Lens Component Frame Region Refraction for Display Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for reducing the frame size of display panels are approaching physical limits, and existing pseudo frame-size reduction techniques using lens components are insufficient for achieving further size reduction in response to the trend of smaller electronic units.
Innovation Solution
A display design that incorporates a lens component with a lens function section on its viewing surface side, where the visible outline of the lens component is positioned outside the frame region of the display panel, allowing display light to be refracted and directed closer to the viewer, effectively reducing the perceived frame size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a lens component is disposed on a viewing surface side of a display panel to achieve pseudo frame-size reduction, then the perceived frame size is reduced, but the visible outline of the lens component may interfere with the display quality and create visible artifacts
Solution Approach 1:
The patent applies local quality by providing the lens function section only in the circumferential region of the lens component, while the central region maintains different optical properties. This localized lens function redirects light from the frame region edges without affecting the central display area, achieving frame-size reduction while preserving overall display quality.
Solution Approach 2:
The patent segments the lens component into distinct functional regions: a lens function section in the circumferential region for redirecting frame light, and a non-lens central region for normal display. This segmentation allows each region to perform its specific function optimally without interfering with the other.
2Ease of manufacture
If the visible outline of the lens component is positioned inside the frame region, then manufacturing is simplified, but the frame size reduction effect is insufficient and dark regions remain visible
Solution Approach 1:
The patent positions the visible outline of the lens component outside the frame region in the lateral dimension, while the lens function section is strategically placed only in the circumferential region. This dimensional arrangement allows the optical function to extend beyond the frame boundaries for better frame-size reduction, while the localized lens function prevents visible artifacts.
3Length of stationary object
If the lens component covers the entire frame region, then frame-size reduction is maximized, but the complexity of the device increases and manufacturing becomes more difficult
Solution Approach 1:
The patent reduces device complexity by providing the lens function section only in the circumferential region rather than uniformly across the entire lens component. This localized approach achieves effective frame-size reduction at the critical edge areas while simplifying the overall lens structure and manufacturing process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances the pseudo frame-size reduction function, allowing display light to readily reach the viewer, thereby achieving a smaller frame size than previous methods and improving image quality by minimizing the visibility of dark regions.
Implementation Method 1
display light emitted from the effective display region is changed in an optical path by the lens function section of the lens component
