Single-Area Frame Memory Control for Display Data Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display devices require two memory areas for storing current and previous frame data, leading to increased memory capacity and power consumption.
Innovation Solution
A data processing device that performs reading of previous frame data and writing of current frame data in a single memory area using a writing line buffer and a reading line buffer, controlled by a memory controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two memory areas are used to store current and previous frame data, then the frame data correction function is achieved, but the memory capacity and size increase
Solution Approach 1:
The patent merges the function of storing current frame data and previous frame data into a single memory area. The memory controller manages both reading of previous frame data and writing of current frame data within the same memory space, eliminating the need for separate memory areas and thereby reducing memory capacity requirements.
Solution Approach 2:
The patent implements dynamic memory management where the memory area is flexibly allocated for different purposes at different times. The memory controller dynamically switches between reading previous frame data and writing current frame data within the same memory area, allowing the memory to serve multiple functions and reducing the total capacity needed.
2Reliability
If two memory areas are used to store current and previous frame data, then the frame data correction function is achieved, but the power consumption increases
Solution Approach 1:
The patent combines the storage function for both current and previous frame data into a single memory area, which reduces the total memory capacity required. Since power consumption in memory devices is directly proportional to capacity, this merging approach directly reduces power consumption while maintaining the frame data correction function.
3Reliability
If two memory areas are used to store current and previous frame data, then the frame data correction function is achieved, but the device size increases
Solution Approach 1:
The patent merges the storage functions into a single memory area, which directly reduces the physical size of the memory device. By eliminating the need for separate memory areas for current and previous frame data, the overall device footprint is reduced while maintaining full functionality.
