Dual-Emitter Display Optics for High Resolution and Viewing-Angle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices struggle to independently control viewing angles and resolution without increasing the number of lines and pixel layout, particularly in applications like vehicle dashboards where different areas require varying viewing angles and high resolution.
Innovation Solution
A display device with a display panel divided into active and non-active areas, featuring pixels with dual light emitting elements and optical members, and selection signal generators to control each area's driving mode, allowing independent control of wide or narrow viewing angles without additional lines or pixel layout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of lines and pixel layout on the display panel is increased to achieve high resolution, then the resolution is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The display panel is divided into multiple independent control areas, with each area having its own selection signal generator. This segmentation allows independent control of different regions without requiring additional lines across the entire panel, achieving high resolution through localized pixel control while minimizing overall line complexity
Solution Approach 2:
Different areas of the display panel can have different viewing angle characteristics by controlling different light emitting elements independently. Each area can be optimized for specific viewing requirements without affecting other areas, allowing high resolution display with area-specific optical properties without increasing overall pixel count
2Adaptability or versatility
If the viewing angle is increased to provide wide viewing coverage, then the viewing angle is improved, but the image quality and resolution may deteriorate
Solution Approach 1:
The display device can dynamically switch between different viewing angle modes by controlling different light emitting elements through selection signal generators. The viewing angle characteristics can be adjusted in real-time based on user needs without permanently compromising image quality, as different areas can be activated selectively
Solution Approach 2:
Different areas of the display can provide different viewing angle characteristics simultaneously. Areas requiring wide viewing angles can be configured differently from areas requiring high image quality, allowing both requirements to be satisfied in their respective zones without mutual interference
3Adaptability or versatility
If the display panel is divided into multiple areas with independent control, then the adaptability and viewing angle control are improved, but the device complexity increases
Solution Approach 1:
Each selection signal generator is designed to be multi-functional, controlling multiple light emitting elements within its area through a unified control mechanism. This universal design allows independent area control to be achieved without requiring a separate control circuit for each individual element, reducing overall device complexity while maintaining adaptability

AI summary
A display device can include a display panel having an active area and a non-active area and having a plurality of pixels and a plurality of selection signal generators disposed on the active area, and a timing controller configured to control the display panel. Each pixel can include a first light emitting element, a first optical member configured to refract light from the first light emitting element, a second light emitting element configured to emit light of the same color as the first light emitting element, and a second optical member configured to refract the light from the second light emitting element and having a different shape from the first optical member. Each selection signal generator can control one of the first light emitting element and the second light emitting element included in at least one corresponding pixel among the pixels to emit light.
