Multi-Driver Display Panel Using Shared Logic Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with multiple panel drivers experience increased power consumption due to each driving controller generating operating signals independently.
Innovation Solution
Implementing a master panel driver that generates a common logic signal for multiple slave panel drivers, allowing slave panel drivers to receive and operate based on this signal without generating their own, thereby reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each panel driver generates its own operating signals independently, then each driver can operate autonomously, but power consumption increases
Solution Approach 1:
The patent merges the common logic signal generation function from multiple slave panel drivers into a single master panel driver. The master driver generates a common logic signal that is shared by all slave drivers, eliminating redundant signal generation circuits in slave drivers and reducing overall power consumption while maintaining autonomous operation capability through the distributed driver architecture
Solution Approach 2:
The master panel driver performs a universal function by generating common logic signals that serve multiple slave panel drivers simultaneously. This multi-functional approach allows one driver to perform the role of multiple independent drivers for common operations, reducing the total number of signal generation circuits and lowering power consumption
2Area of stationary object
If multiple panel drivers are used to drive different display regions, then display coverage is improved, but device complexity increases
Solution Approach 1:
The patent segments the display panel into multiple display regions, each driven by a dedicated panel driver (master or slave). This segmentation allows large display areas to be covered by distributing the driving function across multiple independent driver units, making the system manageable and scalable
Solution Approach 2:
The patent combines the common logic signal generation function across multiple segmented driver units into a single master driver. This merging of the common control function reduces the overall device complexity by eliminating redundant circuits in slave drivers, while the segmented architecture maintains the ability to drive large display areas

AI summary
A display device may include a display panel including a first display region and a second display region, a master panel driver configured to generate a common logic signal and to drive the first display region based on the common logic signal and a first slave panel driver configured to drive the second display region based on the common logic signal that is received from the master panel driver. No common logic signal is generated by the first slave panel driver.
