Terminal Device Screen Display and Execution Instruction Management

The terminal device stores multiple screen display instructions and execution instructions locally before they are needed. When a function is to be executed, the terminal device can immediately display the corresponding screen information without waiting for server transmission, thus reducing communication load while maintaining accurate timing.

The patent implements local storage of screen display instructions and execution instructions in the terminal device, allowing each terminal to independently manage its own instruction set. This localizes the information processing capability, reducing dependency on continuous server communication while ensuring accurate timing for information display.

The patent divides instructions into two distinct types: screen display instructions and execution instructions. Each type is stored and processed separately in the terminal device, with clear differentiation in their purposes. This segmentation simplifies the management logic by creating distinct handling paths for each instruction type, reducing overall complexity despite the multiplicity of instructions.

Instead of the server managing screen transitions and sending complete screen images, the patent inverts the approach by having the terminal device store and process instruction sets locally. The terminal autonomously determines when and how to display information based on stored instructions, reversing the traditional client-server display management model and reducing communication overhead.

The patent uses instruction sets that can be copied and stored in the terminal device. These instructions contain the necessary information to generate or retrieve screen displays without storing actual image data. The terminal device can reproduce the required screens by executing the stored instructions, enabling support for multiple device types and services without proportionally increasing image data storage requirements.

The patent employs parameter-based instruction sets that can be configured for different device types and services. By changing parameters within the instruction structure rather than storing different complete image sets, the system achieves high adaptability across multiple device types and services while maintaining constant storage requirements for the instruction templates.
