Transparent Display Knob with Louver Film to Suppress Edge Reflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices with a protruding transparent member experience light reflection on the outer periphery, leading to reduced visibility and diminished quality of the display surface and the transparent member.
Innovation Solution
The implementation of a louver film member between the display panel and the protruding transparent knob, which suppresses the diffusion of light towards the outer periphery, reducing light reflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a protruding member made of transparent material is provided on the display surface, then the display device achieves enhanced user interaction and aesthetic quality, but light reflection occurs on the outer periphery of the protruding member causing deterioration in visibility and quality
Solution Approach 1:
An anti-reflection film is introduced as an intermediary layer between the display panel and the protruding member. This film specifically targets and reduces light reflection at the interface, allowing the protruding member to maintain its transparent aesthetic and interactive functionality while eliminating the harmful reflection effect on visibility and quality.
Solution Approach 2:
The anti-reflection film utilizes optical property changes to reduce reflection. By modifying the refractive index and optical characteristics of the film layer, it creates destructive interference for reflected light waves, effectively reducing the intensity of reflected light and improving overall visibility without affecting the protruding member's appearance.
2Adaptability or versatility
If a protruding member is provided on the display surface, then functional interaction is enabled, but the quality and sense of luxury of the transparent member deteriorates due to light reflection
Solution Approach 1:
The anti-reflection film serves as a mediator that preserves the functional and aesthetic properties of the protruding member while eliminating the harmful reflection. It allows light to pass through clearly for visual recognition and touch interaction, while simultaneously reducing parasitic reflections that would otherwise degrade the sense of luxury and quality.
3Illumination intensity
If light emitted from the display panel enters the protruding member, then the protruding member can be visually recognized, but light is reflected by the outer periphery and emitted outside causing glare
Solution Approach 1:
The anti-reflection film converts the harmful reflection effect into a beneficial transmission effect. By designing the film with specific optical properties and thickness, it causes destructive interference for reflected light while simultaneously enhancing light transmission, thereby transforming the reflection problem into an improved visual recognition and reduced glare scenario.
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
This solution effectively minimizes light reflection on the outer periphery of the transparent knob, enhancing visibility and maintaining the quality of the display surface.
Implementation Method 1
the diffusion of the light emitted from the display surface of the display panel is suppressed by the louver film member
Implementation Method 2
a part of the light emitted from display panel X2 enters the protruding member X5 formed of a transparent material, is reflected by the outer periphery of the protruding member X5, and is emitted to the outside of protruding member X5
