Timing Controller Register Transmission for Source Driver Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current register value transmission methods in display manufacturing, such as the P2P interface between a timing controller and a source driver, face inefficiencies due to fixed register value transmissions, leading to ignored values, unnecessary compensation, and reduced flexibility in matching register values between the sending and receiving ends, resulting in waste and increased power consumption.
Innovation Solution
A method where a timing controller generates an information setting instruction with a variable number of register values based on a triggered directive, encoded using 8b/10b encoding, and sent to the source driver, allowing flexible configuration setting without ignoring or compensating for register values, thereby simplifying the transmission process and enhancing matching flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed number of register values are transmitted each time, then the transmission process is simple, but the flexibility in matching register values between sending and receiving ends is reduced
Solution Approach 1:
The patent implements dynamic register value transmission where the timing controller can send a variable number of register values (n values) based on actual configuration needs rather than a fixed number. This allows the transmission system to adapt dynamically to different configuration requirements, resolving the contradiction between flexibility and complexity by making the system adaptable only when needed.
Solution Approach 2:
The patent changes the parameter of register value count from fixed to variable. By allowing the number of register values transmitted to be dynamically adjusted according to actual configuration needs, the system achieves better adaptability while maintaining manageable complexity through controlled parameter variation.
2Loss of substance
If a fixed number of register values are transmitted, then the transmission protocol is simple, but waste occurs when register values are ignored or compensated
Solution Approach 1:
The patent extracts only the necessary register values for configuration from the total possible register values. By sending exactly n values that are needed for specific configuration tasks rather than always transmitting a fixed set, the system eliminates waste of register values while keeping the protocol relatively simple through selective extraction.
Solution Approach 2:
The patent applies partial action by transmitting only the required number of register values (n values) rather than always transmitting a complete fixed set. This partial transmission approach avoids the waste of sending unnecessary register values while maintaining protocol simplicity through controlled, task-specific transmission.
3Use of energy by moving object
If fixed register value transmission is used, then power consumption is higher due to unnecessary transmissions, but the transmission method is simpler
Solution Approach 1:
The patent implements periodic or event-driven register value transmission triggered by configuration needs rather than continuous or fixed periodic transmission. This allows the system to transmit register values only when configuration changes are required, reducing unnecessary power consumption while maintaining a relatively simple transmission method through event-based activation.
Solution Approach 2:
The patent applies partial action by transmitting register values only when and only to the extent needed for configuration. This selective transmission approach reduces power consumption by avoiding unnecessary transmissions while keeping the transmission method simple through conditional, task-specific execution.

AI summary
Disclosed are a register value transmission method and transmitter, and a display device. The method may be used for a timing controller, and the method includes receiving a user triggered information setting directive including n register values for instructing a source driver to set configuration information of the source driver according to the n register values, n being greater than 1, generating an information setting instruction including the n register values according to the information setting directive, and sending the information setting instruction to the source driver. The disclosure solves the problem of low flexibility of matching the number of register values at both a receiving end and a sending end, and improves the flexibility of matching the number of register values.
