Luminous Panel with Light-Guiding Joint for OLED Visual Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional luminous walls using OLEDs exhibit visual discontinuities at junction zones between panels, degrading their appearance when lit, due to non-emitting intermediate zones between juxtaposed OLED devices.
Innovation Solution
A luminous panel design featuring juxtaposed OLED devices with luminous joint forming means at the back or flush with the front face, ensuring visual continuity and minimal luminance difference between emitting and intermediate zones, using reflective surfaces or light-emitting strips to redirect light and maintain uniform appearance in both 'on' and 'off' states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple OLED devices are juxtaposed to form a luminous wall, then the luminous area is increased, but visual discontinuities and intermediate dark bands appear at junction zones
Solution Approach 1:
A light-guiding element is introduced as an intermediary component between adjacent OLED devices. This element captures light from the OLEDs and redirects it into the intermediate zones, effectively mediating the visual discontinuity problem while preserving the benefit of multiple juxtaposed devices
Solution Approach 2:
The solution moves from a two-dimensional planar arrangement to a three-dimensional structure by positioning the light-guiding element vertically between OLED devices. This dimensional transition allows light redirection without compromising the flat front face appearance
2Stability of the object's composition
If junction zones are filled with conventional gap-filling systems, then structural continuity is improved, but visual discontinuities and dark bands persist in the 'on' state
Solution Approach 1:
The light-guiding element serves as an optical intermediary that transfers light from emitting zones to intermediate zones, resolving the luminance uniformity issue without interfering with the structural gap-filling function
Solution Approach 2:
The invention applies different functions to different zones: the conventional gap-filling system handles structural continuity while the light-guiding element handles optical uniformity, with each component optimized for its specific local function
3Area of stationary object
If the luminous panel uses multiple juxtaposed OLED devices, then the luminous area is increased, but intermediate dark bands degrade the appearance
Solution Approach 1:
The intermediate zones, which would normally be harmful dark bands, are converted into beneficial light-redistributing regions. The light-guiding elements transform these previously harmful zones into active light transport channels that improve overall luminance uniformity

Function Achieved in This Case
The solution provides a visually continuous and uniform luminous panel that maintains appearance consistency when OLED devices are on or off, with relative luminance and color differences minimized, enhancing the aesthetic and functional integration of luminous walls as both structural elements and lighting sources.
Implementation Method 1
organic light-emitting diodes (OLEDs), which OLEDs are able to convert electrical energy into radiation
Implementation Method 2
luminous joint forming means that ensure, when the two OLED devices are in the 'on' state, visual continuity between the intermediate zone and the two emitting zones

AI summary
A luminous panel includes at least two juxtaposed OLED devices that form a front face of the luminous panel and define two light-emitting zones separated by an intermediate zone, and a luminous joint forming mechanism that ensures, when the two OLED devices are in an on state, visual continuity between the intermediate zone and the two emitting zones, the luminous joint forming mechanism being located at a back of or flush with the front face of the panel.
