The invention relates to a method for adjusting the luminance of at least two subpixel units (S1, Sn, S1', Sn'), wherein each subpixel unit (S1, Sn, S1', Sn') comprises at least one subpixel (R, G, B, R1, G1, B1, R2, G2, B2) of a pixel (P) of an active matrix organic light-emitting diode (AMOLED) display. The AMOLED display comprises public mode subpixel units (S1, Sn) configured for display in a public mode and privacy mode subpixel units (S1', Sn') configured for display in a privacy mode. For each subpixel unit (S1, Sn, S1', Sn'), a relative luminance loss (ΔL) is determined with respect to an initial luminance of the respective subpixel unit (S1, Sn, S1', Sn'). The most degraded subpixel unit (S1, Sn, S1', Sn') is determined as the subpixel unit (S1, Sn, S1', Sn') with the highest relative luminance loss (ΔL).If the relative luminance loss (ΔL) of the most degraded subpixel unit (S1, Sn, S1', Sn') exceeds a loss limit (G, G'), a dimming factor less than or equal to 100 percent is determined for each subpixel unit (S1, Sn, S1', Sn') such that the normalized luminance (LN) of the respective subpixel unit (S1, Sn, S1', Sn') multiplied by the dimming factor is equal to the normalized luminance (LN) of the most degraded subpixel unit (S1, Sn, S1', Sn'), but at least equal to a predetermined normalized luminance limit (LNG, LNG1, LNG2). Each subpixel unit (S1, Sn, St, Sn') is driven with a gray value and / or drive current adapted according to the respective dimming factor. If the relative luminance loss (∆L) of the most degraded subpixel unit (S1, Sn, S1', Sn') does not exceed the loss limit (G, G'), no subpixel unit (S1, Sn, S1', Sn') is adjusted with a dimming factor.

The invention relates to a method for adapting the luminance of at least two sub-pixel units (S1, Sn, S1', Sn'), wherein each sub-pixel unit (S1, Sn, S1', Sn') comprises at least one sub-pixel (R, G, B, R1, G1, B1, R2, G2, B2) of a pixel (P) of an active matrix organic light emitting diode (AMOLED) display. The AMOLED display comprises public mode sub-pixel units (S1, Sn) which are configured for a display function in a public display mode and privacy mode sub-pixel units (S1', Sn') which are configured for a display function in a privacy display mode.

Each sub-pixel unit (S1, Sn, S1', Sn') is controlled by means of a grey value and / or control current which is adapted according to the respective dimming factor.
