Touch Panel Light-Shielding Structure for Wear-Free Dynamic Logos
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing logo graphics on electronic devices wear off over time due to fixed structures and colors, leading to durability issues.
Innovation Solution
A touch panel design featuring a substrate with a touch layer and an annular light shielding layer that includes a light transmitting portion with an array of holes, allowing for a logo graphic to be displayed dynamically and adjustable in color, while the light shielding layer maintains a sufficient aperture ratio and hole distribution to prevent wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed structure and specific color are used for logo graphics, then the logo can be displayed clearly, but the logo will wear off after long-term use
Solution Approach 1:
The patent transforms the static, fixed logo structure into a dynamic display system. The light shielding layer with arrayed holes can be selectively illuminated to display different logo patterns, allowing the logo to be updated and changed without physical replacement, thereby eliminating wear issues from fixed structures.
Solution Approach 2:
The patent changes the display parameters of the logo by controlling the illumination of different regions of the light shielding layer. By adjusting which holes are illuminated and their brightness, various logo patterns and colors can be displayed dynamically, replacing the fixed color and structure with controllable optical parameters.
2Illumination intensity
If the light shielding layer has a high aperture ratio to allow light transmission for logo display, then the logo visibility is improved, but the light shielding performance for the touch layer may be compromised
Solution Approach 1:
The light shielding layer employs local quality differentiation by having different regions with varying light transmission properties. The arrayed holes are strategically positioned and sized to allow light transmission specifically in the logo display region while maintaining light shielding in other areas, thus achieving both logo visibility and touch layer protection.
Solution Approach 2:
The light shielding layer utilizes a porous structure with arrayed holes to achieve selective light transmission. The holes are distributed in specific patterns that allow light to pass through for logo display while the surrounding material maintains light shielding functionality, creating a balance between transparency and shielding performance.
