Abstract
A display assembly comprising a backlight unit having at least two optical waveguide elements lying alongside one another, and configured such that light is emitted with a greater brightness in a boundary region of the optical waveguide elements than outside the boundary regions, a display unit arranged such that during operation of the display assembly light emitted by the backlight unit impinges on a rear side of the display unit, a diffuser layer arranged between the backlight unit and the display unit, and a control unit that compensates for a greater brightness in the boundary regions by adapted driving of the display unit.

A display assembly comprising:
- a backlight unit having at least two optical waveguide elements lying alongside one another and configured such that light is emitted with a greater brightness in a boundary region of the optical waveguide elements than outside the boundary region;
- a display unit arranged such that during operation of the display assembly light emitted by the backlight unit impinges on a rear side of the display unit;
- a diffuser layer arranged between the backlight unit and the display unit;
- and
- a control unit that compensates for a greater brightness in the boundary region by adapted driving of the display unit.
A method for driving a display unit of a display assembly having a backlight unit, comprising:
- receiving a video signal;
- processing the video signal using a previously known brightness distribution of light emitted by the backlight unit;
- and
- driving the display unit in such a way that brightness differences of the backlight unit are compensated for.
