Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As display panel sizes increase, the computational demands for controlling them also rise, leading to performance challenges in distributing processing within display apparatuses, which existing technologies have not adequately addressed.
Innovation Solution
The implementation of a multi-timing controller system where first, second, and third timing controllers are synchronized using a reference clock signal and a state synchronization signal to control different regions of the display panel, allowing for efficient operation and data exchange through internal reference and synchronization clock signals, and operating in various states based on the display apparatus's operation.

1Area of stationary object
If display panel size is increased, then display area is improved, but computational demand increases causing performance degradation
Solution Approach 1:
The patent divides the display panel into multiple regions, each controlled by a separate timing controller. This segmentation distributes the computational load across multiple controllers, preventing any single controller from becoming a bottleneck. Each timing controller manages a specific region's pixel data and control signals, thereby maintaining processing performance while supporting larger display areas.
Solution Approach 2:
The patent introduces a multi-dimensional control architecture by adding spatial distribution of timing controllers across different display regions. Instead of a single centralized controller, the system uses multiple controllers arranged in a distributed manner, adding a spatial dimension to the control architecture that enables scalable performance for larger displays.
2Productivity
If multiple timing controllers are distributed across different regions, then processing performance is improved, but synchronization complexity increases
Solution Approach 1:
The patent merges the clock signal generation function into a single reference clock source that is shared by all timing controllers. This consolidation ensures that all controllers operate on a unified time base, simplifying synchronization. The reference clock signal is distributed to each timing controller, which then generates its own output clock signals based on this common reference, reducing synchronization complexity while maintaining distributed processing performance.
Solution Approach 2:
The patent implements a feedback mechanism where timing controllers monitor and adjust their operations based on the reference clock signal and regional display requirements. This feedback loop ensures that each controller remains synchronized with the overall system while independently managing its region's computational tasks, balancing performance distribution with synchronization simplicity.
3Reliability
If a single reference clock signal is shared across all timing controllers, then synchronization is improved, but signal distribution complexity increases
Solution Approach 1:
The patent segments the clock signal distribution into hierarchical levels: a master reference clock signal is generated by one timing controller and distributed to other controllers, which then generate their own regional clock signals. This segmentation of the clock distribution architecture reduces the complexity of signal routing while maintaining synchronization reliability across all display regions.
Data Source
AI summary
A display apparatus includes a display panel, a first timing controller, a second timing controller and a third timing controller. The first timing controller controls an operation of a first region in the display panel, and generates a reference clock signal. The second timing controller controls an operation of a second region in the display panel, and receives the reference clock signal. The third timing controller controls an operation of a third region in the display panel, and receives the reference clock signal. The first, second and third timing controllers are synchronized with one another in response to the reference clock signal and a state synchronization signal, and operate in one of a plurality of states depending on an operation of the display apparatus.
