Display Panel Data Transfer Module for High-Resolution Image Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-resolution display panels require significant computing resources and increased power consumption due to the need for large registers and caches to buffer pixel data, leading to delays in data output and higher fabrication costs.
Innovation Solution
A data transfer method that uses a reduced number of registers and caches by sequentially collecting and processing pixel data in primary and secondary caches, applying a color mixing process to generate display data, and transferring it to the display panel, thereby reducing the computational load and delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If large registers and caches are used to buffer pixel data for high-resolution display, then the display resolution is improved, but the power consumption and device complexity increase
Solution Approach 1:
The patent divides the buffering process into two separate caches: a first cache for buffering pixel data and a second cache for buffering processing results. This segmentation allows each cache to be smaller in capacity, reducing overall power consumption while maintaining high-resolution display capability. The pixel data cache stores only raw input data, while the result cache stores processed output, eliminating the need for one large universal buffer.
Solution Approach 2:
The patent extracts the color mixing process from the general pixel processing pipeline, implementing it as a separate, dedicated function in the data processing unit. This extraction allows the system to process only the necessary color component data rather than buffering and processing all pixel data components, thereby reducing the buffering requirements and associated power consumption.
2Measurement precision
If large registers and caches are used to buffer pixel data for high-resolution display, then the display resolution is improved, but the device complexity and fabrication cost increase
Solution Approach 1:
The patent segments the data processing function into distinct modules: a data processing unit for color mixing, a first cache for pixel data, and a second cache for processing results. This modular segmentation simplifies the overall device architecture by assigning specific functions to specific components, making the driving IC less complex while supporting high-resolution display.
Solution Approach 2:
The patent extracts the color mixing operation as a separate, dedicated processing function within the data processing unit, rather than requiring general-purpose processing resources. This extraction reduces the computational complexity of the driving IC by implementing only the necessary color mixing logic without needing more complex general-purpose processors.
3Use of energy by stationary object
If sequential data collection and processing is used with reduced caches, then the power consumption is reduced, but the data processing speed may be affected
Solution Approach 1:
The patent implements continuous data flow between the first cache, data processing unit, and second cache. Pixel data is continuously collected in the first cache, processed in real-time through the color mixing unit, and output to the second cache without interruption. This continuous processing maintains high data processing speed despite the reduced cache capacity and sequential operation mode.
Solution Approach 2:
The patent introduces the second cache as an intermediary buffer between the processing unit and the display output. This intermediary allows the processing unit to operate sequentially at lower power consumption while maintaining the overall system throughput, as the second cache decouples the processing speed from the display refresh rate.

AI summary
The present disclosure provides a method for transferring data for displaying images at a first resolution to a display panel of a second resolution, the first resolution being higher than the second resolution. The method includes steps of sequentially collecting and storing pixel data into primary caches; sequentially transferring the pixel data stored in the primary caches to a data processing unit; and applying a color mixing process to received pixel data according to a time-sharing operation to generate display data. The method also includes sequentially transferring the display data to secondary caches and repeating the steps until pixel data for a row of pixel structures corresponding to the first resolution are processed and stored in the secondary caches as display data, and transferring the display data to a row of pixel structures corresponding to the second resolution.
