Display Panel Driving With Combined Statistics for Seamless Half-Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels using dual-chip timing controllers to drive left and right half-screens separately exhibit an obvious boundary due to lack of unity in image processing, leading to reduced image quality.
Innovation Solution
A display panel driving method that combines statistical information from both timing controllers to process display data for adjacent display portions, ensuring consistency by considering the influence of each other's display conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dual-chip timing controllers are used to drive left and right half screens separately, then the timing controller requirements are met and production requirements are satisfied, but an obvious boundary appears at the junction of half screens reducing image quality
Solution Approach 1:
The patent merges the statistical information processing of both timing controllers by having each controller obtain and combine statistical information from both the first and second display portions. This allows both half screens to be processed with unified statistical characteristics, eliminating the boundary effect while maintaining the dual-chip architecture for meeting production requirements.
2Reliability
If each timing controller processes display data independently with its own image algorithm, then the corresponding half screen displays correctly, but the pictures on two halves lack unity forming an entire picture
Solution Approach 1:
The patent implements feedback by having each timing controller obtain statistical information from both display portions and use this combined information to process its display data. This feedback mechanism ensures that both half screens are processed with consistent statistical characteristics, achieving picture unity while maintaining reliable display of each half screen.
3Manufacturing precision
If statistical information is combined from both display portions, then consistency between half screens is improved, but the complexity of timing controller processing increases
Solution Approach 1:
The patent applies universality by designing the timing controllers to perform multiple functions: they process their own display data while also obtaining and combining statistical information from both display portions. This multi-functional approach achieves picture consistency without requiring additional dedicated devices, thereby managing processing complexity within the existing dual-chip architecture.

AI summary
A driving method for a display method includes: processing a first display data of a first display portion according to a first combined statistical information to obtain a first target display data used to drive the first display portion to illuminate; and processing a second display data of a second display portion according to a second combined statistical information to obtain a second target display data used to drive the second display portion to illuminate. The first combined statistical information is obtained by combining a first statistical information corresponding to the first display data with a second statistical information corresponding to the second display portion, and the second combined statistical information is obtained by combining the first statistical information corresponding to the first display data with the second statistical information corresponding to the second display portion.
