Display Panel Fixed Potential Line Density for Light Transmittance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Full-screen display technologies face challenges in achieving uniform display brightness between transparent and conventional display regions due to issues like reduced anode area, signal line width, and storage capacitor size, leading to non-uniform display and reduced light transmittance.
Innovation Solution
The display panel design includes a conventional display region and a function display region with specific arrangements of pixel circuits and fixed potential lines, where the number of pixel circuit groups between adjacent fixed potential lines is adjusted to increase light transmittance while maintaining display uniformity, by reducing the density of second fixed potential lines in the function display region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the shading area of the transparent display region is decreased to improve light transmittance, then light transmittance is improved, but non-uniform display occurs
Solution Approach 1:
The patent applies different fixed potential line densities to different display regions. The function display region (with optical device) has a lower density of second fixed potential lines compared to the conventional display region, allowing higher light transmittance where the optical device is located, while the conventional display region maintains higher density for uniform display performance.
Solution Approach 2:
The display region is segmented into a conventional display region and a function display region with different circuit design parameters. This segmentation allows independent optimization of each region - the conventional region for display uniformity and the function region for light transmittance and optical device integration.
2Area of stationary object
If the transparent display region is arranged in the display region (not non-display region) to achieve full-screen display, then full-screen display is achieved with narrower bezel, but display uniformity between transparent and conventional regions becomes difficult to maintain
Solution Approach 1:
Different fixed potential line configurations are used in different regions: the conventional display region uses a first configuration optimized for display uniformity, while the function display region containing the optical device uses a second configuration with lower line density optimized for light transmittance and optical performance.
Solution Approach 2:
The display panel is divided into distinct regions with different circuit designs - the conventional display region and the function display region - allowing each to be optimized for its specific function while working together to achieve full-screen display with narrow bezel.
3Illumination intensity
If the density of second fixed potential lines is reduced to increase light transmittance, then light transmittance is improved, but display uniformity may be impacted
Solution Approach 1:
The patent implements location-specific fixed potential line density: the function display region has reduced density of second fixed potential lines to maximize light transmittance where the optical device operates, while the conventional display region maintains higher density to ensure display uniformity, creating locally optimized performance in each region.

AI summary
A display panel and a display apparatus are provided. The display panel has a conventional display region and a function display region for arranging an optical function element, and includes first pixel circuits and first fixed potential lines that are located in the conventional display region and electrically connected to the first pixel circuits, and further includes second pixel circuits and second fixed potential lines that are located in the function display region and are electrically connected to the second pixel circuits. A distance between two adjacent first fixed potential lines of the first fixed potential lines is greater than a distance between two adjacent second fixed potential lines of the second fixed potential lines.
