Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transparent display technologies face challenges in achieving high transparency and effective light shielding for display elements, leading to issues such as slit diffraction and reduced display quality due to gaps between gate lines.
Innovation Solution
Incorporating a light-shielding layer to cover the gap between gate lines and using a simplified layer structure without planarization and black matrix in the wiring area to enhance transparency and reduce slit diffraction.

1Object-affected harmful factors
If a light-shielding layer is added to cover gaps between gate lines, then light reflection and diffraction are reduced, but device complexity increases
Solution Approach 1:
The patent extracts and removes the planarization layer and black matrix layer from the wiring area, keeping only the essential light-shielding layer. This selective removal simplifies the overall layer structure while maintaining the critical light-shielding function needed to reduce reflection and diffraction in the transparent display panel.
Solution Approach 2:
The patent applies different layer configurations to different regions of the display panel. The wiring area has a simplified structure with only the light-shielding layer, while the pixel area maintains the full layer structure including planarization and black matrix layers. This local differentiation optimizes both transparency in wiring areas and display quality in pixel areas.
2Illumination intensity
If planarization layer and black matrix are removed in wiring area, then transparency is enhanced, but manufacturing precision requirements increase
Solution Approach 1:
The patent implements local quality by applying different layer structures to different functional areas. The wiring area uses a simplified structure without planarization and black matrix layers to maximize transparency, while the pixel area retains the complete layer structure for optimal display performance. This regional differentiation allows each area to be optimized for its specific function.
Solution Approach 2:
The display panel is segmented into distinct functional zones (wiring area and pixel area) with different structural requirements. This segmentation allows the wiring area to be optimized for light transmission while the pixel area is optimized for light emission and control, with each zone having its own tailored layer configuration.

AI summary
A display panel and an electronic device are provided. The display panel includes: a base substrate; and a plurality of pixels arranged in an array on the base substrate, the plurality of pixels including a first pixel and a second pixel. The first pixel includes a first light-transmitting area and a first display area that are sequentially arranged in a first direction, and the second pixel includes a second light-transmitting area and a second display area that are sequentially arranged in the first direction. The first pixel and the second pixel are adjacent in a second direction substantially perpendicular to the first direction, and the first light-transmitting area and the second light-transmitting area are adjacent in the second direction. The display panel further includes: a first gate line and a second gate line both arranged between the first light-transmitting area and the second light-transmitting area that are adjacent in the second direction, and the first gate line and the second gate line both extend in the first direction. The first light-transmitting area is contiguous to the first gate line, and the second light-transmitting area is contiguous to the second gate line.
