Direct-Control Display Architecture for Low-Latency Image Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch-control display systems experience delays in updating images due to sequential processing through a touch screen, touch-control sensor, mainboard controller, CPU, graphics card, and display chip, affecting user experience.
Innovation Solution
A display system with a control component that sends direct control instructions to a display component, which includes a storage module for storing target display information, allowing direct communication and immediate display without relying on a graphics card for data output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If images are updated sequentially through touch screen, touch-control sensor, mainboard controller, CPU, graphics card and display chip, then the system can process touch control signals, but the image update delay increases to several frames
Solution Approach 1:
The patent extracts the graphics card from the signal processing chain and replaces it with a direct communication mechanism between the control component and display component. The control component directly sends control instructions to the display component, eliminating the sequential processing through CPU and graphics card, thus reducing image update delay while maintaining touch control functionality
Solution Approach 2:
The patent segments the display system into independent functional modules: a control component that handles touch control signals and generates control instructions, and a display component that stores display information and executes display operations. This segmentation allows each component to operate independently with direct communication, reducing the overall processing time for image updates
2Productivity
If a graphics card is used for data output, then the system can process images, but the communication path becomes complex and delay increases
Solution Approach 1:
The patent removes the graphics card from the communication path and establishes a direct connection between the control component and display component. This extraction simplifies the communication path while maintaining the ability to process and display images, as the control component directly generates and sends control instructions to the display component without requiring graphics card intervention
Solution Approach 2:
The control component is designed to perform multiple functions: receiving touch control signals, processing control instructions, and directly communicating with the display component. This multi-functionality eliminates the need for separate dedicated components for each function, simplifying the overall system architecture while maintaining image processing capability
