Image Processor Circuit Reduces Display Panel Start-Up Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing TV systems, the delay in starting to display images due to low-speed data transmission between the image processing chip and the display device results in a poor user experience, as the chip needs to read complete information after every boot procedure.
Innovation Solution
An image display system comprising a display device, a first memory circuit for storing predetermined data, and a second memory circuit with a faster data transfer rate, where the image processor circuit reads and compares partial data from both memory circuits to output a driving signal only when the data is identical, thereby reducing the time to start displaying images.

Engineering Contradiction Analysis
1Reliability
If the image processing chip reads complete information from the display device through a low-speed transmission interface after every boot procedure, then the panel can display images with accurate control parameters, but the time for the panel to start displaying images is delayed
Solution Approach 1:
The patent applies preliminary action by pre-storing panel information in the image processing chip during manufacturing. This allows the chip to have panel control parameters ready before the actual display operation begins, eliminating the need to read all information from the display device during boot-up. The pre-stored information enables immediate panel control while maintaining accuracy.
Solution Approach 2:
The patent segments the panel information into two parts: critical control parameters that are pre-stored in the image processing chip, and other non-critical information that can be read later or omitted. This segmentation allows the system to use only the essential pre-stored data for immediate panel operation, significantly reducing start-up time while maintaining display control accuracy.
2Measurement precision
If the image processing chip reads complete information from the display device through a low-speed transmission interface, then the panel can be controlled based on accurate information, but the data transmission time increases
Solution Approach 1:
The patent applies preliminary action by pre-storing panel information in the image processing chip during manufacturing. This allows the chip to have panel control parameters ready before the actual display operation begins, eliminating the need to read all information from the display device during boot-up. The pre-stored information enables immediate panel control while maintaining accuracy.
Solution Approach 2:
The patent applies partial action by reading only necessary panel information from the display device rather than complete information. The image processing chip uses pre-stored data for immediate operation and only selectively reads additional information when needed, reducing data transmission time while maintaining sufficient accuracy for proper panel control.

AI summary
An image display system includes a display device, a second memory circuit, and an image processor circuit. The display device includes a panel and a first memory circuit, in which the first memory circuit is configured to store first predetermined data for controlling the panel. The second memory circuit is configured to store second predetermined data. The image processor circuit is configured to read first part data in the first predetermined data and second part data in the second predetermined data and compare the first part data with the second part data. If the first part data is identical to the second part data, the image processor circuit is further configured to output a driving signal according to the second predetermined data to control the panel to start displaying an image.
