Curved Display Panel Structure to Reduce Swiping Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels suffer from motion interference due to the height difference between the front frame and display portion, causing finger contact with the frame edge during screen swiping.
Innovation Solution
The display device incorporates a design with a display portion comprising a plane and arc surface display portion, an encapsulation structure, and a supporting layer with matching sub-portions to equalize the horizontal plane heights, reducing the front frame height and eliminating interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If pad bending technology is used to reduce frame size and improve screen-to-body ratio, then the frame size is reduced, but the front frame height becomes greater than the display portion height, causing motion interference
Solution Approach 1:
The display portion is designed with an arc-shaped surface that transitions from the bending portion to the plane display portion. This curved design allows the display surface to follow the bent contour of the flexible substrate, enabling the front frame height to be reduced to match or be lower than the display portion height, thereby eliminating motion interference while maintaining a compact frame structure
Solution Approach 2:
The invention transitions from a traditional flat display surface to a three-dimensional arc-shaped display surface. By utilizing the vertical dimension and creating a curved transition zone, the display portion can accommodate the bent substrate without requiring additional front frame height, thus resolving the contradiction between compact frame size and operational comfort
2Area of stationary object
If pad bending technology is used to reduce frame size, then the frame size is reduced, but the height difference between front frame and display portion causes fingers to touch the frame edge during swiping
Solution Approach 1:
The arc-shaped display portion creates a smooth curved surface that transitions from the bent substrate to the flat display area. This curvature ensures that the display surface height is consistently maintained across the bending region, preventing any protruding frame edges that could interfere with finger swiping motions
3Stability of the object's composition
If the front frame height is increased to accommodate the bending portion, then the bending portion can be housed, but the height difference causes motion interference and poor aesthetics
Solution Approach 1:
Instead of creating a flat protruding frame to accommodate the bending portion, the invention uses a curved arc-shaped display surface that naturally follows the bent substrate contour. This allows the bending portion to be housed within the display area itself, eliminating the need for additional front frame height and preventing motion interference

AI summary
A display device and a mobile terminal are provided in embodiments of the present application. A display portion of a display panel in the display device provided in the embodiments includes a plane display portion and a first arc surface display portion connected to the plane display portion and a bending portion. In a direction of a light-emitting side of a display module, a height of a horizontal surface where a top surface of an encapsulation structure is located is greater than or equal to a height of a horizontal surface where a top surface of a front frame is located, so as to eliminate occurrence of motion interference caused by a touch between fingers and an edge of the front frame when swiping a screen in prior art.
