Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices face challenges in improving display quality due to jaggy issues in images displayed using subpixel signals, which degrade the resolution and overall image clarity.
Innovation Solution
The display device incorporates a drive circuit that allocates gradation data across adjacent pixels, generating subpixel signals for first, second, and third subpixels based on the gradation data of adjacent pixels, optimizing the distribution of gradation data to reduce jaggy effects and enhance display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If subpixel signals are used to drive display pixels, then device complexity is reduced and ease of manufacture is improved, but jaggy artifacts appear and manufacturing precision deteriorates
Solution Approach 1:
The drive circuit performs preliminary allocation of gradation data from adjacent pixels to subpixels before generating drive signals. This preliminary action ensures that each subpixel receives appropriately adjusted gradation data that accounts for spatial relationships, preventing jaggy artifacts while maintaining the simplified subpixel drive architecture
Solution Approach 2:
The patent applies different gradation data allocation strategies to different subpixels based on their spatial positions and the gradation data of adjacent pixels. Each subpixel receives customized gradation data tailored to its local context, improving display quality without requiring complete redesign of the drive circuit
2Manufacturing precision
If gradation data is allocated across adjacent pixels, then manufacturing precision and display quality are improved, but device complexity increases
Solution Approach 1:
The drive circuit merges the functionality of multiple pixel drivers into a single integrated circuit that handles gradation data allocation across adjacent pixels. This merging approach improves display quality through coordinated control while avoiding the need for separate complex drive circuits for each pixel
Solution Approach 2:
The drive circuit performs multiple functions: it drives subpixels, allocates gradation data from adjacent pixels, and generates optimized drive signals. This multi-functionality reduces the need for separate dedicated circuits, improving display quality without proportionally increasing device complexity

AI summary
Each pair of pixels including two pixels adjacent to each other includes two first sub pixels, two second sub pixels, and two third sub pixels. One of the two first sub pixels and one of the two second sub pixels are included in one of the pair of pixels. The other of the two second sub pixels and one of the two third sub pixels are included in the other of the pair of pixels. The other of the two third sub pixels and the other of the two first sub pixels are disposed across and included in both of the pair of pixels. The drive circuit allocates the gradation data of one pixel to the gradation data of another pixel adjacent to the one pixel and drives the first, second, and third sub pixels included in the other pixel based on the gradation data of the other pixel.
