Abstract

The invention pertains to display method, a computer program for performing the steps of the display method and a display system ( 1 ), the display system having for example: at least one display unit ( 13, 16 ) arranged to present at least one display image, at least one memory unit ( 12, 15 ) comprising information related to for example descriptions of a set of default graphics display objects (W 1 -W 3 ) and configuration data. The configuration data is arranged to define: at least one transparent display layer (L 1 -L 3 ), at least one transparent display container (CO 0 -CO 2 ) associated to the at least one transparent display layer and at least one display mode. Each of said at least one display mode comprising a predetermined selection of one or more of said at least one transparent display container of one or more of said at least one display layer.

First claim

The invention claimed is:

1. A display system, the display system comprising:
display means comprising:
at least one display unit arranged to present at least one display image,
at least one memory unit comprising information related to (a) descriptions of a set of default graphics display objects, (b) at least one modifiable attribute of at least one default graphics display object of the set of default graphics display objects, and (c) configuration data, and
at least one processor arranged to process the information of said at least one memory unit to control the at least one display image; and

a plurality of control modules arranged to stream information related to the at least one modifiable attribute to said at least one memory unit to enable the at least one processor to update the at least one modifiable attribute,
wherein:
the display system is compliant with the Aeronautical Radio, Incorporated (ARINC) 661 specification, and
the configuration data, when processed by the at least one processor, is configured to cause display of:
one or more transparent display layers, each of said one or more transparent display layers being arranged to define a display region positioned within one or more display windows of said at least one display unit, a first transparent display layer of the one or more transparent display layers being configured to not prevent the visibility of a second display layer of the one or more transparent display layers when the first transparent display layer at least in part overlaps the second display layer, a display layer being a highest level container in a hierarchical structure of displayable entities, and
a plurality of transparent display containers, each transparent display container is associated to one or more of the one or more transparent display layers, each of the plurality of containers (a) is a container widget as defined by the ARINC 661 standard, (b) is positioned in a portion of said display region, and (c) has at least one default graphics display object of the set of default graphics display objects positioned within the portion of the display region, and

the configuration data is further configured to, when processed by the at least one processor, cause the at least one transparent display layer to be displayed in accordance with at least one display mode, each of said at least one display mode comprising a predetermined selection of one or more of said at least one transparent display container of one or more of said at least one transparent display layer to provide for each of the at least one display mode a predetermined combination of the at least one default graphics display object of one or more of the at least one transparent display container of the one or more of said at least one transparent display layer in order to form the at least one display image based on the at least one processor processing the information related to the at least one display mode.

2. The display system according to claim 1 , wherein each of said one or more transparent display containers being controllable to assume a visible or an invisible state according to the predetermined selection, wherein said visible or invisible state is arranged to affect the visibility of each of the at least default graphics display object associated to the plurality of transparent display containers being controlled.

3. The display system according to claim 1 , wherein the configuration data is arranged to define a plurality of transparent display layers.

4. The display system according to claim 1 , wherein the configuration data is arranged to define a plurality of display modes.

5. The display system according to claim 1 , wherein the at least one display mode is selectable by means of a user interface or automatically selected based on information related to current operation of a vehicle arranged to host the display system.

6. The display system according to claim 1 , wherein the at least one processor is arranged to present the at least one display image by super positioning overlapping transparent display layers and/or portions thereof, based on a predetermined layer priority scheme arranged to determine the order of visibility among the plurality of transparent display layers.

7. The display system according to claim 1 , wherein the at least one processor is arranged to present the at least one display image by super positioning overlapping transparent display containers and/or portions thereof, based on a predetermined container priority scheme arranged to determine the order of visibility among a plurality of transparent display containers associated to each of the one or more transparent display layers.

8. The display system according to claim 1 , wherein each of the one or more transparent display layers being controllable to assume a visible or an invisible state according to the predetermined selection, wherein said visible or invisible state is arranged to affect the visibility of each of the at least default graphics display object associated to each of the at plurality of display containers associated to the one or more transparent display layers being controlled.

9. The display system according to claim 1 , wherein the configuration data is arranged to define at least one predetermined graphics attribute for each of at least one first default display graphics object of the set of default graphics objects, wherein said at least one predetermined graphics attribute each being arranged to determine one or more graphics property of each of said at least one first default graphics display object.

10. The display system according to claim 9 , wherein the at least one predetermined graphics attribute comprises one or more graphics attribute selected from a group of graphics attributes comprising a colour, an outline colour, a shape and a size.

11. The display system according to claim 9 , wherein the at least one predetermined graphics attribute for each of said at least one first default graphics display object is arranged to determine the size and/or shape of each of the at least one first default graphics display object relative to a size and/or shape of one or more of the other default graphics display objects of the set of default graphics display objects such that when the configuration data is processed by the at least one processor, the set of default graphics display objects are displayed so that each default graphics display object of the set of default graphics display objects is at least partially visible irrespectively of selected display mode.

12. The display system according to claim 9 , wherein the configuration data is arranged to define the at least one predetermined graphics attribute based on a relative position of one or more default graphics display object of the set of default graphics display objects, the predetermined layer priority scheme arranged to determine at least one of an order of visibility among the plurality of transparent display layers or an order of visibility among the plurality of transparent display containers associated to each of the one or more transparent display layers.

13. The display system according to claim 8 , wherein the at least one memory unit is arranged to buffer the information streamed from the plurality of control modules that are associated to the at least one modifiable attribute of the at least one default graphics display object of the set of default graphics display objects of each of the at least one transparent display container of each of the one or more transparent display layers currently being in the invisible state.
