Abstract:
An active matrix liquid crystal display, comprising:pixels arranged in rows and columns of a matrix, each of the pixels including at least two sub-pixels, and each of the pixels being formed from at least two adjacent sub-pixel electrodes, a reference electrode being common to the pixels, and a liquid crystal layer lying between the sub-pixel electrodes and the reference electrode; row electrodes, a respective one of the row electrodes being assigned to each row of pixels; column electrodes, a respective one of column electrodes being assigned to each column of the pixels; a row control unit connected to the row electrodes and successively generating control signals for the rows of pixels; a column control unit connected to the column electrodes and generating gray-scale signals having chronologically success gray-scale levels for the sub-pixels; pixel control units individually assigned to the pixels; and controllable switches individually assigned to the sub-pixels, the sub-pixel electrodes being connected to an assigned one of the column electrodes via a respective one of the controllable switches, a control side of the respective one of the controllable switches being connected to an assigned one of the row electrodes via one of the pixel control units assigned to the sub-pixels, each of the pixel control units generating locally and chronologically different turn-on signals for the controllable switches assigned to the sub-pixels from the control signals supplied via one of the row electrodes; wherein each of the control signals includes individual, chronologically successive signal pulses, each of the pixel control units including an arrangement that converts the chronologically successive signal pulses into the locally and chronologically different turn-on signals.
