Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electronic devices with front cameras and sensors require notches or holes in the display screen, limiting the screen-to-body ratio and preventing full-screen display.
Innovation Solution
A display panel design with a high light transmittance area for integrating photosensitive components, featuring a transition area with shared pixel circuits and signal lines to minimize space occupation, allowing for full-screen display and under-screen integration of cameras.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a notch or hole is formed in the display screen to allow light to reach photosensitive elements, then the photosensitive component can be integrated, but the screen-to-body ratio is reduced and full-screen display is prevented
Solution Approach 1:
The patent moves the photosensitive component from the front display surface to the back surface of the display panel, utilizing the z-dimension (depth) rather than compromising the x-y plane (display area). This dimensional transition allows light to pass through the display panel from the front while the photosensitive element is positioned on the rear side, eliminating the need for notches or holes in the display screen.
2Ease of operation
If pixel circuits are distributed in a traditional matrix arrangement, then each pixel can be controlled independently, but the occupied area in the transition display region is large
Solution Approach 1:
The patent merges multiple pixel circuits into a shared column structure, where pixel circuits for multiple sub-pixels are arranged in the same column rather than occupying separate matrix positions. This merging approach maintains the independent control capability of each pixel while significantly reducing the total area occupied by pixel circuits in the transition display region.
Solution Approach 2:
The patent changes the spatial arrangement of pixel circuits from a two-dimensional matrix distribution to a one-dimensional columnar distribution. By concentrating pixel circuits along the first direction (forming columns) rather than spreading them across both directions, the patent reduces the area occupied in the transition display region while preserving the ability to independently control each pixel through the columnar organization.

AI summary
The application discloses 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, wherein 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. According to the display panel provided by embodiments of the application, an area occupied by first pixel circuits corresponding to a column of first sub-pixels can be reduced, and thus an occupied space in the transition display area can be reduced.
