Framework Layer Slide Drawing Control Rights Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display processes in terminal devices suffer from excessive redundant operations, leading to long system response times, low display efficiency, and high power consumption, particularly during repetitive image composition in touch-display procedures.
Innovation Solution
The framework layer transfers slide drawing control rights to itself from the application layer, utilizing shared memory to acquire and process touch point data, predicting user operations, and optimizing image drawing near the hardware layer, thereby reducing redundant processing and improving system responsiveness.

1Productivity
If touch event processing follows the traditional layer-by-layer reporting from driver layer to application layer and back, then the system maintains a fixed and standardized processing flow, but this results in excessive redundant operations, long system response time, low display efficiency, and high power consumption
Solution Approach 1:
The patent extracts the image composition operation from the traditional multi-layer processing flow and places it directly at the driver layer. This extraction eliminates the need for touch events to traverse up to the application layer and back down, removing redundant processing steps and significantly reducing system response time while improving display efficiency
Solution Approach 2:
The patent segments the processing flow by identifying that only specific operations (image composition) need to be handled at the driver layer, while other processing can remain at higher layers. This segmentation allows the system to optimize critical path operations without compromising the overall layered architecture
2Productivity
If touch event processing follows the traditional layer-by-layer reporting from driver layer to application layer and back, then the system maintains a fixed and standardized processing flow, but this results in excessive redundant operations consuming a large quantity of system resources, particularly power
Solution Approach 1:
The patent extracts the image composition operation from the traditional multi-layer processing flow and places it directly at the driver layer. This extraction eliminates the need for touch events to traverse up to the application layer and back down, removing redundant processing steps and significantly reducing system response time while improving display efficiency
Solution Approach 2:
The driver layer performs image composition operations autonomously without requiring intervention from upper layers. This self-service capability at the driver layer eliminates redundant processing and reduces power consumption by handling operations locally where the data resides

AI summary
A display method of a terminal device and a terminal device is provided. The display method of a terminal device includes: a framework layer sends a first touch point data; an application layer sends instruction information used to instruct to transfer slide drawing control rights to the framework layer and a generated display list to the framework layer after the application layer determines that the terminal device enters a sliding state according to acquired first touch point data; and the framework layer acquires second touch point data from a shared memory according to the instruction information, and draws an image according to the second touch point data and the display list. In this way, in an operation with repetitive image composition, the slide drawing control rights are transferred from an application module to a framework module, improving a response speed of a terminal system.
