Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The curvature of the peripheral area of the display screen in mobile terminals causes variations in touch control, leading to unsmooth sliding operations due to differences in touch control differences between the curved edge area and the flat middle area.

Innovation Solution

A touch control processing method that differentiates between sliding instructions initiated from the edge area and those from the near-edge area, collecting frame coordinates to determine the sliding direction and applying point supplementation at symmetrical positions in the edge area to smooth out sliding operations.

Solution Approach 1:

The display screen is divided into three distinct areas: edge area, near-edge area, and middle area. Different processing methods are applied to each area based on its characteristics. The edge area uses one processing method while the near-edge and middle areas use another method, allowing optimized touch control for each region while maintaining overall sliding smoothness.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different touch control processing methods are applied to different areas of the display screen based on their local characteristics. The edge area receives specialized processing to compensate for curvature effects, while the near-edge and middle areas receive standard processing, ensuring optimal sliding performance in each local region.

Inventive Principle:

2Device complexity

If touch control processing is applied uniformly across the entire display screen, then the processing complexity is reduced, but the sliding operation smoothness deteriorates due to inability to handle edge area curvature variations

Engineering Contradiction:

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The display screen is segmented into three areas (edge area, near-edge area, and middle area) with distinct processing methods applied to each. This segmentation allows the system to handle the complexity of curvature variations in the edge area while maintaining simpler processing in the near-edge and middle areas, achieving a balance between processing complexity and sliding smoothness.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system applies different processing methods to different areas based on their local characteristics. The edge area receives specialized curvature-compensating processing, while the near-edge and middle areas receive standard processing, optimizing sliding smoothness without unnecessarily increasing processing complexity across the entire screen.

Inventive Principle:

Solution Approach 1:

The display screen is divided into three areas with different processing methods. The edge area uses a specialized method to handle curvature variations and maintain sliding smoothness, while the near-edge and middle areas use the standard method. This segmentation allows the system to maintain touch control consistency across the entire screen while optimizing for the specific needs of the edge area.

Inventive Principle:

Solution Approach 2:

Different processing methods are applied to different areas based on their local characteristics. The edge area receives specialized processing to maintain sliding smoothness despite curvature, while the near-edge and middle areas receive standard processing. This local differentiation ensures both sliding smoothness in the edge area and overall touch control consistency.

AI summary

A touch control processing method is applied to a mobile terminal. A display screen of the mobile terminal is configured with an edge area and a near-edge area that are connected, the edge area is located at a peripheral edge position of the display screen, the edge area surrounds the near-edge area. The method is used to, when receiving a touch control instruction inputted by a user, and determining that a first frame coordinate is in the near-edge area and a sliding direction of the sliding instruction is not toward an original area, supplement a point coordinate supplement at a position in the edge area symmetrical to the second frame coordinate about the first frame coordinate, which is taken as a datum, opposite to the sliding direction.
