Each of the display panels include a plurality of multi-domain liquid crystal display cells. The processing system may be configured to display a first object on the front display panel of the plurality of display panels, display, on a display panel overlapped by the front display, a second object such that the second object is at least partially overlapped by the first object. The first and second objects are displayed according to a soft additive model, where the superposition of bright colors results in a brighter color. ## Claims ### Claim 1 An instrument panel comprising; a multi-layer display system including a front display panel and a rear display panel arranged in a substantially parallel manner, the front display panel overlapping the rear display panel, the front display panel and the rear display panel each including a plurality of multi-domain liquid crystal display cells; a backlight configured to provide light to the front display panel and the rear display panel of the multi-layer display system; and a processing system comprising at least one processor and memory, the processing system configured to: display a first object on the front display panel; and display, on the rear display panel, a second object such that the second object is at least partially overlapped by the first object. ### Claim 2 (depends on 1) The instrument panel of claim 1, wherein the front display panel and the rear display panel are multi-domain in-plane-switching liquid crystal displays. ### Claim 3 (depends on 1) The instrument panel of claim 1, wherein the front display panel and the rear display panel are triple-domain in-plane-switching liquid crystal displays. ### Claim 4 (depends on 1) The instrument panel of claim 1, wherein the first object is displayed such that at least a portion of the first object overlaps the second object displayed on the rear display panel, and at least a portion of the first object is displayed without overlapping the second object. ### Claim 5 (depends on 1) The instrument panel of claim 1, wherein relative luminance of the first object displayed on the front display panel is higher than relative luminance of the second object displayed on the rear display panel. ### Claim 6 (depends on 1) The instrument panel of claim 1, wherein the first object is of a uniform color that is different from a uniform color of the second object. ### Claim 7 (depends on 6) The instrument panel of claim 6, wherein the first object is displayed in a manner to maintain appearance of being solid and in front of the second object displayed on the rear display panel. ### Claim 8 (depends on 6) The instrument panel of claim 6, wherein the first object is displayed in a manner on the front display panel to maintain appearance of being solid and in front of the second object displayed on the rear display panel. ### Claim 9 (depends on 1) The instrument panel of claim 1, wherein the first object has a same shape and size as the second object, and the first and second objects are displayed in an overlapping manner ### Claim 10 (depends on 1) The instrument panel of claim 1, wherein the first object has a same shape and size as the second object, and the first and second objects are displayed in an overlapping manner ### Claim 11 (depends on 1) The instrument panel of claim 1, wherein the front display panel is a touch sensitive display, and the processing system is configured to detect whether a touch input is performed to a portion of the front display panel displaying the first object. ### Claim 12 (depends on 1) The instrument panel of claim 1, wherein the plurality of multi-domain liquid crystal display cells in the front display panel and rear display include a liquid crystal material disposed between a first substrate and a second substrate to form a liquid crystal cell, and a chevron shaped electrode structure including a plurality of chevron-shaped cell electrodes interleaved with a plurality of chevron-shaped common electrodes in the first substrate, wherein the interleaved plural chevron-shaped cell and common electrodes divide liquid crystal cell into a plurality of regions. ### Claim 13 A multi-layer display system, comprising: a first display and a second display arranged in a substantially parallel manner to the first display, the first display overlapping the second display, and the first display and the second display each including a plurality of multi-domain liquid crystal display cells; a light source configured to provide light to the first display and the second display; and a processing system comprising at least one processor and memory, the processing system configured to: display a first object on the first display; and display, on the second display, a second object such that the second object is at least partially overlapped by the first object. ### Claim 14 (depends on 13) The multi-layer display system of claim 13, wherein the first display and the second display are multi-domain in-plane-switching liquid crystal displays. ### Claim 15 (depends on 13) The multi-layer display system of claim 13, wherein the first and second displays are triple-domain in-plane-switching liquid crystal displays. ### Claim 16 (depends on 13) The multi-layer display system of claim 13, wherein the first object is displayed such that at least a portion of the first object overlaps the second object displayed on the second display, and at least a portion of the first object is displayed without overlapping the second object. ### Claim 17 (depends on 13) The multi-layer display system of claim 13, wherein relative luminance of the first object displayed on the first display is higher than relative luminance of the second object displayed on the second display. ### Claim 18 (depends on 13) The multi-layer display system of claim 13, wherein the first object if of a uniform color that is different from a uniform color of the second object. ### Claim 19 (depends on 13) The multi-layer display system of claim 13, wherein the first object has a same shape and size as the second object, and the first and second objects are displayed in an overlapping manner ### Claim 20 (depends on 13) The multi-layer display system of claim 13, wherein the first display is a touch sensitive display, and the processing system is configured to detect whether a touch input is performed to a portion of the front display displaying the first object. ### Claim 21 (depends on 13) The multi-layer display system of claim 13, wherein relative luminance of the first object displayed on the first display is higher than relative luminance of the second object displayed on the second display. ### Claim 22 (depends on 13) The multi-layer display system of claim 13, wherein the processing system is further configured to: in response to instructions to move the second object displayed on the second display to the first display, display the second object with a relative luminance that is higher than the relative luminance used to display the second object on the first display. ### Claim 23 (depends on 22) The multi-layer display system of claim 22, wherein the second object displayed on the first display at least partially overlaps content displayed on the first display.
