A head-up display for a vehicle comprises an optical component having a reflective surface arranged, during head-up display operation, in a configuration that is conducive to sunlight glare. A light control layer is disposed on the optical component to receive sunlight on an optical path to the reflective surface. The light control layer comprises a sunlight-receiving surface and a core material separating an array of louvres. The sunlight-receiving surface of the light control layer is serrated in coordination with the array of louvres so as to deflect received sunlight away from the eye-box of the head-up display.

A coating device comprising a sample carrier, a source, shadow mask and coating driver. The source comprises a plurality of targets such as a first target and second target. The source is arranged to coat at least one sample housed in the sample carrier. The shadow mask is disposed in a line-of-sight between the sample carrier and source. The shadow mask is arranged such that the first target provides a first coating contribution. The shadow mask is further arranged such that the second target provides a second coating contribution. The second coating contribution is different to the first coating contribution. At least one of the first and second coating contributions is non-uniform in a first dimension of the sample. The coating driver is arranged to independently control the first coating contribution and second coating contribution such that a thickness gradient of the coating in the first direction is variable.

A display system having an eye-box or viewing window from within which image content formed by thereby can be seen. The display system comprises an image projector and a user-tracking system such as an eye-tracking system. The image projector is arranged to project a virtual image at a virtual image distance from the eye-box. In some embodiments, the image projector is arranged to project a first virtual image at a first virtual image distance and project a second virtual image at a second virtual image distance different to the first virtual image distance. The user-tracking system is arranged to try and determine an eye-box position of a user within the eye-box. The user-tracking system is further arranged to determine a corresponding confidence value or level associated with the determination. The image projector is arranged to project the virtual image at a finite virtual image distance if the confidence value is above a threshold value. The image projector is further arranged to project the virtual image at an infinite virtual image distance if the confidence value is below the threshold value.
