a column driver circuit (3) for driving the m columns with a column voltage (Vcol) corresponding to the picture data of the pixels (8) of the selected line to be displayed, and wherein it is provided for a transition from a selected row n to another row n+1 that the row voltage (Vrow) is connected to an intermediate voltage level (VZ), and the row n+1 is first connected to the intermediate voltage level (VZ) and subsequently is charged up to the required row voltage (Vrow).
A display device with a plurality of pixels arranged in rows n and columns m, wherein the pixels of a row can be selected through control lines, and with a row driver circuit for activating the n rows by means of a row voltage and with a column driver circuit for controlling the m columns with a column voltage, which voltages correspond to the image data of the pixels of the selected row to be displayed, and wherein it is provided upon a transition from a selected row n to another row n+x that the row voltage is connected to an intermediate voltage level, and the row n+x is first connected to said intermediate voltage level and subsequently is charged up to the required row voltage.
A method of controlling a display device with pixels arranged in rows n and columns m, wherein row voltages are supplied to the rows via control lines so as to select said rows, and wherein column voltages are supplied to the columns m via data lines, and wherein the rows are consecutively selected, and in the case of a transition from a selected row n to another row n+1 the charge applied to the selected row n is transferred to an intermediate voltage level, and the other row n+1 is first connected to said intermediate voltage level and is subsequently charged up to the required control voltage.
