Display Apparatus With Segmented Gate Drivers And Through Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses face challenges in efficiently managing multiple scanning periods and data signal transmission across different display areas, leading to increased power consumption and complexity in designing multi-functional displays with features like through holes for sensors or cameras.
Innovation Solution
The display apparatus incorporates a substrate with distinct display areas and non-display areas, utilizing multiple gate drivers and data lines to manage different scanning periods and data signal transmission, with a through hole allowing for the integration of additional features like sensors or cameras while optimizing the layout for reduced power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single gate driver is used for the entire display area, then the device complexity is reduced, but the power consumption increases and the ability to accommodate through holes is limited
Solution Approach 1:
The display area is divided into multiple independent display areas (first display area, second display area, third display area) with separate gate drivers (first gate driver, second gate driver, third gate driver) controlling each region. This segmentation allows different scanning periods to be applied to different areas, reducing overall power consumption while maintaining the ability to accommodate through holes in non-display regions.
2Adaptability or versatility
If through holes are added to accommodate sensors or cameras, then the functionality and versatility are improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
Through holes are created in the substrate to extract or remove material, allowing sensors, cameras, or other functional elements to be integrated into the display apparatus. The substrate is designed with these through holes in non-display areas, enabling additional functionality without significantly complicating the overall device structure.
3Use of energy by moving object
If different scanning periods are applied to different display areas, then the power consumption is reduced, but the device complexity increases
Solution Approach 1:
The display is segmented into multiple independent display areas, each controlled by its own gate driver with configurable scanning periods. This allows power-optimized operation where different regions can use different refresh rates based on their content requirements, reducing overall power consumption while maintaining manageable device complexity through modular architecture.

AI summary
A display apparatus includes first and second display areas, first pixels in the first display area, and second pixels in the second display area. Gate lines are connected to the first pixels. First gate electrode lines are connected to the second pixels. First gate driving lines are respectively connected to the first gate electrode lines. A first gate driver outputs first scanning signals to the first pixels via the gate lines. A second gate driver outputs second scanning signals to the second pixels via the first gate driving lines and the first gate electrode lines.
