Display Panel Shared Pixel Driving for Narrower Borders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with wide borders and non-display regions, particularly in miniaturized or special-shaped panels, face challenges in achieving a high screen-to-body ratio and user experience due to the presence of rounded corners and non-display areas that occupy significant space.
Innovation Solution
A display panel design with a first display region surrounding a second display region, where a single first driving circuit drives multiple first pixels simultaneously, reducing the number of driving circuits and utilizing the saved space for other components, thereby narrowing the border and increasing the display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single first driving circuit drives multiple first pixels simultaneously, then the number of driving circuits is reduced and border width is narrowed, but the complexity of driving circuit control increases
Solution Approach 1:
Multiple first pixels are merged into a single driving circuit control unit, allowing one driving circuit to simultaneously drive at least two first pixels. This merging reduces the total number of driving circuits required, thereby narrowing the border width and increasing the display area.
Solution Approach 2:
The first driving circuit is designed with multi-functionality to drive multiple first pixels simultaneously, making it a universal control unit that can manage multiple pixel elements. This increases the functional capability of each driving circuit while reducing the overall number of circuits needed.
2Area of stationary object
If the border width is narrowed to increase display area, then the screen-to-body ratio improves, but the difficulty of maintaining uniform brightness across different pixel densities increases
Solution Approach 1:
Different driving modes are applied to different regions: first pixels in the first display region are driven by first driving circuits while second pixels in the second display region are driven by second driving circuits. This localized differentiation allows optimization of brightness uniformity in each region while maintaining the overall narrow border design.
