Display Panel Driving Structure for Selective Driver Data Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels with multiple drivers face inefficiencies in data signal updating, requiring restarts from the first driver and consuming significant time, which reduces efficiency and increases power consumption.
Innovation Solution
A driving structure where a controller sets signal levels of data and data clock signals based on whether a driver needs to update data, and drivers transmit enable signals according to data signal levels, optimizing data update operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the data signal needs to be transmitted again, the controller will first transmit a low-level enable signal so that all drivers transmit the low-level enable signal, then transmit a high-level enable signal to the first driver, then receiving of the data signal will start from the first driver, then all drivers can receive the data signal in sequence, but this process consumes a lot of time and reduces the efficiency of updating the data signal
Solution Approach 1:
The patent segments the data update process by driver status. It divides drivers into two groups: drivers that need data update and drivers that do not need update. The controller selectively transmits enable signals only to drivers that need updating, rather than forcing all drivers to go through the complete sequential reception process. This segmentation allows parallel processing of updates for different driver groups, significantly reducing total update time while maintaining data integrity.
Solution Approach 2:
The patent implements preliminary action by having the controller determine which drivers need data updates before initiating the data transmission process. The controller pre-identifies the subset of drivers requiring updates and prepares the enable signal transmission accordingly. This preliminary identification eliminates the need for all drivers to undergo the complete sequential data reception process, thereby reducing overall update time while ensuring that only necessary drivers receive updated data.
2Productivity
If all drivers complete the operation of receiving data in sequence, then data can be updated across the display panel, but the process consumes significant power due to the large number of drivers operating simultaneously
Solution Approach 1:
The patent segments the driver population into active update groups and inactive groups. Only drivers that require data updates are activated with enable signals, while other drivers remain in a low-power state. This selective activation dramatically reduces the number of drivers consuming power during data update operations, directly addressing the power consumption issue while maintaining update efficiency for the necessary drivers.
Solution Approach 2:
The patent applies partial action by having only the necessary subset of drivers perform the data reception and update operation, rather than all drivers performing the complete operation. The controller transmits enable signals selectively to only those drivers that need updating, allowing partial execution of the data update process across the driver array. This reduces overall power consumption while achieving the required update productivity.
