Solution Overview

Problem

Existing display technologies face challenges in achieving optimal display effects for videos and images due to a fixed manner of HDR processing that does not match the characteristics of the to-be-displayed content, resulting in poor display quality.

Innovation Solution

A display drive method based on frame data that calculates the Average Picture Level (APL) percentage of the frame data and performs HDR processing accordingly, ensuring that the HDR processing manner aligns with the characteristics of the frame data to optimize the display effect.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a fixed manner of HDR processing is applied to video or image data, then the processing is simple and consistent, but the display effect is poor because it does not match the characteristics of the to-be-displayed content

Engineering Contradiction:
ImproveHDR processing simplicityVSAvoiddisplay effect quality
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent applies dynamics by making the HDR processing manner adaptive and changeable based on the APL percentage of the frame data. Instead of using a fixed processing method, the system dynamically selects different HDR processing parameters according to the calculated APL value, allowing the processing to match the characteristics of different video or image content while maintaining operational simplicity through automated adaptation.

Inventive Principle:
Principle #15Dynamics

2Productivity

If HDR processing is performed without considering frame data characteristics, then the processing speed is fast, but the display quality is poor

Engineering Contradiction:
ImproveHDR processing speedVSAvoiddisplay quality
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent applies preliminary action by calculating the APL percentage of the frame data before performing HDR processing. This pre-calculation step enables the system to determine the appropriate HDR processing manner in advance, so that when HDR processing is executed, it can be performed quickly with the correct parameters already selected, thus maintaining high processing speed while ensuring optimal display quality.

Inventive Principle:
Principle #10Preliminary action

3Manufacturing precision

If a customized HDR processing manner is implemented for different frame data characteristics, then the display effect is optimized, but the system complexity increases

Engineering Contradiction:
Improvedisplay effect optimizationVSAvoidHDR processing system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by using the APL percentage as a key parameter to determine the HDR processing manner. Instead of implementing a complex system that analyzes multiple aspects of frame data, the solution changes the processing parameters based on a single calculated parameter (APL percentage), which simplifies the system architecture while still enabling customized HDR processing for different content characteristics and achieving optimized display effects.

Inventive Principle:
Principle #35Parameter changes
