Display Module Timing Controller Handshake Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display modules lack a specific setting for an overall drive architecture, leading to inability to meet customization demands for display controllers, as they support all display controllers equally.
Innovation Solution
Incorporating a timing controller with an identification unit and a determination unit in the display module, which receives control signals from the display controller, identifies handshake signals, and determines whether the transmitted handshake parameters match pre-stored parameters, allowing only compatible display controllers to perform normal display communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display module supports all display controllers without specific settings, then the compatibility and ease of operation are improved, but the customization demand cannot be met and the display controller cannot be uniquely configured
Solution Approach 1:
The timing controller performs preliminary actions by storing handshake parameters in advance and automatically performing handshake verification when a display controller is connected. This preliminary configuration enables the system to subsequently support specific customized display controllers without requiring manual setup, thus resolving the contradiction between universal compatibility and customized configuration.
2Ease of operation
If the display module implements handshake verification with pre-stored parameters, then the customization demand is met and specific display controllers can be configured, but the device complexity increases due to the identification and determination units
Solution Approach 1:
The patent merges the identification unit and determination unit into the existing timing controller, which is already a necessary component in the display module architecture. By integrating these new functions into an existing component rather than adding separate dedicated units, the increase in device complexity is minimized while still achieving the customization capability.
3Ease of operation
If the display module performs handshake verification, then the customization demand is met, but the communication time increases due to the additional verification steps
Solution Approach 1:
The handshake parameters are prepared and stored in advance in the timing controller before actual communication begins. This preliminary preparation allows the verification process to proceed quickly by simply comparing transmitted parameters against pre-stored values, minimizing the time penalty for customization verification.

AI summary
Disclosed is a display module comprising a timing controller which comprises an identification unit and a determination unit, wherein the identification unit is configured to receive and identify a control signal sent by the display controller and output a first feedback signal to the display controller when the control signal is identified as a handshake signal, the first feedback signal being used for triggering the display controller to send a handshake parameter; and the determination unit is connected to the display controller, and is configured to receive the handshake parameter sent by the display controller, determine whether the handshake parameter matches a handshake parameter pre-stored in the determination unit, if so, determine that handshake is successful, and output a second feedback signal to the display controller, the second feedback signal being used for triggering the display controller to send a video signal, and if not, determine that handshake fails.
