Dual-Media Display Panel Driving Signal Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for driving dual-media display panels require separate timing controllers for transparent and light-shielding panels, increasing manufacturing costs due to the inability to efficiently display black color with transparent panels.
Innovation Solution
A method where a processor generates driving signals for both panels based on display data, using grayscale values to determine when to display black or white on the light-shielding panel, eliminating the need for dedicated timing controllers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate timing controllers are used for transparent and light-shielding display panels, then each panel can be driven independently, but manufacturing costs increase
Solution Approach 1:
The patent merges the functions of two separate timing controllers into a single timing controller that can drive both the transparent display panel and the light-shielding display panel. This is achieved by integrating multiple driving signal generation circuits within one timing controller, reducing the total number of controllers while maintaining independent driving capability for each panel type.
Solution Approach 2:
The timing controller is designed with multi-functionality to handle different display panel types. It includes a transparent display panel driving signal generation circuit and a light-shielding display panel driving signal generation circuit, allowing a single controller to perform multiple functions that previously required separate dedicated controllers.
2Ease of manufacture
If transparent display panel is used alone, then manufacturing cost is reduced, but black color cannot be displayed
Solution Approach 1:
The patent combines the transparent display panel and the light-shielding display panel into a dual-media display system. The transparent panel provides visibility and color display, while the light-shielding panel compensates for the inability to display black, achieving a balance between manufacturing simplicity and display capability.
3Adaptability or versatility
If dual-media display panel is used, then black color can be displayed, but power consumption increases
Solution Approach 1:
The patent implements dynamic control of the light-shielding display panel based on the grayscale values of the display content. The controller adjusts the driving signals to the light-shielding panel dynamically, activating it only when black or dark colors need to be displayed, thereby reducing unnecessary power consumption while maintaining the ability to display black when required.
Data Source
AI summary
A method for driving a dual-media display panel includes the following. Display data is obtained. A first driving signal for driving a transparent display panel of the dual-media display panel is generated in response to the display data. A display-unit grayscale value for the display data is obtained. The display-unit grayscale value is determined whether it falls within a grayscale value interval. When the display-unit grayscale value is less than a lower limit of the grayscale value interval, a driving signal adapted to enabling the light-shielding display panel to display a black color is used as the second driving signal. When the display-unit grayscale value is greater than an upper limit of the grayscale value interval, a driving signal adapted to enabling the light-shielding display panel to display a white color is used as the second driving signal.
