Display Timing Controller Segmented Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices, such as LCD and OLED, face delays during the initial driving period due to the need to transmit large amounts of compensation reference data, which can lead to user inconvenience as they wait for complete data transmission before displaying images.
Innovation Solution
A display device and method that reconstructs compensation reference data into transmission data and sequentially transmits it to a second memory, allowing partial data transmission and storage, enabling image display before complete data is received, thereby reducing initial driving period delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compensation reference data is stored in nonvolatile memory, then data reliability is improved, but transmission time and display delay increase due to communication bandwidth limitations
Solution Approach 1:
The patent divides the large compensation reference data into multiple transmission data packets and transmits them sequentially to the second memory (RAM) in stages. This segmentation allows the system to start displaying images using partially received data before all data transmission is complete, thereby reducing display delay while maintaining data reliability through structured transmission and storage.
2Loss of time
If compensation reference data is stored in volatile memory, then transmission time is reduced, but data reliability deteriorates due to write limitations and power loss risks
Solution Approach 1:
The patent introduces a second memory (RAM) as an intermediary between the nonvolatile memory (first memory) and the display processing system. Compensation reference data is transmitted from the first memory to the second memory in segmented packets, allowing fast access and processing while maintaining data integrity through controlled transmission protocols. This intermediary structure enables both fast transmission and reliable data handling.
3Manufacturing precision
If complete compensation reference data is transmitted before displaying images, then image quality is improved, but user convenience deteriorates due to initial display delay
Solution Approach 1:
The patent performs preliminary transmission and storage of compensation reference data in segmented packets to the second memory before complete image display is required. The system starts displaying images using the partially received compensation data, providing immediate visual feedback to users. The remaining data transmission continues in the background, ensuring complete image quality enhancement without forcing users to wait for full data reception.

AI summary
Systems and methods are described for displaying an image during an initial driving period. An exemplary display device includes a timing controller configured to reconstruct compensation reference data from a first memory into a plurality of transmission data, sequentially transmit the plurality of transmission data to a second memory, and display an image on the display panel when partial transmission data of the plurality of transmission data are transmitted and stored to the second memory during the initial driving period.
