Solution Overview
Problem
In high-resolution and large-area display panels, multiple integrated circuits sharing data lines face challenges in efficient data transmission, particularly when sensing data needs to be re-transmitted, leading to potential collisions and inefficiencies.
Innovation Solution
The implementation of an integrated circuit design that includes a sensing circuit, a signal controlling circuit for 1:1 indication signal transmission, and a transmitting circuit for 1:N data transmission, allowing efficient data exchange between integrated circuits through dedicated signal and data lines, enabling regular or irregular re-transmission of data without collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple integrated circuits share a data line for transmitting sensing data, then device complexity is reduced, but data transmission reliability deteriorates due to potential collisions
Solution Approach 1:
The patent segments the data transmission system into two separate channels: a data line for transmitting sensing data and a control line for transmitting control signals. This segmentation allows independent optimization of each line's function, preventing collisions between data and control signals while maintaining the shared infrastructure benefit.
Solution Approach 2:
The patent introduces a control signal as an intermediary mechanism to manage access to the shared data line. The control signal acts as a mediator that coordinates transmission timing between multiple integrated circuits, ensuring that only one circuit transmits sensing data at a time while allowing efficient re-transmission when needed.
2Productivity
If a cascade carry method is used for data transmission, then data transmission is enabled in shared lines, but re-transmission efficiency deteriorates when data needs to be sent again
Solution Approach 1:
The patent implements a dynamic transmission control mechanism where the control signal can be actively adjusted based on transmission needs. When re-transmission is required, the control signal can be modified to allow immediate re-transmission without waiting for the entire cascade sequence to complete, thereby reducing time loss while maintaining the shared line benefit.
Solution Approach 2:
The patent incorporates feedback mechanisms where the control signal responds to transmission status information. When sensing data needs to be re-transmitted, the feedback loop detects this condition and adjusts the control signal accordingly, enabling efficient re-transmission without requiring the entire cascade carry sequence to restart, thus reducing time loss.
3Area of stationary object
If the number of integrated circuits increases for high-resolution panels, then panel coverage is improved, but data transmission collision probability increases
Solution Approach 1:
The patent segments the transmission medium into dedicated data lines and control lines, allowing multiple integrated circuits to operate simultaneously without collision on the data line. This segmentation enables increased panel coverage through more circuits while maintaining low collision probability by isolating data transmission paths.
Solution Approach 2:
The patent implements preliminary action through the control signal that is transmitted before sensing data. This preliminary control signal establishes transmission rights and timing in advance, allowing multiple integrated circuits to be assigned transmission slots beforehand, thereby preventing collisions even as the number of circuits increases for broader panel coverage.
