FIELD: information technology. ^ SUBSTANCE: invention discloses a circuit and a method of displaying at least a first and a second image. The circuit includes at least one light source (120, 121, 220, 320, 321) configured to generate light, having at least a first and a second light characteristic and at least an element (122, 123, 223, 322, 323) for generating the first and the second image, which is configured to display the first and the second image (128, 129, 230, 231), respectively. The element (122, 222, 322) for generating the first image is at least sensitive to light, having a first light characteristic. The element (123, 223, 323) for generating the second image is at least sensitive to light, having a second light characteristic. ^ EFFECT: easier use of human-machine interface. ^ 12 cl, 6 dwg |
