Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices exhibit color variation when viewed from different angles due to light refraction, leading to inconsistent image perception.
Innovation Solution
Incorporating an input sensor with an optical pattern on the display panel, featuring a first conductive layer, a first insulating layer with optical patterns, and a second conductive layer, which refracts light to minimize color variation by altering the optical path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light is emitted from the display panel in multiple directions, then the display device can be viewed from different angles, but color variation occurs due to light refraction
Solution Approach 1:
The patent introduces an optical pattern layer as an intermediary component between the display panel and the external environment. This layer includes microlens arrays, diffraction gratings, or reflective patterns that mediate the light emission process, controlling the optical path and refraction characteristics to maintain color consistency across different viewing angles while preserving wide-angle visibility
Solution Approach 2:
The optical pattern layer applies different optical properties to different regions or directions of light emission. By locally modifying the refractive index, lens shape, or reflective characteristics in specific areas of the display panel, the system optimizes light control for each viewing zone, ensuring color accuracy is maintained across the entire angular range
