Supplementary Gate Scanning for Higher-Resolution Display Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face challenges in efficiently processing high-definition and high-refresh-rate display signals, leading to increased costs and reduced popularity of ultra-high resolution and refresh rate panels due to the significant increase in data requirements, which strains the processing capabilities of system chips and transmission paths.
Innovation Solution
A signal processing method that generates supplementary gate scan signals to expand the vertical resolution of display panels by interspersing additional gate scan signals between existing ones, ensuring all pixel units are driven, and a data supplement operation to handle column data mismatches, using a timing controller and source driver chip to manage these signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the display panel uses ultra-high resolution and refresh rate, then the display quality is improved, but the data requirements significantly increase, straining processing capabilities and transmission paths
Solution Approach 1:
The gate scan signals are segmented into original signals and supplementary signals. The supplementary gate scan signals divide the scanning process into finer time intervals, allowing the display panel to process and display high-definition images with improved quality without requiring a proportional increase in overall data transmission volume, thus resolving the contradiction between display quality and data requirements
Solution Approach 2:
The supplementary gate scan signals are generated in advance based on the original gate scan signals before the actual display process. This preliminary generation of additional scanning signals prepares the system to handle high-definition content efficiently, enabling the display panel to process complex high-quality images without straining the transmission paths during real-time operation
2Measurement precision
If the display panel increases vertical resolution, then the display capability is improved, but the number of gate scan signals required increases, increasing device complexity
Solution Approach 1:
The supplementary gate scan signals act as an intermediary mechanism between the original gate scan signals and the pixel units. These intermediate signals enable the display panel to achieve higher vertical resolution by introducing additional scanning steps without directly increasing the complexity of the primary signal generation system, thus resolving the contradiction between vertical resolution and device complexity
3Measurement precision
If the display panel processes high-definition images, then the display effect is improved, but the processing capabilities of system chips are strained
Solution Approach 1:
The display system dynamically adjusts by introducing supplementary gate scan signals that adapt to the display requirements. This dynamic signal generation allows the system to process high-definition images with improved display effect while distributing the processing load over time through additional scanning cycles, thereby reducing the instantaneous processing burden on system chips and resolving the contradiction between display effect and processing capabilities
