Flat Panel Display Scan Method for Response Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-resolution flat panel displays, the response time is significantly impacted by the conventional scan methods, which do not efficiently utilize the saved time from divided scanning, leading to suboptimal image processing and additional processing challenges.
Innovation Solution
A scan method that divides the display into K groups of lines, determines K sequences based on shift values, and synchronously scans these lines according to a specific order, optimizing the scan process by interlacing sequences to achieve efficient scanning of all lines within a single time frame, thereby enhancing processing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional scan methods are used in high-resolution displays, then the display can show high resolution, but the response time becomes slow
Solution Approach 1:
The patent divides the display lines into multiple groups (first group, second group, third group, etc.) and assigns different scan orders to each group. This segmentation allows simultaneous scanning of multiple line groups, effectively parallelizing the scanning process and reducing the overall response time while maintaining high resolution display capabilities
2Productivity
If lines are divided into multiple groups for scanning, then the scanning can be parallelized, but the scan order becomes complex
Solution Approach 1:
The patent employs periodic scan patterns for different line groups, where each group follows a regular scanning sequence (e.g., sequential scanning for the first group, reverse sequential for the second group, alternating patterns for subsequent groups). This periodicity simplifies the control logic compared to arbitrary complex patterns, as the same basic patterns are repeated across different line groups with predictable timing
Solution Approach 2:
The patent pre-defines specific scan orders for different line groups before actual scanning begins. These predetermined patterns (sequential, reverse sequential, alternating) are established in advance, allowing the scanning system to execute complex multi-group scanning without real-time decision complexity, as the scan paths are already determined
3Ease of operation
If conventional sequential scanning is used, then the control is simple, but the processing time is insufficient for additional processes
Solution Approach 1:
By segmenting lines into multiple groups with different scan orders, the patent creates parallel scanning channels that execute simultaneously. This segmentation multiplies the effective processing capacity within the same time frame, providing sufficient processing time for additional operations while keeping individual group control relatively simple
Solution Approach 2:
The patent merges multiple scanning operations into a single unified scanning process by coordinating different scan orders across line groups. Instead of performing separate scanning passes that would sequentially consume time, the merged parallel scanning approach combines multiple line group scans into one synchronized operation, effectively multiplying productivity

AI summary
A scan method for use in a flat panel display comprising K groups of lines, comprising the following steps. First, K sequences S1 to SK are provided. A scan order is then determined according to the K sequences S1 to SK. Thereafter, the K groups of lines are synchronously scanned by the scan order. K is an integer not less than 2. Each group of lines comprises at least M lines.
