Display Device Optical Structure for Exterior-Matched Hidden Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices suffer from specular reflection light that reduces visibility, and existing anti-reflection and anti-glare coatings fail to completely eliminate reflected light and glare, leading to a suboptimal viewing experience akin to paper-based materials.
Innovation Solution
A display device with an optical structure layer comprising an anti-glare layer and an anti-reflection layer, designed to have a gloss difference and color difference with the exterior unit of less than 10 GU and 3, respectively, allowing for a hidden display mode that mimics the texture of the exterior unit and a normal display mode with image information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If anti-reflection coating and anti-glare coating are applied to the display device, then the reflected light and glare are reduced, but the visibility is still insufficient and the viewing experience cannot be comparable to paper-based materials
Solution Approach 1:
The patent applies a composite optical structure consisting of multiple functional layers: an anti-glare layer with micro凹凸 structures for diffuse reflection, an anti-reflection layer with specific refractive index for reducing specular reflection, and a polarization layer for controlling light polarization state. This multi-layer composite structure works synergistically to achieve superior light control compared to single-layer coatings, significantly reducing both specular and diffuse reflection to match paper-based material appearance.
2Stability of the object's composition
If the display device is made to blend with the exterior unit in hidden display mode, then the aesthetic integration is improved, but the display functionality must be temporarily suspended
Solution Approach 1:
The patent implements a dynamic display system that can switch between multiple operational states: a normal display mode for showing information, and a hidden display mode where the display content matches the exterior unit's color and texture. The controller dynamically adjusts the display panel's output based on environmental light sensing and user input, enabling the display surface to adapt its appearance in real-time. This dynamic capability allows the display to blend seamlessly with the exterior unit when needed while maintaining full display functionality when required.

AI summary
A display device is used to be accommodated in an exterior unit having at least a first color, and has a hidden display mode and a normal display mode. The display device includes a display panel and an optical structure layer. The optical structure layer is disposed on the display panel and includes an anti-glare layer and an anti-reflection layer disposed on the anti-glare layer. The gloss difference between the optical structure layer and the exterior unit is smaller than 10 GU. When in the hidden display mode, the display device displays at least a second color, and the color difference between the second color and the first color is smaller than 3, and when in the normal display mode, the display panel displays an image information.
