Lenticular Display Distortion Correction for Slanted Edges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices using lenticular lenses suffer from distortion issues due to the optical characteristics of the lenticular lens, leading to disconnected edges and color separation phenomena in the images viewed by different viewpoints.
Innovation Solution
The display device identifies areas in the target image with similar slanted angles to the lenticular lens and applies combination values to sub-pixels within these areas to correct distortion, using predefined slanted angles and optical characteristics to adjust pixel values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lenticular lens is used to generate 3D effects and multiple images for different view positions, then the viewer can perceive three-dimensional images without glasses, but distortion occurs including disconnected edges and color separation phenomena
Solution Approach 1:
The patent applies different combination values to sub-pixels based on their local position and the local slanted angle characteristics. By identifying specific areas with slanted angles similar to the lenticular lens and applying targeted combination values to sub-pixels in those areas, the method achieves local optimization of image quality without affecting the entire display, thereby resolving the contradiction between maintaining 3D viewing capability and ensuring image quality consistency.
2Adaptability or versatility
If the lenticular lens outputs different images to different view positions (left eye and right eye), then the viewer can recognize 3D images, but distortion issues such as disconnected edges and color separation occur
Solution Approach 1:
The patent changes the output parameters of sub-pixels by applying combination values that are calculated based on the slanted angle similarity to the lenticular lens. This parameter adjustment compensates for the distortion caused by the lenticular lens, ensuring that images viewed from different positions maintain continuity and color consistency while still enabling multi-view 3D functionality.
3Manufacturing precision
If sub-pixel values are adjusted to correct distortion in areas with slanted angles similar to the lenticular lens, then image quality consistency is improved, but the processing complexity increases
Solution Approach 1:
The patent segments the display area into different regions based on the slanted angle characteristics, identifying specific areas where the slanted angle is similar to the lenticular lens. By focusing the combination value application only on these identified areas rather than the entire display, the method achieves effective distortion correction while minimizing processing complexity and avoiding unnecessary computations in areas that do not require correction.

AI summary
A method performed by a display device including a lenticular lens is provided. The method includes obtaining, by the display device, a target image, identifying, by the display device, a predefined slanted angle of the lenticular lens, identifying, by the display device, in the target image, at least one area including at least one edge having a slanted angle of which similarity to the slanted angle of the lenticular lens is within a preset range, selecting, by the display device, a plurality of sub-pixels of a same row as a first sub-pixel included in the identified at least one area, and allocating, by the display device, a first combination value to an output value of each of the plurality of sub-pixels, the first combination value being obtained by combining values of the plurality of sub-pixels.
