Four-Sided Curved Flexible Display Panel for Higher Screen-to-Body Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with curved screens face limitations in increasing the screen-to-body ratio and product competitiveness due to fixed appearances resulting from uncurved top and bottom frames, leading to poor user experience and reduced display efficiency.
Innovation Solution
A flexible display panel design with additional curved shapes at the top and bottom, featuring a main view portion and three side view portions that bend towards the back face, allowing for a four-curved screen configuration without generating wrinkles, and a light-transmitting cover plate with corresponding arc sheet portions to enhance aesthetics and fitment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the flexible display panel is curved only on two sides without curving at top and bottom, then the panel structure is simpler and easier to manufacture, but the screen-to-body ratio cannot be further increased and the appearance becomes fixed with poor product competitiveness
Solution Approach 1:
The patent applies curvature to all four sides of the flexible display panel, transforming the panel from a partially curved structure to a fully curved structure. This is achieved by configuring the first and second side view portions to extend from the first and second sections respectively and bend toward the back face side, while the third side view portion connects between them and also bends toward the back face side. This comprehensive curvature application increases the screen-to-body ratio and creates a more aesthetically pleasing appearance without compromising manufacturing feasibility
2Area of stationary object
If the flexible display panel is curved at all edges including corners, then the screen-to-body ratio increases and aesthetics improve, but the processing difficulty of the middle frame increases due to upwarp corners
Solution Approach 1:
The patent implements different curvature characteristics in different regions of the display panel. The first and second side view portions have curvature that bends toward the back face side, while the third side view portion at the corner has a different configuration that reduces the upwarp effect. This localized differentiation of curvature properties allows the panel to achieve high screen-to-body ratio while minimizing the processing difficulty of the middle frame
3Ease of manufacture
If the flexible display panel has curved shapes on sides but not at top and bottom, then the manufacturing process is simpler, but the black edge width at corners is inconsistent with sides resulting in poor appearance
Solution Approach 1:
The patent creates a unified curvature design that applies consistently across all four sides of the display panel. The first, second, and third side view portions are all configured to bend toward the back face side, creating consistent black edge widths at corners and along the sides. This universal curvature approach ensures aesthetic consistency while maintaining manufacturing simplicity through a standardized design methodology

AI summary
A flexible display panel includes a main view portion, and a first side view portion, a second side view portion, and a third side view portion that are disposed at an edge of the main view portion, where the third side view portion is connected between the first side view portion and the second side view portion; and the first side view portion, the second side view portion, and the third side view portion respectively extend from a first section, a second section, and a corner section of the main view portion in a direction leaving a middle portion of the main view portion and bend toward a back face side.
