A composite panel includes first and second substrate layers, first and second patterned electrically conductive layers, and an insulating layer. A first capacitive sensing element with a first supply line structure is formed in the first electrically conductive layer and a second capacitive sensing element with a second supply line structure is formed in the second electrically conductive layer. The first and second patterned electrically conductive layers are separated from one another by the insulating layer. The assembly composed of the first and second patterned electrically conductive layers and the insulating layer is arranged between the first and second substrate layers. The first and second capacitive sensing elements are arranged offset relative to each other. An overlap of elements of the first capacitive sensitive element and of the first supply line structure makes up an area less than or equal to 10% of that of the second capacitive sensitive element.

A switchable optical device is provided having a first substrate (11), a second substrate (12) and a seal (114). The two substrates (11, 12) and the seal (114) are arranged such that a cell having a cell gap is formed and a switchable medium (10) is located inside the cell gap. The first substrate (11) has a first transparent electrode (21) and the second substrate (12) has a second transparent electrode (22). The electrodes (21, 22) are facing towards the cell gap. The two substrates (11, 12) are arranged such that the first substrate (11) has a first region (71) adjacent to a first edge (41) of the first substrate (11) which does not overlap with the second substrate (12) and the second substrate (12) has a second region (72) which does not overlap with the first substrate (11). A first electrically conducting busbar (31) is arranged in the first region (71) and a second electrically conducting busbar (32) is arranged in the second region (72). A first terminal is electrically connected to the first busbar (31) and a second terminal is electrically connected to the second busbar (32). The first substrate (11) and the second substrate (12) each have an edge deletion (116) in which the respective transparent electrode (21, 22) is removed. The edge deletion (116) is complete on the edges non-adjacent to a busbar (31, 32) and there is no edge deletion or only partial edge deletion on edges adjacent to a busbar (31, 32). Further aspects of the invention relate to a method for designing a switchable optical device, a method for driving a switchable optical device, a method for manufacturing a switchable optical device and a system comprising a switchable optical device and a controller for driving the switchable optical device.

The trend towards increasing the glazed area in automobiles has reduced the potential locations for mounting cabin lighting. This is especially true for vehicles having large panoramic glazing. Attempts to utilize integrated light sources within the glazing have had mixed results. Embedded LEDs in the laminate tend to be too bright for night driving. Edge feed illumination with light dispersing elements on the glass to date have only been able to provide low intensity levels. Both approaches tend to reduce visibility and aesthetics in the off state. The current invention provides a means and a method to produce a laminate which provides bright cabin lighting without compromising the function of the glazing to serve as a window, by creating a light dispersing layer that is substantially invisible when in the off state and very bright in the on state.
