Abstract (en)

It is disclosed a display device (10) comprising a control unit (16) and a plurality of pixel units (20), each pixel unit comprising: input means for receiving a driving voltage transmitted by said control unit (16), a first memory element (22) operatively connected to said input means for storing a driving voltage value, a regulating unit (21, 31) operatively connected to said first memory element (22) for regulating a light in function of a driving voltage value stored by said first memory element (22). Input means comprises a second memory element (23) for storing a second driving voltage value and first switching means (24) for transferring said second driving voltage value to said first voltage value. The control unit (16) is adapted to control simultaneously the first switching means of said plurality of pixel units, so as to transfer simultaneously for each pixel unit of said plurality said second driving voltage to said second memory element.
