Display Line Timing Control for Low-Latency Image Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control systems experience unnecessary delays in displaying image data on liquid crystal displays due to varying times required for image data preparation across different lines, leading to inefficient processing and potential offset of displayed images.
Innovation Solution
Implementing a control mechanism where the display processing for image data is triggered only after the generation processing for each line or unit has completed, allowing for synchronized and timely display without premature initiation, thus minimizing delay and ensuring accurate image representation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shared phase difference ΔT is defined for all lines to ensure image data is not read before writing, then data integrity is maintained, but display delay increases unnecessarily for lines that require less processing time
Solution Approach 1:
The patent segments the image data processing into individual line units, each with its own phase difference adjustment. Instead of applying a uniform phase difference across all lines, the system determines separate phase differences for each line based on its specific processing time requirements. This allows each line to be displayed at the optimal time without compromising data integrity.
Solution Approach 2:
The patent applies local quality by tailoring the phase difference to each specific line's processing characteristics. Each line receives a customized phase difference ΔT_n based on its individual processing time, rather than using a one-size-fits-all approach. This ensures that lines with shorter processing times do not suffer unnecessary delays while maintaining proper data timing for lines that require more processing time.
2Reliability
If the phase difference ΔT is defined to accommodate the maximum processing time of all lines, then all lines can be processed safely, but lines with shorter processing times experience unnecessary delays
Solution Approach 1:
The system processes and displays each line independently with its own timing parameters. By segmenting the display process into line-by-line operations with individual phase differences, the system can optimize each line's display timing based on its specific processing completion time, rather than being constrained by the maximum processing time of all lines.
Solution Approach 2:
The patent implements dynamic phase difference adjustment where the phase difference ΔT_n for each line is determined based on its actual processing time. This dynamic approach allows the system to adapt timing parameters in real-time based on processing completion, optimizing display efficiency for each line while maintaining safety for lines with longer processing times.
3Reliability
If image processing is performed for all lines before display, then complete image data is available, but display response time increases
Solution Approach 1:
The patent segments the image processing into line-by-line operations that can be handled independently. Each line is processed and displayed sequentially with its own phase difference adjustment, allowing the system to maintain data completeness for each line while reducing overall display response time compared to processing all lines before display.
Solution Approach 2:
The system performs preliminary processing for each line as it becomes available, rather than waiting for all lines to be processed. By applying preliminary action to each line individually with customized phase differences, the system can display lines sooner without compromising data completeness, thereby reducing display response time.

AI summary
A display control device includes an image data generating section and a control section. The image data generating section is configured to perform generation processing for generating image data in a predetermined processing sequence for each of a plurality of predetermined data units of the image data. The control section is configured to control a display unit to execute display processing based on the image data in the processing sequence for each of the predetermined data units. The control section is configured to control the display unit so that the longer a first time relating to the generation processing for one of the predetermined data units of the image data is, the longer a second time until the display processing starts for the one of the predetermined data units of the image data is.
