Display Panel Source Driver Dual Mode Resolution Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-end liquid crystal display devices require timing controllers that can process high-resolution display data, leading to excessively high costs due to the need for specialized equipment.
Innovation Solution
A driving device for display panels with multiple source drivers that operate in two modes: one for expanding low-resolution data to match high-resolution panels and another for processing high-resolution data, allowing compatibility with both low and high-resolution timing controllers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a timing controller that can process high-resolution display data is used, then the display resolution capability is improved, but the cost of the timing controller becomes excessively high
Solution Approach 1:
The source driver is designed with dual working modes: a first working mode for expanding low-resolution display data and a second working mode for processing high-resolution display data. This multi-functionality allows the same source driver to work with both low-resolution and high-resolution timing controllers, eliminating the need for specialized expensive timing controllers while maintaining high-resolution display capability.
2Adaptability or versatility
If the source driver expands low-resolution display data, then compatibility with low-resolution timing controllers is improved, but the display resolution is reduced
Solution Approach 1:
The source driver dynamically switches between two working modes based on the capabilities of the connected timing controller. When a low-resolution timing controller is detected, the source driver activates its data expansion function to increase display resolution. When a high-resolution timing controller is detected, the source driver switches to processing mode to maintain native high-resolution display. This dynamic adaptation resolves the contradiction between compatibility and display quality.

AI summary
A driving device of a display panel and a display device are provided. A source driver expands display data of a low-resolution image to be displayed in a first working mode, and cooperates with the source driver to receive and processes display data of a high-resolution display image in a second working mode, which makes the driving device of the display panel has good compatibility.
