Panel Light-Control Unit for Stray-Light Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face issues with light beams emitted at various angles affecting image quality, particularly in vehicles where large-angle light beams can be reflected by windshields, causing stray light that distracts drivers.
Innovation Solution
An electronic device with a panel and a light control unit that includes a first light-emitting region and a transparent region, where the light control unit is disposed to adjust the angle of light beams, using materials like liquid crystal or light-shielding elements to suppress specific light directions, thereby reducing stray light reflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a display panel emits light beams at various angles to ensure comprehensive viewing coverage, then viewing angle is improved, but stray light reflection increases affecting image quality
Solution Approach 1:
The patent applies local quality by introducing a light control unit specifically at the edge region of the display panel where large-angle light beams are emitted. This localized approach allows the edge region to have different optical properties (light suppression capability) compared to the center region, thereby reducing stray light reflection without compromising the overall viewing angle coverage of the display panel.
Solution Approach 2:
The light control unit acts as an intermediary element between the display panel and the external environment. It is disposed at the edge region to intercept and control large-angle light beams before they can cause stray light reflection, effectively mediating the conflict between wide viewing angle and stray light reduction.
2Object-affected harmful factors
If a light control unit is added to suppress large-angle light beams, then stray light reflection is reduced, but device complexity increases
Solution Approach 1:
The light control unit is segmented into multiple independent light-shielding elements arranged at the edge region of the display panel. This segmentation allows the complex function of stray light suppression to be divided into simpler individual elements, making the overall system more manageable and easier to manufacture while achieving the desired optical control.
Solution Approach 2:
By localizing the light control unit only at the edge region rather than across the entire display panel, the patent reduces the overall complexity compared to a full-panel solution. The light control unit is strategically positioned only where large-angle light beams are emitted, minimizing the number of components needed while effectively addressing stray light reflection.
