Display Device Background Section with Openings for Environmental Blending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices, such as liquid crystal and organic EL displays, become conspicuous black screens when not in use, failing to harmonize with their housings or surroundings, especially in environments with white walls or furniture.
Innovation Solution
Incorporating a background section with multiple openings on the front surface of the display device, allowing light from the display section to pass through, which is decorated to match the environment, thereby avoiding a black screen appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If polarizers are attached to the screen surface to enable image display, then image display functionality is achieved, but the screen becomes a black screen while not in use, which is conspicuous and does not harmonize with the housing or surroundings
Solution Approach 1:
The patent combines the polarizer layer with a decorative pattern layer to create a unified structure. The decorative patterns are formed directly on the polarizer layer, merging the functional optical component with the aesthetic element, so that when the display is off, the decorative patterns are visible through the polarizer, harmonizing with the housing and surroundings.
Solution Approach 2:
The patent applies decorative patterns only to specific regions of the polarizer layer, creating local aesthetic variations. The patterns are strategically placed in areas visible when the display is off, while maintaining the optical performance of the polarizer in the patterned regions. This allows different parts of the screen to have different visual characteristics depending on the display state.
2Adaptability or versatility
If electrochromic mirrors are provided on the front surface to function as mirrors when images are not displayed, then the black screen effect is reduced, but the device complexity increases and the screen does not completely blend with surroundings
Solution Approach 1:
The patent extracts the aesthetic function from a separate mirror component and integrates it directly into the polarizer layer. By forming decorative patterns on the polarizer itself, the invention eliminates the need for additional electrochromic mirror layers, control circuits, and power consumption associated with active mirror systems, while achieving the same aesthetic blending effect.
Solution Approach 2:
The patent uses simple, static decorative patterns formed on the polarizer layer instead of complex, active mirror systems. These patterns are essentially permanent features of the display structure, requiring no additional power, control electronics, or complex mechanisms, thereby significantly reducing device complexity and cost.
3Object-affected harmful factors
If the screen is made to reflect surrounding environment as a mirror, then the black screen is less conspicuous, but the screen is not completely blended with the surroundings
Solution Approach 1:
The patent employs decorative patterns with various colors, textures, and designs that can be customized to match different housing colors and environmental settings. These patterns are visible when the display is off, allowing the screen to visually blend with the housing and surroundings. The patterns can be designed to reflect or contrast with the surrounding environment, providing aesthetic harmony without requiring active mirroring.

AI summary
Provided is a technique allowing a screen of a display device to be harmonized with a housing of the display device or an environment surrounding the display device, while an image is not displayed. A display device (1) includes: a display section (2) which displays an image; and a background section (3) which is provided on a front surface side of the display section (2), the background section (3) having a plurality of openings (4) through which light, emitted from the display section (2) for display of the image, passes.
