Display Controller Merging Pixel Frames for 3D Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D display systems require additional components and processing due to the need for separate presentation of left and right images, increasing cost and complexity.
Innovation Solution
A display controller comprising a merger and an alpha blender that mixes and blends pixel data frames according to a 3D display format, eliminating the need for extra hardware by generating a stereoscopic perception of 3D depth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate left and right image processing is used for 3D display, then stereoscopic perception is achieved, but device complexity and cost increase
Solution Approach 1:
The patent combines the functions of separate left and right image processing into a single display controller unit. The controller integrates multiple processing stages (separation, formatting, and recombination) that were previously handled by distinct components, thereby reducing device complexity while maintaining stereoscopic perception capability.
Solution Approach 2:
The display controller is designed to perform multiple functions: it separates interlaced pixel data into left and right images, formats them according to different 3D display formats (side-by-side, top-bottom, interlaced), and recombines them for display. This multi-functional approach eliminates the need for dedicated hardware for each processing stage.
2Productivity
If additional components are used for 3D image processing, then processing capability is improved, but manufacturing cost increases
Solution Approach 1:
The patent merges multiple processing functions (image separation, format conversion, and recombination) into a single integrated display controller, eliminating the need for separate chips or components for each function. This integration reduces manufacturing cost while preserving full processing capability for various 3D display formats.
Solution Approach 2:
The display controller is designed as a universal processing unit that can handle multiple 3D display formats (side-by-side, top-bottom, interlaced) through software-based format selection rather than requiring dedicated hardware for each format. This approach maintains versatile processing capability while significantly reducing component count and manufacturing complexity.

AI summary
A display controller includes a merger and an alpha blender. The merger is configured to mix a first left frame including first left pixel data and a first right frame including first right pixel data based on a three-dimensional (3D) display format, and further configured and to output a first mixed frame and a second mixed frame. The alpha blender is configured to blend the first mixed frame and the second mixed frame to produce a first blended frame.
