Display Panel Transition Pixel Layout for Under-Screen Cameras
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electronic devices with display screens cannot achieve a full-screen design due to the need for notches or holes to accommodate front cameras and infrared sensing elements, limiting the display area and light transmittance.
Innovation Solution
A display panel with a first display area of higher light transmittance than a second display area, featuring a transition area with sub-pixels and pixel circuits arranged to reduce occupied space, allowing for under-screen integration of photosensitive components like cameras while maintaining image display capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a notch or hole is formed in the display screen to accommodate front camera and infrared sensing elements, then photosensitive components can be integrated, but the display area is reduced and full-screen display is not achieved
Solution Approach 1:
The patent implements under-screen integration by nesting photosensitive components (front camera, infrared sensing elements) beneath the display screen. The display panel is divided into a first display area with higher light transmittance for photosensitive component integration and a second display area with lower light transmittance for normal display, allowing components to be embedded without compromising display functionality.
Solution Approach 2:
The patent applies local quality by creating distinct regions within the display panel with different light transmittance characteristics. The first display area has higher light transmittance to allow light passage to photosensitive components, while the second display area has lower light transmittance optimized for display performance, enabling different functional zones within the same panel.
2Ease of operation
If pixel circuits are arranged in a traditional matrix pattern corresponding to each sub-pixel, then each sub-pixel can be independently controlled, but the occupied space increases and reduces the effective display area
Solution Approach 1:
The patent merges multiple pixel circuits into a shared column structure. Specifically, pixel circuits for multiple sub-pixels (across different rows) are arranged in the same column, allowing them to share common connection lines and control pathways. This reduces the total area occupied by pixel circuits while maintaining independent control capability through selective signal routing.
Solution Approach 2:
The patent transitions from a traditional one-to-one matrix arrangement to a many-to-one columnar arrangement, effectively changing the spatial organization dimension. Instead of spreading pixel circuits across both row and column dimensions for each sub-pixel, multiple pixel circuits are stacked or arranged vertically within the same column, utilizing the vertical dimension more efficiently to reduce overall footprint.

AI summary
A display panel and a display device. The display panel includes a first display area, a second display area and a transition display area between the first display area and the second display area. A light transmittance of the first display area is greater than a light transmittance of the second display area. The display panel includes a plurality of columns of first sub-pixels disposed in the transition display area arranged in a first direction, and each column of sub-pixels includes a plurality of first sub-pixels arranged in a second direction which intersects the first direction. A plurality of first pixel circuits corresponding to at least one column of first sub-pixels are distributed on a same column.
