Corner Display Transistor Layout for Seamless Edge Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with curved edges often have a non-display area that becomes visible to users, disrupting the seamless visual experience.
Innovation Solution
The display device incorporates a design with distinct display areas in the corner portions, including cutout portions and sensor lines that do not overlap emission areas, ensuring a continuous display without visible non-display regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a non-display area is disposed between the front display area and the corner display area, then the manufacturing and wiring are simplified, but the non-display area becomes visible to users disrupting the visual experience
Solution Approach 1:
A light-shielding film is introduced as an intermediary element between the front display area and the corner display area. This film is disposed in the non-display area to prevent light leakage and make the non-display area invisible to users, thereby resolving the contradiction by maintaining wiring simplicity while eliminating the harmful visibility effect
Solution Approach 2:
The light-shielding film utilizes optical properties (color/opacity changes) to block light transmission in the non-display area. By making the non-display area optically opaque, the film prevents users from seeing through it, thus hiding the non-display area while maintaining the simplified manufacturing structure
2Reliability
If the sensor lines overlap with the emission areas, then the sensor coverage is maximized, but the display quality deteriorates due to line visibility
Solution Approach 1:
The sensor lines are routed through the non-display area, utilizing the spatial dimension that is not occupied by emission areas. This allows the sensor lines to maintain full coverage and connectivity while being positioned in a region where they will not be visible to users, thus resolving the contradiction between sensor coverage and display quality

AI summary
A display device includes a display panel including a front portion, a first side portion which extends from a first side of the front portion, a second side portion which extends from a second side of the front portion, and corner portion disposed between the first side portion and the second side portion. The display panel includes a first display area disposed in the front portion and including a plurality of first emission areas and a plurality of sensor electrodes, and a second display area disposed in the corner portion and including a plurality of second emission areas and a plurality of first sensor lines electrically connected to at least some of the sensor electrodes.
