Display Panel Scan Line Segmentation for Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face challenges in enhancing the sensing sensitivity of electronic modules, particularly due to limitations in the design of display panels that affect the transmission and reception of signals and external inputs.
Innovation Solution
The display panel is designed with distinct areas of varying light transmittance and resolution, featuring a first display area with high resolution and low light transmittance, and a second display area with lower resolution but higher light transmittance, where the electronic modules are positioned below the second area to improve signal transmission and sensing sensitivity.

Engineering Contradiction Analysis
1Measurement precision
If the display panel uses a uniform high-resolution structure across the entire display area, then the display quality is maintained, but the sensing sensitivity of electronic modules is reduced due to blocked signal transmission
Solution Approach 1:
The display panel is divided into a first display area with high resolution and a second display area with lower resolution. This segmentation allows different regions to serve different functions: the first area maintains high display quality while the second area provides enhanced signal transmission for electronic modules, thus resolving the contradiction between sensing sensitivity and display resolution.
Solution Approach 2:
Different display areas are assigned different resolution characteristics tailored to their specific functions. The first display area uses high resolution for primary display content, while the second display area uses lower resolution to maximize light transmittance and signal transmission, allowing each local region to optimize its properties for its intended purpose.
2Reliability
If the display panel increases light transmittance in certain areas to improve electronic module sensing, then the sensing sensitivity is enhanced, but the display resolution in those areas is reduced
Solution Approach 1:
The display panel is divided into a first display area with high resolution and a second display area with lower resolution. This segmentation allows different regions to serve different functions: the first area maintains high display quality while the second area provides enhanced signal transmission for electronic modules, thus resolving the contradiction between sensing sensitivity and display resolution.
3Reliability
If scan lines are continuously connected across the entire display panel, then the electrical connectivity is maintained, but the light transmittance and sensing sensitivity are reduced due to overlapping with open areas
Solution Approach 1:
The scan line structure is segmented such that in the second display area, scan lines are disconnected in open areas and connected through bridge lines in light emitting areas. This allows electrical connectivity to be maintained while maximizing light transmittance in open areas, thereby improving sensing sensitivity without sacrificing electrical connectivity.
Solution Approach 2:
Bridge lines serve as intermediary elements that connect scan lines across open areas. Instead of having scan lines directly overlap open areas (which would block signal transmission), the bridge lines provide an indirect connection path through the light emitting areas, maintaining electrical connectivity while preserving signal transmission capability.

AI summary
A display panel includes a first display area and a second display area. The display panel includes a plurality of first pixel groups in the first display area, a plurality of second pixel groups in the second display area, and a plurality of scan lines connected to the first and second pixel groups. The second display area includes a plurality of light emitting areas in which the second pixel groups are respectively disposed, and a plurality of open areas in which the second pixel groups are not disposed. One of a second pixel group of an n-th row is cut and does not overlap an adjacent open area of the n-th row, and is connected in the second display area to a scan line of a second pixel group of an (n−1)-th row or a scan line of a second pixel group of an (n+1)-th row.
