Power-free optical edge-light system for edge lighting and display extension of displays

Abstract

A power-free optical edge-light system for edge lighting and display extension of displays, characterized in that an optical structure is arranged at the edge of a display, which passively couples in display light and / or ambient light, guides it in the material and couples it out again as edge light, effect layer or functional display, without electrical energy, without electronics and without software.

Description

1. Technical field

[0001] The invention relates to a power-free optical system for edge lighting and display extension on display devices.

[0002] The system operates without electrical energy, electronics, and software, instead utilizing existing display light and / or ambient light already present during the operation of the device. 2. State of the art

[0003] Particularly well-known are: • Displays with an inactive border area between the active image area and frame elements • Solutions where edge effects are created solely through active pixels, electronics, or additional lighting. • Systems that require electricity, electronics, or software

[0004] However, no system is known that: 1. Produces visible edge light or edge display effects without power 2. Works exclusively passively, without electronics and without software, 3. Optically captures display light or ambient light, guides it within the material, and selectively emits it at the edges. 4. Technical Problem

[0005] Modern displays have an inactive border area between the active image area and the frame elements.

[0006] This area remains unused and leads to disadvantages, in particular: • The border area cannot generate any additional visible information or edge effect. • Hard display edges remain visually dominant • Extending the perceived edge effect usually requires additional electrical systems 4. Solution of the invention

[0007] The invention provides a power-free optical edge-light system that is positioned at the edge of the display.

[0008] The system captures display light and / or ambient light, passively couples this light into an optical medium, guides it within the medium, and couples it out again at the edge as edge light, effect layer, or function display.

[0009] The system works purely optically and requires no electrical energy, no electronics, and no software. 5. Designs

[0010] The execution can be carried out in particular as: • optical edge component located at the edge of the display • Transparent or translucent optical element with a light-guiding structure • optical structure with microstructures for light guidance, light distribution and / or diffuse emission • Layer structure consisting of transparent layers with light-guiding area and extraction zone • Design as a module, clip, frame, attachment or insert element. The design can be material-integrated, for example as a plastic component, film, insert, frame or edge structure. 6. Operating principle

[0011] The operating principle is based on: • passive light coupling from display light and / or ambient light • light-guiding guidance in the material • defined extraction at the edge as edge light, effect layer or function display • Optional diffusion or scattering for visible, uniform edge coverage 7. Fastening

[0012] The system can be attached to the display, in particular by: • Clip attachment to the edge of the display • Clip-on or plug-in design in existing frame areas • Frame element around the display • Insert between display and cover or housing • magnetic holding elements • Guide rails or positive-locking retaining elements 8. Advantages

[0013] Passive edge lighting or edge display emission creates a visible edge effect without the need for additional electrical systems.

[0014] The system can be designed modularly and adapted to different display designs.
