ABSTRACT:
A flush-fitted instrument cluster for a motor vehicle includes a first display device, a second display device, and a reflecting optical combination device. The first display device (2) displays a first image located in a direct field of vision (3) of a viewer. The first image includes a background surface area (2c). The second display device (4; 40, 41) is arranged at an angle to the first display device (2) and displays a second image including a background surface area (40a,42a;41a,43a). The reflecting optical combination device (5) selectively displays the second image in the field of vision (3) of the viewer with the first image. The first image and the second image are not completely overlapping in the field of vision (3) of the viewer to form an overlapping surface area (40a,41a) and non-overlapping surface area (42a,43a). When the background surface area (40a,42a;41a,43a) of the second display device (4; 40, 41) and the background surface area (2c) of the first display device (2) have varying degrees of luminance between the overlapping surface area (40a,41a) and the non-overlapping surface area (42a,43a), at least one of transparency and brightness of the non-overlapping surface area (42a,43a) is adjusted to minimize an unwanted jump in brightness.
