Liquid Crystal Display Disclination Reduction via Dynamic Image Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid crystal display technologies fail to effectively reduce disclination without deteriorating image quality, particularly for videos requiring sharpness and high brightness and contrast ratios.
Innovation Solution
A liquid crystal display apparatus that includes a processor and a corrector to selectively apply image processing techniques such as level restriction and smoothing to reduce disclination, using a liquid crystal driver to modulate the liquid crystal display element based on input image signals, allowing for adaptable correction methods depending on the type of video signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image processing methods (level restriction, smoothing) are applied to reduce disclination, then disclination is reduced, but image quality deteriorates (edges dull, brightness and contrast ratio decrease)
Solution Approach 1:
The patent applies different image processing methods dynamically based on the type of input image signal. The processor selectively applies level restriction, smoothing, or combinations thereof depending on whether the input is characterized by sharp edges (requiring level restriction) or high brightness/contrast (requiring smoothing), thereby adapting the disclination reduction approach to preserve appropriate image quality characteristics for each case
Solution Approach 2:
The patent applies different processing strategies to different regions or types of image content. By analyzing the input image signal characteristics and applying level restriction specifically for edge-containing content while using smoothing for high-contrast content, the system applies quality preservation locally according to the specific image characteristics rather than using a uniform approach
2Reliability
If level restriction processing is applied, then disclination is reduced, but edge sharpness deteriorates
Solution Approach 1:
The processor dynamically selects whether to apply level restriction based on the detected characteristics of the input image signal. When the signal is determined to contain character or figure content requiring sharp edges, level restriction is applied; otherwise, alternative processing is used, making the edge sharpness preservation dynamic rather than static
3Reliability
If smoothing processing is applied, then disclination is reduced, but brightness and contrast ratio deteriorate
Solution Approach 1:
The system dynamically determines whether smoothing processing should be applied based on the input image signal characteristics. When the signal is characterized by high brightness and contrast requirements, smoothing is selected; when sharpness is more critical, other methods are used, thereby dynamically preserving brightness and contrast ratio based on content needs

AI summary
A liquid crystal display apparatus, which displays an image on the basis of an input image signal input from an outside, includes a liquid crystal display element, a processor that performs a plurality of processing to reduce disclination in the liquid crystal element with respect to the input image signal selectively or in combination so as to acquire an output image signal, and a liquid crystal driver that drives the liquid crystal display element using the output image signal.
