Display Panel Wiring Layout for Camera-Area Light Transmittance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels with high screen-to-body ratio face challenges in achieving sufficient optical transmittance for camera areas, as the normal luminous zone's transmittance is insufficient to meet camera demands, leading to poor imaging quality.
Innovation Solution
The display panel is designed with alternating wiring groups in two areas, where the second wiring group is rearranged outside the second display area to increase light transmittance, and the wiring arrangement is adjusted to create a larger blank area between adjacent first wiring groups, enhancing light transmittance and imaging quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If high PPI is used in normal area and low PPI is used in camera area, then overall transmittance of camera area is improved, but imaging quality is insufficient due to inadequate transmittance
Solution Approach 1:
The patent applies local quality by implementing different wiring arrangement strategies in different display areas. The first wiring groups (connecting to pixel units) and second wiring groups (connecting to sensor units) are arranged alternately in the first display area, while in the second display area, the wiring groups are arranged to create larger blank areas. This localized differentiation optimizes transmittance in the camera area while maintaining display quality in the normal area.
Solution Approach 2:
The patent resolves the transmittance limitation by transitioning from a uniform two-dimensional pixel arrangement to a three-dimensional wiring arrangement strategy. By alternating first and second wiring groups in different areas and creating varied blank area patterns, the design adds a dimensional layer of complexity to the wiring layout, enabling optimized light paths from multiple angles and improving overall transmittance without compromising imaging quality.
2Adaptability or versatility
If wiring groups are arranged alternately in first display area, then display function is maintained, but transmittance in second display area is insufficient for camera imaging
Solution Approach 1:
The patent segments the display panel into two distinct functional areas: a first display area where alternating first and second wiring groups maintain display functionality, and a second display area (camera area) where wiring groups are arranged to prioritize light transmittance. This segmentation allows each area to be optimized for its specific function while maintaining overall system versatility.
Solution Approach 2:
The patent achieves multi-functionality by enabling the second display area to serve dual purposes: it can function as a display area when imaging is not required, and as a camera area when imaging is needed. The alternating wiring arrangement with optimized blank areas allows the same physical structure to support both display and imaging functions, enhancing adaptability without requiring separate dedicated areas.
3Illumination intensity
If blank area between wiring groups is increased in second display area, then light transmittance is improved, but wiring density is reduced
Solution Approach 1:
The patent applies asymmetry by creating non-uniform wiring arrangements between the first and second display areas. In the first display area, wiring groups are arranged with standard spacing to maintain display quality. In the second display area, the wiring groups are arranged with larger blank areas and asymmetric patterns to maximize light transmittance. This asymmetric design allows optimization for different functional requirements in different areas.
Solution Approach 2:
The patent introduces dynamic adaptability through the alternating wiring arrangement that can be configured differently in different areas. The wiring layout is not fixed but can be dynamically adjusted in terms of spacing and arrangement patterns to meet the specific requirements of each display area, balancing transmittance needs with wiring density requirements.
