Solution Overview
Problem
Existing display technologies face challenges in minimizing the border area of abnormal-shaped display panels, such as those with rounded corners or arc-shaped edges, which limits the display region proportion in modern electronic devices.
Innovation Solution
The design of an organic light-emitting display panel with gate drive units and light-emitting control units arranged along an arc, featuring straight portions with included angles less than 180°, allowing for a more effective arrangement that reduces the border width and increases the display region proportion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the display panel uses a conventional rectangular layout with rounded corners, then the manufacturing process is simple, but the border area is large which reduces the display region proportion
Solution Approach 1:
The patent applies curvature by arranging gate drive units and light-emitting control units along an arc-shaped boundary rather than a straight line. The arc has a curvature radius R that satisfies R≥10mm, allowing the display panel to achieve rounded corner effects while minimizing border area. This curved arrangement enables the display region to extend closer to the physical boundaries, increasing the display region proportion from conventional levels to over 90% of the total panel area.
2Device complexity
If the light-emitting control units are arranged in a straight line, then the circuit design is simple, but the border width cannot be reduced for arc-shaped edges
Solution Approach 1:
The light-emitting control units are arranged along an arc with curvature radius R≥10mm, matching the rounded corner geometry. This arc-shaped arrangement allows the control units to follow the curved boundary, reducing the border width at the corners while maintaining manageable circuit complexity through systematic routing of gate lines and data lines along the curved paths.
Solution Approach 2:
The patent transitions from a one-dimensional straight-line arrangement of control units to a two-dimensional arc-shaped distribution. By utilizing the curved boundary dimension, the display panel can better utilize the available space at rounded corners, reducing border width while the systematic routing of signal lines maintains circuit manageability.
3Shape
If the display panel has arc-shaped edges with large curvature radius, then the aesthetic appearance is improved, but the border area increases which reduces display region proportion
Solution Approach 1:
The patent optimizes the curvature radius R to satisfy R≥10mm, which provides aesthetically pleasing rounded corners while minimizing the border area. This specific curvature range achieves the right balance between visual appeal and space utilization, allowing the display region to extend as close as possible to the physical boundaries while maintaining smooth rounded corners.
Solution Approach 2:
The gate drive units and light-emitting control units are selectively arranged along the arc-shaped boundary where needed, rather than uniformly across the entire panel. This localized arrangement at the curved edges allows the display region to occupy the maximum area while the control units are concentrated in the border regions, achieving both aesthetic appearance and high display region proportion.
