Display Panel Driver Layout for Under-Screen Camera Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of photosensitive elements, such as cameras, under a display screen in electronic devices leads to poor display uniformity due to space constraints and inefficient driving unit placement.
Innovation Solution
A display panel design with distinct regions, where photosensitive elements are placed in one region and driving units are strategically positioned outside this region to maintain uniformity, ensuring one-to-one correspondence and optimal space utilization, with driving unit projections adjusted to prevent excessive inclination and occupation of space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If photosensitive elements are integrated under the display screen to achieve full screen design, then screen-to-body ratio is improved, but display uniformity deteriorates
Solution Approach 1:
The display panel is divided into distinct first display region and second display region along the first direction. The first display region contains normal sub-pixels and driving units, while the second display region is specifically designed to accommodate photosensitive elements. This spatial segmentation allows the photosensitive elements to be integrated under the screen without compromising the display uniformity of the primary display area, thus resolving the contradiction between achieving full screen design and maintaining display quality.
2Area of stationary object
If driving units are arranged in the second display region with photosensitive elements, then space utilization is improved, but driving unit size uniformity deteriorates due to area constraints
Solution Approach 1:
Different driving unit area specifications are applied to different regions: driving units in the first display region have a first area S1, while driving units in the second display region have a second area S2, where S1:S2≥1. This local differentiation allows driving units in the photosensitive element region to be optimized for smaller size to accommodate space constraints, while maintaining standard size in the primary display region, thus achieving both space utilization and regional functional requirements.
Solution Approach 2:
The patent introduces a new spatial dimension by creating a distinct second display region along the first direction, separate from the traditional first display region. This dimensional separation allows driving units in the second region to have different area characteristics (S2) compared to the first region (S1), enabling optimized space utilization in the photosensitive element region without compromising the driving unit uniformity in the main display area.
3Manufacturing precision
If separate driving units are provided for each region, then pixel driving precision is improved, but device complexity increases
Solution Approach 1:
While separate driving units are provided for the first and second display regions to ensure precise pixel driving in each area, the patent establishes systematic relationships between them through the defined area ratio S1:S2≥1 and spatial arrangement along the first direction. This universal design framework allows the complex multi-region driving system to be managed through standardized proportional relationships, reducing the overall complexity compared to completely independent driving systems for each region.
