Display Color Layer for Off-State Aesthetics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses appear unattractive when in a display-off state, as they only show a black color, which can negatively impact the aesthetic impression of electronic devices.
Innovation Solution
Incorporating a color layer within the display apparatus that can expose a designated color to the outside, even when the pixels are not operating, enhancing the outward appearance by allowing the display to maintain a color in both on and off states, and utilizing a pattern-formation layer to refract light and add texture to the displayed color.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a conventional display apparatus is used without a color layer, then the device structure remains simple and manufacturing cost is low, but the display apparatus appears unattractive when in a display-off state showing only black color
Solution Approach 1:
The color layer is integrated within the existing display structure, nested between the pixel layer and window layer. This allows the color layer to be incorporated without adding external components, maintaining structural compactness while achieving the aesthetic improvement of displaying designated colors in off-state
Solution Approach 2:
The color layer serves multiple functions: it provides the designated color appearance in off-state, maintains display functionality in on-state, and can be integrated with existing pixel structures. This multi-functionality resolves the contradiction by achieving aesthetic improvement without proportionally increasing device complexity
2Shape
If a color layer is added to the display apparatus, then the display can show a designated color in off-state improving aesthetics, but the device structure becomes more complex
Solution Approach 1:
The color layer is selectively applied only in specific regions where aesthetic improvement is desired, such as the black matrix areas or specific pixel regions. This localized approach allows aesthetic enhancement without uniformly increasing complexity across the entire display structure
Solution Approach 2:
The color layer is nested within the existing display stack between the pixel layer and window layer, utilizing available space rather than adding external components. This nesting strategy achieves aesthetic improvement while minimizing structural complexity increase
3Shape
If a pattern-formation layer is added to refract light, then light refraction and texture effects are achieved enhancing appearance, but the device structure and manufacturing complexity increase
Solution Approach 1:
The pattern-formation layer is merged with the color layer or integrated into the existing display stack, combining multiple functions (color display and light refraction) into a unified structure. This reduces the number of separate components and minimizes manufacturing complexity while achieving the desired visual texture effects
Solution Approach 2:
The pattern-formation layer is nested within the display structure, utilizing the vertical space between existing layers. This nesting approach achieves light refraction and texture effects without adding external components, thereby limiting the increase in device complexity
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 a superior outward appearance design by maintaining a desired color even when the display is not in use, improving the aesthetic impression and potentially reducing color distortion due to ambient illuminance.
Implementation Method 1
configured to allow a designated color to be exposed to an outside through the window layer when the at least one pixel does not operate
Implementation Method 2
a pattern-formation layer configured to refract light reflected by the color layer
