Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices struggle to control viewing angles and minimize power consumption, particularly in vehicle applications where content visibility needs to be adjusted to avoid distracting the driver.
Innovation Solution
A display device with a display panel divided into areas of different pixel densities and viewing angles, utilizing light emitting diodes and optical members to control the viewing angle and luminance, allowing for both wide and narrow viewing angles with minimized boundary visibility and reduced power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display panel uses a single wide viewing angle configuration, then the viewing angle is improved, but the power consumption increases due to increased luminance requirements
Solution Approach 1:
The display panel is divided into first and second areas with different pixel densities and viewing angle characteristics. The first area has higher pixel density and wider viewing angle, while the second area has lower pixel density and narrower viewing angle, allowing each region to be optimized for its specific function rather than the entire panel using uniform high-performance specifications
Solution Approach 2:
The display panel is segmented into distinct functional areas (first area for wide viewing angle content, second area for narrow viewing angle content) with different pixel densities and optical member configurations, enabling independent optimization of each segment for its intended purpose
2Ease of operation
If the display panel increases luminance to maintain visibility at wide viewing angles, then the viewing angle is improved, but the power consumption increases
Solution Approach 1:
Different areas of the display panel use different pixel densities and optical member types to achieve appropriate viewing angles without requiring uniform high luminance across the entire panel, thereby reducing overall power consumption while maintaining visibility where needed
3Use of energy by moving object
If the display panel uses different pixel densities in different areas, then the power consumption is reduced, but the visibility of the boundary between areas increases
Solution Approach 1:
Optical members with different viewing angle characteristics are used in different areas to create visual differentiation between the first and second areas, making the boundary visible through optical properties rather than requiring abrupt physical transitions or additional structural elements
