Display Panel Shielding Structure for Signal Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current OLED display products face performance issues due to mutual interference between touch control signals and other signals, which affects their reliability and efficiency.
Innovation Solution
A display panel design featuring an isolation structure and a shielding structure in the same layer, with the shielding structure located in the non-display area to minimize signal interference and simplify manufacturing by allowing simultaneous processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If touch control component is placed in the non-display area, then touch control function is integrated, but signal interference with display signals increases
Solution Approach 1:
A shielding structure is introduced as an intermediary element between the touch control component and the display signal lines. This shielding structure acts as a mediator that blocks electromagnetic interference from the touch control signals from affecting the display signals, thereby resolving the signal interference problem while maintaining the integrated touch control function in the non-display area.
Solution Approach 2:
The non-display area is segmented into different functional zones: a touch control component area and a display signal area, with a shielding structure separating them. This segmentation allows the touch control function to be integrated while physically isolating it from display signals to prevent interference.
2Ease of manufacture
If isolation structure and shielding structure are arranged in the same layer, then manufacturing process is simplified, but structural complexity increases
Solution Approach 1:
The isolation structure and shielding structure are merged into the same layer, forming an integrated structure that performs both isolation and shielding functions simultaneously. This merging reduces the number of manufacturing steps by processing both structures in one go, while the unified design actually simplifies rather than complicates the overall layer structure.
Solution Approach 2:
The structure in this layer is designed to serve multiple functions: both isolating different functional areas and shielding against electromagnetic interference. This multi-functionality is achieved through a single integrated structure, reducing manufacturing complexity while providing comprehensive protection.

AI summary
A display panel and a display apparatus. The display panel includes a display area and a non-display area, and the display panel further includes: an array base plate; a light-emitting layer arranged on the array base plate and including a plurality of light-emitting units; an isolation structure located in the display area, the isolation structure being arranged on the array base plate and including a plurality of isolation openings, the light-emitting units being located within the isolation openings; a first shielding structure located in the non-display area and arranged in the same layer as at least a portion of the isolation structure; and a touch control component at least partially located at a side of the first shielding structure away from the array base plate.
