Dynamic Window Substrate for Display Device Icon Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices with embedded touch panels have input icons that are always perceivable by users, regardless of the device's operational state, which can be distracting and unnecessary when the device is in an off-state.
Innovation Solution
A window substrate with a base substrate, a light shielding layer having openings, and a filter layer that transmits light only when the device is in a specific operational mode, allowing input icons to be visible only when the device is active, using a combination of light-blocking and light-transmitting particles to control visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If input icons are always visible on the display device, then user accessibility and ease of operation are improved, but visual distraction and aesthetic quality during off-states deteriorate
Solution Approach 1:
The window substrate dynamically changes its light transmission properties based on the display device's operational state. During off-state, the substrate blocks light to hide input icons, while during active state, it transmits light to make icons visible, thus adapting to different operational conditions to resolve the contradiction between constant accessibility and state-dependent visual distraction
Solution Approach 2:
The optical parameters of the window substrate are changed based on the display state. By adjusting light transmission characteristics - from blocking to transmitting - the substrate controls the visibility of input icons, enabling them to be hidden during off-state to reduce distraction while remaining accessible during active state
2Object-affected harmful factors
If a light shielding layer with openings is used to control icon visibility, then visual distraction during off-state is reduced, but manufacturing complexity increases
Solution Approach 1:
The window substrate employs a composite structure combining a base substrate, light shielding layer with openings, and filter layer. This composite material approach enables controlled light transmission properties that hide input icons during off-state while maintaining relative manufacturing feasibility through standardized layering techniques
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 ensures that input icons are only perceivable by the user when the display device is in a specific mode, enhancing user experience by minimizing distractions and improving aesthetics during off-states.
Implementation Method 1
a filter layer on the base substrate and facing the opening, the filter layer being adapted to transmit a portion of a light passing through the opening
Implementation Method 2
a light shielding layer on the base substrate and facing at least one portion of the non-display region, the light shielding layer having at least one opening
Implementation Method 3
The filter layer may include a plurality of first particles adapted to block the incident light and a plurality of second particles adapted to transmit the incident light
