Mirror Display Recess Layout for Bright Low-Power Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mirror displays in applications like the automotive sector face challenges in achieving sufficient brightness while maintaining low power consumption and a good mirroring function, often requiring higher power consumption and thermal load due to the need for increased brightness.
Innovation Solution
A mirror display design featuring a mirror surface with recesses for optoelectronic components, such as μ-LEDs, which allows for high intensity and visibility in bright environments with reduced power consumption, without compromising the mirror function, by arranging pixels in a matrix with small recesses that do not significantly affect the mirror's continuous surface appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional partially transparent mirrors are used to integrate a display, then the display can be visible, but the power consumption and thermal load increase significantly
Solution Approach 1:
The mirror surface is segmented into multiple small recesses that accommodate individual optoelectronic components (μ-LEDs). Each recess is a discrete opening in the mirror layer, allowing the display to be composed of many small light-emitting elements rather than a continuous backlight, thereby reducing overall power consumption while maintaining visibility
Solution Approach 2:
The optoelectronic components are positioned only in specific localized recesses within the mirror surface rather than requiring the entire mirror to be transparent. This localized approach allows light emission only where needed for display pixels, reducing total energy consumption compared to conventional transparent mirrors that require uniform backlighting across the entire surface
2Illumination intensity
If the display brightness is increased to ensure visibility in bright surroundings, then the display becomes clearly legible, but the thermal load and power consumption increase
Solution Approach 1:
The display is segmented into individual μ-LED components that can be precisely controlled. By using many small discrete light sources instead of a continuous high-power backlight, the system achieves required brightness through cumulative effect of multiple low-power elements, thereby reducing thermal load
Solution Approach 2:
The invention changes the physical parameters of the light-emitting components by using μ-LEDs (micro-scale LEDs) with specific optical characteristics. These micro-components have different efficiency and thermal properties compared to conventional LED backlighting, enabling high brightness output with reduced thermal generation
3Adaptability or versatility
If optoelectronic components are placed on the mirror surface, then the display function is achieved, but the continuous mirror surface is disrupted
Solution Approach 1:
The mirror layer is segmented into multiple small recesses that are distributed across the surface. Each recess is a localized discontinuity that houses an optoelectronic component, but the overall continuity of the mirror surface is preserved because the recesses are small and spaced apart, allowing the mirror to maintain its reflective function in areas between the recesses
Solution Approach 2:
The mirror surface has different local properties: areas with recesses provide display functionality while areas without recesses maintain pure mirror functionality. This local differentiation allows the same surface to serve dual purposes - reflection in most areas and light emission in specific localized regions, thereby preserving overall surface continuity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables a mirror display that maintains high brightness and low power consumption, with minimal impact on the mirror function, achieving a balance between display functionality and mirroring efficiency.
Implementation Method 1
A second plurality of optoelectronic components is disposed on a drive layer... By using μ-LEDs, a very high intensity can be achieved on a small area
Implementation Method 2
a mirror surface comprising a mirror layer having a first plurality of spaced apart recesses... The recesses do not create a mirror with a continuous surface, but rather a mirror matrix

AI summary
A mirror display includes a mirror surface having a mirror layer with a first plurality of spaced apart recesses. The mirror display also includes a second plurality of optoelectronic components disposed on a drive layer having at least leads for driving the optoelectronic components. The mirror layer is arranged in an electrically insulated manner on the drive layer. In a top view of the mirror surface, in each case at least one optoelectronic component of the second plurality is arranged in a recess of the first plurality, the emission surface of which projects beyond the mirror surface.
