Multi-Component Display Pre-Sharpening for Moire Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-component displays experience image blurriness and Moiré interference due to interstitial layers, which conventional diffusers attempt to mitigate by blurring images, leading to a tradeoff between reducing Moiré interference and maintaining image clarity.
Innovation Solution
A method of processing graphical data to preemptively compensate for distortion caused by interstitial layers and display screens by amplifying high-frequency components, using techniques such as low-pass filtering and transforming data between color spaces, to improve display quality by sharpening images before display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If diffusers are used to reduce Moiré interference, then Moiré interference is reduced, but image sharpness deteriorates due to blurring
Solution Approach 1:
The patent applies preliminary sharpening to the graphical data before display, anticipating and compensating for the blurring effect that will occur when light passes through the diffuser. This pre-processing action counteracts the subsequent degradation, allowing the use of diffusers for Moiré reduction without sacrificing perceived image sharpness
Solution Approach 2:
The patent implements preliminary anti-action by applying sharpening filters to graphical data in advance, creating an opposing effect that counteracts the blurring caused by the diffuser. This preemptive counter-measure ensures that the net effect maintains both Moiré reduction and image sharpness
2Object-affected harmful factors
If the distance between rear display screen and diffuser is increased, then Moiré interference is reduced, but image clarity deteriorates
Solution Approach 1:
The patent applies preliminary sharpening processing to graphical data to compensate for the image degradation caused by increasing the distance between the display screen and diffuser, allowing optimal Moiré reduction while maintaining perceived image clarity through digital pre-processing
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
The method enhances the optical characteristics of multi-component displays, reducing blurriness and Moiré interference while maintaining sharpness and color balance, thereby improving overall display quality without relying on image blurring.
Implementation Method 1
The pre-sharpening amplifies the high frequency components of the displayed graphical objects to compensate for the dampening caused by passing the graphical objects through the components of the multi-component display
Implementation Method 2
diffusers are commonly used in multi-component displays to reduce the effect of banding or other repeated patterns, commonly known as Moiré interference
Data Source
AI summary
A method, computer-usable medium, and system for processing graphical data for display on a multi-component display is disclosed. Embodiments improve the display quality of multi-component displays by modifying graphical data to preemptively compensate for distortion caused by interstitial layers and/or display screens of the multi-component display, thereby enabling display of graphical objects from multi-component displays with improved optical characteristics. For example, where components of a multi-component display blur displayed images, graphical data used to display graphical objects may be modified to sharpen the graphical objects before display. The pre-sharpening amplifies the high frequency components of the displayed graphical objects to compensate for the dampening caused by passing the graphical objects through the components of the multi-component display.
