  • Publication number: 20080111799
    Abstract: A driver (DD, SD, PD1, PD2) drives a display panel which comprises a first set of light emitting elements (PL1) and a second set of light emitting elements (PL2). The driver (DD, SD, PD1, PD2) comprises a data driver (DD) which receives a first set of input image signals (R) representing a first color to supply a first set of data signals (RD 1) to the first set of light emitting elements (PL1), respectively. The data driver (DD) further receives a second set of input image signals (B) representing a second color to supply a second set of data signals (BD1) to the second set of light emitting elements (PL2), respectively. A lowpass filter (LPF) is provided to obtain the second set of data signals (BD1) having a bandwidth being smaller than a bandwidth of the first set of data signals (RD1).

  • Publication number: 20080018632
    Abstract: A driver (DD, SD, PD1, PS1, PD2, PS2) supplies, at a frame rate, a first current (I1) with a first duty cycle being smaller than one to a first light emitting element (PL1) of an active matrix display (AMD) and a second current (I2) to a second light emitting element (PL2) of the active matrix display (AMD). The second light emitting element (PL2) has a shorter lifetime than the first light emitting element (PL1). The driver (DD, SD, PD1, PS1, PD2, PS2) limits controls the second duty cycle to be larger than the first duty cycle.
