DRIVING TO REDUCE AGING IN AN ACTIVE MATRIX LED DISPLAY

摘要

A driver (DD, SD, PD1, PSI, 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 (PL I) 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, PSI, PD2, PS2) controls the second duty cycle to be larger than the first duty cycle. The driver also controls the second current (I2) to be smaller than the first current (I2)
