摘要： A head-up display for a vehicle having a window. The head-up display comprises a picture generating unit and a projection engine. The picture generating unit is arranged to output pictures. Each picture comprises a first picture component and a second picture component. The projection engine is arranged to receive the pictures output by the picture generating unit and project the pictures onto the window of the vehicle in order to form a first virtual image of the first picture component at a first virtual image distance and a second virtual image of the second picture component at a second virtual image distance. Light of the first picture component is polarised in a first polarisation direction and light of the second picture component is polarised in a second polarisation direction perpendicular to the first polarisation direction. The projection engine comprises an optical element having first optical power in the first polarisation direction and second optical power in the second polarisation direction such that the first virtual image distance is not equal to the second virtual image distance. The projection engine is further arranged such that the first virtual image and second virtual image at least partially overlap.
