Display Driver Delay Circuit for Image Format Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display drivers with image data processing circuits face user-friendliness issues due to varying latency in image data processing operations, requiring users to adjust host settings based on image format, which complicates the timing of image data transmission.
Innovation Solution
Incorporating a delay circuit and an image data processing circuit that selects appropriate processing operations based on image format information, with the delay amount controlled to maintain consistent timing for image data transmission, allowing the host to supply data without format-specific adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an image data processing circuit is incorporated to perform multiple image data processing operations, then image processing capability and versatility are improved, but the timing of image data transmission must be adjusted according to image format, reducing ease of operation
Solution Approach 1:
The display driver automatically determines the appropriate image data processing operation based on the image format of the input data and configures the delay circuit accordingly. This self-service mechanism eliminates the need for users to manually adjust host settings based on image format, resolving the contradiction between versatile image processing capability and ease of operation
Solution Approach 2:
The delay circuit dynamically changes its delay period parameter based on the image format. When different image formats are detected, the delay circuit adjusts its delay period to compensate for variations in processing time, ensuring consistent timing for the display panel regardless of the processing operation being performed
2Device complexity
If the delay period is fixed, then device complexity is reduced, but timing consistency across different image formats cannot be maintained, reducing reliability
Solution Approach 1:
The delay circuit is designed with dynamic adjustability, allowing the delay period to be changed based on the image format. This dynamic characteristic enables the system to maintain timing consistency across different image formats (improving reliability) without requiring overly complex fixed-delay mechanisms for each possible format (controlling device complexity)

AI summary
A display driver for driving a display panel includes a delay circuit configured to receive first image data and output the received first image data with a delay; an image data processing circuit configured to select a selected image data processing operation from among a plurality of predefined image data processing operations in response to image format information specifying the format of the first image data, and generate second image data by performing the selected image data processing operation on the first image data received from the delay circuit; and a drive circuitry driving the display panel in response to the second image data. The amount of the delay is controlled in response to the image format information.
