Abstract

A display control system for a multi-layer display system including at least one multi-layer display unit. A multi-layer display unit includes multiple stacked or overlapped display layers each adapted to render display elements thereon for viewing through the uppermost display layer. The level of difficulty for a user to view an overlapped image differs depending on the colour, brightness or type of images (for example text-on-text) being displayed and also the layer in which the image is being displayed and whether the image is currently active. At least any overlapping portion of display elements from different display layers are adjusted (automatically or by a user) in order to improve the viewing experience for a viewer. Types of adjustment possible include moving the images within their display layer or to an alternative display layer or altering their visual properties (such as colour, brightness, contrast, etc.).

Claims

1. A multi-layer display system comprising:

a first display and a second display, the first and second displays configured to display a first image and a second image, respectively, so that the first and second images overlap each other as viewed from a point of view of a viewer; and

a controller configured to;

move a first user interface from the second display to the first display so that after the first user interface is moved the first user interface is to be displayed on the first display and to overlap another display element that is displayed on the second display, wherein the first user interface comprises first and second adjacent sections, the first section configured to illustrate display elements displayed via the first display and the second section configured to illustrate display elements displayed via the second display, and wherein the first user interface is configured to allow a user to move a given display element from the first display to the second display by dragging and dropping that given display element from the first section to the second section of the first user interface;

adjust brightness and/or transparency of the first user interface so as to improve visibility of the first user interface and/or the another display element; and

control symbols within the first user interface located on the first display via manipulation of a pointer on the second display, so that the symbols of the first user interface can be controlled by the pointer even when the pointer is on a different display.

2. The multi-layer display system of claim 1, wherein the first and second displays each comprise a liquid crystal display.
