Display Control Circuit Boot Speed via Parameter Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of functions for improving picture display quality in display devices leads to longer initialization times, resulting in slow boot speeds as the image processing chip reads configuration parameters from memory, delaying the display of boot animations.
Innovation Solution
A control method and circuit that separates the reading of configuration parameters into two phases: initial configuration parameters for basic image processing and image optimization parameters for subsequent processing, allowing for parallel execution of image basic and optimization processing to accelerate boot display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If all configuration parameters (basic and optimization) are read before displaying boot animation, then image processing quality is improved, but boot display speed deteriorates
Solution Approach 1:
The patent segments configuration parameters into two categories: basic configuration parameters (for data receiving, sending, and swapping) and image optimization configuration parameters (for gamma, overdrive, demura, color enhancement, and dithering). This segmentation allows the system to read and process parameters in stages, enabling boot animation display with basic functionality first, then applying optimization parameters subsequently, thus resolving the contradiction between complete initialization and fast boot display.
Solution Approach 2:
The patent applies preliminary action by reading and initializing basic configuration parameters before displaying the boot animation. This allows the system to perform essential setup (data receiving, sending, and swapping configurations) in advance, enabling the boot animation to be displayed immediately with basic functionality, while image optimization parameters are read and applied during or after the boot process, thus achieving fast boot display without completely sacrificing image quality.
2Manufacturing precision
If multiple image optimization functions are added to improve picture quality, then display quality is improved, but initialization time increases
Solution Approach 1:
The patent segments image optimization functions into distinct configurable modules (digital gamma, overdrive, demura, color enhancement, dithering), each with its own configuration parameters. This segmentation allows the system to initialize basic display functionality first, then progressively enable optimization functions based on configuration parameters read during boot, reducing overall initialization time while maintaining the capability for high-quality display.
Solution Approach 2:
The patent applies partial action by enabling image optimization functions selectively based on configuration parameters. Not all optimization functions need to be fully initialized and applied during boot - the system can enable basic display first, then progressively apply optimization functions as configuration parameters are read and processed, reducing initialization time while still providing enhanced display quality where configured.
