    Abstract: The object of the invention relates to a patterned edge-illuminated display (100) for use in the examination of visual evoked potentials with simultaneous MR imaging, comprising at least two plates, a first plate (110) and a second plate (120), wherein the first plate (110) and the second plate (120) are transparent, internally reflective light transmitting plates, each of the first plate (110) and the second plate (120) has two major flat surfaces parallel to each other, and edges, a first light source (131) and a second light source (132) distributed along and optically coupled to first plate edges (113) and second plate edges (123), respectively, a light source controlling means (140) and a first plate pattern (111) applied to at least the first major surface of the first plate (110) and a second plate pattern (121) applied to at least the first major surface of the second plate (120), which are configured to extract light from the first plate (110) and the second plate (120) respectively. The display further comprises an opaque background board (150), wherein the first plate (110) and the second plate (120) are stacked on the opaque background board (150), all with edges juxtapositioned to a respective edges of each other forming a display board (105). The first plate pattern (111) is complementary to the second plate pattern (121) and the first light source (131) is distributed along all of the first plate edges (113) and the second light source (132) is distributed along all of the second plate edges (123) and the light source controlling means (140) alternately illuminates the first light source (131) and the second light source (132) such that the light is supplied only to all of the first plate edges (113) or to all of the second plate edges (123) at a time.
