TECHNICAL FIELD

This disclosure relates to an apparatus for presenting an image, a method of adjusting a control circuit for presenting an image, and a method of operating an apparatus for presenting an image.

BACKGROUND

It is known to use light-emitting diodes to present an image for a heads-up display. There is nonetheless a need for an improved apparatus for presenting an image for a heads-up display.

SUMMARY

We provide an apparatus for presenting an image for a heads-up display including three arrays of light-emitting diodes, wherein the light-emitting diodes of an array are arranged and output electromagnetic beams in an emission direction of an emission side of the array, the light-emitting diodes output an electromagnetic beam with a first opening angle in the emission direction, a collimation apparatus provided on the emission side at a specified spacing in front of the array of the light-emitting diodes, wherein the collimation apparatus reduces the first opening angles of the beams of the light-emitting diodes downstream of the collimation apparatus in the emission direction to a second opening angle, the second opening angle is smaller than the first opening angle, and a combination optical unit arranged downstream of the collimation apparatus in the emission direction, the combination optical unit superposes the electromagnetic rays from the three arrays to form an image for the head-up display.

We also provide a method of adjusting a control circuit for presenting an image for a heads-up display including providing at least two arrays of light-emitting diodes, wherein the light-emitting diodes of each array are individually actuable by a control circuit, and the light-emitting diodes of an array output electromagnetic beams in an emission direction of an emission side of the array, providing a combination optical unit in the emission directions of the arrays, wherein the combination optical unit superposes the electromagnetic rays of the three arrays to form an image for a heads-up display, wherein generating a test image with at least two arrays, performing a check as to whether a partial image of an array projects beyond a specified image, and, upon detecting an overlap of the partial image beyond the image, setting the control circuit of the apparatus in a way such that the light-emitting diodes that cause the overlap are not actuated.

We further provide a method of operating an apparatus for presenting an image for a heads-up display including providing three arrays of light-emitting diodes, wherein the light-emitting diodes of each array are individually actuable by a control circuit, and the light-emitting diodes of an array output electromagnetic beams in an emission direction of an emission side of the array, providing a combination optical unit in the emission directions of the arrays, wherein the combination optical unit superposes the electromagnetic rays of the three arrays to form an image for a head-up display, and causing the control circuit to actuate the light-emitting diodes of the arrays such that an overlap of a partial image of an array beyond the image is prevented.
