Alternating Driving Transistors for Display Brightness Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies face issues with uneven brightness in display areas due to varying light transmittance, which affects the display effect and can be exacerbated by the presence of components like cameras and sensing units.
Innovation Solution
A display panel design featuring a first display area with higher light transmittance surrounded by a second display area, where driving transistors for both areas are alternately arranged to create a consistent parasitic capacitance environment, reducing brightness differences and improving display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If components such as camera, earpiece, and sensing unit are installed under the display area, then the display apparatus can provide integrated functionality, but uneven brightness may appear in the display area reducing display effect
Solution Approach 1:
The patent applies local quality by creating distinct display areas with different light transmittance characteristics. The first display area has higher light transmittance to accommodate photosensitive devices, while the second and third display areas have lower light transmittance for normal display content. This localized differentiation allows the camera and other components to function properly under the display without compromising overall display quality.
Solution Approach 2:
The display area is segmented into multiple regions: a first display area with higher light transmittance for photosensitive device operation, and second/third display areas with lower light transmittance for standard display content. This segmentation allows different functional requirements to be met simultaneously within the same display structure.
